Active clinical trials for "Nerve Compression Syndromes"

The primary aim of this study is to discover whether patients with CMT type 1 and 2 have neuromuscular junction transmission deficits. The secondary aim is to collect information of different clinical and electrophysiological test procedures to perform possible future clinical trials in CMT patients.

This trial is studying Electrical Impedance Myography (EIM) for measuring muscle health. The trial is studying people with Amyotrophic Lateral Sclerosis (ALS), other neuromuscular diseases, and healthy volunteers to see if the EIM device can measure disease in muscle tissue.

CMT is a rare disease for which novel treatments are being developed. Evaluation of intervention efficacy is hampered by slow progression and lack of sensitive outcome measures. Primary goal of the project is to identify and validate RNA and protein derived biomarkers in blood of CMT patients for selected outcome measures over 2 years. The investigators expect to develop more responsive outcome measures and circulating biomarkers to improve assessment of intervention efficacy in forthcoming therapeutic trials.

The long term goal of this proposal is to precisely characterize the auditory and vestibular abilities of children with Charcot-Marie-Tooth (CMT) and how these abilities evolve during the progression of the disorder. This information will be used to refine the management methods for hearing loss and vestibular disorders in these patients. Given that the phenotypic severity is variable within the CMT patient population, we predict that not all CMT patients will present with auditory and vestibular dysfunction. We will therefore collect specimens (i.e., buccal swabs and saliva) from study participants so that their DNA can be isolated and used to determine the genetic basis for auditory and vestibular dysfunction in peripheral neuropathies.

Charcot-Marie-Tooth 4J (CMT4J) is a rare inherited peripheral neuropathy often characterized by rapidly progressive, asymmetrical upper and lower extremity weakness, muscle atrophy leading to loss of ambulation, respiratory compromise and premature death with no available treatment. The purpose of this study is to investigate the clinical characteristics and natural clinical progression of symptoms in individuals with CMT4J. This natural history study is important to better understand disease course to be able to determine clinically meaningful outcome measures for use in future clinical trials.

The purpose of this research study is to create and validate two patient reported outcome (PRO) questionnaires. PRO questionnaires ask questions that help to measure disability in patients with inherited neuropathies. These questionnaires ask questions about what participants think disability is for themselves or others with inherited neuropathies. These questionnaires are a useful tool when evaluating whether treatments are working in the day to day life of an individual, although there are currently no questionnaires available specifically for people who have Charcot Marie Tooth disease (CMT).

Charcot-Marie-Tooth (CMT) disease is the most common inherited peripheral neuropathy. Foot deformities are frequent complications in CMT patients and orthopaedic surgery is often required. As yet there are no systematic studies on the management of orthopaedic complications in CMT patients and the current approach varies between centres. This study is a survey with the aim of understanding the current surgical approach to orthopaedic complications in CMT. The target population includes orthopaedic surgeons who perform surgical procedures for foot deformities in CMT patients attending centres participating in the Inherited Neuropathies Consortium (INC).

The aim of this study is in a prospective, consecutive series of diabetic patients with carpal tunnel syndrome, who are then age and gender matched with non-diabetic patients having idiopathic carpal tunnel syndrome to compare the clinical results after carpal tunnel release.

The study is aimed to test the hypothesis that there is anticipation in CMT

The project will develop knowledge about physical activity in persons with Charcot-Marie-Tooth (CMT) in Norway. We plan to explore instruments to measure physical activity level for the target-group at the community level. We want to understand which type of activities, activity intensities and how persons with CMT perform habitual physical activity. Subsequently, a physical activity measurement instrument adapted to persons with CMT will be developed. This instrument can be used in a future intervention project to promote physical activity in this group.
