Why is your core so important?

By Courtney White, Registered Physiotherapist

Have you ever wondered what makes up your core, why is it important, or how to safely train your core without getting back pain? Keep on reading to find out these answers and more!

Your core is more than just the muscles that you can see. There is a group of muscles below the big six pack muscles that wrap around you like a corset. Their job is to support you during every movement. This inner unit is like a TRANSFER STATION. To get power generated from your legs all the way to your shoulders, it must pass through the inner core. So, if you do not have proper control over your core, that power will not move between your upper and lower body as smoothly as you want it to.

What Makes Up the Inner Core Unit?

The inner core consists of the following: the diaphragm, the pelvic floor, transversus abdominus (TA), and multifidus. Collectively, these 4 structures create a CORE CANISTER.IMG_5235-01Pic for Core

Diaphragm: The diaphragm is our primary breathing muscle and it forms the top of the core canister. The diaphragm is the component that has the primary control over the intraabdominal pressure within the canister. It moves up and down as you breathe which changes the space in the abdomen and as a result, influences the pressure within the core canister.

Pelvic Floor: The pelvic floor is a group of muscles that form the bottom of the canister. It supports the weight of all the internal organs within our abdomen, assists with bowel and bladder control, and helps to control the intrabdominal pressure along with the diaphragm. The pelvic floor is partners with the diaphragm. When the diaphragm moves up and down, so should the pelvic floor.

Transversus Abdominis (TA): This muscle connects the top and bottom of the canister as well as creates the front and sides of the core canister. It runs deeper than the external six pack muscles that you can see. Its role is to support your lower back during movement and transmit forces between your upper and lower body.

Multifidus: This muscle forms the back of the core canister and runs along the spine. Multifidus serves as a primary support for the spine, pelvis, and hips.

What Are the Functions of the Core Canister? 

  1. To support the back, pelvis, hips, and trunk during movement
  2. To serve as a transfer station for power and energy between the upper and lower body
  3. To assist with bowel and bladder control
  4. To improve performance during physical activity

How Does the Core Canister Work?

To gain a stronger core overall, it is important to learn how to “pressurize” the core canister. Previously, inner core training has focused largely on tensing the walls of the core canister through focused contractions of TA. Learning how to activate the diaphragm and pelvic floor was often missed or brushed over. More recent evidence now suggests that breath is the driving force behind influencing the intrabdominal pressure. Therefore, the diaphragm is the leader behind pressurizing the core.

When you breathe in, your diaphragm contracts and pushes down into the abdominal cavity which increases the intraabdominal pressure. In response to this increased pressure, the pelvic floor relaxes and lengthens to accommodate the abdominal organs translating downward. During your inhale, the pressure in the front part of the core canister is increased as your belly expands. This is counteracted by multifidus in the back as well as TA which work together to try and keep the intraabdominal pressure evenly distributed. When you breathe out, the diaphragm relaxes and rises which decreases the pressure within the core cannister. As a result, the pelvic floor should normally contract and rise.

How Do We Train the Core Canister? 

Many people focus on crunches, planks, and other large abdominal exercises when training the core but negate breathing. Learning to connect your breath with movements is the key to developing a stronger core. It will allow you to control the intrabdominal pressure within the core canister. Exercises like planks and crunches are not necessarily bad exercises as they can be very effective later if you first learn to optimize the control of your core canister.

The first step is to learn how to engage your diaphragm through diaphragmatic umbrella breathing. Once you have achieved this, it is time to add in the pelvic floor so that you learn how to engage your diaphragm and pelvic floor together as a unit, referred to as piston breathing. You can also learn how to connect and activate TA and multifidus to further optimize your control over the core canister. However, it is important to highlight that the goal here is to learn how to change the size of your core canister by recruiting all these muscles together, rather than focusing solely on how to contract each specific muscle. Once you have learned how to control the pressure within the core canister, it is now time to perform bigger movements that require you to maintain control over the canister while doing a larger activity.

Check out our post on our Facebook and Instagram pages (dated May 21, 2020) for exercises you can try at home to increase your control of the core canister!

