Abstract: A method of limiting arm movement using a reversible arm movement limiter having a first curvate brace section joined to a second curvate brace section. A removably attachable fastener for securing the curvate section to a user is provided as well. In a preferred embodiment, the first currate brace section is shorter in longitudinal length than the second, longer, curvate brace section and the removably attachable fastener is attached to the longer section. Both curvate brace sections are curved so as to more nearly conform to the form of a user's upper and lower arm. The fastener of a preferred embodiment includes at least one stretchable elastic band with two ends. The first end is attached to the longer curvate brace section at one end. A free end is free to stretch around the user's arm. To secure it in place, the invention incorporates the use of hook and loop material so that the free end is removably attachable and infinitely adjustable.
