Jendrassik's manoeuvre
Web13 dic 2005 · Short-length muscle contraction (hold-short conditioning) causes limb position sense errors after the muscle returns to its intermediate length; this is due to intrafusal muscle thixotropy, which raises the muscle spindle sensitivity. In humans, contraction of muscles in the upper body (referred to as the Jendrassik manoeuvre) reinforces tendon … WebSeveral mechanisms were investigated by which the Jendrassik manoeuvre might potentiate tendon jerk and H-reflexes, recorded here as surface EMG from the triceps surae muscle group. If fusimotor activation is involved, then, after muscle conditioning designed to leave spindles in a slack state, inte …

The Jendrassik maneuver is a medical maneuver wherein the patient clenches the teeth, flexes both sets of fingers into a hook-like form, and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited response is compared with the reflex result of the same action when the maneuver is not in use.
