ABSTRACT

INTRODUCTION: Management of Parkinson's disease (PD) and atypical parkinsonism in nursing homes depends on a timely and accurate diagnosis. However, little is known about the diagnostic accuracy of these parkinsonian syndromes in nursing homes. We examined this issue in a large group of Dutch nursing home residents. METHODS: Twelve large nursing home organizations in the Netherlands accounting for 100 nursing homes with a total population of 5480 residents participated. Residents with PD or atypical parkinsonism were identified according to their nursing home medical chart diagnosis. Additionally, local pharmacists provided a list of all residents using antiparkinson medication. We compared the admission diagnosis to a clinical diagnosis made in the study, based upon interview and detailed neurological examination by movement disorders experts. Diagnoses were based on accepted clinical criteria for PD and atypical parkinsonism. RESULTS: In the total population of 5480 residents, 258 had previously been diagnosed with a form of parkinsonism according to their medical record. In 53 of these residents (20.5%) we changed or rejected the diagnosis. Specifically, we found no parkinsonism in 22 of these 53 residents (8.5% of all patients with suspected parkinsonism). In the remaining 31 residents (12%), we established a new diagnosis within the parkinsonian spectrum. CONCLUSIONS: In a large population of Dutch nursing home residents, 20% of diagnoses within the parkinsonian spectrum were inaccurate. Almost 9% of residents had inadvertently received a diagnosis of parkinsonism. Better recognition of parkinsonism in nursing homes is important, because of the consequences for management and prognosis.

ABSTRACT

BACKGROUND: The 'applause sign' a tendency to continue applauding in response to instructions to clap three times was described in 1995 and was considered specific to degenerative disease, especially to atypical parkinsonian disorders. In early phase Parkinson's disease (PD) the sign has been reported positive as well. In late stage PD it is unknown whether and to what extent the sign may be elicited and it remains unknown if and to what degree the sign correlates to cognitive impairment and PD related dementia. METHODS: Nursing home residents with PD (MMSE >17) were included. All patients underwent the clapping test and were tested for cognitive disturbance by making use of accepted clinimetrics (MMSE and Scopa-cog). T-testing was performed with the hypothesis that patients expressing the applause sign would score lower on the MMSE or Scopa-cog. RESULTS: Seventy three nursing home residents (mainly Hoehn and Yahr 4/5) with a mean disease duration of 10 years and a mean age of 78.7 years were included. The applause sign was found positive in 15 of 73 residents (20.5%). Residents expressing the applause sign had significantly lower mean scores on the MMSE (25.1 vs 22.9 points, p < 0.006) and Scopa-cog (14.8 vs 12.0 points, p < 0.039). CONCLUSIONS: The applause sign is present in late stage PD and correlates with a higher degree of cognitive impairment as established with accepted clinimetric tests. A higher degree of frontal lobe involvement explains the presence of the applause sign.

ABSTRACT

BACKGROUND: Mu rhythm desynchronisation via EEG-neurofeedback (NFB) has been previously been shown to induce durable motor-cortical disinhibition for at least 20 min. It was hypothesised that the presentation of a novel procedural learning task immediately after this NFB protocol would boost motor performance. METHOD: The protocol consisted of firstly activating the right primary motor cortex with a single session of Mu (8-12 Hz) suppression via NFB for a total of 30 min. Shortly after, and with their non-dominant (left) hand, subjects (n=10) performed the serial reaction time task (SRTT), which is used to assess reaction time improvement over multiple trials. During another occasion (1 week before/after), the same subjects were tested on a different sequence without prior NFB, as part of a counterbalanced control condition. RESULTS: Compared to a "cross-over" condition without NFB, subjects who received NFB immediately prior to SRTT performance exhibited a significantly faster rate of learning, reflected in a greater reduction of reaction times across blocks (p=0.02). This occurred in the absence of explicit awareness of a repeating sequence. Moreover, no significant differences were observed between conditions in error rate or reaction time variability. CONCLUSION: Our results suggest that a single NFB session may be directly used to facilitate the early acquisition of a procedural motor task, and are the first to demonstrate that neurofeedback effects could be exploited immediately after individual training sessions so as to boost behavioural performance and learning.

