Filter by:PEG is a fusogen, a type of chemical that aids in mediating cell fusion. PEG helps nerve cells recover neuronal continuity by removing plasmalemmal-bound water which opens the axonal ends on both sides of the injury. Opening axonal ends permits the nerve ends to reconnect and begin regeneration. PEG has been tested on animal models extensively and in earthworm models has been shown to induce fusion rates in 80-100% of neuronal cells. In crushed or severed mammalian sciatic nerves PEG has enhanced neuronal continuity to baseline functioning levels. Human applications for PEG have been tested by Bamba and colleagues in a case series with encouraging results. No studies, to our knowledge, have prospectively examined the use of PEG in peripheral nerve injuries. We propose a placebo controlled, double-blinded randomized controlled trial to test the hypothesis that local PEG administration can enhance sensory nerve regeneration following digital nerve transection compared to surgery 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 patients at our Prosthetics and Orthotics Outpatient Clinic who have had an ankle-foot orthosis for at least one year will fill in the Activities-Specific Balance Confidence Scale (ABC Scale) for wearing the orthosis and for not wearing the orthosis. They will also answer a mini survey about falls in order to determine whether they have fallen within the last 6 months.
The purpose of this study is to assess the safety of autologous human Schwann cell (ahSC) augmentation of nerve autograft repair in participants with severe peripheral nerve injury (PNI). For humans with acute severe PNI, the hypothesis is that augmentation of nerve autograft repair with ahSCs can potentially enhance axonal regeneration and myelin repair and thus improve functional recovery.
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.
This study is a prospective, multi-center, proof of principle, phase I human safety study evaluating the sequential treatments of the Avance Nerve Graft, a commercially available decellularized processed peripheral nerve allograft, with autologous Bone Marrow Aspirate Concentrate (BMAC), a source of stem cells, for the repair of peripheral nerve injuries up to 7 cm in length. The purpose of this study is to establish a knowledge product, evaluating the safety profile of the Avance Nerve Graft, followed by the application of BMAC to support further investment into the promising area of using stem cells in conjunction with scaffolds.
This Registry study will prospectively evaluate the long-term effectiveness, safety, and tolerability of the StimRouter Neuromodulation System, along with evaluating the technical performance of StimRouter, surgical outcomes, health-related quality of life, concomitant medical use, and subject's impression of improvement.
The objective of the study is to preliminarily evaluate the clinical safety and effectiveness of the bionic nerve scaffold with longitudinally oriented microchannels. 10 patients with peripheral sensory nerve defects will be involved and divided into 2 groups: the experimental group is treated with the nerve scaffold, and the control group without that. Then follow the cases up and draw conclusion according to the results of observation and examination.
The goal of this study is to ascertain the feasibility and safety of the procedure using SilkBridge - a biocompatible silk fibroin-based scaffold - for the regeneration of sensory nerve fibres and follow it up together with the reinnervation of the target organs (sensory receptors in the skin).
This study adopts a strategy that has arisen from basic neuroscience research on facilitating adaptive brain plasticity and applies this to rehabilitation to improve functional recovery in peripheral nervous system injuries (including hand transplantation, hand replantation, and surgically repaired upper extremity nerve injuries). The technique involves combining behavioral training with transcranial direct current stimulation (tDCS)-a non-invasive form of brain stimulation capable of facilitating adaptive changes in brain organization.
