Abstract
Background and Purpose. Improving functional performance in patients with chronic low back pain is of primary importance. The purpose of this study was to examine the effects of 2 proprioceptive neuromuscular facilitation (PNF) programs on trunk muscle endurance, flexibility, and functional performance in subjects with chronic low back pain (CLBP). Subjects. Eighty-six women (40.2±11.9 [X̅±SD] years of age) who had complaints of CLBP were randomly assigned to 3 groups: rhythmic stabilization training, combination of isotonic exercises, and control. Methods. Subjects trained with each program for 4 weeks with the aim of improving trunk stability and strength. Static and dynamic trunk muscle endurance and lumbar mobility were measured before, at the end of, and 4 and 8 weeks after training. Disability and back pain intensity also were measured with the Oswestry Index. Results. Multivariate analysis of variance indicated that both training groups demonstrated significant improvements in lumbar mobility (8.6%–24.1%), static and dynamic muscle endurance (23.6%–81%), and Oswestry Index (29.3%–31.8%) measurements. Discussion and Conclusion. Static and dynamic PNF programs may be appropriate for improving short-term trunk muscle endurance and trunk mobility in people with CLBP. [Kofotolis N, Kellis E.
