All patients underwent clinical and ultrasonographic examination, and pain intensity was assessed using the Visual Analogue Scale (VAS). Patients were divided into two treatment groups: primary conservative treatment and primary surgical treatment. The primary conservative treatment group included 265 patients who were managed using conservative methods (pharmacotherapy, nerve hydrodissection, administration of steroid anti-inflammatory agents, platelet-rich plasma injections, or botulinum toxin). The primary surgical treatment group comprised 788 patients with warfare injuries to the peripheral nerves of the extremities who required surgical nerve repair, including patients with painful neuromas after limb amputations. Pain intensity (VAS) was reassessed at 1, 3, 6, and 12 months after treatment.</p> <p><strong>Results:</strong> Conservative treatment demonstrated satisfactory outcomes in cases of mild pain syndrome with maintained positive dynamics during the first month from treatment initiation. Surgical treatment of warfare injuries to peripheral nerves resulted in a stable and predictable effect in the majority of cases. However, in the long-term follow-up period, some patients experienced worsening of regenerative pain during skeletal muscle reinnervation. Patients with painful neuromas represented the most challenging subgroup, as pain in these cases was typically chronic and difficult to manage.</p> <p><strong>Conclusions:</strong> Patients with warfare injuries to the peripheral nerves of the extremities should undergo ultrasound examination. In the absence of nerve compression or irritation and with preserved anatomical continuity, treatment should begin with pharmacotherapy; if necessary, nerve hydrodissection or injection therapy with steroids or botulinum toxin may be performed. In cases of significant compression, nerve disruption, or lack of effect after conservative treatment within 6 weeks, surgical intervention is recommended.</p> Andrii S. Lysak Anna Y.

To clarify the indications for isolated versus combined treatment of cSDH and to assess the feasibility of the transradial approach.</p> <p><strong>Materials and methods: </strong>A retrospective cohort study was conducted based on the analysis of prospectively collected data from patients with chronic subdural hematomas who underwent MMAe at I.I. Mechnikov Dnipropetrovsk Regional Clinical Hospital between March 24, 2022, and November 6, 2024. The study included 19 patients who underwent endovascular intervention, either as a standalone procedure or in combination with open surgery. Demographic data, etiological factors, clinical presentation, CT, MRI, and DSA findings were analyzed. Treatment effectiveness was assessed at 1, 3, and 6 months postoperatively.</p> <p><strong>Results: </strong>According to the type of treatment, patients were divided into 3 groups: isolated MMAe — 13 patients (68.4%); primary MMAe followed by surgical drainage — 3 patients (15.8%); primary surgical evacuation followed by MMAE — 3 patients (15.8%). Traumatic cSDH was diagnosed in 12 patients (63.2%), while spontaneous cSDH occurred in 7 patients (36.8%), including two cases with mycotic aneurysms of cortical Middle Cerebral Artery (MCA) branches, which were managed with endovascular deconstructive exclusion and subsequent MMAe. One patient with chronic anemia underwent isolated MMAe. Among all patients, 5 (26.3%) were on anticoagulant/antiplatelet therapy, and hemodynamically significant carotid stenosis was identified in 3 patients (15.8%). Follow-up imaging (CT, MRI) at 6 months demonstrated clinical improvement in 100% of cases, with complete hematoma resolution in 17 patients (89.5%).</p> <p><strong>Conclusions: </strong>MMAe has proven to be highly effective and safe in the management of cSDH, both as a stand-alone method and as an adjunct to conventional surgery. The transradial approach demonstrated advantages in elderly and high-risk patients, contributing to reduced hospitalization times. Furthermore, the use of Onyx<sup>TM</sup> ensured deeper penetration and more durable occlusion of pathological vessels compared to polyvinyl alcohol (PVA) particles. These findings are consistent with current global trends and confirm the promising role of MMAe in cSDH treatment.</p> Vadym A. Perepelytsia Yurii V. Cherednychenko Andrii Y. Miroshnychenko Andrii H.

