Effectiveness and costs of specialised physiotherapy given via ParkinsonNet: a retrospective analysis of medical claims data

Specialized Allied Health Care for Parkinson's Disease: State of the Art and Future Directions

People with Parkinson's disease (PD) experience a range of progressive motor and non-motor symptoms, that negatively affect their daily functioning, social participation and quality of life. Allied health therapies have emerged as an effective treatment approach-complementary to pharmacological and neurosurgical treatments-which reduces the impact of PD in daily life. In this article, we propose criteria for what constitutes specialized allied health care for PD, and we review allied health research in PD in terms of meeting these criteria and its outcomes for monodisciplinary approaches as well as multi- or interdisciplinary allied health interventions. We focus on the three most studied allied health disciplines in PD: physical therapy, occupational therapy and speech-language therapy. Overall, the available evidence underscores the importance and potential benefits of specialized allied health care for people with PD. Our proposed criteria and recommendations for future research might help in further delineating specialized allied health care.

Survey of the Knowledge, Attitudes, and Practices of Neurologists Regarding Exercise in Parkinson's Disease

BACKGROUND AND PURPOSE

Exercise and physiotherapy can exert potentially beneficial effects on the motor and nonmotor features of Parkinson's disease (PD). We conducted an e-mail survey to assess the knowledge, attitudes, and practices of neurologists regarding exercise among patients with PD.

METHODS

A total of 222 neurologists from the Korean Movement Disorder Society and the Korean Society of Neurologists completed the survey and were classified into 4 clusters using the k-means clustering algorithm based on their institute types, the proportions of PD patients in their clinics, and the number of years working as neurologists.

RESULTS

Specialists working at referral hospitals (Clusters 1 and 2) were more confident than general neurologists (Clusters 3 and 4) about exercise improving the general motor features of PD. Specialists recommended more-frequent intense exercise compared with physicians not working at referral hospitals. The specialists in Cluster 1, representing >50% of PD patients in the clinics at referral hospitals, recommended exercise regardless of the disease stage, whereas the general neurologists in Clusters 3 and 4 recommended low-intensity exercise at an early stage of disease. Although most of the respondents agreed with the need for PD patients to exercise, less than half had prescribed rehabilitation or physiotherapy. More than 90% of the respondents answered that developing an exercise/physiotherapy protocol for PD would be helpful.

CONCLUSIONS

Specialists were more confident than general neurologists about the effect of exercise and recommended more-intense activities regardless of the disease stage. These results highlight the need to develop clinical practice guidelines and PD-specialized exercise protocols to provide optimal care for PD patients.

[Multidisciplinary Complex Treatment of Parkinson's disease : Cornerstone of an individualized treatment]

BACKGROUND

The inpatient Parkinson's disease multimodal complex treatment (PD-MCT) was applied more than 15,000 times in 2022, in Germany. This number is increasing as is Parkinson's disease (PD), which affects more than 400,000 people in Germany and leads to 100,000 disability-adjusted life years. In recent years, several observational studies have been conducted on the effectiveness of this kind of multidisciplinary care.

OBJECTIVE

To summarize and discuss the evidence on the nature, benefits and potential of PD-MCT.

METHODS

A narrative review of selected empirical findings was carried out.

RESULTS

The PD-MCT frequently lasts for 2-3 weeks and aims to maintain the quality of life of people with PD. Disease symptoms and activities of daily living are jointly improved by pharmacological strategies and activating therapies (physiotherapy, occupational therapy, speech and language therapy, physical training, art therapy). The PD-MCT is a useful measure to avoid or mitigate crisis situations in the course of the disease. A total of eight observational studies (n = 1246) have shown good effectiveness with a total mean improvement of the International Parkinson and Movement Disorder Society unified Parkinson's disease rating scale III (MDS-UPDRS III) by 7.8 points. The transfer of effects into everyday life through intensive and specialized community-based care must be ensured in order to achieve sustained effects on the quality of life. Ideally, this transfer can be supported by integrated PD networks and digital technologies in the future.

CONCLUSION

There is potential for development in the standardization, patient selection and quality assurance of PD-MCT as well as in the embedding in care structures such as PD networks. Open research questions include a precise definition of the target group and higher quality evidence of short-term and long-term effectiveness.

Structured medication reviews in Parkinson's disease: pharmacists' views, experiences and needs - a qualitative study

Background

Executing structured medication reviews (SMRs) in primary care to optimize drug treatment is considered standard care of community pharmacists in the Netherlands. Patients with Parkinson's disease (PD) often face complex drug regimens for their symptomatic treatment and might, therefore, benefit from an SMR. However, previously, no effect of an SMR on quality of life in PD was found. In trying to improve the case management of PD, it is interesting to understand if and to what extent SMRs in PD patients are of added value in the pharmacist's opinion and what are assumed facilitating and hindering factors.

Objectives

To analyse the process of executing SMRs in PD patients from a community pharmacist's point of view.

Design

A cross-sectional, qualitative study was performed, consisting of face-to-face semi-structured in-depth interviews.

Methods

The interviews were conducted with community pharmacists who executed at least one SMR in PD, till data saturation was reached. Interviews were transcribed verbatim, coded and analysed thematically using an iterative approach.

Results

Thirteen pharmacists were interviewed. SMRs in PD were considered of added value, especially regarding patient contact and bonding, individualized care and its possible effect in the future, although PD treatment is found already well monitored in secondary care. Major constraints were time, logistics and collaboration with medical specialists.

Conclusion

Although community pharmacist-led SMRs are time-consuming and sometimes logistically challenging, they are of added value in primary care in general, and also in PD, of which treatment occurs mainly in secondary care. It emphasizes the pharmacist's role in PD treatment and might tackle future drug-related issues. Improvements concern multidisciplinary collaboration for optimized SMR execution and results.

Effects of Group Exercise on Motor Function and Mobility for Parkinson Disease: A Systematic Review and Meta-Analysis

OBJECTIVE

Parkinson disease (PD) is associated with a predictable decline in motor function and mobility that is commonly managed with exercise. There is a limited understanding of the effects of group exercise compared to individual exercise (IE) and usual care (UC) on motor function and mobility. Our purpose was to investigate the effects of group exercise compared to IE and UC on motor function and mobility for people with PD.

METHODS

A systematic review and meta-analysis was performed with randomized control trials that investigated the effects of group compared with IE and UC on motor function and mobility for people with PD. A systematic search was performed in PubMed, EBSCO, and Science Direct databases. Methodological quality was assessed using the Cochrane Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Twenty-three studies assessed at least 1 mobility-related outcome measure, met our inclusion criteria, and were included in quantitative analysis. There was no significant difference on motor function and mobility between group exercise and IE for all standardized outcome assessment meta-analyses. Motor function and mobility were significantly improved with group exercise compared to UC in 9 of 11 standardized outcome assessment meta-analyses. Results were based upon low to moderate quality of evidence.

CONCLUSION

Based upon low to moderate quality of evidence, group exercise has a similar to larger effect as IE and UC on improving motor function and mobility for people with PD. When used in combination with skilled physical therapy, group exercise may be an appropriate adjunct to individualized physical therapy to maximize mobility and function.

IMPACT

Long-term adherence to exercise is essential to maintain mobility and motor function for people with PD. Our study suggests group exercise is as effective as IE and may be an appropriate option to encourage long-term adherence related to increased access, socialization, and accountability.

The mechanistic effects of acupuncture in rodent neurodegenerative disease models: a literature review

Neurodegenerative diseases refer to a battery of medical conditions that affect the survival and function of neurons in the brain, which are mainly presented with progressive loss of cognitive and/or motor function. Acupuncture showed benign effects in improving neurological deficits, especially on movement and cognitive function impairment. Here, we reviewed the therapeutic mechanisms of acupuncture at the neural circuit level in movement and cognition disorders, summarizing the influence of acupuncture in the dopaminergic system, glutamatergic system, γ-amino butyric acid-ergic (GABAergic) system, serotonergic system, cholinergic system, and glial cells at the circuit and synaptic levels. These findings can provide targets for clinical treatment and perspectives for further studies.

Exercise and physical activity promotion for people newly diagnosed with Parkinson's disease: a UK survey exploring current practice and the views of healthcare professionals

OBJECTIVES

Exercise and physical activity (PA) are increasingly recognized as important components in the management of Parkinson's disease (PD). Their promotion at diagnosis is essential for better management of symptoms and overall well-being. Healthcare professionals (HCPs) are pivotal to the promotion of exercise and PA, but there is limited guidance on the content of such interventions. This study describes current practice, and explores views of HCPs around PA and exercise promotion at diagnosis for people with PD (PwP) DESIGN: A cross-sectional study using an anonymous online survey.

