چکیده

This paper is aimed at presenting an innovative ankle rehabilitation device based on a parallel mechanism. A functional analysis and design are described to obtain a device able to guarantee ankle movement while patient's body remains stationary. Human ankle is a challenging context where a series of joints are highly integrated. The proposed rehabilitation device permits a patient with walking defects to improve his or her gait. The research focuses on plantar-flexion-dorsiflexion movement. The robust design starts from an accurate modelling of ankle movements during walking, assessing motion data from healthy individuals and patients. The kinematics analysis and functional evaluations lead the study and development of the articulated system. In particular, results of simulations support the effectiveness of the current design. A 3D prototype is presented highlighting that the ankle motion is successfully demonstrated.

Repeatability of Ground Reaction Force during Jump-Landing in Volleyball Players with Functional Ankle Instability

Background and Aims: The accurate mechanisms of ankle instability cannot be assessed in the absence of reliable knowledge about ground reaction force (GRF) variables. The purpose of this study was to evaluate the test-retest reliability of GRF variables during forward and lateral jump-landing in volleyball players with functional ankle instability (FAI). Methods: Eighteen professional volle...

Efficacy of Different Types of Foot Orthoses on Postural Control in Subjects With Lateral Ankle Sprain: A Systematic Review

Background and Objectives: Lateral ankle sprain is one of the most common injuries to the musculoskeletal system, especially among active people. This injury causes complex complications, such as recurrent sprain because of reduced postural control. Foot orthoses are among the interventions used to improve postural control in this population. This review aims to investigate foot orthoses to imp...
