2.2 Intervention
The Dohsa-hou intervention began in June 2018, and a total of 16 sessions were conducted for 6 months. The content of the Dohsa-hou intervention included interaction tasks, relaxation in the shoulders, back, and trunk, using hip joint in kneeling posture, and standing on the ground.16 The interaction task aimed to improve the interaction between Sara and the therapist by being aware of the therapist’s intention. The therapist joined her hands with Sara, then moved the hand and arm upwards, with Sara matching the movement guided by the therapist.
After the intervention, playtime was set, and interactions with the therapist were video-recorded. Playtime was not set at sessions 1, 3, 6, 8, 12, and 14 due to time constraints. From sessions 2-5, the child played freely, and in sessions 7-16, she and the therapist played with the therapist’s involvement.
Follow-up sessions were conducted 2 months after the end of 16 sessions. The intervention was delivered by a female therapist in training with the supervision of a certified clinical psychologist.
