Hyporeflexia is a condition characterized by the absence or diminished reflex in reaction to an applied stimulus. This condition is associated with the lower motor neuron disease defined by a deficit in the nerve that runs through the spinal cord going to the extremities.
Hyporeflexia is the hallmark of LMN lesion .It is also seen in UMN shock
LMN lesions
Isolated loss of a rellex usually suggests radiculopathy.
Symmetrical loss of rellex may be found in peripheral neuropathy.
Reflexes may be absent if the patient is unable to relax.
A reflex seems lost or diminished in defect of technique, relaxation, or observation.
