EasyForce® Clinical Studies
Evidence-based dynamometry backed by peer-reviewed research demonstrating reliability and validity.
Completed Studies
Published clinical studies demonstrating the reliability and validity of EasyForce® for strength measurements.
Effect of NMES on Muscle Gene Expression
This study found that NMES induces exercise-like molecular effects, with over 4000 differentially expressed genes overlapping 80% with voluntary exercise.
Reliability for Maximal Knee and Hip Strength Assessment
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.
Interrater and Intrarater Reliability for Shoulder, Knee, and Hip Strength
This study found excellent interrater and intrarater reliability of the EasyForce dynamometer for assessing shoulder, knee, and hip muscle strength in healthy young adults.
Reliability for Foot Strength Testing in Athletes
This study found excellent reliability of the Enhanced Paper Grip Test using EasyForce for assessing foot strength in volleyball and soccer athletes.
Balance Assessment in Multiple Sclerosis Patients
This study found excellent intra-visit reliability of the Enhanced Paper Grip Test for quantifying balance deficits in individuals with multiple sclerosis.
Test-Retest Reliability for Knee Strength and Asymmetries
This study demonstrated excellent test-retest reliability of the EasyForce dynamometer for assessing knee strength, inter-limb asymmetries, and hamstring-quadriceps ratios in young healthy adults.
Reliability and Validity Compared to Lafayette Manual Muscle Tester
This pilot study found good to excellent intra-rater reliability of the EasyForce dynamometer and strong concurrent validity compared to the Lafayette Manual Muscle Tester for measuring isometric muscle strength.
Ongoing Studies
