Abstract
Yoga is considered a widely-used approach for health conservation and can be adopted as a treatment modality for a plethora of medical conditions, including neurological and psychological disorders. Hence, we reviewed relevant articles entailing various neurological and psychological disorders and gathered data on how yoga exerts positive impacts on patients with a diverse range of disorders, including its modulatory effects on brain bioelectrical activities, neurotransmitters, and synaptic plasticity. The role of yoga practice as an element of the treatment of several neuropsychological diseases was evaluated based on these findings.

Abstract
Carpal tunnel syndrome, ulnar neuropathy at the elbow, and peroneal neuropathy are the most common mononeuropathies; however, other individual nerves may also be injured by various processes. These uncommon mononeuropathies may be less readily diagnosed owing to unfamiliarity with the presentations and vague symptoms. Electrodiagnostic studies are essential in the evaluation of uncommon mononeuropathies and can assist in localization and prognostication. However, they can also be challenging; stimulation at the proximal sites is difficult and well-validated reference values are not available. This article reviews the electrodiagnostic assessment of several uncommon upper and lower extremities mononeuropathies.

Abstract
INTRODUCTION An isolated injury to the tibial division is rare among compressive sciatic neuropathy. To date, isolated injury to the tibial division of the sciatic nerve after self-massage of the gluteal muscle has not been reported. Here, we report a case of compressive sciatic neuropathy diagnosed after self-massage of the gluteal muscle using magnetic resonance image (MRI) and ultrasound images and its associated therapeutic process. PATIENT CONCERNS A 50-year-old woman presented right lower extremity pain for the past 7 days. DIAGNOSIS Electrophysiological findings were consistent with right tibial neuropathy proximal to the branch to hamstring muscles. However, T2-weighted MRI showed high signal intensity and swelling in the right sciatic nerves from the superior gemellus level to the quadratus femoris level. After considering both radiologic and electrophysiological findings, the patient was diagnosed with an isolated injury to the tibial division of the right sciatic nerve. INTERVENTIONS The patient agreed to an ultrasound-guided perineural steroid injection upon receiving detailed explanation of the procedure. OUTCOMES After the injection, there was significant improvement in pain. CONCLUSION Therefore, in making a diagnosis of sciatic neuropathy, it may be important to find the lesion via MRI than relying solely on the patient's history or electrophysiologic study.

Abstract
RATIONALE Sciatic neuropathy has various causes; however, cases in which a pressure ulcer led to sciatic neuropathy have not been reported to date. PATIENT CONCERNS A 33-year-old woman with no pre-existing mobility problems visited our department with the chief complaint of an extensive pressure ulcer and necrosis in her right buttock. She had a medical history of being bedridden for 2 days while in a coma due to a drug overdose 2 months previously. Physical examination revealed loss of sensation and foot drop in the right foot. DIAGNOSIS Physical examination, magnetic resonance imaging, and nerve conduction studies were conducted; the patient was diagnosed with a common peroneal branch injury of the right sciatic nerve. INTERVENTIONS The necrotic tissue was debrided and sciatic nerve decompression was performed, followed by frequent dressing changes. In addition, psychiatric treatment and physical therapy were performed simultaneously. OUTCOMES The pressure ulcer decreased in size and healed to some extent with granulation tissue. However, gait disorders, accompanied by symptoms of sciatic neuropathy, continued. The patient was transferred to the department of gastroenterology for the treatment of toxic hepatitis, which occurred during her inpatient treatment. LESSONS Physicians should be aware that sciatic neuropathy may occur during the treatment of patients with a pressure ulcer who exhibit no symptoms of paraplegia or quadriplegia. To prevent neuropathy, aggressive treatment of the pressure ulcer is necessary.

