Assessment of cervical range of motion, cervical core strength and scapular dyskinesia in violin players

摘要

Background. Playing the violin can lead to asymmetric postures which can affect the cervical range of motion, cervical core strength and scapular stability. Objective. The objective of the study was to assess the cervical range of motion, cervical core strength and scapular dyskinesia in violin players and non-players of the same age group. Methods. An inclinometer was used to assess the cervical range of motion, pressure biofeedback was used to assess cervical core strength and scapular dyskinesia was also assessed in 30 professional violin players (18-40 years) compared with 30 age-matched non-players. Analysis was done using an unpaired t test. Results. Significant change was seen with respect to extension (p = 0.051), cervical core strength (p = 0.005), right (Rt) superior angle 0 degrees (p = 0.004), Rt superior angle 45 degrees (p = 0.015) and Rt inferior angle 90 degrees (p = 0.013). Conclusion. This study shows a significant difference in extension range of motion and cervical core strength of violin players. Also, there was scapular dyskinesia seen at 0 degrees and 45 degrees right-side superior angle of the scapula and 90 degrees right-side inferior angle of the scapula.
