Effects of Robot-assisted Arm Training in Patients with Subacute Stroke

OBJECTIVE: To investigate the effects of robot-assisted arm training on motor and functional recovery of upper limb in patients with subacute stroke. METHOD: Thirty one subacute stroke patients were randomly divided into 2 groups. Robot-assisted arm training group received robot-assisted therapy using Armeo(R)Spring (Hocoma Inc., Zurich, Switzerland) for thirty minutes per day and five times every week during four weeks while control group received conventional arm training with same duration and frequency as robotic group. Outcome measures were used manual muscle test (MMT) for motor strength, Fugl-Meyer assessment (FMA), Manual function test (MFT) for arm function, Korean-modified Barthel index (K-MBI) for activities of daily living, Korean-mini mental state examination (K-MMSE) and Computerized Neuro-Cognitive Function test software-40 (CNT-40) for cognitive function. All recruited patients underwent these evaluations before and after four weeks robot-assisted arm training.
Robot-assisted training on upper limb after subacute stroke showed improvement on motor strength, arm function, and activities of daily living. But change values in terms of MMT, FMA, MFT, K-MBI exhibited a no statistically significant difference compared with conventional group (p>0.05).
In patients with upper limb deficits after subacute stroke, Robot-assisted arm training was considered to facilitate motor and functional recovery of upper limb. But robot-assisted arm training did not significantly improve motor and arm function at 4 weeks compared with conventional arm training group. Further research is required about the comparison of conventional rehabilitation therapy group and the questions about the duration, severity of stroke.
