Stroke-induced hemiparetic gait is characteristically asymmetric and metabolically expensive. Weakness and impaired control of the paretic ankle contribute to reduced forward propulsion and ground clearance - walking subtasks critical for safe and efficient locomotion. Targeted gait interventions that improve paretic ankle function after stroke are therefore warranted. We have developed textile...

This paper puts forward a real-time angular tracking (motion capture) system for a low cost upper limb exosuit based on sensor fusion; which is integrated by an elastic sleeve-mitten, two inertial measurement units (IMU), two flex sensors and a wireless communication system. The device can accurately detect the angular position of the shoulder (flexion-extension, abduction-adduction and interna...

OBJECTIVE The aim of the study was to evaluate the effects on common poststroke gait compensations of a soft wearable robot (exosuit) designed to assist the paretic limb during hemiparetic walking. DESIGN A single-session study of eight individuals in the chronic phase of stroke recovery was conducted. Two testing conditions were compared: walking with the exosuit powered versus walking with ...

Stroke-induced hemiparetic gait is characteristically slow and metabolically expensive. Passive assistive devices such as ankle-foot orthoses are often prescribed to increase function and independence after stroke; however, walking remains highly impaired despite-and perhaps because of-their use. We sought to determine whether a soft wearable robot (exosuit) designed to supplement the paretic l...

The variable stiffness exosuit has great potential for human augmentation and medical applications. However, the model of mechanism in exosuits is far from satisfactory accurate prediction control friction force. This paper presents a lower limb exosuit, verifies its performance, identifies applicability. force was established by Coulomb hypothesis. equivalent coefficient, which core parameter ...

hypertonicity is the most common type of cerebral palsy consists of 85% of the affected children. it has a very complex nature making intervention and management very difficult. this article tries to make reader familiar with various types of intervention and introduce a new intervention process to help clinicians decide better. literature was reviewed with two criteria including: identifying v...
