Clinical Trial Summary

This project aims to test a new technology that may improve hand function impaired from a stroke, thereby improving independence and quality of life.


Clinical Trial Description

Post-stroke hand impairment is highly prevalent and severely restricts functional ability and independence. Yet, there is no assistive device to help hand function at home, every day, during activities of daily living. Existing devices such as hand-opening orthoses are expensive, uncomfortable, bulky, and meant for use during short therapy sessions as opposed to during daily living. Thus their impact is limited. Consequently, the development of efficacious and affordable assistive device is of importance. This project addresses this critical gap by providing an innovative patent-pending technology. The "TheraBracelet" is a wristband applying imperceptible vibration to skin. TheraBracelet is efficacious, as it has been shown to immediately improve chronic stroke survivors' touch sensation and hand dexterity in previous studies. TheraBracelet is affordable by using only a low-cost vibrator. TheraBracelet is also translational, because a vibrator strategically placed at the wrist does not interfere with dexterous finger motions, and it is low-risk by involving only imperceptible vibration on skin. These practicalities assure easy adoption in home environment for large impact on sensorimotor impairment. The essential next step, thus the objective of this Phase I project, is to determine the feasibility and safety of using this assistive device all day every day for a month during daily activity. This objective will be accomplished in a double-blinded, randomized, controlled, crossover design study. Feasibility (compliance of using the device everyday) and safety will be assessed for the real vibration condition compared to the sham vibration condition (wearing the device without vibration). The feasibility and safety level comparable to those of wearing a watch and of a comparable FDA-approved device will support viability of TheraBracelet with necessary regulatory approvals. This project is expected to lead to an assistive wristband that increases hand function during activities of daily living for a large number of stroke survivors with hand impairment. ;
