Abstract

Objective: To evaluate the reliability of measurements of foot pressures while walking using the F-scan computerized system with various insole sensors.

Design: Ten healthy subjects were studied. Each used four different pairs of insoles while walking for three 6-second epochs per insole. Peak pressures were recorded at the hindfoot, midfoot, and forefoot and analyzed. Each insole was made of pressure-sensitive 25mm² cells, embedded in protective backing, and scanned electronically every to 50 to 100msec.

Setting and Participants: Conventional tile floor in a gait laboratory on 10 consecutive normal subjects.

Results: The mean ± standard deviation peak pressure recorded at the hindfoot was 11.1 ± 2.0psi; at the midfoot, 3.5 ± 1.5psi; and at the forefoot, 11.3 ± 2.6psi. The intrasubject mean differences were 0.2psi at the hindfoot, 0.4psi at the midfoot, and 0.3psi at the forefoot. The data suggest that variability between different insoles is not significant.

Conclusion: The pressure data show these insoles to be sufficiently reliable for use in patients when knowledge of foot pressure distribution is important for the relief of pain, and for designing and assessing appropriate corrective measures to relieve excessive pressure on the foot and to prevent development of pressure ulcers.

Plantar pressure distribution during running with a self-customized foot orthosis in a home microwave
2021, Journal of Biomechanics
The individualization of a custom-made foot orthosis could provide improvements in plantar loading distribution regarding a prefabricated one. However, not all runners can afford it because of its high cost. A new type of low-cost prefabricated foot orthoses with self-customization could be the solution. The aim of the study was to evaluate if self-customized prefabricated foot orthoses (SCFO) could improve plantar pressure distribution with respect to generic prefabricated ones without customization, during the intense prolonged running. Thirty healthy recreational runners performed two tests of 30 min running on a treadmill, each one with a foot orthosis condition, on different days. Mean peak pressure, pressure–time integral, relative pressure and stance time were measured at the beginning and at the end of the tests. Plantar pressure data were analyzed in nine foot regions. Two-way repeated-measures ANOVAs were performed. SCFO reduced relative pressure in metatarsals (P < 0.005) and lateral heel (P = 0.004), thanks to a greater involvement of arch area in mean peak pressure (medial: P = 0.006 and lateral: P = 0.019) and relative pressure (P < 0.001). In general, prolonged run increased pressures in forefoot, in both foot orthosis, but with lower values in metatarsals with SCFO (P < 0.022), which also helped reduce relative pressure in midfoot (P = 0.007) and medial heel (P = 0.035). Stance time was not modified in any case (P > 0.05). In conclusion, customization and better fit of a low-cost prefabricated foot orthosis can improve plantar pressure distribution during a prolonged run, being a good prevention mechanism for plantar overloading in healthy runners.
Proximal femoral nail shows better concordance of gait analysis between operated and uninjured limbs compared to hemiarthroplasty in intertrochanteric femoral fractures
2016, Injury
The purpose of this study was to compare the results of pedobarographic gait analysis between the patients treated by proximal femoral nail or bipolar partial hemiarthroplasty due to intertrochanteric fractures.
Thirty-seven patients with a minimum 1-year follow-up who had been operated for intertrochanteric fractures were evaluated clinically, radiologically and with pedobarographic gait analysis. Proximal femoral nail had been performed to 21 patients (group A), whilst 16 patients had been operated by partial bipolar hemiarthroplasty (group B). Pedobarographic analysis was performed by measuring plantar pressure, force and contact area values in both static and dynamic manner. Pedobarographic results of operated limb were compared among groups. Same data's also were compared between operated and uninjured limbs in each group to determine any asymmetry on weight-bearing.
Average follow-up period in group A and group B was 36 (12–56) and 30 (12–48) months, respectively. There were no statistically significant differences among groups in terms of age, gender, body mass index, type and side of fracture, follow-up period, leg length discrepancy and postoperative hip scores. When the pedobarographic results of operated limb were compared, group B showed much more plantar force and pressure values than group A, on both static and dynamic evaluations. If the evaluation was taken into consideration to comparison of pedobarographic results between operated and uninjured limbs in each group, we found asymmetry in static load bearing, caused by higher load on uninjured limb in both groups. However, there was no statistically significant asymmetry between operated and uninjured limbs in respect to dynamic pedobarographic parameters for patients in group A. On the contrary, operated limbs in group B exposed much more plantar force and pressure values than uninjured limbs, which indicated asymmetric weight-bearing on dynamic evaluation.
