BACKGROUND
The review highlights recent advancements and innovative uses of nerve transfer surgery in treating dysfunctions caused by central nervous system (CNS) injuries, with a particular focus on spinal cord injury (SCI), stroke, traumatic brain injury, and cerebral palsy.
METHODS
A comprehensive literature search was conducted regarding nerve transfer for restoring sensorimotor functions and bladder control following injuries of spinal cord and brain, across PubMed and Web of Science from January 1920 to May 2023. Two independent reviewers undertook article selection, data extraction, and risk of bias assessment with several appraisal tools, including the Cochrane Risk of Bias Tool, the JBI Critical Appraisal Checklist, and SYRCLE's ROB tool. The study protocol has been registered and reported following PRISMA and AMSTAR guidelines.
RESULTS
Nine hundred six articles were retrieved, of which 35 studies were included (20 on SCI and 15 on brain injury), with 371 participants included in the surgery group and 192 in the control group. These articles were mostly low-risk, with methodological concerns in study types, highlighting the complexity and diversity. For SCI, the strength of target muscle increased by 3.13 of Medical Research Council grade, and the residual urine volume reduced by more than 100 ml in 15 of 20 patients. For unilateral brain injury, the Fugl-Myer motor assessment (FMA) improved 15.14-26 score in upper extremity compared to 2.35-26 in the control group. The overall reduction in Modified Ashworth score was 0.76-2 compared to 0-1 in the control group. Range of motion (ROM) increased 18.4-80° in elbow, 20.4-110° in wrist and 18.8-130° in forearm, while ROM changed -4.03°-20° in elbow, -2.08°-10° in wrist, -2.26°-20° in forearm in the control group. The improvement of FMA in lower extremity was 9 score compared to the presurgery.
CONCLUSION
Nerve transfer generally improves sensorimotor functions in paralyzed limbs and bladder control following CNS injury. The technique effectively creates a 'bypass' for signals and facilitates functional recovery by leveraging neural plasticity. It suggested a future of surgery, neurorehabilitation and robotic-assistants converge to improve outcomes for CNS.

Review
BACKGROUND
Conservative therapy is currently the elective treatment for peripheric facial palsy according to scientific literature. The success of conservative therapy is due to physiotherapy and the application of its methods. The aim of this systematic review was to assess mirror therapy, a physiotherapeutic method.
OBJECTIVES
The aim of the following systematic review is to evaluate the effectiveness of using mirror therapy in patients with peripheral paralysis of the seventh cranial nerve.
METHODS
This systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The screening of literature was carried out on Cochrane, PEDro, PubMed/Medline, Scopus and Web of Science databases up until August 2022. All studies were randomized controlled trials (RCTs) and 5 articles met the inclusion criteria and were included in this study. The risk of bias was evaluated with PEDro and Jadad scales.
DISCUSSION
In the present study, we reviewed 5 RCTs that compared mirror therapy with other physiotherapy treatments or placebo to reduce pain, depression and improve range of motion in patients with peripheric facial nerve palsy.
CONCLUSIONS
Further studies are needed to determine the effectiveness of this type of treatment, but nevertheless the data obtained are very encouraging.

Review
Gap injuries to the peripheral nervous system result in pain and loss of function, without any particularly effective therapeutic options. Within this context, mesenchymal stem cell (MSC)-derived exosomes have emerged as a potential therapeutic option. Thus, the focus of this study was to review currently available data on MSC-derived exosome-mounted scaffolds in peripheral nerve regeneration in order to identify the most promising scaffolds and exosome sources currently in the field of peripheral nerve regeneration. We conducted a systematic review following PRISMA 2020 guidelines. Exosome origins varied (adipose-derived MSCs, bone marrow MSCs, gingival MSC, induced pluripotent stem cells and a purified exosome product) similarly to the materials (Matrigel, alginate and silicone, acellular nerve graft [ANG], chitosan, chitin, hydrogel and fibrin glue). The compound muscle action potential (CMAP), sciatic functional index (SFI), gastrocnemius wet weight and histological analyses were used as main outcome measures. Overall, exosome-mounted scaffolds showed better regeneration than scaffolds alone. Functionally, both exosome-enriched chitin and ANG showed a significant improvement over time in the sciatica functional index, CMAP and wet weight. The best histological outcomes were found in the exosome-enriched ANG scaffold with a high increase in the axonal diameter and muscle cross-section area. Further studies are needed to confirm the efficacy of exosome-mounted scaffolds in peripheral nerve regeneration.

