Effects of a concurrent exercise training program on low back and sciatic pain and pain disability in late pregnancy.

Abstract

The aim of the present study was to explore the influence of a concurrent exercise (aerobic + resistance) training program, from the 17th gestational week (g.w.) until birth on low back and sciatic pain, and pain disability. A total of 93 pregnant women divided into exercise (n=49) and control (n=44) groups followed a 60-min, 3 days/week, concurrent exercise training. Low back and sciatic pain were measured with a Visual Analogic Scale (VAS). The disability resulting from pain was assessed with the Oswestry Disability Index (ODI). Measures were performed at the 16th and 34th g.w. The exercise group increased 21.9 mm less the VAS low back (between-group differences (B): 95% CI: -33.6 to -10.2; p < 0.001) and 12.9 mm less the VAS sciatica score (between-group differences: 95% CI (B): -21.8 to -4.0; p=0.005) than the control group. Regarding the ODI questionnaire, the exercise group increased 0.7, 0.5, and 0.7 less than the control group in pain while sleeping (between-group differences (B): 95% CI: -1.4 to -0.01; p=0.025), pain while lifting weight (between-group differences (B): 95% CI: -0.9 to -0.01; p=0.016), and limitations of the social life due to pain (between-group differences(B): 95% CI: -1.3 to -0.06; p=0.032). Furthermore, the exercise group suffered 6.9% less pain than the control group in the ODI total score (between-group differences (B): 95% CI: -13.9 to 0.053; p=0.052). This concurrent exercise training program adapted to pregnant women improved pain compared to controls.
