Overhead Perturbation Training for Glenohumeral Joint Instability

Summary

The purpose of the trial is investigate the benefits of a novel, newly invented exercise technique protocol relative to physiological changes in upper limb proprioception (primary) and subjective readiness for return to sport (secondary).

The intervention (Overhead perturbation training) will be compared with a control intervention (non-perturbed stimulus) in a population of type II anterior glenohumeral joint instability patients (according to the Stanmore classification of instability). Each group will be assessed at baseline for glenohumeral joint proprioception (via lazer-pointer active relocation test), as well as perceived functional level (via Western Ontario Shoulder Instability index) and Shoulder Instability-Return to Sport after Injury (SIRSI) score. They will then undertake a 6 week exercise regime which is exactly the same- except the intervention used perturbated stimulus and the control uses non-perturbed stimulus. Outcome measures are re-assessed at the end of the intervention period. Results will be assessed statistically for statistical significance.

  • Glenohumeral Subluxation

Interventions

OTHER

Overhead perturbation training

A specifically chosen weight is attached to a 1m resistance band held above the head, hanging against gravity. The participant is encouraged to sustain a static position, where the weight and band provide variable magnitude perturbations to arm position. The body position of the participant is modified to facilitate greater and lesser perturbations. Bodily movements are prescribed to encourage joint perturbation. The participant undertakes 3 sets of 25 repetitions (60s rest) and continues with variable stimulus until fatigued.

OTHER

Non-perturbed training

A weight is grasped by the participant and elevated above head to the same position as the OPT intervention. The participant is encouraged to sustain a static position. The body position of the participant is modified to facilitate greater and lesser perturbations. Bodily movements are prescribed to encourage joint perturbation. The participant undertakes 3 sets of 25 repetitions (60s rest) and continues with variable stimulus until fatigued.