PARTICIPANTS

HCPs working with PwP in the UK.

RESULTS

Twenty-nine doctors, 17 nurses and 106 physiotherapists completed the survey. All nurses, 99% of physiotherapists and 72% of doctors reported that they always promote exercise and PA during clinic appointments. HCPs identified how PA impacts PD symptoms, evidence on the role of exercise, and signposting to support groups as core topics in PA promotion for PwP. However, these topics are mainly addressed during physiotherapy appointments. Referrals to physiotherapy occur most frequently when PwP experience falls or mobility issues, rather than at diagnosis. HCPs (52% doctors and 41% of nurses) identified lack of confidence as a barrier to prescribing exercise to PwP.

CONCLUSION

The importance of promoting PA at diagnosis is widely acknowledged by HCPs. There are variations between disciplines in terms of the tools used, and the timing and duration of interventions. Previously identified barriers to exercise promotion were also found in this study, and should be explored further in order to aid the implementation of effective interventions.

Exercise as medicine in Parkinson's disease

Parkinson's disease (PD) is an incurable and progressive neurological disorder leading to deleterious motor and non-motor consequences. Presently, no pharmacological agents can prevent PD evolution or progression, while pharmacological symptomatic treatments have limited effects in certain domains and cause side effects. Identification of interventions that prevent, slow, halt or mitigate the disease is therefore pivotal. Exercise is safe and represents a cornerstone in PD rehabilitation, but exercise may have even more fundamental benefits that could change clinical practice. In PD, the existing knowledge base supports exercise as (1) a protective lifestyle factor preventing the disease (ie, primary prevention), (2) a potential disease-modifying therapy (ie, secondary prevention) and (3) an effective symptomatic treatment (ie, tertiary prevention). Based on current evidence, a paradigm shift is proposed, stating that exercise should be individually prescribed as medicine to persons with PD at an early disease stage, alongside conventional medical treatment.

Epidemiology of Limb Amputations and Prosthetic Use During COVID-19 Pandemic in the Netherlands

OBJECTIVE

To evaluate the trends in the incidence of major limb amputations and the prevalence of Dutch prosthetic users at the national level in The Netherlands between 2012 and 2021 (during the COVID-19 pandemic). Local hospitals in The Netherlands reported a doubling of major lower limb amputations during COVID-19, information about a change in the incidence of major upper limb amputations was not reported. We could not confirm this remarkable increase in major lower limb amputations in our institution, nor did we observe a change in the incidence of major upper limb amputations. We hypothesize that the COVID-19 pandemic had no effect on the number of major limb amputations.

DESIGN

Observational retrospective study analyzing national open-access databases of health insurance claims.

SETTING

The Dutch national opensource database www.opendisdata.nl was used to retrieve the incidence of limb amputations in the period 2012-2021, stratified by the level of amputation and the cause of amputation. The results were verified using the www.gipdatabank.nl databank. This period included 4 intervals of nationwide COVID-19 lockdowns.

PARTICIPANTS

60,848 patients who underwent limb amputations at the upper or lower extremity in the Netherlands from 2012 to 2021 (N=60,848) were included in this study.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Upper- and lower-limb amputation and prosthetic use.

RESULTS

Data were retrieved for a total of 60,848 patients in the Netherlands, who underwent 68,180 amputations of the upper and lower extremities at any level from 2012 to 2021, including 22,095 major amputations of the lower extremities. The ongoing trend of stable numbers of major lower-limb amputations from 2012 to 2019 continued in 2020 and 2021. The verification of these data at the level of prosthetic users confirmed that the annual trends were unchanged.

CONCLUSION

The reported increased numbers of major lower-limb amputations during the COVID-19 pandemic in the Netherlands could not be confirmed using nationwide epidemiologic data.

Interdisciplinary network care collaboration in Parkinson's disease: a baseline evaluation in Germany

BACKGROUND

The strengthening of interdisciplinary care collaboration in Parkinson's disease is taking on increasing importance in daily medical routine. Therefore, care providers worldwide are organizing themselves in disease-specific regional network structures. However, the existing networks are heterogeneous, and the driving key players are yet unidentified.

OBJECTIVES

To systematically identify key factors of the composition of health care professionals, who are initially interested in the development of a Parkinson network for interdisciplinary care collaboration, their motivation, and expectations, we conducted a basic evaluation in three different German regions covering a total number of 23,405 people with Parkinson's.

METHODS

A specially developed semi-open questionnaire focusing on socio-demographic information, ways of contact, interdisciplinary collaboration, and connectedness was used. Statistical analyses were performed based on a predesigned codebook.

RESULTS

The most crucial professions were outpatient therapists (physio-, occupational-, speech therapists) (36.7%), average case load of 10.1 patients/3 months and inpatient movement disorder specialists (21.1%), average case load of 197.4 patients/3 months. Before implementation of PD networks, 48.9% of outpatient therapists did not have any contact with neurologists. 58.9% of caregivers considered the current frequency of collaboration to be insufficient. The lack of political support as well as a lack of time were identified as main hurdles to increased collaboration.

CONCLUSION

The identified driving forces in strengthened care collaboration are assigned to different healthcare sectors. This makes networks which provide tools for specialized education and interdisciplinary, cross-sectoral communication indispensable. For an areawide rollout, a rethinking of political frameworks towards network care is strongly necessary.

Parkinson's Disease Is Predominantly an Environmental Disease

Parkinson's disease is the world's fastest growing brain disorder, and exposure to environmental toxicants is the principal reason. In this paper, we consider alternative, but unsatisfactory, explanations for its rise, including improved diagnostic skills, aging populations, and genetic causes. We then detail three environmental toxicants that are likely among the main causes of Parkinson's disease- certain pesticides, the solvent trichloroethylene, and air pollution. All three environmental toxicants are ubiquitous, many affect mitochondrial functioning, and all can access humans via various routes, including inhalation and ingestion. We reach the hopeful conclusion that most of Parkinson's disease is thus preventable and that we can help to create a world where Parkinson's disease is increasingly rare.

Clair KA, Toledo S, York MK, Todaro R, Yarab N, Wallock K. Delivering Multidisciplinary Rehabilitation Care in Parkinson's Disease: An International Consensus Statement

BACKGROUND

Parkinson's disease (PD) is a complex neurodegenerative disorder impacting everyday function and quality of life. Rehabilitation plays a crucial role in improving symptoms, function, and quality of life and reducing disability, particularly given the lack of disease-modifying agents and limitations of medications and surgical therapies. However, rehabilitative care is under-recognized and under-utilized in PD and often only utilized in later disease stages, despite research and guidelines demonstrating its positive effects. Currently, there is a lack of consensus regarding fundamental topics related to rehabilitative services in PD.

OBJECTIVE

The goal of the international Parkinson's Foundation Rehabilitation Medicine Task Force was to develop a consensus statement regarding the incorporation of rehabilitation in PD care.

METHODS

The Task Force, comprised of international multidisciplinary experts in PD and rehabilitation and people directly affected by PD, met virtually to discuss topics such as rehabilitative services, existing therapy guidelines and rehabilitation literature in PD, and gaps and needs. A systematic, interactive, and iterative process was used to develop consensus-based statements on core components of PD rehabilitation and discipline-specific interventions.

RESULTS

The expert-based consensus statement outlines key tenets of rehabilitative care including its multidisciplinary approach and discipline-specific guidance for occupational therapy, physical therapy, speech language pathology/therapy, and psychology/neuropsychology across all PD stages.

CONCLUSIONS

Rehabilitative interventions should be an essential component in the comprehensive treatment of PD, from diagnosis to advanced disease. Greater education and awareness of the benefits of rehabilitative services for people with PD and their care partners, and further evidence-based and scientific study are encouraged.

Delivery of Allied Health Therapies to People with Parkinson's Disease in Africa

Allied health therapies refer to a range of healthcare professionals, including physiotherapists, occupational and speech-language therapists, who aim to optimize daily function and quality of life in conjunction with medical care. In this narrative review of literature on allied health therapies in people with Parkinson's disease (PD), we focused on the diversity in healthcare access, state of the art, current challenges in the African continent, and proposed solutions and future perspectives. Despite the increasing prevalence and awareness of PD in Africa, numerous challenges persist in its management. These include resource limitations, geographical barriers, sociocultural beliefs, and economic constraints. Nevertheless, innovative solutions, including telerehabilitation and community-based rehabilitation, offer hope. Collaborative efforts within the continent and internationally have shown potential in bridging training and resource gaps. Significant strides can be made with tailored interventions, technological advancements, and multifaceted collaborations. This review offers practical insights for healthcare professionals, policymakers, and caregivers to navigate and optimize PD care in the African context.

