Abstract
BACKGROUND Occupational therapists may have an added value in the care of patients with Parkinson's disease whose daily functioning is compromised, as well as for their immediate caregivers. Evidence for this added value is inconclusive due to a lack of rigorous studies. The aim of this trial is to evaluate the (cost) effectiveness of occupational therapy in improving daily functioning of patients with Parkinson's disease. METHODS/DESIGN A multicenter, assessor-blinded, two-armed randomized controlled clinical trial will be conducted, with evaluations at three and six months. One hundred ninety-two home-dwelling patients with Parkinson's disease and with an occupational therapy indication will be assigned to the experimental group or to the control group (2:1). Patients and their caregivers in the experimental group will receive ten weeks of home-based occupational therapy according to recent Dutch guidelines. The intervention will be delivered by occupational therapists who have been specifically trained to treat patients according to these guidelines. Participants in the control group will not receive occupational therapy during the study period. The primary outcome for the patient is self-perceived daily functioning at three months, assessed with the Canadian Occupational Performance Measure. Secondary patient-related outcomes include: objective performance of daily activities, self-perceived satisfaction with performance in daily activities, participation, impact of fatigue, proactive coping skills, health-related quality of life, overall quality of life, health-related costs, and effectiveness at six months. All outcomes at the caregiver level will be secondary and will include self-perceived burden of care, objective burden of care, proactive coping skills, overall quality of life, and care-related costs. Effectiveness will be evaluated using a covariance analysis of the difference in outcome at three months. An economic evaluation from a societal perspective will be conducted, as well as a process evaluation. DISCUSSION This is the first large-scale trial specifically evaluating occupational therapy in Parkinson's disease. It is expected to generate important new information about the possible added value of occupational therapy on daily functioning of patients with Parkinson's disease. TRIAL REGISTRATION Clinicaltrials.gov: NCT01336127.

Abstract
Multidisciplinary care is considered an optimal model to manage Parkinson's disease (PD), but supporting evidence is limited. We performed a randomized, controlled trial (RCT) to establish whether a multidisciplinary/specialist team offers better outcomes, compared to stand-alone care from a general neurologist. Patients with PD were randomly allocated to an intervention group (care from a movement disorders specialist, PD nurses, and social worker) or a control group (care from general neurologists). Both interventions lasted 8 months. Clinicians and researchers were blinded for group allocation. The primary outcome was the change in quality of life (Parkinson's Disease Questionnaire; PDQ-39) from baseline to 8 months. Other outcomes were the UPDRS, depression (Montgomery-Asberg Depression Scale; MADRS), psychosocial functioning (Scales for Outcomes in Parkinson's disease-Psychosocial; SCOPA-PS), and caregiver strain (Caregiver Strain Index; CSI). Group differences were analyzed using analysis of covariance adjusted for baseline values and presence of response fluctuations. A total of 122 patients were randomized and 100 completed the study (intervention, n = 51; control, n = 49). Compared to controls, the intervention group improved significantly on PDQ-39 (difference, 3.4; 95% confidence interval [CI]: 0.5-6.2) and UPDRS motor scores (4.1; 95% CI: 0.8-7.3). UPDRS total score (5.6; 95% CI: 0.9-10.3), MADRS (3.7; 95% CI: 1.4-5.9), and SCOPA-PS (2.1; 95% CI: 0.5-3.7) also improved significantly. This RCT gives credence to a multidisciplinary/specialist team approach. We interpret these positive findings cautiously because of the limitations in study design. Further research is required to assess teams involving additional disciplines and to evaluate cost-effectiveness of integrated approaches. © 2012 Movement Disorder Society.

Abstract
BACKGROUND AND PURPOSE Despite their high prevalence and clinical impact, sleep disorders in Parkinson's disease appear to receive insufficient attention in clinical practice. We compared the importance of sleep disorders relative to other symptoms and daily issues. Furthermore, we determined whether relevance as perceived by patients correlated with the subjective presence of sleep disruption scored with a rating scale. METHODS We studied a cohort of 153 consecutive patients (95 men) who were referred for problems other than sleep to our referral center. Prior to their visit, patients ranked their individual top five clinical priorities (of 23 items), indicating the most problematic domains for which they requested medical attention. Additionally, nocturnal sleep quality and excessive daytime sleepiness (EDS) were assessed with validated questionnaires. RESULTS The top three important domains according to the patient were movement (79.9%), medication (73.2%), and physical condition (63.4%). Sleep was the sixth most frequently reported item, marked by 37.9% of the patients. Amongst the patients who scored sleep as a priority, 47 (81%) had a poor sleep quality (Pittsburgh Sleep Quality Index > 5). Although EDS was present in almost 30% of patients, a minority of them put it on their priority list. CONCLUSION A priority list can be used to prioritize patient-centered quality of life issues. Our results show that sleep is a clinical priority for about one-third of patients. Surprisingly, EDS was usually not prioritized by patients during the consultation, underscoring the need to use ratings scales alongside subjective priorities.