ABSTRACT

BACKGROUND: Although physical activity is beneficial for Parkinson's disease (PD) patients, many do not meet the recommended levels. The range of physical activity among sedentary PD patients is unknown, as are factors that determine this variability. Hence, we aimed to (1) assess daily physical activity in self-identified sedentary PD patients; (2) compare this with criteria of a daily physical activity guideline; and (3) identify determinants of daily physical activity. METHODS: Daily physical activity of 586 self-identified sedentary PD patients was measured with a tri-axial accelerometer for seven consecutive days. Physical fitness and demographic, disease-specific, and psychological characteristics were assessed. Daily physical activity was compared with the 30-min activity guideline. A linear mixed-effects model was estimated to identify determinants of daily physical activity. RESULTS: Accelerometer data of 467 patients who fulfilled all criteria revealed that >98% of their day was spent on sedentary to light-intensity activities. Eighty-two percent of the participants were 'physically inactive' (0 days/week of 30-min activity); 17% were 'semi-active' (1-4 days/week of 30-min activity). Age, gender, physical fitness, and scores on the Unified Parkinson's Disease Rating Scale explained 69% of the variability in daily physical activity. CONCLUSIONS: Performance-based measurements confirmed that most self-identified sedentary PD patients are 'physically inactive'. However, the variance in daily physical activity across subjects was considerable. Higher age, being female, and lower physical capacity were the most important determinants of reduced daily physical activity. Future therapeutic interventions should aim to improve daily physical activity in these high-risk patients, focusing specifically on modifiable risk factors.

ABSTRACT

Bone loss is more common in Parkinson's disease (PD) than in the general population. Several factors may be involved in the development of bone loss, including malnutrition, immobilization, low body mass index, decreased muscle strength, vitamin D deficiency and medication use. This study investigates the prevalence of osteoporosis and possible risk factors associated with bone loss in early stage PD. In 186 PD patients (Hoehn and Yahr stage 1-2.5, mean age 64.1 years, 71 % men) bone mineral density (BMD) measurements were performed with DEXA. T- and Z-scores were calculated. Univariate linear regression analysis was performed to identify variables that contributed to BMD. 25-OH-vitamin D status of PD patients was compared with 802 controls (mean age 63.3 years, 50 % men) using linear regression analysis. Osteoporosis (11.8 %) and osteopenia (41.4 %) were common in PD patients. Mean Z-score for the hip was 0.24 (SD 0.93), and for the lumbar spine 0.72 (SD 1.91). Female gender, low weight, and low 25-OH-vitamin D were significantly correlated with BMD of the hip and lumbar spine. PD patients had lower 25(OH)D serum levels than controls (B = -10, p = 0.000). More than half of the patients with early stage PD had an abnormal BMD. Female gender, low weight, and low vitamin D concentration were associated with bone loss. Furthermore, vitamin D concentrations were reduced in PD patients. These results underscore the importance of proactive screening for bone loss and vitamin D deficiency, even in early stages of PD.

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

Because of the complex nature of Parkinson's disease, a wide variety of health professionals are involved in care. Stepwise, we have addressed the challenges in the provision of multidisciplinary care for this patient group. As a starting point, we have gained detailed insight into the current delivery of allied healthcare, as well as the barriers and facilitators for optimal care. To overcome the identified barriers, a tertiary referral centre was founded; evidence-based guidelines were developed and cost-effectively implemented within regional community networks of specifically trained allied health professionals (the ParkinsonNet concept). We increasingly use ICT to bind these professional networks together and also to empower and engage patients in making decisions about their health. This comprehensive approach is likely to be feasible for other countries as well, so we currently collaborate in a European collaboration to improve community care for persons with Parkinson's disease.

