Abstract: A device and a method for measuring wrist motion is provided. The device allows for direct determination of wrist position in the radial/ulnar and flexion/extension planes, without needing calibration or determination of the center of rotation of the wrist. The goniometer forearm component is adapted to be releasably affixed to a forearm of a user. A hand component is also provided adapted to be releasably affixed to a hand of the user. The displacement measuring devices include cables adapted to be connected to the hand component. The displacement measuring devices are configured to ultimately measure angular displacement of the hand component relative to the forearm component.

Abstract: A device and a method for measuring wrist motion is provided. The device allows for direct determination of wrist position in the radial/ulnar and flexion/extension planes, without needing calibration or determination of the center of rotation of the wrist. The goniometer comprises a forearm component locating at least three displacement measuring devices. The forearm component is adapted to be releasably affixed to a forearm of a user. A hand component is also provided adapted to be releasably affixed to a hand of the user. The displacement measuring devices include cables adapted to be connected to the hand component. The displacement measuring devices are configured to measure angular displacement of the hand component relative to the forearm component. Two of the cables may be provided adjacent and substantially parallel to each other at substantially the same height above the base of the forearm component.
