A physiotherapist will teach a patient how to care for their injuries. He will teach exercises to do at home so that therapy can continue beyond the walls of the clinic or hospital. He will teach ways to overcome difficulties that cannot be cured. Another part of what is physiotherapy is rehabilitation. Yet, that is just what is recommended. Types of cardiac surgery include bypass surgeries, angioplasty, stents, heart valve replacements, and even heart transplants. Patients having all of these surgeries can benefit from physiotherapy. Patients who have other cardiac problems can use the help too; they include victims of heart attacks, heart failure, peripheral artery disease, chest pain, and cardiomyopathy. These mats are raised off the floor, and can be operated by a hand crank or a power system. The physiotherapist will give exercises where the patient lies on the side, back, or stomach and works out or sits up and works out. There are many restorative therapies in physiotherapy for spinal cord injury patients. It will include ways to prevent rheumatoid arthritis from disabling one. As time goes by, the focus will shift to a more here and now sort of treatment. Exercises will be geared more towards current problems. Water exercises can be used for people with rheumatoid arthritis. These exercises allow the person to get much needed strengthening and stretching exercises done. It is not an automatic thing to get used to a prosthetic limb. Many patients have them for years without ever having normal functioning with them. This is one reason amputee rehabilitation is so important. Physiotherapy can benefit amputee rehabilitation by gradually getting the patient accustomed to using a prosthetic limb. The types of problems faced in geriatric physiotherapy are grouped into three different categories. One category is the problems that happen because the patient simply does not use their limbs or does not exercise. These problems can be addressed by reconditioning through range-of-motion exercises and other exercises.
