Abstract

Low back pain is the major clinical refare and socio-economic problem in most countries. This study designed to compare the effect of motor control exercises and PNF exercises on postural control, strength, endurance, and proprioception in women with non-specific chronic low back pain.
Methods: 45 women with non-specific chronic low back pain were selected by convenience sampling and randomly divided into three groups of 15 (motor control exercises, PNF, control group). Pre-test included posture control, trunk flexor and extensor muscle strength, trunk muscle endurance and proprioception using Y balance, dynamometer, McGill and Goniometer tests, respectively. The subjects of the experimental groups performed the training program for 8 weeks. Then the post-test was performed. Paired t-test and analysis of covariance at the significance level of 0.05 were used to collect data for data analysis.
Results: The results showed that motor control and PNF exercises improved proprioception, postural control, endurance, trunk flexor and extensor muscles strength. Also, there was no significant difference between groups in these factors.
Discussion: Motor control and PNF exercises are effective in improving the proprioception, postural control, endurance, trunk flexor and extensor muscles strength in women with non-specific chronic LBP and both training methods are effective likely.
