Comparison of Effects Produced by Physiological Versus Traditional Vocal Warm-up in Contemporary Commercial Music Singers
Source:Journal of Voice
Author(s): María Priscilla Portillo, Sandra Rojas, Marco Guzman, Camilo Quezada
PurposeThe present study aimed to observe whether physiological warm-up and traditional singing warm-up differently affect aerodynamic, electroglottographic, acoustic, and self-perceived parameters of voice in Contemporary Commercial Music singers.MethodsThirty subjects were asked to perform a 15-minute session of vocal warm-up. They were randomly assigned to one of two types of vocal warm-up: physiological (based on semi-occluded exercises) or traditional (singing warm-up based on open vowel [a:]). Aerodynamic, electroglottographic, acoustic, and self-perceived voice quality assessments were carried out before (pre) and after (post) warm-up.ResultsNo significant differences were found when comparing both types of vocal warm-up methods, either in subjective or in objective measures. Furthermore, the main positive effect observed in both groups when comparing pre and post conditions was a better self-reported quality of voice. Additionally, significant differences were observed for sound pressure level (decrease), glottal airflow (increase), and aerodynamic efficiency (decrease) in the traditional warm-up group.ConclusionBoth traditional and physiological warm-ups produce favorable voice sensations. Moreover, there are no evident differences in aerodynamic and electroglottographic variables when comparing both types of vocal warm-ups. Some changes after traditional warm-up (decreased intensity, increased airflow, and decreased aerodynamic efficiency) could imply an early stage of vocal fatigue.

Rotational and Collic Vestibular-Evoked Myogenic Potential Testing in Normal Developing Children and Children With Combined Attention Deficit/Hyperactivity Disorder.
Objectives: Vestibular dysfunction in childhood can have a major effect on a child's developmental process. Balance function has been reported to be poorer in children with attention deficit and hyperactivity disorder (ADHD) than in their typically developing peers. Due to contradictory available evidence and the paucity of research on vestibular function specifically in children with combined ADHD (cADHD), we designed this aged-matched study to assess vestibular function in children with cADHD. Design: We enrolled 30 typically developing children (15 boys and 15 girls; mean age, 9 years 6 months; range, 7 to 12 years) and 33 children (19 boys and 14 girls; mean age, 9 years 0 months; range, 7 to 12 years) with cADHD diagnosed by our research psychiatrist. Typically developing controls were used to obtain normative data on vestibular testing and to examine the impact of age on the vestibular response parameters, and these results were compared with those of the cADHD group. All children underwent the sinusoidal harmonic acceleration subtype of the rotary chair test (0.01, 0.02, 0.08, 0.16, and 0.32 Hz) and the cervical vestibular-evoked myogenic potential (cVEMP) test. Results: At all five frequencies in the sinusoidal harmonic acceleration test, there was no significant correlation between age and any of the following rotary chair response parameters in typically developing children: vestibulo-ocular reflex (VOR) gain, phase, asymmetry, and fixation index. Furthermore, there was no significant correlation between age and any of the following cVEMP parameters for the right and left ears of control group: p1 and n1 latency, amplitude, threshold, and amplitude ratio. Significantly higher VOR gains were observed for children with cADHD at frequencies of 0.01 (p = 0.001), 0.08 (p

Ankle-foot orthosis bending axis influences running mechanics
Publication date: July 2017

Author(s): Elizabeth Russell Esposito, Ellyn C. Ranz, Kelly A. Schmidtbauer, Richard R. Neptune, Jason M. Wilken
Passive-dynamic ankle-foot orthoses (AFOs) are commonly prescribed to improve locomotion for people with lower limb musculoskeletal weakness. The clinical prescription and design process are typically qualitative and based on observational assessment and experience. Prior work examining the effect of AFO design characteristics generally excludes higher impact activities such as running, providing clinicians and researchers limited information to guide the development of objective prescription guidelines. The proximal location of the bending axis may directly influence energy storage and return and resulting running mechanics. The purpose of this study was to determine if the location of an AFO's bending axis influences running mechanics. Marker and force data were recorded as 12 participants with lower extremity weakness ran overground while wearing a passive-dynamic AFO with posterior struts manufactured with central (middle) and off-centered (high and low) bending axes. Lower extremity joint angles, moments, powers, and ground reaction forces were calculated and compared between limbs and across bending axis conditions. Bending axis produced relatively small but significant changes. Ankle range of motion increased as the bending axis shifted distally (p<0.003). Peak ankle power absorption was greater in the low axis than high (p=0.013), and peak power generation was greater in the low condition than middle or high conditions (p<0.009). Half of the participants preferred the middle bending axis, four preferred low and two preferred high. Overall, if greater ankle range of motion is tolerated, a low bending axis provides power and propulsive benefits during running, although individual preference and physical ability should also be considered.

