At other places, one simply takes about three years of school after the bachelor's degree. Doctoral degrees have similar requirements. Before one gets into a physiotherapy degree program, one needs to meet specific requirements. Coursework in various life sciences like biology, anatomy are needed. Also important are courses in fields like psychology and social science. It is necessary to stretch the shortened muscles before trying to strengthen, or tighten, the longer muscles. Physiotherapy exercises have been invented for just this purpose. Anyone who works with a mouse that is not close enough to their keyboard is prone to postural problems. The first step is to make a better arrangement of the work space. Sports injuries like tennis elbow are treated with a comprehensive plan of physiotherapy. Exercises are explained and assigned. Another common procedure for sports injuries is the use of ultrasound. Ultrasound is a way of applying heat deep into the muscle for pain relief. Electrical stimulation can be used to keep pain from being felt through the nervous system. The physiotherapy professional has an array of tools at her disposal to work with these conditions. Exercise, aqua therapy, electrical stimulation, and more can be used. The third category is skeletal problems. Geriatric physiotherapy helps people who have these disorders, such as osteoporosis and osteoarthritis. If the patient will not easily participate in active range of motion exercises, passive ones can be used where the physiotherapist moves the limb herself. Other times, the patient will try to use the affected limb but will naturally fall back on the limb that is functioning well. In this case, stroke rehabilitation may involve gently restraining the healthy limbs. The physiotherapy assessment will begin when the therapist takes a medical history. This is standard procedure for any type of health related problem. It is wise to be thorough in explaining past problems and conditions that seem to run in the family. This can have a bearing on your treatment. It might even point to some disease or disorder that no one suspected that you had.
