A massage done by an untrained person may do more harm than good. These methods are called passive therapies, or modalities. They are done to the patient and not by the patient. There are other modalities that are commonly used. Heat and ice packs are a well-known form of passive physiotherapy. They can be used separately, or they can be used alternately by a person who is suffering from acute lower back pain. These are questions to answer before going to the clinic for help. The simple answer is that no one can pinpoint the exact amount of treatment a person will need, so overall physiotherapy costs are just an estimate. It is possible for an experienced and skilled physiotherapist to make a fairly accurate approximation of how long treatment will take. If this is not possible, the goal is for the patient to reach a goal that is the best movement and lack of pain that is possible. People who are referred to a clinic may ask, what is physiotherapy? However, they will be given quick answers to this question. After an initial evaluation, they will be scheduled for treatments like ultrasound or acupuncture. The physiotherapist will instruct the patient about what activities are acceptable in the weeks and months after surgery. During the first six weeks, there will only be a few activities allowed, such as light housekeeping or going to movies, for example. From then until the third month, more activities will be added. 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. Physiotherapists use stroke rehabilitation to make sure that patients do indeed work to use their impaired limbs. It is taught to people who are young and people who are old. It is taught to anyone comes to be taught. Alexander Technique practitioners usually work with people on an individual basis. Groups can sometimes be taught the Alexander Technique, but this is not standard practice. 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.
