Active clinical trials for "Carpal Tunnel Syndrome"

This is a study of the effects of fast paced assembly line work on women. We are studying problems women in poultry processing have with their muscles, tendons, and nerves as well as acute injuries they have in the workplace. We are also studying how their work affects the quality of their lives.

The purpose of this study is to collect data on the clinical and functional outcomes of surgical management for recurrent carpal tunnel syndrome (CTS) using flexor tenosynovectomy. It is hypothesized that the outcomes of patients undergoing flexor tenosynovectomy for recurrent CTS will compare favorably to published data regarding alternative types of surgeries for the same condition.

The goal of the Carpal Tunnel Release Using Ultrasound registry (CiTRUS Registry) is to collect experience information from patients scheduled to undergo carpal tunnel release surgery with either the SX-One MicroKnife® with ultrasound guidance or the traditional mini-open technique without US guidance.

Pain reduction effects of the median nerve neural mobilization technique (a physiotherapy treatment) will be compared to those produced by a pharmaceutical treatment and the absence of treatment, in subjects who suffer carpal tunnel syndrome.

In the present investigation the pain reduction effect of an oral ibuprofen treatment will be compared to those produced by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.

In the present investigation the pain reduction effects of Gabapentin will be compared to those produced by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.

In the present investigation the pain reduction effects of a physiotherapy technique will be compared to those produced by two different pharmaceutical treatments and also by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.

In the present investigation the pain reduction effects of a physical therapy technique will be compared to those produced by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.

Title Staged Bilateral Carpal Tunnel Release: Which Side Hurts More? Primary null hypothesis Patients undergoing staged bilateral open Carpal Tunnel Release (CTR) have no difference in overall pain intensity of pain between sides. Secondary null hypotheses There is no correlation in overall pain intensity after open CTR surgery and distal sensory latency, distal motor latency, electromyography (EMG), demographics, occupation, avocation, relevant comorbidities, dominance, left vs. right, Pain Self-Efficacy, Patient Reported Outcomes Measurement Information System (PROMIS) Upper Extremity or PROMIS depression when both surgeries are performed within 6 months. There is no difference in satisfaction with treatment at the time of suture removal after the first and second open CTR surgery when both are performed within 6 months.. IRB: 2009-p-001-019 ClinicalTrials.gov: Not mandatory, (b/o observational) Authors: Drijkoningen, Braun, Ring Journal: To be discussed Design: Prospective cohort study Background Many hand surgeons note that patients undergoing staged bilateral open carpal tunnel release often experience more pain with the second side. The investigator felt this was an easily testable hypothesis worthy of study. Subjects Eligibility: Inclusion: Age 18 or older Idiopathic carpal tunnel syndrome No prior surgery for carpal tunnel syndrome Exclude: Pregnant women Not fluent in English Response Variables: 11-point ordinal measure of overall pain intensity during and after surgery measured at the time of suture removal. 11-point ordinal measure of satisfaction with treatment PROMIS upper extremity Explanatory Variables: Distal Sensory Latency (DSL) Distal Motor Latency (DML) EMG changes Demographics: age, sex, race, occupation, avocation Time limit between two surgeries < 6 months Relevant comorbidities: Trapeziometacarpal (TMC) arthrosis, ulnar neuropathy, trigger finger Involved hand (Dominance, Side) First side vs. second side surgery PROMIS Pain Interference Computer Adaptive Testing (CAT) Pain Self Efficacy Questionnaire (PSEQ-2) PROMIS Depression Methods The investigator and study staff will invite all adult patients (age 18 and older) presenting to the Orthopaedic Hand and Upper Extremity Service Department at Massachusetts General Hospital (MGH) with bilateral carpal tunnel syndrome planning staged bilateral carpal tunnel release. Analysis Power analysis An a priori power analysis for matched pairs was performed. To detect the difference between two dependent means an effect size of 0.5 at alpha of 0.05 and 80% power, a total sample size of 34 patients is needed.As the investigator expects to have patients who will be lost to follow-up the investigators will count 10% extra, a total of 38 patients will be needed. Univariate analysis: Variables will be presented with frequencies and percentages for categorical variables and as mean with standard deviation or median with interquartile range for respectively normal or non-normal distributed continuous variables. Normality of continuous distributed variables will be tested a paired T-Test. Bivariate and multivariable analysis will be performed and subsequently all variables with a probability < 0.10 in bivariate analysis will be inserted in a backward, stepwise, multivariable linear regression analysis to assess their ability to explain variation in outcome. The 11 point Likert Pain scale score is considered significant when there is a difference of more than 1.4 points (2.8 SD*0.5 effect size)on a scale from 1-10.[9]

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).
