Objectives: This study aimed to demonstrate the efficacy of ortho-prosthesis and knee-ankle foot orthosis (KAFO) in improving functional gait activities in children with congenital limb deficiencies.

Study design: A case report.

Setting: Sirindhorn School of Prosthetics and Orthotics, Faculty of Medicine Siriraj Hospital, Mahidol University.

Subjects: The study presents the case of a 10-year-old child with a left congenital femoral deficiency with fibular hemimelia and right tibial hemimelia.

Methods: A pediatric orthopedist provided surgical treatment, and a prosthetist and orthotist prescribed the design, choosing the appropriate KAFO for the right side and ortho-prosthesis for the left side. Outcome measurements were recorded using the Four Square Step Test (FSST), Time Up and Go (TUG) Test, and the  10-Meter Walk Test after using the devices for two and five months.

Results: The results of FSST and TUG showed improvement after five months of training, with 19.69% and 34.25% less time required, respectively. The parameters of the 10-Meter Walk Test also improved after five months of training.

Conclusions: Appropriate fitting of different devices and training using those devices can help improve balance and functional gait activities in children with congenital limb deficiencies.
