Background: Guidelines to assist with decision making for orthotic management of gait dysfunction in individual with cerebral palsy (CP) is difficult to derive and remain controversial. The research question is whether supracondylar knee ankle foot orthosis (SKAFO) is one of best options for knee hyperextension and heel rise for spastic diaplegic Cerebral palsy. Aim: The purpose of this study was to check the efficacy of bilateral molded SKAFO for knee hyperextension and heel rise for Cerebral palsy in terms of gait parameters and energy expenditure. Materials and Methods: Five individuals (mean age 3.5 years) were diagnosed as spastic diplegic and one with hemiplegic (age 5 years old) Cerebral palsy with delayed milestone presented with knee hyperextension and heel rise during mid-stance and were fitted with bilateral molded SKAFO with pair of shoes. Observational gait analysis by video recording was performed and gait parameters by 10 m walk test and energy expenditure using physiological cost index was recorded in bracing and non-bracing conditions. Results: The orthosis controlled knee hyperextension by not allowing the knee to go beyond neutral position. The gait was more natural with proper heel strike and better push off. There was improvement in temporal-spatial gait parameters and gait was energy efficient. Conclusion: The SKAFO was found to be effective in controlling knee hyperextension and resulted in stable, natural, satisfactory and energy efficient gait in spastic Cerebral palsy with knee hyperextension and heel rise. Similar study involving case series can be used to set the prognosis of ambulation and the kind of orthotic interventions needed to optimize the walking ability.
