An orthosis for passive and active movement of a joint of a body limb, permitting application of adjustable flexion or extension bias to that limb without the application of direct force on the joint. A spaced pair of proximal and distal shafts for medial and lateral positioning about the joint and proximal and distal parts of the limb are provided, these cooperating proximal and distal shafts being joined at a pivot. The pivots are juxtaposed the joint and permit pivoting the distal shafts in a direction corresponding to the direction of movement of the distal part of the limb. Cuff and strap means are secured between opposite proximal and opposite distal shafts to releasably secure the orthosis to proximal and distal parts of the limb. Securing means are associated with portions of the proximal and distal shafts at positions spaced from the pivots. Linear biasing means, such as elastic bands or springs, are releasably secured by these securing means to join proximal and distal shafts, the securing means being so positioned, with respect to the shafts, that the linear biasing means are capable of being secured thereto to exert either flexion or extension bias on the proximal shafts.
