Objective: To investigate how the social interaction relates to activities of daily living (ADL) and motor function in patients with Parkinson’s disease (PD).

Background: In old age, declining social interaction, such as participating in few activities with others or having a small social network and so on, has been related with physical deterioration. But in PD, this relation is not investigated.

Method: Subjects were 114 patients with PD (male: female=53:61, mean age 72.6 years old, MMSE 27.1±2.8, UPDRS total 21.5±11.6, Yahr≦4) , who had been examined social interaction, activity of daily living (ADL) and motor function using Index of social interaction (ISI) and Unified Parkinson’s Disease Rating Scale (UPDRS). We assessed the correlation of ISI and UPDRS; part2 and 3. Based on the results of previous study of the elderly and our study of PD in last year, gender difference was revealed in social interaction. So, we analyzed the results with separating the sexes.

Results: In gender comparison (male vs female), there were no significant differences in age, disease duration, MMSE, UPDRS total and part2 scores. ISI (p=.012) and ‘talking’ that one of the lower items in UPDRS part2 (p=.039) were worse in male than in female. UPDRS part3 was worse in female than in male (p=.017). About correlation between ISI and UPDRS; part2 and 3, in male, the section score and lower items had correlate with ISI were UPDRS part2 total score, part3 total score, the following lower items ‘speech(in part2)’ ‘handwriting’ ‘dressing’ ‘hygiene’ ‘freezing when walking’ and ‘speech(in part3)’ (r=-.273~-.509, p=.000~0.48). On the other hand in female, that was only the lower item of ‘hygiene’ (r=-.260, p=.041).

Conclusion: The social interaction correlated well with ADL and motor function in male patients with PD. However, this correlation was weaker in female than in male. The social interaction of female patients is more robust than male, regardless of their ADL and motor function level.
