Abstract: An arm therapy device for the prevention and treatment of repetitive stress injuries of the elbow, forearm, and wrist. The arm therapy device generally includes a housing adapted to be freestanding in an upright manner. The housing includes an upper opening which provides access to the interior of the housing. Rollers across the interior of the housing comprising pairs of rollers which are biased inwardly toward each other. Bias members such as resistance bands may be utilized to bias each pair of rollers toward each other. Collars may be utilized on the rollers to which the bias members are connected. By using the present invention, one may treat a limb such as an arm without having to support the housing with another hand or another person. As the limb passes through the housing, the rollers will exert pressure on the limb which aids in treating or preventing repetitive stress injuries.
