Dr. Brent Brookbush teaches the sign "Posterior Pelvic Tilt" during a lecture on the Overhead Squat Assessment OHSA with Modification (Heel Rise)

Definition:

Overhead Squat Assessment (OHSA) - A dynamic/transitional posture Assessment that combines end-range shoulder flexion with a squat (sit-to-stand transfer).

Why the OHSA (Relevance)?  This assessment is designed to highlight deviations from ideal motion with the intent of informing intervention selection. Dynamic/transitional postural assessments are particularly well suited for highlighting altered movement patterns that may incorporate multiple body segments, joints, muscles, fascia and/or neural structures. That is, this category differs from most assessments which attempt to identify a single structure or joint motion that may be contributing to the patient/client's complaints.  For example, although a manual muscle test for the gluteus medius may indicate gluteus medius weakness.; the OHSA may imply that this weakness is a contributing factor of a lower extremity compensation pattern that includes additional structures crossing the hip, knee and ankle - as is often the case when an individual exhibits the sign Knees Bow In (discussed in greater detail below).

  • What the OHSA is Not:  The overhead squat assessment is not a diagnostic test. The overhead squat is not designed to be a valid measure of joint or
