Clinical massages have very specific therapeutic benefits. For example, the injured parts of accident victims are massaged to aid their rehabilitation. And it is quite common to massage affected areas following surgery, if it is appropriate. Health insurance companies will pay for massage, and some employers will encourage their staff to visit spas in order to prevent physical damage that might be caused by unhealthy movements or postures in the workplace. Reflexology aims to stimulate individual organs or particular areas of the body. The field of clinical massage is vast, and distinguishing it from non-clinical forms of massage appears to be all the more important, despite the fact that the boundaries between the two are fluid and a strict distinction is quite impossible.
