The plantar surface of the human foot transmits the weight and dynamic force of the owner's lower limbs to the ground and the reaction forces back to the musculoskeletal system. Its anatomical variation is intensely studied in such fields as sports medicine and orthopedic dysmorphology. Yet, strangely, the shape of the insole that accommodates this surface and elastically buffers these forces i...

BACKGROUND This pilot study aimed to assess the differences in center of pressure trajectory in neuropathic patients with steppage gait. Steppage gait has previously been evaluated by several biomechanical methods, but plantar pressure distribution has been much less studied. The purpose of this study was to analyze the changes in center of pressure trajectory using a force plate. METHODS The...

This paper proposes a novel method of estimating walking distance based on a precise counting of walking strides using insole sensors. We use an inertial triaxial accelerometer and eight pressure sensors installed in the insole of a shoe to record walkers' movement data. The data is then transmitted to a smartphone to filter out noise and determine stance and swing phases. Based on phase inform...

For the determination of ground reaction forces in alpine skiing, pressure insole (PI) systems and portable force plate (FP) systems are well known and widely used in previous studies. The purposes of this study were 1) to provide reference data for the vertical component of the ground reaction forces (vGRF) during alpine skiing measured by the PI and FP systems, and 2) to analyze whether the d...

Introduction Orthopaedic insoles are used in sports medicine practice to treat overuse injuries although clinical evidence is still lacking. There are only few randomized controlled trials with male cohorts available [1]. Moreover, biomechanical effects of insoles remain unclear. Besides mechanical effects ("alignment of the skeleton"), sensorimotor effects are discussed suggesting an influence...

We have developed a compact, wireless, wearable, shoe-mounted sensor package that is designed to provide continuous and real-time monitoring of gait for clinical biomotion analysis. This paper discusses the initial design of our hardware, consisting of a sensor-laden insole and a removable instrumented shoe attachment. Information about the three-dimensional motion, relative position, and press...
