【Abstract】Objective To investigate the effect of Rosenthal effect cognitive training combined with isokinetic muscle training on muscle strength, walking function and negative emotion in elderly patients with stroke after total knee arthroplasty (TKA). Methods A total of 121 elderly patients with stroke after total knee arthroplasty (TKA) in our department were enrolled and divided into 2 groups by coin tossing. 60 cases in the control group were given early full-course isokinetic training, and 61 cases in the observation group were combined on this basis Cognitive training intervention based on the Rosenthal effect, the knee muscle strength, walking function and negative emotions of the two groups were compared. Results After the intervention, the flexion and extension range of motion and step length of the hip and knee joints in the observation group were higher than those in the control group (P<0.05); the peak moments of knee flexor and extensor muscles in the observation group were significantly higher than those in the control group (P<0.05) ); The IDA scores of anxiety and depression in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Rosenthal effect cognitive training combined with isokinetic muscle strength training can effectively enhance the muscle strength of the knee flexors and extensors in elderly patients with stroke after TKA, improve the range of motion of the hip and knee joints, reduce the patients’ negative emotions, and benefit the prognosis of the patients.
