It strengthens the muscles, increases oxygen to the muscles, and helps you lose weight. Aerobic exercises you can do include walking, running, swimming, or bicycling. Any exercise that gets you breathing heavily and your heart rate up will do. In injuries like low back pain, weight loss can be a factor. Geriatric physiotherapy helps people who have these disorders, such as osteoporosis and osteoarthritis. These problems require special attention as osteoporosis makes patients frailer, and osteoarthritis is very painful. Because falls are such a problem, the osteoporosis therapy is crucial. Along with that, geriatric physiotherapy is responsible for preventing many falls because of work with balance and gait. They can be life-threatening at times, and they can certainly affect the quality of the patient's life. There are many neurological conditions and physiotherapy can help many of them. Alzheimer's disease takes away the declining years of many older people. It is surprising to note that it can occur in people 40 years old or younger. Another method used by physiotherapists for those with chronic airways disease is called clapping and postural drainage. The postural drainage part is done by positioning the body so that the affected lung is above the trachea. Many people do this at home by lying on a bed and bending the top half of the body over it. Another part of what is physiotherapy is rehabilitation. Patients have injuries from sports, car accidents, or assault. These injuries can be treated through physiotherapy. Given the right treatments and an injury that will respond to treatment, much progress can be made. Full functioning may be regained. If a physiotherapy program is not followed faithfully, the spine will begin to atrophy below the level of the spinal cord injury. The spine will shrink and the whole body below that point will become weaker as time goes by. It is important that spinal cord injury patients get exercise of some form. They are prone to osteoporosis and heart problems, among other conditions.
