This time, Yoshiyuki Hirakawa, a graduate of the doctoral course at Kio University Graduate School, and Professor Shu Morioka, director of the Neurorehabilitation Research Center at Kio University, have devised a new treatment method using "shadow painting" for patients who are afraid of such pain. And announced that it was effective.

　The CRPS patient in this case is afraid to load the foot on the ground due to pain, and predictively feels strong pain in the foot just by recalling the load (putting weight on the foot). It hurts just to think about it).As a result, a sense of physical possession and lack of body image were recognized.

　Therefore, when rehabilitation was performed to create the illusion of touching only on the shadow puppets without directly touching the patient's feet, the feeling of physical possession and body image were reshaped, and allodynia (feeling strong pain even with a slight stimulus). The state of being put away) has been reduced.

　Furthermore, by projecting a shadow picture of the foot of a third party on the sheets so that it overlaps the patient's foot and showing the patient how the therapist touches the shadow picture, the illusion of being touched by the patient's foot is achieved. When the rehabilitation was performed, the arodinia of the foot was further reduced, and the walking ability was gradually improved along with the improvement of the physical image.

　In this way, the intervention using shadow puppets has made it possible to improve physical cognitive ability and to form an image of load without anticipating pain.Shadow play intervention is expected to be an effective rehabilitation for patients with foot CRPS who have difficulty in loading to eliminate predictive pain due to loading and improve walking ability.
