The purpose of this pilot study was to investigate the effects of trunk strength and stability training on body balance and low back and pelvis kinematics during gait in females. Six subjects volunteered to do 20 sessions of training. Data collection involved a qualitative pain grade test, low back stabilization tests, low back and pelvis kinematics, and body balance assessment. Results indicate the absence or decrease in the low back pain, and also an increase in the stabilization and strength of low back and pelvis complex. The 3-D kinematics showed statistically significant differences (p<0.05) when compared pre- to post-training. The body balance was improved as well as the range of motion (ROM) was improved for trunk rotation, pelvis inclination and low back flexion. The results suggest the influence of trunk strength and stability on low back and pelvis pain and kinematics as well as on body balance. Further studies with a larger sample and/or a control group must be conducted in an attempt to confirm this hypothesis.
这项初步研究的目的是调查躯干力量和稳定性训练对女性步态期间身体平衡以及腰背部和骨盆运动学的影响。六名受试者自愿参加了20节训练课程。数据收集包括定性疼痛分级测试、腰背部稳定测试、腰背部和骨盆运动学以及身体平衡评估。结果表明腰痛减轻或消失，同时腰背部和骨盆复合体的稳定性和力量增强。三维运动学显示，训练前后对比有统计学显著差异（p<0.05）。身体平衡得到改善，躯干旋转、骨盆倾斜和腰背部屈曲的活动范围（ROM）也得到改善。结果表明躯干力量和稳定性对腰背部和骨盆疼痛、运动学以及身体平衡有影响。必须进行更大样本和/或有对照组的进一步研究，以试图证实这一假设。
