Hyporeflexia of lower limbs

What it means

Reduced intensity of muscle tendon reflexes in the lower limbs. Reflexes are elicited by stretching the tendon of a muscle, e.g., by tapping.

Reflexes are sensorimotor arcs that require some type of sensory (afferent) signal, and some motor response. While the simplest of reflexes involve direct synapse between the sensory fiber and the motor neuron (monosynaptic), many reflexes have several neurons interposed (polysynaptic reflexes). Hyporeflexia can result from a defect anywhere in this chain.
