观察。提供不同年龄、不同种族女性腰椎屈伸功能的正常值。脊柱活动范围（ROM）是AMA指南中用于估计损伤程度和后续赔偿权利的标准之一。研究表明，脊柱ROM随年龄、性别和可能的种族/民族而变化，但不存在针对不同年龄和种族/民族的适当标准值。达拉斯的库珀研究所招募了一批自由生活的妇女进行妇女伤害研究。最初，917名年龄在20岁至83岁之间的女性（M = 52 ± 13）接受了骨科检查，包括使用电子倾斜仪测量腰椎屈曲和伸展。分别在完全伸展和屈曲位置进行测量。这消除了最初的休息姿势的影响，并被称为“极端的运动”（EOM），而不是ROM。年龄和种族组进行了比较，使用2因素多变量方差分析（MANOVA），然后事后检验。计算人种（白色，N = 619，非裔美国人，N = 147）和年龄组（年轻，20-39岁，n = 126;中年，40-59岁，n = 412;老年，≥60岁，n = 228）的平均值（±SD）。非裔美国女性的腰椎伸展度（60.1°）显著高于（P < 0.05）白色女性（52.6°），但屈曲度无差异（分别为15.2°和17.0°）。青年组眼外展角（61.6°）大于中年组（56.6°）和老年组（50.8°）（P < 0.05）。中、老年组伸展运动差异有显著性。青年组眼外肌角（20.1°）大于中年组（15.2°）和老年组（12.8°）（P < 0.05）。中老年组屈曲度差异无统计学意义。白色和非洲裔美国妇女的腰椎伸展的标准值是不同的。不同年龄组的腰椎屈曲和伸展值不同。不同种族和年龄组的妇女应采用不同的标准来估计损伤程度。
Observational. To provide normative values of lumbar flexion and extension for women of different age and racial groups. Spinal range of motion (ROM) is one of the AMA Guides criteria used to estimate level of impairment and subsequent compensation entitlement. Studies show that spinal ROM varies with age, gender, and possibly race/ethnicity, but adequate normative values for different age and racial/ethnic groups do not exist. A cohort of free-living women was recruited for the Women's Injury Study at The Cooper Institute in Dallas. Originally, 917 women between the ages of 20 and 83 (M = 52 ± 13) underwent an orthopedic examination including lumbar spine flexion and extension measurement using an electronic inclinometer. Measurements were taken in the fully extended and flexed positions, respectively. This removes the influence of initial resting posture and is termed “extreme of motion” (EOM) as opposed to ROM. Age and racial groups were compared using a 2-way multivariate analysis of variance (MANOVA) followed with post hoc tests. Means (±SD) were calculated for racial (white, N = 619, African-American, N = 147) and age groups (young, 20–39 years, n = 126; middle, 40–59 years, n = 412; older, ≥60 years, n = 228). Lumbar extension for African-American women (60.1°) was significantly greater (P < 0.05) than for white women (52.6°), but flexion was not different (15.2° and 17.0°), respectively. Extension EOM for the young group (61.6°) was greater (P < 0.05) than the middle (56.6°) and older (50.8°) groups. Extension difference between the middle and older groups was significant. Flexion EOM for the young group (20.1°) was greater (P < 0.05) than the middle (15.2°) and older (12.8°) groups. The difference in flexion between the middle and older groups was not significant. Normative values of lumbar extension are different for white and African-American women. Values for lumbar flexion and extension are different between age groups. Different criteria should be used to estimate impairment level in women of different racial and age groups.
