Question: Explain what could be a mechanism by which jendrassik maneuver produces bigger myotatic reflex.
The Jendrassik maneuver is a medical technique that can enhance the knee-jerk reflex. It involves clenching the teeth and interlocking the fingers, then pulling them apart. This maneuver helps to reduce voluntary inhibition of the reflex by creating a distraction. The maneuver works by distracting the patient’s attention and increasing the general level of muscle activity, which in turn enhances the reflex response. By activating the cranial nerves through clenching the jaw as well as upper limbs, this maneuver causes decreases in cortical inhibition and therefore a larger reflex response once the myotactic reflex is elicited immediately following performance of the Jendrassik maneuver. The Jendrassik maneuver can also help prevent conscious inhibition of the reflex.