ABSTRACT

Drooling as symptom of Parkinson's disease (PD) has thus far been poorly defined. This uncertainty is reflected by high variations in published prevalence rates. The aim of this study was to investigate the prevalence of saliva loss versus accumulation of saliva as a possible preliminary stage, and diurnal drooling versus nocturnal drooling. In addition, we evaluated the association between drooling severity and the severity of facial and oral motor disorders. We collected age, disease duration, UPDRS III and Hoehn & Yahr stage from 104 consecutive outpatients with PD. Diurnal and nocturnal drooling was evaluated with a validated questionnaire (ROMP-saliva). A speech pathologist, blinded for drooling severity, rated facial expression, involuntary mouth opening and difficulty with nose breathing and also interviewed patients about sleeping position and nose-breathing during the night. Thirty patients (29%) had no complaints with saliva control ('non-droolers'), 45 patients (43%) experienced accumulation of saliva or only nocturnal drooling ('pre-droolers'), and 29 (28%) had diurnal drooling (24 of which also drooled during the night; 'droolers'). The droolers had longer disease duration (10 vs. 7 years, p = 0.01) and drooling was independently associated with involuntary mouth opening (OR = 2.0; 95% CI 1.02-3.99) and swallowing complaints (OR = 1.2; 95% CI 1.03-1.31). Diurnal drooling-defined as dribbling of saliva while awake-is present in about 28% of PD patients. This is less than usually reported. Diurnal drooling typically appeared later in the disease course. The association with oral motor behavior should encourage the development of behavioral treatment approaches.

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

Near-infrared spectroscopy (NIRS) is a non-invasive optical imaging technique, which is increasingly used to measure hemodynamic responses in the motor cortex. The location at which the NIRS optodes are placed on the skull is a major factor in measuring the hemodynamic responses optimally. In this study, the validity of using transcranial magnetic stimulation (TMS) in combination with a 3D motion analysis system to relocate the TMS derived position was tested. In addition, the main goal was to quantify the advantage of using TMS to locate the optimal position in relation to the most commonly used EEG C3 position. Markers were placed on the TMS coil and on the head of the subject. In eleven subjects, a TMS measurement was performed to determine the individual motor-evoked potential center-of-gravity (MEP-CoG). This procedure was repeated in nine subjects to test the validity. Subsequently, hemodynamic responses were measured at the MEP-CoG position and at the C3 position during a thumb abduction and adduction task. On average, the MEP-CoG location was located 19.2mm away from the C3 position. The reproducibility study on the MEP-CoG relocation procedure revealed no systematic relocations. No differences in early and delayed hemodynamic responses were found between the C3 and MEP-CoG position. These results indicate that using TMS for NIRS optodes positioning on the motor cortex does not result in higher hemodynamic response amplitudes. This could be explained if NIRS and TMS assess slightly different functions.

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.

ABSTRACT

OBJECTIVE: To evaluate the implementation of an intensive group exercise program in patients with rheumatoid arthritis (RA). METHODS: In 4 regions in The Netherlands, the Rheumatoid Arthritis Patients In Training exercise program was implemented on a limited scale. Evaluation using the RE-AIM model included: Reach, the proportion of the target population participating; Efficacy, effects on muscle strength, aerobic capacity, functional ability, and psychological functioning; Adoption, program adoption by stakeholders; Implementation, intervention quality (quality audits); and Maintenance, stakeholders' willingness to continue the program in the future. RESULTS: Twenty-five physical therapists from 14 practices were trained to provide the program. In total, 150 RA patients were recruited (by estimation, 2% of the target population). Of the 81 patients who had finished the 12-month intervention and were available for followup directly after the intervention, 62 patients provided clinical data. Muscle strength improved significantly, whereas aerobic capacity, functional ability, psychological functioning, and disease activity did not change. All 9 informed local patient organizations facilitated patient recruitment, and 35 of 51 rheumatologists involved referred one or more patients. All 10 approached health insurance companies funded the program for 12 months. The quality audits showed sufficient quality in 9 of 12 practices. All of the providers of the program were willing to provide the program in the future, whereas future reimbursement by health insurance companies remained unclear. CONCLUSION: The implementation of an intensive exercise program for RA patients on a limited scale can be considered successful regarding its reach, adoption, and implementation. The limited effectiveness and the limited data regarding maintenance warrant additional research.

