dc.description.abstractThe vestibular system plays an important role in postural control and an upright posture at the table. Some children have difficulty in their in-seat posture resulting in increased in-seat movement. This research investigated the effect of the Astronaut Training Protocol on a child’s vestibular processing and postural control, and therefore by extension their in-seat behaviour, as well as whether there would be carry over after the protocol was terminated. A single subject quasi experimental ABA research design was used with five participants who were identified with dysfunction in in-seat posture and in-seat movement. Data was collected over three phases: pre-Astronaut Training (A), post- Astronaut Training (B), and Withdrawal phase (A). The Pre Astronaut Training phase consisted of four sessions of sensory integration based occupational therapy, with the Intervention phase following consisting of eight Astronaut Training sessions during which regular sensory integration occupational therapy remained constant, while the Withdrawal phase comprised of four sessions of regular sensory integration based occupational therapy. Four assessments were used to determine vestibular and postural control change at each phase: Movement ABC one-leg balance, Postrotary Nystagmus (PRN) test, inseat posture assessment (designed for the purpose of this study), and in-seat movement through the collection of data using an accelerometer. Repeated measures of the prone extension and supine flexion positions were used at each therapy session to measure both vestibular processing and postural control. Improvements in postural control and vestibular function were seen in prone extension and supine flexion quality and time for most participants post-Astronaut Training (B). A large effect size indicating a clinical change for in-seat posture and in-seat movement was found post-Astronaut Training (B), indicating improved posture with less fidgeting at the table. Vestibular improvements were seen at Withdrawal phase (A) for balance and PRN with a medium effect size on balance and large effect size for PRN. Participants’ in-seat posture and in-seat movement did not continue to improve and deteriorated slightly in this phase although this differed depending on their responsivity to PRN and diagnosis.en_ZA
