Abstract

[Purpose] This study aimed to identify a simple and useful muscle parameter for use with the Gait Deviation Index in assessment of ambulatory children with unilateral and bilateral spastic cerebral palsy. [Participants and Methods] Twenty-eight patients (aged 6 to 18 years; 16 females and 12 males) participated in this cross-sectional study. Outcome measurements included the Gait Deviation Index, grip strength, 5-repetition chair stand test, upper limb skeletal muscle mass index, and lower limb skeletal muscle mass index. [Results] By multiple regression analysis, significant independent correlations were observed between the Gait Deviation Index and 5-repetition chair stand test and the Gait Deviation Index and lower limb skeletal muscle mass index, but not between the Gait Deviation Index and grip strength or upper limb skeletal muscle mass index. [Conclusion] The Gait Deviation Index was correlated with lower limb muscle mass in children with spastic cerebral palsy. Determination of lower limb muscle mass may be useful gait evaluation.
