Importance: Increasing evidence supports the ability of music to broadly promote well-being and health-related quality of life (HRQOL). However, the magnitude of music's positive association with HRQOL is still unclear, particularly relative to established interventions, limiting inclusion of music interventions in health policy and care., Objective: To synthesize results of studies investigating outcomes of music interventions in terms of HRQOL, as assessed by the 36- and 12-Item Health Survey Short Forms (SF-36 and SF-12)., Data Sources: MEDLINE, Embase, Web of Science, PsycINFO, ClinicalTrials.gov, and International Clinical Trials Registry Platform (searched July 30, 2021, with no restrictions)., Study Selection: Inclusion criteria were randomized and single-group studies of music interventions reporting SF-36 data at time points before and after the intervention. Observational studies were excluded. Studies were reviewed independently by 2 authors., Data Extraction and Synthesis: Data were independently extracted and appraised using GRADE criteria (Grading of Recommendations, Assessment, Development, and Evaluations) by multiple authors. Inverse-variance random-effects meta-analyses quantified changes in SF-36 mental and physical component summary (respectively, MCS and PCS) scores from preintervention to postintervention and vs common control groups., Main Outcomes and Measures: SF-36 or SF-12 MCS and PCS scores, defined a priori., Results: Analyses included 779 participants from 26 studies (mean [SD] age, 60 [11] years). Music interventions (music listening, 10 studies; music therapy, 7 studies; singing, 8 studies; gospel music, 1 study) were associated with significant improvements in MCS scores (total mean difference, 2.95 points; 95% CI, 1.39-4.51 points; P < .001) and PCS scores (total mean difference, 1.09 points; 95% CI, 0.15-2.03 points; P = .02). In subgroup analysis (8 studies), the addition of music to standard treatment for a range of conditions was associated with significant improvements in MCS scores vs standard treatment alone (mean difference, 3.72 points; 95% CI, 0.40-7.05 points; P = .03). Effect sizes did not vary between music intervention types or doses; no evidence of small study or publication biases was present in any analysis. Mean difference in MCS scores met SF-36 minimum important difference thresholds (mean difference 3 or greater)., Conclusions and Relevance: In this systematic review and meta-analysis, music interventions were associated with clinically meaningful improvements in HRQOL; however, substantial individual variation in intervention outcomes precluded conclusions regarding optimal music interventions and doses for distinct clinical and public health scenarios.

Background: Mismanagement of fatigue and playing load have been consistently identified as risk factors for playing-related pain and injuries. Studies in sport demonstrate that fatigue management strategies can predict and prevent overuse syndromes and related injuries through consistent assessment of playing load and physical/psychological stress. Self-report strategies show particular responsiveness to both the short and long-term impacts of training. No equivalent fatigue management strategies exist for musicians. Establish key items and feasibility parameters to inform the development of a self-report fatigue management tool for musicians., Methods: A working party of international experts in musicians' medicine was invited to complete a two-phase Delphi survey. In Phase I, working party members rated established items from sport (REST-Q subscales with demonstrated responsiveness to both acute and chronic training stresses) with respect to relevance and prospective utility for musicians. Members could also propose additional items and were asked to indicate a maximum feasible questionnaire length. In Phase II, working party members ranked top performing items from Phase I. Consensus best items were determined based on Phase II rankings., Results: A 28-member working party was assembled (15 clinicians, 13 researchers). Of 20 researcher proposed items and 58 working party proposed items, 5 items met consensus criteria: I had pain; I had to play too much; I felt physically fit; I did not get enough sleep; I recovered well physically. A strong majority (89%) of working party members indicated that regular use of a fatigue questionnaire with up to 10 items is feasible., Conclusions: Key questionnaire items and feasibility parameters for a novel fatigue management tool for musicians are established. Future research in musicians is needed to validate study results and this novel fatigue management tool.

Background: Warm-up is commonly recommended for injury prevention and performance enhancement across all activities, yet this recommendation is not supported by evidence for repetitive submaximal activities such as instrumental music performance., Purpose: The objective of this study is to quantify the effects of cardiovascular, core muscle, and musical warm-ups on muscle activity levels, musical performance, and subjective experience in skilled violinists., Methods: Fifty-five undergraduate, postgraduate, or professional violinists performed five randomly ordered 45-s musical excerpts of varying physical demands both before and after a randomly assigned 15-min, moderate-intensity cardiovascular, core muscle, musical (technical violin exercises), or inactive control warm-up protocol. Surface EMG data were obtained for 16 muscles of the trunk, shoulders, and right arm during each musical performance. Sound recording and perceived exertion (RPE) data were also obtained. Sound recordings were randomly ordered and rated for performance quality by blinded adjudicators. Questionnaire data regarding participant pain sites and fitness levels were used to stratify participants according to pain and fitness levels. Data were analyzed using two- and three-factor ANCOVA (surface EMG and sound recording) and Wilcoxon matched pairs tests (RPE)., Results: None of the three warm-up protocols had significant effects on muscle activity levels (P ≥ 0.10). Performance quality did not significantly increase (P ≥ 0.21). RPE significantly decreased (P < 0.05) after warm-up for each of the three experimental warm-ups; control condition RPE did not significantly decrease (P > 0.23)., Conclusion: Acute physiological and musical benefits from cardiovascular, core muscle, and musical warm-ups in skilled violinists are limited to decreases in RPE. This investigation provides data from the performing arts in support of sports medical evidence suggesting that warm-up only effectively enhances maximal strength and power performance.
