This study was aimed to analyze the foot posture index and plantar pressure characteristics of fifteen badminton players and fifteen controls. The hypothesis was that people with the habit of playing badminton would be significantly different with nonplaying people in foot posture index, 3D foot surface data, and plantar pressure distribution. Nine regions of plantar pressure were measured by using the EMED force platform, and badminton players showed significantly higher peak pressure in the hallux (p=0.003), medial heel (p=0.016), and lateral heel (p=0.021) and force-time integral in the hallux (p=0.002), medial heel (p=0.026), and lateral heel (p=0.015). There is no asymmetrical plantar pressure distribution between the left foot and the right foot of players. The mean foot posture index values of male and female badminton players are 5.2 ± 1.95 and 5.7 ± 1.15, respectively, and comparatively, those values of male and female controls are 1.5 ± 1.73 and 1.7 ± 4.16, respectively. This study shows that significant differences in morphology between people with the habit of playing badminton and people without that habit could be taken as a factor for a future study in locomotion biomechanics characteristics and foot shape of badminton players and in a footwear design in order to reduce injury risks.

Foot Posture

Background: Fatigue due to running has been shown to contribute to changes in plantar pressure distribution. However, little is known about changes in foot posture after running. We sought to compare the Foot Posture Index before and after moderate exercise and to relate any changes to plantar pressure patterns. Methods: A baropodometric evaluation was made, using the FootScan platform (RSscan International, Olen, Belgium), of 30 men who were regular runners and their foot posture was examined using the Foot Posture Index before and after a 60-min continuous run at a moderate pace (3.3 m/sec). Results: Foot posture showed a tendency toward pronation after the 60-min run, gaining 2 points in the Foot Posture Index. The total support and medial heel contact areas increased, as did pressures under the second metatarsal head and medial heel. Conclusions: Continuous running at a moderate speed (3.3 m/sec) induced changes in heel strike related to enhanced pronation posture, indicative of greater stress on that zone after physical activity. This observation may help us understand the functioning of the foot, prevent injuries, and design effective plantar orthoses in sport. (J Am Podiatr Med Assoc 103(2): 121–125, 2013)

Background: Proximal crescentic osteotomy (PCO) in patients with moderate-to-severe hallux valgus (HV) is a well-established and effective procedure for correcting the deformity. However, there are no published studies comparing plantar pressure in postoperative HV feet with healthy feet. This study aimed to compare the plantar pressure distribution in postoperative HV feet with healthy feet. Methods: Twenty-six patients were included in the HV group, and 24 healthy participants were included in the control (C) group. All patients in the HV group underwent unilateral PCO. After undergoing PCO, this group was defined as the OP group. All subjects were women with no significant differences in age, height, weight, and body mass index. There were no significant differences in demographic characteristics between patients in each group. We divided the subjects’ feet into 8 regions and measured the peak pressure (Peak-P), maximum force (Max-F), contact time, contact area, and the force-time integral in each region. Results: All parameters of the great toe were significantly higher in the OP group than in the HV group. All forefoot parameters were not significantly different between the 2 groups. No parameter of the great toe was significantly different between the OP and C groups. However, mean Peak-P and Max-F of the central forefoot were significantly higher in the OP group than in the C group. Conclusion: PCO can improve the plantar pressure of the great toe in patients with moderate-to-severe HV to a level similar to that in healthy subjects. Level of Evidence: Level III, comparative study.

Abstract Background: Plantar pressure distribution has been recognized as a significant finding to associate with various feet conditions. Objectives: To determine the feet plantar pressure distribution among female school teachers; Methods: This research consisted of 124 female school teachers. Respondents was asked to walk at a regular pace for 10 seconds from a fixed starting point while using footwear pressure insole device and pressure measurement was recorded.; Results: The findings show that lateral heel exerted the most pressure in the right and left foot (94 kPa vs 85 kPa). The second highest average of plantar pressure distribution for right foot among female school teachers was medial forefoot (67 kPa), followed by central forefoot (55 kPa), lateral forefoot (52 kPa) and lateral midfoot with 49 kPa. For the left foot, the second highest for average of plantar pressure distribution was medial forefoot (58 kPa), followed by lateral forefoot (48 kPa), and central forefoot (47 kPa) and lateral midfoot (33 kPa). The result was significant differences as the right foot often exerted greater pressure on any part of the foot than the left foot; Conclusions: The pressure plantar distribution of foot reflects the conditions of school teachers with various posture and movement.

