Influence of application of the inelastic taping in plantar pressure of runners pronators.

Background: The excessive motion of subtalar pronation of the foot, can cause stress and burden in tissues of the region, giving origin to aches and microtrauma. In clinical practice, excessive movement has been limited to the use of techniques of bandages applied to the plantar arch. Objective: Was to analyze the influence of rigid bandage in plantar pressure distribution corridors pronators. Method: This is a randomized clinical trial, blinded, with twenty runners pronators (33±7 y, 71±7 kg, 174±6 cm). Technique was applied bandage (rigid - BR) to support the plantar arch, described as antipronation. Plantar pressure data were collected using the F -scan system in three tests run at 9 km/h being: no bandages, rigid taping. We considered seven areas of pressure for data analysis, performed by means of ANOVA for repeated measures followed by paired t test. Results: BR resulted in significant reductions (p<0.05) in contact pressures and peak pressure rearfoot. Conclusion: Thus, we conclude that BR provided decrease in contact pressures and peak pressure foot, being significant on the hindfoot than in the midfoot.

Physiological Benefits

AbstractHigh plantar pressure has been associated with increased risk of injury. The characteristics of each physical activity determine the load on the lower limbs. The influence of Nordic Walking (NW) technique on plantar pressure is still unknown. The aim of this study was to analyze the differences between plantar pressure during NW with the Diagonal technique (DT) versus Alpha technique (AT) and compare them with the pressure obtained during normal walking (W). The normality and sphericity of the plantar pressure data were checked before performing a two-way repeated measures ANOVA in order to find differences between speeds (preferred, fast) and the gait (NW, W) as within-subject factors. Then, a t-test for independent measures was used to identify the specific differences between NW techniques. The strength of the differences was calculated by means of the effect size (ES). The results demonstrated that during NW with AT at preferred speed the pressure was lower under the Calcaneus, Lateral Metatarsal and Toes compared to the DT group (p = 0.046, ES = 1.49; p = 0.015, ES = 1.44; p = 0.040, ES = 1.20, respectively). No differences were found at the fast speed (p > 0.05). Besides the increase in walking speed during NW (p < 0.01), both technique groups showed lower pressure during NW compared to W under the Hallux and Central Metatarsal heads (F = 58.321, p = 0.000, ES = 2.449; F = 41.917, p = 0.012, ES = 1.365, respectively). As a practical conclusion, the AT technique may be the most effective of the NW techniques at reducing plantar pressure while allowing NW practitioners to achieve the physiological benefits of NW.

Joint Preserving Surgery

The present study aims to evaluate changes in plantar pressure distribution after joint-preserving surgery for rheumatoid forefoot deformity. A retrospective study was performed on 26 feet of 23 patients with rheumatoid arthritis (RA) who underwent the following surgical combination: modified Mitchell’s osteotomy (mMO) of the first metatarsal and shortening oblique osteotomy of the lateral four metatarsals. Plantar pressure distribution and clinical background parameters were evaluated preoperatively and one year postoperatively. A comparison of preoperative and postoperative values indicated a significant improvement in the visual analog scale, Japanese Society for Surgery of the Foot scale, and radiographic parameters, such as the hallux valgus angle. A significant increase in peak pressure was observed at the first metatarsophalangeal joint (MTPJ) (0.045 vs. 0.082 kg/cm2; p < 0.05) and a significant decrease at the second and third MTPJs (0.081 vs. 0.048 kg/cm2; p < 0.05, 0.097 vs. 0.054 kg/cm2; p < 0.05). While overloading at the lateral metatarsal heads following mMO has been reported in previous studies, no increase in peak pressure at the lateral MTPJs was observed in our study. The results of our study show that this surgical combination can be an effective and beneficial surgical combination for RA patients with mild to moderate joint deformity.

Reliable Representation

The number of trials required to obtain a reliable representation of the plantar pressure pattern is an important factor in the assessment of people with insensate feet or the use of plantar pressure data as a basis for fabrication of foot orthoses. Traditionally, the midgait method has been used for the collection of pressure data, but the large number of walking trials required by this method can increase the risk of injury to the plantar surface of the insensate foot. As a result, the two-step method of plantar pressure data collection has been advocated. The purpose of this investigation was to determine the degree of variability in regional plantar pressure measurements using the midgait and two-step methods of data collection. Plantar pressure data were collected from ten volunteers (five men and five women) between the ages of 20 and 35 years in 20 trials using both data-collection protocols. The results of the study indicate that three to five walking trials are needed to obtain reliable regional peak pressure and pressure-time integral values when the two-step data-collection protocol is used. Although either method can be used for pressure data collection, one method should be used consistently when repeated assessments are required.

