To minimize accommodation when applying electrical stimulation to a patient with a neurapraxia, the therapist should:

• A. Decrease the size of the stimulating electrode.
• B. Increase the pulse duration.
• C. Utilize a rapid rate of rise.
• D. Select a biphasic waveform.

Answer: (C)

Minimizing accommodation during electrical stimulation relies on making the nerve reach threshold quickly. A rapid rate of rise creates a sharp, fast-onset stimulus that depolarizes the membrane before accommodation can blunt excitability, leading to better recruitment of motor units. This is especially helpful in neurapraxia, where conduction is temporarily slowed but the axons are still intact, so a quick stimulus more effectively elicits a response. Other approaches—like changing electrode size, increasing pulse duration, or using a biphasic waveform—don’t specifically address the rapid onset needed to overcome accommodation, though they influence other factors such as safety, comfort, or current density.
