AI Article Synopsis

  • The study assessed the effectiveness of TENS therapy on patients with temporomandibular disorders (TMDs) by using ultrasonography to evaluate changes in masseter muscle properties.
  • Fifteen subjects with myofascial pain/myositis underwent six days of TENS therapy, with measurements of pain severity, mouth opening, and masseter thickness taken before and after treatment.
  • Results showed significant improvements post-treatment, including reduced masseter muscle thickness, decreased pain levels, and increased mouth opening, indicating that ultrasonography is a valuable tool for monitoring TENS therapy outcomes.

Article Abstract

Background: The study aimed to determine if ultrasonography of masseter can be used to evaluate the outcome of transcutaneous electrical nerve stimulation (TENS) in subjects with temporomandibular disorders (TMDs) such as myositis and myofascial pain.

Methods: Fifteen TMD subjects with myofascial pain/myositis who satisfied the RDC/McNeil criteria were included in the study. All the subjects were administered TENS therapy for a period of 6 days (30 minutes per session). The mouth opening (in millimeters) and severity of pain (visual analogue scale score) and ultrasonographic thickness of the masseter (in millimeters) in the region of trigger/tender areas was assessed in all the subjects both prior and post TENS therapy. A comparison of the pre-treatment and post-treatment values of the VAS score, mouth opening and masseter thickness was done with the help of a t-test.

Results: There was a significant reduction in the thickness of masseter muscle (P = 0.028) and VAS scores (P < 0.001) post TENS therapy. There was also a significant improvement in the mouth opening (P = 0.011) post TENS therapy.

Conclusions: In the present study, ultrasonography was found to be an effective measuring tool in the assessment of TENS therapy in subjects with myositis and myofascial pain.

Transcutaneous Non-Invasive Vagus Nerve Stimulation: Changing the Paradigm for Stroke and Atrial Fibrillation Therapies?

Biomolecules

November 2024

Department of Anaesthesiology, Intensive Care, Emergency and Pain Medicine, Cerebrovascular Sciences and Neuromodulation, Würzburg University, 97080 Würzburg, Germany.

A new therapeutic approach, known as neuromodulation therapy-which encompasses a variety of interventional techniques meant to alter the nervous system in order to achieve therapeutic effects-has emerged in recent years as a result of advancements in neuroscience. Currently used methods for neuromodulation include direct and indirect approaches, as well as invasive and non-invasive interventions. For instance, the two primary methods of stimulating the vagus nerve (VN) are invasive VN stimulation (iVNS) and transcutaneous VN stimulation (tVNS).

: Brain cancer is notoriously resistant to traditional treatments, including radiotherapy. Microbeam radiation therapy (MRT), arrays of ultra-fast synchrotron X-ray beams tens of micrometres wide (called peaks) and spaced hundreds of micrometres apart (valleys), is an effective alternative to conventional treatments. MRT's advantage is that normal tissues can be spared from harm whilst maintaining tumour control.

Background: Neurogenic bladder dysfunction is a common consequence of stroke, and it substantially impacts the quality of life and functional independence of affected individuals. Traditional treatment modalities have limitations in achieving optimal outcomes. This study aims to explore the effects of electroacupuncture treatment on bladder function and neurogenic bladder urodynamic characteristics in stroke patients.

Background: There is growing interest in use of transcutaneous spinal stimulation (TSS) for people with neurologic conditions both to augment volitional control (by facilitating motoneuron excitability), and to decrease spasticity (by activating inhibitory networks). Various electrode montages are used during TSS, with little understanding of how electrode position influences spinal circuit activation. We sought to identify the thoracolumbar electrode montage associated with the most robust activation of spinal circuits by comparing posterior root-muscle reflexes (PRM reflexes) elicited by 6 montages.
