They can also suffer muscle contractures that are produced by the combination of repetitive exercise and sudden changes in temperature (1). The objective of this study was to describe ergonomically the postural overload of professional drivers of the public transport “Tomebamba”, using the Rapid Entire Body Assessment REBA method. The present research descriptive counted whith the participation of 52 drivers who work in the Tomebamba Company S.A.
