Background Non-communicable diseases pose a significant health threat worldwide. Of those diseases, musculoskeletal diseases are most responsible for a significant portion of occupational injuries in all job-sectors, including the musical sector. Musicians are prone to suffering from musculoskeletal injuries, more so than other populations. These injuries are termed playing-related musculoskeletal diseases (PRMDs). There are several risk factors associated with acquiring PRMDs including being of the female gender, age, and the type of instrument played. While most literature on musicians’ has been documented in countries abroad, there is a paucity of literature looking at the risk factors and attributes of African, and specifically South African, musicians. This is notable, as African musicians may have different characteristics to their international counterparts. The aim of this research was to examine orchestral musicians in Kwa Zulu-Natal from all sections of the orchestra to determine the prevalence of musculoskeletal injuries and the potential risk factors for these injuries, as well as their musculoskeletal injury profile. Methodology This study was a quantitative, cross-sectional descriptive study based on a self administered questionnaire. The questionnaire was piloted electronically and the necessary alterations were made. The final questionnaire was administered to members of 2 orchestras in Kwa Zulu-Natal, namely the Pietermaritzburg City Orchestra (25 members) and the Durban City Orchestra (30 members), making the targeted sample 55 musicians in total. All musicians who met the inclusion criteria were invited to participate in the study. The anonymously completed questionnaires were placed into marked boxes after completion to ensure musician anonymity. The data was analysed using IBM SPSS version 28. Association between specific risk factors and 12-month prevalence of MSK was assessed using Fisher’s exact 2-sided tests for categorical risk factors, and t-tests for continuous risk factors. A p-value of <0.05 was taken as statistical significance. Results Of the 55 musicians targeted, 30 of them participated, resulting in a response rate of 54.5%. Majority of the respondents were female (n=20). The data showed that the annual prevalence of PRMDs in the two orchestras was 46.7%. The point and one month prevalence were both 40%. The most injured section of the orchestra were the strings, followed by the woodwind section. The string section also reported the highest number of average affected areas in the orchestra (n=4). The most frequently injured anatomical sites of the body were the shoulders and wrists. There was no statistical significance found between the risk factors and injuries acquired. However, the results showed that females were injured more than the males (55%). Most of the respondents that reported musculoskeletal injury fell within the 18-24 age range and majority of the injured musicians fell in the overweight BMI body category. Most of the music teachers and the single career musicians in the study reported suffering from PRMDs and playing instruments for more than 16 hours a week on average. Conclusion The prevalence of playing-related musculoskeletal disorders among musicians was relatively high among the orchestral musicians in Kwa Zulu-Natal. Though not statistically significant, factors such as instrument played, age, and female gender were the factors that had the greatest influence on injury rates. The pain experienced was mild in nature and felt worse after playing their instruments. While the pain did not affect their activities of daily living, it did cause a few to change their way of playing or stop playing entirely for a period of time due to their pain. Majority of the players were aware of musician’s playing related health problems, and acknowledged that they are a problem, but none of them had received formal methods of education regarding them. The COVID-19 pandemic was a phenomenon that also affected the musicians in various ways