What Can Happen If You Do Not Have Control Over Your Core? 

It is not uncommon to have a weak inner core or lack control over your core canister. This can originate from prolonged sitting and slouching which distorts and changes the shape of the core canister (see part B in Figure 3 below). This positioning leads to breathing through the accessory muscles in your neck and chest, decreasing the engagement of your diaphragm. As you can see in the figure below, this puts a lot of strain on the lumbar spine which can lead to pain and injury. Ideally, your core canister should look something like part A in the figure below where the intraabdominal pressure is equally distributed. Without proper control over your inner core, it makes it very difficult for you to be able to hold your body in a good position during exercise and physical activity. This increases your risk for injury.

Concussion Management Part 2: How Long Does Recovery Take?

By Cassandra Kroner, PT

In part 1 of the concussion management blog series we covered how the brain is affected following a concussion, common symptoms, why early intervention is critical, and how physiotherapy can help optimize recovery. One of the most frequent questions people have following a concussion is about recovery time – ‘when can I go back to work full time?’ or ‘when can my son/daughter play soccer again?’. It can be helpful to understand the general stages of injury and potential progression of symptoms:

concussion blog image_jan2019

The initial days following a concussion are considered the acute stage of injury, and cognitive and physical rest is critical at this time. After 7-10 days of adequate rest the chemical balance and blood flow in the brain has been restored, and symptoms that continue are known as post-concussion syndrome. Some symptoms can last upwards of 6 months or years post injury. It is important to keep in mind that not everyone will progress through all three stages, and the length of time symptoms last will vary between individuals.

Why Recovery Can Take Longer

There are a number of factors that can complicate and prolong recovery, and these can help us predict if symptoms are likely to persist longer than the usual 6 weeks. A history of migraines, mental health conditions such as depression or anxiety, or learning disabilities, have been found to increase recovery times. Additionally, visual or vestibular dysfunction or a high number of initial symptoms following a concussion usually indicate prolonged recovery.

History of Concussion

People who have had a previous concussion are more susceptible to have another one due to a lower threshold for injury after each concussion – meaning the next concussion can happen from a lower severity injury than the first time. Additionally, there is often an increased number of symptoms and a longer recovery time after each subsequent concussion. A concussion at a young age risks disruption of brain circuits yet to be developed, and also creates a wider window for repeated future concussions.

Repetitive hits that are common in sports such as hockey or football, which do not cause a concussion, are known as sub concussive trauma. Research has shown this repetitive trauma can result in increased reaction and processing time, memory impairments and increased chance of making mistakes. These effects can place an athlete at an increased risk for a concussion during sport. If the athlete does sustain a concussion at this point, the brain has a diminished reserve capacity to manage injury, and the effects of subsequent concussions are cumulative and result in increased impairment in function with each concussion.

Additional Injuries

Another complicating factor is the presence of other injuries, such as whiplash or neck sprain/strains, that can occur with falls or car accidents. These neck injuries alone can cause similar symptoms to a concussion including headaches and dizziness, and in combination with a concussion can result in more severe and prolonged symptoms. Having an assessment by a physiotherapist can determine which symptoms are from the neck injury and which are from the concussion – resulting in individualized treatment strategies to target the cause of each symptom.

To conclude, although concussions can be an invisible injury, they need to be properly managed and rehabilitated just like any other injury. This management includes assessment to determine the cause of symptoms, specific treatments to address each impairment, and strategies to manage recovery at home. Visiting a physiotherapist trained in concussion rehabilitation will ensure that both concussion symptoms and neck injuries are addressed. The goals of treatment are to restore physical and cognitive function while facilitating a safe return to work and sport. Awareness and education about concussions and treatment options are important to ensure that people don’t suffer unnecessarily from prolonged symptoms – this is where a trained Physiotherapist can help!

