The purpose of this study was to investigate the influence of lumbar stabilization exercise order on muscle activity of erector spinae and low-back pain in patients with chronic low-back pain.
Thirty patients with chronic low-back pain were randomly assigned into two groups based on the order of exercises performed during training session : a group that performed ADIM exercise first and progressed to Sling exercises(ADIM-Sling); while a second group performed the opposite sequence and started with Sling exercise and progressed ADIM exercise(Sling-ADIM). Two session of lumbar stabilization exercise were conducted per week. ADIM exercise was performed 10-sec holding of ten repetitions with 10-sec rest intervals between sets. Sling exercises were performed for ten sets of four repetitions with 10-sec rest intervals between sets. The degree low-back pain was measured by using VAS, ODI and muscle activation of erector spinae was measured by electromyography when sitting to standing on the chair of 40cm. After 4-week break, they were measured again.
The changes in groups were compared before and after exercise. As a result, in both ADIM-Sling group and Sling-ADIM group, VAS, ODI, were significantly decreased (p<.05), and muscle activation of erector spinae were significantly increased (p<.05). But asymmetric index of erector spinae were not significantly changed (p>.05)
The changes between groups were compared before and after exercise. As a result, VAS, ODI, muscle activity and asymmetric index not significantly changed.(p>.05)
Given the above results, even if not effective in the muscle asymmetry improvement, lumbar stabilization exercise for patients with chronic low back pain is thought to be able to be presented as an exercise method which is effective in an increase in muscle activation of erector spinae and relief of back pain regardless of exercise order.
