neuromuscular electrostimulation

Intense pulsed electric fields (PEF) are a novel modality for the efficient and targeted ablation of tumors by electroporation. The major adverse side effects of PEF therapies are strong involuntary muscle contractions and pain. Nanosecond-range PEF (nsPEF) are less efficient at neurostimulation and can be employed to minimize such side effects. We quantified the impact of the electrode configuration, PEF strength (up to 20 kV/cm), repetition rate (up to 3 MHz), bi- and triphasic pulse shapes, and pulse duration (down to 10 ns) on eliciting compound action potentials (CAPs) in nerve fibers...

Background: Previous results of clinical studies suggest that neuromuscular electrostimulation (NMES) therapy, especially in combination with traditional dysphagia therapy, may be helpful in patients with neurogenic swallowing disorders. In these studies, repetitive application of a rectangular current impulse was used to increase muscle strength of the anterior neck. However, according to sports physiological findings, an increase of muscle strength can be better achieved by using different NMES stimulation protocols, e...

Neurological and neurophysiological knowledge of neuromuscular diseases is combined in neurolaryngology with experience from laryngology. Laryngeal electromyography (LEMG) is the most important diagnostic and prognostic tool in neurolaryngology. It can be combined with diagnostic electrostimulation. Interest in LEMG today extends beyond the thyroarytenoid muscle to all accessible laryngeal muscles. LEMG should be performed and interpreted according to a standardized protocol. Main applications of LEMG are confirmation, topodiagnostic and prognostic assessment of vocal fold paralysis...

Aim        To compare effects of neuromuscular electrostimulation (NMES) with various intensity of induced muscle contractions on its tolerance and effect on physical work ability in elderly patients admitted for chronic heart failure (CHF).Material and methods        The study included 22 patients older than 60 years admitted for decompensated CHF. NMES was performed from the 2nd or 3d day of stay in the hospital to the discharge from the hospital. Patients choose the stimulation regimen themselves based on the result of the first session: the high intensity to achieve maximum tolerable muscle contractions (group 1) or the lower intensity to achieve visible/ palpable muscle contractions (group 2)...

Type-2-diabetes mellitus (T2DM) is a global problem of medical, social and economic consequences. Physical activity is a vital therapy in patients with T2DM, but some of them cannot exercise for various reasons. The purpose of our pilot study was to determine whether a combination of neuromuscular electrostimulation (NMES) and insulin therapy could improve the management of T2DM patients with hemiplegia caused by an ischemic stroke. Fifteen immobile patients with T2DM on insulin therapy were enrolled in the study...

OBJECTIVE: Activation of the venous muscle pumps of the leg by intermittent transdermal neuromuscular stimulation of the common peroneal nerve has been previously shown to augment venous and arterial flow in patients with leg ulcers. This study aims to establish if microcirculation in the wound bed and periwound area are augmented by the activation of a neuromuscular electrostimulation device (NMES) (Geko, Firstkind Ltd., UK). METHOD: In this self-controlled, observational study, laser speckle contrast imaging was used to map and quantify microcirculatory flow in the wound bed and periwound area of patients with venous leg ulcers (VLU)...

Neuromuscular electrostimulation (NMES) has been used mainly as a method to promote muscle strength, but its effects on improving blood flow are less well known. The aim of this study is to deepen the knowledge about the local and contralateral effects of the application of symmetric biphasic square currents on skin temperature (Tsk). An experimental pilot study was developed with a single study group consisting of 45 healthy subjects. Thermographic evaluations were recorded following the application of NMES to the anterior region of the thigh...

Activation of the venous muscle pumps by neuromuscular stimulation of the common peroneal nerve has been previously shown to increase venous and arterial flow in the legs of healthy subjects. The aim of this study is to determine whether a similar effect is observed in patients with chronic venous leg ulcers. 1 Hz intermittent electrostimulation of the common peroneal nerve was applied to 14 patients with ulcers between 1 and 10 cm in diameter, eliciting a small, painless, regular, muscular twitch of the leg...

