The brainstem dorsal column nuclei (DCN) play a role in early processing of somatosensory information arising from a variety of functionally distinct peripheral structures, before being transmitted to the cortex via the thalamus. To improve our understanding of how sensory information is represented by the DCN, we characterised and mapped low- (<200 Hz) and high-frequency (550-3300 Hz) components of nerve-evoked DCN surface potentials. DCN surface potentials were evoked by electrical stimulation of the left and right nerves innervating cutaneous (sural nerve), or a mix of cutaneous and deep structures (peroneal nerve), in 8 week-old urethane anaesthetised male Wistar rats...

Sit-to-stand is a fundamental movement of human being for performing mobility and independent activity. However, Stroke people symptoms experience difficulty in conducting the sit-to-stand due to paralysis and especially ankle spasticity. Recently, transcutaneouselectrical- stimulation (TENS) is used to reduce pain but also to manage spasticity. The purpose of this study was to determine (1) whether TENS would lead to ankle spasticity reduction and (2) whether sit-to-stand training combined with TENS would improve spasticity, muscle strength and balance ability in stroke patients...

INTRODUCTION: Coir work, in a large number of people involves mechanically rolling the coconut fibers into coir which is later subjected to various processes. The primary work is done as a cottage industry specially by women in the sitting posture for several hours. This study reports evidence of median and common peroneal neuropathy electrophysiologically in people who had been engaged in this job for several years. This study was initiated to establish the possible relationship between coir work and symptomatic neuropathies which was seen in that region with all investigations "for other causes not" contributing to the etiological diagnosis...

Looking closely at an Argentine dream interpretation column published in a popular women's magazine from 1948 to 1951, this article examines the role of the dream image in shaping psychoanalytic discourse on femininity and national identity. The column, 'Psychoanalysis Will Help You,' emerged during Juan Domingo Perón's first presidency, featuring verbal interpretations written under the pen name 'Richard Rest,' as well as surreal photomontages by Grete Stern, a German-born, Bauhaus-trained photographer living in exile since 1936...

BACKGROUND: Side-to-side (STS) neurorrhaphy can be performed distally to ensure timely end-organ innervation. It leaves the distal end of the injured nerve intact for further reconstruction. Despite encouraging clinical results, only few experimental studies have been published to enhance the regeneration results of the procedure. We examined the influence of different size epineural windows and degree of axonal injury of STS repair on nerve regeneration and donor nerve morbidity. METHODS: Three clinically relevant repair techniques of the transected common peroneal nerve (CPN) were compared...

Vascularized free fibula transfer remains the gold standard for reconstruction of large segmental diaphyseal defects of the upper extremity. In the pediatric patient, before skeletal maturity, free fibula transfer with the fibular head provides an active physis for growth and an articular interface for glenohumeral joint reconstruction. Clinical and cadaveric studies have demonstrated that the vascular supply to the fibular head originates, in most cases, from the anterior tibial system. However, anatomical variation exists, and we report a case in which a vascularized fibula autograft including the physis was transferred on the peroneal artery in a 5-year-old patient with Ewing's sarcoma...

Introduction: Muscle sympathetic nerve activity (MSNA) may play a role in insulin resistance in obesity. However, the direction and nature of the relationship between MSNA and insulin resistance in obesity remain unclear. We hypothesized that resting MSNA would correlate inversely with both muscle and liver insulin sensitivity and that it would be higher in insulin-resistant vs. insulin-sensitive subjects. Materials and methods: Forty-five non-diabetic obese subjects were studied. As no significant relationships were found in women, the data presented in on 22 men aged 48 ± 12 years...

Cutaneous reflexes are important for rapidly responding to perturbations, correcting limb trajectory and strengthening support. During locomotion, they are modulated by phase to generate functionally appropriate responses. The goal of the present study was to determine if cutaneous reflexes and their phase-dependent modulation are altered with increasing speed and whether this is accomplished at a spinal level. Four adult cats that recovered stable hindlimb locomotion following spinal transection were implanted with electrodes to chronically record hindlimb muscle activity and to electrically stimulate the superficial peroneal nerve to evoke cutaneous reflexes...

Peroneal nerve injuries have been reported in association with various causes around the knee such as traumatic varus injury, traumatic dislocation, upper tibial osteotomy, knee arthroscopy and total knee arthroplasty. Two instances of varus arthritic knee associated with a peroneal nerve palsy have been reported so far. One presented with gradual onset peroneal nerve palsy that recovered with time and the other with sudden onset peroneal nerve palsy that did not recover. We describe the case of a 63-year-old man who presented with a symptomatic varus arthritic knee and sudden onset peroneal nerve palsy with synovial cysts over the lateral aspect of the knee...

In the current research, to find if the combination of chitosan nerve conduits seeded with autologous bone marrow mononuclear cells (BM-MNCs) can be used to bridge 30 mm long peroneal nerve defects in goats, 15 animals were separated into BM-MNC group (n = 5), vehicle group (n = 5), and autologous nerve graft group (n = 5). 12 months after the surgery, animals were evaluated by behavioral observation, magnetic resonance imaging tests, histomorphological and electrophysiological analysis. Results revealed that animals in BM-MNC group and autologous nerve graft group achieved fine functional recovery; magnetic resonance imaging tests and histomorphometry analysis showed that the nerve defect was bridged by myelinated nerve axons in those animals...

Schwannomas are benign neurogenic tumors of peripheral nerves that originate from neural sheath. The aim of this case report is to bring to mind the schwannoma in the patient with knee pain. A 39-year-old woman presented with a complaint of knee pain of three months history. After surgical intervention, the patient's complaints completely disappeared in the post-operative period. This should come to mind in the differential diagnosis of knee pain.
