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:
The purpose of this study was to determine differences in force steadiness during submaximal plantar flexion (PF) and dorsiflexion (DF) of the dominant leg between individuals experienced and not experienced in resistance training. Forty males aged 18-32 were divided in two groups based on their experience in resistance training (experienced – not experienced). Evaluation of maximal voluntary isometric force was carried out on a Humac-Norm isokinetic dynamometer. The measurement of the maximal voluntary contraction (MVC) was measured in 3 isometric attempts. Then, the stability measurement of 10%, 30%, 50% and 70% of the MVC was assessed. The duration of the isometric contraction was 10 seconds but only 6 seconds were analyzed. T-test for independent samples and ANOVA was applied for the statistical analysis. The results showed that the individuals with more experience in resistance training presented a significantly higher MVC and force steadiness of the plantar and dorsiflexors muscles, compared with the individuals with less experience (p < 0.05). In conclusion, the years of practice with resistance training appear to have a beneficial effect on force steadiness.

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.

Opis:
The objective of this study was to compare the ground reaction forces (GRFs) and the multi-segment foot motion between individuals with plantar fasciitis (PF) and healthy controls. Methods: Twenty-one individuals with PF and 21 matched-case healthy controls who passed the criteria participated in the study. Gait data were assessed during their self-selected comfortable speeds by the 3D motion analysis system. The multi-segment foot motions were determined by the Oxford Foot Model. Outcome measures included the vertical and antero-posterior ground reaction forces (GRFs) and the multi-segment foot motions [the dorsiflexion (DF), plantarflexion (PF), inversion (Inv), eversion (Eve), adduction (Add), and abduction (Abd) peak angles for the forefoot with respect to hindfoot (FFHF) and the DF, PF, Inv, Eve, internal rotation (IR), and external rotation (ER) peak angles for the hindfoot with respect to tibia (HFTB) as well as their ranges (R)]. Results: Comparisons between individuals with PF and healthy controls showed no significant differences in any of the GRFs. Significant reductions were found in the FFHF-DF, FFHF-DF-R, FFHF-Inv, and HFTB-Inv/Eve-R in individuals with PF. In addition, there were tendencies of the increased angles of the FFHF-PF, HFTB-DF, HFTB-Inv, and HFTB-ER, but not significantly for individuals with PF, compared to healthy controls. Conclusions: Adaptations of the intra-foot motion showed the reduction of some angles but no change for the GRFs in individuals with PF compared to the healthy controls when both groups walked at a similar gait speed.

Opis:
Plantar fasciitis is reported as the most common cause of chronic plantar heel pain. An extra-corporeal shock waves have been used in the treatment of plantar fasciitis with promising results. The purpose of this paper was to present results from randomized controlled trials to estimate of the effectiveness of ESWT in the treatment of plantar fasciitis. Method: MEDLINE, EBCO, PubMed, ScienceDirect and SpringerLink databases were searched, using the keywords: ESWT, plantar fasciitis, shock wave, randomized clinical trials. Results: Ten randomized clinical trials was critically appraised. Eight studies report significant decreases in pain symptoms and better function scores associated with an extra-corporeal shock wave therapy. However two studies show no meaningful improvement of clinical outcome in patients treated with extracorporeal shock wave therapy for chronic plantar fasciitis compared with placebo. Summary: In most cases shockwaves therapy was a safe and effective method for treatment of chronic plantar fasciitis and helped the patient to avoid surgery for recalcitrant heel pain but warrants further larger studies.
Zapalenie powięzi podeszwy jest najczęstszą przyczyną przewlekłego bólu podeszwowej strony pięty. Wyniki terapii zapalenia powięzi podeszwy zewnętrzną falą uderzeniową są obiecujące. Celem pracy jest przedstawienie wyników randomizowanych badań klinicznych mających na celu ocenę skuteczności fali uderzeniowej w terapii zapalenia powięzi podeszwy. Metody: Analizą objęto doniesienia opublikowane w bazach: MEDLINE, EBCO, PubMed, ScienceDirect oraz SpringerLink. Użyte słowa kluczowe: terapia zewnętrzną falą uderzeniową, zapalenie powięzi podeszwy, randomizowane badania kliniczne. Wyniki: Wyniki dziesięciu randomizowanych badań klinicznych zostały objęte analizą. Analiza wyników ośmiu z nich wskazuje na istotne zmniejszenie dolegliwości bólowych oraz polepszenie funkcji u pacjentów leczonych przy użyesticiu fali uderzeniowej. Natomiast wyniki pozostałych dwóch badań nie wskazują na znaczącą poprawę stanu pacjentów leczonych falą uderzeniową w porównaniu z grupą kontrolną pacjentów nieotrzymującą leczenia. Podsumowanie: W większości przypadków terapia zewnętrzną falą uderzeniową jest efektywną metodą leczenia zapalenia powięzi podeszwy, pomaga pacjentom uniknąć leczenia operacyjnego,jednakże celowe byłoby przeprowadzanie badań klinicznych obejmujących liczną grupę pacjentów.