Increased plantar pressure has been found to be related with greater risk of falling. Although there is evidence suggesting that obesity is linked to foot disorders, the association between obesity and plantar pressure of older adults has been poorly investigated. The purpose of this study was to examine the association between obesity and plantar pressure distribution and to explore its relationship with body fat distribution. Two hundred and eleven older women took part in this cross-sectional study. Body mass index was taken for obesity classification. Whole body, android, and gynoid fat percentage was assessed using dual-energy x-ray absorptiometry. Peak plantar pressure was evaluated during gait using an Emed AT-4 pressure platform. Obese volunteers generated greater peak pressure at midfoot (187.26 kPa) compared to both normal weight (128.52 kPa, p < .001) and overweight (165.74 kPa, p < .001). Peak plantar pressure at midfoot was also greater in overweight compared to normal weight (p < .001). At forefoot, peak pressure was higher in the obese (498.15 kPa) compared to normal weight volunteers (420.41 kPa, p = .007). Additionally, whole body, android, and gynoid fat percentage were significantly associated with peak pressure at midfoot and forefoot. Therefore, clinicians dealing with falls should consider the effect of increased body weight on plantar pressure.

The Relationship

Abstract The relationship between generalized joint laxity and plantar pressure distribution of the foot and the potential implications for lower extremity injury have not been studied.Context: To determine the relationship between generalized joint laxity and dynamic plantar pressure distribution. We hypothesized that individuals with greater generalized joint laxity, or hypermobility, would have greater dynamic medial midfoot pressure and loading during walking than nonhypermobile individuals.Objective: Case control.Design: Institutional biomechanics laboratory.Setting: Participants included 112 female soccer players between 11 and 21 years of age.Patients or Other Participants: Each participant was tested for generalized joint laxity using the Beighton and Horan Joint Mobility Index (BHJMI; range, 0–9) and was categorized as having either high (BHJMI score ≥4) or low (BHJMI score <4) generalized joint laxity. Peak pressure and maximum force were calculated from a dynamic, barefoot plantar pressure distribution system.Main Outcome Measure(s): Peak pressure and maximum force were greater in the 27 participants categorized as having high generalized joint laxity than in the 85 participants categorized as having low generalized joint laxity. The midfoot region exhibited greater loading in participants with high generalized joint laxity than in the other participants. We found an effect of BHJMI classification in the medial midfoot; peak pressure in the dominant (F1,109 = 11.262, P = .001) and nondominant (F1,109 = 14.32, P < .001) sides and maximum force in the dominant (F1,109 = 7.88, P = .006) and nondominant (F1,109 = 9.18, P = .003) sides were greater in the high generalized joint laxity group than in the low generalized joint laxity group.Results: Athletes classified as having high generalized joint laxity demonstrated increased midfoot loading. Delineation of risk factors for medial collapse of the foot, which include hypermobility in athletes, may help clinicians evaluate and prevent lower extremity injury with treatments, such as orthoses.Conclusions:

Plantar Pressure Distribution

Abstract Background: Gender-related differences of plantar pressure distribution during activities should be thoroughly inspected as it can help establish treatment and prevention strategies for foot and ankle problems. In-shoe measurement systems are preferable without space and activity restrictions; however, previously reported systems are still heavy and bulky and induce unnatural movement. Therefore, a slim and light plantar pressure sensor was newly developed to detect the effect of gender difference on plantar pressure during standing and walking.Methods: One-hundred healthy adult volunteers (50 females and 50 males) were recruited. Ten plantar pressure sensors were implanted in a 1-mm thick insole, with a total weight of 29 g. Plantar pressure was recorded with 200 Hz during 3 seconds of standing and while walking 10 steps. The maximum loads during standing and walking were analyzed in each sensor, and the results were compared between different areas of the foot in the antero-posterior direction and the medio-lateral direction and between different time points. The movement of the center of pressure (COP) during walking was also evaluated. Results were compared between genders by converting body weight to 50 kg.Results: The movement of COP was constant for both genders. In all cases, the maximum load was observed on the inside of the foot. Females had a significantly higher peak pressure on the hallux, toes, forefoot, and inside of the foot compared to males while standing and walking (P < .01).Conclusions: A newly introduced in-shoe plantar pressure sensor demonstrated a typical loading transition pattern of the foot. Furthermore, higher plantar pressure in the forefoot was detected in healthy females as compared to males during standing and walking activities.

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.

Foot Orthosis

Background:Higher plantar pressures at the medial forefoot are reported in hallux valgus. Foot orthoses with medial arch support are considered as an intervention in this pathology. However, little is known about the effect of foot orthoses on plantar pressure distribution in hallux valgus.Objectives:To investigate the effect of a foot orthosis with medial arch support on pressure distribution in females with mild-to-moderate hallux valgus.Study design:Quasi-experimental.Methods:Sixteen female volunteers with mild-to-moderate hallux valgus participated in this study and used a medial arch support foot orthosis for 4 weeks. Plantar pressure for each participant was assessed using the Pedar-X®in-shoe system in four conditions including shoe-only and foot orthosis before and after the intervention.Results:The use of the foot orthosis for 1 month led to a decrease in peak pressure and maximum force under the hallux, first metatarsal, and metatarsals 3–5 ( p < 0.05). In the medial midfoot region, peak pressure, maximum force, and contact area were significantly higher with the foot orthosis than shoe-only before and after the intervention ( p = 0.00).Conclusion:A foot orthosis with medial arch support could reduce pressure beneath the hallux and the first metatarsal head by transferring the load to the other regions. It would appear that this type of foot orthosis can be an effective method of intervention in this pathology.Clinical relevanceFindings of this study will improve the clinical knowledge about the effect of the medial arch support foot orthosis used on plantar pressure distribution in hallux valgus pathology.