Review
BACKGROUND
Although a common injury there is a lack of published primary data to inform clinical management of sports related brachial plexus injuries.
METHODS
A systematic search was completed in Medline, CINAHL, PubMed, SPORTDiscus and Web of Science databases and Google Scholar from inception to August 2023 according to the PRISMA-ScR guidelines. Methodological quality assessment of included articles was with the Joanna Briggs Institute tool. Studies providing primary data as to the rehabilitative management of diagnosed or suspected brachial plexus injuries sustained when playing contact sports were included.
RESULTS
Sixty-five studies were identified and screened, of which, 8 case reports were included, incorporating 10 participants with a mean age of 19.8 (±4.09) years. There was wide heterogeneity in injury severity, injury reporting, physical examination and imaging approaches documented. 9 of 10 participants returned to competitive sports, though follow-up periods also varied widely. Whilst return to play criteria varied between studies, the most consistent indicator was pain-free shoulder range of motion and strength.
CONCLUSIONS
There is a distinct lack of data available to inform evidence-based rehabilitation management of sports related brachial plexus injury. Only 8 individual case reports contain published data reporting on 10 athletes. Further reporting is critical to inform clinical management.

Review
Post-operative pain management is essential for optimizing recovery, patient comfort, and satisfaction. Peripheral nerve blockade, or lumbar plexus block (LPB), has been widely used for analgesia and regional anesthesia. This study explored the existing literature to determine the efficacy of continuous lumbar plexus blockade in managing post-operative pain following hip or femur surgery. Reviewers comprehensively searched electronic databases to identify peer-reviewed scholarly articles reporting the efficacy of lumbar plexus block in managing post-operative pain after orthopedic surgery. The potential articles were carefully selected and assessed for the risk of bias using the Cochrane Collaboration Risk of Bias assessment tool. Data were systematically extracted and analyzed. The literature search yielded 206 articles, 20 of which were randomized controlled trials. Lumbar plexus block demonstrated superior pain relief compared to conventional pain management approaches like general anesthetics. In addition, LPB reduced patients' overall opioid consumption compared to controls, reduced adverse effects, and enhanced functional recovery, which underlines the broader positive impact of meticulous pain management. More patients could walk more than 40 feet after the second day post-operatively among the lumbar plexus group (14.7%) compared to the continuous femoral group (1.3%). Other parameters, including cortisol levels and hemodynamic stability, were evaluated, showing comparable outcomes. Lumbar plexus block is effective in pain management after orthopedic surgery, as shown by the lower pain scores and less opioid consumption. Additionally, patient satisfaction was relatively higher in LPB-treated patients compared to other approaches like general anesthesia.

Review
Several regional anesthesia (RA) techniques have been described for distal upper limb surgery. However, the best approach in terms of RA block success rate and safety is not well recognized. To assess and compare the surgical anesthesia and efficacy of axillary brachial plexus block with other RA techniques for hand and wrist surgery. The attainment of adequate surgical anesthesia 30 min after block placement was considered a primary outcome measure. Additionally, successful block outcomes were required without the use of supplemental local anesthetic injection, systemic opioid analgesia, or the need to convert to general anesthesia. We performed a systematic search in the following databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and CENTRAL. RCTs comparing axillary blocks with other brachial plexus block techniques, distal peripheral forearm nerve block, intravenous RA, and the wide-awake local anesthesia no tourniquet (WALANT) technique were included. In total, 3070 records were reviewed, of which 28 met the inclusion criteria. The meta-analysis of adequate surgical anesthesia showed no significant difference between ultrasound-guided axillary block and supraclavicular block (RR: 0.94 [0.89, 1.00]; = 0.06; I = 60.00%), but a statistically significant difference between ultrasound-guided axillary block and infraclavicular block (RR: 0.92 [0.88, 0.97]; < 0.01; I = 53.00%). Ultrasound-guided infraclavicular blocks were performed faster than ultrasound-guided axillary blocks (SMD: 0.74 [0.30, 1.17]; < 0.001; I = 85.00%). No differences in performance time between ultrasound-guided axillary and supraclavicular blocks were demonstrated. Additionally, adequate surgical anesthesia onset time was not significantly different between ultrasound-guided block approaches: ultrasound-guided axillary blocks versus ultrasound-guided supraclavicular blocks (SMD: 0.52 [-0.14, 1.17]; = 0.12; I = 86.00%); ultrasound-guided axillary blocks versus ultrasound-guided infraclavicular blocks (SMD: 0.21 [-0.49, 0.91]; = 0.55; I = 92.00%). The RA choice should be individualized depending on the patient, procedure, and operator-specific parameters. Compared to ultrasound-guided supraclavicular and infraclavicular block, ultrasound-guided axillary block may be preferred for patients with significant concerns of block-related side effects/complications. High heterogeneity between studies shows the need for more robust RCTs.

