Key Finding
This study demonstrates excellent reliability of the EasyForce dynamometer for measuring maximal knee and hip strength, comparing its performance to rigid isometric dynamometers with external fixation.
Abstract
This study aimed to assess intra- and inter-visit reliability of a novel EasyForce dynamometer for assessment of maximal strength in knee extension and flexion, and hip abduction and adduction tasks.
The study compared EasyForce measurements with rigid isometric dynamometers with external fixation.
Methods
Young healthy participants (n = 50; 25 males, 25 females; age: 23.4 ± 2.1 years) were measured for maximal joint torque with EasyForce dynamometer and rigid isometric dynamometers with external fixation, in two-sessions (5–10 days apart).
Study Figures
Results
EasyForce demonstrated excellent intra-visit and inter-visit reliability for all measured strength tasks. ICC values ranged from 0.85-0.97 for knee extension/flexion and hip abduction/adduction.
Conclusion
The EasyForce dynamometer provides reliable measurements of maximal knee and hip strength, comparable to rigid isometric dynamometers with external fixation, making it a practical alternative for clinical and research settings.
