What is resting tremor commonly associated with?

• A. Excess muscle tone
• B. Involuntary shaking of relaxed muscles
• C. Continual vocal sounds
• D. Difficulty with breath control

Answer: (B)

Resting tremor is characterized by the involuntary shaking of relaxed muscles, typically observed when a person is at rest and not actively moving. This type of tremor is often associated with conditions like Parkinson's disease, where it is commonly seen in the hands, fingers, or limbs. During rest, the muscles are not engaged, and the tremor occurs due to abnormal neuronal activity that leads to oscillations in muscle tone.

In contrast, excess muscle tone relates more to issues of rigidity rather than tremor, continual vocal sounds are related to vocalization disorders, and difficulty with breath control pertains to respiratory issues. Therefore, the correct answer specifically identifies the hallmark feature of resting tremor, emphasizing its occurrence in relaxed muscle states.
