Review
PURPOSE
Cervical radiculopathy due to various mechanical causes is commonly seen, however, cervical vertebral artery dissection (cVAD)-related radiculopathy is very rare with poorly characterized clinical outcomes. Thus, we conducted a systematic review of published literature and reported an institutional case to provide a better illustration of this rare entity.
METHODS
We systematically reviewed the PubMed literature and queried the clinical database at our center for cVAD-related radiculopathy. We described the baseline characteristics of patients with cVAD-related radiculopathy, the involved segment, diagnostic approach and treatment options.
RESULT
14 previously published studies met the inclusion criteria and along with the case we identified in our center, our study included 17 patients total (median age: 35 years, 9 females). C5 was the most commonly affected root and ipsilateral shoulder/arm pain along with shoulder abduction weakness was most common presentation. Antiplatelet or anticoagulant therapy was the treatment of choice. Most cases managed conservatively (82%). Majority of the cases (92%) had either complete or partial resolution of their symptoms.
CONCLUSION
Despite its limitations, this study show that cVAD related radiculopathy is a relatively benign entity with excellent clinical outcomes when managed medically.

Meta-Analysis
Ranking Alpha Lipoic Acid and Gamma Linolenic Acid in Terms of Efficacy and Safety in the Management of Adults With Diabetic Peripheral Neuropathy: A Systematic Review and Network Meta-analysis.
OBJECTIVES
Current medications for diabetic neuropathy (DN) recommended by the American Diabetes Association and American Academy of Neurology do not address the pathologic process of denervation among patients with DN, because ancillary treatments, such as reactive oxygen scavengers, may be needed. The purpose of this work was to summarize the available evidence about the efficacy and safety of alpha lipoic acid (ALA) and gamma linolenic acid (GLA) in the management of DN.
METHODS
Using the search terms [(alpha lipoic acid or ALA or thioctic acid or thioctacid) or (gamma linolenic acid or GLA)] AND [(diabetes or diabetes mellitus) AND (polyneuropathy or neuropathy or sensorimotor polyneuropathy or radiculopathy)], 11 studies were included in this review and combined meta-analysis.
RESULTS
Eight of the 11 articles (73%) reported significant benefit of ALA vs placebo. In the meta-analysis, the Total Symptom Score (TSS) for ALA 600 mg/day (ALA600) was 1.05 points lower (standard mean difference [SMD] -1.05, 95% confidence interval [CI] -2.07 to -0.04, p=0.04, I=98.18%) compared with control at the end of the study. In the network meta-analysis, ALA600 (SMD -1.68, 95% CI -2.8 to -0.6) and GLA (SMD -2.39, 95% CI -4.3 to -0.5) had significantly lower TSSs compared with placebo. Moreover, GLA had the highest probability of being the best (52.7%) for improving DN symptoms. In all studies, most adverse events include gastrointestinal disturbances. In terms of tolerability, no differences were detected between ALA and control groups.
CONCLUSION
ALA and GLA appear to be safe and efficacious biofactors for improvement of DN symptoms.

