Abstract

Background and Purpose:

After stroke, many individuals lack resources to receive the intensive rehabilitation that is thought to improve upper extremity motor function. This case study describes the application of a telerehabilitation intervention using a portable robotic device combined with a home exercise program (HEP) designed to improve upper extremity function.

Case Description:

The participant was a 54-year-old man, 22 weeks following right medullary pyramidal ischemic infarct. At baseline, he exhibited residual paresis of the left upper extremity, resulting in impaired motor control consistent with a flexion synergistic pattern, scoring 22 of 66 on the Fugl-Meyer Assessment.

Intervention:

The participant completed 85 total hours of training (38 hours of robotic device and 47 hours of HEP) over the 8-week intervention period.

Outcomes:

The participant demonstrated an improvement of 26 points on the Action Research Arm Test, 5 points on the Functional Ability Scale portion of the Wolf Motor Function Test, and 20 points on the Fugl-Meyer Assessment, all of which surpassed the minimal clinically important difference. Of the 17 tasks of the Wolf Motor Function Test, he demonstrated improvement on 11 of the 15 time-based tasks and both strength measures. The participant reported an overall improvement in his recovery from stroke on the Stroke Impact Scale quality-of-life questionnaire from 40 of 100 to 65 of 100. His score on the Center for Epidemiologic Studies Depression Scale improved by 19 points.

Discussion:

This case demonstrates that robotic-assisted therapy paired with an HEP can be successfully delivered within a home environment to a person with stroke. Robotic-assisted therapy may be a feasible and efficacious adjunct to an HEP program to elicit substantial improvements in upper extremity motor function, especially in those persons with stroke who lack access to stroke rehabilitation centers.
