Abstract
PURPOSE: Musculoskeletal disorders can be common in wind and string instrumentalists. The musical gesture technique associated to musical performance can promote an asymmetrical isometric contraction with the hyperactivity of specific muscular groups and the overload of articular surfaces which can cause discomfort or pain. The aim of this investigation was to assess specific anatomical regions of interest within the cranio-cervico-mandibular complex in order to determine and evaluate the presence of muscular hyperactivity associated to musical performance. METHODS: An infrared imaging camera, FLIR®, was used to record the regions of interest in wind (n = 48) and string instrumentalists (n = 29). Bilateral temperature differences were considered as thermal asymmetries with a conventional threshold of 0.3 ºC to distinguish pathological from healthy states. The regions of interest (ROI) were the anterior triangle of the neck, the sternocleidomastoid and trapezius muscles regarding the postural and stabilizing muscles of the head and neck. On the orofacial region, the anatomical sites were the anterior temporal muscle, the masseter muscle and the temporomandibular joint. A Pearson chi-square test was performed to compare the assessed areas. RESULTS: Between 30-37% of all participants showed ROI in an asymmetric pattern. The most affected sites were the temporal muscle and the TMJ for both groups. The anterior triangle of the neck showed statistical differences (p = 0.044) between string and wind instrumentalists, while the temporal (p = 0.034) and trapezius muscle (p = 0.028) when comparing large and small mouthpieces of brass instruments. Although female participants showed a higher prevalence of asymmetrical patterns regarding the ROI, no statistical differences were found between genders. CONCLUSIONS: Infrared thermography exhibited significant differences between wind and string instruments within the CCMC. Regarding the issue of occupational health in performing arts, it is an advantage being able to quantify asymmetrical patterns sites of the CCMC to understand the underlying physiological responses to repetitive movements, overloading and muscular hyperactivity that occur during musical performance.
