Prolonged standing work and intense training are associated with MSDs and muscle fatigue is considered a precursor to MSDs (Garcia, Laubli, & Martin, 2015; Hadrevi et al., 2019). However, the myriad of underlying possible reasons muscle fatigue discussed in the following section makes epidemiological studies difficult. Work‐related muscle pain (myalgia) is considered a public health problem causing otherwise healthy individuals to end up on sick leave (Holtermann, Hansen, Burr, & Sogaard, 2010). Neck pain is one of the more common MSDs, with over 30% of individuals experiencing some degree of discomfort in the neck over a lifetime (Cohen, 2015; Cote, Cassidy, & Carroll, 1998). Most episodes of acute neck pain will resolve with or without treatment, but nearly 50% of individuals will continue to experience some degree of pain or frequent occurrences. A “tissue fibrosis” hypothesis is supported by clinical studies examining biopsies from patients with chronic MSDs (Dennett & Fry, 1988; Ettema, Amadio, Zhao, Wold, & An, 2004; Hirata et al., 2005).
