The key is for the practitioner to employ physiotherapy techniques and education to help the person to use their body better and function better overall. The idea of the Alexander Technique is to provide a physiotherapy that will allow muscles to become relaxed. This is said to give people back the posture they should have had all along. After an initial evaluation, they will be scheduled for treatments like ultrasound or acupuncture. They will be assigned exercises to do at home. A good physiotherapist will begin treatment right away. People, who ask what is physiotherapy, often do not consider the preventative side of the field. It is a part of the work of practitioners of physiotherapy to encourage exercises and postures that will help patients avoid physical injuries and conditions requiring their services. After the initial period of the monitored physiotherapy has passed, cardiac surgery patients will be sent to do their exercising at home. Before they go, though, they will have been taught warm-up and stretching exercises, and when to stop. Generally, they should exercise three to five times a week unless they are having problems. By doing so, one could learn to evaluate physical problems, create plans for patients, and see to carrying out those plans. A physiotherapy career can be professionally rewarding. The average physiotherapist is between 25 and 54, earns $50,000 to $60,000, and works in a full-time salaried position. Many of these started out with a BA degree, but the trend is towards hiring MA degree or doctoral degree holders who are beginning a physiotherapy career. The physiotherapist will give exercises where the patient lies on the side, back, or stomach and works out or sits up and works out. There are many restorative therapies in physiotherapy for spinal cord injury patients. These include electrical stimulation, biofeedback, vibrational therapy, laser therapy and other stimulation activities. The patient will probably need help during amputee rehabilitation to learn balance all over again. This is especially true is the affected limb is a foot or leg. However, having an arm that is of a different weight than the other may be unbalancing as well. Physiotherapy can help with these problems too.