Abstract
AIM To evaluate the feasibility of a randomized controlled trial including process and potential impact of occupational therapy in Parkinson's disease. DESIGN Process and outcome were quantitatively and qualitatively evaluated in an exploratory multicentre, two-armed randomized controlled trial at three months. PARTICIPANTS Forty-three community-dwelling patients with Parkinson's disease and difficulties in daily activities, their primary caregivers and seven occupational therapists. INTERVENTION Ten weeks of home-based occupational therapy according to the Dutch guidelines of occupational therapy in Parkinson's disease versus no occupational therapy in the control group. MAIN MEASURES Process evaluation measured accrual, drop-out, intervention delivery and protocol adherence. Primary outcome measures of patients assessed daily functioning: Canadian Occupational Performance Measure (COPM) and Assessment of Motor and Process Skills. Primary outcome for caregivers was caregiver burden: Zarit Burden Inventory. Participants' perspectives of the intervention were explored using questionnaires and in-depth interviews. RESULTS Inclusion was 23% (43/189), drop-out 7% (3/43) and unblinding of assessors 33% (13/40). Full intervention protocol adherence was 74% (20/27), but only 60% (71/119) of baseline Canadian Occupational Performance Measure priorities were addressed in the intervention. The outcome measures revealed negligible to small effects in favour of the intervention group. Almost all patients and caregivers of the intervention group were satisfied with the results. They perceived: 'more grip on the situation' and used 'practical advices that make life easier'. Therapists were satisfied, but wished for a longer intervention period. CONCLUSIONS The positive perceived impact of occupational therapy warrants a large-scale trial. Adaptations in instructions and training are needed to use the Canadian Occupational Performance Measure as primary outcome measure.

Abstract
INTRODUCTION Patient-centeredness is increasingly recognized as a crucial element of quality of care. A suitable instrument to assess the level of patient-centeredness for Parkinson's disease (PD) care is lacking. Here we describe the development and validation of the Patient-Centered Questionnaire for PD (PCQ-PD), and its initial application in a large patient sample. METHODS Based on the outcomes of eight focus groups we composed a questionnaire that measures patient-centeredness by assessing patients' care experiences. The questionnaire was sent to 1112 Dutch PD patients, and face-, content- and construct-validity and reliability were assessed. The level of patient-centeredness was determined by calculating scores for overall patient-centeredness [0-3], subscale experiences [0-3], item experience, item priority and quality improvement. RESULTS 895 PD patients (net response 82.0%) completed the questionnaire. After the validation procedure, the PCQ-PD addressed 46 care aspects in six different subscales of patient-centeredness. The internal consistency of the instrument, expressed in Cronbach's α per subscale, ranged from 0.62 to 0.84. The overall patient-centeredness score was 1.69 (SD 0.45). 'Emotional support' (1.05, SD 0.90) and 'provision of tailored information' (1.18, SD 0.57) subscales received the lowest experience ratings. 'Access to medical records' obtained the highest item quality improvement score (5.44). CONCLUSIONS This study produced a valid instrument to measure patient-centeredness in PD care. Psychometric properties of the instrument were good. Application of the PCQ-PD revealed the level of patient-centeredness in the care for PD patients in The Netherlands. The main outcome was a compelling call for the provision of tailored information and emotional support.