Background Flatfoot, or pes planus, is one of the most common foot posture problems in children that may lead to lower-extremity pain owing to a potential increase in plantar pressure. First, we compared plantar pressure distribution between children with and without flatfoot. Second, we examined the reliability and accuracy of a simple metric for characterization of foot posture: the Clarke angle. Third, we proposed a mathematical model to predict plantar pressure magnitude under the medial arch using body mass and the Clarke angle. Methods Sixty children with flatfoot and 33 aged-matched controls were recruited. Measurements included in-shoe plantar pressure distribution, ground reaction force, Clarke angle, and radiography assessment. The measured Clarke angle was compared with radiographic measurements, and its test-retest reliability was determined. A mathematical model was fitted to predict plantar pressure distribution under the medial arch using easy-to-measure variables (body mass and the Clarke angle). Results A high correlation was observed between the Clarke angle and radiography measurements (r &gt; 0.9; P &lt; 10−6). Excellent between- and within-day test-retest reliability for Clarke angle measurement (intraclass correlation coefficient, &gt;0.9) was observed. Results also suggest that pressure magnitude under the medial arch can be estimated using the Clarke angle and body mass (R2 = 0.95; error, &lt;0.04 N/cm2 [2%]). Conclusions This study suggests that the Clarke angle is a practical, reliable, and sensitive metric for quantification of medial arch height in children and could be recommended for research and clinical applications. It can also be used to estimate plantar pressure under the medial arch, which, in turn, may assist in the timely intervention and prognosis of prospective problems associated with flatfoot posture.

Context: Running is a popular sport globally. Previous studies have used a gait retraining program to successfully lower impact loading, which has been associated with lower injury rates in recreational runners. However, there is an absence of studies on the effect of this training program on the plantar pressure distribution pattern during running. Objective: To investigate the short-term effect of a gait retraining strategy that uses visual biofeedback on the plantar pressure distribution pattern and foot posture in recreational runners. Design: Randomized controlled trial. Setting: Biomechanics laboratory. Participants: Twenty-four recreational runners were evaluated (n = 12 gait retraining group and n = 12 control group). Intervention: Those in the gait retraining group underwent a 2-week program (4 sessions/wk, 30 min/session, and 8 sessions). The participants in the control group were also invited to the laboratory (8 times in 2 wk), but no feedback on their running biomechanics was provided. Main Outcome Measures: The primary outcome measures were plantar pressure distribution and plantar arch index using a pressure platform. The secondary outcome measure was the foot posture index. Results: The gait retraining program with visual biofeedback was effective in reducing medial and lateral rearfoot plantar pressure after intervention and when compared with the control group. In the static condition, the pressure peak and maximum force on the forefoot and midfoot were reduced, and arch index was increased after intervention. After static training intervention, the foot posture index showed a decrease in the foot pronation. Conclusions: A 2-week gait retraining program with visual biofeedback was effective in lowering rearfoot plantar pressure, favoring better support of the arch index in recreational runners. In addition, static training was effective in reducing foot pronation. Most importantly, these observations will help healthcare professionals understand the importance of a gait retraining program with visual biofeedback to improve plantar loading and pronation during rehabilitation.

BACKGROUND: Flexible flatfoot is associated with altered plantar pressure distribution, but it is not clear how muscle fatigue affects plantar pressure characteristics in flexible flatfoot and normal foot. OBJECTIVE: To investigate the effects of calf muscles fatigue on plantar pressure variables in flexible flatfoot and normal foot. METHODS: Twenty-five people with flexible flatfoot and twenty-five people with normal foot were included. The unilateral heel-rise test was used to induce calf muscles fatigue. Plantar pressure variables were collected during preferred walking immediately before and after fatigue. The two-way mixed-design ANOVA was used to determine the main effect of fatigue and the interaction between foot posture and fatigue. RESULTS: Fatigue causes medialization of the contact area under the forefoot and the maximum force under the heel and forefoot (p< 0.05). When examining the differences in the effects of fatigue between groups, the contact area under the medial heel increased with fatigue in flexible flatfoot but decreased in normal foot; moreover, the contact area and maximum force under the midfoot and the maximum force under the third metatarsal decreased with fatigue in flexible flatfoot but increased in normal foot (p< 0.05). CONCLUSIONS: Calf muscles fatigue causes medialization of the maximum force and contact area. Especially the midfoot was affected differently by fatigue in flexible flatfoot and normal foot.

Background.Changes in biomechanical structures of human foot are common in the older person, which may lead to alteration of foot type and plantar pressure distribution. We aimed to examine how foot type affects the plantar pressure distribution and to determine the relationship between plantar pressure distribution and functional reach distance in older persons.Methods.Fifty community-dwelling older persons (age:69.98±5.84) were categorized into three groups based on the Foot Posture Index. The plantar pressure (max⁡P) and contact area were analyzed using Footscan® RSScan platform. The Kruskal-Wallis test was used to compare the plantar pressure between foot types and Spearman’s correlation coefficient was used to correlate plantar pressure with the functional reach distance.Results.There were significant differences ofmax⁡Pin the forefoot area across all foot types. The post hoc analysis found significantly lowermax⁡Pin the pronated foot compared to the supinated foot. A high linear rank correlation was found between functional reach distance andmax⁡Pof the rearfoot region of the supinated foot.Conclusions.These findings suggested that types of the foot affect the plantar maximal pressure in older persons with functional reach distance showing some associations.
