Age-dependent flexion relaxation phenomenon in chronic low back pain patients.
Authors
Zhang T, Firouzabadi A, Yang D, Liu S, Schmidt HAbstract
The flexion relaxation phenomenon (FRP) is characterized by suddenly reduced paraspinal muscle activity during full flexion. Previous studies showed significant differences in FRP and flexion angles in chronic low back pain (cLBP) patients compared to individuals without back pain (no-BP). However, the relationship between FRP and flexion angles remains insufficiently understood in older populations. Thus, this study investigated the relationship between FRP and flexion angles concerning to the age and presence of cLBP.