Osteoporosis and Exercise

By Lauren Harding, Registered Kinesiologist

What is osteopenia and osteoporosis?

unnamedOsteopenia and osteoporosis are conditions characterized by a loss of bone mineral density (BMD). BMD is a measure of the quantity of minerals (calcium and phosphorus) in a precise volume of bone. The difference comes in their severity.

Osteopenia indicates a lower BMD causing bones to be generally weaker. This bone weakness becomes more pronounced with osteoporosis as the bones become more brittle and porous (filled with air pockets), ultimately increasing the risk of fracture. Though less severe, osteopenia is a serious risk factor for developing osteoporosis.

Osteoporosis is often labeled as the ‘silent thief’ since bone loss occurs gradually, typically without symptoms. However, these four factors can signal underlying osteoporosis:

  • Loss of height over time and/or development of a stooped posture
  • Sudden back pain without any obvious cause
  • Fracturing after a seemingly minor incident

 

How are these three conditions treated?

An excellent approach is early intervention physiotherapy treatment, accompanied by a well-designed exercise program. It is important to consult your doctor before starting a new exercise plan. As with any exercise, there is always risk associated.

Osteoporosis Canada recognizes exercise not only for increasing cardiovascular endurance, but also as a fundamental component to protecting your bones. Exercise maintains bone mass and builds muscle strength, as well as increases flexibility and range of motion, balance and coordination. Benefits also include reduced pain and inflammation, while promoting loss of excessive weight. Additionally, the risk of falling is reduced.

 

What types of exercise should I be doing?

There are 5 types of exercises recommended for individuals with osteopenia and osteoporosis:

Types of Exercise How Often Should I Do These?
Aerobic 3 to 5 days per week, a minimum of 150 minutes per week
Strength Training 2 to 3 times per week
Balance Every day
Stretching Every day
Posture Training Always

 

Aerobic Exerciseunnamed

Aerobic exercise is considered any continuous, rhythmic activity that strengthens and stimulates the heart and lungs, thereby improving the body’s use of oxygen. It is recommended that ALL adults get 150 minutes of moderate to vigorous physical activity a week, or about 20 to 30 minutes per day, for at least 10 minutes at a time. During moderate-intensity activity, your heart beats faster and you breathe harder. The rule of thumb is that you are able to talk during these activities, but you are working too hard to be able to sing. During vigorous-intensity activity, your heart beats faster still and you continue to breathe harder. You are unable to say more than a few words at a time during vigorous activity. It is important with osteopenia and osteoporosis to do weight bearing aerobic exercises. Examples of weight bearing aerobic exercises include:

  • Brisk walking, dancing, stair climbing, running, step aerobics, hiking, jogging, jump rope, and treadmill walking/running

 


Strength Training

Elderly_exercise

In order to increase your muscular strength, you must work against resistance until your muscles feel tired.

This helps to reverse muscle atrophy, a condition that occurs when your muscles start to waste away due to lack of use. Furthermore, resistance training strengthens the muscles surrounding your joints, ultimately reducing further joint damage and decreasing risk of injury. ALL adults should do 2-3 days of strength training a week. Exercises using free weights (dumbbells), exercise bands or weight machines are strongly recommended. Examples include:

  • bicep curls, sit-to-stand, lunges, rows, calf raises, bridges, triceps kickbacks, countertop push ups

 

Balance Exercises

Balance exercises help maintain your footing when an unexpected movement occurs in your daily life. Improving balance and coordination can reduce your likelihood of falling, therefore decreasing your fracture risk. Ironically, in challenging your balance, you run the risk of falling. For this reason, you must always take precautions such as having a chair nearby to hold onto. When you are training your balance, there are two main types of balance exercises:

  • Static Exercises – Stand still in one spot holding a certain posture in order to practice balance. For example, standing on one foot on the floor.
  • Dynamic Exercises – Balance is challenged more with adding movement. For example, walking ina straight line while touching the heel of one foot to the toe of the other with each step.