Transforaminal Lumbar Interbody Fusion (TLIF) is increasingly preferred over Posterior Lumbar Interbody Fusion (PLIF); however regional data in India are limited.</p> <p><strong>Objective: </strong>This prospective study evaluated clinical, radiological, and functional outcomes after TLIF in lumbar spondylolisthesis patients treated at a tertiary center in central India.</p> <p><strong>Methods: </strong>Fifty adult patients with Grade II–IV lumbar spondylolisthesis underwent TLIF. Assessments included pain (Visual Analogue Scale, VAS), disability (Oswestry Disability Index, ODI), neurological status, slip angle correction, fusion rates, and complications pre- and postoperatively. Statistical significance was set at <em>p</em> &lt; 0.05.</p> <p><strong>Results: </strong>Locations L4–L5 (56%) and L5–S1 (44%) were the affected levels. The mean preoperative VAS and ODI scores were 7.4±1.0 and 74±10%. At 6 months follow-up, VAS decreased by 71.6% to 2.1, and ODI by 88% to 9.5% (p &lt; 0.001). Neurological recovery included full motor deficit resolution and 92% sensory improvement. The mean slip angle correction was 14.6±5.3°, and the fusion success rate was 92%. Complications were minimal, including 4% wound infection and 4% transient neurological deficits, with no implant failures.</p> <p><strong>Conclusion: </strong>TLIF shows excellent short-term results, offering substantial pain relief, functional and neurological recovery, and high fusion rates in Indian patients with moderate-to-severe spondylolisthesis. Further studies with larger sample sizes and longer follow-up periods are warranted to validate these findings.</p> Neeraj Prasad Manish Kumar Nirala Manisha Gupta Abhishek Kumar Copyright (c) 2026 Neeraj Prasad, Manish Kumar Nirala, Manisha Gupta, Abhishek Kumar http://creativecommons.org/licenses/by/4.0 2026-03-29 2026-03-29 32 1 40 51 10.25305/unj.339584 Factors contributing to surgical complexity in giant parasagittal and falcine meningiomas: a case-based review https://theunj.org/article/view/338724 <p><strong>Introduction: </strong>Giant parasagittal and falcine meningiomas are surgically challenging due to their frequent involvement of the superior sagittal sinus (SSS), proximity to eloquent cortex, and complex venous anatomy. Although these tumors carry a high operative risk, detailed analyses of surgical difficulty remain limited in the literature.</p> <p><strong>Objective: </strong>This narrative review of published case reports and series aims to delineate the key determinants of surgical complexity in giant parasagittal and falcine meningiomas, including tumor size, sinus involvement, anatomical constraints, and intraoperative decision-making while emphasizing the balance between surgical radicality and patient safety.</p> <p><strong>Methods: </strong>A narrative review and multicase synthesis were performed, analyzing 22 published reports (19 case reports and 3 case series) describing the microsurgical management of giant parasagittal and falcine meningiomas. Studies were included based on the PICOS framework, focusing on tumors ≥5 cm with original surgical and outcome data. Extracted variables included demographics, tumor size, location, SSS involvement, histology, surgical technique, and clinical outcomes<strong>.</strong></p> <p><strong>Results: </strong>A total of 36 patients were identified. Most tumors were parasagittal (52.8%), involved the middle third of the SSS (38.9%), and demonstrated SSS invasion (78.6%), with complete occlusion in 64.3% of cases. Gross total resection was achieved in 75.7% of cases. Pediatric patients (11.1%) were more frequently associated with high-grade histology and intraoperative complications. Tumors involving the middle third of the SSS and those with parasagittal location were consistently associated with increased technical difficulty, venous bleeding, and postoperative deficits. Overall, 72.2% of patients experienced favorable recovery, while 11.1% had poor outcomes, including tumor recurrence or death.</p> <p><strong>Conclusion: </strong>Surgical management of giant parasagittal and falcine meningiomas is technically demanding, particularly in pediatric cases and when tumors involve the parasagittal region or the middle third of the SSS. Careful preoperative venous evaluation and individualized strategies are crucial for optimizing the resection while minimizing complications.</p> Tommy A. Nazwar Nasim Amar Farhad Bal’afif Donny W.

