Given the specific demands of dance, this case study aims to quantify the ability to coordinate knee movements with sounds and to analyze kinematics during the rehabilitation period. A female recreational street dancer participated in this study while undergoing rehabilitation after ACL reconstruction surgery. She performed knee flexion and extension movements to the beat of a metronome while standing, with both the movements and timing of the metronome beats recorded. Findings indicate that the muscle strength of her injured leg approached that of the uninjured side, suggesting steady rehabilitation progress. Although the range of knee joint angles did not differ between the injured and uninjured legs during the task, the injured knee exhibited less flexion and more extension. The participant was unaware of this increased extension in the injured leg. Additionally, the phase relationship between her rhythmic knee movements and the metronome beat changed unintentionally over the course of rehabilitation. Quantifying these unintentional changes in kinematics and their relationship to auditory beats can help establish appropriate criteria for a safe return to dance.</p>","PeriodicalId":18336,"journal":{"name":"Medical problems of performing artists","volume":"40 2","pages":"54-59"},"PeriodicalIF":0.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Music students, particularly, may experience challenges consistent with behaviors derived from their musician identity, such as prioritizing musical peruse over academic obligations and experiencing identity shifts during transitions in their musical training. However, existing research lacks consistency in defining musician identity. The lack of a well-defined conceptual framework for musician identity hinders the assessment of its changeability and the comparison of research findings. To address this issue, the present study aims to establish a conceptualization of musician identity through the validation of the Musician Identity Measurement Scale (MIMS) and the assessment of its factor structure. The study utilizes data from previous studies encompassing responses from 1,440 musicians (1,028 music majors and 412 non-music majors). The validation process included examining the MIMS' psychometric properties through exploratory structural equation modeling with robust weighted least squares estimation and evaluating measurement invariance by comparing configural and scalar models across sex and musician groups. Results support the MIMS as a valid 3-factor, reliable measure of musician identity and provide evidence for strong measurement invariance. The identified factor structure provides a foundation for future research exploring the musician identity, including how the three MIMS domains relate to various external correlates.</p>","PeriodicalId":18336,"journal":{"name":"Medical problems of performing artists","volume":"40 1","pages":"1-10"},"PeriodicalIF":0.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