Opis:
The aim of the study was an assessment of isometric torque (IT) values under static conditions and relative torque (RT) for the plantar flexion muscles (PFM) and dorsal flexion muscles (DFM) and their mutual relations in males 5 years after talocrural joint sprain. IT measurements in PFM and DFM were performed using Biodex System 3. Group I consisted of 20 males on average 5 years after the sprain of the talocrural joint. Group II comprised 23 males with no history of talocrural joint injuries. The angles of measurement were: –15° of dorsiflexion (DF) and 0°, 15°, 30° and 45° for plantar flexion (PF) of the foot. In group I, the IT and RT obtained from PFM of involved leg were statistically significantly lower for most of the measured values of foot angle as compared to the contralateral joint and the results of the control group. The increase in the PF angle resulted in the decrease in IT values obtained from PFM, in favour of DFM. The IT values for PFM and DFM depend on the angle of foot and are represented by two different curves.

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:
Young school-age children are particularly prone to postural defects because they are in a period of development of the spine that is exposed to a number of factors impairing its normal growth. A change in the shape of the spinal column causes a shift in the centre of gravity. Therefore, this study attempted to assess the influence of body posture on distribution of the load transferred by the lower limbs. Methods: For each of the examined children, this study determined the parameters describing the body posture with the use of the photogrammetric method and the parameters describing plantar force distribution. The statistical analyses were performed using the U Mann– Whitney test and the student’s t-test. The correlations between the parameters of the body posture and the parameters describing the foot load distribution were analysed using the Pearson correlation coefficient. These analyses were performed at a statistically significant level of p < 0.05. Results: The tests conducted showed an occurrence of postural defects in about 42% of the subjects and excessively uneven loading of the lower limbs in about 65% of the children. Conclusions: The authors obtained a medium intensity correlation between the analysed parameters for the groups of boys and girls.

Opis:
Purpose: Physiological cross-sectional area (PCSA) reduction of the triceps surae (TS) muscles during aging suggests a proportional loss of torque among its components: soleus, medial and lateral gastrocnemii. However, direct measurements of muscle forces in vivo are not feasible. The purpose of this paper was to compare, between older and young women, isometric ankle joint torque sharing patterns among TS muscles and tibialis anterior (TA). Methods: An EMG-driven model was used for estimating individual muscle torque contributions to the total plantar flexor torque, during sustained contractions of 10% and 40% of maximum voluntary contraction (MVC). Results: Relative individual muscle contributions to the total plantar flexion torque were similar between older and young women groups, for both intensities, increasing from LG, MG to SOL. Muscle strength (muscle torque/body mass) was significantly greater for all TS components in 40% MVC contractions. Increased TA activation was observed in 10% of MVC for older people. Conclusions: Despite the reduced maximum isometric torque and muscle strength, the results suggest small variations of ankle muscle synergies during the aging process.

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:
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:
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.

