Detailed Description
The overall objective of this research is to design, fabricate, integrate, and test a lightweight and portable robotic hand orthosis intended to restore hand functionality through fully controllable individual finger actuation. This objective is based on the hypothesis that use of such a robotic hand orthosis will result in significant improvement of hand ability for adults with brachial plexus injury, as evaluated through the Southampton Hand Assessment Procedure (SHAP).
To achieve this, several novel design aspects are incorporated. The use of miniature linear actuators and lightweight materials allows for the motors and sensors to all mount atop the dorsum of the hand, and eliminate the need for bulky external actuation units. In addition, the actuators have inbuilt force sensing capabilities to provide feedback on the force being applied to each individual finger, even before contact is made with a grasped object. Furthermore, wrist flexion/extension is powered, resulting in a more realistic grasping paradigm than is commonly found in robotic orthoses. Moreover, an intuitive control system will be designed in order to fully capitalize on the controllability of each finger, allowing for varied grasp geometries and motions.
A summary of the specific aims of this study are:
Design and prototype the robotic hand orthosis with the goal of creating a uniquely dexterous, lightweight and portable device. In addition, the control methodologies required to exploit the full capabilities of the orthosis will be designed. This will result in the development of an experimental research platform to determine the viability of the design and hypothesis.
Perform a feasibility trial of the robotic orthosis device by providing it to a small cohort of adult patients suffering from paralysis due to a brachial plexus injury. The patients will be assessed via the SHAP, and their respective scores both with and without the orthosis will be evaluated to determine their level of improvement in dexterity and function.

---|---|
Experimental: Exoskeleton Glove
Perform a feasibility trial of the robotic orthosis device by providing it to a small cohort of adult patients suffering from paralysis due to a brachial plexus injury.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
SHAP (without device)
Time Frame: First hour. The total expected time for the study is about 2 hours.
|
The Southampton Hand Assessment Procedure (SHAP) has been formed based on the analysis of grip patterns, and their frequency of use in Activities of Daily Living (ADL) tasks.
|
First hour. The total expected time for the study is about 2 hours.
|
QuickDASH (without device)
Time Frame: First hour. The total expected time for the study is about 2 hours.
|
The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is a 30- item questionnaire that looks at the ability of a patient to perform certain upper extremity activities.
This questionnaire is a self-report questionnaire that patients can rate difficulty and interference with daily life on a 5 point Likert scale.
The QuickDASH is an abbreviated version of the original DASH outcome measure in comparison to the original 30 item DASH outcome measure, the QuickDASH only contains 11 items.
It is a questionnaire that measures an individual's ability to complete tasks, absorb forces, and severity of symptoms.
