Some of them are heat, acupuncture, ultrasound, and electrical stimulation. There is a need for physiotherapy in amputee rehabilitation that no other discipline can fill. It is a basic kind of help that anyone who has lost a limb can use. Some amputees decline treatment because they do not think it is necessary. This is done by cupping the hand and clapping the back to loosen secretions in the chest. It is also called chest percussion. The physiotherapist will do this procedure, and will teach it to a family member or caregiver. People with chronic airways disease often have a problem with weakening legs. This is because, as they have trouble breathing, they avoid walking or doing physical exercise of any sort. Patients who have other cardiac problems can use the help too; they include victims of heart attacks, heart failure, peripheral artery disease, chest pain, and cardiomyopathy. Physiotherapy will usually begin within a couple of weeks of cardiac surgery, if not sooner. The first step is for nurses or doctors to administer a stress test to determine how much exercise one can handle. The types of problems faced in geriatric physiotherapy are grouped into three different categories. 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. 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. Physiotherapists can step in and help the patients recover their strength and health. Physiotherapy techniques may include exercises, massage, and ultrasound. A physiotherapist will certainly give instructions about how to do home treatment. When the occupational injury is sufficiently healed, the patient will be given the go-ahead to return to work.
