Objective: To investigate the effects of short-term robot-assisted upper limb training on hemiplegicpatients compared to conventional physical therapy.
Method: This study was a prospective, single-blinded, randomized controlled trial. Eighteen hemiplegicpatients due to brain lesions were randomly assigned to: (1) robot-assisted upper limb training andconventional upper limb physical therapy for 30 min a day, respectively (Robot group); or (2) conventionalupper limb physical therapy for 30 min twice a day (Conventional group). All interventions were providedfor 2 weeks, 5 times a week. Each patient was evaluated at pre- and post-treatment by the Fugl-Meyerassessment-upper extremity (FMA-UE), Jebsen hand function test (JHFT), grip power, modified Barthelindex-upper extremity (MBI-UE), line bisection test, and Albert test.
Results: The Robot group showed significant improvement in FMA-UE (pre: 13.22 ± 14.20, post: 21.67± 15.84; p = 0.018), MBI-UE (pre: 14.33 ± 7.42, post: 16.56 ± 6.95; p = 0.041), and line bisectiontest (pre: 25.15 ± 34.48, post: 14.93 ± 28.38; p = 0.043). The Conventional group showed significantimprovement only in MBI-UE (pre: 9.22 ± 6.06, post: 15.56 ± 6.19; p = 0.008). The improvementin MBI-UE was larger in the Conventional group than Robot group (6.33 ± 3.28 vs. 2.22 ± 2.49; p= 0.014).
Conclusion: This study suggests that short-term robot-assisted upper limb training may improve upperlimb function in hemiplegic patients. However, proper physical therapy may be needed to transferimproved upper limb function to activity of daily living. In addition, goal-directed reaching tasks usinga robot are expected to be a treatment option for hemineglect.
