Conduction Velocity DLA

Question 1

What is nerve conduction velocity?

Answer 1

• Nerve conduction velocity refers to the speed of propagation of an electrical impulse through a nerve.
• It is assessed by measuring the time it takes for an impulse to travel from one location to another.

• Calculated by dividing the distance traveled by the nerve conduction time
• It helps in the determination of the nature of nerve
injury.

Conduction velocity= D/(T2-T1)

Question 2

How to calculate conduction velocoty?

Answer 2

• To calculate a true motor conduction velocity, two stimulation sites are used (proximal and distal)

• The proximal and distal latency are measured. Considering the difference between these two measurements eliminates the following
– the NMJ transmission time
– the muscle depolarization time.
