Abstract
Objectives: To investigate the immediate effect of the Mulligan{u2019}s lumbar sustained natural apophyseal glides (SNAGs) on balance and pain in patients with chronic non-specific low back pain (CNSLBP). Subjects: 30 participants with CNSLBP were randomly allocated into two groups. The study group (n= 15) received a 2SNAGs3 on the affected lumbar level (s), and the control group (n=15) received the sham2SNAGs3. Methods: Outcome measures were balance assessment, pain level. They were measured by Biodex balance system (BBS) and visual analogue scale (VAS) respectively. Outcomes were measured before and immediately after the end of the intervention.Results: paired t-test revealed that there was a significant improvement in pain and balance after treatment regarding study group except for dynamic/8/single limb/ right and dynamic/4/single limb/right (p=0.0735, p=0.1643 respectively), while, the control group has shown no statistically significant difference in all pain and balance values except for static/both limbs and dynamic/8/single limb/left values (p=0.0116, p=0.0203 respectively). Unpaired t-test showed that lumbar SNAGs resulted in significant improvement in pain and static balance when compared to sham treatment(p=0.0046, p=0.0017 respectively). While there was no statistically significant difference between lumbar SNAGs and sham treatment regarding all dynamic balance tests that been applied during this study