 

Stretching

unnamed (1)As you age, you lose flexibility which can increase your stiffness and discomfort, often preventing you from staying active. Stretching exercises help you to counteract this by increasing the range of motion of your joints and improving your flexibility. It is important to note that stretching should always be done after the muscles and the body are warmed up since stretching cold, stiff muscles increases your risk of injury. Just like in balance training, there are two main ways to stretch:

  • Static Stretching – Take the muscles to their end range of motion and maintain that position for at least 30 seconds in order to enhance soft tissue and muscular flexibility.
  • Dynamic Stretching – Functional, multi-joint movements that typically increase in range of motion and speed as the body begins to warm up.

While both are effective, dynamic stretching has been shown to be more beneficial than static stretching as a way to warm up prior to activity since it has been found to improve balance, strength, reaction time and agility. Static stretching, however, is still important and is most beneficial when performed at the end of exercise as a cool down. Static stretching can also be done separately when the body is warm as part of an everyday attempt to improve body mechanics, posture and flexibility.

 

Posture Training

unnamed (1)We all have a natural curve in our spine, however, weak back muscles and/or spinal fractures can cause an excessive forward curvature of the spine. Rounding of the upper back is known as exaggerated kyphosis. This puts pressure on the front of your vertebrae, placing them at even great risk of fracture. Posture training exercises help to improve the alignment of your spine by correcting shoulder, back and neck positioning. Focus should be placed on exercises that strengthen the back muscles and reduce forward head posture. Abdominal exercises that strengthen the core muscles, help to maintain good posture as well.

 

To Sum Up

An exercise program is a vital component in the management of osteoporosis.

Regular participation in aerobic and strength training is fundamental, as well as balance, posture management and stretching.  All in all, physical activity for individuals with osteopenia or osteoporosis can promote bone health and overall quality of life.

Concussion Management Part 1: The Role of Physiotherapy

By Cassandra Kroner, PT

What is a Concussion?

Concussions are a type of mild traumatic brain injury. Common causes include car accidents, sports, falls, or workplace accidents. Concussions can result from direct impact to the head, or from forces elsewhere in the body such as sudden acceleration or deceleration that cause an  injury to the brain and brain-stem.  The result is damage to cells and chemical imbalances that disrupt normal brain function.

Concussion Head imageImmediately following injury a sequence of chemical processes occur as the brain attempts to restore its normal balanced state. This increased activity in the brain is happening at a time when blood flow is decreased to the site of injury, creating an increased demand for energy. The resulting impairments in neurological function can cause a variety of signs and symptoms:

Physical Behavioural/Emotional Cognitive
Headache Drowsiness or fatigue Feeling foggy
Nausea Irritability Trouble thinking clearly
Vomiting Depression Feeling slowed down
Blurred or double vision Anxiety Difficulty concentrating
Balance problems Sleeping more than usual Difficulty remembering
Dizziness Difficulty falling asleep Trouble finding words
Sensitivity to light or noise Sadness Confusion

 

First Steps Following Injury

Concussions are often under-reported and misdiagnosed, and it is important to note that loss of consciousness is not necessary for a diagnosis. Contributing to the difficulty in identifying concussions is the lack of imaging or other tests to aid in diagnosis. Unless there is bleeding or swelling in the brain, the changes that occur with a concussion are not visible on a CT or MRI. If a concussion is suspected, an evaluation by a physician is recommended, and unless symptoms are severe or quickly worsening it is usually not necessary to visit the emergency room. Once the diagnosis is established and conditions requiring further medical treatment are ruled out, treatment should begin immediately.

Early Management

HeadacheTimely intervention following a concussion is essential to ensure optimal management and recovery. An outdated approach to concussion treatment is to stay in a quiet dark room until symptoms are resolved. With a growing demand for evidence-based treatment strategies, there is a wealth of new research that refutes this old-fashioned ‘dark room’ approach. Although complete rest is recommended for the first 48-72 hours after injury, research supports a more active approach to recovery following the initial rest period. Prolonged physical rest can lead to de-conditioning, depression and fatigue, making it more difficult to return to the previous level of physical activity.

