Is Biofeedback for Vertigo Effective in Ordinary Medical Centers? A Controlled Trial in Northern Italy.

The aim of this study was to assess the therapeutic effectiveness of biofeedback, in a medical center's routine for treating vestibular disorders, reducing emotional, functional, and physical disability at three-month follow-up. A total of 197 outpatients were recruited from a medical center to treat vestibular disorders. Patients in the control group received treatment as usual, consisting of one monthly visit with an otolaryngologist and pharmacological treatment specific for vertigo, while the experimental group attended biofeedback training. Patients in the experimental group received pharmacological therapy only in the phase before the start of biofeedback in order to stabilize the acute phase. During the three-month follow-up, the experimental group did not receive any booster sessions of biofeedback. At three-month follow-up there was a statistically significant difference between the groups, both in the mean total score of the dizziness handicap inventory and in the three subscales: physical, emotional, and functional. Moreover, the biofeedback group had reduced psycho-physiological parameters for all average values at three-month follow-up compared to the baseline. This is one of few studies assessing the effectiveness of biofeedback in a naturalistic setting for vestibular disorder treatment. The data confirmed that biofeedback can impact illness course, in terms of self-perceived disability reduction, assessed on emotional, functional, and physical aspects of daily living.

Persistent-postural perceptual dizziness (PPPD): Yes, it is a psychosomatic condition!

The Barany society published recently the consensus document for the diagnostic criteria of persistent postural perceptual dizziness (PPPD). In this commentary we highlight the benefits of this new diagnosis and possible problems that can arise during the use of the criteria in day to day clinical practice at a University Clinic for Psychosomatic Medicine. The diagnostic criteria of PPPD are compared to those of somatic symptom disorder and bodily distress disorder. We think that a discussion from a psychosomatic point of view is important to improve the understanding between different specialties and how PPPD fits into the broader framework of psychosomatic medicine.

Efficacy of Yokukansan, a traditional Japanese herbal medicine, in patients with dizziness and irritability.

OBJECTIVE: Irritability is an emotional stress symptom that causes or exacerbates dizziness. Antidepressants may be helpful for some conditions that are accompanied by irritability; however, they do not completely inhibit irritability. Yokukansan (YKS), a traditional Japanese herbal medicine, has been used for neurosis, insomnia, and children's irritability and night crying. The study investigated the efficacy of YKS in nystagmus in patients with chronic dizziness and irritability. METHODS: Twenty-two cases with chronic dizziness and irritability were reviewed retrospectively. The patients were divided into two groups: control patients (0-7 days of treatment) and YKS-treated patients (YKS cases; >7 days of treatment). Dizziness before and during (after, in the controls) YKS treatment was evaluated by scoring the nystagmus intensity on a 5-point scale. The average scores were calculated within a maximum of 6 months before and during or after treatment. The normalized scores were also calculated. The optimal treatment regimen was calculated via receiver operating characteristic (ROC) curve analysis. RESULTS: There were six control cases (1 male, 5 females; mean age: 59.5 years). There were 16 YKS cases (3 males, 13 females; mean age: 61.8 years). While the group mean nystagmus intensity scores significantly decreased from 1.18 to 0.73 in the YKS cases, it did not change in the control cases. The group mean of the normalized nystagmus intensity scores during treatment was 0.73 in the YKS cases. The results of the ROC curve analysis indicated the optimal cut-off period of the YKS treatment was 10 days. CONCLUSION: The oral administration of YKS for more than 10 days was optimal. The treatments with YKS could be a good option for the treatments of vertigo.

[The influence of Memoplant monotherapy on the dizziness]. / Vliianie preparata Memoplant v rezhime monoterapii na golovokruzhenie.

