Prevalence and Predictive Factors of Active Myofascial Trigger Points Among Office Workers Using to Visual Display Terminals: A Cross-Sectional Study.

The study is a single snapshot. It cannot show whether the disability and low pain thresholds came before the trigger points or are a consequence of them. Only office workers from one town council took part, and they volunteered after an email invitation, which may mean they were more health-aware or more pain-aware than those who did not reply. More women than men took part, which the authors say could have influenced the prevalence figures and how the models behaved. Diagnosis relied on manual palpation, which varies between examiners; the authors used one experienced examiner throughout to keep it consistent. Psychosocial stress and workstation conditions were not recorded, so their contribution is unknown. The models were good at picking up people who had a trigger point but less good at ruling it out, so some people they flagged would not have had one.

The authors state they have no financial or non-financial disclosures to make in relation to this project. No funding source is reported in the text.

Do not read this as evidence that finding and treating trigger points will ease these workers' pain. No treatment was given and nobody was followed up, so the study cannot show whether disability and low pain thresholds cause the trigger points or result from them. The prediction models also flagged many people who did not have one.
