Soccer and Benign Paroxysmal Positional Vertigo. Case Rep Otolaryngol 2023; 2023:3744863. [PMID: 36824702 PMCID: PMC9943621 DOI: 10.1155/2023/3744863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 01/08/2023] [Accepted: 01/16/2023] [Indexed: 02/16/2023] Open
Abstract
Introduction. Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo among adults. The etiology of BPPV is unknown in approximately 50 percent of cases. This condition is also termed primary BPPV, if the etiology is unknown, and secondary BPPV if patients have identified predisposing factors. A few studies suggest that there is a correlation between the development of BPPV and specific sports. Case Report. A 19-year-old male presented with recurrent episodes of vertigo during soccer play. Eight months prior to referral, the patient was involved in a car accident with a mild head trauma. The patient was later diagnosed with BPPV several times. Discussion. Soccer might be a plausible BPPV trigger, especially if there is a prehistory of head trauma. This is most likely due to the demands of the game such as the change of directions, repetitive head impacts (headers or head collisions), accelerations/decelerations, jumps, foot landings, and rapid head movements.

Physiological Demands and Muscle Activity of “Track-Work” Riding in Apprentice Jockeys. Int J Sports Physiol Perform 2022; 17:1698-1705. [DOI: 10.1123/ijspp.2022-0160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 07/17/2022] [Accepted: 08/24/2022] [Indexed: 11/09/2022]
Abstract
Purpose: To enhance performance in race riding, knowledge of current training workload is required. The objectives of this study were to quantify the physiological demands and profile the muscle activity of jockeys riding track-work. Methods: Ten apprentice jockeys and 48 horses were instrumented with heart-rate monitors, accelerometers, and a surface electromyography BodySuit (recording 8 muscle groups: quadriceps, hamstrings, gluteal, lower back, obliques, abdominal, trapezial, and pectoral) that recorded continuously while riding their normal morning track-work. Data were extracted and time matched into 200-m sections for analysis once the jockey reached steady-state canter (6.9 m·s−1). Results: Jockeys rode a mean (±SD) of 6 (1) horses each morning over 2.5 hours, spending ∼30 minutes at a canter (8.8 [ 0.7] m·s−1), with mean heart rate of 129 (11) beats·min–1 and ratings of perceived exertion representing easy-/moderate-intensity exercise. Mean magnitude of horse (0.17 [0.01] m) and jockey center of mass (0.16 [0.02] m) displacement per stride differed from that of the jockey’s head (0.11 [0.01] m, P < .05). The majority of horse oscillation was damped in the upper body with a 3-fold reduction in the medio/lateral and fore/aft planes (P < .05), to minimize jockey head movement. Lower-body muscles absorbed horse motion, with core and upper-body muscles important for postural stabilization. Conclusions: The physiological demands of riding track-work were low, with no evidence of fatigue. Future research on jockeys in races as comparison would identify the specific requirements of a jockey-specific physical conditioning program.

Abstract
Vibrations experienced by cyclists can affect their performance and health. We analysed the vibrations transmitted by mountain bike (26 or 29-inch wheels), in a 2,110 m circuit with a sample of 55 cyclists. The results indicate that the 29"-wheel increases speed (p < 0.001) and thus performance but it also increases exposure to vibrations as the root mean square (RMS) indicate (p = 0.001). The wheel diameter significantly affected the accelerometer-related dependent variables (p < 0.01), specifically seen in the RMS variable (p < 0.01). Regarding vibration transmission variables, it was found that the LW/FH, RW/FH, LA/RH, and RA/RH ratios were higher in the 29" bicycle than in 26" one. Average heart rate (p = 0.01) and maximum heart rate (p < 0.01) values were higher for the 29" bike with no significant differences in the average power values recorded. In conclusion, bicycles with 29" wheels transmit higher levels of vibration to riders.

