Chronic headaches are associated with changes in brain structure and function that may be associated with increased suffering and disability. Understanding how Osteopathic Manipulative Therapy (OMT) affects these changes would reveal new insight into how the brain processes pain and returns to normal function. Also, demonstrating these changes would provide evidence regarding how OMT causes a reduction in pain and disability, supporting the recommendation for OMT as a primary treatment option for headaches.

The aim of the study is to evaluate the effectiveness of an aqueous solution containing CBD and CBN in the management of Facial Pain and Headache of Muscular Origin. A randomized (block randomization), double-blind, two-arm controlled trial will involve 42 adult patients diagnosed with Facial Pain and Headache of Muscular Origin which is lasting more than 3 months on the basis of clinical examination. Qualified study participants will be randomly assigned to two groups. The studied group will receive tan aqueous solution containing CBD and CBN, to drink at home in the dose determined by the attending physician, while the control group will receive an aqueous solution of placebo, to drink at home in the dose determined by the attending physician during this time. Each subject will be tested on the qualification day (D0), on 20 days after D0 (D20), and then 40 (D40) and 60 (D60) days after the qualification day using electromyography (EMG), pressure pain threshold test (PPT), clinical examination and surveys.
NCT07418723
This project was an empirical single-case experimental design (SCED) study conducted as part of a DClinPsy doctoral thesis completed by one of the researchers. The study used a brief and highly personalised psychological intervention for adolescents experiencing headaches. The aim was to understand how participants' real-time data could guide the personalised intervention provided to adolescents, including the development of skills to cope with headaches. The study began with an initial assessment of adolescents' (n = 6-8) headache experiences. Following this, the researchers formulated an individualised diagram for each participant to identify central problem areas or problematic responses relevant to their headaches. Based on these formulations, the team delivered a brief personalised intervention focused on developing adaptive psychological skills and coping responses. The intervention consisted of 4-5 weekly, 30-minute, one-to-one online sessions, targeting headache-related areas of concern. These sessions drew from established Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment Therapy (ACT) interventions, both of which have previously been shown to reduce headache-related disability and improve functioning. During data collection, adolescents were prompted to complete brief online questionnaires on their smartphones. The questionnaires were personalised to each participant and measured specific psychological processes that had been identified as target areas during the assessment and formulation stages. This personalised data collection approach was then used to analyse individual-level changes and to explore how these changes facilitated progress in areas identified as important to each adolescent (e.g., school involvement or extracurricular activities). The study also examined whether overall headache-related disability decreased and whether daily functioning improved following the completion of the intervention.

NCT07176988
This research study aims to evaluate the effect of treatment delivery method on voice outcomes over 12 months in people with a primary complaint of a voice problem, diagnosed with either non-phonotraumatic vocal hyperfunction, also known as primary muscle tension dysphonia (MTD) or phonotraumatic vocal hyperfunction, also known as benign vocal fold lesions (lesions). The secondary objectives are: * To evaluate acoustic correlates of clear speech and the relationship to vocal acoustic and patient-reported voice outcomes. * To determine the association between overall dysphonia outcomes and adoption of clear speech.
NCT04710862
Primary muscle tension dysphonia is a voice disorder that involves excessive and poorly coordinated muscle activity affecting multiple subsystems that are involved in speech production, in the absence of structural or neurologic abnormalities of the larynx. Primary muscle tension dysphonia (MTD) is one of the most common forms of voice disorders, accounting for at least 40% of patients seen in voice clinics. Perceptually the voice sounds hoarse and strained, with reduced loudness and pitch range, and people with MTD find speaking very effortful and fatiguing. The physiological abnormalities that characterize MTD are considered multifactorial, and include over-activity of muscles in and around the larynx, laryngeal constriction patterns, and abnormal speech breathing patterns. However, standard treatment approaches for MTD primarily address laryngeal function, including repositioning of laryngeal structures, reducing activity in the intrinsic and extrinsic laryngeal muscles, and altering vibratory patterns. Although voice improvement may follow these treatments, many people with MTD show recurrence of voice problems after only a few months, and some do not improve with treatment. These findings highlight the need for alternative treatments that address the respiratory contributions to MTD, which directly affect the phonatory system. The goal of this project is to compare the effects of two respiratory-based training conditions in people with MTD. A randomized group design will be implemented to determine the respiratory and acoustic effects of each condition. We will determine the effects of each condition immediately after and then 3 and 6 months after training completion to assess short- and long-term training effects. We propose that respiratory training will have a positive effect on related laryngeal behavior and voice. The proposed project has the potential to substantially advance the evidence-based treatment options for MTD, providing a vital step toward reducing the debilitating effects of this disorder.

