Title: Device for acute rehabilitation of the paretic hand after stroke Team: Sasha Cai Lesher-Pérez (Leader) Carly Brown (Communicator) Lee Linstroth (BSAC) Nathan Kleinhans (BWIG) Date: September 14 – September 20 2007 Project Design Statement: Design a portable automated device that will facilitate hand rehabilitation in the acute phase (first three months) after stroke within a clinical setting; focus of rehabilitation will be supination/pronation movements of the wrist and gross flexion/extension of the fingers. Both active and passive movements will be focused on for rehabilitation, and the device should be able to simultaneously or independently assist rehabilitation of the two degrees of motion. Restatement of Team Goals: • Compile full list of hand flex/extension materials needed for bladder option (Lee) • Continue work on IRB (Carly, Nathan) • Continue learning C++ programming software (Sasha Cai) • Think of design options for simultaneous movement (flex/ext and sup/pro) (Nathan, Lee, Sasha Cai) • Put planks in place to wrist rotator design for wrist constriction (Nathan) • Contact client, meet with client Individual Goals: • Carly: Work on IRB protocol, receive citi human training, communicate what needs to be worked on for completion of IRB • Lee: Research aluminum rods for Hand flex/extension device, locate where sold, receive citi human training, run current tests on motor, create modeling designs of Hand flexion/extension device • athan: Research linear actuators, find ones for budgeted amount, receive citi human training, run current tests on motor, create modeling designs of hand flexion extension device • Sasha Cai: Work on C++ programming, attempt interface between h-bridge, microprocessor and motor, create technical drawings of circuits and wrist rotator. Summary of Accomplishments: 1) Met With Client 2) Met with Advisor 3) Finalized a design option for Hand flexion/extension device 4) Began Writing IRB 5) Got first round review of IRB from Client6) Ordered Microprocessor and H-Bridge 7) Began preparing software template for Microprocessor 8) Secured planks for wrist security in wrist rotator Difficulties: None Activities: Team Meeting: 09/17/07 1 hour Advisor Meeting: 09/18/07 .5 hour Client Meeting: 09/19/07 1.5
