Active clinical trials for "Peripheral Nerve Injuries"

The purpose of this study is to evaluate the role of single dose 4-aminopyridine (4-AP) on the diagnosis of severing vs non-severing nerve injury after peripheral nerve traction and/or crush injury. The investigational treatment will be used to test the hypothesis that 4-aminopyridine can speed the determination of nerve continuity after peripheral nerve traction and/or crush injuries allowing the identification of incomplete injuries earlier than standard electrodiagnostic (EDX) and clinical assessment. Participants will be randomized to one of two groups to determine the order of treatment they receive (drug and placebo vs placebo and drug). Participants will undergo baseline testing for nerve assessment, receive either drug or placebo based on randomization and undergo hourly sensory and motor evaluation, EDX testing and serum 4AP levels for three hours after dosing. Participants will then repeat this with the crossover arm.

This is a prospective, multi-center, observational registry designed to evaluate two of Integra's collagen nerve gap repair products (NeuraGen® Nerve Guide and NeuraGen® 3D Nerve Guide Matrix). This registry will collect data on the outcome measures throughout the follow-up period for each patient. Data will be collected per standard of care.

After nerve injury and facial palsy, many patients have permanent muscle and sensory dysfunction. Electrical stimulation (ES) of injured nerves may speed up axon growth and improve recovery. This study will assess if ES accelerates motor axon regeneration and improves muscle recovery in patients undergoing two-staged facial reanimation for facial palsy. This study of ES in these patients will investigate: i) nerve regeneration over long distances; ii) direct evidence of changes in nerve regeneration with nerve samples from the second procedure; and iii) changes in functional outcomes in a patient population with much less variability. Our study will provide evidence about the effect of ES in improving outcomes in patients with nerve injuries.

The purpose of this clinical investigation is to confirm the medium- and long-term safety and performance of the chitosan-based nerve guide (Reaxon® Nerve Guide) in comparison to an autologous nerve graft to bridge nerve defects in the finger.

The purpose of the study is to determine the efficacy of etoricoxib on pain patients. The investigators assume that patients with neuropathic pain will have greater pain relief then patients on placebo.

The primary purpose is to study the predictive value of preserved nociceptors and large afferent fibers and dynamic mechanical allodynia on the effect of lidocaine patch. The primary outcome measure is the predictive role for these three measures for obtaining a response to lidocaine. A responder is defined as a person with at least a 2-point pain reduction to lidocaine (change in median pain intensity (measured on a 10 point numeric rating scale) of pain from the baseline week to the last week of lidocaine treatment). Secondary effect variable will be efficacy of lidocaine on pain reduction (baseline week versus last week of each treatment) and pain relief (complete, good, moderate, slight, none, or worse) for spontaneous and evoked pain, and effect on ongoing pain, brush evoked allodynia, cold and warm allodynia, and pinprick hyperalgesia evaluated on each visit.

This study will be a double-blind, placebo-controlled, parallel group study. After enrolment and initial assessments, subjects will receive oral GW856553 7.5 milligram (mg) twice daily (BID) or matching placebo for 28 days in a 1:1 ratio. Sufficient numbers of subjects will be recruited to obtain 142 evaluable subjects. This is a double-blind, randomized, placebo-controlled, parallel group study. Subjects will undertake a screening period which may last up to approximately 3 weeks, followed by a baseline period of 1 week, a randomized treatment period of 4 weeks and a follow-up period of approximately 2 weeks. This is a multi-centre, double-blind, randomized, placebo-controlled study in subjects who have at least moderate intensity of neuropathic pain resulting from peripheral nerve injury due to trauma or surgery. It will investigate the efficacy, safety and tolerability of GW856553 over 28 days of treatment. Approximately 158 subjects will be randomized to ensure 142 evaluable subjects. Randomization ratio will be 1:1 for placebo or GW856553 respectively. The dose of GW856553 will be 7.5 mg BID.

This study evaluated the effects of an integrated program of touch-observation and task-based mirror therapy on sensorimotor function in nerve injury patients. Before the return of protective sense (Value of Semmes-Weinstein monofilament test > 4.31), half of the participants received 15 minutes of mirror therapy program, followed by 20 minutes of regular hand therapy and 20 minutes of physiotherapy.While the other half received 15 minutes protective sensory reeducation programs, 20 minutes of regular hand therapy and 20 minutes of physiotherapy in each treatment session. Once the patients had regained the protective sense (Value of Semmes-Weinstein monofilament test < 4.31), the discriminative sensory reeducation program was started for the participants in both groups. The hypothesis was that using the mirror therapy for sensorimotor reeducation in the early phase after nerve repair would yield better results with regard to the returning of sensation, sensorimotor control ability and hand function than using a classical reeducation program alone.

The outcome of peripheral nerve injury is related to age, level of injury, the injured nerve, the severity of injury, and the timing and the type of surgery interventions. In addition, high-level peripheral nerve injury would not full recovery, and the prognosis is determined by the nerve regeneration. Conventional physical therapy includes electrical stimulation for denervated muscles, and soft tissue massage, joint range of motion exercises to maintain the flexibility of the affected joint, muscle or connected tissues. However, the nerve regeneration takes several months in high-level median, ulnar or radial nerve injury. Prolonged median or ulnar nerves injury may interfere intrinsic muscular function, and radial nerve injury causes drop hand. Earlier nerve regeneration or motor training is essential for the patients to return to normal life and increase their quality of life

The purpose of this trial is to determine if the effect of oxcarbazepine on chronic peripheral nerve pain depends on the supposed mechanism of the pain, ie. if oxcarbazepine mainly relieve pain in patients with irritable nerves.
