92 Clinical Trials for Various Conditions
During this pilot study, the investigators will examine the effects of whole-body electrical muscle stimulation exercise (WB-EMS Exercise) on motoneuronal activation in healthy adults, which typically decreases with age. The investigators will also test whether WB-EMS Exercise will improve measures of physical function. Participants will undergo clinical and electrophysiologic testing before and after the WB-EMS Exercise intervention. The WB-EMS Exercise intervention will be delivered two times per week for four weeks. The hypothesis is that whole-body electrical muscle stimulation combined with physical exercise (WB-EMS Exercise) could bypass the problem of insufficient motoneuronal activation to improve exercise effect in older adults.
During this pilot study, the investigators will examine the effects of whole-body electrical muscle stimulation exercise (WB-EMS Exercise) on neuromuscular junction (NMJ) transmission and fatigability in adults with Generalized Myasthenia Gravis (gMG). The investigators will also test whether a relationship exists between NMJ transmission dysfunction and fatigability in gMG, which has long been presumed but never directly assessed. Participants will undergo clinical and electrophysiologic testing before and after the WB-EMS Exercise intervention. The WB-EMS Exercise intervention will be delivered 2 times per week for 4 weeks. Long-term follow up is optional. The hypotheses are (a) that the WB-EMS exercise will improve fatigability and NMJ transmission, and (b) that NMJ transmission dysfunction is related to fatigability.

Multi-center, three-arm, randomized, evaluator-blinded study of electrical muscle stimulation (EMS) and/or 1064 nm diode laser, pulsed electromagnetic field (PEMF) and vacuum assisted radio frequency (RF) using the Venus Bliss Max for fat reduction, body contouring and aesthetic improvement.
Some blood, bone marrow, and lymphatic (hematologic) cancers such as Hodgkin/Non-Hodgkin lymphomas, chronic lymphocytic leukemia, and multiple myeloma, are over-represented in Veterans due to exposures including Agent Orange and an increased percentage of patients of African American ethnicity. Hematologic transplantation (HCT) is a common treatment for these cancers, but often leads to deconditioning, fatigue, muscle atrophy, and poor quality of life, which are associated with complications such as hospitalization and infection. Despite the significance of these symptoms, there are no approved treatments to prevent/reverse these long-term effects. The cancer itself, side effects of chemotherapy, and sedentary behavior, contribute to these effects. Although exercise before and after HCT has helped reduce these effects, it is inconsistently recommended to patients and most remain sedentary through and after treatment. The investigators are testing an alternative exercise strategy, neuromuscular electrical stimulation, to maintain physical function quality of life after HCT.
A total of at least 15 and up to 17 healthy subjects at a single site, aged 25-45 years old, who wish to receive a lifting effect and improved muscle definition, will be included in the study. The procedure will include treatments with the Legend Pro™ DMA™ technology. Photos will be obtained at pre-defined time points throughout the study.

An investigation into the relative effectiveness of thermal-aided muscle stimulation vs. body temperature muscle stimulation for eliciting muscle contraction in the quadriceps
The two hypotheses to be tested in this study are that: 1. The administration of transcutaneous electrical muscle stimulation (TCEMS) after completion of conventional exercise training in pulmonary rehabilitation (PR) will result in further improvements in exercise tolerance, functional status and symptoms of patients with stable chronic obstructive pulmonary disease (COPD) above those achieved in PR alone. 2. TCEMS can improve exercise tolerance, functional status and symptoms even among COPD patients who fail to make gains in exercise tolerance by participating in conventional PR due to their debilitation and/or marked cardio-respiratory impairment.
The purpose of this study is to determine the feasibility of using extrinsic laryngeal muscle stimulation to elevate the larynx in a manner similar to that which occurs during normal swallowing. This research will also determine whether laryngeal elevation will open the upper esophageal sphincter to assist with entry of the bolus into the esophagus. This protocol includes studies in normal volunteers and patients with swallowing disorders. The outcome of this study will be relevant to future use of neuromuscular stimulation for laryngeal elevation in patients with pharyngeal dysphagia....
Open-label, baseline-controlled, multi-center study evaluating an electrical muscle stimulation system for circumferential reduction and muscle toning.

Follow Up Visits planned for 2, 30- and 90-days post treatment. Measurement outcomes will be compared to baseline.
Every patient admitted to the Intensive Care Unit (ICU) is at risk of developing "Intensive Care Unit Acquired Weakness" (ICUAW). ICUAW is associated with increased rate of mortality, prolonged duration of mechanical ventilation, ICU and hospital stay, rehabilitation time, and reduced quality of life. Currently, there is no effective treatment for ICUAW. Health Discovery Labs is conducting a research study to evaluate the safety of using an innovative experimental medical device in ICU settings that could mitigate ICUAW. This study is meant to demonstrate whether this new device interferes with standard ICU monitors.

