Abstract：Objective To evaluate the clinical efficacy of upper limb robot-assisted rehabilitation in patients af-ter rotator cuff injury surgery.Methods A total of 60 patients who underwent arthroscopic rotator cuff repair between Ju-ly 2023 and July 2024 were randomly assigned into three groups(n=20 each):conventional rehabilitation group,stand-ard robot group,and individualized robot group.All patients received physiotherapy.The conventional group received 50 minutes of conventional exercise therapy.The standard robot group received 30 minutes of conventional exercise plus 20 minutes of fixed-mode robot training.The individualized robot group received 30 minutes of conventional exercise plus 20 minutes of individualized robot training.Outcomes were evaluated using the Constant-Murley Scale(CMS),Visual Ana-logue Scale(VAS),isokinetic muscle strength testing,and range of motion(ROM).Results After 6 weeks of treat-ment,VAS scores significantly decreased in all groups compared with baseline(P＜0.05),while CMS,ROM,and isoki-netic muscle strength improved significantly(P＜0.05).There was no significant difference in VAS scores among the three groups(P＞0.05).CMS,ROM,and muscle strength values in both robot-assisted groups were significantly high-er than those in the conventional group(P＜0.05),but no significant differences were found between the standard and in-dividualized robot groups(P＞0.05).Conclusion Upper limb robot-assisted rehabilitation combined with conventional therapy can effectively improve daily function,muscle strength,and joint mobility in postoperative rotator cuff injury pa-tients.The additional benefit of individualized robot-assisted programs requires further investigation.
