“…On the other hand, Costa et al ( 2021) determined that the use of insoles with arch support and different medial wedges in the hindfoot reduced the eversion angle of the ankle. This angle decreased during the stroke in the initial support phase and increased in the propulsion phase with wedges of 6 and 9 degrees of inclination during walking and running [17].…”

This study focuses on the assessment of the mechanical effect produced by Morton’s extension as an orthopedic intervention in patients with bilateral foot pronation posture, through a variation in hindfoot and forefoot prone-supinator forces during the stance phase of gait. A quasi-experimental and transversal research was designed comparing three conditions: barefoot (A); wearing footwear with a 3 mm EVA flat insole (B); and wearing a 3 mm EVA flat insole with a 3 mm thick Morton’s extension (C), with respect to the force or time relational to the maximum time of supination or pronation of the subtalar joint (STJ) using a Bertec force plate. Morton’s extension did not show significant differences in the moment during the gait phase in which the maximum pronation force of the STJ is produced, nor in the magnitude of the force, although it decreased. The maximum force of supination increased significantly and was advanced in time. The use of Morton’s extension seems to decrease the maximum force of pronation and increase supination of the subtalar joint. As such, it could be used to improve the biomechanical effects of foot orthoses to control excessive pronation.

“…The height of the wedge used can vary depending on the pronation angle in the foot. Costa et al 31 reported that high supports in runners were effective on lower extremity biomechanics. Considering that the 6-mm standard medial heel wedge used in this study improved balance on the left side while the use of a wedge at a higher subtalar foot angle on the right did not make a difference in balance on the right side, it may be more effective to prefer higher wedges in individuals with a higher pronation angle.…”

Background: Foot orthoses changing the momentum in the subtalar joint are often recommended, especially in activities loading the foot, to bring the pronated foot posture closer to neutral. Objective(s): To examine the immediate effect of medial heel wedge on static balance and load distribution in patients with increased pronation in the foot. Study Design: Experimental study design. Methods: Forty people with right dominant lower extremity participated in the study. For static balance assessment, we assessed ellipse surface, sway length, x-y mean, AP index, and Romberg ratio on 1 foot and measured load distribution as right-left foot and fore-hind foot with and without wedge. Results: There was a difference between the parameters of the ellipse surface and the Romberg ratio on the left side in the measurements performed with and without wedge for static balance on the left side (P < 0.05) while there was no difference in the remaining values (P > 0.05). In the load distribution, the change in the right anteroposterior foot was significant, increasing the load on the forefoot with the wedge (P < 0.05) while we observed no difference in the left fore-hind foot load distribution and right-left foot load distribution (P > 0.05). Conclusion: Our study showed that for static balance, medial wedge can improve balance on the left side by decreasing sway, and for load distribution, the medial wedge changed the load distribution from back to front on the right side. These small differences in young healthy individuals are a preliminary indication that further studies are needed.

“…This wedge was custom made on a CNC (Computer Numerical Control) milling machine also using EVA (shore 40) and were fixed within the shoe using double-sided tape underneath the insoles from the calcaneus to the end of the medial longitudinal arch support. A previous study showed that wedges inclined at 6º could promote significant changes in the kinetics and kinematics of the lower limbs during walking and running [25].…”
