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. During stroke rehabilitation, it will be determined whether these limbs will reach their previous potential. If not, the physiotherapist will teach the patients ways to manage without their full use of the limbs. One problem of stroke rehabilitation is called learned nonuse. This is when stroke patients do everything in their power to avoid using limbs that have been affected by the stroke. Lower back pain exercises called flexion exercises strengthen the midsection to provide support for the back. If the lower back pain is reduced when one sits, these exercises are important. One is a knee-to-chest exercise. Aerobic exercise such as walking is excellent for reducing and preventing lower back pain as well. Workman's comp will probably take care of treatment if the occupational injury is more than a slight one. Carpal tunnel syndrome is often seen in offices. However, it may also occur in other jobs, such as on assembly lines. Tennis elbow can be an occupational injury as well, occurring any time one repetitively twists one's wrists. The neurological system is often not as sturdy as the skeletal or muscular systems. However, brain injuries also involve these other systems as well. A new treatment for these pediatric disorders like brain injuries is using hyperbaric oxygen therapy. This type of physiotherapy is based on the idea that, in these conditions, there are often parts of the brain that are not working but can be revived. Then, exercises can correct the neck, shoulder, and wrist problems that have resulted from postural problems. Surgeries, like the Carpal tunnel surgery, are the last resort, as physiotherapy can take care of most of these postural problems before such drastic measures are needed. If one wants to avoid surgery, getting physiotherapy early on is a key.
