Belt-stabilized handheld dynamometers (HHD) assess hip rate of torque development (RTD) and strength in research and clinical practice. However, the reliability of HHD with push and pull configurations to measure hip muscles RTD and peak torque is unclear.
PURPOSE/HYPOTHESIS: To determine the intra- and inter-reliability of HHD utilizing push and pull configurations to measure hip abduction and extension early (0-100ms) and late (100-200ms) phases RTD and peak torque. We hypothesized HHD with both configurations would be reliable for measuring hip extension and abduction RTD and peak torque.
Cross-sectional study.
Twenty healthy adults (10 females) performed three consecutive maximal isometric contraction trials of hip abduction and extension, utilizing an HHD with push and pull configurations by two raters. Each rater's average early and late phases RTD and peak torque of hip abduction and extension were utilized for analysis.
Intra-rater reliability of hip abduction with push and pull configurations ranged moderate-to-good for early and late RTD phases (push: ICC2,1=0.61-0.88; pull: ICC2,1=0.59-0.75). Peak hip abduction torque showed good reliability in both configurations (ICC2,1≥0.79). Hip extension ranged moderate-to-good reliability for early and late RTD phases in push configuration (ICC2,1=0.72-0.87), with good-to-excellent reliability in pull (ICC2,1=0.77-0.91). Peak hip extension torque showed moderate-to-excellent reliability for push configuration (ICC2,1=0.73-0.92) and excellent reliability for pull (ICC2,1≥0.91). Inter-rater reliability for hip abduction showed moderate in push (ICC3,k≥0.72) and good in pull (ICC3,k≥0.78) configurations for both RTD phases, while hip extension showed good reliability in push (ICC3,k≥0.82) and excellent reliability in pull (ICC3,k≥0.95) configurations. Peak torque showed good reliability for hip abduction (ICC3,k≥0.83) and excellent reliability for extension (ICC3,k≥0.94) in both configurations.
HHD with push and pull configurations is a reliable and cost-effective method for assessing RTD and strength of hip abductors and extensors in healthy adults.

在研究和临床实践中,带稳定装置的手持式测力计(HHD)用于评估髋关节扭矩发展速率(RTD)和力量。然而,具有推和拉配置的HHD测量髋部肌肉RTD和峰值扭矩的可靠性尚不清楚。
目的/假设:确定使用推和拉配置的HHD测量髋关节外展和伸展早期(0 - 100毫秒)和晚期(100 - 200毫秒)阶段RTD和峰值扭矩的内部和外部可靠性。我们假设两种配置的HHD在测量髋关节伸展和外展RTD以及峰值扭矩方面都是可靠的。
横断面研究。
20名健康成年人(10名女性)使用具有推和拉配置的HHD,由两名评估者进行髋关节外展和伸展的三次连续最大等长收缩试验。每个评估者的髋关节外展和伸展的早期和晚期阶段RTD以及峰值扭矩的平均值用于分析。
具有推和拉配置的髋关节外展的评估者内部可靠性在早期和晚期RTD阶段为中等至良好(推:ICC2,1 = 0.61 - 0.88;拉:ICC2,1 = 0.59 - 0.75)。两种配置下的髋关节外展峰值扭矩均显示出良好的可靠性(ICC2,1≥0.79)。推配置下髋关节伸展在早期和晚期RTD阶段的可靠性为中等至良好(ICC2,1 = 0.72 - 0.87),拉配置下为良好至优秀(ICC2,1 = 0.77 - 0.91)。髋关节伸展峰值扭矩在推配置下显示出中等至优秀的可靠性(ICC2,1 = 0.73 - 0.92),拉配置下为优秀(ICC2,1≥0.91)。两种RTD阶段的髋关节外展评估者间可靠性在推配置下为中等(ICC3,k≥0.72),拉配置下为良好(ICC3,k≥0.78),而髋关节伸展在推配置下显示出良好的可靠性(ICC3,k≥0.82),拉配置下为优秀(ICC3,k≥0.95)。两种配置下峰值扭矩在髋关节外展方面显示出良好的可靠性(ICC3,k≥0.83),在伸展方面为优秀(ICC3,k≥0.94)。
具有推和拉配置的HHD是评估健康成年人髋关节外展肌和伸肌RTD和力量的可靠且经济有效的方法。
