no === Leg length discrepancy (LLD) refers to the medical a condition where legs are of different lengths. This condition might affect gait and posture, and may lead to various orthopedic disorders that can have serious repercussions on the individual, be it physiological, psychological, social, economic, or ergonomic. In order to ameliorate the rehabilitation of individuals with LLD, it is imperative to understand the biomechanics of LLD in these individuals. Hence, the current study’s objective is to characterize the plantar pressures of individuals with Leg Length Discrepancy in comparison to those of asymptomatic individuals. This pilot study employs a pedar-x in-shoe pedobarograph system to gather the history of dynamic plantar pressures in one adult male individual with LLD and a representative adult normal volunteer with no diagnosed neurological or musculoskeletal disorders. The obtained results reveal quantifiable differences in the study metrics between the two individuals during walking. These results provide a proof-of-concept for this study, and may serve as diagnostic tools to better rehabilitate individuals with LLD and, thus, provide them with a better quality of life. Future work is to incorporate an extended study of 10 normal individuals versus 10 individuals with LLD, and includes both males and females, as well as both adults and adolescents.