Implementation and the effects of a Parkinson Network Therapy (PaNTher) on activities of daily living and health-related quality of life in Parkinson's disease patients: study protocol of an mixed-method observational cohort study in outpatient care

INTRODUCTION

Parkinson's disease (PD) represents the fastest growing neurodegenerative disease with an increasing prevalence worldwide. It is characterised by complex motor and non-motor symptoms that lead to considerable disability. Specialised physiotherapy has been shown to benefit patients with PD. The Parkinson Netzwerk Therapie (PaNTher) was created to improve access to specialised physiotherapy tailored to care priorities of PD patients. This study aims to evaluate the effectiveness, acceptability and needs of the PaNTher network by neurologists and physiotherapists involved in the network in outpatient care.

METHODS AND ANALYSIS

This is a mixed-method, prospective, pragmatic non-randomised cohort study of parallel groups, with data collection taking place in Bavaria, Germany, between 2020 and 2024. Patients with PD insured by the Allgemeine Ortskrankenkasse Bayern (AOK Bayern) living in Bavaria will be recruited for study participation by network partners. Patients in the intervention group must reside in Munich or the surrounding area to ensure provision of specialised physiotherapy in close proximity to their place of residence. Controls receive care as usual. Six and 12 months after baseline, all patients receive a follow-up questionnaire. Mixed-effect regression models will be used to examine changes in impairment of activities of daily living and quality of life of patients with PD enrolled in the programme over time compared with usual care. Qualitative interviews will investigate the implementation processes and acceptability of the PaNTher network among neurologists and physiotherapists. The study is expected to show that the PaNTher network with an integrative care approach will improve the quality and effectiveness of the management and treatment of patients with PD.

ETHICS AND DISSEMINATION

The study has been approved by the ethics committee at the medical faculty of the Ludwig-Maximilians-University Munich (20-318). Results will be published in scientific, peer-reviewed journals and presented at national and international conferences.

Experiences of health service access: A qualitative interview study of people living with Parkinson's disease in Ireland

BACKGROUND

People with Parkinson's disease (PD) do not always access specialist outpatient services in a timely manner in Ireland. The perspectives of people living with PD, relating to service access, are largely absent in the existing literature.

AIM

To explore experiences of PD service access for people living with PD, using a qualitative approach.

METHODS

Purposive maximum variation sampling was used. Semi-structured telephone interviews were conducted with 25 service users, including people with PD (n = 22) and supporting carers (n = 3). Informed consent was obtained from all participants. Interviews ranged in duration from 30 to 90 min. Data were managed in NVivo 12 and interpreted inductively using thematic analysis. The researchers were reflexive throughout the research process. The Consolidated Criteria for Reporting Qualitative Research checklist was employed to maximise transparency.

RESULTS

The findings highlight several key barriers to and facilitators of equitable and timely service access. Three key themes were identified comprising experiences of PD service access including 'geographical inequity', 'discriminatory practices', and 'public and private system deficits'. Together, these themes illustrate how a two-tiered and under-resourced health system lacks capacity, in terms of infrastructure and workforce, to meet PD needs for both public and private patients in Ireland.

CONCLUSIONS

These findings point to problems for PD care, relating to (i) how the health system is structured, (ii) the under-provision and under-resourcing of specialist outpatient PD services, including medical, nursing, and multidisciplinary posts, and (iii) insufficient PD awareness education and training across health settings. The findings also show that telemedicine can provide opportunities for making access to certain aspects of PD care more flexible and equitable, but the feasibility and acceptability of technology-enabled care must be assessed on an individual basis. Implications for policy, practice and research are discussed.

PATIENT OR PUBLIC CONTRIBUTION

The design and conduct of this study were supported by an expert advisory group (EAG) of 10 co-researchers living with PD. The EAG reviewed the interview schedule and the protocol for this study and provided detailed feedback from their perspective, to improve the methods, including the interview approach. The group also reviewed the findings of the study and contributed their insights on the meaning of the findings, which fed into this paper.

Exercise Made Accessible: the Merits of Community-Based Programs for Persons with Parkinson's Disease

PURPOSE OF REVIEW

Many studies have identified positive effects of physiotherapy and exercise for persons with Parkinson's disease (PD). Most work has thus far focused on the therapeutic modality of exercise as used within physiotherapy programs. Stimulated by these positive findings, there is now a strong move to take exercise out of the clinical setting and to deliver the interventions in the community. Although the goals and effects of many such community-based exercise programs overlap with those of physiotherapy, it has also become more clear that both exercise modalities also differ in various ways. Here, we aim to comprehensively review the evidence for community-based exercise in PD.

RECENT FINDINGS

Many different types of community-based exercise for people with PD are emerging and they are increasingly being studied. There is a great heterogeneity considering the types of exercise, study designs, and outcome measures used in research on this subject. While this review is positive regarding the feasibility and potential effects of community-based exercise, it is also evident that the general quality of these studies needs improvement. By focusing on community-based exercise, we hope to generate more knowledge on the effects of a wide range of different exercise modalities that can be beneficial for people with PD. This knowledge may help people with PD to select the type and setting of exercise activity that matches best with their personal abilities and preferences. As such, these insights will contribute to an improved self-management of PD.

Effects of DementiaNet's Community Care Network Approach on Admission Rates and Healthcare Costs: A Longitudinal Cohort Analysis

BACKGROUND

People with dementia are increasingly living at home, relying on primary care providers for most healthcare needs. Suboptimal collaboration and communication between providers could cause inefficiencies and worse patient outcomes. Innovative strategies are needed to address this growing disease burden and rising healthcare costs. The DementiaNet programme, a community care network approach targeted at patients with dementia in the Netherlands, has been shown to improve patient's quality of care. However, very little is known about the impact of DementiaNet on admission risks and healthcare costs. This study addresses this knowledge gap.

METHODS

A longitudinal cohort analysis was performed, using medical and long-term care claims data from 38 525 patients between 2015-2019. The primary outcomes were risk of hospital admission and annual total healthcare costs. Mixed-model regression analyses were used to identify changes in outcomes.

RESULTS

Patients who received care from a DementiaNet community care network showed a general trend in lower risk of admission for all types of admissions studied (ie, hospital, emergency ward, intensive care, crisis, and nursing home). Also, the intervention group showed a significant reduction of 12% in nursing days (relative risk [RR] 0.88; 95% CI: 0.77- 0.96). No significant differences were found for total healthcare costs. However, we found effects in two sub-elements of total healthcare costs, being a decrease of 19.7% (95% CI: 7.7%-30.2%) in annual hospital costs and an increase of 10.2% (95% CI: 2.3%-18.6%) in annual primary care costs.

CONCLUSION

Our study indicates that DementiaNet's community care network approach may reduce admission risks for patients with dementia over a long-term period of five years. This is accompanied by a decrease in nursing days and savings in hospital care that exceed increased primary care costs. This improvement in integrated dementia care supports wider scale implementation and evaluation of these networks.

Design and implementation of ParkinsonAKTIV: an interventional study to evaluate the effectiveness of a novel online platform to guide quickcard-based treatment decisions

INTRODUCTION

Patients with Parkinson's Disease (PD) require an all-encompassing and individualized care including pharmacological as well as non-pharmacological treatment approaches, such as physical therapy, occupational therapy and speech and swallowing therapy. ParkinsonAKTIV is an innovative, multidisciplinary, and comprehensive approach to guide this non-pharmacological PD treatment in northwestern Germany. Its online communication platform called JamesAKTIV has been developed to enhance and standardize PD healthcare professionals' communication. The implementation of ParkinsonAKTIV and JamesAKTIV is accompanied through a detailed process evaluation and to gather evidence on the impact on patient-related outcomes, such as health-related quality of life and healthcare costs for people with PD through an effectiveness evaluation.

METHODS

The study design contains two parts: (1) first, a quantitative effectiveness evaluation is conducted utilizing a prospective quasi-experimental approach with a control group which examines PD patient's health-related quality of life and physician-assessed PD patient's health status (Unified Parkinson Disease Rating Scale). Moreover, a health economic evaluation of the ParkinsonAKTIV intervention is conducted using patient-reported outcomes and cost data as well as routine data from a statutory health insurance. (2) Second, a mixed-methods process evaluation among healthcare professionals, which examines the feasibility and potential barriers and facilitators of ParkinsonAKTIV for routine care, is performed. Quantitative results from a social network analysis and a survey among healthcare professionals will be triangulated with data from qualitative stakeholder interviews and focus group discussions.