Bibliometric mapping provides insights into emerging trends and knowledge gaps.</p> <p><strong>Objective:</strong> This study aims to map and evaluate international research output on seizure detection in critically ill patients after decompressive craniectomy.</p> <p><strong>Methods:</strong> Relevant literature was collected from Scopus, PubMed, CrossRef, and Google Scholar using the terms ‘decompressive craniectomy AND seizure AND detected’ via the Publish or Perish software. Records were exported in RIS format and analysed with VOSviewer to generate keyword co-occurrence networks, cluster maps, and temporal trend visualizations.</p> <p><strong>Results:</strong> A total of 1,605 publications from 2015–2025 were analyzed. Annual research volume increased, particularly since 2018. The co-occurrence network analysis identified four thematic clusters: (1) clinical outcomes and prognosis, (2) surgical techniques and perioperative management, (3) intracranial pressure and monitoring strategies, and (4) seizure detection and critical neurological care. Overlay analysis revealed a gradual thematic shift toward seizure monitoring and electroencephalography EEG-based approaches in recent years, while density visualization confirmed that seizure detection remains an emerging but relatively underdeveloped research area. The most prolific contributor was identified with 126 publications.</p> <p><strong>Conclusion:</strong> Although publications on decompressive craniectomy have grown rapidly, seizure detection remains a relatively small but growing research topic. Increased focus on neurocritical monitoring indicates future opportunities for developing evidence-based protocols and collaborative studies in this field.</p> Kuat Widodo Saryono Saryono Novita Anggraeni Copyright (c) 2026 Kuat Widodo, Saryono, Novita Anggraeni http://creativecommons.org/licenses/by/4.0 2026-03-29 2026-03-29 32 1 60 68 10.25305/unj.339497 Development and validation of a multilevel scale for quantitative assessment of mechanical exposure in traumatic spinal injuries https://theunj.org/article/view/341693 <p><strong>Objective: </strong>To develop, theoretically substantiate, and perform primary validation of a multilevel (0–10 points) scale for quantitative assessment of the intensity of external mechanical impact in traumatic spinal injuries.</p> <p><strong>Materials and methods: </strong>The study design followed the COSMIN (Consensus-based Standards for the Selection of Health Measurement Instruments) principles for developing and validating medical measurement tools, ensuring an adequate level of scientific validity and reproducibility. A literature review (PubMed, Scopus, Web of Science, 1990–2025) enabled the identification of threshold values and modifying factors, including patient body mass, the transmission coefficient of impulse (<em>T<sub>land)</sub></em>)), and the effective deceleration distance (<em>S<sub>land</sub></em>). Two datasets were used for validation: 40 standardized clinical vignettes and 52 real cases of thoracolumbar junction trauma (Th11–L2) with mandatory verification by computed tomography/magnetic resonance imaging. Construct and criterion validity, inter-rater reliability (ICC, κ), absolute reliability (SEM, MDC<sub>95</sub>), diagnostic accuracy (ROC analysis), agreement level (Bland–Altman), and threshold stability were assessed.</p> <p><strong>Results: </strong>Based on comparative analysis of various approaches, the concept of “equivalent fall height” was proposed as a universal criterion of mechanical exposure in spinal trauma. An 11-level (0–10) quantitative scale and a spine-oriented derived metric were developed. Primary validation demonstrated high inter-rater agreement (ICC(2,1): 0.84 for the basic indicator and 0.79 for the spinal-oriented one; ICC(2,k): 0.95 and 0.92), acceptable absolute precision (SEM 0.80–0.95; MDC<sub>95</sub> 2.2–2.6 points), and stable thresholds (discrepancies exceeding ±1 level occurred in &lt;7% of cases). The metrics showed significant associations with vertebral body wedge deformity (r=0.58), spinal canal compromise (r=0.49), and ordinal injury severity by AO Spine (ρ=0.62; p&lt;0.001). In logistic modeling, each additional 1 m in equivalent fall height nearly doubled the odds of burst/unstable injuries (OR=1.85; 95% CI 1.45–2.38). The diagnostic performance of the scale was confirmed (AUC=0.82) for identifying vertebral fractures (optimal threshold ≈1.3 m; sensitivity – 0.76; specificity – 0.72).</p> <p><strong>Conclusions: </strong>The proposed scale provides a quantitative, mass-neutral, and clinically interpretable measure of the “event severity,” complements morphological classifications, enhances risk stratification, and can be applied for patient triage, diagnostic planning, and multicenter research.</p> Oleksii S.

