Summary: This study is an observational longitudinal study involving the use of MRIs and video recordings taken at home of patients completing basic tasks. Once consent is obtained, subjects will be asked to schedule an appointment with radiology to undergo the listed MRIs of the heart and/or muscle. Subjects will also be given instructions on how to use the video recording app on their personal devices, o...

Summary: The purpose of this study is to learn more about the effectiveness of palliative care training for community physicians and telemedicine support services for patients and carepartners with Parkinson's disease and Lewy Body Dementia (LBD) or related conditions and their care partners. Palliative care is a treatment approach focused on improving quality of life by relieving suffering in the areas of...

Summary: The overall goal of this protocol is to evaluate the imaging characteristics of [18F]PI-2620 using positron emission tomography (PET) in patients with progressive supranuclear palsy, Richardson's syndrome (PSP-RS)

Summary: The study aims to investigate ocular motor and sensory outcomes of two different strategies of lateral rectus recession; symmetric and asymmetric, in management of basic type intermittent exotropia with ocular dominance.

Summary: This pilot study is perfomed to validate and document faisability of the use of Frenzel lens and the use of a diagnostic algorithm for the assessment of a special sign (nystagmus) observe in the eyes of patients consulting in the emergency department for an acute episode of vertigo/dizziness/imbalance.

Summary: This is an interventional therapy study designed to evaluate the efficacy of a two-week intervention, i.e. training with a specialized exhalation training device (called expiratory muscle strength training; EMST150 or EMST75; Aspire Products, Gainsville, FL) on swallowing function in patients with neurodegenerative Parkinsonian disorders. This study involves a routine endoscopic evaluation of swal...

Summary: Our hypothesis is that botulinum toxin injections (with onabotulinum toxin, incobotulinum toxin, and abobotulinum toxin) given at 10-week or shorter intervals for the indication of treatment of muscle spasms associated with neurological disorders are associated with equal safety and effectiveness as those given at 12-week or longer intervals. We also hypothesize that for those patients who would p...

Summary: Infants with and without torticollis will be measured at different time points to assess their passive cervical spine range of motion (pCROM).

Summary: Study of Ingrezza (Valbenazine) for the treatment of cervical dystonia.

Summary: The purpose of this research study is to see how well the treatment of a participant's eye coordination and/or focusing problems improves eye muscle responses and symptoms of eyestrain. We will use an entertainment device called a virtual reality headset to play a custom-designed video game to find out how well the treatment of binocular vision improves a participant's coordination and/or focusing...

Summary: Our successful R01 discovered 1) the neural mechanistic difference between typically occurring convergence insufficiency (TYP-CI) and binocularly normal controls and 2) the underlying mechanism of office-based vergence and accommodative therapy (OBVAT) that is effective in remediating symptoms. Adolescent and young adult concussion is considered a substantial health problem in the United States wh...

Summary: This is an open-label, multi-centre study in subjects with a genetically confirmed mitochondrial deoxyribonucleic acid (DNA) transfer ribonucleic acid (tRNA)Leu(UUR) m.3243A>G mutation who completed study KH176-202. In the KH176-203 study subjects will be receiving KH176 100 mg BID or KH176 50 mg bid in die (BID) (as determined by the investigator based on safety / tolerability considerations) for...
