Background Stroke affects one side of the body The main goal is to help stroke patients recover faster and better than current rehabilitation methods. Range of Motion (ROM) Strength Active therapy is used to facilitate patient induced motion of affected limbs
Design Requirements Summary PDS compiled from patient and medical professional interviews Exercise more than one joint Visually unobtrusive (to patient) Small footprint Ease of use / Intuitive interface Safety
External Search Competitor Device Myomo (mPower1000) Device proves concept Limited to one motion and one part of body Comfort issues Patent Protected!
Internal Search - Brainstorming Arm Brace Robotic Arm CNC table movement Adjustable Chair/Bed Exercise Machine Table mount, wall mount, free standing, mobile
