Filter by:Tinnitus is the awareness of a sound in the ear or head without any outside source. It affects around 15% of people in the UK. About 20% of people with tinnitus experience symptoms that negatively affect their quality of life including sleep disturbances, difficulties with hearing and concentration, social isolation, anxiety, depression, irritation or stress. Most common clinical management strategies for tinnitus include education and advice combined with some form of sound therapy. The effects of these management options are, however, variable. Currently, the exact aetiology of tinnitus is unknown although maladaptive plasticity due to sensorineural hearing loss is thought to play a big role. Neuroimaging studies have pointed to over-activation or excessive spontaneous activity within the central auditory cortex. Furthermore, electrophysiological techniques have confirmed the frontal cortex's role in tinnitus through dysfunctional top-down modulation. Transcranial direct current stimulation (tDCS) is a neurostimulation technique in which weak currents (1-2 mA's) are delivered to the brain, thereby depolarising or hyperpolarising neurons within the desired region of cortex. tDCS is a non-invasive and easy to apply tool, delivered by applying two surface electrode to a patients head. It has previously been used as a treatment for depression, stroke rehabilitation, and cognitive enhancement. Some studies have indicated potential benefit of tDCS in tinnitus patients, but this has not yet been investigated within the UK. Neuromodulation therapies should deliver a permanent reduction in tinnitus percept by driving the neuroplastic changes necessary to interrupt abnormal levels of oscillatory cortical activity and restore typical levels of activity. This change in activity should alter or interrupt the tinnitus percept (reduce or extinguish) and this should be concomitant with a change in the level of self-reported tinnitus handicap. The currently ongoing Cochrane review of neuromodulation (desynchronisation) for tinnitus in adults found mixed evidence for the electrical stimulation therapies for tinnitus, including tDCS. However, the review also found that the most recent tDCS trials that have used greater numbers of treatment sessions found significant reductions in tinnitus symptom severity, anxiety, and depression. Authors concluded that these findings warrant further trials of tDCS. Research studies using electroencephalography (EEG) or magnetoencephalography (MEG) suggested changes in oscillatory activity in different frequency bands that might be associated with tinnitus, however a consistent picture has not yet emerged. Reduction of this abnormal activity might signify a reduction in the level or perceived severity of TI and could potentially be used as a valuable indicator of the course of TI treatment. In this project specific changes in brain activity that happen during a new treatment approach for tinnitus - transcranial Direct Current Stimulation (tDCS)- will be investigated. This will help to determine how the treatment might work, whether specific brain activity may be a meaningful biological indicator or objective measure of tinnitus, and provide a reliable measure of treatment-related change; this has not yet been achieved in tinnitus research but is crucial.
Scuba Diving has become a popular hobby, for a leisure activity, diving puts the auditory system at the risk of a wide variety of complaints including tinnitus, Low level laser therapy is a new modality in treatment of tinnitus. This study evaluates effect of laser therapy on tinnitus of Scuba divers in Red Sea.
The goal of this study is to use non-invasive transcranial direct current stimulation (tDCS) combined with active listening therapy to treat tinnitus and hyperacusis and related conditions.
A European cross-sectional study was conducted with the aims of: i) examining inter-country differences in prevalence of tinnitus by comparing prevalence estimates in countries with relatively low versus high gross domestic product (GDP) per capita and comparing prevalence estimates in countries within different European regions (i.e., Northern, Southern, Eastern and Western Europe); ii) understanding the effect of sex, age, socio-economic variables, body mass index (BMI), and marital status on overall prevalence of tinnitus; iii) assessing the effect of hearing difficulty on tinnitus prevalence; and iv) exploring the effect of tinnitus severity on use of healthcare resource for tinnitus Overall, approximately 12,000 individuals aged 18 years or over are enrolled in 12 different European countries (BG, DE, ES, FR, GR, IE, IT, LV, PL, PT, RO, UK). Survey sample from each country were representative of the country-specific population in terms of sex, age, and socio-economic characteristics.