Meta-Analysis Review
BACKGROUND
Pulsed radiofrequency (PRF) of the lumbar dorsal root ganglion (DRG) has been widely used as a method to relieve lumbar radicular pain (LRP). However, the value of PRF application in LRP patients remains uncertain. This systematic review aimed to compare the effects of PRF of lumbar DRG and LEI in patients with LRP.
METHODS
A literature search was performed using well-known databases for articles published up to May 2023. We included randomized controlled trials (RCTs) that evaluated the effects of PRF compared to LEI with or without steroids. We screened articles, extracted data, and assessed risk of bias in duplicate. The pain scores and Oswestry Disability Index (ODI) scores at 1, 3, and 6 months after procedures were obtained. A random-effects meta-analysis model was applied for outcomes. We evaluated evidence certainty for each outcome using the GRADE scoring system. This review was registered in the PROSPERO (ID: CRD42021253628).
RESULTS
A total of 10 RCTs were included and data of 613 patients were retrieved. We assessed the overall quality of the evidence as very low to moderate. PRF showed no difference in pain scores at 1 (mean difference [MD] -0.80, 95% confidence interval [CI] -1.59 to 0.00, low certainty) and 6 months (MD -2.37, 95% CI -4.79 to 0.05, very low certainty), and significantly improved pain scores at 3 months (MD -1.31, 95% CI -2.29 to -0.33, low certainty). There was no significant difference in ODI score at any interval (very low to low certainty). In the subgroup who underwent a diagnostic block, did not use steroids, and PRF duration greater than 360 s, PRF significantly reduced pain scores at 3 months after procedures.
CONCLUSIONS
We found low quality of the evidence supporting adjuvant PRF to the lumbar DRG has a greater analgesic effect at 3 months after procedures in patients with LRP than LEI. We identified no convincing evidence to show that this treatment improves function. High-quality evidence is lacking, and data were largely derived from short-term effects. Given these limitations, high-quality trials with data on long-term effects are needed.

BACKGROUND
Lumbosacral radicular pain diagnosis remains challenging. Diffusion tensor imaging (DTI) and diffusion weighted imaging (DWI) have potential to quantitatively evaluate symptomatic nerve root, which may facilitate diagnosis.
PURPOSE
To determine the ability of DTI and DWI metrics, namely fractional anisotropy (FA) and apparent diffusion coefficient (ADC), to discriminate between healthy and symptomatic lumbosacral nerve roots, to evaluate the association between FA and ADC values and patient symptoms, and to determine FA and ADC reliability.
STUDY TYPE
Systematic review.
SUBJECTS
Eight hundred twelve patients with radicular pain with or without radiculopathy caused by musculoskeletal-related compression or inflammation of a single, unilateral lumbosacral nerve root and 244 healthy controls from 29 studies.
FIELD STRENGTH/SEQUENCE
Diffusion weighted echo planar imaging sequence at 1.5 T or 3 T.
ASSESSMENT
An extensive systematic review of the literature was conducted in Embase, Scopus, and Medline databases. FA and ADC values in symptomatic and contralateral lumbosacral nerve roots were extracted and summarized, together with intra- and inter-rater agreements. Where available, associations between DWI or DTI parameters and patient symptoms or symptom duration were extracted.
STATISTICAL TESTS
The main results of the included studies are summarized. No additional statistical analyses were performed.
RESULTS
The DTI studies systematically found significant differences in FA values between the symptomatic and contralateral lumbosacral nerve root of patients suffering from radicular pain with or without radiculopathy. In contrast, identification of the symptomatic nerve root with ADC values was inconsistent for both DTI and DWI studies. FA values were moderately to strongly correlated with several symptoms (eg, disability, nerve dysfunction, and symptom duration). The inter- and intra-rater reliability of DTI parameters were moderate to excellent. The methodological quality of included studies was very heterogeneous.
DATA CONCLUSION
This systematic review showed that DTI was a reliable and discriminative imaging technique for the assessment of symptomatic lumbosacral nerve root, which more consistently identified the symptomatic nerve root than DWI. Further studies of high quality are needed to confirm these results.

Review
The main aim of this study was to determine the level of evidence in the literature for the main indications of osteopathy as recommended by the French osteopathy societies. This systematic review followed the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and evaluated articles published between January 2012 and January 2022 with one modification: when level one evidence studies were available, level two to five studies were excluded. Sources included PubMed, the Cochrane library, the French National Health Authority (HAS) and its affiliates. Inclusion criteria were level one published studies on the indications for osteopathic treatment in French and English, and level two to three studies when no level one studies were available. The level of evidence assessment was based on the Oxford Centre for Evidence-Based Medicine (OCEBM) Levels of Evidence classification. The primary outcome was the level of evidence in the literature supporting osteopathic practices. The secondary outcome was to assess French professional osteopathy recommendations and French HAS guidelines in relation to the scientific literature. A total of 51 articles and nine recommendations from the HAS and its affiliates met the inclusion criteria for the systematic review. Analysis of the studies revealed 41 osteopathic indications from French osteopathy societies for musculoskeletal, neurosensory, psychological, pediatric, gynecological, digestive, and pulmonary disorders. High-level scientific evidence supported the use of osteopathy for low back pain, sciatica, cervical radiculopathy, and ankle sprain. There was moderate evidence for tension headache, temporomandibular joint disorder, endometriosis, and low back and pelvic pain in pregnant women. HAS recommended five indications, while nine indications were supported in the scientific literature. Osteopathy has been shown to have evidence-based benefits for a range of conditions, in particular for musculoskeletal and neurosensory disorders.