PERSPECTIVE

Findings are expected to provide evidence of an increase in quality of life of patients with PD, less severe PD symptoms, and a better ability to participate in activities of daily living. ParkinsonAKTIV has the potential of increasing PD patients' quality of care through sufficient and more tailored prescription of non-pharmacological therapies. It is anticipated that ParkinsonAKTIV will improve communication among health professionals. Results from the ParkinsonAKTIV study will provide first practice-oriented evidence and a roadmap for implementation of an online tool for a comprehensive, multidisciplinary care PD network for patients and their caregivers in routine care in Germany. Trial registration ClinicalTrials.gov: registration number NCT05251298 (retrospectively registered: https://clinicaltrials.gov/ct2/show/record/NCT05251298 ).

Beneficial Role of Vitexin in Parkinson's Disease

Today, Parkinson's disease (PD) is the foremost neurological disorder all across the globe. In the quest for a novel therapeutic agent for PD with a multimodal mechanism of action and relatively better safety profile, natural flavonoids are now receiving greater attention as a potential source of neuroprotection. Vitexin have been shown to exhibit diverse biological benefits in various disease conditions, including PD. It exerts its anti-oxidative property in PD patients by either directly scavenging reactive oxygen species (ROS) or by upregulating the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and enhancing the activities of antioxidant enzymes. Also, vitexin activates the ERK1/1 and phosphatidyl inositol-3 kinase/Akt (PI3K/Akt) pro-survival signalling pathway, which upregulates the release of anti-apoptotic proteins and downregulates the expression of pro-apoptotic proteins. It could be antagonistic to protein misfolding and aggregation. Studies have shown that it can also act as an inhibitor of monoamine oxidase B (MAO-B) enzyme, thereby increasing striatal dopamine levels, and hence, restoring the behavioural deficit in experimental PD models. Such promising pharmacological potential of vitexin could be a game-changer in devising novel therapeutic strategies against PD. This review discusses the chemistry, properties, sources, bioavailability and safety profile of vitexin. The possible molecular mechanisms underlying the neuroprotective action of vitexin in the pathogenesis of PD alongside its therapeutic potential is also discussed.

Understanding support systems for Parkinson's disease management in community settings: A cross-national qualitative study

BACKGROUND

Health and social care systems face difficulties in managing multimorbidity, disease burden and complex needs in long-term conditions such as Parkinson's disease.

OBJECTIVE

This study aimed to develop a European understanding of how health and social care professionals can collaborate with stakeholders from different organizations and sectors to enhance the management of Parkinson's disease in a community setting by identifying the existing gaps in this process and how people with Parkinson's disease and their family carers could benefit from these partnerships.

METHODS

A mixed-methods sequential study was conducted in Denmark, Norway, Spain and the United Kingdom. The findings from the qualitative phase are presented. Individual semistructured interviews were analysed using Braun's and Clarke's thematic analysis. A meta-ethnography approach was used to analyse and synthesize cross-national findings.

RESULTS

A total of 41 healthcare professionals and 39 stakeholders from different disciplines and sectors were interviewed in the four countries. The participants acknowledged a lack of awareness of available resources and poor communication between the different support systems in the management of Parkinson's disease. To promote multiagency collaborations, the participants highlighted the need to organize services along the Parkinson's disease journey, patient involvement and strategic involvement of carers in organizing resources and Parkinson's disease care pathways. According to the participants, the benefits from multiagency partnerships could lead to an enhanced continuity of care and specialized knowledge, mobilization of resources in the community, personalized support and improved access to services.

CONCLUSIONS

Policymakers are called upon to create formal structures that facilitate multisectoral collaborations to promote an integrated system of care for the management of Parkinson's disease in the community. To address this challenge, we propose five strategies showing how organizations can work together to optimize the use of resources and enhance the management of Parkinson's disease throughout the illness trajectory.

PATIENT OR PUBLIC CONTRIBUTION

Patient and Public Involvement groups made up of stakeholders, healthcare professionals, patients with Parkinson's disease and family carers participated in the design of the study, the development of the interview guides and the validation of the findings.

Time trends in demographic characteristics of participants and outcome measures in Parkinson's disease research: A 19-year single-center experience

Background

Females, people with young-onset PD and older individuals, and non-white populations are historically underrepresented in clinical Parkinson's disease (PD) research. Furthermore, research traditionally focused predominantly on motor symptoms of PD. Including a representative and diverse group of people with PD and also studying non-motor symptoms is warranted to better understand heterogeneity in PD and to generalize research findings.

Objective

This project aimed to determine whether, within a consecutive series of PD studies performed within a single center in the Netherlands: (1) the proportion of included females, mean age and proportion of native Dutch people changed over time; and 2) reports of the ethnicity of participants and the proportion of studies with non-motor outcomes changed over time.

Methods

Characteristics of participants and non-motor outcomes were analyzed using a unique dataset of summary statistics of studies with a large number of participants conducted at a single center during a 19-year period (2003-2021).

Results

Results indicate no relationship between calendar time and proportion of females (mean 39 %), mean age (66 years), proportion of studies that reported ethnicity, and proportion of native Dutch people in studies (range 97-100 %). The proportion of participants in whom non-motor symptoms were assessed increased, but this difference was consistent with chance.

Conclusion

Study participants in this center reflect the PD population in the Netherlands in terms of sex, but older individuals and non-native Dutch individuals are under-represented. We have still a lot to do in ensuring adequate representation and diversity in PD patients within our research.

Cost-utility analysis of a structured medication review compared to usual care in Parkinson's disease

PURPOSE

For controlling symptoms in Parkinson's disease (PD) together with treating additional comorbidities, patients often face complex medication regimens, with suboptimal adherence, drug-related problems, and diminished therapy efficacy as a common consequence. A medication review could potentially tackle these issues, among others by optimizing drug treatment. Even if no change in clinical outcomes is observed, this intervention might decrease health care costs by reducing drug-related problems and hospital admissions. This study aimed to gain more insight in the health benefits and costs of a structured medication review (SMR) in PD.

METHODS

A cost-utility analysis was performed, based on a multicenter randomized controlled trial with 202 PD patients with polypharmacy. The intervention group received an SMR, whereas the control group received usual care. The intervention effect after 6 months of follow-up was presented as incremental quality-adjusted life years (QALY) using the EQ-5D-5L questionnaire. Costs were based on real-world data. Missing data was imputed using multiple imputation techniques. Bootstrapping was used to estimate the uncertainty in all health and economic outcomes.

RESULTS

The QALY gain in the intervention group compared to the control group was - 0.011 (95% CI - 0.043; 0.020). Incremental costs were €433 (95% CI - 873; 1687). When adapting a willingness-to-pay threshold of €20,000/QALY and €80,000/QALY, the probability of SMRs being cost-effective was 18% and 30%, respectively.

CONCLUSION

A community pharmacist-led SMR in PD patients in the current setting shows no apparent benefit and is not cost-effective after 6 months, compared to usual care.

Specialized Versus Generic Allied Health Therapy and the Risk of Parkinson's Disease Complications

BACKGROUND

Specialized versus generic physiotherapy (PT) reduces Parkinson's disease (PD)-related complications. It is unclear (1) whether other specialized allied heath disciplines, including occupational therapy (OT) and speech and language therapy (S&LT), also reduce complications; (2) whether there is a synergistic effect among multiple specialized disciplines; and (3) whether each allied health discipline prevents specific complications.

OBJECTIVES

To longitudinally assessed whether the level of expertise (specialized vs. generic training) of PT, OT, and S&LT was associated with the incidence rate of PD-related complications.

METHODS

We used claims data of all insured persons with PD in the Netherlands between January 1, 2010, and December 31, 2018. ParkinsonNet-trained therapists were classified as specialized, and other therapists as generic. We used mixed-effects Poisson regression models to estimate rate ratios adjusting for sociodemographic and clinical characteristics.

RESULTS

The population of 51,464 persons with PD (mean age, 72.4 years; standard deviation 9.8) sustained 10,525 PD-related complications during follow-up (median 3.3 years). Specialized PT was associated with fewer complications (incidence rate ratio [IRR] of specialized versus generic = 0.79; 95% confidence interval, [0.74-0.83]; P < 0.0001), as was specialized OT (IRR = 0.88 [0.77-0.99]; P = 0.03). We found a trend of an association between specialized S&LT and a lower rate of PD-related complications (IRR = 0.88 [0.74-1.04]; P = 0.18). The inverse association of specialized OT persisted in the stratum, which also received specialized PT (IRR = 0.62 [0.42-0.90]; P = 0.001). The strongest inverse association of PT was seen with orthopedic injuries (IRR = 0.78 [0.73-0.82]; P < 0.0001) and of S&LT with pneumonia (IRR = 0.70 [0.53-0.93]; P = 0.03).

