Safety of lower extremity neurodynamic exercises in adults with diabetes mellitus: a feasibility study

Efficacy of neural mobilization and Maitland accessory mobilization in patients with tennis elbow- randomized controlled trial

OBJECTIVE

The objective of the study was to evaluate the efficacy of Maitland accessory mobilization and neural mobilization in patients with tennis elbow.

METHOD

Twenty-five patients meeting the selection criteria were randomly assigned to three experimental groups: Group C (conventional treatment), Group B (neural mobilization), and Group A (Maitland mobilization). Quality of life was assessed using the Patient Rated Tennis Elbow Evaluation (PRTEE), while pain, range of motion, and grip strength were evaluated using the Visual Analog Scale (VAS), a universal goniometer, and a handheld dynamometer. The interventions were administered three times per week for four weeks to the respective groups.

RESULTS

Non-parametric tests were employed to analyze the results due to the non-normal distribution of the data (p < 0.05). Both the Wilcoxon signed-rank test and the Kruskal-Wallis test were utilized to assess differences within and between groups. The results of the between-group analysis demonstrated significant differences in pain (p = 0.018) and quality of life (p = 0.045) among the three groups.

CONCLUSION

After a 4-week intervention, all three groups exhibited notable improvements in discomfort levels, grip strength, and quality of life. Notably, Group B demonstrated the most substantial increase in range of motion (ROM) compared to Groups A and C. Consequently, incorporating neural mobilization into the treatment plan is recommended for patients experiencing Tennis Elbow.

The effectiveness of neurodynamic techniques in patients with diabetic peripheral neuropathy: Study protocol for a randomized sham-controlled trial

Background

Diabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes mellitus (DM). DPN is the primary risk factor for diabetic foot ulcers that can cause amputation. Although several observational studies have investigated the morphological and biomechanical characteristics of peripheral nerves in DPN, interventional studies regarding the effectiveness of neurodynamic techniques (NDT) in DPN patients are confined to a handful. The effects of NDT on neuropathy severity, nerve conduction parameters, quality of life (QoL), and mechanosensitivity have not been explored yet in this population.

Materials and Methods

Forty type 2 DPN (T2DPN) patients, diagnosed based on an electrodiagnosis study, will be recruited into two groups. The experimental group will receive the tibial nerve's real proximal and distal slider techniques in addition to DPN standard treatment as a basic treatment, and the control group will receive the tibial nerve's sham proximal and distal slider techniques along with the basic treatment for eight sessions twice a week. Baseline and post-intervention assessments will be based on the Michigan diabetic neuropathy score (MDNS) (primary outcome), tibial nerve conduction parameters, neuropathy-specific quality of life (Neuro QoL) questionnaire, and straight leg raising range of motion (SLR ROM) (secondary outcomes).

Results

This study is expected to last approximately seven months, depending on recruitment. The results of the study will be published in a peer-reviewed journal.

Conclusions

The present study will evaluate the efficacy of NDT on the primary and secondary outcome measurements in DPN patients.

Neurodynamic Treatment Promotes Mechanical Pain Modulation in Sensory Neurons and Nerve Regeneration in Rats

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.

Effect of massage, passive neural mobilization and transcutaneous electrical nerve stimulation on magnetic resonance diffusion tensor imaging (MR-DTI) of the tibial nerve in a patient with type 2 diabetes mellitus induced neuropathy: a case report

BACKGROUND

MR-DTI parameters namely fractional anisotropy (FA) and apparent diffusion coefficient values (ADC) of diffusion imaging demonstrate the directional preference and speed of diffusion of water molecules. The purpose of this case report is to explore the effect of massage, passive neural mobilization and transcutaneous electrical nerve stimulation on MR-DTI of the tibial nerve in a patient with type 2 diabetes mellitus having chronic distal symmetrical sensorimotor neuropathy.

CASE DESCRIPTION

A 63-year-old male with type 2 diabetes mellitus diagnosed with chronic symmetrical sensorimotor diabetic peripheral neuropathy on the basis of medical examination and electrophysiological testing. Altered mechanosensitivity of the tibial nerve was confirmed through neurodynamic testing. MR-DTI revealed severe damage of the tibial nerve as shown by chaotic diffusion of water molecules and damaged microstructural integrity.

INTERVENTION

A total six sessions over 3 weeks including nerve massage in a longitudinal and transverse direction; passive neural mobilization consisting of sliders and tensioners of the tibial nerve; and followed by 15 minutes of continuous transcutaneous electrical nerve stimulation directed along the nerve course.

OUTCOME

FA and ADC values, pain,neuropathy quality of life and range of motion data were collected pre and post intervention. Analysis revealed clinical improvement in all the outcome measures.

