Description of intervention(s) / exposure
A 12 week exercise program will be delivered by a registered physiotherapist who has completed training in prescribing exercise for rotator cuff tendinopathy. Participants will attend 7 sessions with their physiotherapist, a minimum of 3 sessions will be face to face. Participants have the option to complete the remaining 4 sessions as face to face appointments or via telehealth if they prefer. Participants will be randomised into two different exercise programs.
Both groups will complete the same 3 shoulder exercises (shoulder press, lateral shoulder raise, bent over row). One group will complete high load-volume exercise and the other group will complete low load-volume exercise (see next section). Based on evidence from previous trials, including 2 large randomised trials published in 2021 (GRASP and SEXSI trials), it is unclear if one exercise program is superior to the other.

Arm 1 - High load-volume: This group will complete three shoulder strengthening exercises (1. Shoulder press, 2. Lateral shoulder raise, 3. Bent over row) with progression over time, three times per week over 12 weeks. In total participants will complete 36 sessions with 7 of these sessions being supervised by their treating physiotherapist as above. The rest of the sessions will be completed by the patient independently at home. Exercise sessions are expected to take approximately 20-30 minutes at most. The intensity (load) will be progressed over time in order to target the desired level of work based on an auto-regulatory approach (repetitions in reserve). The target repetitions in reserve starts at 3-5 and progresses to 1-2 by the final weeks. Participants will use dumbbell weights as resistance in order to meet the intended intensity, reps in reserve target. The number of sets and repetitions begins at 3 sets of 8 and progresses to 5 sets of 4 by week 12. The total volume (sets x reps) is 858 over the 12 weeks. Participants will be advised to take 2-3 minutes rest between sets. The treating physiotherapist will progress and regress the exercises in accordance with the patients level of pain, discomfort and level of fatigue. Participants and when supervised the treating physiotherapist will progress or regress the intensity (load) in order to achieve the target repetition in reserve for that session.


Information relevant to both the intervention and control groups
Education
Participants in both groups will receive education material based upon current evidence and guidelines in order to help them understand their shoulder pain and how to best manage it. This education material has been developed for this trial and has been updated from education materials previously used by our research group. The material will be available electronically and if preferred a printed version will be supplied.
Education material will be delivered via their treating physiotherapist and outlines the shoulder joint anatomy, the usual presenting symptoms of rotator cuff tendinopathy, the causes and contributing factors, how rotator cuff tendinopathy is diagnosed, whether a scan is necessary, the recommended guideline based treatments, the potential benefits and harms for treatments including surgery and exercise, guidelines for pain and exercise and how long it usually takes for rotator cuff tendinopathy to improve.

Intervention fidelity will be checked for each treating practitioner (minimum of one session) via audio or video recording.
Participants progress will be monitored via fortnightly pain questionnaire throughout the duration of the 12 week program and using functional questionnaires at 6, 12 and 26 weeks from the commencement of the intervention. Participants will also complete measurements for strength at baseline pre intervention commencement and again at 6, 12 and 26 weeks post intervention commencement.

Exercise adherence: Participants will record their completed exercise via an online form / exercise diary. Participants will be asked to wear an IMU activity tracking sensor on the wrist of their affected shoulder for as much of the 12 week intervention program as able. Data collected from this sensor will be analysed to determine velocity of movement, number of sets and repetitions for each exercise and general physical activity / sleep.

Details of the exercise program for both groups:
1. Administered by a registered physiotherapist who has completed training in exercise for rotator cuff tendinopathy
2. Exercise will be delivered via face to face sessions, with the option of several telehealth sessions if preferred (total 7 sessions with a minimum of 3 face to face). Education material will be provided in written format (paper or electronic) and will be reviewed by the treating physiotherapist during the treatment sessions.
3. Participants will attend 7 supervised physiotherapy sessions over 12 weeks. They will complete the remaining sessions at home independently.
4. Both groups will be advised to continue with their exercise program throughout the 12 week intervention if they have pain which they consider acceptable, manageable or bearable. They will be advised that some pain post exercise is considered normal, provided that it has returned to their normal baseline level within 24 hours. If participants experience progressing or worsening pain that become unbearable (>5/10) during their exercises they will be advised to reduce the range of movement, reduce the load or intensity if applicable or to modify the exercises.

All materials will be provided to the participants via electronic written form unless they prefer a paper / print version which will be made available if required. Participants will record the number of completed sets and repetitions in an online exercise diary web form, which will also be made available in a paper version if a participant prefers.

Physiotherapists delivering the treatment will not deliver the exercise program to both groups. They will be restricted in delivering the exercise program to either the intervention group or the control group but not both.