NCT06689696
The goal of this clinical trial is to learn if a new contact lens device can record patterns in eye pressure for 24 hours in adults with glaucoma and in healthy participants. The main questions it aims to answer are: * Is the contact lens device able to detect patterns in eye pressure that happens naturally between nighttime and daytime? * Are the contact lens recording patterns similar when repeated one week later? * What eye problems do participants have when wearing contact lens for up to 24 hours? Researchers will compare if the recordings detected by the contact lens over 24 hours are similar to the patterns measured by an eye pressure measuring instrument used in a doctor's office. Participants will * Wear contact lens in one eye for up to 24 hours * Take recordings in that eye with smartphone camera every 15 minutes when awake * For those participants who are able to stay overnight at a hotel for the trial, researchers will measure the eye pressure in the other eye every 1 to 2 hours when awake with an eye pressure measuring instrument.

Glaucoma is characterized by a progressive loss of retinal ganglion cells (RGCs) leading to optic nerve head (ONH) damage and associated visual field defects. The main risk factor for glaucoma is elevated intraocular pressure (IOP). Reducing IOP slows down the progression of the disease as several large multicenter trials have shown. Some patients, however, still progress despite adequately controlled IOP. As such, there is considerable interest in approaches that rescue RGCs independent of IOP, a strategy called neuroprotection. Although this field was actively discovered in the last 20 years in the brain and the eye, no non-IOP related treatment is clinically available to date. Various approaches are currently studied in some detail. One interesting strategy focuses on the neurovascular unit. The blood flow of the human retina is controlled by complex mechanisms that include myogenic, metabolic and hormonal factors. The high consumption of oxygen in the human retina is crucial for normal functioning of the organ. As in the brain, blood flow in the retina is also controlled by neurovascular coupling. This means that the retina increases its blood flow to regions in which neurons are activated. This is done in an effort to provide more oxygen and glucose to the active neurons. In the recent years evidence has accumulated that astrocytes play a key role in mediating this vasodilator signal. In the brain, abnormalities in neurovascular coupling have been observed in diseases like stroke, hypertension, spinal-cord injury and Alzheimer's disease. This break-down of neurovascular coupling is considered to play a key role in neuronal death in these diseases. In the retina, abnormalities in neurovascular coupling have been observed in diseases as diabetes and glaucoma. Most of the data obtained in the human retina stem from a system that measures retinal vasodilatation during stimulation with flickering light. The investigators have previously shown that flicker stimulation of the retina is, however, also associated with a pronounced increase in retinal blood velocities. In this study the investigators employed laser Doppler velocimetry (LDV) for the measurement of retinal blood velocities, but this technique is not clinically applicable because it requires excellent fixation of the subject under study. In the present study, the investigators propose to use an alternative system for neurovascular coupling that they have developed recently. In this approach, the investigators use bi-directional Fourier-domain optical coherence tomography for the assessment of retinal blood flow. Optical coherence tomography (OCT) is a non-invasive optical imaging modality enabling cross-sectional tomographic in vivo visualization of internal microstructure in biological systems. In ophthalmology, OCT has become a standard tool in visualizing the retina and nowadays is considered also as a standard tool in the diagnosis of retinal disease. In the recent years, conventional time domain OCT was replaced by Fourier domain OCT providing significantly improved signal quality. This bidirectional system overcomes the limitations of previously realized techniques, which include doubtful validity and limited reproducibility. In addition, pattern ERG, multifocal ERG and oscillatory potentials will be measured to allow for concomitant assessment of neural function. The investigators seek to measure neurovascular coupling in the human retina in patients with early primary open angle glaucoma (POAG), normal tension glaucoma, ocular hypertension and a healthy control group. In order to obtain information on neurovascular coupling, both neuronal function as well as retinal blood flow need to be measured. In the present study, the investigators will employ pattern ERG, multifocal ERG as well as oscillatory potentials to assess the function of the inner retina. Retinal blood flow through major retinal arterial and venous branch vessels will be measured before, during and after flicker stimulation with the dual-beam bidirectional Fourier Domain Doppler OCT coupled to the commercially available Dynamic Vessel Analyzer (DVA) produced by IMEDOS, Jena, Germany, which provides adequate resolution to study the retinal circulation.
NCT05970562
Vocal hyperfunction (VH) is the most commonly treated class of voice disorders by speech-language pathologists and voice therapy is the primary curative treatment. Patients and clinicians report that generalizing improved voicing into daily life is the most significant barrier to successful therapy. We will test if extending biofeedback into the patient's daily life using ambulatory voice monitoring will significantly improve generalization during therapy and if individual patient factors, like how easily they can modify their voice and engagement during therapy, moderate the effects of the biofeedback.

