Background: Mild cognitive impairment (MCI) can be a stage of pre-dementia. Although the traditional Chinese exercise (TCE) has benefits associated with cognitive functions, the effects of the TCE on cognitive functions of older patients with MCI remain controversial. This study performs a meta-analysis to quantify the efficiency of TCE for older individuals on cognitive and psychological outcomes. Methods: A comprehensive database search was conducted on PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL (EBSCO), Web of Science, and four Chinese medical databases. We included trials published up to April 22, 2018, that fulfilled our inclusion and exclusion criteria. The literature was screened, the data were extracted and the methodological quality of the included trials was assessed. Meta-analyses were performed on the included data. Results: A total of 803 patients from 5 trials were included in our meta-analysis. Overall, there were no significant differences in global cognitive functions ( P = .06), memory ( P = .11), executive function ( P = .74), Verbal fluency ( P = .45) and depression ( P = .89) between the TCE and the control groups. However, the TCE significantly improved the visuospatial function (SMD = 0.38, 95% CI = 0.22 to 0.54; P < .001) for individuals with MCI. Conclusions: The findings of this study suggested that the TCE was associated with significant improvement in visuospatial function but did not affect the global cognitive functions, depression and other specific cognitive domains. There is a lack of clear evidence for effects of TCE; further large, rigorously designed studies are needed.

Objective The objective of the study was to evaluate the effectiveness of telehealth‐based exercise intervention on pain, physical function and quality of life in patients with knee osteoarthritis. Design A systematic review and meta‐analysis of randomised controlled trials (RCTs). Methods Six databases (PubMed, Embase, Cochrane Library, CINAHL, PEDro and Web of Science Core Collection) were searched for relevant randomised controlled trials published from database inception to 3 June 2021. Reviewers independently screened the literature, extracted data and used the Cochrane Collaboration Risk of Bias Tool for quality assessment. A meta‐analysis and subgroup analyses, stratified by control condition, intervention duration and delivery type, were conducted by Revman 5.4. The study was reported in compliance with PRISMA statement. Results A total of 9 independent RCTs with 861 participants were included. The meta‐analysis showed that the telehealth‐based exercise interventions significantly reduced pain in KOA patients (SMD = −0.28, 95% CI [−0.49, −0.08], p < .01) and produced similar effects to controls in terms of physical function and quality of life. Subgroup analysis revealed that telehealth‐based exercise interventions were superior to the use of exercise booklet and usual care in terms of pain and physical function and were similar to face‐to‐face exercise treatment; a long‐term (>3 months) intervention and the use of web and smartphone APPs to deliver exercise interventions were associated with better pain relief and physical function. Conclusions Telehealth‐based exercise intervention is an effective strategy for KOA management during the COVID‐19 epidemic, and it is significantly better than usual care in reducing knee pain and improving physical function and was able to achieve the effects of traditional face‐to‐face exercise treatment. Although the duration and type of delivery associated with the effect of the intervention have been identified, patient preference and acceptability need to be considered in practice.

Background Anxiety disorder is a common non-motor symptom among individuals with Parkinson’s disease (PD). At present, there are no specific tools in China for assessing the anxiety level of patients with PD. This study aimed to test the reliability and validity of the Chinese version of the Parkinson Anxiety Scale (C-PAS) in Chinese patients with PD. Methods A total of 158 patients with PD at one hospital in Nanjing were recruited through convenience sampling. The C-PAS was translated into Chinese using a classic ‘forward-backward’ translation method. Reliability tests included internal consistency and test-reliability. And in addition to content, structure and criterion-related validity were performed for the validity tests. Criterion-related validity was evaluated with the Hospital Anxiety and Depression Scale-Anxiety Subscale (HADS-A). Results Results confirmed the three-factor structure of the original C-PAS with 12 items, including persistent anxiety (5 items), episodic anxiety (4 items) and avoidance behavior (3 items). Significant and positive correlations were obtained between C-PAS and HADS-A (r = 0.82, P<0.01). The Cronbach’s α and test-retest reliability of the total scale were 0.89 and 0.84, respectively. Conclusion The C-PAS has demonstrated good psychometric properties. Therefore, it can be employed in patients with PD to evaluate the condition of anxiety.
