Introduction: playing the instrument in different groups of society is increasing day by day. Therefore, it seems necessary to pay attention to musculoskeletal imbalances and their problems in musicians. Methods: 90 instrumentalists, including 26 wood wind players (age: 28.46 ± 4.62 years, BMI: 26.59 ± 2.11), 37 string players (age 28.18 ± 7 years, BMI: 24.92 ± 3.60), and 27 percussionists (age: 31.88 ± 6.6 years, BMI: 24.95 ± 3.32) Were selected to participate in this study. Upper and lower extremities were assessed. For statistical analysis ANOVA, Scheffe and Kruskal-Wallis statistical tests were performed in SPSS version 16 with a significance level of 0.05. Results: The results of this study did not show significant differences between the degree of musculoskeletal imbalances of kyphosis and lordosis between the study groups (p˃0.05). Results in musculoskeletal imbalances of scoliosis(Sig = 0.001), forward head(Sig = 0.001), uneven shoulder(Sig = 0.001), torticollis(sig = 0.001), scapular dyskinesia (Sig = 0.006) were showed the significant differences between the groups(p˂0.05). Conclusion: According to the results, some musculoskeletal imbalances in the group of wood wind instrumentalists showed a higher intensity and prevalence. These variabilities between different groups of musicians indicate different physical and postural needs to play different instruments.
