Part B (Items 10-14) relates to action tremors of the upper extremities, particularly writing and pouring liquids. Severity is determined by watching the patient carry out the aforementioned activities.

For handwriting, only the dominant hand used for writing is evaluated; the patient writes a standard sentence, his or her name, and the date (item 10). Space is provided on the scoring form for this handwriting sample, which would then be part of the patient record. Drawing is also evaluated by having the patient carry out this activity on the scoring form. Space is available for assessing each hand. To allow consistent evaluation over time, the patient should not rest the drawing hand and forearm on the table or desk. This, of course, makes the task more difficult and the test more sensitive.

• Tasks A and B are the drawing of an Archimedes' spiral. The quantitation of these tasks is defined in the table below (Part B) (items 11-13) and is based on the crossing of the lines in the figure. There is less space available between the lines in part B, making the task more difficult.
• Task C for drawing requires the patient to draw a straight line between narrow confines, three times; each time the confines become narrower, thereby increasing the difficulty. These three drawing tasks, by having different levels of difficulty, give a more precise reflection of tremor severity.
• Pouring water from one cup to another is also quantified. Cup size and the amount of water used in the tests are specified to ensure consistency between examination events and among clinicians. The amount of water spills is the basis for the severity grading. The definitions for scoring both pouring and drawing are provided in the table (items 10-14).
