Abstract
The main objective of this study is to update the evidence related to the effectiveness of exercise and ergonomic interventions in the perception of shoulder pain intensity in workers considering the shoulder pain intensity and the minimum clinically important change in the analysis. The bibliographic search was conducted in seven databases (Cochrane, EMBASE, SciELO, PubMed, PEDro, Web of Science and Scopus) from March to April 2019. The study selection included randomized controlled trials (RCTs) involving workers with shoulder pain who underwent physical exercises, ergonomics, and combined interventions. To analyze the RCTs, the intensity of pain was divided into two subgroups < 3 and ≥ 3 (0–10 points scale). A total of 27 RCTs were included in the qualitative synthesis considering the perception scales of shoulder pain intensity and the PEDro scale score of assessment of RCTs quality and risk of bias. Within these, seven RCTs were included in the quantitative synthesis. The overall effectiveness of interventions was calculated using a meta-analysis method, and the associated measurement used as a mean difference. The meta-analysis revealed that exercise interventions in workers with shoulder pain > 3 presented a minimally clincially important difference (MCID), but with no difference in workers with pain < 3. The interventions with exercise in workers with pain ≥ 3 at baseline reported a beneficial effect in reducing shoulder pain intensity, and a MCID. However, there was no significant difference for workers with pain < 3 and the effects of ergonomic interventions are still uncertain to reduce shoulder pain in workers.
