Objective: To explore the rehabilitation effect of upper limb rehabilitation robots combined with isokinetic muscle strength training on hemiplegic patients in the recovery phase of stroke, and to provide a more effective intervention plan for clinical rehabilitation treatment. Methods: One hundred and sixty type 2 stroke patients with hemiplegia in recovery phase treated at Jintan First People’s Hospital from May 2024 to May 2025 were selected as the research subjects. They were divided into a control group (n=80) and an observation group (n=80) using a random number table method. The control group received isokinetic muscle strength training, while the observation group received additional upper limb rehabilitation robot-assisted intervention based on the control group’s treatment. The general information (age, gender, course of disease), Brunnstrum staging, Barthel index, FMA score, and facial expression pain score were compared between the two groups. Results: After treatment, the indicators of both groups improved compared to before treatment. The observation group showed significant advantages in improving various indicators. In terms of Brunnstrum staging, the number of patients in stage IV and above was significantly higher than that in the control group; in terms of the Barthel index, the increase was more significant than that of the control group (P = 0.000 < 0.001). In terms of the FMA score, the increase was more pronounced (P = 0.000 < 0.001); and in terms of facial expression pain assessment, the decrease was more evident (P = 0.000 < 0.01). Conclusion: The combination of upper limb rehabilitation robots and isokinetic muscle strength training can significantly improve the recovery of limb function and activities of daily living in hemiplegic patients during the recovery phase of stroke, and reduce pain. Compared with simple isokinetic muscle strength training, the rehabilitation effect is better, and it is worthy of clinical application.
