Integrated care model for patients with functional somatic symptom disorder - a co-produced stakeholder exploration with recommendations for best practice. BMC Health Serv Res 2024; 24:698. [PMID: 38831287 PMCID: PMC11145802 DOI: 10.1186/s12913-024-11130-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 05/21/2024] [Indexed: 06/05/2024] Open
Abstract
BACKGROUND Functional somatic symptoms (FFS) and bodily distress disorders are highly prevalent across all medical settings. Services for these patients are dispersed across the health care system with minimal conceptual and operational integration, and patients do not currently access therapeutic offers in significant numbers due to a mismatch between their and professionals' understanding of the nature of the symptoms. New service models are urgently needed to address patients' needs and to align with advances in aetiological evidence and diagnostic classification systems to overcome the body-mind dichotomy. METHOD A panel of clinical experts from different clinical services involved in providing aspects of health care for patients with functional symptoms reviewed the current care provision. This review and the results from a focus group exploration of patients with lived experience of functional symptoms were explored by the multidisciplinary expert group, and the conclusions are summarised as recommendations for best practice. RESULTS The mapping exercise and multidisciplinary expert consultation revealed five themes for service improvement and pathway development: time/access, communication, barrier-free care, choice and governance. Service users identified four meta-themes for best practice recommendations: focus on healthcare professional communication and listening skills as well as professional attributes and knowledge base to help patients being both believed and understood in order to accept their condition; systemic and care pathway issues such as stronger emphasis on primary care as the first point of contact for patients, resources to reduce the length of the patient journey from initial assessment to diagnosis and treatment. CONCLUSION We propose a novel, integrated care pathway for patients with 'functional somatic disorder', which delivers care according to and working with patients' explanatory beliefs. The therapeutic model should operate based upon an understanding of the embodied nature of patient's complaints and provide flexible access points to the care pathway.

Abstract
BACKGROUND Previous studies exploring difficult inpatients have mostly focused on psychiatric inpatients. OBJECTIVE To explore the characteristics of difficult medicine inpatients. DESIGN Qualitative study using focus groups and semi-structured interviews. Transcripts were recorded, transcribed, and coded (MAXQDA) using thematic content analysis. PARTICIPANTS Medicine inpatient providers at a tertiary care facility. KEY RESULTS Our sample consisted of 28 providers (6 hospitalists, 10 medicine attendings, 6 medicine residents, and 6 interns). Theme 1: Provider experience: Difficult inpatients were time-consuming and evoked emotional responses including frustration and dysphoria. Theme 2: Patient characteristics: Included having personality disorders or mental health issues, being uncooperative, manipulative, angry, demanding, threatening, or distrustful. Difficult patients also had challenging social situations and inadequate support, unrealistic care expectations, were self-destructive, tended to split care-team messages, and had unclear diagnoses. Theme 3: Difficult families: Shared many characteristics of difficult patients including being distrustful, demanding, manipulative, threatening, or angry. Difficult families were barriers to care, disagreed with the treatment plan and each other, did not act in the patient's best interest, suggested inappropriate treatment, or had unrealistic expectations. STRATEGIES Approaches to dealing with difficult patients or families included building trust, being calm, and having a consistent message. Communication approaches included naming the emotion, empathetic listening, identifying patient priorities and barriers, and partnering. CONCLUSIONS Difficult patients induced emotional responses, dysphoria, and self-doubt among providers. Underlying personality disorders were often mentioned. Difficult patients and families shared many characteristics. Communication and training were highlighted as key strategies.

Abstract
Background: Literature points towards the potential benefits of the application of Eye Movement and Desensitization Processing (EMDR)-therapy for patients in the medical setting, with cancer and pain being among the domains it is applied to. The field of applying EMDR-therapy for patients treated in the medical setting has evolved to such an extent that it may be challenging to get a comprehensive overview.Objective: This systematic literature review aims to evaluate the use and effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy in patients treated in the medical setting.Methods: We performed a literature search following the PRISMA guidelines. Studies were included if the effectiveness of EMDR-therapy was assessed in adult patients treated in a medical setting. Excluded were patients exclusively suffering from a mental health disorder, without somatic comorbidity. A risk of bias analysis was performed. This review was registered on PROSPERO (CRD42022325238).Results: Eighty-seven studies, of which 26 (pilot)-RCTs were included and categorized in 14 medical domains. Additionally, three studies focusing on persistent physical complaints were included. Most evidence exists for its application in the fields of oncology, pain, and neurology. The overall appraisal of these studies showed at least moderate to high risks of bias. EMDR demonstrated effectiveness in reducing symptoms in 85 out of 87 studies. Notably, the occurrence of adverse events was rarely mentioned.Conclusions: Overall, outcomes seem to show beneficial effects of EMDR on reducing psychological and physical symptoms in patients treated in a medical setting. Due to the heterogeneity of reported outcomes, effect sizes could not be pooled. Due to the high risk of bias of the included studies, our results should be interpreted with caution and further controlled high-quality research is needed.

