The scenario involves damage to two different nerves within the same class, but the initial understanding of the scenario was incorrect.
Median Nerve and Associated Muscles
APD refers to abductor pollicis brevis, which is innervated by the median nerve.
Pronator teres is another muscle controlled by the median nerve.
EMG and ATV Considerations
If an electromyography (EMG) is performed on the pronator teres, and there's an issue, as well as an issue with the abductor pollicis brevis (APB), then both are affected.
