AbstractThe posterior tibial tendon plays a key role in positioning the foot for effective propulsion during gait. Posterior Tibial Tendon Dysfunction (PTTD) is a common tendinopathy that leads to flatfoot deformity with a profound decrease in gait function. Single leg heel rise (SLHR) is a key functional test for assessing PTTD as its successful completion requires dynamic stabilization of the hindfoot by the PTT. Numerous studies have investigated differences in gait kinematics and kinetics between patients with PTTD and healthy controls, but there is limited data comparing the stability during SLHR between these groups. The purpose of this study was to: (1) summarize the previous findings of gait alterations with PTTD in order to obtain a comprehensive understanding of the differences between PTTD patients and healthy control, and (2) to extend these findings by comparing differences in frontal plane foot kinematics and kinetics during gait and SLHR. The results from this study showed conclusive changes in foot kinematics and kinetics of PTTD patients during both gait and SLHR. These changes may be associated with the pathological process of PTTD and provide a more comprehensive understanding in optimizing treatment and standardization of care of PTTD.