NCT05493098
Tension-type headache is a widespread disorder, with a lifetime prevalence in the general population ranging between 30% and 78%. Tension-type headache also places a financial burden on society and individuals. Myofascial pain can reduce the range of motion and patterns of muscle activation and play an important role in tension-type headache. Based on the previous studies, dry needling can reduce local and referred pain, increase range of motion and improve patterns of muscle activation in patients with myofascial pain syndrome. The effectiveness of dry needling in patients with tension-type headache is not fully known. Objective: The aim of this study will be to investigate the effectiveness of dry needling on pain, active range of motion, functional disability, and frequency of headache in patients with episodic tension-type headache. Method: This study will be a double-blind randomized controlled trial. Thirty-six patients with episodic tension-type headache will be randomly divided into two groups: the experimental group (dry needling and routine physical therapy) and the control group (sham dry needling and routine physical therapy). The primary outcomes will be pain intensity and active range of motion of the craniocervical region. Functional disability and frequency of headache will be considered secondary outcomes. Outcomes will be assessed before and one week after the intervention.

The IOL-capsular complex is formed after cataract surgery and intraocular lens (IOL) implantation.Early postoperative mechanical wrapping of the anterior and posterior capsules plays a significant role in preventing IOL decentration and tilt, as well as formation of the IOL-capsular complex which reduces the incidence of posterior cataract opacity. Capsular tension rings were first introduced in the early 1990s for loosening and tightening the lens bag and maintaining the equatorial contour of the bag after cataract surgery.Today, capsular tension rings of many different designs are in use.The capsular tension rings can be used in eyes with fragile and split zonular fibers, as well as pseudoexfoliation, high myopia, Marfan syndrome, mature cataract and lens subluxation.The capsular tension ring reduces the incidence of decentration and tilt of the IOL by reducing capsular contraction. In addition, multi-focus IOL implantation combine with capsular tension ring result in smaller high-order aberrations in our eyes compared to cataract surgery with multi-focus IOL implantation alone.For patients with high myopia, they often have a longer axial length and a larger capsule diameter, which reduces the rotational stability of the IOL and may lead to tilt ,decentration and displacement of IOL.Currently, there is no literature guidance to compare the results of cataract surgery combined with or without capsular tension ring implantation in patients with high myopia.Our hospital has Swept-source Optical Coherence Tomography ( SS-OCT,Casia2, TOMEY, Japan), which can accurately photograph the process of IOL capsule bending and the changes of lens position after cataract surgery. SS-OCT can be used to evaluate the influence of capsular tension ring on the dynamic changes of IOL-capsular complex in patients with high myopia after cataract surgery.
NCT04651530