Abstract
Background and Purpose: The lifetime prevalence of benign paroxysmal positional vertigo (BPPV) is high, especially in the elderly. Patients with BPPV are more susceptible to ischemic stroke, dementia, and fractures, severely reducing quality of life of patients. Many studies have analyzed risk factors for the occurrence of BPPV. However, the results of these studies are not identical. We performed this meta-analysis to determine potential risk factors associated with the occurrence of BPPV. Methods: PubMed, EMBASE, and the Cochrane Library (January 2000 through March 2020) were systematically searched for eligible studies analyzing risk factors for the occurrence of BPPV. Reference lists of eligible studies were also reviewed. We selected observational studies in English with a control group and sufficient data. Pooled odds ratios (ORs) or the mean differences (MDs) and 95% confidence intervals (CIs) were calculated to measure the impacts of all potential risk factors. Heterogeneity among studies was evaluated using the Q-test and I2 statistics. We used the random-effect model or the fixed-effect model according to the heterogeneity among the included studies. Results: We eventually included 19 studies published between 2006 and 2019, including 2,618 patients with BPPV and 11,668 participants without BPPV in total. In this meta-analysis, the occurrence of BPPV was significantly associated with female gender (OR = 1.18; 95% CI, 1.05–1.32; P = 0.004), serum vitamin D level (MD = −2.12; 95% CI, −3.85 to −0.38; P = 0.02), osteoporosis (OR = 2.49; 95% CI, 1.39–4.46; P = 0.002), migraine (OR = 4.40; 95% CI, 2.67–7.25; P < 0.00001), head trauma (OR = 3.42; 95% CI, 1.21–9.70; P = 0.02), and total cholesterol level (MD = 0.32; 95% CI, 0.02–0.62; P = 0.03). Conclusion: Female gender, vitamin D deficiency, osteoporosis, migraine, head trauma, and high TC level were risk factors for the occurrence of BPPV. However, the effects of other risk factors on BPPV occurrence need further investigations.

Abstract
OBJECTIVES The aim of this investigation was to evaluate the association between posterior channel benign paroxysmal positional vertigo (BPPV) and trauma that is frequently experienced by American football players. MATERIALS AND METHODS Participants were classified into the following two groups: (1) a study group consisting of 63 male participants aged 18-30 years who had been playing American football for more than 2 years and (2) a control group consisting of 49 male participants aged 18-27 years with no history of otologic/vestibular disease or acute/chronic trauma. Trauma, age, total duration of playing American football, and weekly training hours of subjects in the study group were analyzed to determine any relationship with BPPV occurrence. We performed otologic, audiologic, and vestibular assessments of pure sound audiometry, tympanometry, tandem walking test with eyes open and eyes closed, Romberg, head shaking, roll, and Dix-Hallpike tests to all participants. RESULTS A positive correlation between the total years of American football played and posterior channel BPPV frequency was observed in the study group. In addition, increasing weekly hours of training was shown to further increase the risk of BPPV. A total of 16 out of 63 athletes experienced BPPV, whereas none of the participants in the control group experienced BPPV. All participants completed the Vertigo Symptom Scale, which revealed that vertigo did not cause any significant negative impact on their training routine and activities of daily living. CONCLUSION Our results indicate that the weekly training hours and total years of training with American football increase posterior channel BPPV frequency.

Abstract
Objective To investigate whether mechanical vibrational energy from using an electric toothbrush may cause an increase in the incidence of benign paroxysmal positional vertigo (BPPV) and prevent successful treatment of BPPV with canalith repositioning procedure. Methods This was a retrospective study conducted at an otolaryngology private practice. A survey of 111 patients who were diagnosed with BPPV in an otolaryngology practice between May 2012 and January 2017 was conducted using a questionnaire that included questions regarding demographics, inner ear pathology, treatment method, and use of an electric toothbrush. The results were recorded and compared using a chi-square test of analysis or Fisher's exact test. Results Overall, 47 (42.3%) of the 111 BPPV patients used an electric toothbrush, whereas 64 of the 111 (57.6%) patients did not. Six (12.7%) of the 47 patients experienced dizziness with electric toothbrush use. Of the 47 patients using an electric toothbrush, 33 (70.2%) had a resolution of symptoms after Epley treatment, whereas 14 (23.4%) of 47 patients did not. Of the 64 patients who did not use an electric toothbrush, 15 (23.4%) did not have resolution after Epley treatment. Of the 47 patients using an electric toothbrush, 6 (12.8%) had a recurrence of BPPV diagnosed in the office, whereas 41 (82.2%) did not. Seven (10.9%) of those who did not use an electric toothbrush had a recurrence of BPPV, whereas 57 (89.1%) of the 64 patients did not. These results were not statistically significant (p = 0.77). Conclusions This study suggests that the mechanical vibrations from electric toothbrush use do not have an association with recurrent BPPV. The results align with some publications demonstrating that vibrations in the head and neck area from the use of an electric toothbrush can initiate dizziness; however, it does not appear that this modality of vibration is significant for inducing recurrent BPPV.

