Responsiveness of hand-held dynamometry for measuring changes in trunk muscle strength in people with chronic low back pain.

ABSTRACT:

Objective

To assess the responsiveness of a hand-held dynamometer (HHD) in evaluating changes in trunk isometric strength in people with chronic low back pain (LBP).

Background

Reduced trunk muscle strength has been associated with pain incidence and severity in people with chronic LBP. Trunk muscle strength is an important functional outcome that is measured in clinical practice and research. However, the responsiveness of clinical tools such as HHD for measuring changes in trunk muscle strength remains underexplored.

Methods

Maximum isometric trunk strength was measured using both a HHD and an isokinetic dynamometer (ID) in 21 participants with chronic LBP both before and after 6 weeks of progressive trunk resistance exercises. Effect sizes (ES) and standardised res
