This study was funded, in part, by a Small Faculties Grant from the University of Alberta. Physical therapists have reported an increased incidence of low back pain (LBP) in female field hockey (FH) players, commonly accompanied by decreased trunk range of motion (ROM) and strength. The purpose of this study was to compare lumbosacral sagittal ROM and isokinetic trunk strength in three groups of women: 1) FH athletes with a history of chronic LBP, 2) pain-free FH athletes, and 3) an age-matched, healthy nonathletic control group. Photographs (35 mm) of subjects wearing spinal motion markers were used to determine the limits of lumbosacral saggital ROM in standing. Eccentric and concentric isokinetic trunk flexion and extension torques were measured in sitting through 60 degrees of trunk movement using a Kin-Com dynamometer set at 60 degrees /sec. The ANOVA showed that the pain group had 12 degrees and 18 degrees less extension (p < .01), as well as 18 degrees and 24 degrees less total ROM (p < .001) than the pain-free and control groups, respectively. Only peak (p < .001) and average (p < .03) eccentric extension torques were weaker in the pain group than in the nonathletic control group. These results suggest that physical therapists should perform preseason screening of trunk strength and lumbosacral ROM. In-season trunk extension stretching and strengthening is needed in the training regimes of these athletes. J Orthop Sports Phys Ther 1992;16(3):129-135.
本研究部分由阿尔伯塔大学小型教员资助。物理治疗师报告称，女性曲棍球运动员中腰痛（LBP）的发病率增加，通常伴有躯干活动范围（ROM）和力量下降。本研究的目的是比较三组女性的腰骶矢状面 ROM 和等速躯干力量：1）有慢性 LBP 病史的曲棍球运动员，2）无疼痛的曲棍球运动员，3）年龄匹配的健康非运动员对照组。使用脊柱运动标志物拍摄的受试者照片用于确定站立时腰骶矢状面 ROM 的极限。使用 Kin-Com 测力计在 60 度/秒的速度下通过 60 度的躯干运动在坐姿下测量偏心和向心等速躯干屈伸扭矩。方差分析表明，疼痛组的伸展幅度比无痛组和对照组分别小 12 度和 18 度（p<.01），总 ROM 小 18 度和 24 度（p<.001）。仅在疼痛组中，峰值（p<.001）和平均（p<.03）的偏心伸展扭矩均弱于非运动员对照组。这些结果表明，物理治疗师应在赛前对躯干力量和腰骶 ROM 进行筛查。在这些运动员的训练计划中，需要进行赛季中躯干伸展拉伸和加强。J Orthop Sports Phys Ther 1992;16(3):129-135。