Gasquoine PG. Self-reported anterograde memory loss in older persons that is not validated on neuropsychological assessment: Considerations for a dissociative diagnosis. APPLIED NEUROPSYCHOLOGY.

Abstract
The past decade has witnessed amplified public awareness of age-related dementias. This has resulted in a dramatic rise in the number of older persons referred to memory clinics with a primary complaint of self-reported memory loss without an antecedent neurological event (e.g., stroke) who produce neuropsychological test profiles that lack evidence of such impairment. Since the latter part of the 19th century, a confusing array of changing terminology, criteria, and perceived causation have been ascribed to patients with unverified medical symptoms to implicate psychological causation. Such terms are often misperceived by laypersons as reflecting character flaws or malingering. Of import for clinical neuropsychologists, the 11th edition of the International Classification of Diseases added cognitive to symptoms eligible for a diagnosis of the modern formulation, dissociative neurological symptom disorder. One dissociative option for referrals with self-reported neurocognitive symptoms not validated on neuropsychological testing is functional memory disorder, conceived as a psychological disorder where emotional distress is plausibly related to the perceived memory loss but is of less severity than would warrant a major depressive or anxiety diagnosis. If evidence of psychological distress or behavioral impairment is not present the referral likely reflects the increased public awareness of age-related dementias interacting with the high base rate of self-perceived memory loss in the general population. In such cases, a dissociative diagnosis should be avoided as there is evidence of neither a medical nor a psychological disorder. A summary statement of not dementia or similar is likely sufficient to help the patient.

Abstract
BACKGROUND Functional somatic syndromes (FSSs), defined as chronic physical symptoms with no identifiable organic cause, may impact results after hip and knee arthroplasty. The purpose of this study was to perform a systematic review assessing the relationship between FSSs and clinical outcomes after primary total hip arthroplasty (THA), total knee arthroplasty (TKA), and unicompartmental knee arthroplasty (UKA). METHODS The PubMed and Web of Science databases were queried from January 1955 through December 2021 for studies investigating the impact of at least one FSS (fibromyalgia, irritable bowel syndrome (IBS), chronic headaches, and chronic low back pain) on outcomes after primary THA/TKA/UKA. Outcomes of interest included patient-reported outcome measures (PROMs), postoperative opioid use, complications, revisions, and costs of care. RESULTS There were twenty-eight studies, including 768,909 patients, of which 378,384 had an FSS. Five studies reported preoperative PROMs prior to THA/TKA, all of which showed worse PROMs among patients with at least 1 FSS diagnosis. Thirteen studies reported postoperative PROMs after THA/TKA, all of which demonstrated worse PROMs among patients with at least 1 FSS diagnosis. Patients with FSS diagnoses were more likely to continue using opioids at 3, 6, and 12 months following TKA, THA, and UKA. Medical and surgical complications, as well as revision rates, were higher among patients with FSSs. CONCLUSION Patients with FSSs have inferior PROMs and are at increased risk for prolonged postoperative opioid use, medical and surgical complications, and revision after hip and knee arthroplasty. Improved understanding of the factors influencing the success of hip and knee arthroplasty is critical. Future studies should address the biopsychosocial determinants of health that can impact outcomes after total joint arthroplasty.

