Purpose: The aim of this study was to investigate to immediate effect of using insoles on the healthy extremities of individuals using transtibial prosthesis on plantar pressure and postural stability. Methods: The study was performed on 16 unilateral transtibial amputees aged 18-65 years using transtibial prosthesis. Foot posture, Foot Posture Index, and calcaneus angle were evaluated with the CJ Ortho mobile application (Collège des Jeunes Orthopédistes–CJO) and universal goniometric measurement, foot plantar pressure and postural stability Sensor Medica®️ system. The evaluations made before and after the insoles were recorded instantly. Normal distribution was done with the Shapiro Wilk test and it was determined that all data did not show normal distribution. Wilcoxon Signed Ranks Test, one of the non-parametric tests, was used to reveal the difference between the two dependent variables. The statistical analysis of the study was performed using SPSS 21.00 at the significance limit of 0.05. Results: It was observed that the plantar pressure forces (forefoot loading, total loading, forefoot contact surface, total contact surface) on the intact extremity of the individuals increased and the maximum pressure decreased (p <0.05). It was determined that the subtalar joint angle of the ankle decreased with the insoles, and there was a decrease in the length of postural sway and medio-lateral sway (p <0.05). Conclusion: It was found that the application of personalized insoles on the healthy extremity of amputees using transtibial prosthesis instantly reduces postural sway and improves the plantar pressure distribution of the foot. We think that the use of personalized insoles on the healthy side should be encouraged for amputees using prosthetics.
