Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Target follow-up type
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.

Outcomes
Primary outcome [1] 320760 0
Sum score of visual analogue scale ratings of physical and psychological stress
Timepoint [1] 320760 0
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.
Secondary outcome [1] 372754 0
Playing load - session rating of perceived exertion (sRPE)
Timepoint [1] 372754 0
Assessed daily or, at a minimum, bi-weekly post-enrollment throughout 6-month sampling period
Secondary outcome [2] 372755 0
Musical performance - self-rated visual analogue scale
Timepoint [2] 372755 0
Assessed daily or, at a minimum, bi-weekly post-enrollment throughout 6-month sampling period
Secondary outcome [3] 372756 0
Psychomotor performance - recognition reaction time test assessed via study-specific online platform
Timepoint [3] 372756 0
Assessed daily or, at a minimum, bi-weekly throughout 6-month post-enrollment sampling period
Secondary outcome [4] 372757 0
Physical performance - grip strength test assessed using hand dynamometer
Timepoint [4] 372757 0
Assessed weekly post-enrollment throughout 6-month sampling period
Secondary outcome [5] 372758 0
Playing-related musculoskeletal disorder incidence - modified Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians

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.