Progesterone and vitamin D have demonstrated neuroprotective and anti-inflammatory properties in preclinical models; however, their translational efficacy in clinical trials remains inconclusive. Clarifying their therapeutic roles may help inform adjunctive strategies in the acute management of neurotrauma.</p> <p><strong>Objectives: </strong>To assess the neuroprotective effects of progesterone and vitamin D in enhancing functional recovery following moderate to severe TBI, and to compare the clinical efficacy of these agents based on standardized neurological outcome measures derived from randomized controlled trials (RCTs).</p> <p><strong>Methods: </strong>A systematic review and meta-analysis were conducted in accordance with the PRISMA guidelines. Randomized controlled trials (RCTs) were identified through searches of PubMed, EMBASE, Web of Science, and the Cochrane Library, comparing progesterone and/or vitamin D with placebo in patients with traumatic brain injury (TBI). Studies reporting Glasgow Outcome Scale–Extended (GOS-E) outcomes were included. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using Review Manager version 5.4. Study quality and heterogeneity were assessed.</p> <p><strong>Results: </strong>Six RCTs were included: three progesterone trials (n = 1,426) and three vitamin D trials (n = 192). Progesterone showed no significant improvement in functional outcomes compared with placebo (SMD = −0.07; 95% CI: −0.32 to 0.19; p = 0.60; I² = 58%). Vitamin D demonstrated a non-significant trend toward improved outcomes (SMD = 0.37; 95% CI: −0.27 to 1.02; p = 0.26; I² = 78%). Variability in trial design, timing of intervention, and baseline vitamin D deficiency status may have influenced the observed effects.</p> <p><strong>Conclusions: </strong>Although neither agent showed standalone efficacy, their safety and complementary mechanisms suggest promise for combinatorial or biomarker-guided approaches. This meta-analysis highlights the need for early, precision-targeted, and stratified neuroprotective trials in TBI care.</p> Kenzie Ongko Wijaya Nunki Puspita Utomo Muhammad Andika Wibisono Endro Basuki Sadjiman Copyright (c) 2026 Kenzie Ongko Wijaya, Nunki Puspita Utomo, Muhammad Andika Wibisono, Endro Basuki Sadjiman http://creativecommons.org/licenses/by/4.0 2026-03-29 2026-03-29 32 1 92 98 10.25305/unj.337777 Artificial Intelligence algorithms for decision-making in thrombolysis and thrombectomy https://theunj.org/article/view/342454 <p>Acute ischemic stroke is a medical emergency in which every minute of delay results in irreversible loss of brain tissue. The main treatment modalities—intravenous thrombolysis and endovascular thrombectomy—have strict time windows and depend critically on the accuracy of neuroimaging. Conventional image interpretation requires substantial clinical expertise, is time-consuming, and is subject to interobserver variability. Modern artificial intelligence (AI) algorithms open new opportunities for the automated detection of vascular occlusions, assessment of ischemic core volume, and generation of real-time treatment recommendations. The application of these algorithms can significantly reduce the time from patient admission to the initiation of reperfusion therapy, improve the accuracy of patient selection, and standardize clinical decision-making.</p> <p><strong>Objective:</strong> To summarize current evidence on the role of AI algorithms in decision-making for thrombolysis and thrombectomy and to assess their potential to improve the speed and accuracy of patient selection.</p> <p><strong>Materials and methods</strong>: A literature review (2015–2025) was conducted using the PubMed, Scopus, Web of Science, and Google Scholar databases with the keywords “artificial intelligence,” “machine learning,” “deep learning,” “stroke,” “thrombolysis,” and “thrombectomy” to synthesize contemporary data on the use of AI algorithms in clinical decision-making for acute ischemic stroke. Clinical studies, reviews, and protocols describing the application of AI in neuroimaging, prognostication, and patient stratification were analyzed.</p> <p><strong>Results:</strong> Deep learning algorithms (e.g., Viz.ai, e-ASPECTS) enable automated processing of computed tomography and magnetic resonance imaging, rapidly identifying ischemic lesions and vascular occlusions. This reduces the time from diagnosis to treatment by 15–37 minutes, improves the reproducibility of assessments, and optimizes patient selection for reperfusion therapy. Models integrating clinical and neuroimaging data demonstrate superior predictive accuracy and allow consideration of individual patient characteristics.</p> <p><strong>Conclusions:</strong> Artificial intelligence is becoming an integral tool in stroke management by providing rapid, standardized, and objective data analysis. Its implementation reduces “door-to-needle” and “door-to-puncture” times, improves treatment outcomes, and decreases disability. The synergy between clinicians and AI heralds a new era of personalized stroke therapy aimed at preserving brain tissue and saving patients’ lives.</p> Dmytro V. Shchehlov Mykola B.

