Rehabilitation of stage-one scapholunate instability (ReSOS): An online survey of UK practice.

Introduction: Scapholunate instability is one of the most frequent types of wrist instability, but optimal management is not established. This research aims to identify current conservative management strategies for stage-one scapholunate instability and how these interventions are evaluated in the UK.

Methods: A cross-sectional online survey of UK physiotherapists and occupational therapists with self-reported experience in the rehabilitation of stage-one scapholunate instability (ReSOS), was developed using the CROSS guideline and a clinical vignette. The frequency of treatment strategies was collated via a five-point Likert-type scale and evaluation strategies via fixed-response answers at three-to-six, seven-to-eleven and after 12 weeks post-injury. Data were analysed descriptively.

Results: Forty-three electronic surveys were completed and analysed. Thirty physiotherapists and 13 occupational therapists responded, with 90% working in the NHS. Activity advice and education was the most frequently used treatment at all time-points (100%, 98%, 98%). Quick-DASH was most frequently used region-specific patient reported outcome measure at all time-points (72%, 60%, 67%).

Discussion: Despite some identified themes, including neuromuscular rehabilitation strategies, the supporting evidence is limited in the ReSOS. It is unclear what rehabilitation and evaluation strategies are optimal and the development of a consensus on best practice is recommended.
