Effectiveness of Active Exploration of Simulated Textures for Sensorimotor Recovery
Research on the Effectiveness of the Method of Active Examination of Artificially Simulated Textures Generated by Programmable Transcutaneous Electrical Stimulation as a Method of Restoring Sensorimotor Function of the Upper Limbs
About This Trial
Parallel-group, single-blinded controlled clinical trial. The study includes people aged 18-80 years, more than one month after stroke, with confirmed diagnosis, MoCA ≥ 20, and Barthel Index ≥ 3. The control group receives standard rehabilitation. The experimental group also receives active sensory training with programmable electrical stimulation to simulate virtual textures. Sensory function was assessed before and after the training using standard tests, including Fugl-Meyer, ARAT, 9HPT, and monofilament testing.

Active Touch-Based Sensory Training
This intervention combines functional electrical stimulation with active tactile exploration of virtual textures. Using a touch-sensitive screen and a programmable functional electrical stimulator (MotionStim 8), participants explore two invisible virtual textures by moving their index finger across the screen. Each time the finger crosses a virtual texture line, an electrical pulse is delivered to the finger, simulating tactile sensation. Participants are asked to compare the density of two virtual textures and select the denser one. The stimulation is synchronized with finger movement to ensure real-time sensory feedback. The training consists of 50 trials divided into 5 blocks, and is designed to enhance tactile discrimination and proprioception through sensorimotor integration. The paradigm is interactive, personalized based on individual sensory thresholds, and aims to promote neural plasticity in stroke survivors.
