Development of a preliminary evidence-based neuromusculoskeletal exercise guideline to reduce injury risk in the lower limb

Athletic participation growth has resulted in increased exposures and neuromusculoskeletal (NMSK) non-contact injuries. Based on current evidence, the primary objective of this literature review is to create a preliminary evidence-based NMSK exercise guideline, addressing these intrinsic modifiable risk factors. Systematic searches were conducted September 2014 prior to data extraction utilizing CINAHL Plus (1995 to September 2014), MEDLINE (1995 to September 2014), and Academic Search Premier (1995 to September 2014). A priori defined inclusion criteria were applied and included the following: (i) full text, (ii) published in English, (iii) peer-reviewed articles addressing injury risk of non-contact lower extremity injury, (iv) identified specific exercises aimed at reducing injury risk of non-contact lower extremity injury, were the key data extraction points of interest. 3163 potential articles were identified from the initial search, 3120 excluded with reason based on the exclusion criteria. Exclusion criteria was applied in the form of an eight item list summarized in table 2, 43 articles remained after search criteria were applied. Novel to the current body of knowledge, this review identified nine intrinsic modifiable risk factors of the NMSK system that were used as a foundation to create the exercise guideline consisting of 30 exercise techniques.
