Data collection will take place prior to random allocation, half way through the intervention (6-8 weeks) and at the end of the intervention (13-15 weeks). At 26 and 52 weeks a telephone follow-up interview will repeat collection of Shoulder pain and Disability Index (SPADI) and the EuroQol questionnaire (EQ-5D-5L) and evaluate the surgical outcome. The chief investigator will perform data collection, an assistant will accompany to assist with measurement of posterior shoulder tightness. The assessor will be blind to the group allocation of participants. Where possible the participants will complete questionnaires unassisted, where assistance is required additional explanation will be provided by the research assistant. Physical data will be collected in the form of a clinical examination at baseline, 6-8 weeks and at 13-15 weeks. The examination will involve measurement of posterior shoulder tightness through the use of three clinical tests. These tests will be performed with measurement brace and digital inclinometer. A reliability study of these three clinical tests has been performed by the chief investigator at the University of Brighton following approval by the Faculty of Health Sciences Research Ethics and Governance Committee. The three clinical tests to identify patients with posterior shoulder tightness are; horizontal adduction, internal rotation in 90 degrees abduction and low flexion.
