Elbow Flexion Improves Scapular Mechanics During Shoulder Flexion
This study found that flexing the elbow during shoulder flexion increases scapular upward rotation and serratus anterior activation, aiding shoulder rehab.
Reliability of EasyAngle® for Measuring Hip ROM in Healthy Children
This study confirms that the EasyAngle® digital goniometer provides good to excellent intrarater and interrater reliability in assessing hip range of motion in children.
Knee Flexion & Hip Extension ROM: Digital Goniometer vs. Motion Tracking
This study shows that both tools showed high reliability for knee and hip ROM, though Kemtai overestimated values compared to EasyAngle®.
Effectiveness of EMMETT technique on Iliotibial band tightness in football players
This study found that the EMMETT manual therapy technique significantly increased iliotibial band flexibility in young male footballers, as measured with EasyAngle®.
Reliability for Knee Range of Motion Measurement
This study demonstrated very high intrarater and interrater reliability of the EasyAngle® digital goniometer for measuring knee joint range of motion.
Validity and Reliability for Hip ROM Measurement in Osteoarthritis
This study found that EasyAngle® shows excellent validity and interrater reliability for measuring active and passive hip range of motion in people with hip osteoarthritis.
Accuracy and Practicality for Cervical Spine Rotation Measurement
This study found that EasyAngle® provides slightly better accuracy than the gold standard CROM device for measuring cervical spine rotation in healthy individuals.
Straight Leg Raise Reliability in Horse Riders
This study demonstrates excellent reliability of the EasyAngle® device for measuring passive straight leg raise.
Scapular Mobility Assessment Reliability
This study found that the EasyAngle® device shows excellent intra-rater reliability for measuring scapular mobility in healthy adults.
Cervical Flexion ROM Validity
This study on the EasyAngle digital goniometer demonstrated strong concurrent validity (ICC 0.97) for measuring cervical flexion range of motion.
Elbow Joint Movements Reliability
This study found that EasyAngle demonstrates good-excellent interrater and acceptable-excellent intrarater reliability for measuring elbow joint movements in healthy adults.
Shoulder ROM and Strength Reliability
This study assessed the reliability and validity of different methods, including EasyAngle, for measuring shoulder internal and external rotation ROM and strength.
Usability and Reliability of EasyAngle
This study evaluated the usability and measurement reproducibility of the EasyAngle goniometer vs traditional metal and plastic goniometers in patients post knee and hip arthroplasty.
Wheelchair Athletes Shoulder Assessment
This study assessed shoulder girdle variables in elite wheelchair athletes and found significant improvements after a 12-week exercise program, measured with EasyAngle®.
Cervical Rotation and Age
This study found that upper cervical rotation measured by the flexion-rotation test decreases with age.
Equine Joint Angle Measurement
This study evaluated a new single-hand digital goniometer against the conventional universal goniometer for measuring joint angles in horses.
Table Slide Shoulder Flexion Test Reliability
This study demonstrated that the table slide shoulder flexion test with EasyAngle® is reliable for early assessment following proximal humeral fracture.
