The control of muscle relaxation is not simply the cessation of a muscle contraction, but a dynamic control mechanism for the next movement. Muscle relaxation is triggered by neurophysiological control of the central nervous system. Here, two relaxation strategies were compared, Ballistic and Ramp conditions, and the dynamics of excitability changes between the two relaxation strategies were analyzed.

Background: Knee osteoarthritis (KOA) is a prevalent condition among older adults, leading to impaired proprioception and reduced gait speed, which compromise mobility and quality of life. While aquatic therapy and transcranial direct current stimulation (tDCS) have individually shown potential for enhancing motor and sensory functions, their combined effects are not well understood.
Objective: This study aimed to evaluate the combined effects of aquatic therapy and tDCS on knee proprioception and gait speed in older women with KOA.

Objective: In temporal interference (TI) transcranial electrical stimulation (tES), an emerging brain stimulation technique, the interference of two high-frequency currents with a small frequency difference is used to target specific brain regions with better focality than in standard tES. While the magnitude of the modulation depth has been previously investigated, an explicit formula for the direction in which this modulation is maximized has been lacking. This work provides a novel closed-form analytical expression for the orientation of maximum modulation depth in TI tES.

Objective: Imposing accurate outflow boundary conditions remains a significant challenge in 3D computational fluid dynamics simulations of patient-specific cerebral blood flow. Widely used Windkessel models often rely solely on geometric factors, such as outlet numbers and diameters, leading to inaccuracies caused by image quality limitations and simplified vessel representations. This preliminary study proposes a novel functional region-based approach to enhance the accuracy of cerebral blood flow simulations.

The therapeutic effects of transcranial magnetic stimulation (TMS) are closely related to the structure of the stimulation coil. Based on this, this study designed an A-word coil and proposed a multi-strategy fusion multi-objective slime mould algorithm (MSSMA) aimed at optimizing the stimulation depth, focality, and intensity of the coil. MSSMA significantly improved the convergence and distribution of the algorithm by integrating a dual-elite guiding mechanism, a hyperbolic tangent control strategy, and a hybrid polynomial mutation strategy.
