Opis:
Twenty-six healthy men and women participated in this study in which 14 were long distance runners and remaining were control subjects. Following the initial assessment of foot pressure distribution, the runners were asked to complete the regular training program. Immediately after the run, foot pressure distribution was again assessed using the Zebris FDM-Treadmill. The parameters were analysed and compared with the pre-training data. The same parameters were also assessed for the control group at rest. Paired t-test was used to compare the foot pressure distribution before and after the run. Independent t-test was used to compare the same parameters between runners and control group. No significant changes were observed in runners post run whereas the control group showed significant changes in the foot pressure distribution of right forefoot and backfoot when compared to long distance runners at rest. The findings of the study suggest that the foot pressure distribution is not affected acutely after the long distance running. The future studies could analyse the plantar pressure measurement throughout the training programs to detect the time and nature of the deviations linked to long distance run, which would help in injury prevention.

Opis:
Ballet is an art that puts extreme demands on the dancer’s musculoskeletal system and therefore significantly affects motor behavior of the dancers. The aim of our research was to compare plantar pressure distribution during stance phase of gait between a group of professional ballet dancers and non-dancers. Thirteen professional dancers (5 men, 8 women; mean age of 24.1 ± 3.8 years) and 13 nondancers (5 men, 8 women; mean age of 26.1 ± 5.3 years) participated in this study. Foot pressure analysis during gait was collected using a 2 m pressure plate. The participants were instructed to walk across the platform at a self-selected pace barefoot. Three gait cycles were necessary for the data analysis. The results revealed higher ( p < 0.05) pressure peaks in medial edge of forefoot during gait for dancers in comparison with nondancers. Furthermore, differences in total foot loading and foot loading duration of rearfoot was higher ( p < 0.05) in dancers as well. We can attribute these differences to long-term and intensive dancing exercises that can change the dancer’s gait stereotype.

Purpose: Osteoarthritis of the knee is one of the most common diseases. For this chronic disease, modified footwear structure can effectively prevent and relieve disease of the knee. The aim of this study was to explore the effects of shoe surface elastic modulus on external knee adduction moment and ground reaction force and foot loading characteristics. Methods: Sixteen healthy female volunteers were recruited, and each subject performed five walking trials under two shoes condition. The lower limb loading data was collected using force platform and in-sole pressure measurement system. Results: The results showed that the external knee adduction moment was decreased in all stance phase when wearing SS (unstable shoes with soft unstable elements), compared with HS (unstable shoes with hard unstable elements). The ground reaction force showed no obvious change under two shoes condition. Additionally, compared with HS, plantar pressure transferred from medial foot to lateral foot when wearing SS. Along with changes of contact areas, average pressure and impulse had also presented this tendency. Conclusions: These results can provide some scientific evidence and suggestions for footwear companies, and for the foot plantar medial injury disease has also certain applicability.

Opis:
Unplanned gait termination (UGT) widely occurs in various sports and daily life as a kind of stress response to unexpected stimulus. However, the body stability may be greatly affected when the body completely stops. The purpose of this study was to examine the association between muscle strength levels and body stability during UGT through comparing the plantar pressure. Methods: Twenty healthy participants (10 male and 10 female) with different lower limbs muscle strength and power were asked to perform planned gait termination (PGT) and unplanned gait termination (UGT) on an 8-m walkway. Related plantar pressure data including maximum pressure, maximum force, contact area and center of pressure were recorded with Footscan pressure platform. Results: Two types of gait termination have significant differences in the plantar pressure distribution. Maximum pressure and maximum force in the lateral metatarsal increased significantly during UGT, compared to PGT. At the same time, data from the current study suggested that there might be a correlation between the muscle strength levels of individual and the stability during the gait termination, especially between the muscle power and UGT, which means that the more excellent muscle power an individual has, the more stable the body is when UGT is performed. Conclusions: The findings suggest that different muscle strength levels could affect stability during unplanned gait termination.