Abstract
We examined the effect of transplantation of allogenic adipose-derived stem cells (ADSCs) with properties of mesenchymal stem cells (MSCs) on posttraumatic sciatic nerve regeneration in rats. We suggested an approach to rat sciatic nerve reconstruction using the nerve from the other leg as a graft. The comparison was that of a critical 10 mm nerve defect repaired by means of autologous nerve grafting versus an identical lesion on the contralateral side. In this experimental model, the same animal acts simultaneously as a test model, and control. Regeneration of the left nerve was enhanced by the use of ADSCs, whereas the right nerve healed under natural conditions. Thus the effects of individual differences were excluded and a result closer to clinical practice obtained. We observed significant destructive changes in the sciatic nerve tissue after surgery which resulted in the formation of combined contractures in knee and ankle joints of both limbs and neurotrophic ulcers only on the right limb. The stimulation of regeneration by ADSCs increased the survival of spinal L5 ganglia neurons by 26.4%, improved sciatic nerve vascularization by 35.68% and increased the number of myelin fibers in the distal nerve by 41.87%. Moreover, we have demonstrated that S100, PMP2, and PMP22 gene expression levels are suppressed in response to trauma as compared to intact animals. We have shown that ADSC-based therapy contributes to significant improvement in the regeneration.

Abstract
Nerve injury is a common complication following intramuscular injection and the sciatic nerve is the most frequently affected nerve, especially in children, the elderly and underweight patients. The neurological presentation may range from minor transient pain to severe sensory disturbance and motor loss with poor recovery. Management of nerve injection injury includes drug treatment of pain, physiotherapy, use of assistive devices and surgical exploration. Early recognition of nerve injection injury and appropriate management are crucial in order to reduce neurological deficit and to maximize recovery. Sciatic nerve injection injury is a preventable event. Total avoidance of intramuscular injection is recommended if other administration routes can be used. If the injection has to be administered into the gluteal muscle, the ventrogluteal region (gluteal triangle) has a more favourable safety profile than the dorsogluteal region (the upper outer quadrant of the buttock).

Sciatic nerve injury related to hip replacement surgery: imaging detection by MR neurography despite susceptibility artifacts. PLoS One 2014; 9:e89154.

Abstract
Sciatic nerve palsy related to hip replacement surgery (HRS) is among the most common causes of sciatic neuropathies. The sciatic nerve may be injured by various different periprocedural mechanisms. The precise localization and extension of the nerve lesion, the determination of nerve continuity, lesion severity, and fascicular lesion distribution are essential for assessing the potential of spontaneous recovery and thereby avoiding delayed or inappropriate therapy. Adequate therapy is in many cases limited to conservative management, but in certain cases early surgical exploration and release of the nerve is indicated. Nerve-conduction-studies and electromyography are essential in the diagnosis of nerve injuries. In postsurgical nerve injuries, additional diagnostic imaging is important as well, in particular to detect or rule out direct mechanical compromise. Especially in the presence of metallic implants, commonly applied diagnostic imaging tests generally fail to adequately visualize nervous tissue. MRI has been deemed problematic due to implant-related artifacts after HRS. In this study, we describe for the first time the spectrum of imaging findings of Magnetic Resonance neurography (MRN) employing pulse sequences relatively insensitive to susceptibility artifacts (susceptibility insensitive MRN, siMRN) in a series of 9 patients with HRS procedure related sciatic nerve palsy. We were able to determine the localization and fascicular distribution of the sciatic nerve lesion in all 9 patients, which clearly showed on imaging predominant involvement of the peroneal more than the tibial division of the sciatic nerve. In 2 patients siMRN revealed direct mechanical compromise of the nerve by surgical material, and in one of these cases indication for surgical release of the sciatic nerve was based on siMRN. Thus, in selected cases of HRS related neuropathies, especially when surgical exploration of the nerve is considered, siMRN, with its potential to largely overcome implant related artifacts, is a useful diagnostic addition to nerve-conduction-studies and electromyography.

Abstract
Peripheral nerve entrapments are frequent. They usually appear in anatomical tunnels such as the carpal tunnel. Nerve compressions may be due to external pressure such as the fibular nerve at the fibular head. Malignant or benign tumors may also damage the nerve. For each nerve from the upper and lower limbs, detailed clinical, electrophysiological, imaging, and therapeutic aspects are described. In the upper limbs, carpal tunnel syndrome and ulnar neuropathy at the elbow are the most frequent manifestations; the radial nerve is less frequently involved. Other nerves may occasionally be damaged and these are described also. In the lower limbs, the fibular nerve is most frequently involved, usually at the fibular head by external compression. Other nerves may also be involved and are therefore described. The clinical and electrophysiological examination are very important for the diagnosis, but imaging is also of great use. Treatments available for each nerve disease are discussed.

