The inclusion of robotic systems in physiotherapy allows developing new solutions for the rehabilitation and support of disabled people. Our research addresses the core problem for the advancement of such applications: the availability of a human machine interface offering intuitive control of robotic devices. In this paper we present an EMG-driven model of the human lower limb based on that previously...
Motor imagery-based brain computer interface (BCI) technology has motor rehabilitation as one of its main fields of application. The use of a BCI as a neuroprosthetic for paralyzed limb motor restoration implies normally absence of muscle activity. It is still an open question whether residual motor activity in healthy individuals or in patients causes a bias in the modulation of a motor imagery-based...
Restoring walking functions will greatly improve the foot-drop patients' life quality. In this work, we sampled 10 healthy subjects' gait data when walking in 4 different stride frequency overground and developed a dynamic Functional Electrical Stimulation (dFES) system for foot-drop patients' walk training, using the processed tibialis anterior (TA) muscle EMG signal. The data sampled under the new...
In this work we have examined the effect of functional electrical stimulation (FES) in the management of drop foot in stroke subjects with surface electromyographic (sEMG) analysis from the tibialis anterior (TA) muscle. Ten subjects were assigned to FES therapy combined with conventional stroke rehabilitation program 5 days a week, 60 min a day, for 12-weeks in clinical settings. Baseline and post-treatment...
In this article the design of a new upper limb rehabilitation system will be presented. A lightweight, modular, and portable system is achieved by the combination of electromyographic (EMG) control, functional electrical stimulation (FES), and the use of miniaturized flexible fluidic actuators (FFA) integrated in an elbow orthosis. First, the state of the art of upper limb rehabilitation devices will...
We developed an interface to the commercial video game Guitar Heroreg III using surface electromyography (EMG) to create a novel training and evaluation device for upperextremity amputees. Rather than pressing the keys with onepsilas fingers as in the normal game, in our modified version a user merely flexes his or her index, middle, or ring finger muscles, and the resulting myoelectric activity is...
The demand for rehabilitation robots is increasing for the upcoming aging society. Power-assisting devices are considered promising for enhancing the mobility of elderly and disabled people. Other potential applications are for muscle rehabilitation and sports training. The main focus of this paper is to control the load of selected muscles by using a power-assisting device, thus enabling ldquopinpointedrdquo...
Robot and functional electrical stimulation (FES) techniques have been used for improving motor functions after stroke respectively. In this work, we aimed to examine the combined effects from Robot and FES in post-stroke wrist rehabilitation. We developed a new electromyography (EMG)-driven FES-robot system with a control algorithm, which was interactive to the voluntary motor inputs from persons...
Current skeletal muscle conditioning is typically performed by application of a steady force (load). However, as confirmed by whole-body-vibration applications, the involvement of neuromuscular reflex due to load variations plays an important role in muscular conditioning. Therefore, in this paper we present a prototype for muscular conditioning where the loading force, which is generated by an electromagnetic...
A summary of the design and functionality of a robotic workstation that has been constructed for use by stroke patients in order to improve voluntary control of their impaired arm is first given in this paper. The patient's task will be to track an elliptical trajectory using voluntary control with the addition of surface FES applied to muscles in their shoulder and arm. This work then comprises results...
