Background: Knee and ankle injuries have a higher incidence rate in female than \nmale athletes. Dynamic knee valgus (DKV) has been highlighted as a cause of \nnon-contact knee injuries. \nAim: The main aim of the study was to identify the relationship between hip range \nof motion (ROM) and DKV. \nRationale: Previous studies have focused on the relationship between hip \nstrength and DKV; and have identified possible relationships between lower limb \nROM and DKV. Prehabilitation programmes focusing on reducing DKV in female \nathletes may reduce injury rate. Therefore causes of DKV need to be identified. \nMethod: 15 female Participants underwent hip adduction, hip external rotation \n(ER) and dorsiflexion ROM tests. Participants were also video recorded \nperforming single and double legged squats. A 2D analysis of participant’s squats \ncalculated lower limb valgus alignment measurements. ROM and alignment \nmeasurements were then correlated. \nResults and Discussion: Non-dominant single leg measurements show fair \ncorrelation between hip ER and DKV (r=0.31), suggesting as hip ER increases so \ndoes DKV. However dominant single leg measurements (r= -0.38) and double leg \nmeasurements suggest as hip ER decreases DKV increases- supporting \nhypothesis. Non-dominant single leg measurements (r=0.33) suggest as Hip \nadduction increases so does DKV- supporting hypothesis. However non -dominant \ndouble leg measurements (r= -0.42) and all dominant leg measurements suggest \nas hip adduction increases DKV decreases. Single leg measurements (r= 0.29) \nsuggest as dorsiflexion increases so does DKV. However double leg \nmeasurements (r= -0.62) suggest as dorsiflexion decreases, DKV increases – \nsupporting hypothesis. Q angle had little correlation with DKV. \nConclusion: Hip ROM and DKV are fairly correlated; further research is required \nto create effective prehabilitation programmes focusing on hip ROM to reduce \nDKV in young active females. This study also provides a basis for future research \ninto relationships between dynamic knee valgus and standing valgus alignments, \ndominant and non- dominant limb valgus and single and double legged valgus.