Abstract
OBJECTIVE The sciatic nerve may normally exhibit mild T2 hyperintensity in MR neurography (MRN) images, rendering assessment of sciatic neuropathy difficult. The purpose of this case-control study was to evaluate whether a quantitative and qualitative analysis of the sciatic nerves and regional skeletal muscles increases the accuracy of MRN in detecting sciatic neuropathy. MATERIALS AND METHODS We retrospectively reviewed the MRN studies of the pelvis and thighs of 34 subjects (12 men and 22 women; mean [± SD] age, 50 ± 15 years), of which 17 had a final diagnosis of sciatic neuropathy according to electrodiagnostic or surgical confirmation, and 17 had no evidence of sciatic neuropathy and served as control subjects. On each side, the sciatic nerves were evaluated for signal intensity (SI), size, course, and fascicular shape, whereas the regional skeletal muscles were evaluated for edema, fatty replacement, and atrophy. In addition, the nerve-to-vessel SI ratio was registered for each side at the same time and 8 months later. RESULTS The sciatic nerves of the abnormal sides exhibited higher nerve-to-vessel SI ratios and higher incidences of T2 hyperintensity, enlargement, and abnormal fascicular shape compared to the nerves of the normal sides. The regional muscles of the abnormal sides demonstrated a higher grade of fatty infiltration and higher frequencies of edema and atrophy. A cutoff value of nerve-to-vessel SI ratio of 0.89 exhibited high sensitivity and specificity in predicting sciatic neuropathy. Calculation of the nerve-to-vessel SI ratio demonstrated excellent inter- and intraobserver reliability. CONCLUSION Both qualitative and quantitative criteria should be used to suggest the MRN diagnosis of sciatic neuropathy.

Abstract
Sciatic nerve traumatic damage very rarely occurs bilaterally. We describe the case of a 67-year-old woman who reported a bilateral traumatic lesion of the sciatic nerve during practice of yoga. Nerve conduction studies showed a bilateral sciatic nerve neuropathy, mostly affecting the peroneal component. Lumbar plexus MRI documented regular anatomical features of the main principal nerve roots with bilateral T2 signal alteration of roots L4, L5 and S1 that extended into the sciatic nerves showing both increase in size, probably related to chronic injury of nerves, and an alteration in diffusion signal that suggested a recent acute overlapped process.

Abstract
BACKGROUND Nurses are required to perform gluteal intramuscular (IM) injections in practice. There are dangers associated with erroneous performance of this task, particularly with dorsogluteal injections. Knowledge regarding safe injection practice is therefore vital for nursing students. METHOD Fifty-eight second year students at a New Zealand Nursing School were given schematic drawings of the posterior and lateral aspects of the gluteal region. They were asked to mark and justify the safest location for gluteal IM injections. RESULTS Fifty-seven students marked the dorsal schematic and one the lateral, with 38 (66.7%) marking in the upper outer quadrant (UOQ). Twenty indicating the UOQ (52.6%) wrote 'sciatic' or 'nerve' in justifying their location. Nineteen (33.3%) marked a location outside the UOQ; nine (47.4%) of these mentioned 'sciatic' or 'nerve' as reasons for injection safety. Overall, 50% of students mentioned 'sciatic' or 'nerve' in justifying the safety of their chosen injection location. CONCLUSION Results suggest some second year nursing students do not understand safe gluteal IM injection locations and rationale. Current teaching practices and IM injection techniques could be revisited to prepare students more effectively; this may help prevent pathologies arising from this procedure.