CONCLUSION

This case report identified improvement in radiological MR-DTI outcomes following rehabilitation in a patient with diabetic peripheral neuropathy.

Benefits and Harms of Exercise Therapy for Patients With Diabetic Foot Ulcers: A Systematic Review

AIM

Exercise therapy is a core element in the treatment of diabetes, but the benefits and harms for patients with a diabetic foot ulcer (DFU) are unknown. We therefore aimed to systematically review the benefits on health-related quality of life (HRQoL) and harms of exercise therapy for patients with DFU.

METHODS

We searched 6 major databases. We performed citation and reference searches of included studies and contacted authors of ongoing trials. We included randomized controlled trials (RCTs) to assess potential benefits on HRQoL and harms of exercise therapy. Observational studies were included to identify potential harms of exercise therapy.

RESULTS

We included 10 published publications of 9 trials and results from 2 unpublished trials including a total of 281 individuals with DFUs receiving various forms of exercise therapy. Due to lack of HRQoL measurements and high heterogeneity, it was not possible to perform meta-analyses. Results on HRQoL was present in one unpublished study. Harms reported ranged from musculoskeletal problems, increased wound size, to amputation; however, no safe conclusions could be drawn from the available data due to high heterogeneity and risk of bias in the trials.

CONCLUSIONS/INTERPRETATION

Protective strategies are often preferred over therapeutic exercise that might have unforeseen consequences for patients over time. Based on the current literature, no evidence-based recommendations can be provided on the benefits and harms of exercise therapy for patients with DFUs. Well-conducted RCTs are needed to guide rehabilitation including detailed description of adverse events and an exercise program in a semisupervised or fully supervised setting.

A study protocol on nerve mobilization induced diffusion tensor imaging values in posterior tibial nerve in healthy controls and in patients with diabetic neuropathy-multigroup pretest posttest design

Background

Diabetic neuropathy is the commonest chronic disabling complication of diabetes which may lead to amputation and compromising patient’s quality of life. It is characterized by pain, sensation loss associated with neural edema. Diffusion tensor imaging parameter i.e. fraction anisotropy determines the free water proton diffusion in the healthy nerve. Since the diabetes leads to altered mechanosensitivity of the posterior tibial nerve thereby, might interferes with the water molecules movement. Therefore the present clinical trial will provide the evidence of improving the diffusion tensor imaging in the diabetic neuropathy directly by targeting the nerve through nerve mobilization treatment.

Methods

Participants with Type II Diabetes Mellitus induced peripheral neuropathy will be selected randomly on the basis of eligibility criteria and informed consent will be taken. Participants will be recruited into three groups. Group A (experimental group A) will receive neural mobilization technique, Group B (experimental group B) will receive conventional therapy and Group C (control group) will receive sham treatment for 3 weeks. MRI technique, Visual analogue scale and neuropathy specific quality of life questionnaire will be used as assessment tools. Assessment will be taken at baseline and post intervention.

Conclusion

this clinical trial will provide the evidence of efficacy of nerve mobilization in determining the diffusion tensor imaging (DTI) changes in the posterior tibial nerve in patients with diabetic neuropathy. This trial will also be the first one in itself to look at the treatment induced DTI changes in the peripheral nerve.

Upper Limb Neurodynamic Test 1 in patients with Acquired Brain Injury: a cross-sectional study

Introduction: Neurodynamic intervention is used in the treatment of patients with Acquired Brain Injury as a method to inhibit the spasticity or reduce the sensory impairment. Purpose of the study: Assess and compare bilateral median nerve mechanosensitivity and its relationship with physical and functional status in patients with hemiparesis or upper limb paresis after ABI. Materials and Methods: Volunteer Patients from the Brain Injury Rehabilitation Unit of the Hospital Universitario Central de Asturias were evaluated for six months. Taking into account inclusion and exclusion criteria, from the 98 original patients having treatment in the Unit included, only 32 were admitted to the final study. The assessment protocol incorporated as main outcomes: bilateral mechanosensitivity of the median nerve (sensory responses, structural differentiation and maximum range of movement in Upper Limb Neurodynamic Test 1) and as secondary outcomes: hypertonia, sensory impairment, upper limb motor function and Activities of Daily Living performance. Results: Significant differences were found when comparing the bilateral maximum range of movement in Upper Limb Neurodynamic Test 1. No relationship was found between the results of the neurodynamic test of the affected upper limb and the secondary outcomes. Conclusions: Mechanosensitivity disturbance observed in the affected upper limb may benefit from neurodynamic treatment.
