The latest researches have adopted software technology by applying the Nintendo Wii Remote Controller to the correction of hyperactive limb behavior. This study extended Wii Remote Controller functionality for improper head position (posture) correction (i.e. actively adjusting abnormal head posture) to assess whether two people with multiple disabilities would be able to actively keep the upright head position by controlling their favorite stimulation using a Wii Remote Controller with a newly developed active head position correcting program (AHPCP). The study was performed according to an ABAB design, in which A represented the baseline and B represented intervention phases. Results showed that both participants significantly increased their time duration of maintaining upright head position (TDMUHP) to obtain the desired environmental stimulation during the intervention phases. Practical and developmental implications of the findings were discussed.
