Self-reports after whiplash often indicate associations with vertigo and reading problems. Neuropsychological and otoneurological tests were applied to a group of whiplash patients (n = 26) and to a carefully matched control group. The whiplash group deviated from the control group on measures of eye movements during reading, on smooth pursuit eye movements with the head in normal position, and with the body turned to the left or to the right. Clinical, caloric, and neurophysiological tests showed no injury to the vestibular system or to the CNS. Test results suggest that injuries to the neck due to whiplash can cause distortion of the posture control system as a result of disorganized neck proprioceptive activity.
Even though the gentamicin-treated patients had less vertigo, no difference in overall quality of life was found between the surgically treated and untreated patients. The sense of coherence seems to be an important factor in the patient's experience of quality of life. Quality of life instruments can measure both specific symptoms and related aspects on quality of life and may give complementary information to the AAO/HNS classification in evaluating the treatment of patients with Ménière's disease.
Past studies examining whether or not cognitive changes actually have occurred as a result of a whiplash (WL) accident have produced varying results. The aim of this study was to identify possible cognitive dysfunctions in a group with persistent problems after whiplash due to injuries to the posture control system and related structures. The whiplash subjects (n = 23) were selected on the basis of their reduced gain in the Smooth Pursuit Neck Torsion test (SPNT). The WL group differed significantly from a closely matched control group on tests of learning and memory, and prolonged divided attention and concentration. After attempting to rule out other ways of interpreting these differences (such as pain, depression, medication, and premorbid health problems), these data were interpreted as lending support to the notion of a causal connection between the disturbed posture control system and some cognitive malfunctions.
(A) Any disorder of the central nervous system (CNS), (B) migraine, (C) active Ménière's disease, and (D) severe eye disorders. Symptom questionnaire ('yes or no' answers during a personal interview) and Dizziness Handicap Inventory (DHI) were used. Results We included 69 patients (20 males and 49 females) with a median age of 45 years (range 21-68 years). The median duration of the disease was five years and three months. The video-oculography confirmed BPPV in more than one semicircular canal in all patients. In 15% there was a latency of more than 1 min before nystagmus occurred. The Dizziness Handicap Inventory (DHI) median score was 55.5 (score >60 indicates a risk of fall). Seventy-five percent were on 50-100% sick leave. Eighty-one percent had a history of head or neck trauma. Nineteen percent could not recall any history of trauma. In our cohort, nautical vertigo and dizziness (81%) was far more common than rotatory vertigo (20%). The majority of patients (87%) reported pain as a major symptom: neck pain (87%), headache (75%) and widespread pain (40%). Fatigue (85%), visual disturbances (84%), and decreased concentration ability (81%) were the most frequently reported symptoms. In addition, unexpected findings such as involuntary movements of the extremities, face, neck or torso were found during otolith repositioning maneuvers (12%). We describe one case, as an example, how treatment of his BPPV also resolved his chronic, severe pain condition. Conclusion This observational study demonstrates a likely connection between chronic BPPV and the following symptoms: nautical vertigo/dizziness, neck pain, headache, widespread pain, fatigue, visual disturbances, cognitive dysfunctions, nausea, and tinnitus. Implications Patients with complex pain conditions associated with nautical vertigo and dizziness should be evaluated with the Dizziness Handicap Inventory (DHI)-questionnaire which can identify treatable balance disorders in patients with chronic musculoskeletal pain.
Background: In patients with chronic benign paroxysmal positional vertigo (BPPV), i.e., chronic vestibular multicanalicular canalithiasis (CVMCC), abnormal signals are transmitted from diseased labyrinths via the healthy vestibular nuclei complex to their end organs. The vestibulo-thalamo-cortical reflex as proposed in vestibular migraine is just one of these reflexes. In a group of patients diagnosed with CVMCC otolith repositioning maneuvers specific for each semicircular canal (SCC) ameliorated pain and other symptoms in 90%. Increased awareness of CVMCC may reduce suffering and continuous medication. Objective: To evaluate if CVMCC can be the trigger of symptoms in vestibular migraine, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and whiplash associated disorders (WAD). Study Design: Retrospective consecutive observational cohort study. Setting: Ambulatory at a private Otoneurology Centre. Patients: One hundred sixty-three patients with CVMCC and a history of trauma. Intervention: Based on the symptoms (structured symptom questionnaire), the patients are post hoc sub grouped according to the criteria of the different diagnoses. Main Outcome Measure: Frequency of patients with CVMCC who fulfill the criteria of the different diagnoses. Results: 98% of all patients with CVMCC fulfill the Barany Society criteria of a probable vestibular migraine; 17% fulfill the International Classification of Headache Disorders defined vestibular migraine criteria; 63% fulfill the Fukuda criteria of ME/CFS; 100% of the patients with WAD suffer from CVMCC. Conclusion: This survey supports the hypothesis that CVMCC can be the trigger of symptoms in vestibular migraine, ME/CFS, and WAD. The actual diagnosis the patient receives is often in accordance with the patient's dominant symptom.
