18 Clinical Trials for Various Conditions
This study is to determine if the auricular microstimulator produces the expected increase in HRV.
Children referred to the pediatric urology clinic for primary nocturnal enuresis will be screened for enrollment. Patients who fail behavioral therapy and who meet inclusion criteria will be offered therapy with a TENS unit. Patients will be randomized into four groups. Group 1 will be the direct bladder stimulation arm with electrodes placed onto the abdomen in the suprapubic region directly over the bladder. Group 2 will be the distal neural loop arm with electrodes placed over the posterior tibial nerve. Group 3 will be the proximal neural loop arm with electrodes placed about 2-3 cm lateral to the midline in the sacral region at the level of S3. Group 4 will be the control arm with electrodes placed on the scapula. We will aim to recruit 32 patients per group for a total of 128 patients. The patients will be provided with a TENS unit (TENS 3000 Analog) and electrode pads and caretakers instructed on how to use the apparatus. The TENS sessions will be performed nightly before bed for 15 minutes. TENS units will be set at a frequency of 10 Hz, and intensity determined by the sensitivity threshold of the patient. Diaries including nighttime incontinence episodes and a "wet sheet" scale (dry, damp, wet, soaked) will be recorded, along with any adverse reactions to the TENS unit. Patients will be followed up after one month of TENS with evaluation including the Pediatric Urinary Incontinence Questionnaire, a validated tool for measuring quality of life in children with bladder dysfunction; this questionnaire will be filled out prior to starting TENS treatment in order to compare the effect of treatment on QOL. . They will then follow up on these parameters again after another month (one month off of TENS therapy) to assess the durability of treatment effect. The data will be collected at different time points (baseline, 1 month, 2 months) for each group by itself and the groups compared against each other using statistical analysis.
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.
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.
This between-subject, longitudinal pilot study in healthy college students aims to explore the acceptability and preliminary outcomes of two novel and complementary interventions that may improve stress and sleep: transcutaneous vagus nerve stimulation (tVNS) and a mobile mindfulness intervention.
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive modality that utilizes electrical currents to modulate pain in populations with acute and chronic pain. TENS has been demonstrated to produce hypoalgesic effects in postoperative pain, fibromyalgia, knee osteoarthritis, and healthy subjects. Transcutaneous auricular vagus nerve stimulation (TaVNS) is a non-invasive modality that modulates the vagus nerve by stimulating its auricular branches. The effects of the combination of TENS and TaVNS on producing an analgesic response have not been studied. Considering that TENS and TaVNS both stimulate similar analgesic pathways but through different means of activation, the investigators can hypothesize that a combination of both methods can produce a more pronounced analgesic response. Therefore, the objective of this study is to assess the hypoalgesic effect of a combination of TENS and TaVNS in pain-free subjects. The study will be a simple crossover design conducted at the University of Hartford. Subjects will be recruited from the University of Hartford population via oral communication, digital flyers, and posters on campus. Thirty participants will undergo two sessions in a crossover manner with one week in between. During one session, the participants will receive TENS with active TaVNS and the other session will be a placebo procedure (TENS with placebo TaVNS). The order of these sessions will be randomized. Importantly, the pressure pain threshold (PPT) and heat pain threshold (HPT) assessors will be blinded to the treatment category. For active TaVNS, a frequency of 25 Hz will be applied with a pulse duration of 200 µs. For placebo TaVNS, the intensity will be increased to a sensory level and then decreased to 0 mA. High frequency TENS of 100Hz will be applied in both sessions, with a pulse duration of 200 µsec, asymmetrical biphasic square waveform, and intensity of maximal tolerance without pain. TENS and TaVNS will be turned on for 30 minutes after a baseline measurement of outcomes. TENS and TaVNS will then be turned off, but the electrodes will remain on until completion of post-treatment assessment. Pressure pain threshold, heat pain threshold, blood pressure, oxygen saturation and heart rate will be tested 4 times: Once pre-intervention, once during intervention, once immediately after the intervention and once 15 minutes post-intervention.
The purpose of this study is to demonstrate the pain relieving effect of neuromuscular electrical stimulation that is applied for the purpose of increasing muscle force output.