BackgroundDynamic and static varus alignment, both, have been reported as risk factors associated with structural progression of knee osteoarthritis. However the association of none of the static and dynamic alignment with structural, clinical, and functional progression associated with knee osteoarthritis has not been assessed yet in a longitudinal study.MethodsForty-seven women with early and established medial knee osteoarthritis were evaluated. Static and dynamic alignment as well as MRI detected structural features, clinical, and functional characteristics of patients were assessed at baseline and at 2 years follow-up. Associations between baseline static and dynamic alignment with structural, functional, and clinical characteristics at the time of entry, as well as the changes over 2 years were evaluated.FindingsBoth static and dynamic varus alignment at baseline were significantly associated with osteoarthritis related tibio-femoral joint structural abnormalities detected on MRI, at the time of entry. Only the magnitude of varus thrust at baseline was predictive of the changes in the presence of meniscal maceration over two years. None of the static or dynamic measures of knee joint alignment were associated with clinical characteristics associated with medial knee osteoarthritis.InterpretationThe key finding of this study is that both frontal plane dynamic and static alignment, are associated with structural abnormalities in patients with medial knee osteoarthritis.

Foot muscle morphology is related to center of pressure sway and control mechanisms during single-leg standing
Publication date: September 2017
Source:Gait & Posture, Volume 57
Author(s): Xianyi Zhang, Kurt Heinrich Schütte, Benedicte Vanwanseele
Maintaining balance is vitally important in everyday life. Investigating the effects of individual foot muscle morphology on balance may provide insights into neuromuscular balance control mechanisms. This study aimed to examine the correlation between the morphology of foot muscles and balance performance during single-leg standing. Twenty-eight recreational runners were recruited in this study. An ultrasound device was used to measure the thickness and cross-sectional area of three intrinsic foot muscles (abductor hallucis, flexor digitorum brevis and quadratus plantae) and peroneus muscles. Participants were required to perform 30s of single-leg standing for three trials on a force plate, which was used to record the center of pressure (COP). The standard deviation of the amplitude and ellipse area of the COP were calculated. In addition, stabilogram diffusion analysis (SDA) was performed on COP data. Pearson correlation coefficients were computed to examine the correlation between foot muscle morphology and traditional COP parameters as well as with SDA parameters. Our results showed that larger abductor hallucis correlated to smaller COP sway, while larger peroneus muscles correlated to larger COP sway during single-leg standing. Larger abductor hallucis also benefited open-loop dynamic stability, as well as supported a more efficient transfer from open-loop to closed loop control mechanisms. These results suggest that the morphology of foot muscles plays an important role in balance performance, and that strengthening the intrinsic foot muscles may be an effective way to improve balance.

BackgroundDynamic and static varus alignment, both, have been reported as risk factors associated with structural progression of knee osteoarthritis. However the association of none of the static and dynamic alignment with structural, clinical, and functional progression associated with knee osteoarthritis has not been assessed yet in a longitudinal study.MethodsForty-seven women with early and established medial knee osteoarthritis were evaluated. Static and dynamic alignment as well as MRI detected structural features, clinical, and functional characteristics of patients were assessed at baseline and at 2 years follow-up. Associations between baseline static and dynamic alignment with structural, functional, and clinical characteristics at the time of entry, as well as the changes over 2 years were evaluated.FindingsBoth static and dynamic varus alignment at baseline were significantly associated with osteoarthritis related tibio-femoral joint structural abnormalities detected on MRI, at the time of entry. Only the magnitude of varus thrust at baseline was predictive of the changes in the presence of meniscal maceration over two years. None of the static or dynamic measures of knee joint alignment were associated with clinical characteristics associated with medial knee osteoarthritis.InterpretationThe key finding of this study is that both frontal plane dynamic and static alignment, are associated with structural abnormalities in patients with medial knee osteoarthritis.