Neurological status was assessed based on the severity of pain syndrome, the presence of segmental instability was determined. Magnetic resonance imaging, computed tomography, and radiographic findings were evaluated. The following surgical techniques were used: microdiscectomy for lumbar and lumbosacral disc herniation.</p> <p><strong>Results: </strong>Microdiscectomy with interbody cage fusion eliminated manifestations of instability and provided more effective stabilization of the lumbosacral spine compared with microdiscectomy alone. The recurrence rate of disc herniation after microdiscectomy with cage fusion lower (3%) compared with microdiscectomy alone (9%). In the group treated with microdiscectomy and cage fusion, a more pronounced reduction in pain intensity (–82%) and a greater decrease in the Oswestry Disability Index (–81%) were observed, indicating higher effectiveness of the stabilization technique. According to the Macnab and Prolo scales, excellent and good outcomes were recorded more frequently in the microdiscectomy with cage fusion group than in the microdiscectomy group (91% vs 78% and 91% vs. 77%, respectively). The Wilcoxon test confirmed a high level of within-group improvement (p&lt;0.001), while the t-test demonstrated statistically significant differences between the groups.</p> <p><strong>Conclusions: </strong>The lumbosacral segment with an implanted cage is more stable and withstands greater mechanical loads during motion, reduces the recurrence rate of disc herniation, and decreases pain severity. Microdiscectomy with interbody cage fusion may be considered in carefully selected patients with signs of segmental instability as an approach that combines decompression and stabilization and is associated with better long-term clinical outcomes.</p> Ievgenii I.

Disease-specific questionnaires, such as PANQOL and Mayo VSQOL, provide a more sensitive assessment of disease progression and treatment outcomes compared with general instruments. Modern microsurgical techniques aim to preserve facial and cochlear nerve function, which directly influences postoperative QoL.</p> <p><strong>Objective:</strong> To evaluate the QoL of patients with VS using the Ukrainian versions of PANQOL and Mayo VSQOL questionnaires and to validate them according to COSMIN standards.</p> <p><strong>Materials and methods:</strong> The prospective study included 190 patients with VS, divided into three groups: Group I (n=64) — traditional microsurgery (2001–2016); Group II (n=57) — modern microsurgical techniques (2017–2024); Group III (n=69) — observation (“wait-and-scan”). QoL was assessed using PANQOL, Mayo VSQOL, SF-36, QLQ-C30, and BN20 questionnaires. Correlation analysis was performed; statistical significance was set at <em>p</em>&lt;0.05.</p> <p><strong>Results:</strong> Mayo VSQOL scores were significantly higher in Group II compared with Group I in the domains of balance (+33.3%), tinnitus/pain (+36.4%), emotional well-being (+43.1%), memory (+58.4%), and total score (+32.2%). Comparison with Group III also confirmed the advantage of surgical treatment, particularly in emotional well-being and memory (+44.3%). PANQOL demonstrated the greatest improvement in the “Face” domain (+35.6%), while changes in other domains were not statistically significant. Significant correlations were found between PANQOL and Mayo VSQOL results with SF-36, QLQ-C30, and BN20, confirming their validity. Internal consistency was high (PANQOL α=0.75–0.93 preoperatively; α=0.81–0.90 postoperatively; Mayo α=0.763–0.938 preoperatively; α=0.858–0.937 postoperatively). Test–retest reliability (ICC) ranged from 0.60–0.91 for PANQOL and 0.778–0.953 for Mayo. Mayo VSQOL demonstrated higher responsiveness to clinical changes (Cohen’s d=2.11; SRM=1.74) compared with PANQOL (Cohen’s d=0.87; SRM=0.75).</p> <p><strong>Conclusions:</strong> PANQOL and Mayo VSQOL are reliable instruments for assessing QoL in patients with VS. Mayo VSQOL demonstrated higher sensitivity, while PANQOL showed stable correlation with general QoL scales. The use of modern microsurgical techniques substantially improves postoperative QoL in VS patients.</p> Mykola V. Yehorov Vasyl V. Shust Oleg M. Borysenko Volodymyr O.

