Examining spinal mobility, aerobic capacity and functional movement in patients with non-specific chronic low back pain: a case-control study

Abstract

Background/Aims The increasing cost and incidence of non-specific chronic low back pain means that many physiotherapists are reconsidering the management of this condition. The primary aim of this study was to examine spinal mobility, aerobic capacity and functional movement screen in patients with non-specific chronic low back pain. The secondary aim was to determine the factors affecting the disability level. Methods Participants aged between 18–65 years old diagnosed with non-specific chronic low back pain for >3 months were recruited as a study group, while those without low back pain in the last 3 months were the control group. Outcome measures included the Functional Movement Screen for functional movement, the 2-Minute Step Test for aerobic capacity, the Spinal Mouse for spinal mobility and Oswestry Disability Index for disability level. Results A total of 60 participants, 30 people with non-specific chronic low back pain (42.7 ± 10.6 years) and 30 people without low back pain (42.0 ± 7.3 years), were included in this study. There were statistically significant differences in the total sagittal plane angle (P<0.001), total frontal plane angle (P=0.03), 2-Minute Step Test (P<0.001) and Functional Movement Screen (P<0.001) scores between groups. Pain and aerobic capacity explained 42.4% of the variance as determinants of disability in the study group. Conclusions In people with non-specific chronic low back pain, sagittal and frontal plane range of motion and aerobic capacity were decreased and their functional movements were impaired. Pain intensity and aerobic capacity affect the disability level of non-specific chronic low back pain. Implications for practice People with non-specific chronic low back pain have reduced spinal mobility, aerobic capacity and functional movement. These parameters should be included when determining treatment programmes. At the same time, the level of disability can be reduced by decreasing pain intensity and increasing aerobic capacity of people with low back pain.