Maintaining balance is vitally important in everyday life. Investigating the effects of individual foot muscle morphology on balance may provide insights into neuromuscular balance control mechanisms. This study aimed to examine the correlation between the morphology of foot muscles and balance performance during single-leg standing. Twenty-eight recreational runners were recruited in this study. An ultrasound device was used to measure the thickness and cross-sectional area of three intrinsic foot muscles (abductor hallucis, flexor digitorum brevis and quadratus plantae) and peroneus muscles. Participants were required to perform 30s of single-leg standing for three trials on a force plate, which was used to record the center of pressure (COP). The standard deviation of the amplitude and ellipse area of the COP were calculated. In addition, stabilogram diffusion analysis (SDA) was performed on COP data. Pearson correlation coefficients were computed to examine the correlation between foot muscle morphology and traditional COP parameters as well as with SDA parameters. Our results showed that larger abductor hallucis correlated to smaller COP sway, while larger peroneus muscles correlated to larger COP sway during single-leg standing. Larger abductor hallucis also benefited open-loop dynamic stability, as well as supported a more efficient transfer from open-loop to closed loop control mechanisms. These results suggest that the morphology of foot muscles plays an important role in balance performance, and that strengthening the intrinsic foot muscles may be an effective way to improve balance.

Effects of Saccular Function on Recovery of Subjective Dizziness After Vestibular Rehabilitation.
Objective: We attempted to investigate whether the integrity of saccular function influences the severity of subjective dizziness after vestibular rehabilitation in vestibular neuritis. Study Design: Retrospective analysis. Setting: Tertiary referral center. Patients: Forty-six patients with acute unilateral vestibular neuritis were included. Interventions: Diagnostic, therapeutic, and rehabilitative. Main Outcome Measures: All the patients completed vestibular rehabilitation therapy until their computerized dynamic posturography and rotary chair test results were significantly improved. The rehabilitation patients were classified into the normal to mild subjective dizziness and moderate to severe subjective dizziness groups according to the dizziness handicap inventory score (cutoff of 40). Differences between the two groups were analyzed. Results: After rehabilitation, 32.6% of the patients still complained of moderate to severe dizziness. Age, sex distribution, the presence of comorbidities, caloric weakness, pre- and postrehabilitation gain values in rotary chair test, postrehabilitation composite scores in posturography, and the duration of rehabilitation were not significantly different between the two groups. However, initial dizziness handicap inventory (DHI) score and composite score in dynamic posturography were worse and the proportion of patients with absent cervical vestibular-evoked myogenic potential in the moderate to severe group was much higher (93.3% vs. 35.5%, p

ObjectivesThe study aimed to investigate the effects of age, gender, level of education, experience, and class level taught on the perception of voice handicap by Kuwaiti teachers using the Arabic version of the Voice Handicap Index (VHI-Arab). The mean VHI scores of Kuwaiti teachers were compared with those of Jordanian and Emirati teachers.MethodsThe study had a cross-sectional survey design. A total of 460 individuals (100 controls and 360 teachers) participated in this study and completed the paper copy of the VHI-Arab. We recruited 360 teachers, 180 males and 180 females (age range: 20–50 years), from 60 schools in 6 Kuwaiti districts. Teachers' VHI scores were compared with 100 nonteaching voice users (50 males and 50 females, with an age range of 18–42 years).ResultsFemale teachers scored significantly higher than male teachers in all subscales (ie, physical: P = 0.02; emotional: P = 0.007; total: P = 0.017), except for the functional subscale (P = 0.147). Elementary school teachers scored significantly higher than teachers of other levels (middle and high school) in all VHI subscales (physical: P = 0.047; emotional: P = 0.01; total: P = 0.039), except for the functional subscale (P = 0.47). The mean score of Jordanian teachers was higher than that of Kuwaiti and Emirati teachers in all VHI subscales.ConclusionsTeachers with a more favorable teaching environment scored better on the VHI. Gender differences were found in all the Arabic nationalities studied. Female teachers of the elementary level, in particular, should be the focus of attention of efforts to prevent voice damage.

