What type of tremor is described as "pill rolling" in Parkinson's patients?

The term "pill rolling" specifically refers to a characteristic type of movement associated with resting tremors observed in individuals with Parkinson's disease. This tremor occurs when the hands are at rest, usually involving a repetitive motion that resembles the act of rolling a pill between the thumb and fingers.

Resting tremors are distinctly different from other types of tremors because they are most prominent when the muscles are relaxed and tend to diminish during purposeful movement. This feature is particularly indicative of Parkinson's disease, contributing to the hallmark symptoms that characterize the condition. As a result, identifying it as a resting tremor is essential for understanding the motor manifestations associated with Parkinson's disease.
