PAS Muscle Imbalance Correction 3

Question 1

Reciprocal inhibition in the context of muscle imbalance refers to which phenomenon?

Accepted Answer

Neural inhibition of an antagonist when its agonist contracts

Answer

Reciprocal inhibition is the neurological process where activation of an agonist causes reflex inhibition of the antagonist, which contributes to weakness in underactive muscles.

Question 2

Which finding during a static postural assessment suggests overactivity of the adductor complex?

Accepted Answer

Foot pronation and knee valgus

Answer

Adductor overactivity contributes to femoral internal rotation and adduction, producing knee valgus and compensatory foot pronation.

Question 3

In upper crossed syndrome, which two muscles are typically overactive?

Accepted Answer

Upper trapezius and pectoralis minor

Answer

Upper crossed syndrome features overactivity of the upper trapezius and pectoralis minor, creating rounded shoulders and forward head posture.

Question 4

A client shows excessive trunk lean to one side during a single-leg squat. Which muscle group is most likely underactive on the stance leg?

Accepted Answer

Hip abductors and gluteus medius

Answer

Trendelenburg-like trunk lean during single-leg stance indicates weakness of the hip abductors and gluteus medius on the weight-bearing side.

Question 5

Which inhibition technique is used in the Inhibit phase of the corrective exercise continuum?

Accepted Answer

Foam rolling and static compression

Answer

Self-myofascial release (foam rolling and static pressure) is used in the Inhibit phase to reduce neural drive to overactive muscles.
