Osteoporosis 6 – Precautions to Keep in Mind When Exercising
There are many factors that are often overlooked when developing an exercise plan, yet they are no less important. These include (Moreira et al., 2017):
- Wearing tight fitting shoes.
- Wearing shoes with a grippy sole.
- Warming up prior to exercise.
- Maintaining the correct posture during each exercise to prevent fracture and muscle strain.
- If undertaking exercises that improve proprioception (such as a wobble board) the patient should stand next to a wall to prevent a fall.
As abdominal muscles are used in the maintenance of good posture, daily activities and normal spine function, it is important to keep them well toned. One of the main actions of the abdominal muscles is spinal flexion, however this presents a problem. Nachemson (2006) found that spinal flexion exercises creates the most loading through the vertebral bodies of all the body positions. Sinaki and Mikkelsen (1984) found that, when assessing a group of osteoporotic women, after 2 years of performing spinal flexion exercises, 89% of them presented with vertebral fractures. Useful alternative exercises are as follows (Moreira et al., 2017):
- Isometric contractions with a physiological alignment of the spine (without a Valsalva manoeuvre).
- Hip flexion in a supine position.
- Hip anteversion and retroversion.
- Forced exhalation.
Another precaution is to avoid placing 100% trust in the results of a DEXA scan. The effects of corticosteroids must be considered here. Whilst the results of a DEXA scan may show normal values for a person’s bone mass, the bones may still be of poor quality and fragile (Buehring et al., 2013). Fractures in those using oral corticosteroids occur at a higher rate than those with involuntary osteoporosis (Van Staa et al., 2007). Therefore it is important to consider other factors when considering a person’s bone health such as (Taylor., 2004):
- Previous fracture rate and cause
- Calcium intake
- Vitamin D intake
- Alcohol consumption
- Cigarette use
- Corticosteroids use
