Summary

The aim of this study is to build on previous published work, which has indicated lumbar mobilisations have the ability to increase hamstring extensibility and decrease muscle activity. The primary aim of this project is investigate if lumbar mobilisations have an affect on the Nordic Hamstring exercise.

Aim: To investigate the short-term effects L4 and L5 Unilateral Posterior Anterior (UPA) Mobilisations on the lumbar spine on the Nordic Hamstring Exercise. Measures will include hamstring peak torque, sEMG activity and knee angle at first rapid change in angular acceleration.

Conditions

  • Hamstring Injury

Interventions

OTHER

Lumbar Mobilisations

The intervention will consist of unilateral lumbar mobilisations at the L4 and L5 level in a Posterior Anterior direction. The side of the mobilisation will be determined by dominant leg - considered the kicking foot. The mobilisations will be administered by a physiotherapist with at least 10 years clinical experience. Teksan grip sensors will be worn by the physiotherapist to calculate the force applied to the participant. Grade three mobilisations will be applied for a one minute period three times at both L4 and L5 level. Each level will be determined by a passive physiological intervertebral movement. Participants will receive the mobilisations at L5 first for one minute followed by L4. This is an appropriate dose for mobilisation application (Maitland, 2013). This process will be carried out three times.
