The patient is positioned in the shortened range/ end position of a movement and is asked to hold. The isometric contraction is resisted followed by voluntary relaxation and passive movement into the lengthened range. The patient is then instructed to move back into the end position; stretch and resistance are applied to facilitate the isotonic contraction. For each repetition, increasing ROM is desired.
Indications Marked weakness, inability to sustain a contraction in the sustained range.
