According to worldwide statistics, one in eight hundred people suffers from Parkinson’s disease. Based on this calculation, there are approximately eight thousand patients in Hong Kong. As the population ages, there will be more than 10,000 Parkinson's disease patients in Hong Kong. Elderly people aged 60 or above have a higher prevalence rate of 1%; about 10% of the patients have the disease before the age of 40. Most Parkinson's disease is primary (that is, the cause is unknown). Parkinson’s disease is a chronic brain degeneration disease. It is caused by the rapid degeneration of the part of the brain called "substantia nigra" that fails to produce enough "dopamine", which affects muscle activity and greatly hinders the patient's ability to move.

Studies have shown that high-intensity exercise can help slow the progression of early Parkinson's disease. Exercise helps preventing other complications caused by stiffness, which is very important for patients.

For patients with Parkinson’s disease, apart from the fact that their mobility will be weakened and walking will be difficult, the resting muscle tone will sometimes be higher, and the soft tissues will tend to become tightened. Stretching is indeed essential. Together with other regimes such as cardiopulmonary function/balance training and medical treatment, some clients can still maintain good walking ability even in 5 years of time after diagnosis.
