Description of intervention(s) / exposure
Professional or university instrumental musicians will enter the following data or perform the following tests daily or, at a minimum, bi-weekly (unless otherwise indicated) over an active sampling period of 6-months:
1) Session rating of perceived exertion (sRPE) - duration and intensity of the participant's day of instrumental music practice/rehearsal/performance
2) Visual analogue scales - ratings of physical and psychological stress
3) Pain or injury incidence - initially a yes / no question, with a 'yes' response prompting the participant to complete the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians
4) Self-rated musical performance quality - visual analogue scale
5) Recognition reaction time test - psychomotor performance
6) Grip strength test - physical performance (*this test to be performed weekly*)
Daily inputs into the monitoring tool have been designed to take 1-2 minutes for participants to complete, and will require participants to access an online form containing items 1-5 above. Weekly grip strength tests will be performed at the location of regular rehearsals or performances. Adherence to monitoring tool inputs and grip strength test will be monitored by online entry and grip strongly test attendance logs, respectively.
Participants will receive weekly study emails containing 1) information relevant to musicians’ health and wellbeing delivered in a standardised order; and 2) personalised encouragement based on individual participation rates and patterns.

Assessed daily or, at a minimum, bi-weekly throughout 6-month sampling period.
Primary timepoint depends on incidence of overreach during the sampling period. For participants with an incidence of overreach during the sampling period, the primary timepoint is the date of overreach onset. For participants without an incidence of overreach during the sampling period, no primary timepoint is assigned and mean values throughout the sampling period will be used for analysis.

Statistical methods / analysis
Sample Size
This study is powered to detect a significant difference in weekly change in the sum of visual analogue scale ratings of physical/psychological stress between acutely fatigued vs. overloaded participants. A prior study of a self-report fatigue monitoring tool using visual analogue scale data in cyclists reported a significant difference in weekly change in fatigue and ‘readiness to train’ (d=1.39; p=.02) in in overloaded vs. acutely fatigued cyclists. Using these data, a two-tailed a=.05, 95% power and a conservative 50% adjustment for non-compliance (anticipated reduced compliance due to online survey platform and long survey duration), 136 participants are required. Given the uncertainty regarding the incidence of overload in instrumentalists (and thus the distribution between acutely fatigued & overloaded participants), this sample size is regarded as the minimum viable sample size and as many participants as possible will be recruited over the study duration.
Analysis plan
The primary outcome will be compared between participants who did vs. did not display signs of overload during their data sampling time period using a two-sample t-test. ‘Overload’ is defined as a decrease in one or more performance outcomes (musical, psychomotor, physical) equal to or greater than the ‘Smallest Worthwhile Change’ = 0.3 * baseline coefficient of variation. The average change in composite visual analogue scale ratings will be used for participants who did not display signs of overload. For participants displaying signs of overload, the change in composite VAS indicator score will be used for the week immediately preceding the performance decrement. Secondary outcomes will be analysed using t-tests and regression models as appropriate. An a=.05 will be used for all analyses and all effects will be presented with 95% confidence intervals where possible.

Summary
Brief summary
Research is now consistently demonstrating extremely high rates of pain and injury in instrumental musicians, with over 80% of instrumentalists estimated to experience pain or an injury during their career. Studies have also demonstrated that fatigue is likely to be a foundational risk factor for a range of conditions experienced by musicians. In sport, fatigue management programs have been shown to effectively prevent injuries, with similar programs predicted to have similar benefits for musicians. However, even though sport and music performance both require highly refined, elite physical performance, key differences in physical demands, training and performance schedules, and resource availability between sport and performing arts necessitate a specialised approach to fatigue management in musicians. The aim of this research project is to trial a fatigue self-management tool to enable musicians and teachers to distinguish between normal short-term fatigue and potentially dangerous physical and/or psychological overload. This tool has been developed based on a consensus-generating process involving global experts in Musicians Medicine.
