This includes strength training, training in the use of supportive devices, and help with common tasks. One problem physiotherapists face when working with MG patients is that too much exercise will make their condition worse and not better. Many of the patients with neurological conditions cannot carry on daily functions such as caring for themselves and their homes. Physiotherapy personnel are challenged to keep the child's spirits up as they teach them how to exercise with and without special equipment. Brain injuries, including cerebral palsy and strokes are pediatric disorders that must be managed delicately. The neurological system is often not as sturdy as the skeletal or muscular systems. They can be used separately, or they can be used alternately by a person who is suffering from acute lower back pain. A transcutaneous electrical nerve stimulator (TENS) can be used as another modality for lower back pain. The patient will feel the sensation of the stimulator instead of his pain. If the TENS unit seems to work well for him, he will be sent home with one to use at his convenience. Physiotherapy credentials to look for are: Foreign Credentialing Commission on Physical Therapy (FCCPT), International Education Consultants (IEC), International Consultants of Delaware, Inc. (ICD), International Education Research Foundation (IERF), and International Credentialing Associates, Inc. (ICA). When the data is gathered and analyzed, a program of physical therapy will be put into place. For safety's sake, it is often the routine to bring cardiac surgery patients into the hospital or an outpatient clinic for their exercise at first. Under the watchful eyes of nurses and physiotherapy personnel, cardiac surgery patients will be looked after as they perform their exercises. Alzheimer's, arthritis, balance disorders, cancer, cardiovascular disease, incontinence, joint replacement, pulmonary disease, stroke, and osteoporosis are only a few of the problems covered by geriatric physiotherapy. Physiotherapists have a whole range of therapies for these ailments. The types of problems faced in geriatric physiotherapy are grouped into three different categories.