Assessment of pedobarographic parameters can be another way of measuring the results of treatment in intertrochanteric fractures. Uninjured limbs of patients expose much more loading than operated limbs in postoperative static evaluation for both treatment options. However in dynamic evaluation, there is a better concordance of gait analysis between both limbs in patients operated by proximal femoral nail.
Repeatability and reproducibility of the Tekscan HR-Walkway system in healthy children
2014, Foot
This study investigated the repeatability and reproducibility of the HR Walkway system with regards to peak pressure values (PP) and pressure time integral (PTI) in healthy children, ranging between 5 and 18 years of age. Subjects recruited took part in two non-invasive clinical assessments, at baseline and 1 week later. Gait analysis was carried out using the PP box approach, and plantar foot recording was divided into 10 anatomical areas. The PP and PTI was investigated for the left, right and both feet accounted together. Interclass Correlation Coefficient (ICC) test was adopted for statistical analysis. Overall, 30 healthy patients were recruited and 60 appointments were completed, 53.3% (n = 16) were female and 46.7% (n = 14) were male. Mean age was 13.3 years (SD = 4.5), with an age-range of 5–18.6 years old. Results indicated that for all variables tested the repeatability data were ‘good’ ICC for 73.8% (n = 121) and ‘moderate’ ICC for 26.2% (n = 43). For all variables tested, the reproducibility data showed that ‘good’ ICC for 70.7% (n = 58) and ‘moderate’ ICC for 29.3% (n = 24). In conclusion, the HR Walkway system is able to provide repeatable and reproducible data.
Walking assessment with instrumented insoles in patients with lower limb spasticity after botulinum toxin infiltration
2012, Neurologia
El objetivo del presente trabajo es la valoración funcional y cinemática en pacientes con espasticidad de miembros inferiores tras lesión encefálica o medular con indicación de infiltración con toxina botulínica (TBA).
Diez pacientes (11 extremidades inferiores) atendidos en unidad de neurorrehabilitación. Examen clínico, funcional (functional ambulation categories, valoración marcha del Hospital de Sagunto) y biomecánico (plantillas instrumentadas Biofoot/IBV versión 5,0) antes y 3 semanas después de la infiltración con TBA. Estadísticos: prueba de la t para muestras relacionadas de las variables clínicas, funcionales y biomecánicas antes y después de la infiltración. Nivel de significación inferior a 0,05. Modo cualitativo para valorar si los cambios en las variables biomecánicas orientan a una aproximación a los parámetros de normalidad.
La infiltración con TBA mejora el tono muscular, el arco articular y la frecuencia de espasmos (p < 0,01). La población infiltrada muestra un nivel alto de satisfacción con la mejora de los síntomas. No hay cambios funcionales en habilidad para la marcha tras la infiltración. En los parámetros biomecánicos mejora de la cadencia de marcha y la presión máxima en retropié se aproxima a la significación estadística cercana a 0,1.
Con la disminución del tono muscular tras infiltración con TBA, mejoran los síntomas clínicos derivados de esta sin cambios funcionales en escalas de marcha. Los cambios en los parámetros biomecánicos indican la necesidad de ampliar los estudios con plantillas instrumentadas en población con espasticidad tras lesión del sistema nervioso central tratada con infiltración de TBA.
Botulinum toxin A (BTA) improves the kinematic parameters of gait in patients with spasticity of lower limbs, but there are no studies in which kinetic parameters are measured with instrumented insoles. We therefore used instrumented insoles to perform a functional assessment of therapeutic results in patients with lower limb spasticity after brain injury or spinal cord infiltration indicating BTA.
Ten patients (11 lower limbs) seen in a Neurorehabilitation Unit. The tests carried out included clinical examination, gait assessment (Functional Ambulation Categories (FAC); Hospital de Sagunto Gait Scale), and biomechanical assessment (Biofoot / IBV version 5.0), before and three weeks after infiltration with BTA. Statistics: t-test for related samples of clinical variables, functional variables and biomechanical variables before and after infiltration. Level of significance P< .05. Qualitative method to assess whether changes in the biomechanical variables tended toward normal values.
BTA improves muscle tone, joint arch and frequency of spasms (P<.01). The patient sample showed a high level of satisfaction with the improvement in symptoms. There were no changes in walking ability after injection. There were no statistically significant changes in biomechanical parameters, but there was improved gait cadence. The relatively small statistical significance close to P=.1 of the peak pressure in the heel after injection indicates the need for further studies with instrumented insoles in people with spasticity due to central nervous system injury.
With the decrease in muscle tone after infiltration with BTA the clinical symptoms associated with muscle tone improved without any functional changes in gait scales. The changes in the biomechanical parameters show that larger studies using instrumented insoles should be performed in the population with spasticity after a central nervous system injury treated with BTA infiltration.
