ANSWERS WITH VERIFIED SOLUTIONS 100%
CORRECT
A-waves or Axon reflex - correct answer- Seen when using sub-
maximal stimulation during the F-wave recording.
Consistent in latency and amplitude and usually occurring
before the F-wave. Thought to be a result of reinnervation of
the nerve.
Abduct - correct answer- Move away from the median plane
Abductor digiti minimi
(ADM or ADQ) - correct answer- Ulnar innervated
muscle on the medial side of the little finger alongside the
5th metacarpal. The most superficial muscle in the
hypothenar eminence. Commonly used when recording
ulnar motor studies.
Abductor digiti quinti
pedis (ADQp) - correct answer- Medial plantar,
, thus tibial nerve, innervated muscle on the medial side of
the foot below the navicular bone. Commonly used when
recording tibial motor studies.
Abductor pollicis brevis
(APB) - correct answer- Median innervated muscle just medial to the
1st metacarpal
bone. The most superficial muscle of the thenar eminence.
Commonly used when recording median motor studies.
Accessory peroneal nerve - correct answer- A branch of the
superficial peroneal nerve that partly
supplies the extensor digitorum brevis (EDB) in 18-22% of
people. The EDB is normally innervated by the deep
peroneal. The accessory peroneal nerve is seen when the
peroneal amplitude, recording from the EDB, is larger when
stimulating at the fibular head than when stimulating at the
ankle. It can be confirmed by stimulating behind the lateral
malleous, adding that amplitude to the ankle amplitude. The
sum of which should closely equal the amplitude when
stimulating at the fibular head.
