This advanced course has been designed to enhance the understanding of the contributing underlying impingement (compression) and instability (malalignment) considerations associated with typical impingement or instability syndromes. Participants will be able to relate and integrate calcaneal (ground) impingement with femoral instability, pelvis impingement and scapula instability or thoracic malalignment. Impingement and instability integration, for ground control and overhead activity, will be introduced using PRI reference centers and frontal plane oscillation. Scapula function will be presented to reduce femoral/tibia instability, and associated thoracic, calcaneal/talus, and pelvis impingement.
