Simple in-shoe sensors based on film-type sensor materials were developed in this study. Three sensor materials were tested: polyvinylidenefluoride (PVDF), cellulose nanofibrils (CNF) and ElectroMechanical Film (EMFi). Plantar pressure distributions of a subject were measured with the developed in-shoe sensors; each consisting of three sensor channels (lateral and medial metatarsal heads and heel). In addition, piezoelectric sensor sensitivities and crosstalk between the sensor channels were determined. Differences between the tested film-type materials and measured plantar pressure distribution signals were studied...

INTRODUCTION: Pathological conditions such as diabetic foot and plantar heel pain are associated with changes in the mechanical properties of plantar soft tissue. However, the causes and implications of these changes are not yet fully understood. This is mainly because accurate assessment of the mechanical properties of plantar soft tissue in the clinic remains extremely challenging. PURPOSE: To develop a clinically viable non-invasive method of assessing the mechanical properties of the heel pad...

An open fracture of the calcaneus with loss of substance is a challenging injury and requires specialized care, involves high costs, and demands attention despite its lower incidence. The main complications are osteomyelitis, pressure ulcers, and fistulas, as well as pain conditions in the lateral, medial, and plantar regions. This is due to the wide loss of tissue and the change in anatomical conformation of the calcaneus in some cases. However, in cases of flattening of the calcaneus bone, these complications may be prevented or treated successfully...

BACKGROUND: Diabetes is one of the most common chronic diseases in the world and is associated with a life-time risk of foot ulcer of 12-25%. Diabetes related restriction in ankle joint range of dorsiflexion is proposed to contribute to elevated plantar pressures implicated in the development of foot ulcers. METHODS: A systematic search of EBSCO Megafile Premier (containing MEDLINE, CINAHL, SPORTSdiscus and Academic Search Complete) and The Cochrane Library was conducted to 23rd November 2016...

Claudia Giacomozzi, Julie A Stebbins
Plantar pressure analysis is widely used in the assessment of foot function. In order to assess regional loading, a mask is applied to the footprint to sub-divide it into regions of interest (ROIs). The most common masking method is based on geometric features of the footprint (GM). Footprint masking based on anatomical landmarks of the foot has been implemented more recently, and involves the integration of a 3D motion capture system, plantar pressure measurement device, and a multi-segment foot model. However, thorough validation of anatomical masking (AM) using pathological footprints has not yet been presented...

INTRODUCTION: Subjects with sensorial losses present balance deficits. Although such condition is often observed among elderly, there is discussion concerning the dependence on sensorial information for body sway control in the elderly without sensorial losses. PURPOSE: We investigated the effects of foot sensitivity manipulation on postural control during upright standing in young adults and independent elderly (n=19/group). METHODS: Plantar sensitivity was evaluated by esthesiometry, and speed of center of pressure shift data during upright posture were evaluated for each foot using a baropodometer while the subjects were standing with eyes open or closed...

The antiphospholipid antibody syndrome is defined by the presence of antiphospholipid antibodies in patients with recurrent venous or arterial thromboembolism (1). SAPHO syndrome is a rare disease, characterized by specific clinical manifestations of synovitis, acne pustulosis, hyperostosis, and osteitis. It is a disease that manifests with a combination of osseous and articular manifestations associated with skin lesions (2). Venous thrombosis complicating SAPHO syndrome seems to be uncommon with an unclear pathogenesis (3-9)...

Xiaoyou Lin, Boon-Chong Seet
This paper presents a new design of a wearable plantar pressure monitoring system in the form of a smart sock for sensing abnormal relative pressure changes. One advantage of this approach is that with a battery-free design, this system can be powered solely by radio frequency (RF) energy harvested from a radio frequency identification (RFID) reader unit hosted on a smartphone of the wearer. At the same time, this RFID reader can read foot pressure values from an embedded sensor-tag in the sock. A pressure sensing matrix made of conductive fabric and flexible piezo-resistive material is integrated into the sock during the knitting process...

A major purpose of investigating the plantar pressure in patients with pain or those at risk for skin injury is to reduce the pressure below metatarsal heads, specially first and second metatarsal heads. The aim of this article is to evaluate the effects of the socks structures on the changes in plantar dynamic pressure. In this study, seven socks types with different structures for the sole area were produced. The Gaitview(®) AFA-50 system, a force plate, was used to measure the plantar dynamic pressure of 10 participants...

BACKGROUND: While stooping and crouching postures are critical for many activities of daily living, little is known about the balance control mechanisms employed during these postures. Accordingly, the purpose of this study was to characterize the mechanisms driving net center of pressure (COPNet) movement across three postures (standing, stooping, and crouching) and to investigate if control in each posture was influenced by time. METHODS: Ten young adults performed the three postures for 60s each...

BACKGROUND: The histamine H4 receptor (H4R) has attracted a lot of attention in terms of its role in antinociception. The N-Methyl-d-aspartic acid (NMDA) receptor is a well-characterized participant in pain pathways. However, it's influence on H4R signaling is poorly understood. Thus, in the present study we investigated the effect of a selective H4R antagonist JNJ7777120 (25mg/kg) and a NMDA receptor antagonist MK-801 (0.1-10μg) on nociceptive thresholds in a rat acute pain model. METHODS: The influence of intrathecally (it), intracerebroventricularly (icv) and intraplantarly (ipl) administered MK-801 co-injected with JNJ7777120 administered intraperitoneally (ip) was determined in the modified Randall-Selitto paw pressure, the tail flick and plantar tests...

Substantial progress has been made in the operative treatment of Lisfranc fractures, however, the prognosis remains poor. We hypothesized that Lisfranc injuries change the postural control and muscle strength of the lower limb. Both are suggested to correlate with the clinical outcome and quality of life. 17 consecutive patients suffering from a Lisfranc fracture dislocation were registered, underwent open reduction and internal fixation and were followed-up for 50.5±25.7months (Mean±SDM). Biomechanical analysis of muscle strength capacities, postural control and plantar pressure distribution was assessed >6 month postoperatively...