Opis:
Numerous studies on the development of new biofeedback device conception have already been undertaken. Patients with loss of protective pain sensation are unable to modify their gait when abnormal and excessive plantar pressure occurs. For this reason, we have developed and tested a portable baropodometric biofeedback, on healthy subjects, to prevent injuries by informing the subject when local pressure exceeds a determined threshold. Anaesthesia cream enables us to determine the ability to use our device with a perturbation of the plantar sensory inputs. Results showed 58.2% of success steps in the EMLA condition while the placebo condition showed 57.5% of success steps.

Opis:
Numerous studies on new biofeedback devices conception development were undertaken. They are used for some compensation methods of the data lost on sensors set. The aim of the study was carried out for introducing several approaches of investigations and testing of the biofeedback devices that support a plantar pressure analysis, for foot unloading processes implementation. The healthy man is walking in normal conditions first; on a walkway. The recorded load on 6 sensors has to be reduced next in a specified area. The pressure was considered at the beginning on metatarsal head, in time of 100 steps. The visual and auditory signals were then adjusted to a specific plantar pressure threshold setting. The peak pressure was evaluated for various walking condition. The introduced device enables us reducing the peak plantar pressure within the appointed risk-regions.

Opis:
Prolonged running has been popularized globally in recent decades. This study was aimed to reveal information about foot morphology, shoe comfort and plantar loading among recreational heel-strike runners. Methods: Twenty-six runners participated in foot morphology, perceived scores and peak pressure tests after 10- and 20-km track running. The foot morphology was measured using a 3D foot scanner, perceived scores were recorded using a visual analogue scale and plantar pressure was measured via insole plantar pressure measurement system. The statistical significance level was set at 0.05. Results: The heel midsole materials properties were measured before and after 20 km. Significant changes were observed in ball width and girth, arch height and foot volume. The perceived scores showed significance in overall, forefoot and heel comfort, arch support and forefoot width. Peak pressure to the heel, medial mid-foot and metatarsal greatly increased. The first metatarsal showed consecutive increase from static to 10 km, and 20 km, while big-toe showed a decrease. Conclusions: The morphology variations and forefoot loading concentration may lead to discomfort and possibly imply dermatological problems and metatarsal bone stress, particularly on the first metatarsal. Combining changes of heel midsole property, knowledge of foot shape, shoe perception and plantar pressure is of great value for recreational long-distance running shoes design and materials selection.

Opis:
Several factors have been associated with the presence of abnormally high plantar foot pressure including: (i) increased body weight, (ii) foot structure and (iii) walking strategy. It is predicted that the biomechanics of the foot is influenced by the structure of the foot, primarily the Medial Longitudinal Arch. The objective of this study was to examine if Body Mass Index and the foot arch have a direct effect on dynamic peak plantar pressure for healthy subjects. Following a clinical lower limb examination, the Tekscan HR mat was utilised for this study, plantar pressure was profiled at specific events during stance phase of gait including heel strike, midstance and toe off. Results indicated to the preferable normal arch as this produced a low plantar pressure distribution in all cases. The 2nd and 3rd metatarsal head region recorded the highest pressure for all arch types during dynamic analysis. The lowest pressure for the normal and overweight BMI was at toe-off. While the obese BMI group showed highest pressure during toe-off. The obese BMI flat arch subcategory indicated to functional ambulation differences. Future work involves comparing this healthy database to a demographically matched diabetic group.

