摘要：Aim. Acute low back pain (ALBP) is a major factor of disability among workers, causing absence from work and an increased medical care cost. The purpose of this study was to evaluate maximal isometric strength (MIS) differences between acute low back pain subjects with prolonged sitting jobs and demanding physical work jobs, for extension with pelvic stabilization (EPS) and flexion with pelvic stabilization (FPS). Methods. Maximal isometric torque for EPS and FPS was measured at two positions (0 and 30-degree flexion angles) on 56 men. Subjects were assigned in four groups, two with ALBP, the first (n=14) with prolonged sitting jobs and the second (n=14) with demanding physical work jobs and the other two (controls) without ALBP, the first (n=14) with prolonged sitting jobs and the second (n=14) with demanding physical work jobs. Results. ALBP subjects with prolonged sitting jobs and with demanding physical work jobs described lower MIS in both EPS and FPS, in both angles, relative to controls (p<0.05). ALBP subjects with prolonged sitting jobs had lower values of MIS in both EPS and FPS, in both angles, than ALBP subjects with demanding physical work jobs (p<0.05). Conclusions. These data indicate that ALBP has impaired both ALBP groups in MIS production, than controls. Demanding physical work for ALBP subjects is a direct factor for greater MIS production, than ALBP subjects with prolonged sitting jobs, despite the presence of ALBP.
