Results: Five studies were included in the review. The number of participants varied from 4 to 293 participants.
Three of the five studies were Randomised Controlled Trials, one pre and post-test study was conducted and one
single case, multiple baselines (ABAB) study was done. Three studies were conducted in a garment factory, one in
an office environment and one with university students. All five studies found a reduction in self-reported
musculoskeletal pain immediately after the intervention. Bias was introduced due to poor randomization procedures
and lack of concealed allocation. Meta-analysis was not possible due to the heterogeneity of the data
(differing population, intervention and outcomes across studies).