Abstract
OBJECTIVE To explore the aetiology of and to evaluate the importance of MRI investigation on the posterior semicircular canal benign paroxysmal positional vertigo in an Irish population. METHODS A retrospective observational study of 500 patients with posterior semicircular canal benign paroxysmal positional vertigo, diagnosed and treated by the senior author over a 10-year period. Most patients underwent an MRI brain and inner ear, following the same scan protocol. This included T1 weighted sagittal IR-FSPGR volume, axial T2 weighted, gradient echo T2 weighted and FLAIR sequences plus time of flight cerebral angiography. RESULTS The average age of presentation was 56 years; with the overall female to male ratio was 1.6:1, which was largely the net results of 2 age groups. Over 30% of our patients recalled distinct aetiological triggers, of which the top 3 were trauma, infection, and surgery. These accounted for 16%, 6%, and 5%, respectively. More than 25% of the patients were discovered to have abnormal intracranial findings on MRI. The 2 most common non-infarct incidental findings were neoplasia and vascular abnormalities. Although fewer than 20 patients had acute intracranial haemorrhage or malignant tumours, most of them were urgently referred to neurosurgeon due to the life-threatening nature of the condition. One round of particle repositioning manoeuver was successful in treating 84% of the patients, and the 2-year recurrence rate was only 2.2%. CONCLUSION The diagnosis of posterior semicircular canal benign paroxysmal positional vertigo is thought to be relatively easy to make, and the treatment is highly effective. Clinicians should be fully aware of and prepared for the diverse aetiology, and thus have no hesitation in requesting MRI scan as an important investigation.

Abstract
OBJECTIVE To test the hypothesis that levels of a BPPV biomarker, otolin-1, correlate with those of osteoporosis markers, aminoterminal propeptide of protocollagen type I (P1NP), and aminoterminal telopeptides of collagen (NTX), thus further supporting a link between the two diseases. STUDY DESIGN Prospective pilot clinical trial (Level of Evidence: 2b). PATIENTS Postmenopausal women with BPPV. INTERVENTIONS Diagnostic. MAIN OUTCOME MEASURES Serum levels of otolin-1, P1NP, NTX, vitamin D, and calcium were examined in relation to each other, age, and DEXA scan T-scores. RESULTS There was a strong, negative correlation between T-scores and otolin-1 levels. Although P1NP and NTX levels were strongly correlated, neither had statistical correlations with otolin-1. CONCLUSIONS Despite a strong correlation between DEXA scan results and otolin-1 levels, there were no significant correlations between otolin-1 and P1NP or NTX. This suggests that the association between osteoporosis and BPPV is complex, but not likely to be causal. Although more work is needed to elucidate these relationships, this preliminary finding has important practical implications for BPPV in that proactive management of osteoporosis, per se, would not be expected to have benefits in management of BPPV.

