In this feasibility study, we present a novel, wearable prototype of tactile biofeedback to alleviate gait disturbances, such as freezing of gait in Parkinson's disease. We designed and tested a phase-dependent tactile biofeedback system that can be easily worn on the feet, with a simple switch to turn it on or off. Preliminary validation was performed in 8 subjects with Parkinson's disease who show freezing during a turning in place test. A metronome, control condition was used to compare effectiveness in alleviating freezing. Promising results were obtained, both in term of acceptability of the device, and improving motor performance.

Smart wearable tactile systems, designed to deliver different types of touch feedback on human skin, can significantly improve engagement through diverse actuation patterns in virtual or augmented reality environments. Here, a perpendicularly nested auxetic wearable haptic interface is reported for orthotropically decoupled multimodal actuation (WHOA), capable of producing diverse tactile feedback modes with 3D sensory perception. WHOA incorporates shape memory alloy wires that are intricately knotted into an auxetic structure oriented along orthotropic dual axes.

Article Synopsis
- - Somatosensory neuroprostheses are devices designed to restore or enhance touch and body awareness in individuals with sensory impairments from neurological issues or injuries, using electrical stimulation methods.
- - Recent advancements have shifted focus from just developing these technologies to actual clinical studies, showing promising results in how they affect sensory perception, function, and mental well-being.
- - The review discusses ongoing human trials, findings on the effectiveness of these systems, potential improvements for more realistic sensory experiences, and outlines challenges that still need to be overcome for wider use.
Visuomotor prediction during action planning in the human frontoparietal cortex and cerebellum.

Article Synopsis
- The study explores how the brain uses forward models for action planning, extending the traditional use in motor control to include predictions during movement preparation.
- Using a virtual reality setup and fMRI, participants prepared hand movements with varying cues about movement type and visuomotor mapping, revealing distinct brain activity patterns.
- Findings indicate that motor planning involves anticipating visual feedback related to body movements, suggesting that adjustments are made in the cerebellum and integrated in the anterior intraparietal sulcus when facing unexpected sensory conditions.
