17 Clinical Trials for Various Conditions
This pilot study aims to investigate the effects of nerve blocks in patients with diabetic peripheral neuropathy through a double-blinded, randomized trial involving 4 patients. Each participant will receive bilateral peripheral nerve blocks using either lidocaine or papaverine. Following randomization, each patient will receive one medication in one leg and the alternate medication in the contralateral leg. Researchers will measure parameters including motor strength, sensory function (two-point discrimination), arterial blood flow via Doppler ultrasound, and microvascular perfusion using near-infrared spectroscopy both prior to and following nerve block administration. This research seeks to explore potential diagnostic and therapeutic applications for peripheral nerve entrapment, a common yet challenging clinical condition.
The investigators are comparing two standard of care procedures which can be performed at the same time, or sequentially. The hypothesis being tested is whether simultaneous release of both the carpal Tunnel and the Pronator Teres results in a better outcome in terms of symptom relief and recurrence than Carpal Tunnel Release alone when signs and symptoms of both carpal tunnel and pronator Teres syndromes are present.
The UT Southwestern Medical Center at Dallas would like to give you information about a research study that is being done for patients with painful diabetic neuropathy and have not responded to medical treatment. Doctors from the departments of Internal Medicine, Physical Medicine and Rehabilitation, Neurology, Pain Management and Plastic Surgery are conducting a research study to examine the effects of nerve decompression on decreasing the pain associated with diabetic neuropathy and increasing the sensation at the bottom of the foot.
Nerve injury is a serious potential complication associated with the clinical use of exsanguinating tourniquets in surgery. Recently, a novel narrow tourniquet has been proposed, with the claim that it may cause less compression of the nerves. We performed an in vivo comparison of a standard wide tourniquet with the new, narrow tourniquet. Our study specifically looked at neurologic markers in the upper extremity.
This study is evaluating a new therapeutic use of electrical stimulation to promote nerve healing and improve functional recovery following surgical intervention for nerve compression. A single dose of the therapeutic stimulation is delivered as part of the surgical intervention to address compression of the ulnar nerve at the elbow.
Functional motor recovery distal to a peripheral nerve lesion is predicated upon time to reinnervation of the motor end plate and the number of regenerate axons that reach the target. Supercharged end-to-side (SETS) transfer of the anterior interosseous nerve to the motor fascicle of the ulnar nerve at the level of the distal forearm has been proposed as an adjunct procedure in severe cubital tunnel syndrome to augment motor recovery of the ulnar-innervated intrinsic muscles. Multiple Level IV Therapeutic studies and a systematic review of Level IV Therapeutic studies have reported favorable clinical and electrodiagnostic outcomes following SETS for cubital tunnel syndrome, with low rates of complications. However, in the absence of controls, it remains unclear what proportion of the observed intrinsic motor recovery is attributable to the SETS procedure. The objective of this randomized trial is to compare the results of ulnar nerve decompression with or without SETS for severe cubital tunnel syndrome.
The purpose of this study is to identify the issues that have greatest impact on QOL for patients with Charcot Marie Tooth (CMT) Disease. Patients who have -registered in the Inherited Neuropathies Consortium Contact Registry will be invited to participate.
The study will be a non-blinded two cohort design consisting only of symptomatic patients with CuTS or compressive peroneal neuropathy or in need of peroneal nerve decompression. The first cohort will be - patients with CuTS. Evaluation of each CuTS patient will include assessment by the treating surgeon and a certified hand therapist. Patients who have clinical examination and history consistent with a diagnosis of CuTS based on subjective and functional assessment outlined below will be consented to this study. The second cohort will be patients in need PND for compressive neuropathy of peroneal nerve. PND patients will be evaluated by clinical exam and have imaging with high resolution ultrasound or MRI negative for mass lesion.
This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
Carpal tunnel release is a well accepted treatment for median nerve compression at the wrist. With a prevalence of 50 per 1000, it is the most common compressive neuropathy. With a number of anatomic as well as systemic factors playing a role in the development of carpal tunnel syndrome, it is not surprising that there is a high incidence of bilaterality with this disease. Padua et al. reported that 87% of 266 consecutive cases had signs and symptoms of carpal tunnel syndrome in their contralateral hand. In patients who have bilateral carpal tunnel syndrome that has not responded to conservative treatment, surgical release is indicated. In such cases, a decision must be made whether to offer bilateral simultaneous surgical release or to stage the two affected hands to allow time to recover from each. The purpose of this study is to determine the differences in short term disability between having bilateral vs unilateral carpal tunnel release. With better understanding of the way in which patients are impaired, better recommendations may be made on which patients to indicate for simultaneous bilateral procedures and who would benefit from staging procedures, allowing the patient to recover from one hand prior to proceeding to surgery on the other hand.

An investigation of a new catheter and pressure monitor system that may help to prevent a complication called compartment syndrome from developing in an injured leg. Compartment syndrome occurs when too much fluid builds up in the muscles of the injured leg. This causes a lot of swelling and increases pressures within the leg that can cause permanent damage muscles and nerves in the leg.
The purpose of this study is to evaluate the analgesic efficacy and safety of the lidocaine patch 5% compared to placebo in patients with moderate to severe pain associated with carpal tunnel syndrome.
The purpose of this study is to test a physical therapy intervention for reducing pain in the low back and into the legs. With individuals over the age of 40 years, this pain may be associated to changes in back height from aging of the cushions between the back bones. When pain is caused from this, completion of different positions and rest periods have been shown to help reduce the pain, at least temporarily. This study will compare two such positions; 1)floating in deep warm water with weights attached to the ankles, to take the load off of the spine, 2)lying on their back with hip and knees flexed to a 90 degree angle. The height of each person will be measured before and after completion of each intervention using a specially designed measuring tool. Experimental hypothesis: 1. Subjects with low back and leg pain suggestive of nerve root compression syndrome will experience increase in spinal height when completing aquatic vertical suspension and/or land-based supine flexion. 2. Subjects with low back and leg pain suggestive of nerve root compression syndrome will experience greater increase in height, greater reduction of pain intensity and location when completing underwater vertical suspension as compared to supine land based flexion.
The purpose of this study was to examine the effect of prolonged sitting duration and three different sitting postures (erect, slumped, and slouched sitting postures) on spinal nerve root function by measuring the soleus (SOL) H-reflex amplitude. In addition, the pressure under the ischial tuberosities during the three sitting postures were assessed and correlated with the SOL H-reflex amplitude.
The goal of this study is to assess the efficacy of lidocaine basivertebral nerve block as intraprocedural anesthesia during vertebral augmentation procedures.
The primary objective of this study is to evaluate the safety and efficacy of nerve transfer surgery for restoring hand function as a therapy for patients with cervical spinal cord injury.
