Arthroscopic Capsular Release of the Ankle Joint

Arthroscopy Techniques, 2016
Adhesive capsulitis of the ankle is also known as frozen ankle and results in marked fibrosis and contracture of the ankle capsule. Arthroscopic capsular release is indicated for symptomatic frozen ankle that is resistant to conservative treatment. It is

Real‐Time Control of a Humanoid Robot for Whole‐Body Tactile Interaction

Advanced Intelligent Systems, EarlyView.
Inspired by human tactile interaction, this work integrates large‐area artificial skin feedback (force and proximity) into real‐time quadratic programming control for humanoids. This enables robots to leverage distributed sensing to manage forces, safely move around unknown and dynamic obstacles, and robustly handle objects with uncertain geometry ...

Review paper Total ankle replacement – surgical treatment and rehabilitation

Rheumatology, 2015
Functions of the ankle joint are closely connected with the gait and ability to maintain an upright position. Degenerative lesions of the joint directly contribute to postural disorders and greatly restrict propulsion of the foot, thus leading to ...

A Miniature Rotary Electrostatic Clutch for Assigning Multi‐Degrees of Freedom to Insect‐Scale Robots

Advanced Intelligent Systems, EarlyView.
Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.
