Risk of musculoskeletal injury in the back area on small industrial workers
Ade Gafar Abdullah, Isma Widiaty, Cep Ubad Abdullah in Medical Technology and Environmental Health, 2020
Ergonomics comes from the Greek word meaning “laws of work.”. It is also described as ‘fitting the task to man,’ which means to fit the human abilities and limitations to the work activities, tools, equipment, and work environment (Jagadish et al. 2018). Manual material handling, especially lifting, is one of the significant health and safety hazards in industry (Dormohammadi et al. 2012). Musculoskeletal diseases are a spectrum of health problems related to work activities involving muscles, nerves, tendons, bones, joints, and cartilage (Ramadhani et al. 2018). One major cause of musculoskeletal diseases (MSDs) is unergonomic working postures while doing working activities. Sain & Mena (2016) concluded that musculoskeletal disorders are the most common injuries related to poor ergonomics.
Myofascial Trigger Points, Sensitization, and Chronic Musculoskeletal Pain
Sahar Swidan, Matthew Bennett in Advanced Therapeutics in Pain Medicine, 2020
Remarkably, key tenets of Simons’ Integrated Trigger Point Hypothesis overlap with the role of muscle in MTrP development suggested by the Cinderella Hypothesis.32 Musculoskeletal disorder symptoms may arise from muscle recruitment patterns during sub-maximal level exertions with moderate or low physical load among office workers, musicians, and dentists, in which myalgia and MTrPs have been commonly reported.29 According to Henneman’s size principle, smaller type I muscle fibers are recruited first and de-recruited last during static muscle exertions. As a result, these “Cinderella” fibers are continuously activated and metabolically overloaded, in contrast to larger motor muscle fibers that spend less time being activated and do not work as hard. This property makes these fibers more susceptible to muscle damage and calcium dysregulation, key factors in the formation of MTrPs.33 Treaster et al. demonstrated that low-level static continuous muscle contractions during 30 minutes of typing induced the formation of MTrPs, supporting the Cinderella Hypothesis.34
Ankylosing spondylitis
John M. Saxton in Exercise and Chronic Disease, 2011
Patients with AS experience health benefits from exercise participation, such as reduced levels of pain and improved spinal mobility, self-reported physical functioning and global assessment of well-being. A systematic literature review of exercise studies reached this conclusion, but the reviewed studies had a number of methodological weaknesses (Dagfinrud et al., 2008). A frequent weakness in studies of complex health interventions is incomplete description of the exercise programme (Glasziou et al., 2008). Lack of thorough descriptions of the interventions used makes it difficult to reproduce the programme and to utilize possible positive findings. Recent research has shown that the implementation of positive findings is slow, and that a barrier for implementation may be clinicians’ ability to carry out the treatment on the basis of the information provided in published reports (Dopson et al., 2001; Glasziou et al., 2008). Furthermore, when descriptions are missing, it is difficult to ensure that the exercise programmes have sufficient dose, intensity and frequency to achieve specific physiological responses. Currently, physical activity and exercise rehabilitation are increasingly being considered as part of the treatment programme for several musculoskeletal diseases such as AS. As a dose-response relationship for exercise exists (as it does for pharmacological treatments), it is important that the prescription and monitoring of exercise as part of disease management is as specific and accurate as possible.
New Horizons of Knowledge in Intervertebral Disc Disease
Published in Journal of Investigative Surgery, 2021
Silvia Ravalli, Giuseppe Musumeci
Intervertebral disc disease (IVDD) refers to degenerative processes of the spine resulting in reduced shock-absorbing ability, which may ultimately lead to disc herniation and spinal cord compression. Back pain is associated with this condition, representing the clinical feature mostly frequently referred by the patients. The etiology, as for many musculoskeletal diseases, should be sought in environmental and genetic factors. These latter involve genes which are responsible for Collagen type IX and I, Aggrecan, Vitamin D receptor, while non-hereditary factors include primarily mechanical injuries, excessive loads and uneven weight distribution, as well as aging, obesity, chronic inflammation, and work-related risk factors like long sitting sessions, e.g. while driving, or non-ergonomics office equipment [1]. It is estimated that more than 200 million cases of lumbar degenerative spine disease occur, each year, worldwide, significantly contributing as a major cause of disability and socio-economic burden [2].
Sports and exercise medicine clinic in public hospital settings: a real-life concept and experiences of the treatment of the first 1151 patients
Published in Postgraduate Medicine, 2023

Since the start of autumn 2016 to end-December 2021, the SECM has treated 1151 patients (Figure 1). The patient flow rose in the first years, reaching the patient visit numbers. Table 1 lists the 20 most common diagnoses of our 2016–2020 patients. Overweight is present in approximately two-thirds of all patients, followed by (co-existing) sleep apnea, hypertension, non-insulin dependent diabetes, and asthma. The first musculoskeletal disorder in which symptoms are worsened by physical inactivity and attenuated with exercise – osteoarthritis – is ranked sixth. Cardiovascular disease-related diagnoses are less common than expected, as a separate physiotherapy-led rehabilitation protocol for cardiac patients already exists in the hospital district.
Evaluation of the biodynamic response of the hand–arm system and hand-tool designs: a brief review

The working frequency measure was limited to 8–1000 Hz to assess the vibration injury. Vibrations in the frequency range of 6–20 Hz were measured to be more harmful, but the consequence gradually decreased as the frequency increased (ISO 2001). Organized, self-reported questionnaires to access the injuries caused due to vibration exposure were developed [56]. Their report consists of the screening method to decide musculoskeletal diseases due to the experience of hand-transmitted vibration. On the other hand, both subjective and objective methods are combined to calculate the health effects due to hand-transmitted vibrations [63]. Subjective measures try to evaluate HAVS occurrence through the questionnaire method [57,58]. Subjective measurements are influenced by the worker’s quality of life, health condition, experience, perceptions and comfort ability [61,65]. Objective measurements are not influenced by the perception of humans, provide numbers and are repeatable [34].
