Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Stroke survivors with hemiplegia will be evaluated by rehabilitation professionals and asked to perform a battery of assessments to test the viability and usability of a force-feedback robot that adapts to each individual subject's performance. Subsequently, they will be asked to complete post-assessment questionnaires that provide feedback to the researchers on their observations and thoughts about the therapy devices.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

TheraDrive is a low-cost robotic system for post-stroke upper extremity rehabilitation. The system uses off-the-shelf computer gaming wheels with force feedback to help reduce motor impairment and improve function in the arms of stroke survivors. Preliminary results from various studies have shown that the original TheraDrive system lacked a robust mechanical linkage which could withstand the forces exerted by patients, lacked a patient-specific adaptive controller to deliver personalized therapy, and was not capable of delivering effective therapy to severely low-functioning patients. A new low-cost, high-force haptic robot with a single degree of freedom has been developed to address these concerns. This study has two purposes: first, to test the viability and usability of the new robot system alongside the original TheraDrive system; and second, to test if low-functioning patients benefit, and if so how much, from using force-feedback therapy as opposed to devices with zero impedance. This will be done by recruiting approximately 36 human subjects. Exercises will be performed by study subjects and an adaptive controller will monitor patient performance to ensure that exercises are difficult but doable, which is important for maintaining patient motivation. It is hypothesized that not only will the new system be viable, but that it will provide better robot-assisted therapy to a large variety of patients, especially low-functioning stroke survivors with hemiplegia.

Stroke survivors with low and moderate motor deficits

Subjects with low and moderate motor deficits will 1) complete exercises with 2 commercial (joystick and wheel) and the Theradrive haptic robot after pre assessment 2) then experience 12 therapy sessions on the Theradrive haptic robot with Adaptive Feedback. 3) Assessments pre and post therapy.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Stroke survivors at least 18 years of age with hemiplegia.
* The subject's stroke must have occurred at least 3 months prior to enrollment in the study.
* Low and Moderate functioning stroke survivors as measured by Fugl- Meyer
* Not depressed
* No more than Mild Cognitive Deficit
* Participants must be able to sit upright for 4 hours at a time in Part A of the study; and 2 hours at a time, 3 days a week, for Part B of the study.
* The subject's stroke must have occurred at least 3 months prior to enrollment in the study.

Exclusion Criteria

* Greater than mild cognitive deficits
* Greater than mild depression. A member of the research team will administer Beck's Depression Inventory (BDI) to each study participant over the phone. If the participant is found to have greater than mild depression, as measured by the BDI, they will not qualify for the study.
* Receiving rehabilitation on the upper limb.
* Received Botox injections within the past 3 months.
* Suffering from contractures (chronic loss of joint motion) or debilitating spasticity in the upper extremity.
* Experiencing greater than mild pain, and/or the PI determines that the participant should no longer continue working with the novel therapy devices, the study will be stopped.
