Research summary
Atraumatic shoulder instability (ASI) is an abnormal symptomatic motion of the shoulder resulting in pain, functional impairment, subluxation or dislocation of the shoulder in the absence of trauma. Conservative management is generally recommended for this patient group however there is a paucity of data available to guide rehabilitation management and appears to be based on opinion rather than high quality evidence. A greater understanding of strength and function of the shoulder joint in the ASI population, and any deficits when compared with matched controls, might provide insightful information pertinent to the development of evidence-based effective interventions. Hence, the aim of this pilot study is to profile shoulder strength, range of motion and proprioception in the ASI population and compare these with matched controls. This pilot study might assist the planning and development of larger studies on pathways for diagnosis, assessment, and interventions.
Brief methods: 12 ASI patients will be recruited from an Advanced Physiotherapy Practitioner instability clinic at York Hospital and matched with 12 controls recruited from users of York St John University campus. All testing will take place at Haxby Road Sports Park, York. After providing written consent, participants will complete a series of questionnaires to determine any contraindications for exercise, demographics to match control participants, their preferred hand, extent of their instability and shoulder discomfort. Physical tests will be performed on the participants’ symptomatic shoulder. Active and passive range of motion in three directions (flexion and extension, abduction and external rotation) will be measured in using an inclinometer. Strength will be measured in the Athletic Shoulder (ASH) Test, Isokinetic Dynamometry (internal-external rotation and scapula plane elevation) and hand grip dynamometry. Participants’ shoulder proprioception (sense of force and sense of position) in internal-external rotation will be assessed whilst seated on the Isokinetic dynamometer.REC name
