Research has shown that muscles can be stretched more effectively during a period of inhibition called a ‘recovery period’, produced immediately after muscle contraction.

Post-Isometric Relaxation, PIR, technique involves asking the patient to contract a muscle (eg. in the arm, leg, jaw etc), just prior to the practitioner applying a stretch to that muscle.

This is normally repeated three times, each time taking the stretch a little bit further, but always safely and within the tolerance levels of the patient.
