Patellar reflex: II. Associated activation

Human Physiology Aims and scope Submit manuscript

Abstract

Skeletal muscle activation accompanying voluntary (or involuntary) constriction of a local group of muscles and the use of the Jendrassik maneuver has been studied. Voluntary contraction of hand muscles, e.g., by squeezing a hand dynamometer, is the most convenient method for inducing the associated activation of skeletal muscles, thereby reinforcing the patellar reflex. Here, this method is also conventionally called the Jendrassik maneuver. In addition, the effects of sound and light on the patellar reflex have been studied.