Comparator / control treatment
Arm 2 - Low load-volume: This group will complete the same 3 shoulder exercises (1. Shoulder press, 2. Lateral shoulder raise, 3. Bent over row). These exercises will be prescribed without any added resistance or weights (load). Participants will work against gravity only. Over the course of the 12 week program the volume (sets x reps) will be equivalent between the high load-volume group and the low load-volume group. Participants will start with 2 sets of 5 and progress to 3 sets of 20 by the 12th week. Total volume for the low load-volume group is 862 repetitions (within 4 repetitions of the high load-volume group, 858).

Participants in the low load-volume group will complete 4 sessions per week over the first 4 weeks, 3 sessions per week over the second 4 weeks and 2 sessions per week for the final 4 weeks of the 12 week intervention. In total the low load-volume group will complete 36 exercise sessions (the same as the high load-volume group). Of these 36 sessions, 7 sessions will be supervised during their scheduled physiotherapy appointments, the remaining sessions will be completed independently at home. This is the same number of supervised sessions as the intervention group.

Exercise sessions are expected to take approximately 20 minutes to complete. It is anticipated that the low load-volume group may complete their exercise sessions slightly faster than the high load-volume group as they are not likely to require as long a rest period between each exercise.

The primary difference between the high load-volume group and the low load-volume group will be the load intensity.

Both groups will receive the same educational material as described above.

3. Adverse events
Adverse events will be defined by any unfavourable or unintended sign, symptom or diagnosis associated with the study which may or may not be related to the intervention (e.g. fall, injury or change in medical status). Adverse events will be recorded and categorised according to the following criteria:
• Rotator cuff tendinopathy adverse event: It is anticipated that participants experience a level of discomfort or soreness as part of the routine healing process in response to exercise. Participants will be provided advice regarding an acceptable level of symptoms. An adverse event will only be recorded if it results in seeking additional care (i.e. a consultation, or taking more medication than usual).
• A serious adverse event is defined as an event related or not to the intervention that results in death, life threatening complication, hospitalisation, surgery, permanent or temporary physical disability, congenital abnormalities, or any findings the CI and/or research team feel can lead to significant health hazards. Examples of serious events include but are not limited to surgery for tendon rupture or heart attack requiring hospitalisation.
Adverse events will be recorded by a yes / no response followed by an open-response questionnaire.
Timepoint [3] 329514 0
Adverse events will be recorded via patient questionnaire emailed to participants fortnightly from the time of intervention commencement to 2 weeks post completion of the intervention (i.e. adverse event questionnaire emailed at 2 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks, 12 weeks and 14 weeks post intervention commencement).
Adverse events will be categorised as mild, moderate, severe or serious in line with the Common Terminology Criteria for Adverse Events (CTCAE5.0)

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Research staff who are not involved in outcome assessment will randomise participants off-site and inform the allocated physiotherapist. Outcome assessors, trial statisticians and researchers entering data will be blind to treatment allocation. Participants will know they are receiving an exercise intervention, but we will make it clear that we do not know which will be more effective, and will not disclose details of the interventions or our hypothesis in verbal and written materials. Further, participants will not be treated concurrently and participants will be asked not to discuss their treatment group with outcome assessors.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer-generated randomisation sequence (permuted blocks of variable size, stratified by trial site) will be created and imported into the REDCap randomisation tool by an independent administrator.

Statistical methods / analysis
As this is a feasibility trial, the main analysis will focus on process outcomes. This will include the number of potentially eligible participants, recruitment and retention rates, response rates to questionnaires and exercise adherence (% of prescribed sessions completed). The following success criteria will be used to decide trial modification/whether to proceed to full trial: (i) Recruitment rates: Consent and randomisation of 20% or more of eligible patients. (ii) Intervention adherence: 80% or more of the number of sessions completed in each group; (iii) follow-up rates of internet questionnaire outcomes of 80% or more. This feasibility trial will not be powered to identify treatments effects related to pain and function, however, baseline and follow-up between group differences will be investigated to determine potential trends in the outcomes of interest and guide design of a full-scale trial.

Summary
Brief summary
This research will investigate the effects of exercise for people with rotator cuff tendinopathy. Rotator cuff tendinopathy is the most common reason for pain among people experiencing shoulder pain. It is characterised by pain at the front or side of the shoulder and may radiate into the upper arm. Pain is typically worse when lifting the arm, completing overhead activities or generally with increased shoulder activity.
Current guidelines recommend exercise, activity modification and anti-inflammatory medication as first line treatment for rotator cuff tendinopathy. However, we do not yet know which exercise is most effective. The proposed study is a two arm parallel group randomised control trial. The primary aim of this research is to compare the feasibility of two different exercise interventions for rotator cuff tendinopathy.
