If a child has repeatedly sprained the same ankle, therapy will necessarily focus on that ankle, as well as any body part that supports or counterbalances that ankle. Overall strength is important. Traumatic injuries require a certain amount of psychological training, as the subject of the accident or other ordeal may bring on such distress that the child does not want to work. When the occupational injury is sufficiently healed, the patient will be given the go-ahead to return to work. If the patient was on light duty, he will be told when to go back to regular duty. If he was off work, he will be told when he can go onto light duty, and then the full daily routine. Physiotherapy ideas can also be used to construct a better work environment. It is also important to be aware of the degrees that are available to earn, and the length of the course of study. The final step before getting that first job to start a physiotherapy career is accreditation. The Commission on Accreditation in Physical Therapy Education (CAPTE) is tasked with ensuring that physiotherapists are fit for the licensing exam. It can refer to any normal position that the body usually holds. When the shoulders are hunched forward or the arm is extended in an awkward position, these are postural problems. They can lead to muscle and joint pain, headaches, and other unpleasant symptoms. Some postural problems are caused because a person has pain in one part of her body. 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. Another category geriatric physiotherapy deals with is cardiovascular disease, like heart disease and stroke. 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. If left to their own devices, they will cripple the limb further by letting it atrophy through nonuse. Physiotherapists use stroke rehabilitation to make sure that patients do indeed work to use their impaired limbs.