Abstract
We report on magnetic resonance neurography (MRN) as a supplementary diagnostic tool in sciatic nerve injection injury. The object of the study was to test if T2-weighted (w) contrast within the sciatic nerve serves as an objective criterion for sciatic injection injury. Three patients presented with acute sensory and/or motor complaints in the distribution of the sciatic nerve after dorsogluteal injection and underwent MRN covering gluteal, thigh and knee levels. Native and contrast-enhanced T1-w images were employed to identify the tibial and peroneal division of the sciatic nerve while T2-w images with fat suppression allowed visualization of the site and extent of the nerve lesion. MRN in the two patients with clinically severe sensory and motor impairment correctly depicted sciatic injury: continuity of the T2-w lesion within the nerve at the lesion site and distal to it corresponded well to severe injury confirmed by NCS/EMG as axonotmetic or neurotmetic. Topography of the T2-w lesion on cross-section corresponded to predominant peroneal involvement; moreover, associated denervation patterns of distal target muscles were revealed. One of these patients completely recovered with concomitant complete regression of MRN abnormalities on follow-up. The third patient experienced transient sensory and mild motor impairment with complete recovery after 2 weeks. In this patient, T2-w signal within the nerve and distal target muscles remained normal indicating only mild, non-axonal nerve affliction. Our case series shows that MRN can be very useful in precisely determining the site of sciatic injection injury and may provide diagnostic criteria for the assessment of lesion severity and recovery.

Abstract
High-resolution MR imaging of peripheral nerves is becoming more common and practical with the increasing availability of 3T magnets. There are multiple reports of MR imaging of peripheral nerves in compression and entrapment neuropathies. However, there is a relative paucity of literature on MRN appearance of diffuse peripheral nerve lesions. We attempted to highlight the salient imaging features of myriad diffuse peripheral nerve disorders and imaging techniques for MRN. Using clinical and pathologically proved relevant examples, we present the MRN appearance of various types of diffuse peripheral nerve lesions, such as traumatic, inflammatory, infectious, hereditary, radiation-induced, neoplastic, and tumor variants.

Abstract
BACKGROUND Post injection sciatic nerve injury is a common cause of sciatic nerve mononeuropathy in the developing world largely due to inadequate health care facilites in the rural regions. OBJECTIVE The study was conducted to analyse the pattern of this nerve lesion in clinical and electrophysiological parameters and also to study the outcome in a conservatively treated cohort. MATERIALS AND METHODS One hundred and six patients who underwent evaluation at our laboratory from 2000 to 2006 for post injection sciatic neuropathy formed the study population. Twenty two of these were followed up (mean 6.6 months) for the outcome. RESULTS In the cases with full data, common peroneal division of the sciatic nerve was affected alone or predominantly. On follow up, 72% cases showed little or partial recovery. Thirty two percent patients had residual trophic changes and causalgia at their last visit. CONCLUSION The majority of cases of postinjection sciatic nerve injury have poor prognosis on conservative treatment.

Abstract
OBJECTIVE To illustrate magnetic resonance neurography findings of severe sciatic injury and muscle denervation related to deep gluteal endometriosis at the sciatic notch. DESIGN Case report. SETTING Academic teaching hospital. PATIENT(S) A 39-year-old woman with a 4-year history of sciatica related to the menstrual cycle. INTERVENTION(S) Surgical exploration of the sciatic notch for diagnostic confirmation, external neurolysis of the sciatic nerve, and eventual pharmacologic treatment. MAIN OUTCOME MEASURE(S) Magnetic resonance neurography imaging revealed severe neuropathic injury and muscle denervation related to a deep infiltrative endometriotic focus at the sciatic notch, which was confirmed histologically on surgical exploration. Detailed electrodiagnostic and clinical neurologic examinations at initial presentation and during follow-up were obtained for further assessment of nerve degeneration, muscle denervation, and clinical recovery. RESULT(S) Initial gynecologic and eventual laparoscopic evaluation on persisting complaints were without pathological findings. When a progressive weakness of the leg was noted, magnetic resonance neurography revealed a severe axonal damage to the sciatic nerve and denervation of distal target muscles related to a diffuse infiltrative lesion at the sciatic notch. On surgical exploration, extragenital endometriosis was confirmed histologically. Considerable improvement in pain and strength occurred after pharmacologic therapy with a GnRH analogue. CONCLUSION(S) This is the first report to describe imaging findings of magnetic resonance neurography in severe neuropathic injury of the sciatic nerve and subsequent muscle denervation related to a deep infiltrative gluteal endometriotic focus.