Opis:
Purpose: Long-distance running has been a global popularity, and differences may be observed in runners of experience. This study was aimed to evaluate the differences in plantar loading between experienced long-distance runners and novice runners during walking. The hypotheses were that smaller load in the middle of the forefoot and the stable foot balance would be observed in experienced runners during walking. Methods: Twenty-five participants were recruited as the experienced runners group (ten: frequency ≥ 4 times/week and distance ≥ 40 km/week, for over 1 year) and the novice group (fifteen: frequency ≤ 2 times/week and distance ≤ 10 km/week, for less than 1 year). Results: The peak Meta loading showed that the novice runners were significantly larger than the experienced runners ( p ≤ .001). The occurring time of peak Meta loading was significantly delayed compared to the experienced runners ( p = .050). Peak Foot balance was higher in the novice runners group ( p ≤ 0.001). Conclusions: This study highlighted the findings of the potential differences of plantar pressures and foot functional parameters during walking in experienced runners and novice runners, specifically the contact duration of phases during stance, toes functions and medial-lateral loading shifting (foot balance) and metatarsals (central forefoot) offloading.

Opis:
Human gait motion analysis was one useful method for lower limb prosthesis study. The most often measured parameters were plantar pressure, kinetic and kinematic parameters. It was indispensable for prosthetic knee design and performance assessment. The aim of this study was to analysis the plantar pressure in traumatic above-knee amputee equipped with a developed microprocessor-controlled prosthetic knee. Methods: The maximum force of forefoot and rearfoot, the average vertical reaction force and pressure and the centre of pressure (COP) offset trajectories of ten above-knee amputees under different walking speeds were obtained. Results: Both forefoot and rearfoot force were bigger in intact leg than prosthetic leg. As the speed increased, the pressure increased in both sides. Forefoot bore more pressure than rearfoot in both legs. The average vertical pressure and force both increased along with the increase of speed. The force and pressure of intact side were always bigger than the prosthetic side. The trend of COP and gait line of the prosthetic and intact side had no significant difference. The length of the gait line of prosthetic side was greater than the intact side. Conclusions: The results of this study exhibited reduced plantar pressure in the prosthetic side. The typical butterfly diagrams were produced during different walking speeds. It indicated that the stability of the microprocessor-controlled prosthetic knee could be guaranteed.

Opis:
The design and development of a plantar pressure control device, adapted to correct plantar pressure distribution patterns, is described. This device is based on the artificial return of information in real time to instantaneously reveal to subject certain events, of which he was unaware and which are difficult to quantify, such as the pressure variation generated by foot-ground contact. An acoustic alarm and visual signals, adjusted to a specific pressure load, alert the user in the case of excessive plantar pressure. So, our feedback device is designed to substitute for loss of feeling in patients who have peripheral neuropathy secondary to diabetes mellitus. The ultimate aim of this project is to prevent the development of neuropathic foot ulceration by providing both visual and auditory extrinsic sensory feedback to compensate for the malfunctioning peripheral nerves and to transmit information to the patient about dangerous conditions on the plantar surface of the feet. A trial of the device in a healthy subject is presented to evaluate whether a new gait pattern can emerge thanks to feedback from plantar pressure measurements.

Opis:
Purpose: It is not known how gait speed affects plantar pressure characteristics in flatfoot. The aim of this work was to investigate the effects of gait speed on plantar pressure variables in flatfoot by comparing it to normal foot posture. Methods: Thirty individuals with flatfoot and 30 individuals with normal foot posture were recruited. Plantar pressure variables were obtained by a pressure-sensitive mat at self-selected slow, normal, and fast speeds. All assessments were performed on the dominant foot, and three satisfactory steps were obtained for each gait speed condition. The order of gait speeds was randomized. Results: In the flatfoot group, the contact area was higher in the midfoot, third metatarsal, and hallux at all speeds, also in the second metatarsal at slow and normal speeds than the normal foot posture group ( p < 0.05). The maximum force was higher in the midfoot and hallux at all speeds in the flatfoot group ( p < 0.05). Also, the maximum force was lower in the first metatarsal at normal and fast speeds, and in the lateral heel at fast speed ( p < 0.05). In the flatfoot group, the peak pressure was found to be higher in the hallux at slow speed, but to be lower in the first metatarsal at fast speed ( p < 0.05). Further, plantar pressure distribution was affected by gait speed in both feet. Conclusions: Analysis of plantar pressure variables should be performed at different gait speeds.
