Abstract
Background: Excessive trunk lean, medial knee movement and ankle dorsiflexion during lunge are considered deviations from ideal technique. The aim of this paper was to determine whether hip extension strength was related to trunk, knee and ankle kinematics during the step out lunge. Methods: Thirty-three healthy volunteers (18 men) were recruited (mean age 32±9, height 1.74m±0.07, weight 75kg±15). Limb dominance was determined as the preferred leg to kick a football. Hip extension strength was measured using a handheld dynamometer. The Microsoft Kinectâ„¢ captured sagittal and frontal plane movement during the step out lunge. Linear trunk, hip and knee movements were determined from three-dimensional positional change of the lower limb and spine during the lunge. Ankle dorsiflexion was measured using onscreen goniometry. Results: Correlation analysis revealed that greater hip extension strength was moderately associated with a more upright trunk during lunge for the non-dominant leg (r = -0.539; p=0.002) but not for the dominant leg (r = -0.148; p=0.428). For frontal plane knee movement, there was a fair correlation between hip extension strength and medial deviation in the non-dominant leg (r = -0.351; p =0.049) but not in the dominant leg (r = 0.067; p =0.715). Hip extension strength was not significantly correlated to dorsiflexion range for dominant (r= -0.076, p=0.69) or non-dominant legs (r=0.051, p=0.787). Conclusion: Hip extension strength has a fair to moderate correlation with trunk lean and knee alignment during step-out lunge in healthy individuals in the non-dominant limb only. No relationship exists in the dominant limb or with dorsiflexion on either limb