Incontinence associates with military service and post-traumatic stress disorder in both male and female Veterans. Neurogenic detrusor overactivity (NDO) is caused by spinal cord injury or disorder, or peripheral neurodegenerative conditions, and causes urine leakage at low volumes. NDO is disproportionately experienced by Veterans and treatment effectiveness varies greatly between individuals. This project will demonstrate the feasibility of a new type of nerve stimulation-triggered sacral neuromodulation-to treat NDO in Veterans. A wireless bladder sensor will be inserted into the bladder to transmit a feedback signal enabling stimulation from a percutaneous lead. The wireless sensor will also measure NDO symptoms during simulated activities of daily living without catheters. Catheter-free detection of bladder activity will improve the outcomes of neuromodulation evaluations for Veterans with NDO. Future work could use the triggered neuromodulation system to study other methods of nerve stimulation to treat bladder, bowel, or sexual dysfunction.
A recent report (Morera Maiquez et al 2020) described reduced tic severity in people with Tourette syndrome during 1-minute epochs of median nerve stimulation (MNS) at 10 Hz. Among the various questions still to be answered is the question of whether a device to administer MNS is practical for use in a chronic, real-world setting. This study will recruit participants who complete the clinic-based, blinded, randomized controlled trial, https://clinicaltrials.gov/ct2/show/NCT04731714, to determine the real-world usage and apparent utility of median nerve stimulation in people with chronic tics.
Idiopathic Chronic Orchialgia (i.e., testicular pain) is a challenging condition to treat, with unresolved testicular pain leading to distress, diminished activities of daily living and decreased quality of life. Testicular Pain may be caused by a tumor, hernia, infection, trauma, vein compression, cysts, and/or postoperative or radiating pain, though is often times unknown. Non-pharmacologic, conservative pain reduction interventions include heat, ice, scrotal support, physical therapy, and/or counseling, and should often be used as first line of defense. More aggressive, invasive, and non-conservative medical treatment options include medications, nerve blocks, and/or surgery, each of which may be effective, but may be invasive and/or cause serious side effects. However, there is no standard of care for managing the testicular pain and many men do not respond to current biomedical or nonpharmacologic treatment options. Novel, non-invasive treatment options are needed for ICO to improve distress, daily living activities, and quality of life. Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacologic intervention for acute and chronic pain. This treatment involves the application of electric current through the skin; it is safe, easy to use, and inexpensive. Despite the impact and distress associated with Testicular Pain, only one known study examined the efficacy of TENS for this condition. A 2018 double-blind, randomized controlled study of people with Testicular Pain reported that TENS improved pain and quality of life significantly more than the control condition (analgesia only). This 2018 study lacked a placebo control condition (i.e., unknown whether pain relief was due to the placebo effect, where knowing an intervention is happening leads to an expectation that pain will decrease, and therefore pain perception decreases independent of the intervention). Thus, the aim of this study is to examine the efficacy of TENS on Testicular Pain using a randomized, placebo-controlled design. The results of this study will be used to inform a larger, federally-funded study. i. Primary Aim: To assess the efficacy of TENS for Testicular Pain ii. Secondary Aim: To assess the feasibility of TENS for Testicular Pain iii. Third Aim: To assess the tolerability of TENS for Testicular Pain iii. To assess associations between dispositional pain catastrophizing on responsiveness to the TENS intervention.
Results from the University of Nottingham suggested that rhythmic median nerve stimulation (MNS) improves tic symptoms in Tourette syndrome (TS). The investigators will (1) provide a first replication of their study, (2) test the hypothesized electrophysiological mechanism and rule out a placebo effect as cause for the symptomatic benefit, and (3) gather information on the duration of effect after the end of stimulation and on individual characteristics that predict improvement with simulation. Completion of these Aims will give a clear go/no-go signal for a future clinical trial of chronic MNS delivered by a yet-to-be-developed wristwatch-style device. NOTE: This study is not intended to evaluate a specific device for future use. Rather it is a study to determine the action of pulsed electrical stimulation on tic symptoms and to gain early evidence of effectiveness. This is a non-significant risk device study.