Abstract
Background Benign paroxysmal positional vertigo (BPPV), the most common type of vertigo in the general population, is thought to be caused by dislodgement of otoliths from otolithic organs into the semicircular canals. In most cases, however, the cause behind the otolith dislodgement is unknown. Dental procedures, one of the most common medical treatments, are considered to be a possible cause of BPPV, although this has yet to be proven. This study is the first nationwide population-based case-control study conducted to investigate the correlation between BPPV and dental manipulation. Methods Patients diagnosed with BPPV between January 1, 2007 and December 31, 2012 were recruited from the National Health Insurance Research Database in Taiwan. We further identified those who had undergone dental procedures within 1 month and within 3 months before the first diagnosis date of BPPV. We also identified the comorbidities of the patients with BPPV, including head trauma, osteoporosis, migraine, hypertension, diabetes, hyperlipidemia and stroke. These variables were then compared to those in age- and gender-matched controls. Results In total, 768 patients with BPPV and 1536 age- and gender-matched controls were recruited. In the BPPV group, 9.2% of the patients had undergone dental procedures within 1 month before the diagnosis of BPPV. In contrast, only 5.5% of the controls had undergone dental treatment within 1 month before the date at which they were identified (P = 0.001). After adjustments for demographic factors and comorbidities, recent exposure to dental procedures was positively associated with BPPV (adjusted odds ratio 1.77; 95% confidence interval 1.27–2.47). This association was still significant if we expanded the time period from 1 month to 3 months (adjusted odds ratio 1.77; 95% confidence interval 1.39–2.26). Conclusions Our results demonstrated a correlation between dental procedures and BPPV. The specialists who treat patients with BPPV should consider dental procedures to be a risk factor, and dentists should recognize BPPV as a possible complication of dental treatment.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular problem. However, demographic analysis is few. AIM The aim of this study was to document the demographic data of patients with BPPV regarding distribution of gender, age, associated problems, most common form, symptom duration, severity of nystagmus and cure rate. SUBJECTS AND METHODS A total of 263 patients with video-nystagmography confirmed BPPV were enrolled in this retrospective study (2009-2013). The data were collected in Anadolu Medical Center. Distribution of gender, age and affected side were reviewed. Associated problems were noted. Patients were analyzed according to the canal involvement, age, duration of symptoms, duration of nystagmus and recurrence. Mean values and standard deviations were calculated. One-way ANOVA test was used for the analysis of the data (Statistical Package for the Social Sciences 17.0 version, IBM, Chicago, III, USA). Statistical significance was set at P < 0.05. RESULTS Women were affected more frequently than men (1:1.5). Comparative analysis of average age between the two gender groups was not statistically significant (P = 0.84). BPPV was common at middle age group. The incidence of affected side was not significant (P = 0.74). Posterior canal-BPPV (PC-BPPV) was the most leading one (129/263; 49%) followed by lateral canal (LC)-canalolithiasis (60/263; 22.8%), LC-cupulolithiasis (38/263; 14.5%) and superior canal-BPPV (9/263; 3.4%). 55.1% of patients were defined as idiopathic (145/263). Associated problems were migraine (31/263; 11.8%), trauma (19/263; 7.2%), inner ear disorders (18/263; 6.8%) and other systemic problems (50/263; 19.1%). 72.6% of patients had symptoms <2 months (191/263). 23,6% of patients had intensive nystagmus lasting more than a minute regardless of canal involvement (62/263). 33% of patients required two or more maneuvers for the relief of symptoms (87/263). CONCLUSION Symptoms are prone to recur in those of traumatic origin, associated inner ear problems and systemic disorders. As the prognostic factors are illuminated, preventive measures will be more effective and more patients will be cured properly.

Abstract
Vertigo has been described after the practice of mountain bike. This study aimed to investigate the prevalence of vertigo following competitions or training sessions of downhill mountain biking (DMB) or road cycling (RC). One hundred and two DMB riders, 79 road cyclists and 73 control participants filled in a survey intended to evaluate the prevalence of vertigo in daily living activities and following competitions or training sessions. Vertigo causal factors (crashes, head trauma, fatigue, characteristics of the path/road ridden) were recorded. DMB riders and road cyclists did not report more vertigo during daily living activities than controls. But DMB riders older than 30 had more risk to report vertigo than age-matched road cyclists (OR: 5.06, 95% CI: 1.23-20.62). Road cyclists aged between 20 and 29 were 2.59-fold (95% CI: 1.06-6.27) more likely to report vertigo than controls. After competitions and training sessions, DMB riders were 2.33-fold (95% CI: 1.22-4.41) more likely to report vertigo than road cyclists. Vertigo causal factors were crash with head trauma in DMB riders and fatigue in road cyclists. Vertigo during daily living activities may be of concern for cyclists, particularly older DMB riders. The accumulation of impacts (crashes, vibrations) during the career of a DMB rider may generate micro-traumatisms of the central nervous system and/or peripheral vestibular structures, particularly the otolith organs. In RC, the pathophysiological mechanisms generating vertigo might be effort-related disturbance of homeostasis. To avoid injuries, DMB riders should be aware that vertigo may occur at the end of training sessions or competitions.