Review
Lumbar radiculopathy causes lower back and lower extremity pain that may be managed with neural mobilization (NM) techniques. This meta-analysis aims to evaluate the effectiveness of NM in alleviating pain and reducing disability in patients with lumbar radiculopathy. We hypothesized that NM would reduce pain and improve disability in the lumbar radiculopathy population, leveraging the statistical power of multiple studies. Electronic databases from their inception up to October 2023 were searched for randomized controlled trials (RCTs) that explored the impact of NM on lumbar radiculopathy. Our primary outcome measure was the alteration in pain intensity, while the secondary one was the improvement of disability, standardized using Hedges' . To combine the data, we employed a random-effects model. A total of 20 RCTs comprising 877 participants were included. NM yielded a significant reduction in pain intensity (Hedges' = -1.097, 95% CI = -1.482 to -0.712, < 0.001, I2 = 85.338%). Subgroup analyses indicated that NM effectively reduced pain, whether employed alone or in conjunction with other treatments. Furthermore, NM significantly alleviated disability, with a notable effect size (Hedges' = -0.964, 95% CI = -1.475 to -0.453, < 0.001, I2 = 88.550%), particularly in chronic cases. The findings provide valuable insights for clinicians seeking evidence-based interventions for this patient population. This study has limitations, including heterogeneity, potential publication bias, varied causal factors in lumbar radiculopathy, overall study quality, and the inability to explore the impact of neural pathology on NM treatment effectiveness, suggesting opportunities for future research improvements.

Review
BACKGROUND
The validity of the ULTT is unclear, due to heterogeneity of test procedures and variability in the definition of a positive test OBJECTIVE: To evaluate test procedures and positive diagnostic criteria for the upper limb tension test (ULTT) in diagnostic test accuracy studies.
METHODS
A systematic review of diagnostic accuracy studies was performed. We conducted a search of the DiTA (Diagnostic Test Accuracy) database and selected primary studies evaluating the diagnostic accuracy of the ULTT. We assessed risk of bias, performed data extraction on study characteristics, test procedures, and positive diagnostic criteria, and performed a descriptive analysis.
RESULTS
We included nine studies (681 participants), four diagnosing people with cervical radiculopathy (CR), four diagnosing people with carpal tunnel syndrome (CTS), and one included both CR and CTS. The risk of bias varied between 2 and 6 out of 6 positive items. Eight studies reported on the ULTT1 (median nerve). Overall, all studies clearly described their test procedures and positive diagnostic criteria although the order of movements and the diagnostic criteria between studies varied. We suggest a more standardised test procedure for the ULTT1 to consist of: 1) stabilising the shoulder in abduction, 2) extending the wrist/fingers, 3) supinating the forearm, 4) externally rotating the shoulder, 5) extending the elbow, and finally 6) performed structural differentiation by side bending (lateral flexion) of the neck. This proposed test procedure should reproduce the symptoms and enables the clinician to evaluate whether symptoms increase/decrease when stressing or relaxing the nerves.
CONCLUSION
Based on our findings we proposed a more standardised test procedure for the ULTT1 with accompanying positive diagnostic criteria to facilitate homogeneity in future diagnostic accuracy studies of the ULTT.

