We have described the use of the simple laboratory star-tracing test in assessing the course of the alcohol withdrawal syndrome. Test scores (number of line irregularities) correlated best with clinical estimates of tremulousness (Spearman rho = 0.61) and also correlated with the over-all course of the syndrome as measured by total scores computed from a nurses' clinical rating form. Apart from the basic physiological disturbance, it appears that the other 'main influence on test scores is variation in emotional disturbance. It is concluded that such a performance measure should be a useful objective adjunct in evaluation of treatment of the alcohol withdrawal syndrome.In preparation for carrying out controlled studies of the use of drugs in the alcohol withdrawal syndrome, we wished to develop an objective technique to be used in following the course of the syndrome. W e also required of such a test that it be simple, usable at the bedside and inexpensive, so that others in clinical settings might easily take u p its use.In initial studies we assessed the hundred-minus-seven serial subtraction tesc and found it of no use; performance was most dependent upon the patient's motivation and level of native intelligence, and scores correlated very poorly with the course of improvement. W e then directed our attention to a simple %pointed star-tracing test (Fig. l ) , as described below. Time taken for the patient to complete a tracing as a speed tesc and the number of errors (tracing outside the track) were not found to be useful measures for our purpose. However, the number of line irregularities appearing in the tracing did seem related to the clinical course. In a preliminary group of 9 alcoholics showing withdrawal symp toms initial tracings showed 15 to 35 irregularities per half star and at time of discharge had leveled off at 12 or fewer per half star.A group of 9 female hospital employees of above average intelligence on repeated testing had 6 or fewer irregularities per half star, and 7 medical patients and 13 non-alcoholic psychiatric inpatients scored in a range of less than 12, except for one tremulous patient with an agitated depression who had a high score. As with the alcoholics, the normals and other patients did serial star-tracings both repeated on the same day and on si~ccessive days.

The effect of exercise on arm and hand steadiness was studied in two experiments. Unsteadiness following exercise was 35, 53, and 181% greater than pre-pedaling performance for the treatments in which heart rate (HR) was raised to 100, 130, and 160 bpm respectively. The recovery pattern of steadiness following 6 min. of cycling exercise (mean HR 169 bpm) was measured; immediately following the exercise unsteadiness was 143% greater than during pre-pedaling performance and decreased as more time elapsed between the exercise and the steadiness task. When measured 240 sec. after the exercise, unsteadiness was still 28% greater than in pre-exercise performance. Steadiness is markedly affected by preliminary exercise which raises the activation level, with unsteadiness being greatest at the highest levels of activation.
