It is very common for people to ask can pilates help with osteoporosis? This is because osteoporosis treatment with exercise is a mantra of doctors, physiotherapists and rehabilitation practitioners worldwide, however it can be a little overwhelming to understand what this actually means. How does this translate into reality for many people? What is proven to be effective and what is actually a fad?
In this article, we explore osteoporosis and how it is diagnosed, how it is characterised, and the guidelines as to what is appropriate for treatment. Some of the information we have gathered for this article has come from trainings with Louise Drysdale (physiotherapist for the Queensland Ballet and PhD candidate); Monique Kurki (musculoskeletal physiotherapist and certified Pilates instructor with a special interest in this area), as well as from our own literature reviews conducted for our training courses for movement professionals. The purpose of this article is to increase understanding of what to do and how to work with people once they are diagnosed with osteoporosis or osteopenia. However, it is not about the prevention of osteoporosis.
What is osteoporosis?
Osteoporosis is a disease characterised by low bone mass and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. However, for epidemiological and clinical purposes, osteoporosis (for post-menopausal women only) is defined by a Bone Mineral Density test result (generally of hip and spine). When a person is given their test result they will see a T score and a Z score. The T score shows how much the persons bone mineral density is diverging from the average health thirty year old adult. A T score of – 2.5 is considered to show osteoporosis. A score between -1 and -2.5 is considered osteopenia. A person will also be given a Z score which compares their score to what would be expected of someone of equivalent age, gender and race. These measures are then used to identify if a person is at risk of bone fractures.
Osteopenia is the term used by doctors to describe low bone density. People with osteopenia have bones that are weaker than normal, but not weak enough to be called osteoporosis. Nguyen et al (1993) stated “Bone mass, assessed by Bone Mineral Density (BMD), is a good predictor of fracture risk, with each standard deviation (SD) decrease in BMD being associated with at least a twofold increase in the risk of fracture”7.
Who is affected by osteoporosis?
In Australia:
// One in two women over the age of 50 and one in four men have low bone density with a prediction of fracture in their lifetime.
// More than 50% of women and 70% of men who sustain a low trauma fragility fracture (eg. fall from a standing height) have a diagnosis of osteopenia rather than osteoporosis.
In other words, its prevalence is such that there is a high likelihood that you will see someone who has either been diagnosed with or is at risk of having osteopenia or osteoporosis.
Overall fracture risk from osteoporosis
Fracture risk however, is a function of BOTH trauma sustained (eg. falls) and bone strength (which in turn depends on both the quantity of bone (mass) and its architecture). Half of all falls occur around the home and approximately one third of people over 65 will have a fall each year. It is estimated around 6% of falls result in a fracture, so preventing falls has become an important part of managing bone health and osteoporosis treatment.
Falls are most commonly caused by:
// Poor muscle strength, especially of legs (and also poor flexibility)
// Problems with balance due to weak muscles, slow reflexes, low blood pressure, inner ear problems, some medicines, poor nutrition and sometimes also feet and shoe issues
// Poor vision
// Home hazards that cause tripping
Physiology of bone and bone mineral density
Bone is constantly remodelling; microscopic amounts of bone tissue in the skeleton are removed by osteoclasts (bone resorption) and then replaced with new tissue by osteoblasts (bone formation). In the first year of life, almost 100% of the skeleton is replaced, whilst in adults, remodelling proceeds at about 10% per year. Remodelling occurs following injuries like fractures, but also occurs in response to the functional demands of mechanical loading.
Bone mineral density is reduced when the rate of bone resorption is greater than the rate of bone formation, resulting in a net bone loss of both trabecular and cortical bone. Many factors can contribute to bone resorption outpacing bone formation.
Osteoporosis and osteopenia can be found in the younger population (ie under 65)
Whilst age is a significant factor in the existence of osteoporosis, there are some people that can be susceptible to early onset osteoporosis. Those people include:
// Those who have been using steroids for more than 5 years – think of asthmatics or people with chronic illness like multiple sclerosis
// Cancer patients who have been through chemotherapy
// Women who have had early onset menopause
// People who have had any one of a number of autoimmune diseases that can affect the absorption of vitamin D or nutrients
Don’t always assume that your younger clients will not be at risk of osteoporosis and therefore won’t require osteoporosis treatment. Rather, make sure that you do a thorough screening and questionnaire with them to ensure that you are able to adequately determine if there is the potential for risk. In those cases I always suggest that they consult their doctor for testing.
The Australian College of General Practitioners, has a screening list for risk factors and referrals for clients particularly those over 50 years of age, see image below. You can see that the GP protocols are really about identifying who maybe at risk and identifying falls risk. Falls risk is important because if a person does have osteoporosis does have a fall, they are likely to break a bone commonly their hip bone. When an older person does have a fracture they are at higher risk of other health complications because of the need to attend a hospital and have surgery.
What about Fractures?
There are many types of fractures and it takes time for a person to recover from a fracture. The period of immobility from a fracture can be problematic. It is important for people who have had a fracture to understand the healing process and the importance of allowing yourself to heal.
What about exercise?
In the UK a consensus report was recently published explaining ideas and options about exercise in relation to low bone density (Brooke-Wavell K, Skelton DA, Barker KL, et al, 2021). The recommendations made reference to standards and concepts also considered in Australia. The report highlighted the three important criteria for protection from fractures and to maximize bone strength. Those recommendations are listed below, and it was interesting to see that the report recommended Pilates for all three of its categories of exercise (see Diagram below);
(1) resistance and impact exercise to maximise bone strength;
(2) activities to improve strength and balance to reduce falls;
(3) spinal extension exercise to improve posture and potentially reduce risk of falls and vertebral fractures. (For safety, we recommend avoiding postures involving a high degree of spinal flexion during exercise or daily life.)
Osteoporosis treatment and exercise – how can Pilates help?
In Australia many of the guidelines on working with people with osteoporosis are detailed in the 2017 Beck BR, et al. Exercise and Sports Science Australia (ESSA) position statement on exercise prescription for the prevention and management of osteoporosis. J Sci Med Sport (2016), http://dx.doi.org/10.1016/j.jsams.2016.10.001. Those guidelines give details about:
// Balance
// Joint mobility
// Load or resistance levels
and what are the appropriate testing and levels for those people with osteoporosis and osteopenia at different risk levels, categorised from low risk to high risk.
Balance for osteoporosis treatment in a Pilates studio setting
Specific balance work should include focus on challenging all parts of the balance system, namely proprioceptive, vestibular and visual. To be honest this should be part of any movement class regardless of the person’s age or bone health. Maintaining good balance and fall prevention is an essential part of a functional life. Accordingly, a good movement class will incorporate various techniques to challenge the balance systems and build reaction times in order to help people recover from a fall. There has been research coming out of the University of Queensland’s Physiotherapy Department about how balance starts to decline in women in their 40’s. To learn more about balance and strategies to work with clients, you can do our Chucking a Wobbly online course. Some ideas for working with balance in a Pilates class are included in this little zoom class I taught a few years ago. If you are wanting to learn more about balance you can book in for our live, online or zoom sessions by contacting us.
Use the CoreAlign for some standing work eg this Flow Class from the Pilates Stands Up Bundle
Working on maintaining dorsiflexion in the feet and hips mobility is another great way to improve someone’s balance and gait which can reduce falls risk. Below is an example of how you can use the Makarlu as a way to help improve dorsiflexion in the ankles.
