Comparison of neural mobilization and conservative treatment on pain, range of motion, and disability in cervical radiculopathy: A randomized controlled trial. PLoS One 2022; 17:e0278177. [PMID: 36472990 PMCID: PMC9725158 DOI: 10.1371/journal.pone.0278177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 11/12/2022] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE The objective of the study was to compare the effectiveness of neural mobilization technique with conservative treatment on pain intensity, cervical range of motion, and disability. METHODS It was a randomized clinical trial; data was collected from Mayo Hospital, Lahore. Eighty-eight patients fulfilling the sample selection criteria were randomly assigned into group 1 (neural mobilization) and group 2 (conventional treatment). Pain intensity was measured on a numeric pain rating scale, range of motion with an inclinometer, and functional status with neck disability index (NDI). Data were analyzed using SPSS, repeated measure ANOVA for cervical ranges and the Friedman test for NPRS and NDI were used for within-group analysis. Independent samples t-test for cervical ranges and Mann-Whitney U test for NPRS and NDI were used for between-group comparisons. RESULTS There was a significant improvement in pain, disability, and cervical range of motion after the treatment in both groups compared to the pre-treatment status (p < 0.001), and when both groups were compared neural mobilization was more effective than conventional treatment in reducing pain and neck disability (p < 0.001), but there was no significant difference present in the mean score of cervical range of motion between both groups. (p>0.05). CONCLUSIONS The present study concluded that both neural mobilization and conservative treatment were effective as an exercise program for patients with cervical radiculopathy, however, neural mobilization was more effective in reducing pain and neck disability in cervical radiculopathy.

Abstract
Background Stroke is the most common and serious neurological condition, which can lead to death, limited functionality, and reduced quality of life. Studies with conflicting results and various methodological limitations have been conducted to assess the effectiveness of neurodynamic interventions for patients with stroke. Objective This systematic review and meta-analysis aimed to investigate the pooled effectiveness of different neurodynamic interventions on patients with stroke. Methods The PubMed, PEDro, and Google Scholar databases will be searched for studies published with full text in the English language from inception to date. Randomized controlled trials evaluating the effect of different neurodynamic techniques on patients with stroke will be included. The primary outcome measures will include pain, disability/function, and quality of life. Secondary outcome measures will include physical performance measures such as balance, range of motion, muscle strength, and specific diagnostic and neurodynamic test outcomes. The screening, data extraction, and methodological quality assessment will be performed by two independent reviewers. The PEDro scale will be used to systematically appraise the methodological quality. Review Manager V.5.4 software will be used for statistical analysis. Weighted mean difference or standardized mean difference with 95% CIs and P values will be used to calculate the treatment effect for each outcome variable. Results Search terms and search databases have been identified. The data extraction sheet has also been developed. This study is expected to be completed by the end of 2022. Conclusions This study will provide up-to-date evidence on the effectiveness and use of neurodynamic interventions for patients with stroke in clinical practice.

Neurodynamic Treatment Promotes Mechanical Pain Modulation in Sensory Neurons and Nerve Regeneration in Rats. Biomedicines 2022; 10:biomedicines10061296. [PMID: 35740318 PMCID: PMC9220043 DOI: 10.3390/biomedicines10061296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 05/24/2022] [Accepted: 05/29/2022] [Indexed: 02/04/2023] Open
Abstract
Background: Somatic nerve injuries are a rising problem leading to disability associated with neuropathic pain commonly reported as mechanical allodynia (MA) and hyperalgesia. These symptoms are strongly dependent on specific processes in the dorsal root ganglia (DRG). Neurodynamic treatment (NDT), consisting of selective uniaxial nerve repeated tension protocols, effectively reduces pain and disability in neuropathic pain patients even though the biological mechanisms remain poorly characterized. We aimed to define, both in vivo and ex vivo, how NDT could promote nerve regeneration and modulate some processes in the DRG linked to MA and hyperalgesia. Methods: We examined in Wistar rats, after unilateral median and ulnar nerve crush, the therapeutic effects of NDT and the possible protective effects of NDT administered for 10 days before the injury. We adopted an ex vivo model of DRG organotypic explant subjected to NDT to explore the selective effects on DRG cells. Results: Behavioural tests, morphological and morphometrical analyses, and gene and protein expression analyses were performed, and these tests revealed that NDT promotes nerve regeneration processes, speeds up sensory motor recovery, and modulates mechanical pain by affecting, in the DRG, the expression of TACAN, a mechanosensitive receptor shared between humans and rats responsible for MA and hyperalgesia. The ex vivo experiments have shown that NDT increases neurite regrowth and confirmed the modulation of TACAN. Conclusions: The results obtained in this study on the biological and molecular mechanisms induced by NDT will allow the exploration, in future clinical trials, of its efficacy in different conditions of neuropathic pain.

