Why does balance become more of a problem with age?

As we get older, we stop exploring our environments the way we did as kids. For instance, we don’t do headstands or ride on swings. But those are activities that force the brain to integrate various kinds of information; so, when kids stumble, it’s easy for them to regain their balance. However, when an adult trips, the influx of information can overload the brain and the adult loses balance.

Does this mean the difficulty of recovering from a stumble isn’t necessarily a mechanical problem?

It isn’t. It happens because the brain hasn’t incorporated information fast enough to respond appropriately.

How can physiotherapy help improve balance and mobility in Parkinson’s?

People with Parkinson’s and other neurological conditions causing weakness or postural changes are often forced to move in limited ways. Once that happens, it becomes hard for them to explore other types of movements and, if left on their own, many never will. A physiotherapist can recommend exercises that force the body and brain to experience different scenarios that people would never put themselves into. The physiotherapist can also help people retrain their brains to respond more quickly when their balance is disturbed.

How does this balance retraining work?

Balance is a beautiful relationship between
• the visual system, which takes in information through the eyes;
• the proprioceptive system, which takes information from the receptors in your joints and tells your brain if you’re in alignment or out of alignment; and
• the vestibular system, which is located in the inner ear and takes into account head and eye position.

Because vision usually takes precedence, most people have underused one or both of the other systems. However, if you can improve the use of the idle systems, you can achieve some good results.

Try this simple exercise. Stand in front of a counter, rest your hands lightly on the counter and close your eyes. How do you stay on your feet and not wobble? Well, your proprioceptive system kicks in. If you’re out of alignment, it signals the brain which then alerts the muscles to pull you back into alignment. Your vision isn’t doing its usual bossy job, so these other systems have to pick up the slack.

When people with Parkinson’s do this type of exercise regularly, then, the next time they encounter a slight disturbance in their balance or get nudged or trip on the curb, their proprioceptor-brain-muscle pathways are likely to respond sooner because people have had practice integrating the different strands of information.

How does physiotherapy help with posture?

Over time, many people with Parkinson’s develop a stooped posture where their centre of gravity falls in front of the body rather than over the feet. A good physiotherapy routine will include both exercises to strengthen the muscles along the back and counterbalance the tendency to be pulled forward, and exercises to stretch the muscles along the front of the body which tend to contract when a person becomes stooped.

How much exercise is enough?

Set realistic goals. A consistent 20 minutes of exercise a day is worth more than an occasional 45-minute spurt. In fact, exercise should be seen as a Parkinson’s disease management strategy. It can make a big improvement to quality of life, balance and walking; but if you don’t keep it up, you lose all the benefits. Some of my clients say that exercise empowers them with some sense of control over their disease.

What should a person with Parkinson’s look for in a physiotherapist?

If looking for a physiotherapist, ask the clinic how skilled or experienced the physiotherapist is with Parkinson’s disease.