Abstract
INTRODUCTION Appropriate treatment for people with an increased risk for developing chronic Persistent Somatic Symptoms (PSS) is of great importance at an early stage to improve quality of life and prevent high costs for society. OBJECTIVE To evaluate the cost-effectiveness of an integrated blended care intervention compared to usual care for QALYs, subjective symptom impact and physical and mental health status in patients with moderate PSS. METHODS This economic evaluation was conducted alongside a 12-month prospective, multicenter cluster randomized controlled trial in Dutch primary care. 80 participants received the intervention and 80 participants received usual care. Seemingly unrelated regression analyzes were performed to estimate cost and effect differences. Missing data were imputed using multiple imputation. Bootstrapping techniques were used to estimate uncertainty. RESULTS We found no significant difference in total societal costs. Intervention, primary and secondary healthcare and absenteeism costs were higher for the intervention group. The ICER for QALYs demonstrated the intervention was on average less costly and less effective compared to usual care. For the subjective symptom impact and physical health, the ICER indicated that the intervention group was on average less costly and more effective. For mental health, the intervention was on average more costly and less effective. CONCLUSION We didn't find an integrated blended primary care intervention to be cost-effective compared to usual care. However, when looking on relevant, but specific outcome measures (subjective symptom impact and physical health) for this population, average costs are found to be lower and the effectiveness found to be higher.

Abstract
Background Cognitive complaints are common in patients recovering from Coronavirus Disease 2019 (COVID-19), yet their etiology is often unclear. We assess factors that contribute to cognitive impairment in ambulatory versus hospitalized patients during the sub-acute stage of recovery. Methods In this cross-sectional study, participants were prospectively recruited from a hospital-wide registry. All patients tested positive for SARS-CoV-2 infection using a real-time reverse transcriptase polymerase-chain-reaction assay. Patients ≤ 18 years-of-age and those with a pre-existing major neurocognitive disorder were excluded. Participants completed an extensive neuropsychological questionnaire and a computerized cognitive screen via remote telemedicine platform. Rates of subjective and objective neuropsychological impairment were compared between the ambulatory and hospitalized groups. Factors associated with impairment were explored separately within each group. Results A total of 102 patients (76 ambulatory, 26 hospitalized) completed the symptom inventory and neurocognitive tests 24 ± 22 days following laboratory confirmation of SARS-CoV-2 infection. Hospitalized and ambulatory patients self-reported high rates of cognitive impairment (27–40%), without differences between the groups. However, hospitalized patients showed higher rates of objective impairment in visual memory (30% vs. 4%; p = 0.001) and psychomotor speed (41% vs. 15%; p = 0.008). Objective cognitive test performance was associated with anxiety, depression, fatigue, and pain in the ambulatory but not the hospitalized group. Conclusions Focal cognitive deficits are more common in hospitalized than ambulatory patients. Cognitive performance is associated with neuropsychiatric symptoms in ambulatory but not hospitalized patients. Objective neurocognitive measures can provide essential information to inform neurologic triage and should be included as endpoints in clinical trials.

Abstract
INTRODUCTION Persistent somatic symptoms (PSS) are highly prevalent in all areas of medicine; they are disabling for patients and costly for society. The subjective symptom burden often correlates poorly with the underlying disease severity, and patients' needs for effective treatment are far from being met. Initial evidence indicates that, in addition to disease-specific pathophysiological processes, psychological factors such as expectations, somatosensory amplification and prior illness experiences contribute to symptom persistence in functional as well as in somatic diseases. However, prospective studies investigating the transition from acute to chronic somatic symptoms, integrating pathophysiological, psychological and social factors, are scarce. A better understanding of the multifactorial mechanisms of symptom persistence is crucial for developing targeted mechanism-based interventions for effective prevention and treatment of PSS. Thus, the overall aim of the interdisciplinary SOMACROSS research unit is to identify generic and disease-specific risk factors and aetiological mechanisms of symptom persistence across a range of diseases. METHODS AND ANALYSIS Seven projects will investigate risk factors and mechanisms of symptom persistence in a total of 3916 patients across 10 medical conditions. All study designs are prospective and share common assessment points, core instruments and outcome variables to allow comparison and validation of results across projects and conditions. Research will focus on the identification of generic and disease-specific mechanisms associated with unfavourable symptom course. The development of a multivariate prediction model will facilitate the understanding of the course of PSS across diseases. ETHICS AND DISSEMINATION All individual SOMACROSS studies were approved by the ethics committees of the Medical Chambers Hamburg and Münster, Germany. Findings will be disseminated through peer-reviewed publications, scientific conferences and the involvement of relevant stakeholders, patients and the lay public. This interdisciplinary research unit will fundamentally contribute to earlier recognition of patients at risk, and to the development of prevention and tailored treatment concepts for PSS.

