The effects of verbal cues on EMG activity during a quadriceps setting exercise.

Context: A quadriceps setting (quad set) exercise is commonly utilized following knee injury, but there is great variation in cues that clinicians provide to patients when performing the exercise.

Objectives: To determine if internal, external, or visual cues results in the greatest quadriceps electromyographical (EMG) activity during a quadriceps setting exercise in healthy individuals.

Design: Descriptive laboratory study.