Abstract
The authors report an isolated case of right sacrospinous ligament ossification causing sciatic pain because of compression of the proximal sciatic nerve. The initial conservative treatment of injections in the conflict zone and the intervertebral joints was insufficient. Surgical exploration was undertaken via a posterior approach, demonstrating the conflict between the nerve and the ossified ligament. Resection of the ossified ligament eliminated the symptoms at the cost of transitory buttock hypesthesia. The anatomic and pathologic exam identified simple osseous metaplasia. Lumbar-pelvic coxometry analysis showed sagittalization of the acetabular roofs, excessive bilateral femoral torsion, and a step-off attenuation at the anterior cervicocephalic junction (low anterior cervico-cephalic femoral offset). In addition, reduced lumbar lordosis and accentuated sacral slope were noted, factors that could be related to modifications in the static balance of the lumbar-pelvic complex. This imbalance could be correlated to an increase in the forces applied to the pelvic ligament layers. The etiological hypothesis retained was that this osseous metaplasia was a reaction to excessive stresses on the sacrospinous ligament.

Abstract
Following proximal peripheral nerve injury, motor recovery is often poor due to prolonged muscle denervation and loss of regenerative potential. The transfer of a sensory nerve to denervated muscle results in improved functional recovery in experimental models. The authors here report the first clinical case of sensory protection. Following a total hip arthroplasty, this patient experienced a complete sciatic nerve palsy with no recovery at 3 months postsurgery and profound denervation confirmed electrodiagnostically. He underwent simultaneous neurolysis of the sciatic nerve and saphenous nerve transfers to the tibialis anterior branch of the peroneal nerve and gastrocnemius branch from the tibial nerve. He noted an early proprioceptive response. Electromyography demonstrated initially selective amelioration of denervation potentials followed by improved motor recovery in sensory protected muscles only. The patient reported clinically significant functional improvements in activities of daily living. The authors hypothesize that the presence of a sensory nerve during muscle denervation can improve functional motor recovery.

Abstract
A 10-year-old boy who had been treated for acute lymphoblastic leukemia presented with persistent numbness of the left big toe and progressive pain of the ipsilateral lower leg. He had received allogeneic bone marrow transplantation 3 months after a testicular relapse. He was in hematologic remission at admission but as progressive swelling of his left leg continued, bone marrow relapse developed. A muscle biopsy revealed leukemic infiltrates in the surrounding muscles of the left sciatic nerve, and swelling of the nerve was found on a magnetic resonance imaging scan. His symptoms/signs subsided soon after reinduction chemotherapy. Unfortunately, he didn't survive because of a fungal sepsis that developed during the neutropenic state. This case represents a rare neurologic complication of what is currently an uncommon presentation for relapse of acute lymphoblastic leukemia, with acute sciatica and without coexisting epidural or leptomeningeal leukemia.

Abstract
Sciatic nerve injury and dysfunction is not an uncommon cause of lower extremity symptoms in a musculoskeletal practice. We present the case of a man who presented with lower extremity weakness, pain, and cramps, and was initially diagnosed at an outside institution with bilateral S1 radiculopathies and recommended for spine surgery. He came to us for a second opinion. Electrodiagnostic testing revealed an isolated sciatic neuropathy and the patient was referred for imaging, which showed a sciatic nerve sheath tumor. Review of the literature on sciatic neuropathies shows that there can be many possible etiologies of sciatic nerve dysfunction, but that hip arthroplasty continues to be the leading risk factor. Sciatic nerve tumors are not commonly described in the literature and their definitive management remains unclear.

Abstract
Sciatic nerve compression very rarely occurs bilaterally. The authors present a woman with profound lower extremity weakness and sensory abnormality after falling asleep in the head-to-knees yoga position (also called "Paschimottanasana"). Clinical and electrodiagnostic findings are discussed in detail and a brief review of the literature is presented.

