Abstract

Athletic groin pain (AGP) is a chronic, painful condition which is prevalent in players of field sports that require rapid changes of direction. Following successful rehabilitation, systematic changes have been observed in the kinetics and kinematics of pre-planned change of direction manoeuvres, providing insight into potential foci for rehabilitation monitoring and for the assessment of interventions. However, changing direction in field sports is often reactive rather than pre-planned, and it is not known whether such post-rehabilitation changes are seen in reactive manoeuvres. We analysed the stance phase kinetics and kinematics of a 90° reactive cutting manoeuvre in 35 AGP patients before and after a successful exercise intervention programme. Following the intervention, transverse plane rotation of the pelvis towards the intended direction of travel increased, and the body centre of mass was positioned more anteriorly relative to the centre of pressure. Ankle dorsiflexion also increased, and participants demonstrated greater ankle plantar flexor internal moment and power during the second half of stance. These findings provide insight into mechanical variables of potential importance in AGP, as identified during a manoeuvre based on a common sporting task.
