  3. Stroke affects one side of the body causing weakness or paralysis • Voltage potential is not strong enough to achieve motion

  4. Solution • 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

  5. Design Criteria • PDS compiled from patient and medical professional interviews • Effectively exercise more than one joint/patient position • Lift Heaviest Limb / Carriage / Seated and Standing Positions • No perceivable reaction delay • Robust Structure • Deflection / Cable Fatigue • Safety • ROM limits / Shock Hazard

  6. External Search • Competitor Device • Myomo (mPower1000) • Device proves concept • Limited to one motion and one part of body • Two devices to accommodate both of body • Patent Protected!

  7. Internal Search - Brainstorming • Arm Brace • Robotic Arm • CNC table movement • Adjustable Chair/Bed • Exercise Machine • Table mount, wall mount, free standing, mobile

  8. Detailed Design • Mechanical • Frame System • Motors • Locking Mechanism • Electrical • Motor Driver • Power Supply • Wireless Sensors • Software

  9. Next Steps • Consolidate Electronics Package • Calibration sequence programming • Graphic interface integration • Refine Frame / Enclosure Fabrication • Refine Patient Interface • Wireless Electronics / Attachment Point • Carriage System Redesign