CONCLUSIONS

These findings support a wider introduction of specialized allied health therapy expertise in PD care and conceivably for other medical conditions. © 2022 The Authors. Movement Disorders published by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society.

[Parkinson's disease]

Parkinson's disease (PD) is an unparalleled example of a neurodegenerative disorder that can be effectively managed leading to sustained symptom control and quality of life. The cooperation of neurologists with general practitioners, gastroenterologists, and geriatricians is of increasing importance for an optimized management of PD. New diagnostic criteria for PD and for atypical Parkinsonism, which should be considered in the differential diagnostics, include non-motor symptoms and aim to diagnose these disorders as early as possible. Recent research has shown that there are highly complex and clinically relevant interactions with PD at all levels of the gastrointestinal tract, which have been increasingly better understood and have direct clinical relevance. Novel dopaminergic treatment approaches focus on circumvention of the impaired gastrointestinal tract of PD patients. The management of geriatric PD patients and PD dementia requires specific clinical knowledge. Worldwide, PD has emerged as a model disease for the development of network structures for the treatment of chronic neurological diseases.

HMGB1 is a Potential and Challenging Therapeutic Target for Parkinson's Disease

Parkinson's disease (PD) is one of the most common degenerative diseases of the human nervous system and has a wide range of serious impacts on human health and quality of life. Recently, research targeting high mobility group box 1 (HMGB1) in PD has emerged, and a variety of laboratory methods for inhibiting HMGB1 have achieved good results to a certain extent. However, given that HMGB1 undergoes a variety of intracellular modifications and three different forms of extracellular redox, the possible roles of these forms in PD are likely to be different. General inhibition of all forms of HMGB1 is obviously not ideal and has become one of the biggest obstacles in the clinical application of targeting HMGB1. In this review, pure mechanistic research of HMGB1 and in vivo research targeting HMGB1 were combined, the effects of HMGB1 on neurons and immune cell responses in PD are discussed in detail, and the problems that need to be focused on in the future are addressed.

Telemedicine in the Management of Parkinson's Disease: Achievements, Challenges, and Future Perspectives

BACKGROUND

As the global population grows, there is an increasing demand for neurologic consultation that prompts new ways to reach more patients. Telemedicine can provide an accessible, cost-effective, and high-quality healthcare services.

OBJECTIVES

In this article, we highlight recent developments, achievements, and challenges regarding outcomes, clinical care, tele-education, teletreatment, teleresearch, and cybersecurity for telemedicine applied to Parkinson´s disease (PD) and other neurological conditions.

RESULTS

A growing body of evidence supports the feasibility and effectiveness of telemedicine tools for PD and other movement disorders. Outcome variables regarding satisfaction and efficacy in clinical care and specific issues about education, research, and treatment are reviewed. Additionally, a specific legal framework for teleconsultation has been developed in some centers worldwide. Yet, the implementation of telemedicine is conditioned by the limitations inherent to remote neurological examination, the variable computer usage literacy among patients, and the availability of a reliable internet connection. At present, telemedicine can be considered an additional tool in the clinical management of PD patients.

CONCLUSIONS

There is an increasing use of remote clinical practice regarding the management of PD and other neurological conditions. Telemedicine is a new and promising tool aimed at special settings and subpopulations.

Telehealth For Individuals with Parkinson's Disease During Covid-19 In Brazil: A Prospective Case Series

Objective

To implement a telerehabilitation prevention, treatment, and follow-up physical therapy protocol for monitoring individuals with Parkinson's disease (PD) and to verify its effectiveness in minimizing the deleterious effects of the COVID-19 pandemic.

Design

Prospective case series, involving 40 participants with mild to moderate PD recruited from a specialized neurorehabilitation group. The study was divided into four parts: (1) Phone calls to assess the feasibility of participating in remote physical therapy. (2) Social media training. (3) Baseline and post-intervention assessment for functional lower extremity strength, fear of falling, quality of life, depression, anxiety, activities of daily living, verbal fluency. (4) Intervention protocol consisting of 20 remote weekly physical therapy sessions, graphic material for physical and cognitive training, social activities, and education.

Conclusion

The telerehabilitation protocol was viable and effective for patients with PD as an alternative to in-person treatment during the COVID-19 pandemic.

Detection of primary Sjögren’s syndrome in primary care: developing a classification model with the use of routine healthcare data and machine learning

Background

Primary Sjögren’s Syndrome (pSS) is a rare autoimmune disease that is difficult to diagnose due to a variety of clinical presentations, resulting in misdiagnosis and late referral to specialists. To improve early-stage disease recognition, this study aimed to develop an algorithm to identify possible pSS patients in primary care. We built a machine learning algorithm which was based on combined healthcare data as a first step towards a clinical decision support system.

Method

Routine healthcare data, consisting of primary care electronic health records (EHRs) data and hospital claims data (HCD), were linked on patient level and consisted of 1411 pSS and 929,179 non-pSS patients. Logistic regression (LR) and random forest (RF) models were used to classify patients using age, gender, diseases and symptoms, prescriptions and GP visits.

Results

The LR and RF models had an AUC of 0.82 and 0.84, respectively. Many actual pSS patients were found (sensitivity LR = 72.3%, RF = 70.1%), specificity was 74.0% (LR) and 77.9% (RF) and the negative predictive value was 99.9% for both models. However, most patients classified as pSS patients did not have a diagnosis of pSS in secondary care (positive predictive value LR = 0.4%, RF = 0.5%).

Conclusion

This is the first study to use machine learning to classify patients with pSS in primary care using GP EHR data. Our algorithm has the potential to support the early recognition of pSS in primary care and should be validated and optimized in clinical practice. To further enhance the algorithm in detecting pSS in primary care, we suggest it is improved by working with experienced clinicians.

Density of Patient-Sharing Networks: Impact on the Value of Parkinson Care

BACKGROUND

Optimal care for Parkinson's disease (PD) requires coordination and collaboration between providers within a complex care network. Individual patients have personalised networks of their own providers, creating a unique informal network of providers who treat ('share') the same patient. These 'patient-sharing networks' differ in density, ie, the number of identical patients they share. Denser patient-sharing networks might reflect better care provision, since providers who share many patients might have made efforts to improve their mutual care delivery. We evaluated whether the density of these patient-sharing networks affects patient outcomes and costs.

METHODS

We analysed medical claims data from all PD patients in the Netherlands between 2012 and 2016. We focused on seven professional disciplines that are commonly involved in Parkinson care. We calculated for each patient the density score: the average number of patients that each patient's providers shared. Density scores could range from 1.00 (which might reflect poor collaboration) to 83.00 (which might reflect better collaboration). This score was also calculated at the hospital level by averaging the scores for all patients belonging to a specific hospital. Using logistic and linear regression analyses we estimated the relationship between density scores and health outcomes, healthcare utilization, and healthcare costs.

RESULTS

The average density score varied considerably (average 6.7, SD 8.2). Adjusted for confounders, higher density scores were associated with a lower risk of PD-related complications (odds ratio [OR]: 0.901; P<.001) and with lower healthcare costs (coefficients: -0.018, P=.005). Higher density scores were associated with more frequent involvement of neurologists (coefficient 0.068), physiotherapists (coefficient 0.052) and occupational therapists (coefficient 0.048) (P values all <.001).

CONCLUSION

Patient sharing networks showed large variations in density, which appears unwanted as denser networks are associated with better outcomes and lower costs.

Community Exercise: A New Tool for Personalized Parkinson’s Care or Just an Addition to Formal Care?

Physiotherapy and exercise are associated with motor and non-motor benefits in Parkinson’s disease (PD). Community exercise programs may increase ongoing exercise participation and help people with Parkinson’s disease actively participate in their health management. But there is still limited knowledge about these programs regarding their benefits, safety, implications over the long-term, and effective implementation. These questions could hold relevant clinical implications. In this perspective article, we identify the current challenges and reflect upon potential solutions to help community exercise to be implemented as an additional anchor to personalize management models for Parkinson’s disease.

