“…A significant smaller ROM was found for HP feet in both ankle and metatarsophalangeal joints, accordingly to previous works [15], [16]. These differences were due basically to the differences in the evolution of the dorsiflexion angles during propulsion (Figure 2).…”

“…They also reported different results regarding range of motion (ROM). While some studies observed a decreased ankle ROM of pronated feet in the sagittal plane [15], [16] and increased in the frontal plane [15], [17], [18], other works found no significant differences in any motion plane [19], [20]. At the midtarsal joint, one study observed a decrease in the ROM for pronated feet in the transverse plane [13], although others found no significant differences in any motion plane [19].…”

“…The study of these dynamic stiffnesses in feet with different static postures may help to understand the well-known relationship between the static foot posture and the development of lower limb injuries [12]. To date, only the effect of the static posture on foot kinematics during gait has been studied [13]- [16], but reporting contradictory data. These works found inconsistent data in peak value dependency, probably because they are affected by the reference posture [12], [14], but also by the approach applied to determine relative motion.…”

This study aimed to analyse the dynamic stiffness of foot joints during gait in the sagittal plane in feet with different static foot postures. Seventy healthy adult male subjects with different static postures, assessed by the Foot Posture Index (FPI) (30 normal, 20 highly pronated and 20 highly supinated), were recruited. Kinematic and kinetic data were recorded using an optical motion capture system and a pressure platform, and dynamic stiffness at the different stages of the stance was calculated from the slopes of the linear regression on the flexion moment-angle curves. The effect of foot type on dynamic stiffness and on ranges of motion and moments was analysed using ANOVAs and post-hoc tests, and linear correlation between dynamic stiffness and FPI was also tested. Highly pronated feet showed a significantly smaller range of motion at the ankle and metatarsophalangeal joints and also a larger range of moments at the metatarsophalangeal joint than highly supinated feet. Dynamic stiffness during propulsion was significantly greater at all foot joints for highly pronated feet, with positive significant correlations, although small, with the squared FPI. Highly supinated feet showed greater dynamic stiffness than normal feet, although to a lesser extent. Highly pronated feet during normal gait experienced greatest decrease in the dorsiflexor moments during propulsion. Normal feet were found to be the most balanced regarding work generated and absorbed.

“…Motor responses to the altered sensory inputs could thereafter affect muscle function and the foot mechanics associated with that foot posture [2,3]. Indeed, muscle strength and function have been shown to be related to foot posture [4] and different foot kinematics exhibited between cavus, planus and normal foot postures [5].…”

“…Being in direct contact with the foot [1], the insole supports body weight. Therefore, it directly affects the biomechanics of the foot and the body as a whole [2]. An anatomical insole should be intended to reduce and adequately distribute plantar pressure among support points, thus minimising the stress these points can undergo during the execution of physical activity or while standing for long periods.…”

Abstract. Anatomical insoles and additions have a corrective action on the footwear user. They are intended to reduce and adequately distribute plantar pressure among support points, thus minimising the stress these points can undergo. Such customised components have traditionally been manufactured by subtractive techniques, i.e. by milling a sheet of material. Latest advances in additive manufacturing (AM) techniques and, in particular, the popularisation of 3D printing by fused deposition modelling (FDM), have opened new ways for the production of anatomical insoles. These technologies allow additional functionalities to be added, as for instance the use of materials with antimicrobial properties, or, at a structural level, zonal control in 3D design to increase cushioning capacity. The latter cannot be achieved by traditional manufacturing techniques, in that the inside of the element is not accessible. However, there are no CAD tools available for the design and production of insoles, which are specifically oriented to take advantage of the benefits that AM can bring about. This paper describes a new methodology intended for the functionalisation of anatomical insoles through a systematic approach. On the one hand, internal structures are automatically obtained by parametric design; on the other hand, the 3D geometry of the insole or addition is adequately processed so that it can be printed by FDM, thus circumventing the constraints of this production technique.
