This document describes a project to design a portable thumb exoskeleton device to assist stroke patients in opening and closing their thumb. The goal is to allow patients to regain independence without needing constant physician assistance. A team will design and test prototypes, getting feedback from stroke patients. Improvements like an internal battery holder and pressure sensor will be implemented. If successful, the low-cost portable device could help patients and reduce medical costs for stroke rehabilitation.
A Project On Robotic Exoskeleton Arm (3) (2) 2.ppthuzefa ansari
Exoskeleton is an outer framework that can be worn on a biological arm. It is powered by actuators and can provide assistance or increase the strength of the biological arm, depending on the power of the actuator. Electromyography(EMG) is the suitable approach for human-machine interface with the help of exoskeleton.
When working with EMG we actually measure the motor unit action potential [MUAP] generated in the muscle fibers. This potential builds up in the muscles when it receives a signal from the brain to contract or relax.

The EXCITE Trial: Retention of Improved Upper Extremity Function Among Stroke Survivors Receiving CI Movement Therapy.(2008)
The Extremity Constraint Induced Movement Therapy Evaluation (EXCITE) demonstrated that CIMT administered 3-9 months post-stroke, resulted in statistically significant and clinically relevant improvement in upper extremity function during the first year compared to those achieved by participants undergoing usual and customary care.
This study was the first randomized clinical trial to examine retention and improvements for the 24 month period following CIMT therapy in a subacute sample.
Study design - single masked cross-over design, with participants undergoing adaptive randomization to balance ,gender, prestroke dominant side, side of stroke, and level of paretic arm function across sites.
CIMT was delivered up to 6 hours per day, 5 days per week for 2 weeks.
Subsequent evaluations were made after the two week period, and at 4, 8, and 12 months.
Because the control group was crossed over to receive CIMT after one year.
Primary outcome measures – Wolf Motor Function Test

Secondary outcome measure - Stroke Impact Scale (SIS)
were assessed at each of these time intervals, was administered only at baseline, 4, 12, 16 and 24 month evaluations.
Result :There was no observed regression from the treatment effects observed at 12 months after treatment during the next 12 months for the primary outcome measures of WMFT and MAL.
In fact, the additional changes were in the direction of increased therapeutic effect. For the strength components of the WMFT the changes were significant (P < .05) Secondary outcome variables, including the SIS, exhibited a similar pattern.

1. Thumb Exoskeleton
Robotic Rehabilitation — The independent patient.
Advisor: Professor David Reinkensmeyer, Ph. D.
Background
Stroke patients have difficulties with
their hand movement and any currently
in post-stroke rehabilitation are being
treated by physicians with machines that
assist the patient in small hand tasks.
However, these methods are costly and
do not allow for the patient to have their
own assisting device with them at all
times.
Project Goal
• Design a portable exoskeleton device
aimed at assisting a patient open and
close their thumb.
Objectives
• Have stroke patients test the
effectiveness of a prototype.
• Improve the overall design of the
project after various modifications and
tests.
Future Progress
• Design a internal battery holder for changing
battery easily
• Modify joystick to a comfortable position for
controlling
• Implement a pressure sensor to the design.
Project Significance
• 795,000 Americans each year have a stroke and
8 out of the 10 survivors will suffer from
Hemiparesis, or one-sided weakness in the body.
• Patients can become independent from a
physician with a thumb exoskeleton.
• Medical bills for these patients can also be
reduced in the process.
