The Merry Therapeutic Walker is a self-rehabilitation walker designed to increase muscle strength, address balance concerns, and provide security as patients relearn to walk. Like most standard walker models, the Merry Therapeutic Walker features a similar design that includes non-skid rubber tips, and height adjustable legs. However, it is heavier than other standard walkers. The walker itself weighs six pounds and also includes eight one-half pound weights that can be placed inside the legs. This produces muscle flexion which helps users rebuild back, leg and arm muscles as they rehab.
