How do different standing positions affect trunk muscle activation in LBP-developers during prolonged standing?

ABSTRACT:

Background

Low back pain developers (PDs) are individuals at a high risk of developing low back pain (LBP), especially during prolonged standing. Understanding their characteristics is essential for devising effective preventive strategies. Prolonged standing has been associated with increased co-contraction of trunk muscles and elevated activity of the trunk extensor muscles. This study aims to examine the effects of using a normalized footrest height and altering arm positions on muscle activity in PDs.

Methods

Twenty-four female PDs, identified by a > 10 mm increase on the visual analog scale (VAS) during prolonged standing, were recruited. They were randomly divided into two groups: Group A used a footrest intermittently, while Group B used a footrest combined with chang
