RESUMO
BACKGROUND: Upper limb robotic rehabilitation can be beneficial to the patients when applied appropriately. HEXO-UR30A is a novel exoskeletal type upper limb rehabilitation robot that provides continuous passive motion to the shoulder joint. OBJECTIVE: The purpose of this study is to evaluate the effectiveness of HEXO-UR30A on the patient's functional change, spasticity, and range of motion (ROM). METHODS: We included stroke patients with upper limb hemiparesis of ageâ >â 19 years with spasticity grading of modified Ashworth scaleâ <â 3 and Brunnstrom recovery stageâ ≥â 4. The efficacy of the robot was investigated based on a rehabilitation program for 3 weeks. Patient's functions were compared before vs after treatment and between the HEXO group vs control. We conducted the Fugl-Meyer Assessment of the Upper Extremity, modified Barthel index, modified Ashworth scale, ROM, and Motricity Index upper limb. Patients' satisfaction was evaluated using a questionnaire after every 10 sessions of training. RESULTS: In the HEXO group, the Fugl-Meyer assessment for shoulder improved significantly (P valueâ =â .006*) compared with the control group (P valueâ =â .075). Both groups showed significant improvement (P valueâ <â .05) in Motricity Index upper limb after treatment. There were some improvements in the passive and active ROM. Patients in the HEXO group reported high satisfaction with upper limb rehabilitation. CONCLUSION: These results show that HEXO-UR30A can improve functional ability in chronic stroke patients. Moreover, the high satisfaction in patients might promote active involvement in upper limb rehabilitation.

OBJECTIVE: To investigate the clinical feasibility of a newly developed, portable, gait assistive robot (WA-H, 'walking assist for hemiplegia') for improving the balance function of patients with stroke-induced hemiplegia. METHODS: Thirteen patients underwent 12 weeks of gait training on the treadmill while wearing WA-H for 30 minutes per day, 4 days a week. Patients' balance function was evaluated by the Berg Balance Scale (BBS), Fugl-Meyer Assessment Scale (FMAS), Timed Up and Go Test (TUGT), and Short Physical Performance Battery (SPPB) before and after 6 and 12 weeks of training. RESULTS: There were no serious complications or clinical difficulties during gait training with WA-H. In three categories of BBS, TUGT, and the balance scale of SPPB, there was a statistically significant improvement at the 6th week and 12th week of gait training with WA-H. In the subscale of balance function of FMAS, there was statistically significant improvement only at the 12th week. CONCLUSION: Gait training using WA-H demonstrated a beneficial effect on balance function in patients with hemiplegia without a safety issue.
