Summary: A novel machine-learning-based FES control algorithm was proposed in this study to enhance gait rehabilitation in post-stroke hemiplegic patients. The system controlled electrical stimulation via deep neural networks trained using muscle activity data from healthy people during gait, and was tested with healthy human subjects in comparison with a conventional FES control method.

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: The study revealed that female athletes in the premenstrual phase (PMP) showed accentuated impairment in postural control after exercise, with lower results in isometric maximal voluntary contraction and Y-balance test, and a more significant increase in center of pressure sway area and length compared to other menstrual cycle phases.

Summary: The purpose of this study was to evaluate the performance of healthy young adults using functional jump tests and static posturography control under pre-and post-fatigue conditions of the ankle invertor and evertor muscles. Results showed a decrease in performance in functional activities and postural control under all conditions after the induction of muscle fatigue, except for the speed at a bipedal stance with eyes open.

Summary: Percutaneous electrical stimulation is a method used to improve functional capabilities in older individuals. The specific physiological needs of the individual determine whether neuromuscular electrical stimulation (NMES) or sensory electrical stimulation (SES) is most appropriate. NMES enhances muscle strength and motor output, while SES facilitates sensorimotor activity.

Summary: This study investigated the fatigue reducing ability of spatially distributed sequential stimulation (SDSS) in functional electrical stimulation (FES)-rowing. The results showed that SDSS significantly reduced fatigue and lengthened the rowing time by approximately 30%. The study demonstrated that the application of SDSS could enhance the effectiveness of FES-rowing as a rehabilitative exercise.

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 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: Functional electrical stimulation (FES) is a potential neurorehabilitative intervention for enabling functional movements in individuals with mobility impairments. This study proposes the use of ultrasound imaging-derived echogenicity signal as an indicator of FES-induced muscle fatigue. The experimental results show a strong relationship between the ultrasound-derived signal and muscle fatigue under isometric and dynamic muscle contraction conditions.

Summary: The purpose of this study was to investigate the effect of transcranial alternating current stimulation (tACS) on the time to task failure (TTF) in a precision grip task. The results showed that tACS did not increase the TTF during fatiguing contractions in young adults.

Summary: The study found that sequential stimulation (SEQ) can effectively reduce neuromuscular fatigue, but its adoption in research and clinical settings is limited. By using the SEQ adapter, signal integrity can be preserved, effectively increasing the utilization of SEQ in existing rehabilitation paradigms.

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: The study found that both unilateral and bilateral fatiguing exercises led to increased sway velocity and total displacements, while bilateral fatiguing exercises resulted in early anticipatory onset of TrA/IO and increased co-activation index of the TrA/IO-LMF muscle pair during the CPAs phase. The results suggest that repetitive unilateral or bilateral fatiguing exercises may differently affect the anticipatory component of postural control.

Summary: The aim of this study was to investigate sex differences in postural control changes and muscle plasticity with ankle muscle fatigue during a standing forward leaning task. The results showed no significant differences between males and females in postural control changes and muscle plasticity.
