The relation between psychosocial working conditions and work-related musculoskeletal complaints

Increased muscle tension can result in a number of pain syndromes related to trigger point formation, strains and myofascial pain syndromes. The trapezius muscle, commonly involved in neck/shoulder upper limb disorders, may be more sensitive to emotional stress-related factors, as it is innervated via both the cervical spine and the accessory cranial nerve. It has been suggested that it may have an evolutionary role in communicating a stress response by hunching the shoulders or in assuming a protective posture when under perceived attack (Cailliet, 1991).
Investigating the impacts of working at home among office workers with neck pain on health status, depression and sleep quality during the COVID-19 pandemic
Published in International Journal of Occupational Safety and Ergonomics, 2023
The job scope of office workers mostly includes computer use, interviews, presentations and phone calls. It includes prolonged static posture and repetitive writing and reading activities in inappropriate positions. According to studies, a person spends three-quarters of her/his working time sitting. Decreased physical activity and working at the computer for a long time cause occupational safety problems and constitute an important risk factor for musculoskeletal systems [5]. The most common work-related musculoskeletal disorders (MSDs) were reported as lower back pain (LBP) and neck and shoulder pain [6]. Although the prevalence of neck pain is 12–34% in the general population, it has been reported that the 12-month prevalence of those working at a computer exceeds 50–60% [5]. Moretti et al. [7], in their study of 51 mobile office workers, found that 41.2% of them had LBP and 23.5% of them had neck and other pains. Myofascial pain syndrome is one of the neck pain reasons. Myofascial pain syndrome is a chronic musculoskeletal pain characterized by taut bands of muscles which are painful to palpation of muscles. The taut bands are also defined as trigger points. The exact aetiology is unknown. Postural factors, ergonomic features, overuse of the muscles or microtraumas may be the reasons [8]. A review about myofascial trigger points emphasized that myofascial trigger points may be related to MSDs, especially as a source in workplaces [9].

The aggravation associated with back pain can range from a dull, constant ache to sudden, sharp pains. It comes from a variety of different causes and affects men and women of different ages. The pain varies according to the postures and the physical activities and many reports have suggested that myofascial syndrome is a very common cause of LBP (Sharan, Rajkumar, Mohandoss, & Ranganathan, 2014; Simons & Travell, 1983). Myofascial pain syndrome is defined as pain that originates from myofascial trigger points in skeletal muscle. It is prevalent in regional musculoskeletal pain syndromes, either alone or in combination with other pain generators.

Myofascial pain syndrome (MPS), also known as myofasciitis, which is the pain due to aseptic inflammation of muscles and fascia that stimulates small nerves on the body surface.[1] MPS is characterized by multiple trigger points (TP) and muscle tension in the muscles and fascia of different parts of the body. The TPs are sensitive to stimulation, and prone to cause local pain and involved pain.[2,3] MPS can occur at any age, and its incidence can reach 30%–93%. The pathogenesis of MPS is not yet clear, which render the treatment of the MPS disease.
