OBJECTIVE: To examine whether Parkinson's disease affects men and women differently, relative to age-matched controls, in manual tracking. DESIGN: Cross-sectional exploratory study. SETTING: Ambulatory activity center. PARTICIPANTS: Ten men and 10 women with Parkinson's disease; 10 men and 10 women age-matched controls. INTERVENTIONS: Patients tracked a sinewave target on a computer monitor in stimulus-response compatible (finger extension/flexion in vertical) or incompatible (horizontal) conditions. MAIN OUTCOME MEASURE: Accuracy Index (AI) score on finger movement tracking tests. RESULTS: With data collapsed across sexes, AI scores were significantly higher for control subjects compared with subjects with Parkinson's disease in compatible (P<.001) and incompatible (P<.001) positions. With data partitioned out across sexes, control men tracked significantly higher than men with Parkinson's disease in compatible (P=.004) and incompatible (P<.001) positions, but control women did not track significantly different from women with Parkinson's disease in either position. Control men tracked significantly higher than control women in compatible (P=.003) and incompatible (P=.001) positions, but men with Parkinson's disease did not track significantly different from women with Parkinson's disease in either position. CONCLUSION: Parkinson's disease affects men and women disproportionately in manual tracking. Comparisons between subjects with Parkinson's disease and controls in spatial skill should include sex as a factor. More research is needed to confirm these findings.
