Physical medicine and rehabilitation uses a range of physical techniques such as heat and electrotherapy, as well as therapeutic exercises and behavioral therapy. These techniques are usually part of an interdisciplinary or multidisciplinary program that might also include pharmaceutical medicines. Spa therapy has showed positive effects in reducing pain among patients with chronic low back pain. However there are limited studies looking at this approach. Studies have shown that kinesiotape could be used on individuals with chronic low back pain to reduce pain. The Center for Disease Control recommends that physical therapy and exercise can be prescribed as a positive alternative to opioids for decreasing one's pain in multiple injuries, illnesses, or diseases. This can include chronic low back pain, osteoarthritis of the hip and knee, or fibromyalgia. Exercise alone or with other rehabilitation disciplines (such as psychologically based approaches) can have a positive effect on reducing pain. In addition to improving pain, exercise also can improve one's well-being and general health.
