(HealthDay News) – In patients with non-specific chronic low back pain (NSCLBP), postural training matched to the specific control impairment more effectively reduces pain and disability than generalized training, according to a study published in the Sept. 1 issue of Spine.

Liba Sheeran, PhD, from Cardiff University in the United Kingdom, and colleagues randomly assigned 49 patients with NSCLBP with a classification of flexion pattern and active extension pattern control impairment to either the classification system guided postural intervention (CSPI) or generalized postural intervention (GPI). Change in Roland-Morris Disability Questionnaire scores was the primary outcome. Evaluations were performed at baseline, immediately after one-to-one intervention, and after four-week home-based training.

The researchers observed a statistically and clinically significant reduction in disability and pain resulting from CSPI. There were only minimal changes in disability and pain with GPI. Following the one-to-one phase, there were significant reductions in absolute error in thoracic (sitting) and lumbar spine (standing) and constant error in lumbar spine (standing), although this was no longer significant at four weeks. There was no effect on trunk muscle activity by either intervention.

“Compared with minimal change in the GPI group, the CSPI produced statistically and clinically significant improvements in disability and pain outcomes and short-term improvements in some parameters of spinal repositioning sense in NSCLBP subgroups,” the authors write.