Quantifying the Elasticity Properties of the Median Nerve during the Upper Limb Neurodynamic Test 1. Appl Bionics Biomech 2022; 2022:3300835. [PMID: 35355794 PMCID: PMC8958106 DOI: 10.1155/2022/3300835] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 01/29/2022] [Accepted: 03/04/2022] [Indexed: 12/04/2022] Open
Abstract
Background The upper limb neurodynamic test 1 (ULNT1) consists of a series of movements that are thought to detect an increase in neuromechanical sensitivity. In vivo, no trail was made to quantify the association between the nerve elasticity and different limb postures during ULNT1. Objectives (1) To investigate the relationship between nerve elasticity and limb postures during ULNT1 and (2) to investigate the intra- and interoperator reliabilities of shear wave elastography (SWE) in quantifying the elasticity of median nerve. Methods Twenty healthy subjects (mean age: 19.9 ± 1.4 years old) participated in this study. The median nerve was imaged during elbow extension in the following postures: (1) with neutral posture, (2) with wrist extension (WE), (3) with contralateral cervical flexion (CCF), and (4) with both WE and CCF. The intra- and interoperator reliabilities measured by two operators at NP and CCF+WE and intraclass correlation coefficients (ICCs) were calculated. Results The intraoperator (ICC = 0.72–0.75) and interoperator (ICC = 0.89–0.94) reliabilities for measuring the elasticity of the median nerve ranged from good to excellent. The mean shear modulus of the median nerve increased by 53.68% from NP to WE+CCF. Conclusion SWE is a reliable tool to quantify the elasticity of the median nerve. There was acute modulation in the elasticity of the median nerve during the ULNT1 when healthy participants reported substantial discomfort. Further studies need to focus on the elasticity properties of the median nerve in patients with peripheral neuropathic pain.

Abstract
We hypothesize that the sciatic nerve in the subgluteal space has a specific behavior during internal and external coxofemoral rotation and during isometric contraction of the internal and external rotator muscles of the hip. In 58 healthy volunteers, sciatic nerve behavior was studied by ultrasound during passive internal and external hip rotation movements and during isometric contraction of internal and external rotators. Using MATLAB software, changes in nerve curvature at the beginning and end of each exercise were evaluated for longitudinal catches and axial movement for transverse catches. In the long axis, it was observed that during the passive internal rotation and during the isometric contraction of external rotators, the shape of the curve increased significantly while during the passive external rotation and the isometric contraction of the internal rotators the curvature flattened out. During passive movements in internal rotation, on the short axis, the nerve tended to move laterally and forward, while during external rotation the tendency of the nerve was to move toward a medial and backward position. During the isometric exercises, this displacement was less in the passive movements. Passive movements of hip rotation and isometric contraction of the muscles affect the sciatic nerve in the subgluteal space. Retrotrochanteric pain may be related to both the shear effect of the subgluteus muscles and the endoneural and mechanosensitive aggression to which the sciatic nerve is subjected.

