Primary Outcome Measures
NameTimeMethod
Tremor AmplitudeAfter 10 minutes of limb cooling treatment.

Average tremor amplitude during the Outstretched, Abducted, Nose, and Mug conditions of the Tremor Rating Scale test.

Secondary Outcome Measures
NameTimeMethod
Tremor Rating ScaleAfter 10 minutes of limb cooling treatment.

Arm tremor severity was rated on a scale from 0=None to 4=Severe during each of four conditions: arm outstretched, hand close to mouth and arm abducted, performing a finger to nose maneuver, and holding a mug. The Tremor Rating Scale score was the mean of the scores for the four conditions, and ranged from a score of 0=None to 4=Severe.