Neuropsychiatric Treatments for Parkinson's Disease: Nonpharmacological Approaches

Although diagnosed by characteristic motor features, Parkinson's disease and other movement disorders are frequently accompanied by a wide range of neuropsychiatric symptoms that require a multidisciplinary approach for treatment. Neuropsychiatric symptoms such as depression, anxiety and cognitive symptoms strongly influence quality of life, motor symptoms, and non-motor bodily symptoms. This review summarizes our current understanding of the neuropsychiatric symptoms in movement disorders and discusses the evidence base for treatments focusing on rehabilitation and nonpharmacological approaches. A practical approach is then proposed for patient selection for specific treatments based on disease stage. The article focuses mostly on Parkinson's disease as a prototypical movement disorder with the largest evidence base but the principles discussed herein are applicable to a range of other movement disorders.

Professionals' Self-Reported Difficulties towards Integrating Dual Task Training in Care for People with Parkinson's Disease

Background: Despite the growing use of dual task training (DTT) in clinical practice with people with Parkinson Disease (PD), there is still limited evidence on how to best implement it. Data regarding professionals’ difficulties when integrating such practices are critical as a first step to generate further guidance on how to apply it. The aim of this study was to identify the difficulties perceived by professionals to integrate dual task in their practice. Methods: A descriptive, observational and cross-sectional study was conducted using a web-based survey. Convenience sampling was used to recruit exercise and healthcare professionals working with people with PD through various social media channels. Data were collected and then analyzed thematically using the method of constant comparisons. The study report follows the consolidated criteria for reporting qualitative research (COREQ) checklist. Results: Of the 205 eligible responses, 68.8% were Physiotherapist. The majority of the participants reported having Parkinson-specific training (91.7%) and 59.0% applied DTT in individual one-on-one sessions. We identified ten categories of difficulties faced by professionals. Conclusions: Professionals struggle to integrate DTT into PD clinical care. Challenges were identified and the most significant refer to difficulties in managing the chronicity of the disease and lack of patient compliance with home exercises. Understanding current challenges towards dual task exercise will help to reflect upon strategies to be applied effectively and safe.

Physical Therapist Management of Parkinson Disease: A Clinical Practice Guideline From the American Physical Therapy Association

A clinical practice guideline on Parkinson disease was developed by an American Physical Therapy Association volunteer guideline development group that consisted of physical therapists and a neurologist. The guideline was based on systematic reviews of current scientific and clinical information and accepted approaches for management of Parkinson disease. The Spanish version of this clinical practice guideline is available as a supplement (Suppl. Appendix 1).

Barriers and Motivators to Engage in Exercise for Persons with Parkinson's Disease

Exercise is increasingly being recognized as a key element in the overall management of persons living with Parkinson’s disease (PD) but various (disease-specific) barriers may impede even motivated patients to participate in regular exercise. We aimed to provide a comprehensive review of the various barriers and motivators for exercise in persons with PD. We scrutinized data on compliance-related factors published in cross-sectional studies, randomized controlled trials and reviews. We classified the barriers and motivators to exercise from a patient perspective according to the International Classification of Functioning, Disability and Health. We present an overview of the large range of potential motivators and barriers for exercise in persons with PD. Healthcare professionals should consider a wide and comprehensive range of factors, in order to identify which specific determinants matter most for each individual. Only when persons with PD are adequately motivated in a way that appeals to them and after all person-specific barriers have been tackled, we can begin to expect their long-term adherence to exercise. Such long-term compliance will be essential if exercise is to live up to its expectations, including the hope that prolonged engagement in regular exercise might help to modify the otherwise relentlessly progressive course of PD.

Feasibility of a home-based interdisciplinary rehabilitation program for patients with Post-Intensive Care Syndrome: the REACH study

BACKGROUND

Survivors of critical illness experience long-term functional challenges, which are complex, heterogeneous, and multifactorial in nature. Although the importance of rehabilitation interventions after intensive care unit (ICU) discharge is universally recognized, evidence on feasibility and effectiveness of home-based rehabilitation programs is scarce and ambiguous. This study investigates the feasibility of an interdisciplinary rehabilitation program designed for patients with Post-Intensive Care Syndrome (PICS) who are discharged home.

METHODS

A mixed method, non-randomized, prospective pilot feasibility study was performed with a 6-month follow-up, comparing the intervention (REACH) with usual care. REACH was provided by trained professionals and included a patient-centered, interdisciplinary approach starting directly after hospital discharge. Primary outcomes were patient safety, satisfaction, adherence, referral need and health care usage. Secondary outcomes, measured at 3 timepoints, were functional exercise capacity, self-perceived health status, health-related quality of life (HRQoL), return to work and psychotrauma. Risk of undernutrition was assessed at baseline.

RESULTS

43 patients with a median mechanical ventilation duration of 8 (IQR:10) days, were included in the study and 79.1% completed 6-month follow-up. 19 patients received the intervention, 23 received usual care. Groups were similar for gender distribution and ICU length of stay. No adverse events occurred. REACH participants showed higher satisfaction with treatment and reported more allied health professional visits, while the usual care group reported more visits to medical specialists. Qualitative analysis identified positive experiences among REACH-professionals related to providing state-of-the-art interventions and sharing knowledge and expertise within an interprofessional network. Similar recovery was seen between groups on all secondary outcomes, but neither group reached reference values for HRQoL at 6 months. Larger return to work rates were seen in the REACH group. Prevalence of undernutrition at hospital discharge was high in both groups (> 80%), warranting the need for careful tuning of physical therapy and nutritional interventions.

CONCLUSIONS

This study shows that providing early, home-based rehabilitation interventions for patients with PICS-related symptoms is feasible and perceived positively by patients and professionals. When provided in an interdisciplinary collaborative network state of the art, person-centered interventions can be tailored to individual needs potentially increasing patient satisfaction, adherence, and efficacy.

Rationale and design to evaluate the PRIME Parkinson care model: a prospective observational evaluation of proactive, integrated and patient-centred Parkinson care in The Netherlands (PRIME-NL)

BACKGROUND

Culminating evidence shows that current care does not optimally meet the needs of persons with parkinsonism, their carers and healthcare professionals. Recently, a new model of care was developed to address the limitations of usual care: Proactive and Integrated Management and Empowerment in Parkinson's Disease (PRIME Parkinson). From 2021 onwards, PRIME Parkinson care will replace usual care in a well-defined region in The Netherlands. The utility of PRIME Parkinson care will be evaluated on a single primary endpoint (parkinsonism-related complications), which reflects the health of people with parkinsonism. Furthermore, several secondary endpoints will be measured for four dimensions: health, patient and carer experience, healthcare professional experience, and cost of healthcare. The reference will be usual care, which will be continued in other regions in The Netherlands.

METHODS

This is a prospective observational study which will run from January 1, 2020 until December 31, 2023. Before the new model of care will replace the usual care in the PRIME Parkinson care region all baseline assessments will take place. Outcomes will be informed by two data sources. We will use healthcare claims-based data to evaluate the primary endpoint, and costs of healthcare, in all persons with parkinsonism receiving PRIME Parkinson care (estimated number: 2,000) and all persons with parkinsonism receiving usual care in the other parts of The Netherlands (estimated number: 48,000). We will also evaluate secondary endpoints by performing annual questionnaire-based assessments. These assessments will be administered to a subsample across both regions (estimated numbers: 1,200 persons with parkinsonism, 600 carers and 250 healthcare professionals).

DISCUSSION

This prospective cohort study will evaluate the utility of a novel integrated model of care for persons with parkinsonism in The Netherlands. We anticipate that the results of this study will also provide insight for the delivery of care to persons with parkinsonism in other regions and may inform the design of a similar model for other chronic health conditions.

Changes in Epidemiological Trends and Rehabilitation Usage in Neurological Diseases in Korea: Parkinson's Disease

Parkinson's disease (PD) is a neurodegenerative disorder characterized by typical motor symptoms such as resting tremor, bradykinesia, and rigidity, as well as non-motor manifestations, including psychiatric symptoms, autonomic dysfunction, and cognitive impairment. These symptoms induce a marked impact on functional independence in daily activities and quality of life in PD patients. Recent guidelines recommend adequate rehabilitation education and treatment from the early stages of PD, and rehabilitation has become part of standard care for PD. In Korea, the number of patients with PD has more than tripled over 15 years, from 39,265 in 2004 to 125,607 in 2019. However, the rehabilitation usage of PD patients has not changed remarkably, and it remains suboptimal in Korea compared to several developed countries, which have advanced and disseminated guidelines and implemented specialized care delivery systems for PD over the past 20 years. Additional efforts are warranted to provide adequate rehabilitation therapies for PD patients in Korea.

