Physiotherapists can be very helpful in preventing occupational injury in any other type of workplace. They may be called in to consult with employers and ergonomics specialists about what changes need to be made to make the work environment acceptable for their patients. Work environments are safer than they once were. Another of the sports injuries that physiotherapy is used for is tennis elbow. One might get tennis elbow from playing tennis, certainly, but it can also come about from any activity that involves twisting the wrist. Sports injuries like tennis elbow are treated with a comprehensive plan of physiotherapy. 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. Physiotherapists use stroke rehabilitation to make sure that patients do indeed work to use their impaired limbs. They can do this in a number of ways. Sometimes it helps for the physiotherapist to tap or stroke the limb they want the patient to use. 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. Yet, the reality must be faced that pediatric disorders can happen. The good news is that physiotherapy offers some help for them. Unfortunately, there are numerous pediatric disorders. To name a few, there are: scoliosis, torticollis, Osgood-Schlatter, sports and traumatic injuries, reluctant walkers, developmental disorders, cerebral palsy, and genetic disorders. This will be an ongoing therapy that will require dedication over the rest of the patient's life. However, it is common that the exercises and other therapies help the rheumatoid arthritis so much that the patient will have incentive to keep doing them. A physiotherapist understands how all the parts of one's body work together to create movement.
