Nerve conduction studies performed on healthy adults revealed that age is negatively associated with the sensory amplitude measures of the Median, Ulnar, and Sural nerves. Negative associations were also found between age and the conduction velocities and latencies in the Median sensory, Median motor, and Ulnar sensory nerves.
Electromyographic studies and nerve conduction studies show normal motor conduction velocity and latency with decreased amplitude of compound muscle action potentials. Pathologically, it is a noninflammatory axonopathy without demyelination. [3] Antibodies attack the coating of the motor neurons without causing inflammation or loss of myelin ...
Ulnar neuropathy is a disorder involving the ulnar nerve. Ulnar neuropathy may be caused by entrapment of the ulnar nerve with resultant numbness and tingling. [3] It may also cause weakness or paralysis of the muscles supplied by the nerve. Ulnar neuropathy may affect the elbow as cubital tunnel syndrome.
Sensory neuronopathy is diagnosed clinically, based on signs and symptoms, along with nerve conduction studies. [1] Ataxia in the upper and lower extremities at onset or at full development, asymmetric distribution of sensory loss, sensory loss not being restricted to the lower limbs (as in length dependent axonal polyneuropathy) are specific ...
Treatment Occupational therapy, weight decrease (management) [ 1 ] Polyneuropathy (from Greek poly- 'many' neuro- 'nerve' and -pathy 'sickness') is damage or disease affecting peripheral nerves ( peripheral neuropathy ) in roughly the same areas on both sides of the body, featuring weakness , numbness , and burning pain.

Nerve conduction velocity is an important aspect of nerve conduction studies. It is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, including age, sex, and various medical conditions.
The oculomotor nerve controls all the muscles that move the eye except for the lateral rectus and superior oblique muscles. It also serves to constrict the pupil and open the eyelid. The onset of a diabetic third nerve palsy is usually abrupt, beginning with frontal or pain around the eye and then double vision. All the oculomotor muscles ...
A variety of nerve types can be subjected to neurapraxia and therefore symptoms of the injury range in degree and intensity. Common symptoms of neurapraxia are disturbances in sensation, weakness of muscle, vasomotor and sudomotor paralysis in the region of the affected nerve or nerves, and abnormal sensitivity of the nerve at the point of injury.
