To investigate the effect of exercise during pregnancy on the intensity of low back pain and kinematics of spine.
A prospective randomized study was designed. 107 women participated in an exercise program three times a week during second half of pregnancy for 12 weeks and 105 as control group. All filled a questionnaire between 17-22 weeks of gestation and 12 weeks later for assessment of their back pain intensity. Lordosis and flexibility of spine were measured by Flexible ruler and Side bending test, respectively, at the same times. Weight gain during pregnancy, Pregnancy length and neonatal weight were recorded.
Low back pain intensity was increased in the control group. The exercise group showed significant reduction in the intensity of low back pain after exercise (p<0.0001). Flexibility of spine decreased more in the exercise group (p<0.0001). Weight gain during pregnancy, pregnancy length and neonatal weight were not different between the two groups.
Exercise during second half of the pregnancy significantly reduced the intensity of low back pain, had no detectable effect on lordosis and had significant effect on flexibility of spine.
探讨孕期运动对腰痛强度及脊柱运动学的影响。
设计一项前瞻性随机研究。107名女性在妊娠后半期每周参加3次运动项目，持续12周，105名作为对照组。所有受试者在妊娠17 - 22周期间及12周后填写问卷，以评估其背痛强度。同时分别用软尺和侧弯试验测量脊柱前凸和柔韧性。记录孕期体重增加情况、妊娠时长和新生儿体重。
对照组腰痛强度增加。运动组运动后腰痛强度显著降低（p<0.0001）。运动组脊柱柔韧性下降更多（p<0.0001）。两组孕期体重增加、妊娠时长和新生儿体重无差异。
妊娠后半期运动可显著降低腰痛强度，对脊柱前凸无明显影响，对脊柱柔韧性有显著影响。