Musculoskelet Sci Pract 2021; 52:102349. [PMID: 33618231 DOI: 10.1016/j.msksp.2021.102349] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 02/03/2021] [Accepted: 02/06/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND A segmental, contra-lateral cervical lateral glide (CCLG) mobilization technique is effective for patients with cervical radiculopathy (CR). The CCLG technique induces median nerve sliding in healthy individuals, but this has not been assessed in patients with CR. OBJECTIVE This study aimed to 1) assess longitudinal excursion of the median nerve in patients with CR and asymptomatic participants during a CCLG movement, 2) reassess nerve excursions following an intervention at a 3-month follow-up in patients with CR and 3) correlate changes in nerve excursions with changes in clinical signs and symptoms. DESIGN Case-control study. METHODS During a computer-controlled mechanically induced CCLG, executed by the Occiflex™, longitudinal median nerve excursion was assessed at the wrist and elbow with ultrasound imaging (T0) in 20 patients with CR and 20 matched controls. Patients were re-assessed at a 3-month follow-up (T1), following conservative treatment including neurodynamic mobilization. RESULTS There was a significant difference between patients and controls in the excursion of the median nerve at both the wrist (Mdn = 0.50 mm; IQR = 0.13-1.30; 2.10 mm (IQR = 1.42-2.80, p < 0.05)) and elbow (Mdn = 1.21 mm (IQR = 0.85-1.94); 3.49 mm (IQR = 2.45-4.24, p < 0.05)) respectively at T0. There was also a significant increase in median nerve excursion at both sites between T0 and T1 in those with CR (Mdn = 1.96, 2.63 respectively). Wilcoxon Signed-Ranks Test indicated median pre-test ranks (Mdn = 0.5, 1.21; Z = - 3.82, p < 0.01; Z = -3.78, p < 0.01 respectively) and median post-test ranks. There was a strong correlation between improvement in median nerve excursion at the elbow at T1 and improvement in pain intensity (r = 0.7, p < 0.001) and functional limitations (r = 0.6, p < 0.01). CONCLUSION Longitudinal median nerve excursion differs significantly between patients with CR and asymptomatic volunteers at baseline, but this difference is no longer present after 3 months of conservative physiotherapy management. Improvement in nerve excursion correlates with improvement in clinical signs and symptoms.

Abstract
Objective The purpose of this case report was to describe the chiropractic management of thoracolumbar syndrome using multimodal therapies. Clinical Features A 33-year-old woman with 3 weeks of back pain presented to a chiropractic clinic. Nerve tension tests and local tenderness were present in a pattern described by Maigne, and she was diagnosed with thoracolumbar syndrome (Maigne syndrome) at her initial visit. Intervention and Outcomes The Oswestry Disability Index for low back pain (62%), STarT low back screen tool for clinical outcomes (6 points total, with a 2-point subscale), numeric pain rating scale (6/10 constant, 10/10 with provocation), and test-retest exercise audits were outcome measures. She received 3 treatment sessions, each with progressive exercise audits, and discharged with advice. At discharge, the patient scores substantially improved (Oswestry Disability Index: 8%, STarT: 1 point total, numeric pain rating scale: 1/10, 10% of the time), and she exhibited greater confidence in home care. Endurance tests were performed to establish baselines for future care, which included static back endurance test (timed 52 seconds) and side bridge endurance test (timed 43 seconds). Conclusion The patient responded positively to chiropractic care. After a short course of care, the patient reported reduced pain, alleviated symptoms, and improved physical function.

Abstract
Study Design Systematic review with meta-analysis. Objectives To determine the efficacy of neural mobilization (NM) for musculoskeletal conditions with a neuropathic component. Background Neural mobilization, or neurodynamics, is a movement-based intervention aimed at restoring the homeostasis in and around the nervous system. The current level of evidence for NM is largely unknown. Methods A database search for randomized trials investigating the effect of NM on neuromusculoskeletal conditions was conducted, using standard methods for article identification, selection, and quality appraisal. Where possible, studies were pooled for meta-analysis, with pain, disability, and function as the primary outcomes. Results Forty studies were included in this review, of which 17 had a low risk of bias. Meta-analyses could only be performed on self-reported outcomes. For chronic low back pain, disability (Oswestry Disability Questionnaire [0-50]: mean difference, -9.26; 95% confidence interval [CI]: -14.50, -4.01; P<.001) and pain (intensity [0-10]: mean difference, -1.78; 95% CI: -2.55, -1.01; P<.001) improved following NM. For chronic neck-arm pain, pain improved (intensity: mean difference, -1.89; 95% CI: -3.14, -0.64; P<.001) following NM. For most of the clinical outcomes in individuals with carpal tunnel syndrome, NM was not effective (P>.11) but showed some positive neurophysiological effects (eg, reduced intraneural edema). Due to a scarcity of studies or conflicting results, the effect of NM remains uncertain for various conditions, such as postoperative low back pain, cubital tunnel syndrome, and lateral epicondylalgia. Conclusion This review reveals benefits of NM for back and neck pain, but the effect of NM on other conditions remains unclear. Due to the limited evidence and varying methodological quality, conclusions may change over time. Level of Evidence Therapy, level 1a. J Orthop Sports Phys Ther 2017;47(9):593-615.