Abstract
Dysphagia is a potentially harmful feature, also in Parkinson's disease (PD). As published prevalence rates vary widely, we aimed to estimate the prevalence of oropharyngeal dysphagia in PD in a meta-analysis. We conducted a systematic literature search in February 2011 and two independent reviewers selected the papers. We computed the estimates of the pooled prevalence weighted by sample size. Twelve studies were suitable for calculating prevalence rates. Ten studies provided an estimate based on subjective outcomes, which proved statistically heterogeneous (p < 0.001), with a pooled prevalence estimate with random effect analysis of 35% (95% CI 28-41). Four studies provided an estimate based on objective measurements, which were statistically homogeneous (p = 0.23), with a pooled prevalence estimate of 82% (95% CI 77-87). In controls the pooled subjective prevalence was 9% (95% CI 2-17), while the pooled objective prevalence was 23% (95% CI 13-32). The pooled relative risk was 3.2 for both subjective outcomes (95% CI 2.32-4.41) and objective outcomes (95% CI 2.08-4.98). Clinical heterogeneity between studies was chiefly explained by differences in disease severity. Subjective dysphagia occurs in one third of community-dwelling PD patients. Objectively measured dysphagia rates were much higher, with 4 out of 5 patients being affected. This suggests that dysphagia is common in PD, but patients do not always report swallowing difficulties unless asked. This underreporting calls for a proactive clinical approach to dysphagia, particularly in light of the serious clinical consequences.

Abstract
Prior work suggested that patients with Parkinson's disease (PD) have a lower Body Mass Index (BMI) than controls, but evidence is inconclusive. We therefore conducted a meta-analysis on BMI in PD. We searched MEDLINE, EMBASE, Cinahl and Scopus to identify cohort studies on BMI in PD, published before February 2011. Studies that reported mean BMI for PD patients and healthy controls were eligible. Twelve studies were included, with a total of 871 patients and 736 controls (in three studies controls consisted of subjects from other published studies). Our primary aim was to assess differences in BMI between patients and controls; this was analyzed with random effects meta-analysis. Our secondary aim was to evaluate the relation with disease severity (Hoehn and Yahr stage) and disease duration, using random effects meta-regression. PD patients had a significantly lower BMI than controls (overall effect 1.73, 95% CI 1.11-2.35, P<0.001). Pooled data of seven studies showed that patients with Hoehn and Yahr stage 3 had a lower BMI than patients with stage 2 (3.9, 95% CI 0.1-7.7, P<0.05). Disease duration was not associated with BMI. Because a low body weight is associated with negative health effects and a poorer prognosis, monitoring weight and nutritional status should be part of PD management.

Abstract
Background Patients with chronic illness typically receive ambulatory treatment from multiple health professionals. Connectedness between these professionals may influence their clinical decisions and the coordination of patient care. We aimed to describe and analyze connectedness in a regional network of health professionals involved in ambulatory treatment of patients with Parkinson's disease (PD). Methods Observational study with 104 health professionals who had joined a newly established network (ParkinsonNet) were asked to complete a pre-structured form to report on their professional contacts with others in the network. Using social networks methods, network measures were calculated for the total network and for the networks of individual health professionals. We planned to test differences between subgroups of health professionals regarding 12 network measures, using a random permutation method. Results Ninety-six health professionals (92%) provided data on 101 professionals. The reciprocity of reported connections was 0.42 in the network of professional contacts. Measures characterizing the individual networks showed a wide variation; e.g., density varied between 0 and 100% (mean value 28.4%). Health professionals with ≥10 PD patients had higher values on 7 out of 12 network measures compare to those with < 10 PD patients (size, number of connections, two step reach, indegree centrality, outdegree centrality, inreach centrality, betweenness centrality). Primary care professionals had lower values on 11 out of 12 network measures (all but reach efficiency) compared to professionals who were affiliated with a hospital. Conclusions Our measure of professional connectedness proved to be feasible in a regional disease-specific network of health professionals. Network measures describing patterns in the professional contacts showed relevant variation across professionals. A higher caseload and an affiliation with a hospital were associated with stronger connectedness with other health professionals.

Abstract
Patients with Parkinson’s disease (PD) are likely to become physically inactive, because of their motor, mental, and emotional symptoms. However, specific studies on physical activity in PD are scarce, and results are conflicting. Here, we quantified daily physical activities in a large cohort of PD patients and another large cohort of matched controls. Moreover, we investigated the influence of disease-related factors on daily physical activities in PD patients. Daily physical activity data of PD patients (n = 699) were collected in the ParkinsonNet trial and of controls (n = 1,959) in the Longitudinal Aging Study Amsterdam (LASA); data were determined using the LAPAQ, a validated physical activity questionnaire. In addition, variables that may affect daily physical activities in PD were recorded, including motor symptoms, depression, disability in daily life, and comorbidity. Patients were physically less active; a reduction of 29% compared to controls (95% CI, 10–44%). Multivariate regression analyses demonstrated that greater disease severity, gait impairment, and greater disability in daily living were associated with less daily physical activity in PD (R2 = 24%). In this large study, we show that PD patients are about one-third less active compared to controls. While disease severity, gait, and disability in daily living predicted part of the inactivity, a portion of the variance remained unexplained, suggesting that additional determinants may also affect daily physical activities in PD. Because physical inactivity has many adverse consequences, work is needed to develop safe and enjoyable exercise programs for patients with PD.