ABSTRACT

AIM: The aim of this paper was to develop and evaluate a patient-specific index for physiotherapy in Parkinson's disease (PSI-PD). METHODS: In the PSI-PD, patients 1) select problematic activities out of a predefined list, with one self-report item; 2) rank selected items in order of importance; and 3) rate severity for each ranked item. To examine test-retest reliability, a cohort of patients was asked to complete the PSI-PD twice. Afterwards, validity was evaluated using a telephone interview. RESULTS: The PSI-PD was completed twice by 81 patients. Test-retest agreement for the selection of activity limitations was 73% to 94%. Items ranked by patients were categorized into domains, of which gait, transfers and dexterity were rated most frequently (41%-70%). Test-retest agreement for ranked domains ranged from 74% to 82%. Interviews confirmed that the PSI-PD reliably identified problem areas. CONCLUSIONS: The PSI-PD is a relevant, reliable and valid instrument to identify limitations in everyday activities that are important for both PD patients and physiotherapists.

ABSTRACT

BACKGROUND AND AIMS: Muscle weakness is a potentially important, yet poorly studied, risk factor for falls. Detailed studies of patients with specific myopathies may shed new light on the relation between muscle weakness and falls. Here falls in patients with facioscapulohumeral disease (FSHD) who suffered from lower limb muscle weakness were examined. This study provides insights into the prevalence, relevance and pathophysiology of falls in FSHD. METHODS: A validated questionnaire was used as well as a prospective 3 month follow-up to examine the prevalence, circumstances and consequences of falls in 73 patients with FSHD and 49 matched healthy controls. In a subgroup of 28 subjects, muscle strength was also examined and balance was assessed electrophysiologically using body worn gyroscopes. RESULTS: In the questionnaire, 30% of the patients reported falling at least once a month whereas none of the controls did. Injuries occurred in almost 70% of the patients. The prospective study showed that patients fell mostly at home, mainly due to intrinsic (patient related) causes, and usually in a forward direction. Fallers were unstable while climbing stairs, rising from a chair and standing with eyes closed whereas non-fallers had normal balance control. Frequent fallers had greater muscle weakness than infrequent fallers. CONCLUSION: These findings demonstrate the high prevalence and clinical relevance of falls in FSHD. The relation between muscle weakness and instability among fallers is also highlighted. Because patients fell mainly at home, fall prevention strategies should focus on home adaptations. As mainly intrinsic causes underlie falls, the impact of adopting balance strategies or balance training should be explored in this patient group.

ABSTRACT

AIM: The aim of this study was to develop quality indicators for physiotherapy in Parkinson's disease (PD) according to international criteria. METHODS: Indicators were based on an evidence-based guideline for physiotherapy in PD. Guideline recommendations were transformed into indicators and rated for their relevance by an expert panel. Relevant indicators were incorporated into a questionnaire termed ''Quality Indicators for Physiotherapy in PD'' (QIP-PD). The QIP-PD was piloted among 105 physiotherapists. The adjusted version was evaluated in 46 physiotherapists with specific expertise in PD and in 795 general physiotherapists. The following clinimetric aspects of the QIP-PD were tested: completeness of answers, response distribution, internal consistency, and discriminative power. The reliability of the QIP-PD was evaluated by interviews among a randomly selected cohort of 32 PD experts and 32 general physiotherapists. RESULTS: The expert panel selected 16 indicators, which were transformed into an adjusted 17-item QIP-PD. The adjusted QIP-PD was completed by 41 expert physiotherapists and 286 general physiotherapists. Comple-teness of item scores ranged from 95-98%. Six items were excluded from the final analyses as they showed ceiling effect among both groups, or lacked discriminative power. The total QIP-PD score for the 11 items was significantly higher for expert physiotherapists (35.1+/-4.2) compared to general physiotherapists (22.2+/-7.7; P=0.01). Internal consistency was good (Crohnbach's alpha 0.84). QIP-PD scores of therapists and interviewers (correlated using Intraclass Correlations Coefficients) ranged from 0.63 to 0.75. CONCLUSIONS: The QIP-PD is a relevant, feasible, valid, discriminative and reliable instrument to measure adherence to guidelines for physiotherapy in PD. In addition, the results underscore that quality improvement interventions for physiotherapy in PD are needed, as guideline adherence is suboptimal in physiotherapists without specific PD expertise.
