Abstract Background Running on sand could be a promising exercise intervention for the treatment of over-pronated feet. However, there is a lack of knowledge about the effects of running on sand on muscle activities. Therefore, this study aims to evaluate the long-term effects of running on sand on the activities of selected lower limb muscles in individuals with OPF compared with healthy controls. Methods Sixty recreational adult male runners with over-pronated feet (foot posture index > 10) were divided into two equal groups (intervention and control). Participants ran barefoot at a pre-defined speed (⁓3.3 m/s) over level stable ground both before and after long-term training on the sand. Muscle activities were recorded using a surface bipolar electromyography system. Results For the intervention group, we found a reduced foot posture index (p < 0.001; d = 2.00) and significant group-by-time interactions for gluteus medius activity during the mid-stance phase (p < 0.028; d = 0.59). Significantly higher gluteus medius activity (p = 0.028, d = 0.569) was found during the post-test. We also observed significant group-by-time interactions for medial gastrocnemius activity during the push-off phase (p < 0.041; d = 0.54). Significantly larger medial gastrocnemius activity (p = 0.041; d = 0.636) was found during the post-test compared to the pre-test. Conclusions Long-term running on sand resulted in reduced pronation, increased medial gastrocnemius activity, and improved frontal plane pelvic stability due to higher gluteus medius activity.

Background: Physical activity in children may provide health benefits. We sought to consider the practice of soccer as a possible major factor in the development of the lower limb. The study is based on 3-year data for a group of children who practice this sport. Methods: For 3 years we monitored 53 children who practiced soccer 3 times a week and had engaged in 2 years of continuous sports activity. Their mean ± SD age was 8.49 ± 2.01 years in the first year. Each year, Foot Posture Index, valgus index, subtalar joint axis, and Q angle for the knee were analyzed. Results: The mean ± SD Foot Posture Index scores ranged from 5.38 ± 1.79 in the right foot and 4.49 ± 1.67 in the left foot in the first year to 4.64 ± 2.51 and 4.34 ± 2.26, respectively, in the third year. The valgus index for the same period ranged from 14.05° ± 1.51° (right) and 13.88° ± 1.46° (left) to 13.09° ± 1.28° and 13.07° ± 1.07°, respectively. In the knee, the Q angle ranged from 12.83° ± 1.98° (right) and 12.74° ± 1.68° (left) to 13.17° ± 1.45° and 13.26° ± 1.46°, respectively. In the subtalar joint, the changes were 37.73% right and 30.19% left between the first and third years toward a neutral subtalar joint axis. Conclusions: These results show that although playing soccer might cause structural changes in the lower limb, these alterations should not be considered harmful because they may be influenced by age as well.

Background: The angle of turnout is thought to predispose professional dancers to overuse musculoskeletal injuries of the lower limb; yet, the influence of angle of turnout on foot posture is currently unknown. Methods: Twelve professional contemporary dancers (five women and seven men; mean age, 26.8 years) were recruited. The angle of gait and angle of turnout were measured using a quasi-static clinical tracing method. Foot posture was assessed in the base of gait and angle of turnout using the Foot Posture Index. Each dancer completed a dance history and injury questionnaire. Results: The results show a tendency toward a pronated foot posture (mean, 9°) in the angle of turnout position. A significant relationship was noted between the Foot Posture Index and angle of turnout (ρ = 0.933–0.968, P &lt; .01) and between the number of reported injuries and change in foot posture in the angle of turnout (ρ = 0.789, P &lt; .01) (right foot only). Twenty-eight injuries were reported; male dancers experienced a mean of 2.8 injuries and females a mean of 1.6 injuries. An inverse relationship was noted between age at training initiation and total reported injuries (r =−0.867, P &lt; .01). All of the dancers reported a history of injury to the spine or lower limb, and 9 of the 12 reported an injury within the previous 12 months. Conclusions: Turnout is one of the most fundamental aspects of dance technique. This study suggests a trend toward pronation in angle of turnout and a link to lower-limb musculoskeletal injury.

Background: The Foot Posture Index (FPI) is a clinical tool for diagnosis that aims to quantify the grade of a foot position as neutral, pronated, or supinated. Its purpose is to develop a simple six-factor method for rating foot posture with an easy and quantitative result. We evaluated possible differences in the FPI by sex and the influences of age, weight, height, foot size, and body mass index (BMI) on foot posture. Methods: In 150 asymptomatic children (79 boys and 71 girls) aged 8 to 13 years, we determined weight, height, BMI, and FPI in the bipedal, static, and relaxed position. The FPI was obtained as the sum of the scores (–2, –1, 0, 1, 2) given to each of the six criteria. Results: The mean ± SD FPI value for the total sample was 5.1 ± 2.1 (boys: 5.1 ± 2.2; girls: 5.2 ± 2.0), so there were no significant differences between the sexes (P = .636). Of the 150 feet examined, none had FPI values of very supinated or highly pronated, two were supinated (1.3%), 76 neutral (50.7%), and 72 pronated (48.0%). Of the total FPI values, 7.7% can be explained by anthropometric variables: height, weight, and foot size (r2 = 0.077; P &lt; .010). Conclusions: The most frequent foot postures in the sample were neutral and pronated. Neither age nor BMI explained variations in the FPI.

Foot Position

The Foot Posture Index is a new multidimensional and multiplanar tool aimed at quantifying the degree of pronation to supination of the foot, comprising eight criteria that sum to produce a final “score” of foot posture. In an initial study involving 31 subjects, angulations measured from dorsoplantar and lateral radiographs were compared with the corresponding Foot Posture Index criteria using Spearman’s rho and the generalized linear model of analysis of variance. Eleven of the participants from Study 1 completed a second study in which wedges were used to alter foot position to determine whether changes to foot position were sensitively reflected in Foot Posture Index criterion scores and associated radiographic images. Study 1 demonstrated a significant correlation for only one criterion (talar head palpation), while Study 2 demonstrated intrasubject sensitivity to overall changes from supinated to pronated and supinated to resting positions but insensitivity to changes from resting to pronated positions. The results suggest that although the Foot Posture Index could be a useful tool to broadly classify foot postures, it is not sensitive to all small movements when assessed by this method.

The Relationship

Background: The path of the center of pressure during walking varies among individuals by deviating to a greater or lesser extent toward the medial or lateral border of the foot. It is unclear whether this variance is systematic and is affected by foot posture. The aim of this study was to explore the relationship between foot morphology and center-of-pressure excursion during barefoot walking. Methods: Pressure data were collected from 83 participants whose foot type had been classified as supinated, normal, or pronated according to the Foot Posture Index. Three center-of-pressure variables were analyzed: medial excursion area, lateral excursion area, and total excursion area. Results: Across the spectrum of foot types, we found that the more supinated a participant’s foot posture, the larger the area of lateral center-of-pressure excursion, and, conversely, the more pronated the foot posture, the smaller the area of lateral center-of-pressure excursion. Furthermore, the supinated foot type had a relatively larger center-of-pressure total excursion area, and the pronated foot type had a relatively smaller center-of-pressure total excursion area. Conclusions: These results indicate the importance of assessing foot posture when measuring center of pressure and may help explain regional differences in pain and injury location among foot types.
