View clinical trials related to Carpal Tunnel Syndrome.
Filter by:Carpal tunnel syndrome (CTS) is a common condition that still lacks a reliable, objective screening test. Many anatomical aspects of the syndrome have been studied including the dimensions of the carpal tunnel and shape of the nerve within the tunnel. The investigators have observed varying amounts of muscle overlying the carpal tunnel in patients undergoing surgery for the condition. Assuming that this muscle may have a dynamic role in the development of the condition, the investigators attempted to quantify this muscle using ultrasound (US). The purpose of this study was to devise a technique to evaluate the amount of muscle overlying the carpal tunnel. The hypothesis is that patients with carpal tunnel syndrome will have significantly more muscle overlying the carpal tunnel than individuals without carpal tunnel syndrome.
In the context of peripheral neuropathy, we will aim to elucidate correlates between sensory symptoms and: - Sensory nerve dysfunction. - Cutaneous small nerve fibre innervation density. - Psychological co-morbidity. - Circadian rhythm disturbance co-morbidity. - Functionality and Quality of life. - Patterns of human brain activity in a subset of patients that consent to participate in the FMRI (functional magnetic resonance imaging) component of PINS. 2. We will also collect blood samples in this phenotyped cohort of patients. These blood samples coupled with detailed phenotype data will investigate potential gene associations only in the development of painful neuropathy. 3. Knowledge gained from the study will be used to aid the further development of pain questionnaires, designed to detect patients with painful neuropathy. 4.Knowledge gained from the study will be invaluable in informing on-going investigations of painful peripheral neuropathy in animal models, both in our laboratory and others.
Investigators will recruit 20 healthy volunteers between the ages of 18 and 80, who have no history of carpal tunnel syndrome or wrist injury. Images will be captured twice, first with the 2D transducer and then with the 4D transducer and compared to images captured with the new 4D transducer, using the same movement data analysis protocols. Investigators will also assess the inter and intrarater reliability of the 4D transducer images, by using two different sonographers, both trained in the technique, measuring the same blinded images on separate occasions, at least two weeks apart. The overall goal of this project is to assess the reliability, or reproducibility, of measurements in normal subjects using a novel 4D ultrasonographic method to characterize the subsynovial connective tissue (SSCT) and detect motion between SSCT, median nerve and tendon motion for the evaluation and diagnosis of patients with disorders affecting the carpal tunnel, especially carpal tunnel syndrome (CTS).
Between 2008 and 2012 the investigators performed a single-center randomized double-blind placebo-controlled trial to assess the efficacy of local injection of two different doses of methylprednisolone (80 mg and 40 mg) in patients with carpal tunnel syndrome (CTS), aged 18 to 70 years, not previously treated with steroid injection. The primary outcomes were change in the CTS symptom severity score at 10 weeks and rate of carpal tunnel release surgery on the study hand at 1 year. In the trial 111 patients were randomized (37 in each of the 3 groups: 80 mg methylprednisolone, 40 mg methylprednisolone and placebo) and all completed the 1-year follow-up. The investiators plan an extended follow-up 5 to 7 years after injection.
Hypothesis: Manipulative treatment can relieve patients of discomfort and dysfunction and then be utilized as a cheap conservative management of CTS. Study design: Two-groups randomized single-blind interventional study.
The purpose of this research study is to investigate if magnet therapy is effective as an alternative therapy for CTS.
Carpal tunnel syndrome is the most expensive upper extremity work-related musculoskeletal disorder, impacting 10 million people annually and costing employers up to $113,695 per incident. There is currently no established method to detect this disorder prior to the onset of symptoms and nerve damage. Preliminary research suggests that sonography-a relatively inexpensive, widely available, increasingly portable technology-can provide a non-invasive and pain-free method of early detection that could reduce incidence, improve targeted interventions and ultimately reduce costs. The primary aims of this study are to establish predictive validity of a novel method for early detection using sonographic imaging and to identify task components of intensive functional hand activity associated with morphologic changes.
Carpal tunnel is an early manifestation of amyloidosis in a significant minority of patients. This specimen collection protocol will allow the investigators to screen patients with carpal tunnel syndrome for amyloidosis.
Purpose: To compare the outcome between sonography-guided steroid injection and direct steroid injection on carpal tunnel syndrome(CTS).
There is no golden universal standard for the diagnosis of Carpal Tunnel Syndrome (CTS). In this scenario, for a comparison of the effectiveness of the principal diagnostic tests CTS should determine how they affect the likelihood of disease through a clinical accuracy trial of good methodological quality in order to get answers to what is the best diagnostic strategy in clinical CTS practice. The paresthesia in nerve distribution territory median hands is the most common symptom in patients with CTS. The nuisance caused by paresthesia directly affects the quality of life of patients and impairs daily manual activities and sleep quality. To evaluate the remission of paresthesia is a major clinical criterion for improved STC being an expected relevant outcome for the patient. This study evaluated and compared the diagnostic accuracy of the ultrasonography (US) and electromyography (EMG), considering the postoperative status of remission of paresthesia as the reference standard in the diagnosis of CTS.
