Summary: Skin sensation limits the intensity of transcranial electrical stimulation (tES), and exploring alternative stimulation waveforms may reduce skin sensation levels. High frequency monophasic square wave stimulation decreases sensation with increasing duty cycle, baseline, and frequency, but never lower than constant current stimulation. Conventional DC and AC waveforms may provide the lowest skin sensation levels for transcutaneous electrical stimulation.

Summary: The study aimed to validate a predictive model for standing posture, joint torques, and support forces for smartphone users, and propose risk scales based on simulations for musculoskeletal disorders prevention. The model was able to accurately estimate posture and reaction forces, providing estimates for a wide range of environmental conditions based on user body mass index. Joint torques risk scales, especially for shoulder and elbow, were constructed to characterize the risks incurred by users.

Summary: This paper presents a novel experimental case study in which tactile sensation is analyzed as 4-dimensional subjective data using a temporal measurement approach. The analysis examples demonstrate the potential use cases of time-series subjective tactile data. The results suggest that temporal measurements may capture more stimulus characteristics and reveal different trends in cluster analysis.

Summary: Moderate coolness is sensed by TRPM8 ion channels in peripheral sensory nerves, but the mechanism by which noxious cold is detected remains elusive. In this study, two distinct mechanisms to detect noxious cold were discovered in somatosensory and sympathetic neurons. The first mechanism involves inhibition of a background outward current by cold, leading to membrane depolarization and activation of an inward current through voltage-dependent calcium channels. The second mechanism is independent of membrane voltage and involves the activation of ORAI ion channels by aggregation of STIM1, which is directly activated by cold and not by calcium store depletion.

Summary: Sensory corpuscles of human skin are terminals of primary mechanoreceptive neurons associated with non-neuronal cells that function as low-threshold mechanoreceptors. Understanding the structure and immunohistochemical profile of these formations is essential in diagnosing and treating various skin pathologies. Cutaneous biopsy may be a useful method for analyzing nerve involvement in peripheral neuropathies and systemic diseases.

Summary: This study aimed to explore the nature of light touch sensation and two-point discrimination (2-PD) of different hand sites in convalescent stroke patients based on somatosensory evoked potentials (SEP). The results showed that light touch sensation was mainly associated with sensory impairment in the finger and palm region. Two-point discrimination in the finger region was mainly sensory loss, while in the palm region it was mainly sensory impairment. Any site on the hand could be selected as the measurement site for light touch sensation, but the little finger and hypothenar may be appropriate sites when screening for 2-PD.

Summary: This article proposes an impedance sensing method using conductivity changes during muscle contraction to estimate muscle-driven joint torques through a convolutional neural network (CNN). The effects of different image formats on CNN performance are experimentally studied on human forearms. The findings show that the impedance-based method can accurately estimate joint torques and data sharing among similar groups can reduce training time for CNN on new subjects.

Summary: This study evaluated the relative latency of intensity-matched vibration and ICMS perception. The results showed that the perception of ICMS lagged behind mechanical stimulation, but the latency differences were small, especially when the stimulus intensities were matched. This suggests that ICMS-based somatosensory feedback is rapid enough to be effective in neuroprosthetic applications.

Summary: This study investigated the effect of non-invasive transcutaneous spinal stimulation on postural stability during upright standing in individuals with multiple sclerosis. Results showed that stimulation significantly improved postural stability during standing with eyes closed, presumably by catalyzing proprioceptive function, whereas no differences were found in standing with eyes open. Future work should confirm underlying mechanisms and explore the clinical value of transcutaneous spinal stimulation for individuals with multiple sclerosis.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
