Introduction to the Overhead Squat Assessment

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).
