Summary: This study aimed to investigate the changes in muscle architecture of quadriceps femoris constituents with sensor electrodes placed over VL and VM motor points during a neuromuscular electrical stimulation session. The results showed no difference in the muscle architecture changes when the electrodes were placed on VL and VM motor points. Therefore, clinicians can choose either VL or VM motor points for sensor electrode positioning and expect similar muscle architecture adaptation.

Summary: This article presents a novel electromyography (EMG)-driven exoneuromusculoskeleton that integrates the neuromuscular electrical stimulation (NMES), soft pneumatic muscle, and exoskeleton techniques, for self-help upper limb training after stroke. The developed system provides significant improvement in limb performance and muscular coordination, supporting self-help upper limb rehabilitation after stroke.

Summary: The effects of unilateral chronic electrical stimulation on the neuromuscular junction (NMJ) were investigated in rats exposed to long-term post-synaptic neuromuscular blockade. The study found that stimulation reduced axonal and glial sprouting at the NMJ, likely due to the release of muscle-derived myokines.

Summary: The study found that under submaximal contraction level, PC is more effective than AC in generating muscle fatigue, while there is no significant difference in discomfort level between the two.

Summary: This study aimed to compare the performance and fatigability between young, old, and very old men during isometric, concentric, and cycling tasks. The results showed that the performance of old and very old men was lower than that of young men in all tasks, with the difference being most significant in the cycling task. Overall, old and very old men presented similar levels of force loss, alterations in voluntary activation, and twitch amplitude.

Summary: This study focuses on restoring arm and hand control in paralyzed individuals using spinal cord stimulation. By stimulating specific spinal segments, sustained arm movements were produced, allowing monkeys with paralysis to regain the ability to reach and grasp within a few days after injury.

Summary: This study found that fatigue in the dominant shoulder affects movement in the contralateral upper limb, which may increase the risk of shoulder pain.

Summary: This study investigated the effects of electrical pulse stimulation (EPS)-evoked muscle contraction on irisin and CTSB secretion in 3D-engineered muscle (3D-EM). The results showed a significant increase in irisin secretion following EPS, while no significant difference was observed in CTSB secretion between the two groups. Irisin may be a contractile muscle-derived myokine, but CTSB is not secreted by EPS-evoked muscle contractile stimulation in 3D-EM.

Summary: This study compared NMES and PNS in terms of fatigue performance and peripheral contribution to voluntary force capacity. While both induced force reductions, NMES led to changes in myoelectrical activity suggesting performance fatigability, whereas PNS did not. This suggests PNS recruits a wider pool of muscle fibres and motor units, making it a favorable alternative for rehabilitation.

Summary: This study compared the effects of voluntary and electro-induced warm-up on balance control. The results showed that voluntary warm-up immediately improved balance control and lasted for at least ten minutes, while electro-induced warm-up required some recovery time to produce its improving effects.

Summary: This study utilized high-frame-rate ultrasound images to assess muscle fatigue induced by NMES, providing a new method to observe the contractility of targeted muscles. By investigating the correlation between strain maps and force values, the study found patterns in muscle contractility changes. Additionally, a novel methodology based on PCR was proposed to explore the correlation between strain and force.

Summary: The novel whole-body neuromuscular electrical stimulation can be safely applied in healthy subjects without adversely affecting blood fluidity. Hybrid exercise with ergo-bicycle can significantly increase oxygen intake compared to cycle ergometer exercise, without adversely affecting microvascular flow in vivo.

Summary: This study investigates how modulating cocontraction of antagonist muscles during functional electrical stimulation (FES) can impact reaching performance and energy usage. The results suggest that dynamically modulating limb stiffness can significantly improve energy usage and movement performance. Therefore, brain-controlled FES becomes a more viable option for restoration of reaching after paralysis.

Summary: This study aimed to evaluate the immediate clinical effects of superimposing EMS on strength training compared with conventional exercise in healthy non-athletic adults. The results showed that EMS was more effective in stimulating muscle contractions compared to conventional training. This suggests that EMS may be a safe and reasonable modality for improving physical fitness in healthy individuals.

Summary: This study investigated the acute effects of fatiguing exercise on postural control in athletes practicing symmetric and asymmetric sports. The results showed a significant fatigue effect on both dominant and non-dominant legs, with a tendency for a more pronounced impact on athletes practicing asymmetric sports on the dominant leg.
