The exercise is an activity planned by the therapist as a proprioceptive and motor problem-solving task that the patient has to resolve by utilizing higher cortical functions. The patient needs to select the most significant proprio- ceptive information from the interaction with spe- cific instruments and use the cortical feedback to guide muscle contraction and organize the motor behavior. NCTE is a cognitive sensory motor train- ing rehabilitation focused on sensory retraining, which is important for the execution of fine motor skills.
