Autonomic disturbances

Tendon Reflex

Impaired or lost if reflex arcs are interrupted.

Motor Deficits

Dissociated Sensory Loss

Dissociated sensory loss involves impairment of some sensory modalities such as pain and temperature with preservation of others such as light touch, vibration and joint space position (proprioception).

Can occur in spinal cord injuries but also in peripheral neuropathies.

Pain

The precise mechanism of its genesis is unclear.

Sensory Disturbances

Sensory fiber involvement can lead to numbness and impaired sensation; abnormal spontaneous sensations such as paresthesia.
