Objective:To investigate the effects of internet-based cognitive-behavioral therapy(iCBT)on kinesiophobla and rehabilitation outcomes in patients undergoing total knee arthroplasty.Method:A total of 142 patients undergoing total knee arthroplasty were randomly divided into control group and experimental group.The control group received routine nursing intervention,while the experimental group received iCBT intervention in addition to routine car.General data questionnaire,Tampa Scale of Kinesiopho-bia,Self-Efficacy for Rehabilitation Outcome Scale and Hospital for Special Surgery knee score were assessed on postoperative day 2,day 14,at 1 month and 3 months.Result:Between the two groups,there were statistically significant differences in the kinesiophobia score,re-habilitation self-efficacy score and knee function score at the 3rd day,14th day,1 month and 3 months after operation in the experimental group(P＜0.05).Conclusion:iCBT intervention can alleviate the level of kinesiophobla,improve rehabilitation self-efficacy and promote the recovery of knee function in patients after total knee arthroplasty.

Objective:To assess the impact of different exercise modalities on cognitive and physical functions in elderly patients with cognitive frailty using a network meta-analysis based on frequency theory.Methods:A comprehensive computer and manual search was conducted in PubMed, Web of Science, Embase, CINAHL, Cochrane Library, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc for randomized controlled trials on the effects of exercise training on cognitive and physical functions in elderly patients with cognitive frailty. The search covered studies published until December 31, 2023. To ensure the rigor of the study, two researchers independently screened the literature, evaluated the quality using the Cochrane risk of bias tool, and extracted data. Statistical analysis was conducted using Stata 14.0 software.Results:A total of 16 studies were included, involving 10 different exercise interventions (Baduanjin, Tai Chi Chuan, Mindfulness-based Tai Chi Chuan, Otago exercise, high-intensity interval training, dual-task exercise training, multicomponent exercise, aerobic exercise, resistance exercise, and combined aerobic and resistance exercise). The network meta-analysis results showed that, compared with non-exercise control groups, Baduanjin and dual-task exercise training improved cognitive function in elderly patients with cognitive frailty ( P<0.05), with Baduanjin showing the best effect ( SUCRA=0.79). Multicomponent exercise improved frailty ( P<0.05) with the best effect ( SUCRA=1.00), it also improved grip strength ( P<0.05), with the best effect ( SUCRA=0.89). Multicomponent exercise and dual-task exercise training improved walking speed ( P<0.05), multicomponent exercise had the best effect ( SUCRA=1.00) . Conclusions:Baduanjin has an advantage in improving cognitive function in elderly patients with cognitive frailty, while multicomponent exercise is more effective in improving frailty, grip strength, and walking speed. However, the conclusions of this study need further validation.
