aMNCV, motor nerve conduction velocity; bS: Superficial sensitivity (light, touch temperature…); D: deep sensitivity (vibration, space…); cO: optic atrophy; N: nystagmus.
This feasibility study explored the effects of ice as a single stimulus on disturbed wrist position sense, sensation of light touch and temperature discrimination of the affected hand.
Loss of joint-position sense, discriminative light touch, vibration, pain, temperature, and scratch sensations may be lost or impaired.
Sensory tests include pinprick sensation, light touch, vibration, and temperature perception.
Sensation was slightly diminished to vibration and proprioception in toes bilaterally but preserved to light touch, pinprick, and temperature.
The patient had paresthesias and dysethesias in both hands and feet; sensory responses to light touch, pinprick and temperature were intact.
Many of our patients had clinically detectable cortical sensory deficits (e.g. astereognosis or dysgraphesthesia), despite preservation of basic sensory modalities (light touch, pin prick, temperature and vibration).
Published: February 12 , 2015Skin is the largest sensory organ of the body and is densely equipped with highly specialized sensory nerve endings capable of sensing a wide range of sensory stimuli such as light touch, mechanical pressure, temperature, itch, and pain.
The sensory functions of the nerve are examined by stimulating the face gently with the finger or cotton for light touch, cold steel for temperature, and a pin for scratch or pain sensation.
