Abstract: Devices and methods for preventing knee sprain injuries. To protect the knee joint from knee sprain injuries, the device comprises a sensing part configured to sense data associated with knee motion; an analyzing part configured to analyze the knee motion data to determine a knee articulation; and a stimulating part configured to stimulate one or more lower limb muscles to initiate an earlier muscle reaction than would naturally occur in response to the determined knee joint articulation. The determined knee joint articulation may include knee joint articulation or a particular type of articulation such as a knee sprain movement associated with knee sprain. The methods involve sensing data associated with knee joint motion, analyzing the data to determine a knee joint articulation; and stimulating one or more lower limb muscles to initiate an early muscle reaction within the determined knee joint articulation.

Abstract: A device and method for measuring joint rotation of an object, which provides an objective quantification of a laxity of the joint, especially in external and internal rotation. The device for measuring rotation of a first joint of an object comprises an orthosis for immobilizing a second joint of the object, the second joint being connected to the first joint by a bone of the object; a torque sensor fixed to the orthosis for monitoring a value of torque applied to the second joint, the applied torque being transferred to the first joint via the bone; and a motion sensor for tracking a rotational displacement of the bone occurring under the applied torque.

Abstract: A finger prosthesis comprising a tip for simulating different functions of a finger and a ring for attaching the prosthesis to a stump. The finger prosthesis further includes a joint coupled between the tip and the ring, wherein the joint includes an interlocking mechanism configured to allow the joint to rotate at lockable intervals so as to lock the tip into different positions during a flexion period of the finger prosthesis.

Abstract: Devices and methods for preventing ankle sprain injuries. To protect the ankle joint from acute ankle supination or inversion sprain injuries, the device comprises a sensing part configured to sense data of an ankle motion; an analyzing part configured to analyze the data to judge whether the motion is a sprain motion; and a stimulating part configured to stimulate one or more lower limb muscles against the motion in light of a result of the analyzing. The method also involves sensing data of an ankle motion; analyzing the data to judge whether the motion is a sprain motion; and stimulating one or more lower limb muscles against the motion if the motion is a sprain motion.
