“…Any device which can give a digital data representation of how pressure is distributed at the plantar surface of the foot is an important assessment tool in the management of many neuromusculoskeletal conditions like the diabetic foot. This work therefore joins similar studies (Jor et al, 2019;Klimiec et al, 2014;Sneha et al, 2021;Thai et al, 2018;Thimabut et al, 2014) in producing cheaper and easier Plantar pressure analysis devices for use in medical treatment of foot conditions.…”

“…The technology of estimating the pressure distribution on the plantar surface of the foot can help to identify and analyze various pathologies, neuromusculoskeletal anomalities, posture defects as well as efficiency of insoles and footwear designs, etc. (Jor et al, 2019). Unfortunately, most commercially existing ones are expensive (Cost can range from $20,000 to $50,000) and complicated.…”

Digitally estimating the magnitude of the Plantar Pressures (PP) of the foot is an important aspect in the biomechanical management of diabetic foot and is not yet adopted in our clime and many low income countries mostly due to high cost and complexity of existing designs, as well as poor awareness. This study aimed to produce a cheaper, easier to use and internet of things compliant digital plantar pressure estimating device (DPPE) which should be able to detect, estimate and output in-shoe plantar pressure distribution. 10 Force Sensitive Resistor (FSR) were anatomically spread across an ambipedal insole. ESP8266 board was utilized as the microcontroller. Web applications were designed to ensure a smooth communication between the sensors, the microcontroller, the internet and the display units (Computers and Phones). The device achieved ambipedal fitting, Wi-Fi to internet signal transmissions were successful, and the sensors ability to detect and estimate pressure was achieved. The DPPE as produced in this study can help in achieving digital assessment of the PP estimation and its distribution on the foot for clinical evaluations, hence, it is an important tool in the clinical assessment of the DF managements. Use of WiFi as a mode of data transmission is ideal in a post-COVID world of ours as it supports virtual communication.

“…After that, we drew a table similar to that of the flex. The details of this calibration process are alike those of [20]. Obtained results are in a concordance with the conclusions of [20] and show a linear relationship between FSR data and weights up to a value of 80Kgs.…”

This paper presents BoostSole; a smart insole based system for automatic human gait recognition. It consists of a smart instrumented insole connected to the cloud via the patient's smartphone using low-power wireless communication. First, the design of BoostSole is introduced with discussions of sensors choice, placement, calibration, and data communication. Next, an adaptive multi-boost classification algorithm is deployed to accurately identify different gait patterns. The algorithm is fast and lightweight and can be implemented in ordinary smartphones with a small footprint in terms of computational requirements, energy consumption, and communication usage. Raw and ondevice classified data can be securely uploaded to a distant cloud server for continuous monitoring and analysis. Indeed, they can be visualized and exploited by doctors to identify/correct walking habits and assess the risks of chronic pain associated with an abnormal walk. The system has been evaluated on a dataset containing three gait patterns, namely: shuffle walk; toe walking; and normal gait. Obtained results are promising with more than 97% classification accuracy accompanied by low response time and computational demands.

“…The sensor was selected for the experiment after being tested and compared with known previous ex-perimental analysis [16]. For this validation three pairs of high heels (Figure 3A) with low (1 cm), medium (5 cm), and high (9 cm) elevations were used and the obtained data were compared with previous studies on plantar pressure measurement from Cong et al [8], Yung-Hui et al [17] and Gu et al [18] Relativity coefficients of R 2 1 =0.93, R 2 2 =0.99, and R 2 3 =0.99, respectively, were obtained (Figure 3B).…”

This study investigated the feasibility of combined padded metatarsal cup on plantar pressures and stress distribution in the bone alignment of female foot with high heeled footwear during balanced standing. The aim of this study is to redistribute the plantar pressure away from the medial side of the forefoot. A combined padded metatarsal cup (CPMC) was developed from medium soft ethylene vinyl acetate (MSEVA) and very soft ethylene propylene diene monomer (VSEPDM) neoprene sponge. The participants of three categories were selected for the study. The peak plantar pressure and a radiographic assessment of foot musculoskeletal alignment were carried out. The results showed that the magnitude of load on medial forefoot area could be effectively reduced by inserting joint of soft materials on metatarsal region. Hence load on hallux could also be reduced satisfactorily which could resist the hallux valgus deformity. A comparison of conventional system and jointing materials separately with the developed prototype was made and found that the developed prototype of CPMC provides more relaxation of plantar pressure and musculoskeletal safety and confirms more comfort on hypothesis test. The concept of combined padded metatarsal cup should therefore be considered to help in designing musculoskeletal safety footwear.
