The WILMER Elbow Orthosis

The WILMER elbow orthosis enables patients with a paralysed elbow to actively move their flail arm again. A purely mechanical spring mechanism compensates the gravity forces acting on the forearm of the patient. An automatic locking mechanism enables the patient to retain the flail arm in two positions: one at a nearly extended elbow position and another at a 90deg elbow angle. Due to the unilateral construction the orthosis has a low mass, is easy to don and doff, and it can be worn at the medial side of the arm underneath the clothing. The separate and body adaptive fittings provide an excellent comfort of wearing.
