Fig. 5. Correlation between hand dexterity task (HDT) and signs of tremor. (A) Changes of tremors in spontaneous behavior (SB) and hand dexterity task (HDT) after MPTP administration. Tremors scores in SB remained high. (B) Positive correlations between average latencies of the left and right hand from Well 1 and the tremor score in SB (R=0.64, p<0.01) and HDT (R=0.33, p<0.01). Trend lines: solid line, tremor in SB; dotted line, tremor in HDT. #p<0.05, *p<0.01 vs. baseline; repeated measures ANOVA. SB, spontaneous behavior; HDT, hand dexterity task; B, baseline.
