Abstract
Work related musculoskeletal disorders are a major concern for public health and pain is the most important symptom. The aim of this study was to verify the effectiveness of workplace exercises to control musculoskeletal pain and its frequency, intensity, duration and type of exercises used. The search was conducted systematically in Medline, Pubmed, Embase, Bireme, Web of Knowledge and Pedro databases. The keywords "workplace", "exercise" and "musculoskeletal disorders" were used combined. Randomized control trials which performed worksite exercises were selected and the studies were assessed by their methodological soundness. Ten articles were selected which investigated the resistance training, cardio respiratory exercises, Pilates, stretching, postural orientation and exercises for relaxation. Workplace resistance training performed at 70-85% RM, three times a week for 20 minutes promotes reduction of the pain in shoulders, wrists, cervical, dorsal and lumbar spine. However, there is no consensus regarding the total duration of the intervention for the decrease of musculoskeletal pain in these regions. Level of Evidence I, Therapeutic Studies Investigating the Results of Treatment, Systematic Review of RCTs (Randomized and Controlled Clinical Studies).
Highlights
The work-related musculoskeletal disorders (WRMD) are a worldwide public health problem and often can lead to temporary or permanent disability at work.[1]
Studies that investigated participants with musculoskeletal pain were included; with intervention containing exercises performed individually or in a group with a structured program; exercises performed in the workplace; articles in English and Portuguese; documents and full text articles freely available
Exclusion criteria were studies that evaluated the effect of changes in risk factors, occupation and other factors that triggered musculoskeletal pain; intervention programs without monitoring by experienced profissional; intervention associated with supplementation or medication program; review articles, letters to the editor, comments, study protocols, case studies, theses and dissertations; studies performed over 10 years ago
Summary
The work-related musculoskeletal disorders (WRMD) are a worldwide public health problem and often can lead to temporary or permanent disability at work.[1] They are considered multifactorial, complex and of insidious nature. The effects of exercise performed in the occupational environment regarding pain improvement are inconclusive.[9] The aim of this study was to verify the effectiveness of exercise programs in the occupational environment in controlling musculoskeletal pain. It aimed to verify the influence of the type of exercise, intensity, frequency and duration of the training for reducing musculoskeletal pain
