This study aims to investigate and compare the influence of plantar loading variables during gait of patients with diabetic in young ages. Subjects were divided into the following two groups: diabetic foot, 56 subjects; control group, 52 subjects. Plantar pressure distribution was measured during barefoot gait using the Novel emed platform. Both midfoot and lateral forefoot regions’ peak pressure in the diabetic foot was higher than the normal foot. Also, diabetic foot group experienced significantly higher in pressure-time integral and contact time. Those variables provided an indication of plantar loading behavior over time, and other kinesiological factors like joint deformities and mobility can be investigated in further study.

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: Diabetic neuropathy leads to progressive loss of sensation, lower-limb distal muscle atrophy, autonomic impairment, and gait alterations that overload feet. This overload has been associated with plantar ulcers even with consistent daily use of shoes. We sought to investigate and compare the influence of diabetic neuropathy and plantar ulcers in the clinical history of diabetic neuropathic patients on plantar sensitivity, symptoms, and plantar pressure distribution during gait while patients wore their everyday shoes. Methods: Patients were categorized into three groups: a control group (CG; n = 15), diabetic patients with a history of neuropathic ulceration (DUG; n = 8), and diabetic patients without a history of ulceration (DG; n = 10). Plantar pressure variables were measured by Pedar System shoe insoles in five plantar regions during gait while patients wore their own shoes. Results: No statistical difference between neuropathic patients with and without a history of plantar ulcers was found in relation to symptoms, tactile sensitivity, and duration of diabetes. Diabetic patients without ulceration presented the lowest pressure–time integral under the heel (72.1 ± 16.1 kPa × sec; P = .0456). Diabetic patients with a history of ulceration presented a higher pressure–time integral at the midfoot compared to patients in the control group (59.6 ± 23.6 kPa × sec × 45.8 ± 10.4 kPa × sec; P = .099), and at the lateral forefoot compared to diabetic patients without ulceration (70.9 ± 17.7 kPa sec × 113.2 ± 61.1 kPa × sec, P = .0193). Diabetic patients with ulceration also presented the lowest weight load under the hallux (0.06 ± 0.02%, P = .0042). Conclusions: Although presenting a larger midfoot area, diabetic neuropathic patients presented greater pressure–time integrals and relative loads over this region. Diabetic patients with ulceration presented an altered dynamic plantar pressure pattern characterized by overload even when wearing daily shoes. Overload associated with a clinical history of plantar ulcers indicates future appearance of plantar ulcers. (J Am Podiatr Med Assoc 99(4): 285–294, 2009)

Loss of heel pad elasticity has been suggested as one of the possible explanations of heel pain. This study aimed to determine the effect of heel pad thickness and its compressibility to heel pressure distribution, in 47 (94 feet) normal subjects and 59 (94 feet) patients with heel pain, using radiological measurements and EMED-SF (Novel, Munich) plantar pressure distribution measurement system. Both heels of the patients and control group were radiographed with and without weight bearing. The ratio of the heel pad thickness in loading to unloading position was defined as “the heel pad compressibility index.” The plantar peak pressure of the heel was measured at heel strike phase of the gait cycle. The compressibility index for control and patient groups were found to be 0.60 and 0.69, respectively. The peak pressure under the heel pad was recorded to be 28.4 N/cm2 for patients and 31.7 N/cm2 for control group. No significant difference was found for heel pad compressibility index and heel pad pressures between patient and control groups (p>0.05). This study revealed that there is no relationship between heel pad compressibility and pressure distribution of the heel pad both in control and patient group. We feel the flexibility of the heel pad does not have any influence on heel pain syndromes.

The most significant symptoms of autism are abnormal movement patterns that can lead to the decrease of life quality. The purpose of the study was to compare quantitatively the gait strategy of the typical subjects, children with classic high-functioning autism (HFA), and children with low-functioning autism (LFA). Secondly, the comparison and the evaluation of main changes of plantar pressure parameters between groups were presented. The evaluation was carried out on 18 children with HFA, 10 children with LFA, and 30 age-matched children as a control group. A six camera motion capture system, two force plates and a pedobarograph were used to measure gait kinematics, joint kinetics, and pressure distribution under foot during walking. The analysis shows significant differences between children with HFA, LFA, and typical children in velocity, cadence, and magnitude of plantar pressure distribution. The magnitude of plantar pressure was reduced in children with autism under all anatomical masks, which was caused by plano-valgus deformity. Differences were also observed in joint angles and moments during gait cycle. Some of the results can be a source of important information about gait patterns in autistic children. Any exercise treatment prescribed for autistic children should focus on changing the patterns of plantar pressure distribution, which would be similar to patterns of typical children. However, the exercise treatment cannot be generalized due to the high inter-subject variability in children with autism.

Background: The aim of this study was to investigate differences in static and dynamic plantar pressure and other foot geometry variables between female Olympic-style weightlifters and an age- and sex-matched control group. Methods: The study involved 24 national-level competitive weightlifters and 24 physical education students. Leg dominance was determined and baropodometry was used to assess plantar pressure and foot posture during quiet standing and walking. For all variables basic descriptive statistics were calculated (mean ± standard deviation). Student’s t test was used to compare the between-group differences. Spearman’s rank correlation coefficients were calculated to determine the association between BMI (Body Mass Index) and average and peak plantar pressure. Results: No significant differences were observed in plantar pressure distribution between the two groups. A moderate correlation was found between BMI and non-dominant limb peak and average plantar pressure in the group of weightlifters in the static condition and in the control group in the dynamic condition. Conclusions: Olympic-style weightlifting may affect plantar pressure distribution and foot posture in female weightlifters. BMI may also correlate with peak and average plantar pressure in this population. Further research is needed to determine if Olympic-style weightlifting may affect plantar pressure distribution and foot posture in female weightlifters.

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.

This study aims to investigate the kinematics and kinetics of wearing of the different height of shoe toe box walking and jogging. A total of 20 normal males participated in the experiment controlling the jogging speed of 8 km/h and the walking speed of 4 km/h. The Vicon three dimension motions analysis system was taken to capture the kinematics of lower extremity while jogging and walking text. The Novel Pedar-X insole plantar pressure measurement system was utilized to collect the plantar pressure in specific anatomical areas. The function of toe box regions is analyzed through the comparison of plantar pressure parameters and kinematic results. They performed both texts under four conditions which is common sneaker (A), sneaker of Marathon (B), flat sneaker (C) and specially customized sneaker (D). During the walking phase, the ankle of C showed significantly less peak plantar flexion than other shoes. During the jogging phase, the ankle for D showed significantly larger peak flexion than other shoes, and the C is smallest. Meanwhile, the ankle and knee of all shoes expressed different changes in the sagittal and frontal plane. The D of peak pressure and pressure-time integral are obviously higher than other shoes in BT and LFF area. The contact time of D and other shoes exist significant differences in jogging. Compare to wearing different height of shoe box sneakers, the D shoe wearer may enhance BT and forefoot areas power and proprioceptive, to improve athletic performance and to keep balance. The C shoe does not fit sport because it’s having more larger plantar pressure in most of the foot region than other shoes, easy to cause the injury of lower limbs. The A and B shoes are no sensible difference in jogging and walking.
