Early mobilization strategies in the intensive care unit may result in the prevention and reduction of polyneuromyopathy in the critical patient, improved quality of life, shortened ICU and hospital stay, and lesser mortality during hospitalization. However, it is well known that factors such as the protocol used, the population included in the studies, the timing of the strategy, the severity of the patients and different barriers directly influence the outcomes. This study examines the main protocols described in the literature and their associated results...

Rehabilitation method of motor dysfunction is a challenging issue of neural rehabilitation. Neuromuscular electrical stimulation (NMES) has been frequently used in rehabilitation therapy to improve neural recovery such as stroke and spinal cord injury. Stimulus, acting on sensorimotor neural system components, resulted in the increased cortical excitability which accompanied with motor performance improvement. Stimulus information conveyed by sensory system included below four elementary attributes: modality, location, intensity, and timing...

The goal of this paper is to study the effects of supine and stand retraining (SRT) interventions with and without multi muscle neuromuscular electrical stimulation (NMES) on the neuromuscular EMG responses of the leg muscles for individuals with motor complete SCI during walking on a body-weight support (BWS) treadmill. The main outcome variables were EMG amplitude, integrated EMG and co-contraction indices (co-excitation and co-activation) collected during a 10-minute walking treadmill trial. Data was analyzed for the first, fifth and tenth minute of walking...

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder resulting from skeletal muscle weakness and fatigue. An early common symptom is fatigable weakness of the extrinsic ocular muscles; if symptoms remain confined to the ocular muscles after a few years, this is classified as ocular myasthenia gravis (OMG). Diagnosis of MG when there are mild, isolated ocular symptoms can be difficult, and currently available diagnostic techniques are insensitive, non-specific or technically cumbersome. In addition, there are no accurate biomarkers to follow severity of ocular dysfunction in MG over time...

The grasp reflex is a distressing symptom but the need to treat or suppress it has rarely been discussed in the literature. We report the case of a 17-year-old man who had suffered cerebral infarction of the right putamen and temporal lobe 10 years previously. Forced grasping of the hemiparetic left upper limb was improved after a unique combined treatment. Botulinum toxin type A (BTX-A) was first injected into the left biceps, wrist flexor muscles, and finger flexor muscles. Forced grasping was reduced along with spasticity of the upper limb...

Peripheral muscle dysfunction is an important systemic consequence of cystic fibrosis (CF) with major clinical implications, such as exercise intolerance and reduced quality of life. Evidence is now accumulating that lack of physical activity is unlikely to be the sole explanation for peripheral muscle dysfunction of patients with CF. Particularly, the demonstration of CFTR expression in both murine and human skeletal muscle suggests the potential implication of intrinsic CF-related factors. By combining data from both human and animal models, this review describes CF peripheral muscle abnormalities and critically reviews the advances in understanding the impact of the underlying mechanisms...

INTRODUCTION: Neuromuscular electrical stimulation (NMES) over a muscle belly (mNMES) recruits superficial motor units (MUs) preferentially, while NMES over a nerve trunk (nNMES) recruits MUs evenly throughout the muscle. We tested whether "interleaving" pulses between the mNMES and nNMES sites (iNMES) reduces the fatigability of contractions for people experiencing paralysis due to chronic spinal cord injury. METHODS: Plantarflexion torque and soleus electromyography (M-waves) were recorded from 8 participants...

Extensive literatures have shown approaches for decoding upper limb kinematics or muscle activity using multichannel cortical spike recordings toward brain machine interface (BMI) applications. However, similar topics regarding lower limb remain relatively scarce. We previously reported a system for training monkeys to perform visually guided stand and squat tasks. The current study, as a follow-up extension, investigates whether lower limb kinematics and muscle activity characterized by electromyography (EMG) signals during monkey performing stand/squat movements can be accurately decoded from neural spike trains in primary motor cortex (M1)...

BACKGROUND: Vascularized composite allografts, particularly hand and forearm, have limited ischemic tolerance after procurement. In bilateral hand transplantations, this demands a 2 team approach and expedited transfer of the allograft, limiting the recovery to a small geographic area. Ex situ perfusion may be an alternative allograft preservation method to extend allograft survival time. This is a short report of 5 human limbs maintained for 24 hours with ex situ perfusion. METHODS: Upper limbs were procured from brain-dead organ donors...

Antoine Langeard, Lucile Bigot, Nathalie Chastan, Antoine Gauthier
The lower limb muscle functions of the elderly are known to be preferentially altered by ageing. Traditional training effectively counteracts some of these functional declines but is not always accessible due to its cost and to the accessibility of the training centers and to the incapacities of some seniors to practice some exercises. Neuromuscular electrical stimulation (NMES) could provide an interesting alternative muscle training technique because it is inexpensive and transportable. The aim of this systematic review was to summarize the current evidence on the effect of the use of lower limb NMES as a training technique for healthy elderly rehabilitation...

Although commonly used, the physiological mechanisms underlying all-out exercise performance are still unclear and an in-depth assessment of skeletal muscle bioenergetics is lacking. Therefore, phosphorous magnetic resonance spectroscopy ((31)P-MRS) was utilized to assess skeletal muscle bioenergetics during a 5-min all-out intermittent isometric knee-extensor protocol in 8 healthy men. The metabolic perturbation, adenosine triphosphate (ATP) synthesis rates, ATP cost of contraction, and mitochondrial capacity were determined from intramuscular concentrations of phosphocreatine (PCr), inorganic phosphate (Pi), diprotonated phosphate (H2PO4⁻ ), and pH...
