Hamstring strength testing is crucial in assessing this important muscle group during rehabilitation and injury prevention. The purpose of this study was to evaluate the reliability and validity of measuring strength in a maximally lengthened position using a handheld dynamometer (HHD) compared to isokinetic testing.
Twenty healthy and active participants were recruited, and isometric strength testing was performed both on the Biodex machine and isometric end-range hamstring testing with the HHD on two occasions.
Significant strong correlations (r= 0.87, p < 0.0001) were found between strength testing on the Biodex machine and the HHD for both the right and left sides. Bland-Altman plots demonstrated agreement between the two measurements. Excellent intra-rater reliability (ICC= 0.91-0.93) and moderate to good inter-rater reliability (ICC = 0.71-0.83) for the HHD test was demonstrated.
The HHD provides a reliable and valid alternative to isokinetic testing for assessing hamstring strength in a maximally lengthened position. This assessment can be valuable in monitoring rehabilitation progress and detecting deficits before and after returning to play. The HHD is an accessible and cost-effective option for assessing hamstring strength at long lengths in a clinical setting.
腘绳肌力量测试在康复和损伤预防过程中对评估这一重要肌肉群至关重要。本研究的目的是评估与等速测试相比，使用手持测力计（HHD）在最大伸展位测量力量的可靠性和有效性。
招募了20名健康且活跃的参与者，在Biodex机器上进行等长力量测试，并使用HHD进行两次等长终末范围腘绳肌测试。
在Biodex机器上的力量测试与HHD对左右两侧的测试之间均发现显著的强相关性（r = 0.87，p < 0.0001）。Bland-Altman图显示了两种测量方法之间的一致性。HHD测试显示出极好的组内信度（ICC = 0.91 - 0.93）和中等至良好的组间信度（ICC = 0.71 - 0.83）。
对于在最大伸展位评估腘绳肌力量，HHD为等速测试提供了一种可靠且有效的替代方法。这种评估对于监测康复进展以及在恢复运动前后检测缺陷可能具有重要价值。在临床环境中，HHD是评估长长度腘绳肌力量的一种可及且经济有效的选择。
