Biopsy samples from the erector spinae of persons with nonspecific chronic low back pain (NSCLBP) display a decrease in glycolytic muscle fibers.
Abstract
Low back pain (LBP) in Western Europe was classified as having the highest disability and overall burden among 291 studied conditions. For an extensive period of time evidence has accumulated related to morphological changes (e.g. atrophy and fat infiltration) of the paraspinal muscles in persons with LBP. Despite this evidence, there is limited knowledge on muscle fiber type composition of these muscles, and their relation to LBP.
