Abstract-We examined the impact of multidisciplinary clinical management of the Parkinson's Disease Research, Education, and Clinical Center program on Parkinson's disease progression. Initial and follow-up scores on the Part III Motor Examination subscale of the Unified Parkinson's Disease Rating Scale (UPDRS) were examined. Overall, 37 (75.5%) of the 49 patients demonstrated stable or improved UPDRS motor scores at 1-to 3-year follow-up; in the 1-year group (n = 28), 22 patients (78.6%) improved, while 6 (21.4%) worsened. In the 2-year group (n = 15), 10 (66.7%) improved, while 5 (33.3%) worsened. In the 3-year group (n = 6), 5 (83.3%) improved, while 1 (16.7%) worsened. Multidisciplinary interventions included neurology (95.9% of patients), physiatry (93.9%), nursing (87.8%), psychology (42.9%), medication changes (59.2% increases, 18.4% decreases), rehabilitation therapies (physical, occupational, speech-language, 67.3%), functional diagnostic testing (18.4%), support group (16.3%), home exercise instruction (85.7%), and disease and wellness education (81.6%). Improved and worsened patients did not significantly differ on the individual program components. Clinical implications and study limitations are discussed.

The efficacy of the multidisciplinary treatment approach to the management of Parkinson's disease (PD) was examined at a regional Veteran's Administration Parkinson's Disease Research, Education and Clinical Center (PADRECC). The records of 43 consecutive individuals with PD were examined. The Unified Parkinson's Disease Rating Scale (UPDRS) was employed to assess disease progression. Changes between initial and one-year follow-up UPDRS motor functioning (Part III) scores were compared to expected disease progression from prior research. In this cohort, thirty patients (69.8%) had improved, 2 were unchanged (4.7%) and 11 patients (25.6%) had worsened at the mean 12.2-month follow-up period. The range of multidisciplinary interventions included neurology (100%), physiatrist (93%), and psychology (41.9%) visits, medication changes (60.5%), rehabilitation therapy (62.8%), functional diagnostic testing (16.3%), support group (9.3%), home exercise programs (86%), and disease and wellness education (83.7%). Statistical analyses of the individual components of the program did not demonstrate significant differences between improvers and non-improvers. Clinical implications and study limitations are discussed.
