Summary: Cutaneous feedback from the foot sole modulates the soleus response to proprioceptive stimuli during standing through coherence and cross-correlation analysis. Different cutaneous stimuli at the heel and metatarsals have varying effects on the stretch reflex pathway, with modulation at the a-motoneuron pool being a key mechanism. These findings highlight the functional tuning of the stretch reflex pathway by foot sole cutaneous information in controlling upright posture and balance.

Summary: This study found that muscle spindle afferent feedback is modulated during landing to prevent excessive muscle activation and facilitate appropriate musculotendon and joint stiffness.

Summary: The study investigates the relationship between volitional control and stretch reflex sensitivity during tasks that require coordinated muscle activity. The results show that reflex modulation during movement is better explained by background activity in antagonist muscles rather than activity in the muscle homonymous with the reflex.

Summary: This study quantified the passive muscle-tendon properties of the human triceps surae musculotendinous unit in healthy adults using ultrasound imaging and a three-dimensional motion capture system. The medial gastrocnemius and soleus aspects of the Achilles tendon were found to have similar mechanical properties, but the soleus compartment exhibited significantly higher passive force and tendon stress compared to the medial gastrocnemius. Such unequal passive stress between these tendon compartments may contribute to asymmetrical loading and deformation of the Achilles tendon during motion.

Summary: The study found that the stretch tension of KT had a minor effect on spinal motoneuron excitability in the triceps surae during rest, with greater LG H-max responses observed in the pre-taping condition compared to post-taping condition during paper-off KT.

Summary: This review provides an overview of the recent research on the acute and chronic effects of static stretching on joint behaviors and neuromuscular responses. The findings suggest that static stretching can increase joint range of motion and reduce muscle and tendon properties.

Summary: The present study used transcranial magnetic stimulation (TMS) to explore the time course of corticospinal excitability during 30 seconds of static stretching (SS). The results showed an increased corticospinal excitability in the tibialis anterior (TA) muscle during the static lengthened phase of a muscle stretch.

Summary: Static stretching and proprioceptive neuromuscular facilitation stretching techniques can improve range of motion through modulation of neural mechanisms. However, the effects of these neural pathway changes on range of motion with static stretching are still unclear.

Summary: The vestibulospinal tract (VST) is essential for controlling antigravity muscles on the same side of the body, and the balance between the left and right VST excitability is crucial for human postural control. This study investigated the reliability and laterality of using galvanic vestibular stimulation (GVS) to increase the soleus H-reflex in healthy adults, finding no significant difference in the degree of facilitation between the left and right sides, and a moderate positive correlation with the mediolateral position of the center of pressure during standing postural control.

Summary: The study showed that CSAD-KO mice exhibited higher muscle tension and stronger EMG responses in stretch reflex, mainly due to ultrastructural alterations in muscle histology. Additionally, CSAD-KO mice displayed reduced amplitudes of low-frequency brain waves and increased high low-frequency brain waves, indicating biochemical changes in the GABAergic system due to taurine deficiency.

Summary: The study found that ankle sprains can lead to bilateral inhibition of spinal reflex excitability in the soleus muscle, which may explain bilateral sensorimotor deficits following unilateral injury and provide insights into treatment options.

Summary: The study aimed to compare the acoustic stapedius reflex threshold (ART) in traditional and wideband acoustic immittance tests. The results showed that the ART obtained in the wideband test was lower and more accurate compared to the traditional test. The wideband test allowed for better observation of reflex-related changes across multiple frequency bands.

Summary: This study compared experts and novices in reactive jump performance, finding that experts outperformed novices in power output, jump height, neuromuscular activity, and muscle-tendon interaction. By efficiently loading their elastic recoil system, experts achieved higher reactive power output.
