Objective: People with hip-related pain (HRP) walk with different biomechanics compared with people without HRP. However, study conclusions are often drawn from mixed cohorts, ignoring the potential for the effect of pain on biomechanics to be sex dependent. Therefore, we aimed to investigate the differences between men and women with HRP in lower limb biomechanics during walking and the single leg drop jump (SLDJ). Methods: Football players aged 18-50 years with HRP were eligible to participate. Symptoms were quantified using the Copenhagen Hip and Groin Outcome Score (HAGOS). Biomechanical data were collected via a three-dimensional motion capture system during walking and SLDJ. Lower limb kinematics and kinetics were calculated at the hip, knee and ankle. Differences between men and women were analysed using statistical parametric mapping and t-tests. Results: Sixty-five men and 23 women participated with no difference between groups for HAGOS scores (P>0.07). Walking: During stance, men with HRP walked with less hip flexion (P<0.01) and internal rotation (P<0.01), as well as a greater ankle dorsiflexion moment (P<0.01) and impulse (P<0.01) compared with women. SLDJ: During early stance, men with HRP completed the SLDJ with less hip flexion (P=0.03) and a greater external knee flexion moment (P<0.01). In addition, men produced a greater ankle dorsiflexion moment (P<0.01) and impulse (P=0.01) compared with women. Conclusion: Differences observed were task specific at the hip and knee and joint specific at the ankle. These results demonstrate that sex may be an effect modifier in people with HRP. The use of mixed cohorts without appropriate between sex considerations should be strongly discouraged in biomechanical evaluations of HRP. Clinical implication: Evaluations and knowledge into the potential modifiable risk factors of HRP are in its infancy, however this research demonstrates that sex dependent prevention and intervention strategies may be required.
