Active clinical trials for "Movement Disorders"

This investigator initiated trial is designed to measure the accuracy of diagnosis of Parkinson disease through the use of DaTscan. Currently, DaTscan is FDA approved to measure dopamine transporter densities in human tissue. This measurement can assist in distinguishing between Essential Tremor and Parkinsonian Syndromes (idiopathic Parkinson disease, Progressive Supranuclear Palsy, Multi Systems Atrophy, etc). This study will compare both clinical diagnosis of symptoms and the results of the scan to the pathological diagnosis received at time of death. Patients will be registered in the Parkinson Research Institute's brain donation program, receive a clinical diagnosis of Parkinson disease, have their brain scanned using DaTscan, and donate their tissue for research and autopsy purposes. The hypothesis of the study is that DaTscan will diagnosis Idiopathic Parkinson Disease as accurately as a clinician.

There is association between eye movement disorder and cognitive dysfunction. Therefore, utilizing eye movement and screening for cognitive dysfunction is feasible. In the present study, we will develop an artificial intelligence platform to screening for cognitive dysfunction by inspecting the function of eye movement. Futher more, based on the screening results, the platform will offer referral suggestions.

this study is to explore the degree of impairement in movement skills in children with autistic spectrum disorders

This is a descriptive, observational, longitudinal, prospective study consecutively enrolling patients with non-specific neck pain and age-matched asymptomatic participants. The investigators will register sensorimotor control variables, including active range of motion, movement speed, acceleration, smoothness of motion, head repositioning accuracy and motion coupling patterns. These variables will be recorded by means of Inertial Measurement Unit (IMU) sensors during the following tests consecutively performed in two measuring sessions separated by 12 months: (a) kinematics of planar movements, (b) kinematics of the craniocervical flexion movement, (c) kinematics during functional tasks and (d) kinematics of task-oriented neck movements in response to visual targets.

Patients from 60 to 75 years old diagnosed with cerebral small vessel disease with no history of symptomatic stroke, brain tumor, traumatic brain injury, seizures and neurodegenerative or mental disorder will undergo overnight leg actigraphy and cardiorespiratory monitoring. Those of them with apnea/hypopnea index under 5 will be enrolled. Brain MRI and cognitive assessment will be performed at baseline and in 1-year follow-up, sleep quality will be assessed at baseline with self-reported questionnaires. Progression of cerebral small vessel disease markers and cognitive dysfunction will be compared between patients with high periodic limb movement index (the number of periodic limb movement ≥ 15 per hour of sleep) and controls (periodic limb movement index < 15/h).

In the study, NextGen SE are on-hand a cohort comprising each 50 pediatric and 50 adult patients, and in which there are an unclear movement disorder or an unclear cognitive disorder, examines the following questions : Primary: Number of diagnoses made by NGS Secondary: restriction of the quality of life by unclear disease Cost of not purposeful preliminary diagnostics ( beyond the minimal diagnostic data set ) Impact of the diagnosis to therapy and follow-up examinations Time to diagnosis

Objectives: Upper eyelid retraction was believed to be maintained solely by voluntary contraction of the levator palpebrae superioris (LPS) and frontalis muscles, together with involuntary contraction of the sympathetically innervated Müller's muscle (MM). However, several studies have suggested that the LPS also undergoes involuntary contractions, and that a visual stimulus may not be the only trigger for frontalis muscle contractions. Recent studies hypothesized that the MM contains proprioceptive neuronal structures, which elicit involuntary LPS muscle contraction by the mesencephalic trigeminal nucleus via a continuous stretch reflex. We aim to identify proprioceptive structures in MM by means of histological examinations. Methodology: Prospective study. Collaboration of oculoplastics, ophthalmologists and a neuroanatomy specialist in Sheba Medical Center. 50 fresh MM specimens from patients undergoing Müllerectomies will undergo histologic examinations, including immunohistochemical staining and light and electron microscopy. Significance: Identification of proprioceptive structures in MM will be the first evidence-based proof of a proprioceptive mechanism in the eyelid. This might have a significant impact on future surgical management of eyelid procedures. Comprehensive understanding of the mechanisms underlying eyelid function is especially important in the management of children with ptosis who may have coexisting amblyopia.