The 12-week treatment programme will be completed by the subjects at home with treatment with the device in accordance with the device Instructions for Use.
The purpose of this project is to compare three treatment regimens for knee injury to the standard rehabilitation protocol: 1) NMES, 2) graduated strength walking (via a weighted vest), and 3) NMES combined with graduated strength walking. Each treatment arm will be supplemented by the standard of care and compared to a group who receive the standard rehabilitation only. The Study will compare the effects of NMES, Strength Walking and combined NMES/ Strength Walking on strength, mobility, symptomatology, and Quality of Life (QOL) in military members with knee injury to a standard rehabilitation protocol program only. All groups will participate in standard rehabilitation protocol. The groups will be assessed over 18 weeks to compare main and interactive effects over time.
The goal of this clinical trial is to learn if transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (DLPFC) can impact muscle fatigue. The main questions it aims to answer are: 1. Does tDCS of the left DLPFC increase the time that a fatiguing contraction can be maintained? 2. Does tDCS of the left DLPFC decrease the rate of increase of muscle activity, force error, and standard deviation of force during a fatiguing contraction. Researchers will compare tDCS of the left DLPFC to a SHAM stimulation (a type of stimulation that feels like real tDCS but does not elicit physiological effects) to see if tDCS of the left DLPFC works to reduce the progression of muscle fatigue. Participants will: Performing two experimental sessions held 3-10 days apart (usually 7 days) Perform a 9 hole pegboard test, maximum voluntary contractions, and a fatiguing contraction.
The goal of this clinical trial is to examine the effects of 12 weeks of post-operative use of a novel wearable electrical stimulation knee sleeve device (KneeStim) on post-operative biomechanical function (gait). Participants will be United States Military Academy cadets aged 17-27 years. The main questions it aims to answer are: * Examine the effects of KneeStim wear on cadets' post-operative gait * Examine changes in site-specific skeletal muscle mass * Examine the changes in patient-reported outcomes * Assess time to return to full duty * Compare Bioelectrical Impedance Analysis (BIA) measurements to Magnetic Resonance Imaging (MRI) measurements (total thigh volume) * Determine the concurrent criterion validity of the KneeStim device compared to gold- standard metrics (3D Motion Capture) Participants will undergo body composition analysis, MRI, strength testing, standard of care rehabilitation, gait analysis, and complete surveys. Participants will wear the KneeStim during their standard of care rehabilitation visits for the first 5 weeks post-operative, and throughout daily tasks from 6-12 weeks. Researchers will compare a control group (standard of care + KneeStim controlled low intensity) to an experimental group (standard of care + KneeStim flexible intensity) to assess the aims previously mentioned..
The investigators are studying a new rehabilitation treatment for individuals trying to recover walking after spinal cord injury (SCI). The investigators will test conditions in the blood and spinal fluid to determine the best time to start this new training program. This will include checking for certain features called biomarkers by testing participants' spinal fluid and blood and compare these features to individuals without SCI. These features will help investigators determine when to start the new training program, either right away or waiting for 3 months. The new training program uses walking downhill on a slight slope on a treadmill while muscles that are not working normally are stimulated to contract using low levels of electricity. Adding this stimulation will allow people to practice walking and other skills even though full muscle control has not recovered. This new program will be in addition to any other rehabilitation therapy and will not replace standard rehabilitation. The hope is to see if downhill training with muscle stimulation, when delivered at the most ideal time, will improve trunk and leg movement, walking, and overall function. This recovery of movement and function will be compared to people with SCI receiving standard rehabilitation alone. Certain regions of the brain and spinal cord will also be studied using MRI scans to determine if these are affected by the training and compare to individuals without SCI. The total length of the study for SCI participants will be up to 16 weeks if in the standard of care group and up to 33 weeks if in the trained group. Healthy control participants will be involved for 1-2 visits.

Bariatric surgery is an effective treatment for severe obesity but results in loss of muscle mass. The investigators will test the hypothesis that consumption of an Essential Amino Acid-based nutritional formulation will maintain muscle mass while stimulating fat loss after bariatric surgery.
Each year, an estimated 34,000 individuals undergo epidural spinal cord stimulation (SCS) surgery to address debilitating chronic low back and leg pain (CLBLP). Although the commercial application of SCS to treat CLBLP was approved by the FDA in 1989, only in the past decade have significant advancements in stimulator technology been introduced. For instance, traditional SCS devices achieved reduction in pain using a type of stimulation known as low-frequency tonic stimulation (LFTS, below 100 Hz), which was dependent on induction of paresthesias (i.e., a tingling sensation) over the areas of pain perception. However, investigators now know that LFTS compromises sensory information flowing back to the spinal cord, which can be important in other spinal cord functions such as proprioception and movement. On the other hand, recent innovations in stimulator technology now provide the capability to apply stimulation frequencies up to 10,000 Hz along with complex waveform patterns - known as high frequency burst stimulation or HFBS - that can mitigate pain perception without the induction of paresthesias and the negative consequences on proprioception and movement. We propose to study the effects of these recently introduced features in SCS technology on motor and sensory spinal thresholds, proprioception and movement in subjects with CLBLP. The spinal cord relies on input from the motor cortex and surrounding extremities to initiate specific muscle recruitment, and recent evidence suggests that preservation of temporally specific proprioceptive information via dorsal column primary afferent fibers is critical for natural motor behaviors such as ambulation. Since the spinal cord is exposed during the placement of the SCS device, information about a subject's motor and sensory spinal pathways can be easily obtained during the regular course of the procedure and compared to proprioceptive and motor responses once the subject is awake and moving with the device turned on. Our lab specializes in electrophysiological recordings in subjects undergoing spinal cord stimulator (SCS) implantation for CLBLP, while MUSC's Locomotion Laboratory specializes in quantifying proprioception and movement in human subjects. In this proposal, investigators will apply these techniques to subjects with CLBLP to determine effects of spinal neuromodulation on motor and sensory thresholds, proprioception, and kinematics.