Meta-Analysis
Corneal confocal microscopy (CCM) is an ophthalmic imaging technique that enables the identification of corneal nerve fibre degeneration and regeneration. To undertake a systematic review and meta-analysis of studies utilizing CCM to assess for corneal nerve regeneration after pharmacological and surgical interventions in patients with peripheral neuropathy. Databases (EMBASE [Ovid], PubMed, CENTRAL and Web of Science) were searched to summarize the evidence from randomized and non-randomized studies using CCM to detect corneal nerve regeneration after pharmacological and surgical interventions. Data synthesis was undertaken using RevMan web. Eighteen studies including 958 patients were included. CCM identified an early (1-8 months) and longer term (1-5 years) increase in corneal nerve measures in patients with peripheral neuropathy after pharmacological and surgical interventions. This meta-analysis confirms the utility of CCM to identify nerve regeneration following pharmacological and surgical interventions. It could be utilized to show a benefit in clinical trials of disease modifying therapies for peripheral neuropathy.

Review
BACKGROUND
Peripheral neuropathies constitute a diverse array of disorders impacting the peripheral nervous system. Despite extensive research on the therapeutic potential of yoga for various health conditions, its specific effects on peripheral neuropathy remain underexplored.
OBJECTIVE
This review aims to comprehensively investigate the effects, including potential adverse events, of yoga on peripheral neuropathy.
METHODS
A systematic literature search was conducted using the PubMed/Medline electronic database from inception to March 5, 2024. The search strategy involved a combination of relevant Medical Subject Heading (MeSH) terms and keywords related to peripheral neuropathy and yoga. The primary outcome measures assessed in the included studies were the improvement in symptoms and clinical indicators of peripheral neuropathy following yoga interventions. Out of 101 articles initially screened, 16 were considered eligible for inclusion in this review.
RESULTS
The synthesized literature suggests that yoga may serve as a beneficial adjunct in the management of diabetic peripheral neuropathy, chemotherapy-induced peripheral neuropathy, lumbar disc herniation-induced neuropathy, Guillain-Barré Syndrome, and Carpal tunnel syndrome. However, caution is warranted as reported instances of yoga asanas precipitate adverse events such as progressive glaucomatous optic neuropathy, bilateral sciatic nerve neuropathy, and acute loss of motor function due to acute ulnar neuropathy.
CONCLUSIONS
Yoga holds promise as an adjunctive therapy for the management of peripheral neuropathy. Nonetheless, discrepancies in sample size, type of yoga, and intervention duration across studies underscore the need for larger-scale investigations incorporating standardized long-term yoga interventions and objective outcome measures. To mitigate risks of adverse events, patients should practice yoga under the supervision and guidance of institutionally qualified yoga physicians.

Review
INTRODUCTION
The Ten Test (TT) is a touch threshold test that quantifies sensory discrimination by comparing an injured area with a contralateral uninjured area. It's quick, simple, equipment-free and repeatable. However, as a subjective measure, the TT's reliability and applicability need further investigation. This review aimed to investigate if the TT has superior inter- and intra-examiner reliability compared to the widely accepted Weinstein Enhanced Sensory Test (WEST) in a human population of all ages.
METHODS
A systematic search was conducted on major databases from January 1997 to September 2023 and adhered to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol. Outcomes were assessed with a narrative approach. The included articles were critically appraised according to the Quality Assessment of Diagnostic Accuracy Studies two tool.
RESULTS
This review included five articles. High inter-examiner reliability was demonstrated with intraclass correlation coefficient (ICC) values of 0.91 and 0.95, alongside a kappa statistic of 1, as reported by three distinct studies. Intra-examiner reliability displayed some variance, with one study reporting a significant ICC value in four out of six instances. Two studies corroborated that the TT results corresponded with the findings of WEST, each presenting a Spearman rank coefficient of -0.71.
CONCLUSION
Our findings underscore the TT's high inter-examiner reliability, though its intra-examiner reliability exhibited some inconsistencies. Interestingly, certain studies claimed its superiority over the WEST. To validate the TT's use in the clinical setting, more rigorous studies, particularly those comparing pre-operative TT outcomes with intraoperative nerve damage evaluations, are essential.