Complete physical and cognitive rest immediately following a concussion is critical to ensure adequate energy supplies for the brain as it attempts to heal. Excess physical or cognitive exertion at this time will use precious energy that the brain needs and can result in exacerbation of symptoms and prolonged recovery. Physical rest means no exercising and caution with exertion around the house. Cognitive rest should focus on refraining from activities that require concentration (schoolwork, reading), as well as visual attention (television, video games, computer or phone use). Alternative options are listening to music or audio books.

Importance of Physiotherapy

A visit to a physiotherapist with advanced concussion management training is recommended for a detailed assessment following a concussion. Your physiotherapist will take a thorough history and can assess visual and vestibular symptoms, balance, cognitive function, and any additional injuries sustained at the time of concussion. Recommendations for the initial rest period as described above will be tailored to each individual, and further suggestions for management of symptoms will be provided.

Treatment plans involve a carefully monitored graded program of exertion to assist with a safe return to work/school and then sport. Every individual will experience a different set of symptoms following concussion, and as a result there is not a ‘one size fits all’ approach to treatment. This is why having a professional guide you through recovery is valuable. Specific and progressive exercises will be provided to target deficiencies in the vestibular and visual systems. To facilitate a gradual return to school or work, suggested accommodations would be provided to minimize symptoms and maximize participation. Additionally, manual therapy to address complaints such as neck pain or headaches can be part of treatment. Once the individual has returned to school or work, physical exertion testing is the last step before being cleared for sport.

Recovery time frames vary between individuals, but for many people, symptoms resolve in a month or less. However, there are a number of factors that can delay or prolong recovery. Stay tuned for part 2 of the concussion management blog series to learn more.

Physiotherapy after a Fracture

By Courtney Lacey, PT

fractureIf you have recently broken a bone, you may be wondering when you will be able to return to all of your normal activities. While it typically takes 4-8 weeks for a bone to heal, you will likely require physiotherapy to help get you back to full function.

How do fractures happen?

A broken bone, also known as a fracture, can occur in many ways. Most often, broken bones are the result of a traumatic mechanism of injury such as a fall, motor vehicle accident or contact during a sporting event. Fractures can also occur from repetitive motions which place stress on the muscles and bones. A common example of this is stress fractures in the legs from running. Finally, fractures can more easily occur in people with osteoporosis – a disease which weakens bones and makes them more likely to break.

How do you know if you have a fracture?

These are some signs and symptoms which may indicate that you have a fracture:

  • Immediate and severe pain following a fall or accident
  • A “pop” or “click” heard or felt during the incident
  • Swelling in the area
  • A bump or deformity
  • Unable to weight-bear through the injured limb

If you suspect you have a fracture, you will need to see a doctor who will order an X-ray to confirm the diagnosis. Often, those who experience an injury causing a fracture will go to the hospital to be evaluated.

Does a fracture heal?

While bone healing takes approximately 4-8 weeks, the timeline depends on both the person and the type of fracture.  In order for a bone to heal properly, it has to first be set in the proper position, which is called reduction. The doctor may be able to reposition the bones without surgery, which is called a closed reduction. Sometimes, surgery may be required to bring the ends of the bone close together, which is called an open reduction. Pins, plates or screws may also be used to keep the bones in place. If the fracture did not cause any part of the bone to shift out of place, no reduction is needed. Once the doctor has determined the bones are in a good position to allow for healing, the area will be immobilized in a cast or a splint.

When can the cast come off?

To determine if you are ready to have the cast removed, you will have an X-ray done with the cast or splint in place. The doctor will look for the formation of a callus, which demonstrates that healing has taken place. The doctor will then remove the cast and may recommend that you have physiotherapy. Physiotherapists play a key role in returning you to your full function as quickly as possible after a fracture.

Why do I need physiotherapy?

There are several reasons why physiotherapy is needed after fracture. Depending on the amount of healing that has occurred, your doctor may have special instructions (how much weight to put through the limb, certain activities to avoid, etc.) that your physiotherapist can help you understand. Once the cast is removed, you may still have some swelling and pain around the fracture site. Physiotherapists may use modalities (such as ultrasound or TENS) to help decrease pain and swelling and improve your mobility and tolerance for using the injured limb in daily activities. If you had surgery, you may also have a scar which creates scar tissue and can disrupt movement. At BodyTech Physiotherapy your therapist will use manual therapy techniques to help mobilize the scar tissue and the areas around the injury as needed to  restore normal movement around the surgical site.

