Parkinson's: A progressive disease
Parkinson’s patients start out just as physically fit as anyone else. As the disease progresses, however, they will gradually lose their range of motion, particularly in their back and neck. In addition, tremors, freezing, slowness, changes in balance and a decrease in muscular strength will make it difficult to maintain as active a lifestyle as they once had. Most people never think of how much they use the muscles. Everything that is done requires the use of the muscles, from speaking to simply sitting and stretching your legs. The body is made up three different types of muscle: smooth muscle, cardiac muscle and skeletal muscle.
