This area of research focuses on understanding the mechanical effects of flatfoot deformity, primarily related to Posterior Tibial Tendon Dysfunction (PTTD). The goal is to translate work from the lab into clinical practice. Current Studies Include:
Effect of Posterior Tibial Tendon Dysfunction Specific Braces on Foot Kinematics in subjects with stage II Posterior Tibial Tendon Dysfunction (PTTD)
The purpose of this research project is to investigate mechanisms used by common orthotic devices and their short-term clinical effectiveness. The goal is to provide insight for future device design as well as the optimal design for patients today. Various device designs and components are being evaluated with a range of subjects with PTTD.
Quantifying the Effects of Tendon Morphology on Function in subjects with stage II Posterior Tibial Tendon Dysfunction
The purpose of this study is to investigate how foot function may be associated with tendon structure. Various clinical and outcome based measures of foot function will be used in conjunction with high-frequency ultrasound imaging to quantify function and tendon morphology in subjects with stage II PTTD.
This area of research is a collaborative work with the department of Physical Medicine and Rehabilitation.
Effects of correction of leg length inequality on gait in children with cerebral palsy
This is a pilot study aimed at understanding the influence of leg length inequality (LLI) on gait in subjects with cerebral palsy (CP). Leg length inequality (LLI) of more than 1 centimeter (cm) is common in children with cerebral palsy but therapeutic interventions to manage this problem are controversial and unstudied. Although surgical procedures are used to correct gross LLI, correction of more mild (<2.5cm) differences with conservative options have not been explored.