The objective of the present work was to study the influence of the dry extract from the leaves of Ginkgo biloba EGb 761 (used as monotherapy at a dose of 120 mg twice daily during 4 months) on the vestibular function of the patients presenting with cochleovestibular pathology of peripheral and mixed genesis. We present the results obtained by the objective and subjective methods for the evaluation of the vestibular function as well as the neurological and psychoemotional state of the 40 patients that was carried out during the four months of memoplant monotherapy. It is concluded that monotherapy with the use of the dry extract from Ginkgo biloba leaves can be applied for the purpose of improvement of static and dynamic balancing state. Moreover, this memoplant preparation can be used as a means of prophylaxis of recurrent dizziness that in addition reduces the severity of anxiety and depression without producing adverse side effects.

Impact of fear of falling for patients and caregivers: perceptions before and after participation in vestibular and balance rehabilitation therapy.

PURPOSE: The purpose of this study was to investigate the impact of fear of falling (FoF) on older patients with dizziness history and their caregivers to better determine holistic needs when developing a patient-family centered approach to falling risk reduction. METHOD: A mixed-method design was used, incorporating a phenomenological qualitative approach to explore the impact of FoF in 14 patients and a family member or spouse of each patient. Quantitative analysis was used to further interpret results of interviews conducted before and after participation in a vestibular and balance rehabilitation program designed to reduce falling risk and improve balance confidence. RESULTS: Qualitative analysis of participant interviews pre and post vestibular rehabilitation revealed lifestyle changes for both participants and family caregivers due to FoF and the need for reducing falling concerns. Patient age showed statistically significant differences in levels of balance confidence, with younger participants (≤ 65 years) showing more concerns about the consequences of falling, even after rehabilitation, than older participants (> 65 years). CONCLUSION: The study highlights the impact of FoF on participation and activity levels of patients and family caregivers, as well as the need to thoroughly evaluate falling fears to achieve a holistic rehabilitation outcome.

Treating pediatric psychogenic dizziness with a Japanese herbal medicine.

OBJECTIVE: No conventional pharmacotherapy is available for the treatment of psychogenic dizziness in pediatric patients. Adults with psychogenic dizziness are treated with psychiatric medicines as the standard treatment. In children, this treatment is not widely accepted because of the potential for adverse reactions. Instead, Kampo, an alternative medicine, is probably the best choice of treatment. DESIGN: We report herein three of four cases of pediatric psychogenic dizziness successfully treated with Yoku-kan-san-ka-chimpi-hange (YKCH), a traditional Japanese Kampo medicine known to ameliorate psychiatric symptoms. SUBJECTS: YKCH was prescribed to four patients (two boys and two girls) with psychiatric dizziness whose ages ranged from 11 to 15 years. Four weeks after the initiation of treatment, clinical improvement was assessed by the Clinical Global impression-Improvement scale. RESULTS: In three of the four patients, the drug showed some significant effects. The remaining patient could not continue the medication. It is reasonable to assume that YKCH was effective because of its serotonergic mechanism and the improvement of sleep in our patients. CONCLUSIONS: This report is the first to describe the beneficial effects of YKCH in the treatment of pediatric psychogenic dizziness. We conclude that administration of YKCH may be a suitable complementary therapy for pediatric psychogenic dizziness.

Acoustic startle response in patients with orthostatic tremor.

BACKGROUND AND AIM: Orthostatic tremor is a high frequency tremor predominantly on calf muscles during standing. Brainstem is the most probable generator in the pathogenesis since it comprises bilaterally projecting centers regulating stance or tone. We aimed to investigate the functional role of brainstem through the evaluation of acoustic startle response in primary orthostatic tremor patients. PATIENTS AND METHOD: We included 7 (2 males) consecutive patients and 13 (5 males) healthy volunteers. Diagnosis was confirmed by polymyographic surface electromyography. All subjects underwent acoustic startle response and blink reflex investigations. RESULTS: Presence rate (71.4% vs. 100%, p=0.042) and response rate (27.5% vs. 40.5%, p=0.047) of total acoustic startle response were lower in patient group. Similarly, probability over orbicularis oculi was lower among patients (p=0.003). However, blink reflex was observed in all patients and healthy volunteers and latencies of startle and blink reflexes were similar between groups. CONCLUSIONS: In our patient group, normal response rate and latencies of R1 and R2 show structural integrity of at least blink reflex circuit at brainstem. On the other hand, suppressed response rates probably reflect decreased excitability of auditory startle reflex pathway.