Abstract
Abstract
OBJECTIVE AND IMPORTANCE:
Sciatic neuropathy rarely presents in nonpenetrating trauma because of protection of the nerve by the pelvis, the gluteal muscles, and the tissues in the posterior thigh. We present the case of a patient who fell and subsequently developed a traumatic venous varix of the inferior gluteal vein that caused compression sciatic neuropathy.
CLINICAL PRESENTATION:
Seven days after a fall onto her right buttock, the patient developed a painful burning paresthesia in her leg and numbness on the dorsum of her foot. Numerous studies ruled out lumbar spine pathological abnormalities as the cause of the pain. Conventional magnetic resonance imaging revealed a lesion adjacent to the sciatic nerve. Gradient echo and two-dimensional time-of-flight magnetic resonance imaging sequences confirmed this to be a vascular lesion originating from the inferior gluteal vein and compressing the sciatic nerve.
INTERVENTION:
Operative resection obliterated the venous varix, thereby relieving the patient's pain and neurological deficit.
CONCLUSION:
No case of a traumatic venous varix of the inferior gluteal vein compressing the sciatic nerve has been reported to date. Surgical resection was successful in obliterating the lesion and relieving the symptoms.

Abstract
The sciatic nerve can be compressed by a variety of causes, while intervertebral disc herniation is the most common cause of sciatica [Surg. Neurol. 46 (1996) 14], other documented causes include, infection, neoplasm, degenerative disease of a spine, congenital anomalies and traumatic posterior hip dislocation [BMJ 287 (1983) 157]. Sciatic neuropathy in children is uncommon. We present an unusual case of sciatic nerve compression in a 14-year-old-girl that was caused by an avulsion fracture of the ischial tuberosity. The compression was relieved by surgical excision of the avulsed ischial tuberosity.

Abstract
Object. This is a retrospective analysis of 353 surgically treated sciatic nerve lesions in which injury mechanisms, location, time to surgical repair, surgical techniques, and functional outcomes are reported. Results are presented to provide guidelines for management of these injuries.
Methods. One hundred seventy-five patients with buttock-level and 178 with thigh-level sciatic nerve injury were surgically treated at the Louisiana State University Health Sciences Center between 1968 and 1999. Buttock-level injury mechanisms included injection in 64 patients, hip fracture/dislocation in 26, contusion in 22, compression in 19, gunshot wound (GSW) in 17, hip arthroplasty in 15, and laceration in 12; at the thigh level, GSW was the cause in 62 patients, femoral fracture in 34, laceration in 32, contusion in 28, compression in 12, and iatrogenic injury in 10. Patients with sciatic nerve divisions in which positive intraoperative nerve action potentials (NAPs) were found underwent neurolysis and attained at least Grade 3 functional outcomes in 108 (87%) of 124 and in 91 (96%) of 95 buttock- and thigh-level tibial divisions, respectively, compared with 84 (71%) of 119 and 75 (79%) of 95, respectively, in the peroneal divisions. For suture repair, recovery to at least Grade 3 occurred in eight (73%) of 11 buttock-level and in 27 (93%) of 29 thigh-level tibial division injuries, and in three (30%) of 10 buttock-level and 20 (69%) of 29 thigh-level peroneal division lesions. For graft repair, good recovery occurred in 21 (62%) of 34 and in 43 (80%) of 54 buttock- and thigh-level tibial divisions, respectively, even in proximal repairs requiring long grafts, and in only nine (24%) of 37 and 22 (45%) of 49 buttock- and thigh-level peroneal division lesions, respectively.
Conclusions. Surgical exploration and neurolysis after positive NAP readings, or repair with sutures or grafts after negative NAP results are worthwhile in selected cases.

Abstract
Traumatic unilateral sciatic neuropathy secondary to a gunshot wound was diagnosed in a seven-month-old, intact male golden retriever. Findings on neurological assessment, performed after cardiovascular stabilisation, were incompatible with a return to normal limb function. An ankle-foot orthosis was used to correct excessive flexion of the digits and tarsus. This device greatly improved the dog's willingness to ambulate and could serve as an alternative to amputation in companion animals with severe sciatic axonotmesis or neurotmesis. Complications associated with chronic tibiotarsal hyperflexion necessitated a pantarsal arthrodesis one year after initial presentation; the dog also developed cranial cruciate disease in the affected limb three years after the gunshot injury.
