An elongated rigid legboard is secured to the back of the leg of a patient suffering from a contracture of the heel cord and/or its associated muscles. Straps connected to the legboard hold the knee joint in fully extended position. A footboard pivotally mounted on the legboard is swung upward to engage against the underside of the patient\s foot and apply a force tending to swing the foot upward, which thereby applies stretching force to the heel cord to treat the contracture. A ratchet permits upward swinging movement of the footboard relative to the legboard as the force is applied but prevents downward swinging movement of the footboard relative to the legboard when the force is removed so that static tension force continues to be applied to the heel cord.

A therapeutic heel cord stretching appliance for a patient comprising an elongated legboard of substantially rigid material, legboard securing means for firmly securing said legboard to the patient\s leg in substantially straight condition, an elongated footboard pivotally connected to one end portion of said legboard and engageable with the underside of the patient\s foot, an elongated force-transmitting member connected to the swinging end portion of said footboard and of a length to enable the patient to grasp and pull on said force-transmitting member when his leg is thus secured in straight condition, and locking means connected between said legboard and said footboard enabling swinging of said footboard relative to said legboard in one direction to progressively advanced positions to decrease the included angle between said boards so as to apply inceased stretching force to the heel cord and for automatically preventing in each progressively advanced position of said footboard appreciable inadvertent retrograde swinging movement of said footboard relative to said legboard in the opposite direction to increase the included angle between said boards and decrease the stretching force applied to the heel cord without requiring the patient to release his grasp on said force-transmitting member and manipulate said locking means.
