Abstract:Footwear is an integral part of daily life. Embedding sensors and electronics in footwear for various different applications started more than two decades ago. This review article summarizes the developments in the field of footwear-based wearable sensors and systems. The electronics, sensing technologies, data transmission, and data processing methodologies of such wearable systems are all principally dependent on the target application. Hence, the article describes key application scenarios utilizing footwear-based systems with critical discussion on their merits. The reviewed application scenarios include gait monitoring, plantar pressure measurement, posture and activity classification, body weight and energy expenditure estimation, biofeedback, navigation, and fall risk applications. In addition, energy harvesting from the footwear is also considered for review. The article also attempts to shed light on some of the most recent developments in the field along with the future work required to advance the field.

“…3) used to assess balance was available in multiple sizes to accommodate the foot sizes of the subjects, thereby ensuring the reliability of measurement results. Seven pressure sensors on the insoles of each pair of stabilometer transmitted wireless Bluetooth® data at a sampling frequency of 100 Hz [20,21]. The subject maintained a quiet standing posture for 45 seconds with eyes open and feet apart.…”

Objectives: Foot problems are common in the elderly and are associated with impaired lower limb muscle strength, reduced balance function, and foot pain. We investigated the effect of foot care on these parameters as well as on medical costs in 32 community-dwelling elderlies (mean age 75.3 ± 6.1 years). They were divided into two groups based on pre-intervention fall risk assessed by lower limb muscle strength. In this study, we examined the impact of foot care intervention on medical costs by conducting an analysis on the medical costs of the subjects who had been compensated by the National Health Insurance or by the medical care system for those aged over 75 years. Measurements: Lower limb muscle strength was evaluated by measuring toe-gap force and knee-gap force. Balance capability was evaluated by the trajectory of the length and area of center of pressure (COP) and pressure ratio of toe contact with the ground. Medical costs were compared before and after intervention. Results: Signi cant increases in toe-gap force and knee-gap force were observed after foot care intervention. Post-intervention toe-gap force and knee-gap force were signi cantly lower in the foot pain group than in the foot pain-free group. The toe-gap force and knee-gap force in both groups improved signi cantly after foot care intervention. The subjects who had pain in their feet were signi cantly more likely to belong to the higher fall risk group. There was a reduction in medical costs for the group of the over-75 group. Conclusion: In community-dwelling elderly, foot care improves lower limb muscle strength and balance, which are associated with falls, and reduces medical costs.

Background: In many human postural studies, the foot is considered to be a rigid body. The human foot is composed of the arch structure, which is characteristic in every person and deforms with aging. Foot arch structure is assumed to effect postural control; however, underlying mechanisms remain unclear. The aim of this study was to elucidate the relationship between the structure of the foot arch and postural control in the elderly.