Meta-Analysis
BACKGROUND
Cervical spondylotic radiculopathy is a serious and common degenerative disease of the cervical spine due to irritation and compression of the nerve roots of the cervical spine, resulting in a series of clinical symptoms based on sensory, motor and reflex disorders, such as numbness and pain in the neck, shoulders, upper limbs and fingers. Acupuncture is highly effective in treating CSR and has become a common treatment accepted by patients. This study aims to systematically review and analyze existing randomized controlled trials (RCTs) to evaluate the efficacy and safety of acupuncture in the treatment of CSR.
METHODS
We used the following eight databases for literature data search: PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, China Biology Medicine Disc ( CBMdisc), Wanfang Database and China Science and Technology Journal Database (VIP). The search consisted of randomized controlled studies of acupuncture for CSR between 2000 and 2020 and the methodological quality of the included studies was assessed according to the Cochrane Collaboration's "Risk of Bias Assessment Tool."RevMan 5.4 software was used for statistical analysis only. Study screening, data extraction and statistics, and assessment of the risk of bias of the included studies were performed independently by two reviewers.
RESULT
27 studies with 3124 patients were included. The results of the meta-analysis of the total efficiency index for acupuncture for CSR were [RR = 1.14,95% CI (1.09,1.19)]. The results of the meta-analysis of the PPI index were [MD = -0.35, 95% CI (-0.61,-0. 09)]. The results of META analysis of the total effective rate, VAS score, PRI(A) score, PRI(S) score and PRI(T) score showed heterogeneity in the studies included for each outcome index, and sources of heterogeneity were sought through subgroup analysis and sensitivity analysis to ensure more stable and reliable data results. The results of the combined meta-analysis showed that the treatment group was significantly more effective than the control group and more effective in lowering the nerves to reduce the pain index in patients with CSR, with a statistically significant difference (P<0.05). This indicates that acupuncture treatment is superior to traction for CSR.
CONCLUSION
Acupuncture is significantly more effective than traction therapy in the treatment of cervical spondylosis and can reduce the pain index of patients with CSR.

Spine Apr 2024A systematic review and meta-analysis. (Meta-Analysis)
Meta-Analysis
STUDY DESIGN
A systematic review and meta-analysis.
OBJECTIVE
The objective of this study is to examine the impact of the learning curve for endoscopic cervical foraminotomy for clinical outcomes and patient safety.
SUMMARY OF BACKGROUND DATA
Endoscopic cervical foraminotomy is a minimally invasive surgical technique emerging in the literature for surgical management of cervical radiculopathy without the use of open incision. The adoption of endoscopic cervical foraminotomy may be hindered by the learning curve, although no review and meta-analysis exists to date on the topic.
MATERIALS AND METHODS
A systematic review and meta-analysis was performed using PubMed, CINAHL, and MEDLINE from database inception until July 11, 2023. Inclusion criteria were articles that examined endoscopic cervical foraminotomy, reported outcomes, and/or complications for endoscopic cervical spine surgery relevant to the learning curve and had full-text. A random effects meta-analysis was performed for outcomes and complications.
RESULTS
A total of three articles (n=203 patients) were included from 792 articles initially retrieved. The learning curves from four surgeons were examined with a FWM 21 procedures until the competency phase. There was no significant difference in the postoperative hospitalization length ( P =0.669), postoperative recovery room time ( P =0.415), intraoperative blood loss ( P =0.064), and total complication rates (10.9% vs . 1.2%, P =0.139) between endoscopic cervical foraminotomy procedures performed in the learning phase as compared with the competency phase of the learning curve. There was a significant decrease in operative time from the learning phase to the competency phase ( P =0.005).
CONCLUSION
Competency was achieved on the learning curve for endoscopic cervical foraminotomy after about 21 procedures. There is no significant difference in postoperative hospitalization time, postoperative recovery room time, intraoperative blood loss, and complication rates between the learning phase and the competency phase of the learning curve for endoscopic cervical foraminotomy, noting the relatively small sample size of this study that may underpower this finding.