Abstract
Drooling is an incapacitating feature of Parkinson's disease. Better pathophysiological insights are needed to improve treatment. In this study, we tested the hypothesis that the cause of drooling is multifactorial. We examined 15 patients with Parkinson's disease with distinct diurnal saliva loss ("droolers") and 15 patients with Parkinson's disease without drooling complaints ("nondroolers"). We evaluated all factors that could potentially contribute to drooling: swallowing capacity (maximum volume), functional swallowing (assessed with the dysphagia subscale of the Therapy Outcome Measures for rehabilitation specialists), unintentional mouth opening due to hypomimia (Unified Parkinson's Disease Rating Scale item), posture (quantified from sagittal photographs), and nose-breathing ability. We also quantified the frequency of spontaneous swallowing during 45 minutes of quiet sitting, using polygraphy. Droolers had more advanced Parkinson's disease than nondroolers (Unified Parkinson's Disease Rating Scale motor score 31 vs 22; P=.014). Droolers also scored significantly worse on all recorded variables except for nose breathing. Swallowing frequency tended to be higher, possibly to compensate for less efficient swallowing. Logistic regression with adjustment for age and disease severity showed that hypomimia correlated best with drooling. Linear regression with hypomimia as the dependent variable identified disease severity, dysphagia, and male sex as significant explanatory factors. Drooling in Parkinson's disease results from multiple risk factors, with hypomimia being the most prominent. When monitored, patients appear to compensate by increasing their swallowing frequency, much like the increased cadence that is used to compensate for stepping akinesia. These findings can provide a rationale for behavioral approaches to treat drooling.

Abstract
INTRODUCTION Quality of care is becoming increasingly important in the field of movement disorders. Patient-centeredness is a crucial element of quality of care, but has thus far received limited attention regarding the treatment of movement disorder syndromes. As a first step towards patient-centered care in Parkinson's disease (PD), we explored the unmet needs of PD patients and their informal caregivers. METHODS Eight focus group discussions involving 40 PD patients (mean age 62 years, Hoehn & Yahr stage 1-3) and 20 informal caregivers (mean age 63 years) were organized to explore the experiences in relation to patient-centered care. The key elements of patient-centeredness - as defined by the Picker Institute and the World Health Organization - were used as a framework for discussion and qualitative analysis. RESULTS Patients and informal caregivers desired more emotional support from healthcare professionals, and wanted more active involvement in clinical decision making, but currently lacked sufficient information to do so. Participants also missed the tools to find professionals with PD expertise. Finally, they identified a lack of multidisciplinary collaboration as a major bottleneck in the current healthcare system. CONCLUSIONS We identified various unmet needs among PD patients and informal caregivers. These joint experiences represent a disease-specific model of patient-centeredness for PD, which can assist healthcare professionals in implementing patient-centered care tailored to the preferences of each individual patient. The present findings will be used to construct a patient-centeredness questionnaire for PD that will clarify the quality of care from a patient's perspective.

Abstract
AIM A considerable number of patients who undergo surgery for a lumbosacral radicular syndrome (LRS) continue to experience disability, pain, and loss of work capacity. The goal of the study is to develop a brief screening instrument to identify these patients at risk of residual complaints. METHODS In a prospective study of 277 patients, the predictors for the outcomes disability, pain, and loss of work capacity were investigated. The best predictive model was constructed using a stepwise selection procedure (forward selection), which calculates the discriminative power of the model. Based on the relationship between regression coefficients, a clinical prediction rule was derived that predicted the probability of residual complaints after surgery for LRS. RESULTS At 6 month follow-up 141 patients (51%) had residual complaints. The discriminative power of the instrument was .78 (AUC). The "Nijmegen Outcome of Lumbar Disc surgery Screening-instrument" (NOLDS) was based on the variables "lower education level", "younger age", "pain 3 days postoperatively", "passive pain coping", and "fear of movement/(re)injury". CONCLUSION The results of the study are promising, showing that a brief clinical screening instrument can be used to identify patients at risk of residual complaints at 6 months after surgery for LRS. The early identification of patients at risk having residual complaints may make it possible to start tailored treatment early in the rehabilitation process.
