The effects of sensorimotor training on proprioception and anticipatory postural adjustment of some trunk Muscle of subject with non-specific chronic low back pain

People with low back pain represent impaired anticipatory postural adjustments.The aim of this study was to investigate The effects of sensorimotor training on proprioception and anticipatory postural adjustment of the some trunk muscle of subject with non-specific chronic low back pain. The present study was a quasi - experimental study with a pretest-posttest design and control group. Twenty-four subjects with non-specific chronic low back painwere randomly assigned  in two control (n=12, mean age=44.83±1.52, mean Height=173.00±2.95, mean weight=77.50±3.55)and Experimental group (n=12, mean age=46.25±1.91, mean  Height=172.66±3.93, mean weight=75.50±4.12). The experimental group received sensorimotor training for eight weeks, Three times per week, for 45 minutes each session,in order to assess the proprioception, goniometer was used and change in Anticipatory postural adjustment, transverse abdominal / Internal oblique, external oblique and erector spinae muscles onset time relative to the shoulder flexion task was measured using surface electromyography. Data were analyzed by repeated measure ANOVA (α = 0.05). The results revealed significant difference between the pre-test and post-test scores of the experimental group in the proprioception and anticipatory postural adjustment of transverse abdominal / Internal oblique (p = 0.001), external oblique (p = 0.001) and Erector spinae (p = 0.001) but there was not observed such significant differences in control group. Sensorimotor training makes patients capable of learning how to adjust muscles, thereby improving muscle performance. So sensorimotor training  seems to be an effective intervention in the rehabilitation program for low back pain patients.