Physiotherapy is crucial to improve your functional mobility that you may have lost during your time in the splint or cast. Immobilization over 6-8 weeks will cause loss of range of motion and strength, which will make daily tasks difficult to do. Your physiotherapist will help restore your proper range of motion using manual therapy techniques. While the fracture site will be stiff and sore, you may also lose range of motion at surrounding joints that were moving differently during the healing process. For example, if you have broken your elbow, it is also necessary to  assess your shoulder, wrist and hand to ensure that these joints are moving properly. Not correcting the mobility around the fracture site can prolong your healing process and lead to future injuries as well.

Once your range of motion has been restored, you will need to regain strength in order to return to your pre-injury activities. Your physiotherapist will work with you to create a proper strengthening program to re-introduce your bones to loads and stresses that you encounter in your daily activities. Lack of strength or going back to activity too soon puts you at risk of re-injury or prolonging the healing process. Physiotherapy will help you understand the correct exercises to do and will tailor your program to the activities you plan to return to, whether it be high level sport or recreational activity.

How long until I am back to my regular activities?

Your rehab program will vary in length depending on the type of fracture, if there was surgical intervention, and the type of activity you plan to return to. Depending on the nature of the injury, physiotherapy can take anywhere from 8 weeks to one year for more complex fractures. Your physiotherapist will guide you through your rehab program, ensuring you are progressing at an appropriate rate and prevent complications or future injury.

Frozen Shoulder/Adhesive Capsulitis

By Carla Cranbury, PT

What is it?

Frozen shoulder, also called adhesive capsulitis, is a gradual onset shoulder condition characterized by pain and limited range of motion. This is caused by inflammation and tightening of the shoulder capsule. Typical initial symptoms are pain midway between the shoulder and the elbow and difficulty reaching behind the back. Most women will report that they have difficulty doing up their bra and men difficulty putting on their belt.

Why does it happen?

Limited research has been able to discern one certain cause of frozen shoulder – in short, we don’t know. We do know that it is most common in middle aged women (aged 40-65) and people with diabetes. It also is more likely to occur after a virus, a lingering shoulder injury or after shoulder or upper limb surgery.

How long does it take?

Frozen shoulder goes through three main stages, each of which can take weeks to months:

  • Freezing – pain is noticed and range of motion becomes progressively limited
  • Frozen – pain is reduced, but range of motion is further restricted
  • Thawing – pain is reduced and range of motion gradually returns

Can physio help?

Physiotherapy cannot speed up the course of the condition – everyone has to go through each of the three stages in order to recover. The total process of frozen shoulder can take one to two years to resolve.

What physio can do is help you retain function while going through frozen shoulder, decrease some pain, and ensure a full recovery. Maintaining mobility through the process is important and is where physiotherapy can help the most. Physio will also help prevent other injuries that can be caused by compensating for the frozen shoulder – this is especially significant as it is common for the other shoulder to get the same condition.

Your physiotherapist will give you exercises to maintain as much movement as possible and instruct you on how to perform them properly to ensure you are not compensating for the limited range of motion. Hands on manual therapy will help stretch out the capsule to make the exercises easier to perform. Modalities such as ice, heat, TENS, and acupuncture can also be used to decrease pain.

Though frozen shoulder can be a lengthy and frustrating process, the right care can make it more manageable and prevent any further complications.

Injury Prevention and Physiotherapy

By Cassandra Kroner, PT

best-chicago-group-step-class.jpgIt is a common misconception that you only need to see a physiotherapist if you have an injury or pain. Physiotherapists have a wide range of skills, and recognizing the risk for future injury is one of them. Injury prevention is applicable to all individuals, regardless of their activity level, from the office worker to the athlete, and especially for those with previous injuries that could reoccur.

