CONTEXT
Assessment techniques used to measure functional tasks involving active trunk control are restricted to linear movements that lack the explosive movements and dynamic tasks associated with activities of daily living and sport. Reliable clinical methods used to assess the diagonal and ballistic movements about the trunk are lacking.
OBJECTIVE
To assess the interday reliability of peak muscular power outputs while participants performed diagonal chop and lift tests and maintained a stable trunk.
DESIGN
Controlled laboratory study.
SETTING
University research laboratory.
PATIENTS OR OTHER PARTICIPANTS
Eighteen healthy individuals (10 men and 8 women; age = 32 ± 11 years, height = 168 ± 12 cm, mass = 80 ± 19 kg) from the general population participated.
INTERVENTION(S): Participants performed 2 power tests (chop, lift) using an isotonic dynamometer and 3 endurance tests (Biering-Sørensen, side-plank left, side-plank right) to assess active trunk control. Testing was performed on 3 different days separated by at least 1 week. Reliability was compared between days 1 and 2 and between days 2 and 3. Correlations between the power and endurance tests were evaluated to determine the degree of similarity.
MAIN OUTCOME MEASURE(S): Peak muscular power outputs (watts) derived from a 1-repetition maximum protocol for the chop and lift tests were collected for both the right and left sides.
RESULTS
Intraclass correlation coefficients for peak muscular power were highly reliable for the chop (range, 0.87-0.98), lift (range, 0.83-0.96), and endurance (range, 0.80-0.98) tests between test sessions. The correlations between the power assessments and the Biering-Sørensen test (r range, -0.008 to 0.017) were low. The side-plank tests were moderately correlated with the chop (r range, 0.528-0.590) and the lift (r range, 0.359-0.467) tests.
CONCLUSIONS
The diagonal chop and lift power protocol generated reliable data and appears to be a dynamic test that simulates functional tasks, which require dynamic trunk control.
背景
用于测量涉及主动躯干控制的功能任务的评估技术仅限于线性运动，这些运动缺乏与日常生活活动和运动相关的爆发性运动和动态任务。缺乏用于评估躯干对角线和弹道运动的可靠临床方法。
目的
评估参与者进行对角线砍切和提升测试并保持稳定躯干时的峰值肌肉力量输出的日内可靠性。
设计
对照实验室研究。
设置
大学研究实验室。
患者或其他参与者
来自普通人群的 18 名健康个体（10 名男性和 8 名女性；年龄=32±11 岁，身高=168±12cm，体重=80±19kg）参加了此项研究。
干预措施
参与者使用等速测力计进行了 2 项力量测试（砍切、提升）和 3 项耐力测试（Biering-Sørensen、侧平板左侧、侧平板右侧），以评估主动躯干控制能力。测试在 3 个不同的日子进行，至少相隔 1 周。比较了第 1 天和第 2 天以及第 2 天和第 3 天之间的可靠性。评估了力量测试和耐力测试之间的相关性，以确定相似程度。
主要观察指标
从砍切和提升测试的 1 次重复最大值方案中得出的右侧和左侧峰值肌肉力量输出（瓦特）。
结果
在测试期间，砍切（范围，0.87-0.98）、提升（范围，0.83-0.96）和耐力（范围，0.80-0.98）测试的峰值肌肉力量的组内相关系数非常可靠。力量评估与 Biering-Sørensen 测试之间的相关性较低（r 范围，-0.008 至 0.017）。侧平板测试与砍切（r 范围，0.528-0.590）和提升（r 范围，0.359-0.467）测试中度相关。
结论
对角线砍切和提升力量方案产生了可靠的数据，并且似乎是一种模拟需要动态躯干控制的功能性任务的动态测试。
