[Purpose] Differences in scores on the Functional Movement Screen between patients with
chronic lower back pain and healthy control subjects were investigated. [Subjects and
Methods] In all, 20 chronic lower back pain patients and 20 healthy control subjects were
recruited. Chronic lower back pain patients and healthy controls performed the Functional
Movement Screen (deep squat, hurdle step, inline lunge, shoulder mobility, active straight
leg raise, trunk stability pushup, and rotary stability). The Mann-Whitney test was used
to analyze differences in Functional Movement Screen scores between the two groups.
[Results] Chronic lower back pain patients scored lower on the Functional Movement Screen
total composite compared with healthy control subjects. Chronic lower back pain patients
scored lower on Functional Movement Screen subtests including the deep squat, hurdle step,
active straight leg raise, and rotary stability tests. [Conclusion] The deep squat, hurdle
step, active straight leg raise, and rotary stability tasks of the Functional Movement
Screen can be recommended as a functional assessment tools to identify functional deficits
in chronic lower back pain patients.