Abstract
ABSTRACT Nonpharmacological interventions are recommended for the treatment of fibromyalgia, but there is a lack of knowledge about the cost-effectiveness of these interventions. The aim of this study was to systematically review economic evaluations of educational, physical, and psychological interventions for the treatment of fibromyalgia. The search was performed in PUBMED, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database, PsycINFO, EconLit, National Health Service Economic Evaluation Database, and Health Technology Assessment. Economic evaluations of educational, physical, and psychological interventions for adult patients with fibromyalgia were included. Primary outcomes were healthcare and societal costs, and quality-adjusted life-years, and secondary outcomes were any disease-specific clinical outcome. Costs and effects were pooled in a meta-analysis, when possible. Eleven studies were included, of which 7 compared a psychological intervention with another intervention or usual care/control. Over a 6-month time horizon, healthcare and societal costs of the psychological intervention were significantly lower than usual care (mean difference: $-2087, 95% confidence interval [CI]: -3061 to -1112; mean difference: $-2411, 95% CI: -3582 to -1240, respectively), and healthcare costs were significantly lower for the psychological intervention compared with a pharmacological intervention (mean difference: $-1443, 95% CI: -2165 to -721). Over a 12-month time horizon, healthcare costs for the psychological intervention were significantly lower than for usual care (mean difference: $-538, 95% CI: -917 to -158). Incremental cost-effectiveness ratios for quality-adjusted life-years and impact of fibromyalgia showed that the psychological intervention was cost-effective compared with other interventions and control conditions. There is a need of more economic evaluations conducted alongside randomized controlled trials with interventions recommended for the treatment of fibromyalgia, such as physical exercise.

Abstract
We tested the efficacy of an integrative psychotherapeutic group treatment (IPGT) in reducing vertigo/dizziness-related impairment along with depression, anxiety, and somatization by conducting a randomized controlled superiority trial comparing IPGT to self-help groups moderated by a clinical psychologist (SHG). Adult patients with functional vertigo and dizziness symptoms were randomly allocated to either the IPGT or SHG as active control group. Outcomes were assessed at baseline (t0), after treatment lasting 16 weeks (t1), and 12 months after treatment (t2). A total of 81 patients were assigned to IPGT and 78 patients were assigned to SHG. Vertigo-related impairment was reduced in both conditions (IPGT: t0–t1: d = 1.10, t0–t2: d = 1.06; SHG: t0–t1: d = 0.86, t0–t2: d = 1.29), showing the efficiency of both IPGT and SHG. Clinically relevant improvements were also obtained for depression in both groups. Linear mixed model analyses revealed no differences between groups for all outcomes (effect of group for the primary outcome: b = −1.15, SE = 2.13, t = −0.54, p = 0.59). Attrition rates were higher in SHG (52.6%) than in IPGT (28.4%). Both conditions improved primary and secondary outcomes while IPGT was better accepted by patients than SHG.

Analysis of General Practitioners' Attitudes and Beliefs about Psychological Intervention and the Medicine-Psychology Relationship in Primary Care: Toward a New Comprehensive Approach to Primary Health Care. Healthcare (Basel) 2021; 9:healthcare9050613.

Abstract
The biopsychosocial paradigm is a model of care that has been proposed in order to improve the effectiveness of health care by promoting collaboration between different professions and disciplines. However, its application still faces several issues. A quantitative-qualitative survey was conducted on a sample of general practitioners (GPs) from Milan, Italy, to investigate their attitudes and beliefs regarding the role of the psychologist, the approach adopted to manage psychological diseases, and their experiences of collaboration with psychologists. The results show a partial view of the psychologist's profession that limits the potential of integration between medicine and psychology in primary care. GPs recognized that many patients (66%) would often benefit from psychological intervention, but only in a few cases (9%) were these patients regularly referred to a psychologist. Furthermore, the referral represents an almost exclusive form of collaboration present in the opinions of GPs. Only 8% of GPs would consider the joint and integrated work of the psychologist and doctor useful within the primary health care setting. This vision of the role of psychologists among GPs represents a constraint in implementing a comprehensive primary health care approach, as advocated by the World Health Organization.

