ABSTRACT
Objective To compare problem-based learning (PBL) versus lecture-based learning (LBL) in the teaching of rehabilitation medicine in China.Methods All Chinese articles on PBL and LBL in teaching of rehabilitation medicine courses indexed in CBMdisc,Wanfang database,CNKI database,and Google academic search published prior to October 2017 were included.The methodological quality of the selected studies was assessed with'Cochrane Quality Evaluation Standard'.Meta analyses were performed using RevMan 5.3.Results After exclusion of non-eligible citations,a total of 18 documents involving 1943 subjects were satisfied the criteria and were included in this review.Meta-analyses revealed that PBL had a significant improvements on theoretical knowledge examination scores (MD=9.26,95％CI=5.24 to 13.29),practical skills examination scores (MD=12.11,95％CI=5.17 to 19.06),performance excellent rate (RR=3.90,95％CI=2.10 to 7.26),and patient satisfaction rate (RR=8.98,95％CI=4.23 to 19.07) (P＜0.05) among students compared with LBL in teaching of rehabilitation.Conclusion In this meta analysis,PBL is superior to LBL and worthy popularizing in teaching of rehabilitation.
ABSTRACT
Objective To evaluate the effects of whole-body vibration (WBV) training on low extremity muscle strength and mobility in older adults by a meta-analysis. Methods Articles were searched from Cochrane Central Register of Controlled Trials, PubMed, EMbase, Elsevier, CBMdisc, Wanfang database and CNKI database, and the reference list of each eligible article were also included. Randomized controlled trials which investigated the effect of WBV on mobility and low extremity muscle strength were included in this article. The meth-odological quality of each selected article was rated by the Jadad Scale. The data on patients' characteristics, type of WBV intervention and outcomes were extracted. A meta-analysis was then performed. Results 15 randomized controlled trials involving 803 subjects were includ-ed finally. 8 were considered to have good or excellent methodological quality and the rest was rated as fair. Meta-analyses revealed that WBV had a significant treatment effect on leg extension isometric strength (MD=10.11, 95%CI 0.46-19.76), knee extension dynamic strength (MD=7.98, 95%CI 2.60-13.36), and functional measures of mobility such as performance in Timed-Up-and-Go test (MD=1.39, 95%CI 0.73-2.04), and performance in five times sit to stand test (MD=1.62, 95%CI 0.25-2.98) (P0.05), among older adults compared with the control group. Conclusion WBV may be effective on improving the low extremity muscle strength and mobility among older adults.
