The femoral Slump test in patients with anterior knee pain
Anterior knee pain (AKP) is a very common musculoskeletal condition, yet the evidence regarding its etiology remains rather inconclusive. Amongst several predisposing factors, a minor damage in the femoral nerve has been recently proposed to contribute to AKP. Thus, the aim of this study was to evaluate and compare the responses to the neurodynamic femoral slump test between individuals with or without AKP.
Thirty subjects with AKP and thirty matched without AKP underwent a femoral slump test. The results of the study indicate the existence of a subgroup amongst those with AKP that present with a positive femoral slump test and increased mechanosensitivity of the femoral nerve.
These findings might be suggestive of the contribution of a neural component to the occurrence of clinical symptoms in AKP. Although this study provides important clinical implications, more research is necessary to establish a cause effect relationship between increased femoral nerve mechanosensitivity and AKP, and the role of it in the management of AKP.
