Frontal- and transverse-plane kinematics have been prospectively identified as risk factors for running-related injuries in females. The Running Readiness Scale (RRS) may allow for clinical evaluation of these kinematics.
To determine the reliability and validity of the RRS as an assessment of frontal- and transverse-plane running kinematics.
Cross-sectional study.
University research laboratory.
A total of 56 novice female runners (median [interquartile range] age = 34 years [26-47 years]).
MAIN OUTCOME MEASURE(S): We collected 3-dimensional kinematics during running and RRS tasks: hopping, plank, step-ups, single-legged squats, and wall sit. Five clinicians assessed RRS performances 3 times each. Interrater and intrarater reliabilities of the total RRS score and individual tasks were calculated using the intraclass correlation coefficient and Fleiss κ, respectively. Pearson product moment correlation coefficients between peak joint angles measured during running and the same angles measured during RRS tasks were computed. Peak joint angles of high- and low-scoring participants were compared.
Interrater and intrarater reliabilities of assessment of the total RRS scores were good (intraclass correlation coefficients = 0.75 and 0.80, respectively). Reliability of assessing individual tasks was moderate to almost perfect (κ = 0.58-1.00). Peak hip adduction, contralateral pelvic drop, and knee abduction during running were correlated with the same angles measured during hopping, step-ups, and single-legged squats (r = 0.537-0.939). Peak knee internal rotation during running was correlated with peak knee internal rotation during step-ups (r = 0.831). Runners who scored high on the RRS demonstrated less knee abduction during running (P ≤ .01).
The RRS may effectively assess knee abduction in novice runners, but evaluation criteria or tasks may need to be modified to effectively characterize pelvic and transverse-plane knee kinematics.
额状面和横断面上的运动学已被前瞻性地确定为女性与跑步相关损伤的危险因素。跑步准备量表（RRS）可用于这些运动学的临床评估。
确定 RRS 作为评估额状面和横断面上跑步运动学的可靠性和有效性。
横断面研究。
大学研究实验室。
共 56 名新手女性跑步者（中位数[四分位数范围]年龄=34 岁[26-47 岁]）。
我们在跑步和 RRS 任务中收集了 3 维运动学：单脚跳、平板支撑、台阶上举、单腿深蹲和靠墙坐。5 名临床医生对 RRS 表现进行了 3 次评估。使用组内相关系数和 Fleiss κ 分别计算了总 RRS 评分和个别任务的组内和组间可靠性。计算了跑步时测量的峰值关节角度与 RRS 任务中测量的相同角度之间的 Pearson 乘积矩相关系数。比较了高分和低分参与者的峰值关节角度。
评估总 RRS 评分的组内和组间可靠性均良好（组内相关系数分别为 0.75 和 0.80）。评估个别任务的可靠性为中度至近乎完美（κ=0.58-1.00）。跑步时髋关节内收、对侧骨盆下降和膝关节外展与单脚跳、台阶上举和单腿深蹲时测量的相同角度相关（r=0.537-0.939）。跑步时膝关节内旋的峰值与台阶上举时膝关节内旋的峰值相关（r=0.831）。RRS 得分高的跑步者在跑步时膝关节外展幅度较小（P≤0.01）。
RRS 可有效评估新手跑步者的膝关节外展，但可能需要修改评估标准或任务，以有效描述骨盆和横断面上的膝关节运动学。
