The peripheral nervous system has the intrinsic capacity to regenerate axons into target tissues, and peripheral nerves severely damaged or transected can be reconstructed by microsurgical techniques. The aim of peripheral nerve surgery is to pave way for fast and most possible thorough functional recovery. However, full functional recovery is rarely seen and several reasons for this have alrea...

Hyperbaric oxygen has been successfully used on treatment of acute ischemic injuries involving soft tissues and chronic injuries. In nerve crush injuries, the mechanisms involved are very similar to those found in ischemic injuries. Consequently, it is logical to hypothesize that hyperbaric oxygen should improve nerve repair, which is a critical step on functional recovery. In the present study...

Infraorbital nerve (ION) transection in neonatal rats leads to disruption of whisker-specific neural patterns (barrelettes), conversion of functional synapses into silent synapses, and reactive gliosis in the brain stem trigeminal principal nucleus (PrV). Here we tested the hypothesis that neonatal peripheral nerve crush injuries permit better functional recovery of associated central nervous s...

Tendon transfers in birth brachial plexus palsy Many patients with birth brachial plexus palsy (BBPP) have good spontaneous recovery. This is because the injury is a low velocity injury compared to the adult palsy and hence the injury is mostly a stretch injury which has high potential to recover. Even if there is rupture of the roots the distance to bridge and to travel to the destination is c...

Effects of Epimedium extract and its constituent icariin on peripheral nerve repair were investigated in a crush injury rat model. Animals were divided into four groups: sham, control, Epimedium extract, and icariin groups. At postoperative weeks 1, 2, 4, and 8, nerve regeneration and functional recovery were evaluated by sciatic functional index (SFI), nerve electrophysiology, nerve pinch test...

OBJECTIVE To compare the outcome of muscle strength with manual muscle strength testing grip and pinch strength measurements and a dynamometer which allows for measurements of the intrinsic muscles of the hand in isolation (the Rotterdam Intrinsic Hand Myometer, RIHM). METHODS Thirty-four patients more than 2 years after ulnar and/or median nerve injury. Muscle strength was evaluated using ma...

Olfactory ensheathing cells (OECs) represent an interesting candidate for cell therapy and could be obtained from olfactory mucosa (OM-OECs) or olfactory bulbs (OB-OECs). Recent reports suggest that, depending on their origin, OECs display different functional properties. We show here the complementary and additive effects of co-transplanting OM-OECs and OB-OECs after lesion of a peripheral ner...

Recovery of behavioural and sensory function was examined following unilateral pedal nerve crush in Aplysia californica. Nerve crush that transected all axons connecting the tail to the central nervous system (CNS) eliminated the ipsilateral tail-evoked siphon reflex, whose sensory input travels in the crushed tail nerve (p9). The first reliable signs of recovery of this reflex were observed wi...

BACKGROUND AND AIM Curcumin at 100mg/kg has been shown to have a protective effect on crush nerve injury. However, it is unclear whether the protective effect of curcumin on nerve injury is dose dependent. The present study was designed to investigate such a possibility. METHODS The rats subjected to crush nerve injury were intraperitoneally administrated daily for 4 weeks with curcumin (50 m...