Relationship between dietary quality, tinnitus and hearing level: data from the national health and nutrition examination survey, 1999-2002.
Int J Audiol. 2017 May 27;:1-7
Authors: Spankovich C, Bishop C, Johnson MF, Elkins A, Su D, Lobarinas E, Le Prell CG
Abstract
OBJECTIVE: To examine the relationship between the healthy eating index (HEI), a measure of dietary quality based on United States Department of Agriculture recommendations and report of tinnitus.
DESIGN: This cross-sectional analysis was based on HEI data and report of tinnitus.
STUDY SAMPLE: Data for adults between 20 and 69 years of age were drawn from the National Health and Nutrition Examination Survey (NHANES), 1999-2002. The NHANES is a programme of studies, to assess the health and nutritional status of adults and children in the United States. Two thousand one hundred and seventy-six participants were included in the analytic sample.
RESULTS: Of the sample, 21.1% reported tinnitus within the past year and 11.7% reported persistent tinnitus, defined as tinnitus experienced at least monthly or greater. Controlling for age, sex, race/ethnicity, diabetes, noise exposure and smoking status, we found that with healthier diet (poorer vs. better HEI) there was decreased odds of reported persistent tinnitus [odds ratio (OR); 0.67; 95% confidence interval (CI) 0.45-0.98; p = 0.03].
CONCLUSIONS: The current findings support a possible relationship between healthier diet quality and reported persistent tinnitus.

Carotidynia
From Wikipedia, the free encyclopedia
Carotidynia is a syndrome characterized by unilateral (one-sided) tenderness of the carotid artery, near the bifurcation. It was first described in 1927 by Temple Fay.[1] The most common cause of carotidynia may be migraine, and then it is usually self-correcting. Common migraine treatments may help alleviate the carotidynia symptoms. Recent histological evidence has implicated an inflammatory component of carotidynia, but studies are limited.[2] Carotid arteritis is a much less common cause of carotidynia, but has much more serious consequences. It is a form ofgiant cell arteritis, which is a condition that usually affects arteries in the head. Due to this serious condition possibly causing carotidynia, and the possibility that neck pain is related to some other non-carotidynia and serious condition, the case should be investigated by a medical doctor.[3]Because carotidynia can be caused by numerous causes, Biousse and Bousser in 1994 recommended the term not be used in the medical literature.[4] However, recent MRI and ultrasound studies have supported the existence of a differential diagnosis of carotidynia consistent with Fay's characterization.[5][6]

Abstract
Carotidynia is a syndrome characterized by tenderness of the carotid artery near the bifurcation due to numerous, heterogeneous causes. Here we reported the case of a 31-year-old Moroccan woman with right-sided neck pain and tenderness with irradiation to ipsilateral ear, eye, and occipital region. Clinical symptoms and imaging findings were suggestive of primary variant of carotidynia syndrome. In particular, color-Doppler ultrasonography revealed a concentric wall thickening of the distal common carotid artery, while thoracic magnetic resonance showed localized perivascular enhancement of the soft tissue in the right medial-distal common carotid artery in T1-weighted images, without intraluminal diameter variation. Moreover, careful clinicoserological and imaging investigations (cranial, cervical, and thoracic angiocomputed tomography and magnetic resonance) excluded well-known disorders potentially responsible for carotidynia syndrome. The patient was scarcely responsive to nonsteroidal anti-inflammatory drugs, but clinical symptoms resolved after three months. Of interest, the patient showed latent Mycobacterium tuberculosis infection (positive tuberculosis interferon-gamma release assay; QuantiFERON-TB Gold); this finding suggested a possible triggering role of mycobacterial antigens in the immune-mediated mechanism responsible for localized carotid injury.

Abstract
A 44-year-old woman presented with contralateral recurrence of carotidynia during steroid therapy at 1 month after onset. Carotidynia can present with a multiphasic clinical course and can affect the neck bilaterally. Therefore, patients with carotidynia should be observed even after remission.

Abstract
A 38-year-old man presented with a 19-year history of sore throat and an ache radiating from the centre of the anterior neck to the both ears and the occiput. Computed tomography angiography revealed a tortuous submucosal right internal carotid artery, which was causing tonsillar displacement. The diagnosis of carotidynia has a controversial history within the literature and is currently not accepted as a distinct pathological entity by the International Headache Society. In this patient, the clinical and imaging features, in addition to the absence of any other pathology confers support to the diagnosis of carotidynia.

