The Level 621course buildson the work begun in the C-500 level courses. This course ispredominantly lab-based and isfocused on the evaluation and management of human movementin the lower extremity (hip/knee/ankle-foot). Thiscourse builds a detailed evaluation plan for the lower extremity. In depth joint biomechanics provide the basis for analyzing movement and determining its relationship to the presenting patient's health condition and impairments. Specifically, the mobilityand stabilityof the lower extremityneuromusculoskeletal systemisstudied, along with the central and spinal neurophysiological factors that determine normal and abnormal movement patterns. Assessment techniques for each of these components will be demonstrated, practiced, and applied to various case scenarios. Secondly, a significant portion of this coursewill be spent demonstrating, practicing, and applying specific, directional, and focused manual therapy techniques to the lower extremity. Focusingtechniques will be taught in order to develop participants' skills in localizingand minimizing the forces used, and effort needed, during mobilization and manipulation.