Most individuals with spinal cord injury (SCI) have residual nerve circuits. The investigators aim to strengthen those circuits to improve motor recovery after injury. To do this, the investigators are attempting to pair electrical and magnetic stimulation with physical training targeted toward the connections between nerve circuits. Past studies by other groups have shown that synapse strength can be improved temporarily after a short period of paired stimulation between the brain (motor cortex) and the peripheral nerves serving target muscles - in other words, "Fire Together, Wire Together". The brain's intention to move a muscle can be read by recording surface electrical activity over target muscles (electromyography or EMG). In animal models of SCI, scientists have successfully used target muscle EMG to trigger spinal cord electrical stimulation pulses while the animals perform physical exercises. Using the body's own signals to trigger nerve stimulation is called "closed-loop stimulation". This might be an optimal method to coordinate brain and nerve activity, especially with the clinical advantage of being possible to combine with physical exercise training. However, whether EMG-triggered closed loop stimulation has the same amount of effect when applied non-invasively in humans is still unknown. This proposed study is a proof-of-principle to demonstrate the potential of non-invasive closed-loop stimulation in humans with incomplete cervical SCI. We will test different combinations of triggered and non-triggered electrical and magnetic stimulation, and record the short-term effects on nerve transmission and skilled function of hand muscles. This pilot study will be a foundation for future studies combining EMG-triggered stimulation with long-term physical exercise training.
Most spinal cord injuries (SCI) are anatomically incomplete - some nerve circuits remain intact, even if the individual cannot feel or control them. Activating spared nerve circuits may improve functional recovery. With this goal, the Investigators have developed a form of electrical stimulation over the cervical spinal cord that can activate muscles in both hands simultaneously and comfortably. This technique, called cervical electrical stimulation (CES), works at the skin surface - no surgery or other invasive procedures are required. The long-term goal is to use CES to strengthen residual circuits to hand muscles after SCI. Regaining control over hand function represents the top priority for individuals with cervical SCI. In the current study, the Investigators first need to better understand how CES works. In the first half of this study, the Investigators will take a systematic approach to determining how CES interacts with other circuits in the spinal cord and the brain. In the second half of the study, the Investigators will test combinations of CES with active hand and wrist movements to find ways to enhance physical movement with CES. These experiments will improve understanding of electrical stimulation in SCI, and may set the table for future treatments to prolong any short-term benefits observed in this study.
Veterans are at higher risk than non-Veterans of falling ill with amyotrophic lateral sclerosis (ALS). ALS causes degeneration of motor neurons in both the brain and the spinal cord. Evidence from studies in people with spinal cord injury suggests that activating spared nerve circuits with electromagnetic stimulation improves nerve transmission. With this goal, the investigators have developed a novel method of noninvasive cervical (neck) electrical stimulation (CES). In this study, the investigators will investigate CES for its potential to strengthen nerve circuits to the hands in ALS. To the investigators' knowledge, electrical spinal stimulation for ALS has never been tested previously. This study will be performed in two stages: First, basic experiments will be performed to better understand how CES interacts with other types of electrical and magnetic stimulations over the brain and peripheral nerves. Second, experiments will be performed to determine the types of CES that can facilitate active arm and hand movements. These experiments will improve understanding of electrical stimulation in ALS, and may set the table for future treatments. Both United States Veterans and non-Veterans are eligible to participate in this study.
Pain after surgery is unavoidable, and opioid medications are the cornerstone of most pain management regimens. However, they come at a cost with profound impacts on gastrointestinal motility, respiratory depression, and even long-term dependence. Stimulating the external ear with cutaneous electrical current is similar to acupuncture and could help improve postoperative pain. The Bridge device (manufactured by Key Electronics \[Jeffersonville, IN, USA\] and distributed by Innovative Health Solutions \[Versailles, IN, USA\]), has been used with success in treating opioid withdrawal and in animal studies has shown increases in pain thresholds. The investigators propose a prospective, randomized, placebo-controlled, double-blinded trial to evaluate if auricular neurostimulation improves postoperative pain and reduces opioid requirements for patients undergoing elective colon surgery. pain perception in post-operative patients may be modulated via the auricular branch of the vagus nerve. This has the potential to reduce the use of opioid medications, which will in turn reduce the incidence of postoperative ileus and reduce patient need for and dependence on narcotic pain medications. This would have an enormous economic impact due to decreased length of hospital stays for patients who undergo abdominal surgery. In addition, opioid reduction could potentially lessen the national crisis of opioid addiction.
The purpose of this study is to determine if electric stimulation to the leg, called transcutaneous tibial nerve stimulation (TTNS), can improve bladder outcomes in acute spinal cord injury.
Determine the safety, feasibility, compliance, and efficacy of a daily home TTNS protocol in chronic SCI provided by self or caregiver for 4 weeks.
The purpose of this research study is to evaluate the effects upon the bladder of electric stimulation of the leg's tibial nerve in people with acute spinal cord injury with an intervention called transcutaneous tibial nerve stimulation (TTNS).
