Chiropractic doctors practice physiotherapy techniques to put the body back into alignment after postural problems occur. They can do manipulations to help the patient regain full range of motion. They can also work on the muscles to ease tension there. Postural problems are common for people of all ages. College coursework beyond the bachelor's degree is required for good physiotherapy credentials. If a physiotherapy candidate meets all the requirements, a master's degree with advanced training will prepare her for work in the field. Physiotherapy credentials to look for are: Foreign Credentialing Commission on Physical Therapy (FCCPT), International Education Consultants (IEC), International Consultants of Delaware, Inc. 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. 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. If left to their own devices, they will cripple the limb further by letting it atrophy through nonuse. Physiotherapy can provide such a program during amputee rehabilitation. This will take into account the different movements needed by amputees to perform normal exercises. Manual therapies, such as massage, are a part of amputee rehabilitation with physiotherapy. This can relieve much pain and tension in the muscles that are overworked in getting used to their new situation. At other places, one simply takes about three years of school after the bachelor's degree. Doctoral degrees have similar requirements. Before one gets into a physiotherapy degree program, one needs to meet specific requirements. Coursework in various life sciences like biology, anatomy are needed. Also important are courses in fields like psychology and social science.