BACKGROUND: Neuromuscular electrical stimulator (NMES) devices increase blood flow to the lower limb by a process of intermittent muscular contraction initiated by a transdermal stimulus to the common peroneal nerve. However, its effects on localized microvascular blood supply to lower limb wounds are unknown. This study is a single-center open label study measuring the effect of neuromuscular stimulation of the common peroneal nerve on the microvascular blood flow within the wound bed of arterial leg ulcers...

INTRODUCTION: The prevalence of oropharyngeal dysphagia is high after a stroke. Clinically, it manifests as alterations affecting swallowing efficiency and safety, with the consequent morbidity and mortality associated with nutritional and respiratory alterations. AIM: To carry out an updated review of the diagnostic and therapeutic aspects of oropharyngeal dysphagia after a stroke that can be applied in daily clinical practice, and of the non-invasive neurostimulation techniques...

BACKGROUND: Total hip replacement is recognised as a major risk factor for deep vein thrombosis (DVT). The aim of this study was to investigate the feasibility of using a novel neuromuscular electrical stimulation device (NMES) for DVT prevention in patients recovering from elective hip replacement surgery. METHODS: Twenty-eight patients undergoing total hip replacement were randomised to receive postoperative treatment with either the NMES device or compression stockings continually from post-surgery until discharge (day 4)...

BACKGROUND: Unrecovered Bell palsy is difficult to treat, because until now in literature there is not a gold standard. This study aimed to evaluate the effectiveness of neuromuscular electrical stimulation (NMES) and shortwave diathermy (SWD) therapy for chronic Bell palsy. METHODS: After 5 months of conventional therapy, this 2-arm randomized controlled trial enrolled and randomly allocated 20 patients to a treatment group with NMES+SWD and supervised exercises (n = 10) or a sham group with supervised exercise alone (n = 10)...

BACKGROUND: Whether high-or-low intensity exercise coupled with neuromuscular electrostimulation (NMES) affect IGF-1 and IGFBP-1 is unknown. The scope of this study was to test whether 8-week high-intensity interval training (HIIT) and continuous aerobic training (CA) combined with/without NMES performed at 65% and 120% of VO2max on a cycle ergometer induce different metabolic adaptations. METHODS: A randomized controlled trial with a parallel groups study design was used...

Reduced mobility and physical independence of elders has emerged as a major clinical and public health priority with extended life expectancy. The impact of the neuromuscular function on muscle activity and properties has emerged as a critical factor influencing the progress and outcome of muscle changes with aging. However, very little is known about the neuromuscular junctions (NMJs) in humans, in part due to technical constraints limiting the access to healthy, fresh neuromuscular tissue. Here, we describe a method, called Biopsy using Electrostimulation for Enhanced NMJ Sampling (BeeNMJs) that improves the outcome of muscle biopsies...

BACKGROUND AND PURPOSE: The ankle plantarflexor muscles are the primary generators of propulsion during walking. Impaired paretic plantarflexion is a key contributor to interlimb propulsion asymmetry after stroke. Poststroke muscle weakness may be the result of a reduced force-generating capacity, reduced central drive, or a combination of these impairments. This study sought to elucidate the relationship between the neuromuscular function of the paretic plantarflexor muscles and propulsion deficits across individuals with different walking speeds...

PURPOSE: This study aimed at determining through MRI investigations, force and soreness assessments whether the modulation of muscle length is a relevant strategy for minimising neuromuscular electrical stimulation (NMES)-induced muscle damage in young healthy participants. METHODS: Comparison of 2 NMES sessions (40 isometric electrically-evoked contractions of the knee extensors) was randomly performed on 1 knee flexed at 50° (short muscle length) and the contralateral at 100° (long muscle length) in a single group of healthy participants...

BACKGROUND: We developed a brain-machine interface (BMI) system for poststroke patients with severe hemiplegia to detect event-related desynchronization (ERD) on scalp electroencephalogram (EEG) and to operate a motor-driven hand orthosis combined with neuromuscular electrical stimulation. ERD arises when the excitability of the ipsi-lesional sensorimotor cortex increases. OBJECTIVE: The aim of this study was to evaluate our hypothesis that motor training using this BMI system could improve severe hemiparesis that is resistant to improvement by conventional rehabilitation...