During clinical examination Phalen’s wrist flexion and wrist extension tests, Hoffmann-Tinel, postural provocation, median nerve compression, and the “tourniquet” tests were positive. Allen's test was negative. There was no atrophy of the thenar muscles, the strength of palmar abduction of the thumb was comparable to that of the right hand. Sensitivity of the fingers was unchanged. Based on the history and clinical examination, a diagnosis of idiopathic carpal tunnel syndrome of the left hand was made. Open carpal tunnel release, mesoepineurolysis of the median nerve, and tenosynovectomy were performed. Intraoperatively, it was found that from the proximal edge of the wound, the trunk of the median nerve was split into two parts, which were reconnected in the area of the exit from the carpal tunnel, forming a “loop” like structure. An hourglass deformity was also noted on both branches of the median nerve. The radial branch of the split nerve was visually thicker than the ulnar branch. Postoperatively, pain and numbness of 1-3 fingers resolved completely.</p> <p>The median nerve bifurcation is extremely difficult to detect preoperatively. In the case of a traumatic complete anatomical injury to the median nerve, one should make sure that this structural anomaly is absent, and if there is a bifurcation of the nerve, an extended revision should be performed and a suture should be placed on both damaged branches.</p> <p>During surgical treatment of carpal tunnel syndrome, it is advisable to check whether the bifurcated nerve runs through a single canal rather than two separate canals. In the latter case, it is necessary to influence both canals during operative or conservative treatment.</p> Irakli B. Goginava Giorgi Murvelashvili Mikheil A. Shavgulidze Mariia V.

According to various authors, ocular involvement accounts for up to 28% of all blast-related injuries. Traumatic brain injury (TBI), which frequently coexists with blast trauma, is complicated by ophthalmic disorders in 84% of cases. This highlights the exceptional vulnerability of the eye to blast-related factors — shock wave, thermal effects, and fragments.</p> <p>The most common injuries include open globe trauma, intraocular foreign bodies, globe rupture, retinal detachment, and traumatic optic neuropathy. Secondary factors (shrapnel, building debris, soil, metal) markedly increase the risk of severe complications such as endophthalmitis, post-traumatic glaucoma, and retinal neovascularization, which often lead to disability.</p> <p>Diagnosis requires a comprehensive approach involving ophthalmological methods (ophthalmoscopy, ultrasound, optical coherence tomography), neurophysiological techniques (visual evoked potentials, electroretinography), and neuroimaging (CT/MRI of the orbits and brain). Their combination enables detection of both local ocular damage and central visual pathway impairment.</p> <p>Treatment includes emergency surgery (globe repair, removal of foreign bodies, vitreoretinal interventions), infection prophylaxis (systemic and local antibiotic therapy), as well as anti-inflammatory and immunomodulatory therapy. Timely prevention of sympathetic ophthalmia is of particular importance. Further rehabilitation involves restorative and functional methods aimed at preserving residual vision and improving patient adaptation.</p> <p>Thus, blast-related injury of the visual analyzer is characterized by multifactorial mechanisms and a high risk of permanent vision loss. Optimal diagnosis and treatment are possible only through a comprehensive multidisciplinary approach with an emphasis on early intervention and long-term rehabilitation.</p> Oleksandr S.

Clinical characteristics, diagnosis, and treatment https://theunj.org/article/view/342189 <p>This paper presents current data on the clinical features, diagnosis, and treatment of post-concussion syndrome (PCS) that develops after mild blast-related traumatic brain injury (mbTBI). It is emphasized that PCS is one of the most common long-term consequences of mbTBI among military personnel exposed to blast waves, which determines the clinical and social relevance of this problem. The diagnostic criteria for PCS according to the International Statistical Classification of Diseases, 10th Revision (ICD-10), and the Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV), are described, as well as the difficulty of differentiating PCS from post-traumatic stress disorder, which frequently co-occurs with PCS in combat veterans. The following symptom groups are identified: cognitive, psychoemotional, somatosensory, autonomic, and vestibular. Particular emphasis is placed on the importance of using neurophysiological methods—quantitative electroencephalography and P300 event-related potentials—to objectify the diagnosis of PCS. The therapeutic approach should be multidisciplinary and personalized, incorporating physical rehabilitation, cognitive-behavioral therapy, sleep hygiene, and pharmacological management (antidepressants, analgesics, botulinum toxin therapy, and hyperbaric oxygen therapy). Research findings indicate the importance of early physical activity.</p> Vadym V. Biloshytsky Yurii V. Zavaliy Alisa V. Pachevska Illia V. Biloshytskyi Copyright (c) 2026 Vadym V.