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:
Wstęp. Stopa jest jedną z najważniejszych struktur anatomicznych ludzkiego ciała. Odpowiada ona głównie za utrzymywanie odpowiedniej pozycji zarówno w statyce jak i w dynamice. Jest to uwarunkowane przez wiele czynników, jednak najważniejszym z nich jest prawidłowe ukształtowanie wysklepienia stopy, które warunkuje jej prawidłowe funkcjonowanie. Każde odchylenie od normy może skutkować zaburzeniem w pełnieniu przez stopę swoich zadań oraz wpływać na funkcjonowanie nawet odległych segmentów ludzkiego ciała. Celem pracy była ocena współzależności pomiędzy wysklepieniem stopy, a sprawnością mechanizmu utrzymywania równowagi w pozycji stojącej. Materiał i metody. W badaniu wzięło udział 48 osób, z czego 21 stanowiły kobiety, a 27 mężczyźni. Ocenę wysklepienia stopy przeprowadzono przy użyciu wskaźnika kątowego Clarke’a, do którego wyznaczenia wykorzystano lustrzany podoskop firmy Podoskop.pl oraz specjalistyczny program komputerowy FREEstep. Ocenę sprawności mechanizmu utrzymania równowagi w pozycji stojącej przeprowadzono na podstawie sześciu prób stabilograficznych. Wyniki. Przeprowadzona analiza statystyczna wykazała istotną zależność między średnią wartością wskaźnika kątowego Clarke’a badanego obunóż, a wynikiem próby stabilograficznej obunóż z zamkniętymi oczami oraz pomiędzy wartością wskaźnika kątowego Clarke’a dla stopy lewej badanego obunóż, a wynikiem próby stabilograficznej obunóż zarówno z otwartymi jak i z zamkniętymi oczami. Wnioski. 1. Istnieje współzależność pomiędzy wartością wskaźnika kątowego Clarke’a badanego obunóż a długością ścieżki parcia stóp na podłoże podczas stania na dwóch KKD. 2. Osoby ze zmniejszonym wysklepieniem podeszwowym stopy mają zmniejszoną sprawność mechanizmu utrzymania równowagi w pozycji stojącej na dwóch KKD zarówno z otwartymi jak i zamkniętymi oczami. Powyższe obserwacje można uogólnić następująco: osoby posiadające bardziej wysklepione stopy lepiej kontrolują równowagę podczas stania na dwóch KKD. 3. Osoby posiadające bardziej wysklepione stopy lepiej kontrolują równowagę podczas stania na dwóch.
Background. The foot is one of the most important anatomical structures of the human body. It is mainly responsible for maintaining an appropriate position, both in static and dynamic conditions. This function is conditioned by many factors, the most important being a normal shape of the foot arch, which determines its proper operation. Any deviation from the norm may result in disruption in the performance of the foot and affect the functioning of even distant segments of the human body. The aim of this study was to evaluate the correlation between the foot arches and the efficiency of the balance mechanism in standing. Material and methods. The study enrolled 48 individuals, of whom 21 were women and 27 men. Evaluation of the foot arches was performed using Clarke's angle index, which was determined with the use of a mirror podoscope produced by Podoskop.pl and a specialist computer program FREEstep. The efficiency of the balance mechanism in the standing position was evaluated on the basis of six stabilographic tests. Results. A statistical analysis showed a significant relationship between the mean value of Clarke's angle index in bipedal standing and the result of the stabilographic test for bipedal standing with eyes closed, and between the value of Clarke's angle index for the left foot in bipedal standing and the result of stabilographic tests for bipedal standing both with the eyes open and closed. Conclusion. 1. There is a correlation between the value of Clarke's angle index of the foot in bipedal standing and the length of the foot pressure path on the ground during bipedal standing. 2. Individuals with a reduced plantar vault of the foot have reduced efficiency of the balance mechanism in bipedal standing both with the eyes open and closed. The above observations can be generalised as follows: individuals with more arched feet have better balance control in bipedal standing. 3. Persons with more arched feet have better balance control in bipedal standing.

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.
