Summary: This study investigated the effects of different neck flexion angles on neck gravitational moment and muscle activity of smartphone users who stand. The results suggest that maintaining a 0-degree neck flexion angle can reduce muscle activity and neck discomfort, avoiding an increase in neck gravitational moment.

Summary: The single-leg heel raise test showed similar performance in young males and females, but was not suitable as a clinical assessment of maximal plantar flexion strength. It is better suited for evaluating the fatigability of dynamic lower extremity contractions. The reduction in maximal strength at task failure was associated with decreased neural drive to the plantar flexor muscles.

Summary: Soft exosuits are emerging robots that reduce the metabolic cost of human movement. Most research focuses on walking and running, while little attention has been given to stair climbing. This paper presents a waist-wearable soft exosuit that assists hip flexion during stair climbing and demonstrates its effectiveness in reducing metabolic consumption and muscle fatigue.

Summary: Polymer Optical Fiber (POF) and Cyclic Transparent Optical Polymer (CYTOP) based sensors have advantages in terms of light weight, flexibility, and reduced dimensionality for applications in assistive robotics. A fatigue test was performed on three Polymeric Optical Fiber sensors for angle measurement, and it was found that the CYTOP sensor did not break during the trial. However, it is more sensitive to light variations in the environment compared to the other two sensors, which ruptured after approximately 70 minutes and 8,360 cycles.

Summary: This study examined the fatigue of antagonist muscles during a low-force isometric contraction. The results suggest that antagonist muscles may experience peripheral fatigue during prolonged low-force isometric fatiguing contractions. Additionally, changes in coactivation activities are influenced by both central neuronal mechanisms and peripheral metabolic factors.

Summary: This study aimed to investigate the acute effects of officiating a football match on isometric knee flexion strength and passive hip flexion range-of-motion in referees and assistant referees. The results showed that officiating a match led to a decrease in isometric knee flexion strength in the non-dominant limb of referees, while no significant changes were observed in assistant referees. Additionally, there were no significant differences in hip flexion range-of-motion in assistant referees before and after the match.

Summary: This scoping review explores the relationship between technology, fatigue, and health care to improve conditions for providers. The study found that video and electronic health record use can lead to physical and emotional fatigue, as well as other behavioral impacts. It suggests that health care systems need to evaluate the impact of technology on providers' well-being and prevent fatigue and burnout.

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 skeletal muscle deconditioning and reduced exercise capacity occur early during chemotherapy for breast cancer. These changes occur within the first 8 weeks of treatment and do not further decrease after chemotherapy. The study also showed that cancer-related fatigue and quality of life are impaired after the start of chemotherapy, while physical activity level remains stable.

Summary: ACL deficiency can lead to knee joint instability, requiring surgery or activity modification for recovery; research has found that knee flexion angle and muscle force activations have a significant impact on the stability of ACL-deficient joints and can be evaluated using specific parameters.

Summary: The study found that age does not significantly affect muscle activity variability, oxygenation, or thickness, but there are some correlations between different age groups, such as a stronger relationship between muscle variability and oxygenation in young females.

Summary: A facile fluorescence probe BQBH was synthesized and investigated on its spectrum property. The BQBH showed high sensitivity and selectivity for Cd2+ with the lowest detection of 0.14 μM. The 1:1 binding ratio between BQBH and Cd2+ was confirmed by various analyses, and its applications in test paper, smart phone, and cell image were also studied.
