Abstract

Purpose: This study aimed to compare functional capacity tests between individuals with and without chronic non-specific low back pain and to investigate the effects of demographic data on functional capacity tests.

Methods: Thirty individuals with chronic non-specific low back pain (CNSLBP) and thirty healthy individuals underwent three functional capacity tests comprising functional reach test (FRT), five-time sit to stand test (5 TSST), and two-minute step test (2 MST). CNSLBP were assessed in pain intensity using a visual analog scale (VAS) and disability level using the modified Oswestry disability questionnaire (MODQ) Thai version.

Results: The results found significant differences in five-time sit to stand and two-minute step tests between individuals with chronic non-specific low back pain and healthy individuals. The mean differences between healthy and CNSLBP for the 5 TSST were -3.24 seconds (95% CI=-4.47--2.02) and for the 2 MST they were 13.13 steps (95% CI=2.62-23.64). Age significantly influenced the 5 TSST (P=0.004) and 2 MST (P=0.008), while gender (P=0.028) and height (P=0.002) affected the FRT.

Conclusion: Individuals with chronic non-specific low back pain had lower functional capacity assessed by five-time sit to stand and 2-minute step tests compared to healthy individuals, and the therapeutic programs were emphasized. With increasing age, the 5 TSST and 2 MST would both be declined.

Keywords: five-time sit to stand; functional reach; physical examination; two-minute step.