Parkinson's disease

Parkinson's disease is a recognisable clinical syndrome with a range of causes and clinical presentations. Parkinson's disease represents a fast-growing neurodegenerative condition; the rising prevalence worldwide resembles the many characteristics typically observed during a pandemic, except for an infectious cause. In most populations, 3-5% of Parkinson's disease is explained by genetic causes linked to known Parkinson's disease genes, thus representing monogenic Parkinson's disease, whereas 90 genetic risk variants collectively explain 16-36% of the heritable risk of non-monogenic Parkinson's disease. Additional causal associations include having a relative with Parkinson's disease or tremor, constipation, and being a non-smoker, each at least doubling the risk of Parkinson's disease. The diagnosis is clinically based; ancillary testing is reserved for people with an atypical presentation. Current criteria define Parkinson's disease as the presence of bradykinesia combined with either rest tremor, rigidity, or both. However, the clinical presentation is multifaceted and includes many non-motor symptoms. Prognostic counselling is guided by awareness of disease subtypes. Clinically manifest Parkinson's disease is preceded by a potentially long prodromal period. Presently, establishment of prodromal symptoms has no clinical implications other than symptom suppression, although recognition of prodromal parkinsonism will probably have consequences when disease-modifying treatments become available. Treatment goals vary from person to person, emphasising the need for personalised management. There is no reason to postpone symptomatic treatment in people developing disability due to Parkinson's disease. Levodopa is the most common medication used as first-line therapy. Optimal management should start at diagnosis and requires a multidisciplinary team approach, including a growing repertoire of non-pharmacological interventions. At present, no therapy can slow down or arrest the progression of Parkinson's disease, but informed by new insights in genetic causes and mechanisms of neuronal death, several promising strategies are being tested for disease-modifying potential. With the perspective of people with Parkinson's disease as a so-called red thread throughout this Seminar, we will show how personalised management of Parkinson's disease can be optimised.

Is Aquatic Therapy Optimally Prescribed for Parkinson's Disease? A Systematic Review and Meta-Analysis

BACKGROUND

Aquatic therapy offers an alternative physiotherapy approach to managing the motor and non-motor symptoms associated with Parkinson's disease (PD).

OBJECTIVE

This review examined exercise prescription for aquatic therapy in PD and evaluated if aquatic therapy is as effective as land-based physiotherapy for improving movement, disability and wellbeing in people living with PD.

METHODS

A systematic search of eight databases was conducted to identify suitable randomized controlled trials from inception until August 2019. Aquatic therapy prescription data and outcomes of interest included gait, balance, motor disability, mobility, falls, mood, cognitive function and health related quality of life data was extracted and synthesised. A meta-analysis was performed where appropriate.

RESULTS

Fourteen studies involving 472 participants (Hoehn & Yahr scale I-IV) met the inclusion criteria. Eight were of modest quality, scoring 70-80% on the PEDro scale. Seven studies were included in the meta-analysis. Exercise prescription was highly variable and often insufficiently dosed. Similar gains were shown for aquatic therapy and land exercises for balance, motor disability or quality of life. A statistically significant difference was found for mobility as measured using the TUG (-1.5 s, 95 % CI -2.68 to -0.32; p = 0.01, I2 = 13%), in favor of aquatic therapy.

CONCLUSION

Aquatic therapy had positive outcomes for gait, balance and mobility that were comparable to land-based physiotherapy in the early stages of PD. The optimal dosage, content and duration of aquatic interventions for PD could not be confirmed in this meta-analysis. Many trials appeared to be under-dosed and therapy duration was low, ranging from 3-11 weeks.

Quadruple Decision Making for Parkinson's Disease Patients: Combining Expert Opinion, Patient Preferences, Scientific Evidence, and Big Data Approaches to Reach Precision Medicine

Clinical decision making for Parkinson’s disease patients is supported by a combination of three distinct information resources: best available scientific evidence, professional expertise, and the personal needs and preferences of patients. All three sources have clear value but also share several important limitations, mainly regarding subjectivity, generalizability and variability. For example, current scientific evidence, especially from controlled clinical trials, is often based on selected study populations, making it difficult to translate the outcome to the care for individual patients in everyday clinical practice. Big data, including data from real-life unselected Parkinson populations, can help to bridge this information gap. Fine-grained patient profiles created from big data have the potential to aid in identifying therapeutic approaches that will be most effective given each patient’s individual characteristics, which is particularly important for a disorder characterized by such tremendous interindividual variability as Parkinson’s disease. In this viewpoint, we argue that big data approaches should be acknowledged and harnessed, not to replace existing information resources, but rather as a fourth and complimentary source of information in clinical decision making, helping to represent the full complexity of individual patients. We introduce the ‘quadruple decision making’ model and illustrate its mode of action by showing how this can be used to pursue precision medicine for persons living with Parkinson’s disease.

Introduction of Network-Based Healthcare at Kaiser Permanente

Background:

Early 2014, Kaiser Permanente decided to adopt an innovative model for network-based allied healthcare for persons with Parkinson’s disease (PD), based on the principles of the Dutch ParkinsonNet.

Objective:

We present the interventions that were performed to implement this method at Kaiser Permanente and we show the first outcomes based on these interventions.

Methods:

In this study, 57 physical therapists, 18 speech therapists and 20 occupational therapists, as well as 13 medical centers across the state of California were included. Nine interventions were performed more or less simultaneously, including training and education of healthcare providers and patients, a train the trainer curriculum, organizing IT, streamlining referral processes and building networks.

Results:

At the start, less than 30% of the patients within the Southern California Region received specialized allied health treatment (consisting of, i.e., gait training, voice training or guidance in activities of daily life). After one year, almost 55% of patients received specialized allied health treatment. In the second year, this number increased to just under 67%, suggesting a sustained concentration of care (the second core component of networked care). This can be seen as a first indicator for successful implementation of the ParkinsonNet network at Kaiser Permanente.

Conclusions:

The importance of these findings lies in the fact that a healthcare innovation that proved effective in one country can be transferred successfully to another country and to another healthcare system.

The Architecture of Contemporary Care Networks for Rare Movement Disorders: Leveraging the ParkinsonNet Experience

In this paper, we present a universal model for implementing network care for persons living with chronic diseases, specifically those with rare movement disorders. Building on our longstanding experience with ParkinsonNet, an integrated care network for persons living with Parkinson's disease or a form of atypical parkinsonism, we provide a series of generic, supportive building blocks to (re)design comparable care networks. We discuss the specific challenges related to rare movement disorders and how these challenges can inform a tailored implementation strategy, using the basic building blocks to offer practical guidance. Lastly, we identify three main priorities to facilitate network development for these rare diseases. These include the clustering of different types of rare movement disorders at the network level, the implementation of supportive technology, and the development of interdisciplinary guidelines.

Analysis of nationwide multimodal complex treatment and drug pump therapy in Parkinson's disease in times of COVID-19 pandemic in Germany

INTRODUCTION

During the first peak phase of the COVID-19 pandemic, the German Ministry of Health recommended that elective treatments should be postponed to increase hospital capacities. This has also compromised the capacity for application of specialized Parkinson's disease (PD) therapies to an unknown extent.

METHODS

We conducted a nationwide cross-sectional study using administrative database of all hospitalized patients with main diagnosis of PD receiving multimodal complex treatment (PD-MCT), initial setup of levodopa/carbidopa intestinal gel (LCIG) or continuous subcutaneous apomorphine infusion (CSAI) in Germany. We compared case numbers and clinical characteristics of the pandemic (March 16th - May 15th, 2020) and post-lockdown (July 16th - September 15th, 2020) period with the pre-pandemic (January 16th - March 15th, 2020) and historical control period (March 16th - May 15th, 2019).

RESULTS

We identified a strong decline for PD-MCT(-62.8%) and for the application of drug pump-based therapies (-69.4%) during the first peak phase of the pandemic as compared to the pre-pandemic period while specialized PD treatment procedures increased again in the post-lockdown phase. Advanced disease was a marker for PD-MCT patients during the pandemic period.

CONCLUSION

Besides the marked decline in specialized PD treatments during the first peak phase of the COVID-19 pandemic, we found recuperative effects for these procedures in the post-lockdown period without reaching pre-pandemic levels. Strengthening treatment capacities for PD patients, even in the event of a persistent pandemic, is urgently needed in order to maintain the quality of care.

