NCT ID: NCT06316752 Recruiting - Observational Study Clinical Trials

The Natural History of Sialidosis Type I

Start date: March 15, 2022
Phase:
Study type: Observational

Sialidosis type 1 is an autosomal recessive disorder caused by bialleic NEU1 gene mutations. Patients with sialidosis type I present variable neurological and eye dysfunction and the progression rate is variable. The goal of this protocol is to assess the neurological and ophthalmological status of these patients and characterize the clinical and laboratory abnormalities in order to determine the natural history of the disease. Patients will be followed every 6 month with comprehensive clinical, neurological and ophthalmological examinations combined with neuropsychological, blood, radiological and electrophysiological tests.

NCT ID: NCT05359367 Recruiting - Stroke Clinical Trials

A Novel Approach to Enhance True Recovery After Stroke

Start date: November 29, 2023
Phase:
Study type: Observational

The purpose of this study is to elucidate pathophysiological mechanisms behind gait disturbances during the early recovery phase after hemiparetic stroke to identify targets for new treatment strategies. Using an explorative, observational study design, pathophysiological mechanisms at play during the early recovery phase will be monitored, by repeated clinical assessments during inpatient rehabilitation as well as examinations of muscle activation patterns, kinematics of walking, corticospinal and reticulospinal function < 1 month, 3 and 6 months after hemiparetic stroke. Inclusion: Eligible patients will have suffered a stroke, verified by CT or MRI examination and are admitted to inpatient care at the University Department of Rehabilitation Medicine Danderyd Hospital (RUDS). Thirty patients will be included consecutively. With an anticipated loss of 4-10 patients, at least 20 are expected to complete the study. The clinical assessment protocols include standardized measures for the assessment of clinical and self-perceived aspects of functioning and disability. These assessments will be performed and repeated < 1 month, at 3 months and 6 months post-stroke by a therapist not responsible for rehabilitation interventions. At each of these assessment instances, laboratory movement analysis including electromyography (EMG) and ultrasound of the lower extremity muscle will be performed. In addition, a short assessment of body function and activity will be performed weekly during inpatient rehabilitation.

NCT ID: NCT01983059 Recruiting - Observational Study Clinical Trials

Swiss Liver Venous Thrombosis Study

SLVTS-SASL-35
Start date: March 18, 2014
Phase:
Study type: Observational

The Liver Venous Thrombosis Study is a prospective observational cohort study aimed at collecting clinical data, patient reported outcomes and biological samples of all patients who have been newly and previously diagnosed with liver venous thrombosis in one of the participating hospitals in- and out-patient clinics of the participating centers in Switzerland. All new patients diagnosed with liver venous thrombosis or patients who are currently being treated in one of the participating centers, will be asked to participate in the study.
