Sagittal Plane Gait Kinematics in Individuals With Chronic Ankle Instability

Matthew C. Hoch, David R. Mullineaux, Kyoungkyu Jeon, and Patrick O. McKeon

Single joint kinematic alterations have been identified during gait in those with chronic ankle instability (CAI). The purpose of this study was to compare sagittal plane hip, knee, and ankle kinematics during walking in participants with and without CAI. Twelve individuals with CAI and 12 healthy individuals walked on a treadmill at 1.5 m/s. Three-dimensional kinematics were analyzed using mean ensemble curves and independent t tests. Participants with CAI demonstrated less lower extremity flexion during the absorption phase of stance and the limb placement phase of swing, which may have implications for limb placement at initial contact.

The Neuromatrix Theory of Pain and Transactional Theory of Stress and Coping: Improving Understanding of Pain Catastrophizing in Individuals With ACL Reconstruction and Knee Osteoarthritis

Francesca M. Genoese, Matthew S. Harkey, and Shelby E. Baez

The anterior cruciate ligament (ACL) is a commonly injured ligament of the lower extremity, with over 200,000 tears occurring annually. 1 ACL injuries frequently occur in sports that require extensive cutting and pivoting, 2 with a significant number of injuries affecting basketball and soccer
