(RSI : repetitive stress injuries, CTS : carpal tunnel syndrome.)
However, there are conditions that can precede the onset of CTS, and these can also produce symptoms of pain and numbness. Usually these are caused by prolonged muscle tension, which results in restriction of blood flow. When blood flow is restricted, not only do muscles and nerves not receive nourishment that they need for repair, but the removal of metabolites from normal muscle functioning is also restricted. Edema of surrounding tissues can result, which increases pressure and tension in the area. Many RSI problems occur in a cycle of tension, restriction of blood flow, edema, and consequent further restriction of movement, that eventually leads to severe problems. Muscle-tension producing RSI problems may be due to repetitive movement, or may be a somato-emotional event that results from psychological stress. In my experience, bodywork of any kind is of minimal help in directly reducing symptoms once the nerve has been injured and full-blown CTS has developed. However, in the long cycle of micro-injury that produces symptoms of RSI, bodywork can be of great help in reducing tension and edema, increasing blood flow, and encouraging different movement that may reduce or reverse RSI symptoms.