Cognitions associated with anxiety in Ménière's disease.

OBJECTIVES: The purpose of this longitudinal study was to identify cognitions associated with anxiety and maintenance of anxiety in people with Ménière's disease. METHOD: At baseline, participants completed the Hospital Anxiety and Depression Scale (HADS), the Revised Illness Perception Questionnaire, the Dizziness Beliefs Scale, the Fear-Avoidance Beliefs Questionnaire, the Intolerance of Uncertainty Scale, and measures of demographic and illness characteristics. Participants were then randomized to a no-treatment group or to receive one of two self-help booklets, and completed the HADS again at 3-month follow-up. RESULTS: After symptom severity had been controlled for, baseline anxiety was found to be associated with intolerance of uncertainty, fear-avoidance of physical activity, belief that dizziness would develop into a severe attack of vertigo, and several illness perception subscales (emotional representations, consequences, psychological causes, and perceived treatment effectiveness). Anxiety on follow-up was predicted by higher baseline levels of autonomic/somatic symptoms and intolerance of uncertainty, and by reporting less understanding of the illness. These longitudinal relationships were found in those who did and who did not receive self-help booklets. CONCLUSIONS: Our findings suggest that intolerance of uncertainty is associated with anxiety in Ménière's disease. A controlled trial is needed to see whether anxiety might be reduced in Ménière's disease by helping patients tolerate and cope with uncertainty.

Evaluation of booklet-based self-management of symptoms in Ménière disease: a randomized controlled trial.

OBJECTIVE: This study examined the effectiveness of booklet-based education in vestibular rehabilitation (VR) and symptom control (SC) techniques to manage vertigo and dizziness in Ménière disease. METHODS: Participants (n = 360) were randomized to a waiting list control group or to receive either a VR or an SC self-management booklet. VR involved provoking dizziness in a controlled manner by making repeated head movements in order to promote neurological and psychological habituation. SC involved using applied relaxation, challenging negative beliefs, and lifestyle modification to reduce amplification of dizziness by anxiety. Subjective improvement in health, enablement (ability to understand and cope with symptoms), and adherence were measured at 3 and 6 months. Symptoms, handicap, anxiety and depression, and negative beliefs about symptoms were assessed pretreatment and at 3 and 6 months. RESULTS: At 6-month follow-up, 45 (37.5%) of the VR group and 47 (39.2%) of the SC group reported improvement compared with 19 (15.8%) controls; the relative probability of improvement compared with controls was 2.37 (95% confidence interval [CI], 1.48-3.80) for VR and 2.47 (95% CI, 1.55-3.95) for SC. Both intervention groups reported greater enablement than controls (p < .001, d > 0.70). At 3 months, the VR group had reduced symptoms, anxiety, handicap, and negative beliefs about dizziness; the SC group had reduced handicap; but the control group showed no improvement. Reported adherence levels were low and strongly related to outcome. CONCLUSIONS: Self-management booklets offer an inexpensive and easily disseminated means of helping people with Ménière disease to cope with dizziness symptoms.

Informing nurses of the lived experience of acupuncture treatment: a phenomenological account.

Acupuncture is a component of Traditional Chinese Medicine, focusing on a holistic, energy-based approach to the individual, rather than a disease-oriented, diagnostic, and treatment model. Nurses are increasingly involving themselves in the use of acupuncture as practitioners and as supporters of acupuncture in mainstream health care. This project described the lived experience of acupuncture treatment, with specific objectives to: inform nurses of people's experiences of having acupuncture; give nurses the language to explain to patients the experience of having acupuncture; and create possibilities for offering acupuncture as an informed choice of treatment in nursing and health care. The phenomenon of experiencing acupuncture was located within the participants' accounts of what it was like for them before, during, and after treatment.
