Transcutaneous Electric Nerve Stimulation

The purpose of this study is to examine the acute and chronic effects of high frequency electrical current transfer (frequently called "TECAR") on pain and functional movement in individuals with a musculoskeletal injury or pain. The participants will be assigned into an experimental or a control group and outcome measures will be measured prior to, after, 24 and 48 hours following a single intervention session (Acute effects) as well as 3 and 6 months after the intervention (chronic effects).

The goal of this clinical trial is to determine whether an intraoral Transcutaneous Electrical Nerve Stimulation (TENS) device can reduce pain during orthodontic alignment and leveling in adolescents and adults. The study aims to compare the effectiveness of the TENS device in reducing pain on one side of the mouth, where the device is used, to the other side, where a non-functioning (placebo) device is applied. The primary questions this study aims to answer are: Does the TENS device effectively reduce pain during orthodontic treatment compared to the placebo? How do patients pain levels differ between the treated and untreated sides of the mouth? Participants will: Have an orthodontic appliance placed on their teeth. Experience the TENS device being applied to one side of their mouth for 2.5 minutes immediately after the appliance placement (brackets and wires). Report their pain levels at various intervals after the procedure (immediately, 2 hours, 6 hours, 12 hours, 24 hours, 48 hours, and 72 hours). This study includes up to 150 participants who are undergoing routine orthodontic treatment. The findings will help researchers understand whether the TENS device can effectively reduce discomfort during orthodontic procedures, potentially leading to better patient care and comfort.

Transcutaneous auricular vagus nerve stimulation (taVNS) is a novel non-invasive neuromodulation technique. Existing evidence suggested that taVNS improves pain management, sleep quality, inflammatory responses, and gastrointestinal recovery after surgery. This study is designed to test the hypothesis that perioperative use of taVNS may improve quality of recovery in patients after major noncardiac surgery.

The purpose of this clinical trial is to determine whether transcutaneous auricular vagus nerve stimulation (taVNS) is suitable for improving sleep disorders in patients with rheumatoid arthritis (RA). It will also evaluate the safety of taVNS. The main questions it aims to answer are: Can taVNS improve the sleep quality of RA patients? What medical issues might RA patients experience while receiving taVNS treatment? Researchers will compare taVNS with a placebo (a similar substance that does not contain the actual treatment) to see if taVNS is effective in improving sleep disorders in RA patients. Participants will: Receive taVNS or sham stimulation daily for 4 weeks Keep a daily sleep diary and visit the hospital once a week for check-ups and tests Record their sleep quality and related symptoms This study aims to provide a new, safe, and effective non-drug therapy for sleep disorders related to RA.

Purpose of study is to evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) for post-operative pain control after a cesarean delivery compared to placebo and no TENS.
