Therapist assisted body weight supported gait rehabilitation was introduced about 20 years ago. Subsequently, several robotic systems have been introduced for assisted body weight supported gait rehabilitation. However, pelvic assistance is not commonly found in those robotic systems. Lacking of pelvic assistance has several disadvantages. The most obvious(More)
The objective of this work is to study the EMG signals based on hand motions for specified tasks, and different gripping conditions so as to identify patterns of EMG signals. This will allow therapists to identify weak muscles of patients with motor weakness, such as spinal cord injury (SCI) and post-stroke and concentrate on rehabilitation activities which(More)
In this paper, we propose a gait generation concept for rehabilitation, in which GaitGen, a gait pattern generator is introduced. The concept of GaitGen will be explained. GaitGen aims to provide objective gait planning for rehabilitation. Gait-related studies have been carried out for the validation and enhancement of GaitGen. Motion capture system has(More)
Therapists often emphasize selection and design of proper training programs for individual patients in different situations and rehabilitation stages. Thus, in order to cater different patient groups, this paper proposes four assistant control strategies for robotic rehabilitation of gait locomotion: (1) orthosis-free, (2) totally-passive, (3) optimal(More)
Gait pattern planning is an important issue in robotic gait rehabilitation. Gait pattern is known to be related to gait parameters, such as cadence, stride length, and walking speed. Thus, prior before the discussion of gait pattern planning, the planning of gait parameters for natural walking should be addressed. This work utilizes multi-layer perceptron(More)
The objective of this work is the study and analysis of the fundamental issues that constitute the development of a hand rehabilitation system by making use of mechanisms with systematic methodology for objective and quantitative assessment for patients with motor weakness, such as spinal cord injury (SCI) and post-stroke. The goal of the work is to use(More)
Therapist-assisted body weight supported (TABWS) gait rehabilitation was introduced two decades ago. The benefit of TABWS in functional recovery of walking in spinal cord injury and stroke patients has been demonstrated and reported. However, shortage of therapists, labor-intensiveness, and short duration of training are some limitations of this approach.(More)
In this paper, a robotic fish employing a carangiform swimming mode have been developed. The tail fin mechanism with a spring and a movable pin enables a smooth adjustable motion. Experiments conducted in the laboratory aim to study the variation of robotic fish's thrust and velocity with respect to various parameters, which includes the frequency,(More)
In this paper, a methodology for gait rehabilitation, combines over-ground walking, body weight support, pelvic control, and gait assistance are introduced and the integrated platform has been developed. This paper also discusses the gap of state-of-the-art research in gait rehabilitation. Systems like Lokomat and Kineassist were studied and discussed.(More)
In this paper, we introduce a gait generation concept for rehabilitation, namely GaitGen. GaitGen aims to provide objective gait planning for rehabilitation. An established formula of normalized gait parameters has been studied via GAITRite. Thirty subjects are recruited for the GAITRite experiment. L-index is introduced to study the significance of leg(More)
