ROAM ™ OA REDUCED KNEE ADDUCTION ANGLES IN MAJORITY OF PATIENTS. Lower knee adduction angle led to a more balanced mediolateral load distribution.
The blue line shows joint movement and joint angle changes during gait when ROAM is worn versus the gray line representing when no brace is applied. As indicated in the blue line, ROAM reduced knee adduction angles in majority of patients. Lower knee adduction angle led to a more balanced mediolateral distribution.

ROAM OA IMPROVED LOAD ACCEPTANCE AFTER HEEL STRIKE WHICH IMPROVED THE FLEXION-EXTENSION PATTERN FROM EARLY TO MIDSTANCE PHASES. Healthier quadriceps use was suggested based on the increased flexion movements during stance phase of gait. The blue lines in the knee flexion graphs show that ROAM improved load acceptance after heel strike which improved the flexion-extension pattern from early to midstance.
