Objectives: To compare the performance of cervical stabilizer muscles using the craniocervical flexion test (CCFT) among individuals with subacute, chronic, and asymptomatic low back pain (LBP) conditions. Methods: Individuals with subacute (N = 23) and chronic LBP (N = 23) with their age- and gender-matched controls (N = 30) participated in this study. All recruited participants were required to perform the CCFT. The activation score (AS) and the performance index (PI) were recorded by an assessor who was blinded to the group of participants. Results: Approximately, 74% of subacute LBP participants and 60-65% of chronic LBP participants obtained abnormal AS and PI. AS was significantly lower in participants with subacute (P = 0.0002) and chronic LBP (P = 0.0009) than the control group. Likewise, the PI was significantly lower in participants with subacute (P = 0.0002) and chronic LBP (P = 0.0036) than the control group. Participants in the subacute LBP group showed significantly greater percentages of abnormal responses on the AS (P < 0.0001) and the PI (P = 0.0001) than the control. Discussion: Abnormal performance of cervical stabilizer muscles using the CCFT was demonstrated in a high proportion of participants with LBP. The findings highlight the plausible association in muscle control between cervical and lumbar stabilizers. Level of Evidence: 2b.
