BACKGROUND & OBJECTIVE
There are several established risk factors for groin pain such as age, previous history of groin injury, reduced strength on adductor squeeze test etc. Hip related-pathology and hip range of motion (ROM) have been associated with groin pain. However, there is not enough data establishing a clear relationship between reduced hip ROM and groin pain. This systematic review primarily aimed to evaluate the presence of a relationship between hip ROM and groin pain in athletes.
Studies to be included for this review were collected through database search (Pubmed, Embase, CINAHL and SPORTDiscus), cross-references from other reviews and references from experts. Eligibility criteria for the studies to be included were prospective longitudinal and cross-sectional/case series studies assessing groin pain and hip ROM as variables in an athletic population only; and clear reporting of the relationship between groin pain and hip ROM using statistical analysis. Studies based on intervention, on hip/groin pain from an established hip-related pathology, and studies lacking ROM data were excluded. Risk of bias assessment and item assessment were done according to the Critical Appraisal Skills Programme (CASP) checklist. Strength of evidence was established by defining the levels of evidence as being strong, moderate, some or inconclusive for the included studies depending on the consistency of results.
11 studies were included in this systematic review (7 prospective cohort studies and 4 case control studies). Heterogeneity was found in the definitions of groin pain and hip ROM measurement techniques across the studies. Prospective cohort studies lasted for one
