Abstract

          The purposes of this study were to compare pain, lumbar stability level and postural sway in anteroposterior (AP) and mediolateral (ML) between sling exercise and floor exercise in non-specific chronic low back pain (NCLBP). 

Twenty-six participants with NCLBP aged 20 to 50 years were divided into two groups; sling exercise (n=13), floor exercise (n=13). Both groups were received exercise 2 times/week for 4 weeks. The participants were performed 15 repetitions/set for 3 sets in each exercise. The modified isometric lumbar stability (MIST) was used to assess lumbar stability. The postural sway in the coronal and sagittal plane was evaluated by an accelerometer. Moreover, the pain intensity at the lower back was measured by a visual analog scale (VAS). The repeated two-way ANOVA was used for statistical analysis.

The results showed a significantly decreasing pain intensity and sway area in both groups after exercise (p<0.05). The reduction in VAS and sway area in AP and ML of the sling exercise group was significantly higher than the floor exercise group. The lumbar stability level was found a significant increase from baseline in both groups (p<0.05), but the sling exercise group provided higher improvement of lumbar stability than the floor exercise group. 

Both groups indicated a significant reduction of pain intensity and sway area in AP and ML as well as improved lumbar stability level. The findings suggest that the sling exercise is a greater reduction of pain intensity and sway area. Furthermore, the level of stability is more improved in the sling exercise.

QUESTIONS & ANSWERS

Prasan Tangyuenyongwatana (Participant)

Is it any instrument for measure the pain in this research instead of using visual analog scale?

Apinkarn Jaroenlarp (Presenter)

Thank you for your question. In this study, I just only use the visual analog scale (VAS) for measuring pain intensity. Because the VAS is a gold standard for pain measurement. Moreover, the VAS is a simple equipment and quick to administer. The participants have marked a point on the line that indicated the level of pain. This method may reduce the response-style bias associated with numeric scales.

What are the correlation of the sway area and postural stability?

Apinkarn Jaroenlarp (Presenter)

Thank you for pointing this out. I think this is an excellent question. However, the correlation between sway area and postural stability are not an objective in this study. In my opinion and from review literatures, postural sway or postural stability is the movement of the COM in a base of support. Postural stability is defined as the ability to maintain an upright position. Also,the sway area reflected the magnitude of body sway. If the participants had ability to maintain an upright position, may decrease of sway area. Therefore, there is a possibility of positive correlation  between sway area and postural stability.

Apinkarn Jaroenlarp (Presenter)

I sincerely apologize for having some answered incorrectly. There is a possibility of negative correlation between sway area and postural stability. If the patients had high postural stability, they had less of sway area.