Abstract
OBJECTIVE The BDS checklist is a self-report measure to assess the most common somatic symptoms in functional somatic syndromes, based on the diagnostic concept of Bodily Distress Syndrome. The aim of the study was to examine the psychometric properties and validity of the BDS checklist in a psychosomatic sample and to investigate whether it is suitable to detect DSM-5 somatic symptom disorders (SSD). METHOD In a cross-sectional study, n = 368 patients from a psychosomatic outpatient clinic completed the BDS checklist and a semi-structured clinical interview on SSD. Item and scale characteristics and measures of reliability and validity were determined. RESULTS The BDS checklist showed good item characteristics and reliability (Cronbach α = 0.89). Factor analysis confirmed four symptom clusters (CFI = 0.95, TLI = 0.95, RMSEA = 0.091, 90% CI = 0.085-0.097). The BDS total score showed significant correlations with other measures of somatic symptom burden (r = 0.79, p < .001), health anxiety (r = 0.46, p < .001), depression (r = 0.45, p < .001), and general anxiety (r = 0.41, p < .001). Higher BDS checklist scores were associated with higher physical and mental health impairment and higher health care use. Diagnostic accuracy regarding somatic symptom disorder was moderate (AUC = 0.72, 95% CI: 0.67-0.77). CONCLUSION Findings of our study indicate that the BDS checklist is a reliable and valid measure to assess the most common somatic symptoms in a psychosomatic setting. It is however not sufficient to detect persons at risk for somatic symptom disorder. A combination with further questionnaires could probably improve diagnostic accuracy.

Abstract
When patients present with persistent bodily complaints that cannot be explained by a symptom-linked organic pathology (medically unexplained symptoms), they are diagnosed with 'functional' somatic syndromes (FSS). Despite their prevalence, the management of FSS is notoriously challenging in clinical practice. This may be because FSS are heterogeneous disorders in terms of etiopathogenesis. They include patients with primarily peripheral dysfunction, primarily centrally driven somatic symptoms, and a mix of both. Brain-imaging studies, particularly data-driven pattern recognition methods using machine learning algorithms, could provide brain-based biomarkers for these clinical conditions. In this review, we provide an overview of our brain imaging data on brain-body interactions in one of the most well-known FSS, irritable bowel syndrome (IBS), and discuss the possible development of a brain-based biomarker for FSS. Anticipation of unpredictable pain, which commonly elicits fear in FSS patients, induced increased activity in brain areas associated with hypervigilance during rectal distention and non-distention conditions in IBS. This was coupled with dysfunctional inhibitory influence of the medial prefrontal cortex (mPFC) and pregenual anterior cingulate cortex (pACC) on stress regulation systems, resulting in the activated autonomic nervous system (ANS) and neuroendocrine system stimulated by corticotropin-releasing hormone (CRH). IBS subjects with higher alexithymia, a risk factor for FSS, showed stronger activity in the insula during rectal distention but reduced subjective sensitivity. Reduced top-down regulation of the ANS and CRH system by mPFC and pACC, discordance between the insula response to stimulation and subjective sensation of pain, and stronger threat responses in hypervigilance-related areas may be a candidate brain-based biomarker.

Abstract
OBJECTIVE To assess the cost-effectiveness of a brief cognitive behavioural intervention for patients with medically unexplained physical symptoms (MUPS) provided by a mental health nurse practitioner (MHNP) in primary care in comparison with usual care. METHODS We performed an economic evaluation from a societal perspective alongside a cluster randomised controlled trial with 12 months follow-up. The primary outcome was quality-adjusted life-years (QALYs). Secondary outcomes were the RAND-36 physical component summary score (PCS), somatic symptom severity (Patient Health Questionnaire (PHQ-15), and anxiety and depression symptoms (Hospital Anxiety and Depression Scale (HADS)). Missing data were imputed using multiple imputation. We used non-parametric bootstrapping to estimate statistical uncertainty. The bootstrapped cost-effect pairs were used to estimate cost-effectiveness planes and cost-effectiveness acceptability curves. RESULTS Mean total costs in the intervention group were significantly lower than in the usual care group (mean difference - 2300€, 95% CI -3257 to -134). The mean difference in QALYs was 0.01 (95% CI -0.01 to 0.04), in PCS 2.46 (95% CI 1.44 to 3.47), in PHQ-15 -0.26 (95% CI -0.81 to 0.28), and in HADS -0.07 (-0.81 to 0.67). At a willingness to pay of 0 € per additional unit of effect, the probability of the intervention being cost-effective was 0.93 for QALYs and 0.92 for PCS, PHQ-15 and HADS scores. CONCLUSION Our intervention is cost-effective compared to usual care for patients with MUPS. Implementation of the intervention has the potential to result in a significant decline in costs. However, large scale implementation would require increased deployment of MHNPs.