Abstract
Carotidynia is a self-limiting, idiopathic clinical syndrome characterized by acute unilateral neck pain and tenderness of the carotid artery. We describe a unique case of bilateral carotidynia that occurred metachronously, with each incident resolving without long-term sequelae. Knowledge of this entity is important to properly interpret the imaging findings and to not mistake this finding as an ill-defined tumor, thus avoiding unnecessary biopsy.

Abstract
Carotidynia is rare and associates neck pain with tenderness to palpation usually over the carotid bifurcation, the diagnosis of which is based on magnetic resonance imaging (MRI). Ultrasounds (US) are also frequently used but their accuracy in predicting the course of the disease is unknown. We are reporting the case of a 52-year-old man who presented a typical carotidynia. Clinical symptoms, ultrasound and MRI imaging evolution were closely correlated. Our case suggest that after a first MRI to set a positive diagnosis of carotidynia and exclude differential diagnoses, US which is more widely available and less expensive could constitute the imaging of reference for the follow-up.

Abstract
Idiopathic carotidynia is a syndrome characterized by pain and tenderness over the carotid artery without an associated structural luminal abnormality. Controversy exists over whether this is a distinct disease entity or merely a symptom attributable to other causes of neck pain, such as carotid dissection or vasculitis. A 50-year-old woman presented with sudden-onset right neck pain. Imaging studies demonstrated transmural inflammation of the proximal internal carotid artery, without evidence of intraluminal pathology. The patient was placed on low-dose aspirin and ibuprofen. Her symptoms resolved within a week. At 3-month follow-up, her carotid artery appeared normal on duplex ultrasonography.

Abstract
BACKGROUND AND PURPOSE:
The differential diagnosis of acute cervical pain includes nonvascular and vascular causes such as carotid dissection, carotid occlusion, or vasculitis. However, some patients present with unclassified vascular and perivascular changes on imaging previously reported as carotidynia. The aim of our study was to improve the description of this as yet unclassified clinico-radiologic entity.
MATERIALS AND METHODS:
From January 2009 through April 2016, 47 patients from 10 centers presenting with acute neck pain or tenderness and at least 1 cervical image showing unclassified carotid abnormalities were included. We conducted a systematic, retrospective study of their medical charts and diagnostic and follow-up imaging. Two neuroradiologists independently analyzed the blinded image datasets.
RESULTS:
The median patient age was 48 years. All patients presented with acute neck pain, and 8 presented with transient neurologic symptoms. Imaging showed an eccentric pericarotidian infiltration in all patients. An intimal soft plaque was noted in 16 patients, and a mild luminal narrowing was noted in 16 patients. Interreader reproducibility was excellent. All patients had complete pain resolution within a median of 13 days. At 3-month follow-up, imaging showed complete disappearance of vascular abnormalities in 8 patients, and a marked decrease in all others.
CONCLUSIONS:
Our study improved the description of an unclassified, clinico-radiologic entity, which could be described by the proposed acronym: TransIent Perivascular Inflammation of the Carotid artery (TIPIC) syndrome.

Abstract
A YOUNG or middle-aged women reported to her physician because of a sore throat, without fever or other constitutional manifestations, which may have been present for weeks or months. The patient believes that the glands in the neck are swollen. These "swollen glands" are said to act strangely: sometimes the swelling lasts only a few hours, sometimes it persists for weeks; it disappears mysteriously and recurs frequently. During the course of the physical examination the physician finds no abnormality, but when he re-examines the neck and follows the directions given by the patient, he finds a tender swelling that could be an inflamed lymph node.
The patient then is treated with a sulfonamide or with penicillin, and, when no relief ensues, a course of one of the broad-spectrum antibiotics is administered. This therapeutic program also is unsuccessful, and the harried physician begins to think of other possibilities. Since the patient has "swollen glands," feels weak, tired, and run-down, and antimicrobial therapy has not helped, a diagnosis of infectious mononucleosis may be considered. But, results of a heterophil antibody test are negative, and the diagnosis is changed to possible viral infection.
After several weeks or months of having diagnoses changed, the nervous patient can sense that her physician is uncertain, and she begins to worry about the looming possibility of cancer. She keeps poking in the region of the soreness, and the area becomes even more tender. In desperation, further investigations are carried out and nothing definitely abnormal is found. Teeth . . .
