Chris, I’m confused by your question. A static assessment has no movement, therefore a squat cannot be a static assessment. Do you mean a dynamic assessment; overhead squat?
If internal rotation is occurring at the hip and supination at the foot there has to be something going on at the knee. What do you see at the knee? Abduction or Adduction?
A static assessment has no movement but also is a movement where the distal segment is fixed.Your examining the relative movement of the fixed surface(feet) on the rest of the body.
Therefore squat is a STATIC assessment.
To clarify and what really is misunderstood in the industry about static and dynamic assessments. Static assessments are when the patient is standing still or when feet are in contact with the floor. Ie. Posture asessment vs. an inplace squat assessment.
When you are asking someone to perform a forward lunge or throwing a ball, climb stairs, this is a DYNAMIC ASSESSMENT.
It is vital for the personal trainer to understand the anatomy, functional anatomy contracting concentrically/eccentrically and biomechanics and lines of force affecting the entire kinematic chain.
To answer the question, when a client is supinating while demonstrating IR at the hip, the peroneals are eccentric lengthening, lateral gastro is concentrically shortening, at the knee, the quadriceps are concentrically contracting, the ITB is lengthening(eccentric) and glute med and min are concentrically(shortening).
Chris, would a squat truly be deemed a STATIC assessment as opposed to a TRANSITIONAL assessment?
“NASM’s Essentials of Corrective Exercise Training” define transitional assessments as “assessments that involve movement without a change in one’s base of support.” It includes movements such as “squatting, pressing, pushing, pulling and balancing” as transitional assessments. As a consequence, a transitional movement assessment, doesn’t always have to occur standing as one’s base of support can be something other than one’s feet as in the case of a push up.
A STATIC posture in the same textbook is defined as “how individuals physically present themselves in a stance. It is reflected in the alignment of body.”
From the way I have come to understand static and dynamic posture, once an individual performs a squat, although the base of support has not changed, there is, indeed, a change or transition, from the static stance. As there is movement it is no longer static, according to the definition.
I’d be curious to hear your perspective as both you and Dr. Clarke are physical therapists.
