Technical evaluation of and clinical experiences with the SCRIPT passive wrist and hand orthosis

Rehabilitation robots are useful tools to objectively quantify and treat post-stroke impairments. The SCRIPT Passive Orthosis (SPO) is an passively actuated hand orthosis that can be used for interactive therapy at home. In the last year the SPO was used independently by 24 patients in three EU countries. In this paper we report on the technical challenges this has presented and the feedback we were given by therapists and patients. This includes the range-of-motion of the device, the assistive characteristics, the potential for grasp detection, and the user acceptance.
