Exercise Reduces Neuropathic Pain

The June issue of Anesthesia & Analgesia has an animal study that shows that exercise can reduce neuropathic pain. The study was performed on rats that were given an injury to their sciatic nerve.  A group was then progressively trained to either swam or run on the treadmill. Compared with non-exercising rats, the exercising rats experienced less pain. Exercise also reduced the expression of inflammation-promoting cytokines in the sciatic nerve tissue. Other studies have shown that inflammatory cytokines contribute to pain. For years exercise has been recommended for people with chronic pain. This was the first study that looked at neuropathic pain.
