“…Interestingly, generating high pressures under the heel was also associated with lower total physical activity and MVPA in boys. An unexpected finding was that girls in the present study generated their highest pressures under the hallux and not the heel (see Figure 2); however, girls have been shown to generate higher pressure under the hallux compared to boys in a previous study [21]. Although high plantar pressures under the hallux were not significantly correlated with physical activity, they had the strongest association with MVPA in girls.…”

“…Independent t-tests were used to determine any differences in the plantar pressure and physical activity variables between boys and girls. In order to establish the strength of the relationships among peak pressure and the physical activity variables, Pearson product moment correlations were calculated for boys and girls separately as foot structure and dynamic pressure patterns have been shown to differ between boys and girls [18][19][20][21]. A relationship was deemed significant at p ≤ 0.05.…”

It has been speculated that high plantar pressures might cause foot pain and discomfort which, in turn, may discourage children from being physically active and result in them spending more time in sedentary activities. The purpose of this study was to determine whether plantar pressure distributions generated by preschool children were correlated with objectively measured time spent in physical activity and sedentary behaviour. Dynamic plantar pressures were measured for 33 preschool children (age = 4.3±0.6 years; height = 1.06±0.1 m; mass = 18.4±2.9 kg; 17 boys) as they walked across an emed AT-4 pressure platform. Physical activity was objectively assessed using MT ActiGraph accelerometers. Total physical activity (counts per minute), percentage of time spent in moderate-to-vigorous physical activity (MVPA), light activity and sedentary behaviour were then calculated. Peak pressures across the heel were found to significantly correlate with total physical activity (r =−0.53; p = 0.03) and time in MVPA (r =−0.47; p = 0.05) in boys. Similarly, the correlation data suggested that girls who generated higher peak pressures in the toe region spent more time in sedentary behaviour (r = 0.53; p = 0.04). As high plantar pressures appear to be a potential negative correlate of physical activity and sedentary behaviour, it is recommended that further research be conducted to design, test and evaluate the potential of interventions to reduce plantar pressures in inactive children so they can enjoy the benefits associated with participating in a more active lifestyle.

“…Mechanically, this medial collapse of the midfoot combined with greater force production may result in alteration of functional biomechanics of the metatarsals during the pronation phase of gait, further promoting dissipation of energy at the forefoot. 24 Ferrari and Watkinson 24 found that this was more pronounced in girls than in boys. Medial collapse of the midfoot can alter the biomechanics of the foot during normal gait.…”

“…They found that, because of this medial trajectory, the first metatarsal head was loaded more in girls than in boys. 24 Clinically, this may help explain why females are more susceptible than males to hallux valgus disorders. 24 This medial collapse of the midfoot region and resultant pes planus with increased loading at the first metatarsal head also may alter the mechanical advantage of the peroneus longus muscle, leading to decreased eversion and plantar flexion.…”

Context:The relationship between generalized joint laxity and plantar pressure distribution of the foot and the potential implications for lower extremity injury have not been studied.Objective: To determine the relationship between generalized joint laxity and dynamic plantar pressure distribution. We hypothesized that individuals with greater generalized joint laxity, or hypermobility, would have greater dynamic medial midfoot pressure and loading during walking than nonhypermobile individuals.Design: Case control. Setting: Institutional biomechanics laboratory.Patients or Other Participants: Participants included 112 female soccer players between 11 and 21 years of age.Main Outcome Measure(s): Each participant was tested for generalized joint laxity using the Beighton and Horan Joint Mobility Index (BHJMI; range, 0-9) and was categorized as having either high (BHJMI score $4) or low (BHJMI score ,4) generalized joint laxity. Peak pressure and maximum force were calculated from a dynamic, barefoot plantar pressure distribution system.Results: Peak pressure and maximum force were greater in the 27 participants categorized as having high generalized joint laxity than in the 85 participants categorized as having low generalized joint laxity. The midfoot region exhibited greater loading in participants with high generalized joint laxity than in the other participants. We found an effect of BHJMI classification in the medial midfoot; peak pressure in the dominant (F 1,109 5 11.262, P 5 .001) and nondominant (F 1,109 5 14.32, P , .001) sides and maximum force in the dominant (F 1,109 5 7.88, P 5 .006) and nondominant (F 1,109 5 9.18, P 5 .003) sides were greater in the high generalized joint laxity group than in the low generalized joint laxity group.Conclusions: Athletes classified as having high generalized joint laxity demonstrated increased midfoot loading. Delineation of risk factors for medial collapse of the foot, which include hypermobility in athletes, may help clinicians evaluate and prevent lower extremity injury with treatments, such as orthoses.
