Dr. Salsich directs the Musculoskeletal Movement Science Laboratory (MMSL). Projects in the MMSL seek to better understand the contributions of lower extremity alignment and movement patterns to musculoskeletal injury and pain and to test rehabilitation strategies based on this knowledge. Joint motion data is collected using a 3-dimensional motion capture system. Measures of pain and function are obtained through self-report (questionnaires). Muscle performance and joint motion measures are obtained using common physical therapist clinical assessment techniques (manual muscle testing, goniometry).

Title: Medial Collapse Movement Impairments associated with Patellofemoral Pain
Study Design: Observational Study
Objective: to determine the relationship between lower extremity movement impairments and symptom behavior in individuals with patellofemoral pain (PFP). Specific aims test whether or not
1) individuals with PFP demonstrate "medial collapse" (inward movement of the limb) during walking, stair climbing and squatting,
2) the kinematic (joint movement) patterns associated with medial collapse are modifiable within a single session
3) modified kinematic patterns correspond to changes in pain.
Background: Chronic patellofemoral pain (pain around the knee cap) is a common and potentially debilitating musculoskeletal pain condition, yet the mechanism of pai
n development is poorly understood. One recently proposed factor contributing to increased patellofemoral pain (PFP) is a movement impairment consisting of medial collapse of the lower extremity during weightbearing. Characterized by an inward movement of the limb, medial collapse theoretically increases stress on the outside of the patellofemoral joint, which subsequently leads to tissue injury and pain. However, the kinematic faults that define medial collapse (excessive hip adduction, hip medial rotation, knee valgus, and knee lateral rotation) have not been identified in individuals with PFP. Furthermore, it is not clear whether these kinematic faults can be reduced and if so, whether the improved movement pattern leads to a reduction in pain.
