Timing for emphasis involves changing the normal sequencing of motions to emphasize a particular muscle or a desired activity.

Kabat (1947) wrote that prevention of motion in a stronger synergist will redirect the energy of that

contraction into a weaker muscle. This alteration of timing stimulates the proprioceptive reflexes in the muscles by resistance and stretch. The best results come when the strong muscles score at least "good" in strength (Manual Muscle Test grade 4; Partridge 1954).

There are two ways the therapist can alter the normal timing for therapeutic purposes (O Fig. 2.8, 2.9):

— By preventing all the motions of a pattern except the one that is to be emphasized.

— By resisting an isometric or maintained contraction of the strong motions in a pattern while exercising the weaker muscles. This resistance to the static contraction locks in that

The strong motions of the hip and knee are blocked and the dorsiflexion-eversion of the ankle exercised using repeated stretch reflex. c, d Arm pattern flexion-abduction-external rotation. The stronger shoulder motions are blocked while exercising radial extension of the wrist