Abstract
IMPORTANCE Somatic symptom and related disorders are highly prevalent mental health disorders among young people. Presentation can be varied, and patients often face long delays and see multiple practitioners to receive a diagnosis. OBJECTIVE To evaluate the health care use and costs in a population-based sample of children and young people with somatic symptom and related disorders in Ontario, Canada. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study used linked health and administrative databases in Ontario, Canada, where health services are funded through a universal single-payer health insurance plan. Participants included children aged 4 to 12 years, adolescents aged 13 to 17 years, and young adults aged 18 to 24 years residing in Ontario, Canada, during the period of April 1, 2008, to March 31, 2015. Included participants had a first health record diagnosis of somatic symptom and related disorders and were grouped based on the setting of their index somatic symptom and related disorders contact: outpatient, emergency department, or inpatient. Data were analyzed from August 1, 2017, to February 1, 2018. EXPOSURES One year before and 1 year after diagnosis of somatic symptom and related disorders. MAIN OUTCOMES AND MEASURES Outcome measures included overall and mental health-specific ambulatory and acute care visits and overall health system costs and sector-specific costs. RESULTS A total of 33 272 patients (median [interquartile range {IQR}] age, 20 [16-22] years; 17 387 female [52.3%]) were included in the analysis. Among these patients, 3875 (11.6%) were aged 4 to 12 years, 7273 (21.9%) were aged 13 to 17 years, and 22 124 (66.5%) were aged 18 to 24 years. A total of 17 893 (53.8%) had their index visit as outpatients, whereas 13 310 (40.0%) and 2069 (6.2%) were diagnosed in the emergency department and inpatient settings, respectively. Ambulatory physician visits were frequent and persisted 1 year after diagnosis within each setting (before vs after 1 year, median [IQR] visits, inpatient setting: 7 [3-13] vs 7 [3-13]; emergency department setting: 4 [2-8] vs 4 [2-9]; outpatient setting: 3 [1-7] vs 4 [2-7]; P < .001). After diagnosis, many did not receive physician-delivered mental health care (35.3% [730 of 2069] in an inpatient setting, 59.1% [7866 of 13 310] in an emergency department setting, 58.5% [10 467 of 17 893] in an outpatient setting; P < .001). Acute care use was frequent and remained so after diagnosis across settings. Of those hospitalized as inpatients at diagnosis, 37.7% (779 of 2069) were readmitted within 1 year. Mean (SD) 2-year patient costs were CAD$9845 ($39 725) (median [IQR], $2401 [$960-$7019]). Hospitalized patients had a 2-year mean (SD) cost of $51 424 ($100 416) (median [IQR], $21 997 [$12 510-$45 841]) per-patient expenditure. CONCLUSION AND RELEVANCE This study found that children and young people with somatic symptom and related disorders frequently used the health system with substantial health system costs before and after diagnosis. Many of these patients did not receive physician-delivered mental health care. These findings suggest that this population may be under-recognized, and initiatives for early recognition and engagement with mental health support may be warranted.

Abstract
Understanding the mechanisms of symptoms that are insufficiently explained by organic dysfunction remains challenging. Recently, it has been proposed that such "functional symptoms" are based on erroneous sensory processing in the central nervous system (CNS), with internal expectations dominating sensory inputs. In a pilot study, we used a head motor control set-up to assess the interplay between sensory input and expectation on the example of patients with functional dizziness. Eight patients and 11 age-matched healthy controls performed large active eye-head gaze shifts towards visual targets in the natural situation and with the head moment of inertia 3.3-fold increased. The latter induces head oscillations and the expected sensory outcome of the movement, estimated in the CNS, does not match the actual sensory input. Head oscillations were assessed in patients and in healthy subjects and compared to prior results from patients with organic disease (vestibular loss and cerebellar ataxia). Head oscillations in patients with functional dizziness were different from those of healthy subjects (F(1,17)=27.26, P<0.001, partial η2=0.62), and similar to those of patients with cerebellar ataxia, and with vestibular loss (F(2,19)=0.56, P=0.58). Even in the natural, unweighted, condition, head oscillations were higher in functional dizziness patients than in healthy subjects (P=0.001). Since an extensive work-up failed to demonstrate any explanatory peripheral vestibular, motor, or cerebellar organic dysfunction, these motor control deficits are a first indication of erroneous interplay between expectations and sensory input in the CNS that could account for persistent physical symptoms.
