Abstract

 background  : The aim of this systematic review and meta-analysis study is to investigate the effect of warming up on knee position sense.
Method: The keywords of this review study were searched on December 1 by two authors in the following electronic databases: PubMed, web of science, Scopus, and Google Scholar. The quality of articles was checked by the Downs and Black checklist. Statistical analysis was performed using CMA software, and I-square was used for examining the heterogeneity of data and I2 was utilized for estimating the percentage of heterogeneity. Besides, Funnel Plot method was used for assessing the risk of bias of articles and trim-and-fill method was used in case of observation of possible bias.
Results: Out of 5,133 studies found in selected databases, 31 ones were selected after reviewing the title and abstract, and 7 articles were included in the study after reviewing the full text. The results indicated that warming up has a significant effect on reducing the active absolute angular error (P<0.05) and the active relative angular error (P<0.05) but has no significant effect on the passive absolute angular error (P>0.05).
Conclusion: Warming can reduce absolute and relative angular error. Therefore, it has a significant effect on improve proprioception.
