A Single Session of Mirror-based Tactile and Motor Training Improves Tactile Dysfunction in Children with Unilateral Cerebral Palsy: A Replicated Randomized Controlled Case Series

Introduction. This replicated randomized controlled crossover case series investigated the effect of mirror-based tactile and motor training on tactile registration and perception in children with unilateral cerebral palsy (UCP). Methods. Six children with UCP (6-18 years; median 10 years, five male, three-left hemiplegia, four-manual ability classification system (MACS) I, one MACS II and one MACS III) participated. They attended two 90-minute sessions-one of mirror-based training and one of standard practice, bimanual therapy-in alternated order. Tactile registration (Semmes Weinstein Monofilaments) and perception (double simultaneous or single-point localization) were assessed before and after each session. Change was estimated using reliable change index (RCI). Results. Tactile perception improved in four participants (RCI>1.75), with mirror-based training, but was unchanged with bimanual therapy (RCI<1.0 for all participants). Neither intervention affected tactile registration. Discussion. Mirror-based training demonstrates potential to improve tactile perception in children with UCP.
