Clinical Trial Summary

This project consists of two parts: Robotic Rehabilitation Trials, and Study of Outcome Predictors and Clinimetric Attributes. In the first part of study, the investigators aim to (1) investigate the treatment effects of robot-assisted therapy (RAT) in patients with stroke on various outcomes, (2) test the dose-response relations by using two different intensities (higher versus lower intensity RAT), and (3) investigate the effects of the training intensity on a biomarker of oxidative stress. Treatment outcomes will encompass the spectrum of functioning including motor ability, motor control strategies, basic/extended daily functions, mobility, community reintegration, quality of life, and biomarker (8-OHdG). In the second part of study, the purposes are to define the appropriate populations for RAT and to examine the clinimetric properties of clinical measures relevant for use in robotic rehabilitation research. the investigators will identify the clinical predictors that will potentially influence the functional outcomes after interventions. Finally, the investigators will examine and compare the clinimetric properties (e.g., validity and responsiveness) of the clinical measures of rehabilitation outcome to inform selection of test instruments that may detect clinically meaningful change after rehabilitation therapy.

Intervention

Other:
Robot-assisted therapy
Patients will receive an intervention for 20 training sessions (1.5 hours/day, 5 days/week for 4 consecutive weeks). The Robot-assisted arm trainer, Bi-Manu-Track (Reha-Stim Co., Berlin, Germany), will be used in this project. The Bi-Manu-Track enables the symmetrical practice of 2 movement patterns: forearm pronation-supination and wrist flexion-extension (Hesse et al., 2003; Hesse et al., 2005). Each movement has three computer-controlled modes: (1) passive-passive, with both arms being moved by the machine with speed and range of motion individually adjustable; (2) active-passive, with the nonaffected arm driving the affected arm in a mirror-like fashion; and (3) active-active, with both arms actively moving against resistance. Mode 3 is an active mode as in 2, but the paretic arm had to overcome an individually set, initially isometric resistance to allow the bilateral movement. The speed of movement, the amount of resistance, and the range of movement can be adjusted individually.
