 Bodily sensations include focal or generalized body sensations (usually tactile, muscular-skeletal/visceral, or both); mental sensations include urge only, energy release (mental energy that builds up and needs to be discharged), incompleteness, and just-right perceptions.They may be an important measure for grouping patients along the OCD-Tourette's disorder spectrum.The presence of sensory phenomena differentiates subjects with Tourette syndrome plus obsessive-compulsive disorder (OCD) from subjects with OCD alone.
