Abstract

This paper presents a passive hand orthosis, called EXTEND, that can be used during activities of daily living. In the design a negative stiffness spring mechanism is incorporated to overcome the high finger joint stiffness of stroke patients with hypertonia. The passive mechanism can be easily tuned by the user to compensate a linear joint stiffness of 0.15 to 0.33 Nm/rad for each finger independently. A prototype was tested with four patients showing an increased functional ability of the hand during several tasks. With the orthosis, patients were better able to pick up mid-sized objects (5-7.5cm diameter) of different shapes.
