Tactile Devices in Post-Stroke Dyscalculia

• Abacus — An ancient manual computing device consisting of a frame with rods along which beads slide. In modern medicine, neuropsychology, and occupational therapy, the abacus is utilized as a tactile therapeutic tool for the cognitive rehabilitation of stroke survivors, traumatic brain injury patients, or early-stage dementia patients, aiding in the recovery of fine motor skills and mathematical executive functions.
