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. 

Objectives:

• 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. 

Technique:

• 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.
