Hip ROM and groin pain in athletes
A systematic review was conducted to determine hip ROM and its relationship with the occurrence of groin related injuries. The study concluded that the strong heterogeneity among studies makes extrapolation challenging and that caution should be taken when drawing conclusions. Despite this, the authors discourage the use of ROM as a variable in pre-screening for predicting risk of groin injury.
As it stands, consensus has acknowledged the relationship between the hip joint and groin pathology. However, for hip ROM and its role in groin related injuries, causation has yet to be determined. Previous research has alluded to the use of ROM as a risk factor for developing groin related pain, although agreement has not been reached as to how this information can be applied at a clinical level.
Concerns over dissimilarities in terminology and flaws in methodology among the analyzed studies - especially concerning inclusion/ exclusion criteria and ROM measures - reduced the ability of pooling for adequate comparison. In an attempt to draw clinical relevance, the authors make recommendations regarding clinical assessment as well as guidelines in application of outcome measurement. It is acknowledged that strong evidence exists, which links lower total ROM of both hips to groin pain. However, general ROM acts as a poor determinant in identifying athletes at risk.
