Abstract
-
Research has shown that Parkinson's disease (PD) is associated with emotional processing deficits. The impact of PD on communication and social interaction is gaining appreciation. Although successful treatments exist for motor signs in PD, few exist for the non-motor symptoms. This study examined the impact of a voice treatment (Lee Silverman Voice Treatment [LSVT; Ramig, Pawlas, & Countryman, 1995]) on facial mobility, social engagement, and emotional experience in PD. Fifty-three poser participants (39 PD; 14 demographically-matched healthy controls [HCs]) were studied. The PD posers were assigned to three groups: 12 received voice therapy (LSVT), 14 received articulation therapy (ARTIC; Spielman et al., 2012), and 13 received no therapy (Untreated). All posers were video-taped, before and after treatment, while producing emotional (happy, sad, and angry) and neutral monologues from the New York Emotion Battery (Borod, Welkowitz, & Obler, 1992). Monologues were divided into 15-second segments and evaluated by 18 naive, yet trained and reliable, raters for facial mobility (amount of non-emotional facial movement) and social engagement (how much the rater wanted to interact with the poser). In addition, immediately following each emotional monologue, posers evaluated three aspects of their emotional experience: (1) intensity of their emotional feelings immediately following the monologue, (2) accuracy with which they carried out the monologue task, and (3) intensity of their emotional feelings throughout the monologue. Results revealed a treatment effect for LSVT, such that PD posers in this group demonstrated improvement in facial mobility, intensity of emotional feelings during the monologue, and immediate feelings after the monologues. Additionally, male posers in the LSVT group reported improved accuracy during the angry monologue following treatment. There were also gender differences; ratings for female posers on facial mobility and immediate emotional feelings were higher than those for male posers. There were no significant results for social engagement. The findings for facial mobility and emotional experience have clinical implications. Enhanced emotional experience may help improve mood disorders that are frequently co-morbid with PD. Further, LSVT might be useful in a broader range of psychiatric disorders. Finally, the findings regarding emotional experience provide exciting avenues for future research.
