PNF Technique: Agonistic Reversals

The agonistic reversal technique, (or combination of isotonics) is used to facilitate functional movement throughout a pattern or task.
Both concentric and eccentric contractions of the agonist musculature are used.

The focus of the technique is to promote functional stability in a smooth, controlled manner (controlled mobility).
Other goals include increasing muscle strength and endurance, improving coordination, and training eccentric control.

To implement the technique, a concentric contraction of the agonist muscle group(s) is resisted, through a specific direction, and range of the chosen pattern or task.
At the desired endpoint of the movement, the patient holds isometrically against resistance.
The clinician then resists the patient’s slow, controlled return toward the beginning of the movement pattern, promoting an eccentric contraction.
The patient holds again at the completion of the eccentric phase to further encourage stability in this range.
In summary, the technique begins with resistance to a concentric contraction, followed by a stabilizing hold, resistance to an eccentric contraction, and another stabilizing hold.
The agonist muscle groups are targeted throughout this sequence.