Tinnitus, the perception of sound in the absence of an external acoustic stimulus. Tinnitus is often perceived inside the head rather than the ear and is a common condition with a prevalence estimated between 10 and 15% in adults. Between 1 and 3% of this population are having a significant impact on their quality of life. Despite its high prevalence, the underlying mechanisms of tinnitus still remain unclear. The majority of tinnitus cases associated with some degree of hearing loss, making hearing loss the biggest risk factor for tinnitus. Recently, it has been suggested that hearing deficits, such as speech-in-noise difficulty, can exist in the absence of any overt hearing loss within the audiometric range (0.125-8 kHz). This is referred to as "hidden hearing loss" and has been suggested to be associated with hearing loss at above-audiometric (> 8 kHz) frequencies. This project is aimed at studying the underlying mechanisms of tinnitus and the possible relation with overt or hidden hearing loss. Specifically, the investigators want to test the hypothesis that tinnitus is caused by maladaptive plasticity arising as a result of auditory input deprivation. This idea is supported by the finding that tinnitus may disappear when the hearing, and thus auditory input, recover. Disruptions at lower levels of the auditory pathway could lead to alterations in synaptic transmission and neurotransmitter release in more central regions of the auditory system (e.g., in the auditory cortex). This may create an imbalance between neuronal excitation and inhibition, and re-routing of auditory pathways, leading to abnormal neural excitability and connectivity. In this study, the investigators question whether auditory cortex disinhibition is specifically related to tinnitus, or is a consequence of hearing loss. To answer this question, the investigators propose to conduct a study that aims to investigate the inhibition mechanism by quantifying GABA concentration level, neural activity and functional connectivity strength of auditory cortex using non-invasive imaging techniques, namely Magnetic Resonance Spectroscopy (MRS) and functional Magnetic Resonance Imaging (fMRI). The investigators expected to possibly provide a tinnitus biomarker, and this may help to direct future treatments.
The purpose of this study is to determine the efficacy of OTO-313 in subjects with unilateral tinnitus and to determine the safety and tolerability of OTO-313 in subjects with unilateral tinnitus.
The pelvic floor serves as stability and support as it is the postural balance and core resource base for the pelvic organs. A dysfunction in the organs in this area can affect the pelvic floor muscles, the functioning of an organs in the muscles. Incontinence organ prolapse, pelvic pain and sexual problems may occur when the support or stability of the pelvic floor is impaired. Pelvic floor novelization is not always seen weakness. Sometimes excessive contractions and excessive activity in muscle tone can be seen. Stress and anxiety-related tension are the main causes of pelvic floor dysfunctions. Involuntary contractions and excessive muscle tone in the pelvic floor muscles cause chronic pelvic pain syndrome, constipation and dyssynergic defecation problems. Some of these patients have complaints of tightening teeth in the temporamandibular joint, grinding teeth at night, together with contractions in the pelvic floor. The aim of this study is to investigate the effect of pelvic floor improvement on tinnitus level as a result of dysfunctional condition in temporamandibular joint with treatment practices of pelvic floor patients with excessive muscle activity.
Lateral Inhibition Therapy (TIL) corrects the patient's hearing by notched amplification on the patient's listening soundtrack. This half-octave notch is targeted at tinnitus frequencies measured tonal. The device slightly increases the amplification around the notch, so that the cerebral cortex compensates for this "gap" in the sound spectrum, masking the crippling tinnitus at the same time. This research is based on a new algorithm developed by the SIEMENS Company which proposes an attenuation of tonal tinnitus by a TIL by notched amplification emitted by the hearing device, object of the study.
This study will assess the effectiveness of highly bioavailable curcumin in suppressing subjective tinnitus based on pre- and post-treatment evaluations using the validated Tinnitus Functional Index (TFI) and Tinnitus Handicap Inventory (THI) surveys.
Objective: To determine the effectiveness of Intratympanic dexamethasone with lignocaine in control of idiopathic tinnitus. Methodology: 264 consenting patients with idiopathic unilateral tinnitus presenting at ENT Department were assessed for tinnitus severity using Modified Tinnitus Handicap Inventory and the scores recorded and subsequently administered intratympanically 2.0 ml (milliliter's) of dexamethasone and lignocaine (1.5 ml dexamethasone + 0.5 ml 1% lignocaine). The dose was repeated twice at weekly intervals. All patients were re assessed on Modified Tinnitus Handicap Inventory two weeks after third Intratympanic administration.