Abstract
Benign paroxysmal positional vertigo (BPPV), the most common cause of dizziness, occurs in all age groups. It presents with vertigo on head movement, but in older patients presentation may be typical and thus accounting for a low recognition rate in the primary care setting. It may be recurrent in up to 50% of cases. BPPV is associated with displacement of fragments of utricular otoconia into the semicircular canals, most commonly the posterior semicircular canal. Otoconia are composed of otoconin and otolin forming the organic matrix on which calcium carbonate mineralizes. Otoconia may fragment with trauma, age, or changes in the physiology of endolymph (e.g., pH and calcium concentration). Presentation varied because otoconia fragments can be displaced into any of the semicircular canals on either (or both) side and may be free floating (canalolithiasis) or attached to the cupula (cupulolithiasis). Most cases of BPPV are idiopathic, but head trauma, otologic disorders, and systemic disease appear to be contributory in a subset. Positional maneuvers are used to diagnose and treat the majority of cases. In rare intractable cases surgical management may be considered. A strong association with osteoporosis suggests that idiopathic BPPV may have diagnostic and management implications beyond that of a purely otologic condition.

Abstract
CONCLUSION Despite limitations arising from a questionnaire-performed study, it seems that nonspecific physical activity can protect against benign paroxysmal positional vertigo (BPPV), possibly by relocating loosened otoconia from the semicircular canals. OBJECTIVES Mechanical factors might play a role in the onset of the idiopathic form of BPPV. We performed a structured questionnaire study of physical activity in patients with BPPV and controls. METHODS Sixty-three consecutive patients with idiopathic BPPV participated in the study. Their mean age was 59.2 ± 14.5 years; 14 were men and 49 were women. Sixty-four age- and sex-matched generally healthy individuals served as controls. Levels of physical activity were assessed by the PASE questionnaire, which consists of 12 items quantifying physical activity during leisure, household, and occupational activities over a 7-day period. RESULTS The total physical score activity was significantly lower in BPPV patients than in controls. Differences were found mainly in household and leisure activity, while occupational activity was similar in both groups, regardless of gender. Patients older than 60 years had significantly lower PASE scores than controls, whereas patients aged 60 years or younger reported similar physical activity to controls. No differences were found between physical activity scores in different types of BPPV or in patients with a first versus recurrent attack of vertigo.

Benign paroxysmal positional vertigo after intense physical activity: a report of nine cases. Eur Arch Otorhinolaryngol 2009; 266:1831-5. [PMID: 19288124 DOI: 10.1007/s00405-009-0938-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2008] [Accepted: 02/19/2009] [Indexed: 10/21/2022]
Abstract
The aim of this study was to report some clinical cases suggesting a possible correlation between benign paroxysmal positional vertigo (BPPV) and intense physical activity. Out of 430 BPPV cases referred to our out-patients clinic, 9 patients, showing symptoms of BPPV arising after an intense period of physical activity, were selected for this study. The posterior semicircular canal was affected in all the nine patients. The canalith repositioning procedure was successful and eliminated vertigo and nystagmus in all patients. During the follow-up period (12 months) all patients continued with the usual physical activity; four of the nine patients showed a recurrence of the BPPV symptoms after a new intense period of exercises: all were successfully treated by a new single Epley repositioning procedure. BPPV due to intense physical activity is a rare condition (9/430) and it may be caused by repeated vibratory vertical accelerations of a minor degree associated with metabolic variations during strenuous exercise.
