Cutaneous sensory perception training using electrical stimulation: three case studies

It has been demonstrated that sensory ability can be changed by training and that this can cause neuroplastic changes within the brain. This paper describes a device and its use for the training sensory perception by means of electrical stimulation. Additionally the device can be used orthoticly enabling improved ADL skills. The device consists of force sensitive resisters mounted over a pair of self-adhesive electrodes, which place on the pulps of the index finger and thumb. When an object is grasped, the stimulation is delivered, effectively acting as an amplification of normal sensory input. Three CVA subjects are presented whom, after sensory training showed improved proprioception, two point discrimination and Jebsen-Taylor hand function following training
