BACKGROUND: Peripheral nerve injury causes physiological changes in primary afferent neurons. Neuropathic pain associated with peripheral nerve injuries may reflect changes in the excitability of the nervous system, including the spinothalamic tract. Current alternative medical research indicates that acupuncture stimulation has analgesic effects in various pain symptoms. However, activation changes in the somatosensory cortex of the brain by acupuncture stimulation remain poorly understood...

A constant coordination between the left and right leg is required to maintain stability during human locomotion, especially in a variable environment. The neural mechanisms underlying this interlimb coordination are not yet known. In animals, interneurons located within the spinal cord allow direct communication between the two sides without the need for the involvement of higher centers. These may also exist in humans since sensory feedback elicited by tibial nerve stimulation on one side (ipsilateral) can affect the muscles activation in the opposite side (contralateral), provoking short-latency crossed responses (SLCRs)...

Weidong Tong, Li Wang
The prevalence of chronic constipation is about 16% in adults, and increases with age, especially after 60 years old. Usually, surgical intervention is recommended to patients with long standing intractable constipation, who have undergone various conservative therapies. Lots of surgical procedures have been reported for different kinds of constipation, including slow transit, outlet obstruction, etc. For slow transit constipation, total or subtotal colectomy is commonly used. Merely for the internal rectal prolapse, at least 10 procedures are commonly adopted in clinic...

This study investigated the role of γ-aminobutyric acid subtype B (GABAB) receptors in tibial and pudendal neuromodulation of bladder overactivity induced by intravesical administration of dilute (0.5%) acetic acid (AA) in α-chloralose anesthetized cats. To inhibit bladder overactivity, tibial or pudendal nerve stimulation (TNS or PNS) was applied at 5 Hz and 2 or 4 times threshold (T) intensity for inducing toe or anal sphincter twitch. TNS at 2T or 4T intensity significantly (p<0.05) increased the bladder capacity to 173...

The role of cannabinoid type 1 (CB1) receptors in tibial and pudendal neuromodulation of bladder overactivity induced by intravesical infusion of 0.5% acetic acid (AA) was determined in α-chloralose anesthetized cats. AA irritation significantly (p<0.01) reduced bladder capacity to 36.6±4.8% of saline control capacity. Tibial nerve stimulation (TNS) at 2 or 4 times threshold (T) intensity for inducing toe movement inhibited bladder overactivity and significantly (p<0.01) increased bladder capacity to 69...

BACKGROUND: Current therapeutic guidelines for the treatment of chronic anal fissure establish a medical approach as the first step. Glyceryl trinitrate ointment is the most popular of the available topical treatments in Spain but it is associated with the appearance of headache. OBJECTIVE: The purpose of this study was to compare the compliance rate among patients receiving glyceryl trinitrate treatment for chronic anal fissure with that among patients receiving percutaneous posterior tibial nerve stimulation...

BACKGROUND AND OBJECTIVES: Ultrasound-guided subsartorial saphenous nerve block is commonly used to provide complete surgical anesthesia of the foot and ankle in combination with a popliteal sciatic nerve block. However, in part owing to its small caliber and absence of a prominent vascular landmark in the subsartorial plane distal to the adductor canal, the saphenous nerve is more difficult to reliably block than the sciatic nerve in the popliteal fossa. Although the saphenous nerve is a sensory nerve only, neurostimulation can be used to elicit a "tapping" sensation on the anteromedial aspect of the lower leg extending toward the medial malleolus...

BACKGROUND: Reports on alterations in somatic neural functions due to non-diabetic obesity, a major risk factor for diabetes, are few and still a matter of debate. Nevertheless, to our knowledge, reports lack any comments on the type of somatic nerve fibers affected in non-diabetic obesity. Therefore, this study aimed to find out the alteration in somatic neural functions in non-diabetic obese persons if any. METHODS: The study was conducted on 30 adult non-diabetic obese persons (mean age 32...

OBJECTIVE: Implant-driven tibial nerve stimulation therapy is an effective technique for treating overactive bladder. However, the monopolar lead design in the currently available implantable devices pose long-term therapeutic challenges in terms of efficiently and selectively delivering electrical pulses to the target. Hence, the purpose of this study was to (1) characterize the tibial nerve (TN) activation properties using a multi-contact implantable system and (2) evaluate the long-term stability of using such a neural interface in a preclinical model...

Following injury, primary sensory neurons undergo changes that drive central sensitization and contribute to the maintenance of persistent hypersensitivity. NR2B expression in the dorsal root ganglia (DRG) has not been previously examined in neuropathic pain models. Here, we investigated if changes in NR2B expression within the DRG are associated with hypersensitivities that result from peripheral nerve injuries. This was done by comparing the NR2B expression in the DRG derived from two modalities of the spared nerve injury (SNI) model, since each variant produces different neuropathic pain phenotypes...

AIMS: To determine the spinal segmental afferent contributions to tibial and pudendal inhibition of bladder overactivity. METHODS: Intravesical infusion of 0.5% acetic acid was used to irritate the bladder and induce bladder overactivity in anesthetized cats. Tibial or pudendal nerve stimulation was used to suppress the bladder overactivity and increase bladder capacity during cystometry. L5-S3 dorsal roots ipsilateral to the stimulation were exposed by a laminectomy and transected sequentially during the experiments to determine the role of individual dorsal roots in tibial or pudendal neuromodulation...

INTRODUCTION: Lumbar spinal stenosis (LSS) typically presents with neurogenic intermittent claudication (NIC). The aim is to investigate cauda equina conduction time (CECT) in patients with NIC caused by LSS and its relationship with age and body height in normal subjects. METHODS: The study included 172 normal subjects (mean age 44.1 ± 16.6 years; mean height 163.7 ± 8.9 cm). (Group C) 47 patients (mean age 71.3 ± 8.7 years; mean height 158.8 ± 11.2 cm) underwent surgery due to NIC in cauda equina type for LSS...

The insular cortex (IC) is a pain-related brain region that receives various types of sensory input and processes the emotional aspects of pain. The present study was conducted to investigate spatiotemporal patterns related to neuroplastic changes in the IC after nerve injury using voltage-sensitive dye imaging. The tibial and sural nerves of rats were injured under pentobarbital anesthesia. To observe optical signals in the IC, rats were re-anesthetized with urethane 7days after injury, and a craniectomy was performed to allow for optical imaging...

H-reflex depression (diminution of amplitude after a conditioning stimulus) is mediated presynaptically and therefore can help distinguish central versus peripheral mechanisms of fatigue. We examined the effects of a dynamic exercise protocol on H-reflex depression using two conditioning methods: homonymous conditioning (paired-pulse tibial nerve stimulation); and heteronymous conditioning (common peroneal nerve stimulation). Ten subjects performed dynamic contractions of the soleus muscle through 30° ankle range of motion...

OBJECTIVE This study is a retrospective case series involving C1-2 spinal cord stimulation in patients with complex regional pain syndrome (CRPS) under general endotracheal anesthesia. Currently, C1-2 paddle lead placement is an accepted practice, which provides effective cervical stimulation to ameliorate upper-extremity and sometimes lower-extremity symptoms experienced by patients with CRPS. However, this technique must be performed under general endotracheal anesthesia rather than in an awake or semiconscious state due to intraoperative safety concerns and patient comfort...