This was a consecutive, prospective clinical study on 153 ambulatory patients in a tertiary referral center (i.e., a county hospital). All patients had whiplash-associated disorders (WAD) of at least grade II, according to the Quebec classification. All patients underwent pure-tone audiometry, and their audiograms were compared with ISO standards. Fourteen percent of patients with WAD had a hearing impairment exceeding the 90th percentile of the ISO standards. However, in most cases the hearing was not associated with whiplash injury. A subgroup (33 patients)--with normal hearing or slight hearing impairment according to the audiogram--was selected from the total group of patients with WAD. The 33 selected patients and 33 matched controls were tested with the speech-in-noise test (SRN test). However, 40% of this subgroup of patients with WAD reported hearing problems. As many as 30% of the patients with WAD had an abnormal SRN test result, as against 5% of the controls. Significant relations were found between the SRN test and self-assessed hearing loss, but not between the SRN test and tinnitus.
Background and aim Chronic musculoskeletal pain, e.g. whiplash associated disorders (WAD), fibromyalgia and myalgia, causes significant burden on both the individual and on society as a whole. In a previous study, the authors concluded that there is a likely connection between chronic benign paroxysmal positional vertigo (BPPV)/canalithiasis and headache, neck pain, generalized pain, fatigue, cognitive dysfunctions as well as tinnitus. The balance dysfunction in BPPV/canalithiasis is dynamic and not static. This leads to a perpetual postural mismatch. The vicious cycle of a disturbed equilibrium control system may be the driving force behind the vicious cycle of pain. The aim of this study is to investigate if otolith-repositioning manoeuvres in patients with chronic BPPV/canalithiasis can be beneficial. Methods During a period of about two years a prospective observational study on patients with chronic musculoskeletal pain referred for physiotherapy was performed. Those with a Dizziness Handicap Inventory (DHI) inquiry score above 20 underwent further investigations to diagnose chronic BPPV/canalithiasis. Diagnostic criteria: (A) The diagnosis of BPPV/canalithiasis was confirmed with the following: (1) specific history of vertigo or dizziness provoked by acceleration/deceleration, AND (2) nystagmus and symptoms during at least one of the test positions; (B) the disorder had persisted for at least one year. Specific otolith repositioning manoeuvre for each semi-circular canal (SCC) was performed. Symptom questionnaire ("yes" or "no" answers during a personal interview) and a follow-up questionnaire were used. Results The responders of the follow-up questionnaire constituted the study group. Thirty-nine patients responded (i.e. 87%) (31 females, 8 males) with a median age of 44 years (17-65). The median duration of the disease was5 years. Seventy-nine percent had ahistory ofhead or neck trauma. The DHI median score was 48 points (score >60 indicates a risk of fall). The video-oculography confirmed BPPV/canalithiasis in more than one semi-circular canal in all patients. In the present study the frequency of affected anterior semi-circular canal (SSC) was at a minimum of 26% and could be as high as 65%. Ninety-five percent suffered from headache, 92% from neck pain, 54% had generalized pain, and 56% had temporo-mandibular joint region pain. Fatigue (97%), aggravation by physical exertion (87%), decreased ability to concentrate (85%) aswellas visual disturbances (85%) were the most frequently reported symptoms, and 49% suffered from tinnitus. The median number of otolith repositioning manoeuvres done was six (2-29). Median time span between finishing otolith repositioning manoeuvres and answering the questionnaire was 7 months. Effects of treatment and conclusion The present study has shown that repositioning of otoliths in the SCCs in nearly all patients with chronic BPPV/canalithiasis ameliorated pain and other symptoms. The correlation between vertigo/dizziness and the majority of symptoms was significant. Theref...
