ABSTRACT:
A range-of-motion splint for applying relatively constant torque across a joint undergoing rehabilitative therapy. The splint includes a first brace section configured to engage a portion of a patient's body on a first side of a joint, and a second brace section configured to engage a portion of the body on a second side of the joint. A first arm extends from the first brace section and a second arm extends from the second brace section. The first and second arms are connected by a dual axis pivot mechanism for rotational motion about both a primary joint axis and a lateral axis generally perpendicular to the primary joint axis. A first spring-engaging mount is located on the first arm at a position spaced from the primary joint axis. A second spring-engaging mount is located on the second arm at a position spaced from the primary joint axis. An eccentrically mounted spiral spring has an inner end mounted to the first spring-engaging mount, and an outer end mounted to the second spring-engaging mount. The amount of torque between the brace sections can be adjusted by a torque adjusting mechanism which winds and unwinds the spring. An adjustable stop mechanism can be used to limit the range of rotational motion between the brace sections. The brace sections can be locked with respect to one another by a locking mechanism which engages and prevents movement of the brace sections.