Efficacy of short-term multidisciplinary intensive rehabilitation in patients with different Parkinson's disease motor subtypes: a prospective pilot study with 3-month follow-up

Parkinson's disease (PD) can be classified into three motor-based subtypes: postural instability/gait difficulty (PIGD), tremor dominant (TD), and indeterminate. The neuropathophysiological mechanisms of the three motor subtypes are different, which may lead to different responses to therapy. Sixty-nine patients with idiopathic Parkinson's disease (Hoehn-Yahr stage ≤ 3) were screened from 436 patients with Parkinsonism recruited through outpatient services and the internet. According to the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) TD/PIGD ratio, the patients were divided into PIGD (TD/PIGD ≤ 0.09; n = 36), TD (TD/PIGD ≥1.15; n = 19), and indeterminate (TD/PIGD = 0.90-1.15; n = 14) groups. All patients received 2 weeks of multidisciplinary intensive rehabilitation treatment (MIRT) during hospitalization, as well as a remote home rehabilitation health education class. Compared with the scores at admission, all patients showed significant improvements in their MDS-UPDRS III score, walking ability, balance, and posture control at discharge. Moreover, the MDS-UPDRS III score improvement was greater in the PIGD group than in the TD group. The follow-up data, collected for 3 months after discharge, showed that overall symptom improvement in each group was maintained for 1-3 months. Furthermore, there were no significant differences in the duration or grade effects of symptom improvement among the three groups. These findings suggest that 2 weeks of MIRT is effective for improving motor performance in all three motor subtypes. Patients in the PIGD group had a better response after hospitalization than those in the TD group. This study was approved by the Institutional Ethics Committee of Beijing Rehabilitation Hospital of Capital Medical University of China (approval No. 2018bkky022) on May 7, 2018 and registered with the Chinese Clinical Trial Registry (registration No. ChiCTR1900020771) on January 19, 2019.

People with Parkinson's disease are more willing to do additional exercise if the exercise program has specific attributes: a discrete choice experiment

QUESTION

What specific attributes of exercise programs influence the preferences of people with Parkinson's disease for additional exercise compared with their current practice? What trade-offs are participants willing to make between exercise program attributes?

DESIGN

Discrete choice experiment.

PARTICIPANTS

Five hundred and forty people with Parkinson's disease.

INTERVENTION

Participants decided whether they would adopt a hypothetical program in addition to their current exercise routine.

OUTCOME MEASURES

Exercise program attributes included: type, number of sessions/week, location, travel time/session, delivery mode, supervisor's expertise, extent of supervision, benefits for physical and psychological function and out-of-pocket cost/session.

RESULTS

Participants preferred additional exercise when programs: provided physical (OR 1.85, 95% CI 1.61 to 2.13) or psychological (OR 1.45, 95% CI 1.26 to 1.67) benefit, involved less travel time (ORs 1.50 to 2.02) and were supervised by qualified professionals with Parkinson's disease expertise (ORs 1.51 to 1.91). Participants were most willing to add multimodal exercise to their exercise routine (ORs 2.01 to 2.19). Participants were less likely to prefer higher cost programs (OR 0.65, 95% CI 0.60 to 0.71, per AU$10 cost increase) or group sessions compared to individual sessions (OR 0.72, 95% CI 0.54 to 0.96). Men preferred adding strengthening exercises (OR 2.00, 95% CI 1.23 to 3.26) and women had a preference against adding aerobic exercise (OR 0.33, 95% CI 0.15 to 0.73). Participants not currently exercising were more likely to prefer adding exercise compared with those already exercising 300 minutes weekly (OR 1.74, 95% CI 1.15 to 2.63).

CONCLUSION

People with Parkinson's disease were more willing to participate in exercise programs that cost less, involve less travel, provide physical or psychological benefits and are supervised by qualified professionals. To enable more people with Parkinson's disease to exercise, health services should provide programs addressing these factors and account for sex differences.

From trials to clinical practice: Temporal trends in the coverage of specialized allied health services for Parkinson's disease

BACKGROUND AND PURPOSE

To determine how the coverage of specialized allied health services for patients with Parkinson's disease (PD) has developed in the Netherlands since the publication of trials that demonstrated cost-effectiveness.

METHODS

We used healthcare expenditure-based data on all insured individuals in the Netherlands to determine the annual proportion of patients with PD who received either specialized or generic allied health services (physiotherapy, occupational therapy, speech-language therapy) in 2 calendar years separated by a 5-year interval (2012 and 2017). Specialized allied health services were delivered through the ParkinsonNet approach, which encompassed professional training and concentration of care among specifically trained professionals.

RESULTS

Between 2012 and 2017, there was an increase in the number of patients with any physiotherapy (from 17,843 [62% of all patients with PD that year] to 22,282 [68%]), speech-language therapy (from 2171 [8%] to 3378 [10%]), and occupational therapy (from 2813 [10%] to 5939 [18%]). Among therapy-requiring patients, the percentage who were treated by a specialized therapist rose substantially for physiotherapy (from 36% in 2012 to 62% in 2017; χ²  = 2460.2; p < 0.001), speech-language therapy (from 59% to 85%; χ²  = 445.4; p < 0.001), and occupational therapy (from 61% to 77%; χ²  = 231.6; p < 0.001). By contrast, the number of patients with generic therapists did not change meaningfully. By 2017, specialized care delivery had extended to regions that had been poorly covered in 2012, essentially achieving nationwide coverage.

CONCLUSIONS

Following the publication of positive trials, specialized allied healthcare delivery was successfully scaled for patients with PD in the Netherlands, potentially serving as a template for other healthcare innovations for patients with PD elsewhere.

High-Intensity Interval Cycle Ergometer Training in Parkinson's Disease: Protocol for Identifying Individual Response Patterns Using a Single-Subject Research Design

Background: People with Parkinson's disease (PD) experience not only motor problems but also non-motor problems that seriously impede their daily functioning and quality of life. The current pharmacologic treatment of PD is symptomatic, and alternative rehabilitation treatments, which preferably also have a disease-modifying effect and promote neuroplasticity, are needed. Recent studies suggest that high-intensity interval training (HIIT) is promising for promoting neuroplasticity in human PD, with short training time and reduced burden. Biomarkers for neuroplasticity such as brain-derived neurotrophic factor (BDNF) and neurodegeneration (including neurofilament NfL and α-synuclein) may play a role, but their response to HIIT is not well-investigated.

Objectives: The aims of this study were (1) to study the effects of 4 weeks of HIIT compared with 4 weeks of continuous aerobic exercise on motor and non-motor outcomes of PD and (2) to investigate the association between HIIT, motor/non-motor performances changes, and blood biomarker levels for neuroplasticity and neurodegeneration.

Study Design: Single-subject research design with alternating treatment setup (ABACA) and frequent repeated measurements was used. Each participant received different intervention conditions (B/C) interspersed with baseline periods (A, i.e., ABACA or ACABA), and frequent repeated assessment of outcome measures is done to quantify within-subject, individual response patterns with sufficient power for data analysis. Blood samples were collected once a week in the baseline and training phases (A1 and B/C) and once every 2 weeks in the washout phases (A2 and A3).

Intervention: Four subjects with PD on stable dopaminergic medication, two in Hoehn–Yahr stage 1–2, and two in Hoehn–Yahr stage 2.5–3 followed an ABACA or ACABA schedule, consisting of blocks with 30-min sessions of “B” (HIIT) or 50-min sessions of “C” [continuous aerobic exercise (CAE)] 3×/week for 4 weeks, separated by baseline “A” periods of 8 weeks for a total duration of 28 weeks.

Outcome Measures: Outcome measures include disease status [Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS)], blood biomarkers (BDNF, Nfl, and α-synuclein), measures for functional mobility (including an activity tracker), and activities of daily living, as well as cognition, mood, biorhythm (sleeping problems), and quality of life.

Data Analysis: Visual analysis of trends in level, slope, and variability in response patterns was carried out, confirmed by longitudinal regression analysis with phase (ABACA) as the independent variable.

Health behaviors a year after an early intervention exercise and education program for people with Parkinson's disease

Aim: To evaluate the impact of an early intervention program on exercise behavior and mood in people with Parkinson's disease (PD) 1 year following participation. Patients & methods: Education and exercise program participants (n = 152) were followed up for 1 year. Changes in exercise behavior and mood and factors associated with these changes were examined. Results: At follow-up, 28% more participants exercised (p < 0.001). Changes in the proportion reporting depression (12% reduction; p = 0.10) or anxiety (4% increase, p = 0.09) were not statistically significant. Conclusion: An education and exercise program promoted positive exercise behavior change sustained for a year, supporting the importance of early intervention for people with PD. Future research should explore sustainable ways to encourage prolonged behavior change, including regular follow-up.