Repetitive Strain Factors

  • Occupation
  • Training errors
  • Age
  • Excessive or repetitive loads
  • Inappropriate footwear
  • Structural abnormalities
  • Muscle control
  • Core stability
  • Joint alignment
  • Muscle strength and flexibility imbalances
  • Previous injury
  • Posture

In general there are two types of injuries – traumatic and repetitive strain. Traumatic injuries are easier to understand, as they are the result of a singular event that causes damage. On the other hand, repetitive strain injuries occur when stressors that normally do not cause harm are repeated to the point of causing micro trauma that builds over time until the tissue becomes inflamed and injured. These injuries tend to begin subtly, and gradually increase in severity. Combined with the multi-factorial list of possible contributing factors, repetitive strain injuries can be challenging to diagnose and treat. However, in most cases repetitive strain injuries can be avoided with a good injury prevention and maintenance program.

A Common Factor: Muscle Imbalance

When an individual is involved in one specific sport or has a repetitive aspect to their job, the muscles are put under a great deal of strain to repeatedly perform the same movements. Sedentary jobs involving prolonged postures can have similar effects with certain muscles constantly working for long periods. Over time, muscle imbalances develop as the muscles that are being used the most continue to get strong while the reciprocating muscles become lengthened and weak. These muscle imbalances can cause movement restrictions that affect performance and increase stress on the body. Increased stress on muscles, joints and ligaments eventually leads to a repetitive strain injury.

15250-a-young-woman-stretching-outdoors-before-exercising-pv-630x390.jpgThe First Steps Toward Injury Prevention

Getting started on the road to injury prevention is as simple as booking an appointment with a physiotherapist. If you are unsure how injury prevention could apply to you or if you could be at risk for injury, speaking with a physiotherapist can help clarify your needs and goals. The same expert assessment skills physiotherapists use to diagnose injury will be used to proactively assess for risk factors that could lead to future injury. Your lifestyle, the demands of your job, and the specific sports or activities you participate in will be considered, along with the assessment findings, to develop an individualized treatment plan. This plan could involve manual therapy to correct joint restrictions or muscle length imbalance, strength and flexibility exercises, correction of movement patterns, and education.

By addressing several predisposing factors to injury, the body is optimally prepared to handle the demands of the workplace or sport. This can translate to decreased frequency and severity of future injuries, with the added benefit of a shortened recovery time in the event an injury does occur. Don’t wait for an injury to strike to take charge of your health!

The Sitting Solution

Let’s face it, we sit a lot. Between working, commuting, and watching television, the Canada Health Measures Survey found that most Canadian adults spend 9 hours and 48 minutes of their waking time being sedentary. Most of us know that physical activity is good for us, but did you know that just sitting less (regardless of exercise) can also be beneficial in the long term?

A study published in 2009 followed more than 17 000 Canadians for 12 years. Over the twelve years they compared the participants’ daily sitting time and leisure time physical activity with mortality rates of various causes. What they found was that the amount of daily sitting time was positively associated with mortality rates from all causes, except cancer. Basically the more people sit, the higher the risk of mortality. This even includes people who are physically active, showing that high amounts of sitting time cannot be compensated for with exercise, even if it exceeds the current minimum physical activity recommendations.

Other studies have echoed similar findings. A seven year study reported that people who spend less than half their time sitting have a lower risk of mortality than those who spend more than half their day sitting. Another six year study reported that women who spend 16+ hours sitting per day have an elevated risk for cardiovascular disease compared with women who sit for less than 4 hours a day.

These studies are not to say that physical activity is not important – it still is, and it is still beneficial for your health. Physical activity also contributes to decreased time spent sitting.  What these studies are saying is the physiology associated with excessive sitting is different than the physiological benefits of exercise, and therefore excessive sitting cannot be compensated for with periods of exercise.

So now that you know, what can you do?

