Many infants with spina bifida who are moderately to severely neurologically involved have difficulty in achieving hands-free sitting balance. Without trunk support or hand use, such children often collapse forward with their ribs resting on their thighs.

The bucket seat, a custom fitted orthosis, has enabled the child with spina bifida to sit comfortably with hands free to play, eat, and explore the environment.

Criteria for prescription, functional application, and adaptability of the orthosis were presented, together with the casting procedure, fabrication techniques, materials used, fitting, and finishing of the orthosis.
