Filter by:Chemotherapy-induced peripheral neuropathy (CIPN), a side effect of antineoplastic medication, was reported to occur in about 68% of the patients receiving chemotherapy. CIPN does not only limit quality of life due to neuropathic symptoms but also may lead to dose reductions or premature interruption of therapy and thus to suboptimal cancer treatment. Patients with neuropathy suffer from sensory disturbances as tingling, numbness, burning pain or sleep disturbances and even though numerous drugs are available, it is still difficult to sufficiently control these Symptoms. High tone therapy / high tone external muscle stimulation (HTEMS) seems to be an effective treatment for neuropathic symptoms. Previous studies observed promising results in diabetics and chronic kidney disease (CKD) patients. To date, there is no investigation on HTEMS in patients with chemotherapy induced neuropathy. Therefore, this aim of this project is to test if HTEMS would bring about a stronger decrease in neuropathic symptoms in this specific patient group, compared to a placebo treatment. The primary objective is the alleviation of paresthesias. The secondary objective focuses on detailed symptoms of neuropathiy as well as on health-related quality of life.
The goal of this observational study is to characterize the standardized stimulation parameter for noninvasive, transcutaneous, repetitive phrenic nerve electrical stimulation. The main questions it aims to answer are: - Is the phrenic nerve repetitive electrical stimulation test feasible for use as non-invasive transcutaneous electrical stimulation? - What is the most optimal stimulation parameters for repetitive phrenic nerve electrical stimulation in healthy adult populations in terms of effective and safe activation of diaphragm?
High-frequency alternating currents of greater than 1 kHz applied on peripheral nerves has been used in animal studies to produce a motor nerve block. It has been evidenced that frequencies higher than 5 kHz are necessary to produce a complete peripheral nerve block in primates, whose nerve thickness is more similar to humans.
In this study, the effects of the external electrical stimulation (EES) added to pelvic floor muscle training (PFMT) on stress urinary incontinence (SUI) were investigated.
To reveal the effects of Neuromuscular Electrical Stimulation (NMES) applied over the thigh on incontinence symptoms, pelvic floor muscle function, bladder function, quality of life and sexual function in women with urge urinary incontinence (UUI) symptoms. Our goal is to contribute to the literature on electrical stimulation (ES) applications used in UUI treatment. Female patients aged 18-65 years with UUI symptoms will be included in the study. Patients will be divided into 2 groups randomly. The first group will be given Neuromuscular Electrical Stimulation (NMES) and lifestyle suggestions (LSS) (NMES group). The second group will be given sham NMES in addition to LSS (SHAM ES group). Information about bladder irritants, voiding posture and behavior, weight control and pelvic floor muscle training will be provided in the LSS. ES applications will be performed 3 days a week for 30 minutes per session for 8 weeks. All participants will be evaluated pretreatment, after the 4th week and posttreatment. Pelvic floor muscle function will evulate with the Modified Oxford Scale. In addition, women's bladder function with the urinary diary for 3 days, incontinence symptoms with the International Incontinence Consultation Questionnaire-Short Form (ICIQ-SF) and the Coital Incontinence Score (CIS), quality of life with the King Health Questionnaire (KHQ) and Sexual Function will be evaluated with Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). At the end of the 8th week, both the Subjective perception of improvement and treatment satisfaction of the patients will be questioned
Low-frequency percutaneous electrical stimulation is the application of an electrical current of <1000Hz through acupuncture needles located on the epineurium of the peripheral nervous system. The hypothesis is that by placing the electrode, needle, closer to the nerve, a greater stimulation of the same will be achieved, thus being able to obtain greater effects. The goal is to determine if this technique has any effect on grip strength in the short term.
Overactive bladder (OAB) is a symptom complex defined as urgency, with or without urge urinary incontinence (UUI), usually with frequency and nocturia, in the absence of urinary tract infection. Currently, a wide range of therapeutic options exist for the treatment of OAB. These include first-line conservative (physical) therapies which focus on electrical stimulation (ES) and behavioral therapies such as lifestyle modifications, bladder training (BT), pelvic floor muscle training with or without biofeedback, second-line therapies which are pharmacologic, and third-line therapies which either neuromodulate or chemodenervate the bladder. In clinical practice, BT and Intravaginal ES (IVES) are frequently used together in the treatment of women with OAB, but the evidences/results of the combined (BT+IVES) use of these two treatment options are so rare that they can be neglected in the literature. There is only one study including BT+ES treatment arm (one of the four treatment arms) in women with idiopathic OAB in the literature. In a study, BT+ES was not found to be effective both from BT alone and from the untreated control group. While interpreting the results of this study, it should be take into consideration that patients treated received relatively few treatment sessions (nine treatment sessions, once weekly) in this study. In addition, in the light of authors clinical experience, the investigators think that this issue is still open for research. Moreover, there is no recommendation on conservative combinations in the guidelines due to insufficient data. This study is the first prospective randomized controlled trial that compares the efficacy of BT and BT plus IVES in women with idiopathic OAB. In this study, the investigators aimed to evaluate the efficacy of BT with and without IVES on incontinence-related QoL and clinical parameters in women with idiopathic OAB.

Introduction: Neuromuscular electrical stimulation (NMES) has the purpose of generating muscle contractions to minimize muscular atrophy and to improve neuromuscular performance. NMES has been performed using monophasic or biphasic currents, applied over a nerve trunk or muscle belly, and both can generate contractions by the peripheral and central nervous system. Pulse width (wide or narrow) is an essential parameter for NMES. Although NMES studies using wide pulses have been performed with monophasic currents, it is known that this current induces discomfort during NMES. Therefore, it is necessary to analyze if biphasic currents have the same effect as monophasic currents using the same parameters. Objectives: To compare the effects of NMES with narrow and wide pulse widths associated with monophasic and biphasic currents, applied over a tibial nerve and triceps surae muscles in healthy individuals in terms of muscle fatigue, central and peripheral contribution, voluntary and evoked force and sensory discomfort. Methods: A crossover, experimental controlled and randomized study will be developed with healthy male and female (age: 18-45 years). The following dependent variables will be: amplitude of H-reflex and M-wave (single and double pulses), voluntary and evoked triceps surae muscles torque, fatigability (force time integral), perceived discomfort and neuromuscular adaptations. The independent variables will be related to current phase, pulse width and location of electrical stimulation electrodes. There will be a familiarization session followed by 9 sessions with 7 rest days between them (10 weeks). Data will be reported as mean and standard deviation (± SD). Parametric tests will be used for the normally distributed data (Shapiro-Wilk test) that show homogeneous variations (Levene test). A repeated measure mixed-model ANOVA will be performed and, in the case of major effects or significant interactions, the Tukey post-hoc test will be applied. In addition, the power and size of the effect (reported as partial eta square, partial η2) will be calculated. The significance threshold will be set at p <0.05 for all procedures. Expected results: Biphasic currents will be more comfortable and will generate less muscle fatigue when compared to monophasic currents. There will be less fatigue and greater central contribution when wider pulse currents will be applied over a nerve trunk concerning the application with a wide pulse over a muscle belly.
The aim of the study is to evaluate effects of current stimulation of the brain on vision parameters, vision-related quality of life, and physiological parameters to uncover mechanisms of vision restoration. These include EEG-spectra and coherence measures, and visual evoked potentials. The design of stimulation protocols involves an appropriate sham-stimulation condition and sufficient follow-up periods to test whether the effects are stable. This is the first application of non-invasive current stimulation for vision rehabilitation in stroke-related visual field deficits.
