Description of intervention(s) / exposure
Usual care for musculoskeletal shoulder pain within an orthopaedic department in a tertiary care hospital. For example, usual treatment may include conservative (physiotherapy), injection therapy, surgery.
Outcome assessment of predictor and confounding variables will occur at baseline, and clinical outcomes assessment will occur at 6, 12, and 24 months follow up.

Treatment effect modifier: Pressure Pain Threshold (PPT). PPT will be measured at baseline using a pressure algometer (Commander Echo Algometer, JTech Medical, USA). PPT is defined as the minimal amount of pressure (kg) applied to the skin at which a participant first perceives a change in sensation from one of pressure to one of pressure with discomfort/pain.

baseline
Secondary outcome [2] 365818 0
Treatment effect modifier: Conditioned Pain Modulation (CPM). CPM will be measured using a cold water bath at 8 degrees Celsius as the conditioning stimulus, and PPT as the test stimulus. Following initial PPT measures, participants will be asked to immerse their hand up to the wrist on the unaffected side into the cold water bath for a maximum of 2 minutes. PPT (applied over the middle deltoid muscle on the affected side) will be measured at 30, 60, 90, and 120 seconds during cold water immersion, and then at 30 and 60 seconds following removal of the hand from the water. The difference in PPTs between baseline and during water immersion, and from baseline to post-water immersion, will be calculated and used in further analyses.

Secondary outcome [3] 365819 0
Treatment effect modifier: Temporal Summation (TS). A 256mN weighted Pinprick Stimulator (MRC, Germany) will be used to measure mechanical TS. The weighted pinprick will be applied as a single stimulus to the middle deltoid muscle, upper trapezius muscle and between the 1st and 2nd metacarpals on the dorsum of the hand bilaterally, and an initial measure of pain severity will be recorded using a 0-10 numerical rating scale. Following this, 10 stimuli will be applied within 1cm2 of the same area with a 1-second interval between each stimulus. Participants will be asked to rate the level of pinprick pain intensity immediately following the last of the 10-stimuli train, and the difference between the last and first pain scores will be calculated as the TS score.

Statistical methods / analysis
Predictor (CPM, TS, PPT) and confounding variables (PCS, DASS-21, EQ-5D) and treatment (conservative, injections, surgery) will be assessed through their inclusion individually in the regression model, and will remain if they significantly influence the outcomes (p<0.1).
The association between the baseline predictor variables and the clinical outcomes will be evaluated using multivariable logistic regression analyses with Backward Wald selection.
