Evidence-based Customized Ankle-Foot Orthosis with Energy Storage
Purpose Three-dimensional printed ankle-foot orthoses (AFO) have been used in stroke patients recently, but there was little evidence of gait improvement. Here, we designed a novel customized AFO with energy storage, named Energy-Storage 3D Printed Ankle-Foot Orthosis (ESP-AFO), and investigated its effects on gait improvement
Virtual synchronous generator of PV generation without energy storage for frequency support in autonomous microgrid
In fact, the swing equation is an important process of VSG, (1) J d ω s dt = T m-T e-D (ω s-ω 0) where J is the moment of inertia (kg·m 2); T m, T e, and D are the virtual mechanical torque (N·m), virtual electromagnetic torque (N·m), and damping coefficient (N·m/rad), respectively; D p is droop coefficient; ω s is the rotor angular frequency of the
Double Support
Double support is a reflection of balance ability and confidence in balance ability, as someone who is unstable on their feet would try to maximize their base of support. For the general adult population, 20% double support is the norm. Table 7: Normative values of % double support for non-diseased elderly men and women.

Energy storing and return prosthetic feet improve step length
Background Energy storing and return (ESAR) feet are generally preferred over solid ankle cushioned heel (SACH) feet by people with a lower limb amputation. While ESAR feet have been shown to have only limited effect on gait economy, other functional benefits should account for this preference. A simple biomechanical model suggests that

Role of the calcaneal inclination in the energy storage capacity of the human foot
The energy storage capacity of the human foot as a passive structure depends on both its geometry and elastic properties. The present study examines theoretically the relationship between the energy stored in the longitudinal arch and the inclination of the calcaneus, when a vertical load is applied. A simple two-dimensional model was used, consisting of
