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...

Methods Fifteen patients with midfoot arthritis aged between 20 and 60 years participated in the study. Foot function index (FFI) was assessed to evaluate pain before and after the walking activity. Lower leg muscle activity, GRF and gait cycle time during walking were measured under two conditions: “shoe only”, and “shoe with FCF insole”. Electromyography (EMG) activities of the tibialis anter...

We are developing a wireless system that measures online the forces between foot and insole with a low-cost laminated capacitive sensor matrix. This measurement system can be utilized to monitor the timing and movements of the legs of an athlete during throwing, jumping and running in various sports events. The measured data is intended to be used to improve coaching. We chose the javelin throw...

BACKGROUND Pronated foot posture is associated with many clinical and biomechanical outcomes unique to medial compartment knee osteoarthritis (OA). Though shoe-worn insole treatment, including lateral wedges, is commonly studied in this patient population, their effects on the specific subgroup of people with medial knee OA and concomitant pronated feet are unknown. The purpose of this study wa...

Foot pain is a common musculoskeletal disorder. Orthotic insoles are widely used in patients with foot pain. Inexperienced clinicians have difficulty prescribing orthotic appropriately by considering various factors associated the alteration of alignment. We attempted to develop deep-learning algorithms that can automatically prescribe and assess their accuracy. In total, 838 were included this...

Knowledge of the plantar foot shape alteration under weight bearing can offer implications for the design and construction of a comfortable and functional foot support. The purpose of this study was to quantify the change in three-dimensional foot shape under different weight-bearing conditions. The plantar foot shapes of 16 normal feet were collected by an impression casting method under three...

Foot-related problems are prevalent across the globe, and this issue is aggravated by presence of diabetes mellitus. Diabetic-foot-related issues include extreme foot pain, plantar corns, diabetic ulcers. To assess these conditions, accurate characterization pressure required. In work, an in-shoe, low-cost, multi-material measuring insole, based on a piezoresistive material, was developed. The ...

This study assessed human kinetics in relation to golf shoe outer sole design features during the golf swing using a driver club by measuring both within the shoe, and beneath the shoe at the natural grass interface. Three different shoes were assessed: metal 7- spike shoe, alternative 7-spike shoe, and a flat soled shoe. In-shoe plantar pressure data were recorded using Footscan RS Internation...
