OBJECTIVE To compare the effect of cyclic and electromyography (EMG)-triggered electrical stimulation on motor impairment and function of the affected upper extremity in chronic stroke. DESIGN Randomized controlled trial. SETTING Outpatient clinic of a rehabilitation centre. SUBJECTS AND INTERVENTION Twenty-two subjects in the chronic stage after stroke were randomly assigned to receive e...

Electrical signals have been applied towards the repair of articular tissues in the laboratory and clinical settings for over seventy years. We focus on healing of the meniscus, a tissue essential to knee function with limited innate repair potential, which has been largely unexplored in the context of electrical stimulation. Here we demonstrate for the first time that electrical stimulation en...

OBJECTIVE Electrical stimulation is a widely used and effective tool in systems neuroscience, neural prosthetics, and clinical neurostimulation. However, electrical artifacts evoked by stimulation prevent the detection of spiking activity on nearby recording electrodes, which obscures the neural population response evoked by stimulation. We sought to develop a method to clean artifact-corrupted...

This review discusses the advancements that are needed to enhance the effects of electrical stimulation for restoring or assisting movement in humans with an injury/disease of the central nervous system. A complex model of the effects of electrical stimulation of peripheral systems is presented. The model indicates that both the motor and sensory systems are activated by electrical stimulation....

BACKGROUND AND PURPOSE Gait rehabilitation in patients with severe hemiplegia requires substantial effort. Preliminary studies indicate potential beneficial effects of using multichannel functional electrical stimulation (MFES) for gait rehabilitation in these patients. In this study, a new method of gait rehabilitation for nonambulatory patients with hemiplegia by means of MFES added to conven...

After stroke, up to 81% of individuals develop shoulder subluxation, a condition frequently associated with poor upper limb function. Recently, electrical stimulation has been applied to shoulder muscles to treat shoulder subluxation. The purpose of this meta-analysis was to examine the efficacy of surface electrical stimulation for the prevention or reduction of shoulder subluxation after stro...

BACKGROUND A randomized clinical has shown the effectiveness of intramuscular electrical stimulation for the treatment of poststroke shoulder pain. OBJECTIVE Identify predictors of treatment success and assess the impact of the strongest predictor on outcomes. METHOD This is a secondary analysis of a multisite randomized clinical trial of intramuscular electrical stimulation for poststroke ...

Electrical stimulation of the L-3,4 dermatome during treadmill walking is proposed as a gait training modality in incomplete spinal cord injured patients. The dermatome stimulation proved to be efficient in diminishing the extensor tone occurring after loading of the paralyzed limb during the stance phase of walking and resulting in improved flexion of the leg during the swing phase.

It has been known that monkeys will repeatedly press a bar for electrical stimulation in several different brain structures. We explored the possibility of using electrical stimulation in one such structure, the nucleus accumbens, as a substitute for liquid reward in animals performing a complex task, namely visual search. The animals had full access to water in the cage at all times on days wh...

In the wound healing research, the exact mechanism of action of different modalities of electrical stimulation (ES) remains controversial and unresolved. In this study we discuss a particular ES, with a different type of waveform, corresponding to the principle of stochastic resonance. Between July 2008 and May 2010, 32 patients were enrolled and ES was applied to wounds using the bioelectrical...