If you work at a desk most of the day, sitting can be hard to avoid. Some options are:

  • Ask your work if they can accommodate an ergonomically sound standing desk
  • Take frequent breaks from sitting to walk around
  • Go for a walk on your lunch break
  • Walk to your co-workers desk to talk to them instead of sending an email
  • Park at the back of the parking lot to get a few extra steps
  • Take the stairs!
  • Take frequent standing breaks throughout the day
  • Discover new ways to be active during your leisure time – ditch the TV and get outside

It’s the small changes to your daily routine that can add up and make a big difference. The best time to start is today!

Why dancers need the perfect balance of strength and flexibility

By Kelsey Jack, PT

My ballet teacher once told me that given a choice between having strength and flexibility, she would choose strength. This has always stuck with me as there is such an emphasis on flexibility within the dance world that often there is a lack of focus on building the strength required to make use of that flexibility. This enhanced focus on flexibility instead of a balance between strength and flexibility creates muscle imbalances. If dancers work to improve their flexibility and ignore balancing the strength around the joints, it leaves the dancer vulnerable to injury.

Why is balancing strength and flexibility important?

Stability is provided to joints from a combination of passive and active structures. Passive structures include the bones that make up the joint and the ligaments that surround it and support it. Active structures are the muscles and tendons that act to both maintain stability and move the joint. Focusing on passive, static stretching, as is often the case in dance, can lead to instability of joints as the ligaments that are meant to stabilize the joint become stretched out and no longer provide joint support.

Flexibility, or range of motion can be divided into two categories: passive and active. Passive range of motion is demonstrated by how high a dancer is able to lift their leg using their hands whereas active range of motion is how high a dancer is able to lift their leg using their hip muscles and is demonstrated by doing a step like a developpé.  Practically speaking, flexibility without strength limits active range of motion and will hinder the height of legs when performing steps that involve controlled movements and sustained positions.

Back bends are a good example of a movement that is common in dance where strength is required to balance the flexibility of the spine. Dancers without good core strength and control will hinge through their spine, relying on one or two segments to gain all of their movement through. This leaves the spine vulnerable to injury as the ligaments and discs are relied on for support. Ideally when doing a back bend the spine should form a “C” curve. Many teachers instruct dancers to breathe up and extend through the top of their head into their back bend to encourage control into this movement pattern. Engagement of the abdominals and stabilizer muscles of the spine are required to move through each segment of the spine in a way that supports the passive structures of the back to create the desired curve.  It is subtle differences such as these in how a dancer moves, using strength to control their flexibility, that improves the quality of movement and decrease the future risk of injury.

Evidence to support strengthening to increase flexibility

As dancers are often concerned about their hip flexibility, a study was done looking into the best way to increase hip active range of motion. The researchers compared three stretching programs over a six week period. The first group of dancers completed a strengthening program where they worked at strengthening their hip flexors at the end of their available range of motion. The second group completed a “light” stretching program for their gluteals, hamstrings, calves, and quadriceps muscles, holding each stretch for 1 minute. This group was asked to perform stretches at an intensity of 3/10 on a scale where 0 is no stretch and 10 is an intense stretch that elicits a burning sensation. The third group performed the same stretches but at a “moderate-high” intensity which was rated as 8/10 on the same scale. The study found that all three groups had an increase in their passive range of motion but only the strength training and the low intensity stretching groups improved their active range of motion. The strengthening group saw the greatest improvements in both passive and active range of motion which is explained by the hamstrings relaxing as the hip flexor is contracted. This allows the hamstring to lengthen while the hip flexor is strengthened. Intense stretching without strengthening (as in the high intensity group) leads to lengthened, weakened muscles which functionally hinder a dancer’s ability to make use of their range of motion. This study demonstrates that exercises that specifically train the hip flexors progress flexibility in a way that translates into dance.

Strengthening allows dancers to maximize their flexibility without compromising the integrity of their passive support structures and increasing their risk of injury. A physiotherapist can assess a dancer’s strength and flexibility and develop a program that will safely allow a dancer to increase their flexibility while strengthening the muscles needed to support their joints, improve performance, and decrease risk of future injury.
