“…The fundamental concept that foot structure and function may be related has been suggested by a number of investigators [1,15–26]. Song et al examined rectus and planus feet using MVI and CPEI [5] and demonstrated that the planus and rectus foot types resulted in biomechanically distinct foot functions.…”

Background Many foot pathologies are associated with specific foot types. If foot structure and function are related, measurement of either could assist with differential diagnosis of pedal pathologies. Hypothesis Biomechanical measures of foot structure and function are related in asymptomatic healthy individuals. Methods Sixty-one healthy subjects' left feet were stratified into cavus (n = 12), rectus (n = 27) and planus (n = 22) foot types. Foot structure was assessed by malleolar valgus index, arch height index, and arch height flexibility. Anthropometrics (height and weight), age, and walking speed were measured. Foot function was assessed by center of pressure excursion index, peak plantar pressure, maximum force, and gait pattern parameters. Foot structure and anthropometric variables were entered into stepwise linear regression models to identify predictors of function. Results Measures of foot structure and anthropometrics explained 10–37% of the model variance (adjusted R2) for gait pattern parameters. When walking speed was included, the adjusted R2 increased to 45–77% but foot structure was no longer a factor. Foot structure and anthropometrics predicted 7–47% of the model variance for plantar pressure and 16–64% for maximum force parameters. All multivariate models were significant (p < 0.05), supporting acceptance of the hypothesis. Discussion and conclusion Foot structure and function are related in asymptomatic healthy individuals. The structural parameters employed are basic measurements that do not require ionizing radiation and could be used in a clinical setting. Further research is needed to identify additional predictive parameters (plantar soft tissue characteristics, skeletal alignment, and neuromuscular control) and to include individuals with pathology.

“…Using the procedures described in the literature (Faria et al, 2009a, Faria et al, 2010, Hunter and Spriggs, 2000, the triceps surae musculo-articular stiffness was calculated for each of the two trials and the mean was calculated. The musculo-articular stiffness (k) was calculated from the free oscillation data using Eq.…”

“…The oscillations produced at the ankle-foot (plantarflexion/dorsiflexion) were registered and used to assess the musculo-articular stiffness. Participants were prevented from seeing the application of the impulse and were instructed not to react to any stimulus (Faria et al, 2009a, Faria et al, 2010, Hunter and Spriggs, 2000. The impulses were applied randomly to prevent participants from anticipating the impulses.…”

We investigated the mechanical properties of the triceps surae between professional, junior, and nonfootball players. Fifty-nine men participated in this study. The mechanical properties of the right legs' triceps surae were measured in vivo using a free oscillation technique; no significant differences existed between the groups. The mean results for musculo-articular stiffness, damping coefficient, and damping ratio were as follows: professional football players (21523 N.m Thus, football training, football games, and the position played had no effect on triceps surae mechanical properties. These results may be attributed to opposing adaptations between different types of training that are usually implemented in football. Alternatively, the minimum strain amplitude and/or frequency threshold of the triceps surae required to trigger adaptations of mechanical properties might not be achieved by football players with football training and matches.3

“…Of these, six evaluated plantar pressures and three evaluated kinematic relationships, while one study evaluated both of these measures. The mean age of participants was reported in nine studies and ranged from 26.1 ± 0.6 years to 59.2 ± 7.4 years; only two studies provided mean ages for both men and women. There were seven studies that reported mean ages for the different body composition groups.…”

The association between body composition and foot structure and function: a systematic review

et al. 2013

The aim of this systematic review was to investigate the relationship between body composition and foot structure and function. Six electronic databases (Ovid MEDLINE, Ovid EMBASE, Ovid AMED, CINAHL, Scopus and The Cochrane Library) and reference lists from relevant papers were searched on 2 September 2013. Sixteen papers that reported on the association between body composition and foot structure and function met our inclusion criteria and were reviewed. The evidence indicates that obesity is strongly associated with planus (low-arched) foot posture, pronated dynamic foot function and increased plantar pressures when walking. However, there is limited evidence to support an association between other body composition measures, such as fat mass, with foot structure or function.
