[00:00:00]Observe this patient carefully.

[00:00:02]The right hand demonstrates a classic resting tremor occurring when the limb is relaxed and fully supported.

[00:00:07]Notice the rhythmic, involuntary movement while the hand is at rest.

[00:00:11]Now, as the doctor asks the patient to hold a pen and write in the air, the tremor markedly decreases and almost disappears.

[00:00:18]This suppression of tremor during voluntary, goal-directed movement is a characteristic feature of a Parkinsonian resting tremor.

[00:00:24]Unlike action or intention tremors, Parkinsonian tremors are most prominent at rest and improve with movement.

[00:00:30]This clinical finding is a key neurological sign that helps differentiate Parkinsonian tremors from action and intention tremors.
