The key point of post-stroke rehabilitation is that exercices and therapy must begin as soon as possible after stroke in order to let the survivors regain their body movement functions. By playing the EMG-driven computer game, the patients can locate disused body parts and start training their muscles even when they have to stay on beds during the early stage of rehabilitation. Wearable EMG nodes...
The article investigated whether joint postures affect index finger muscle activation patterns. Ten subjects attempted to produce submaximal isometric forces in six orthogonal directions (palmar, dorsal, abduction, adduction, distal and proximal) at each of 9 different joint postures. Activation patterns were recorded from intramuscular electrodes inserted into 6 of the index finger muscles. Post...
The objective of this work is to study the functional hand strength for ADL rehabilitation tasks based on EMG signals and gripping/pinch force measurement via multivariate data analysis (MVA): Principal Components Analysis (PCA) and Projections to Latent Structures (PLS). The study allows us to identify weak muscles of patients with motor weakness, such as spinal cord injury (SCI) and post-stroke...
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...
We report on a wireless, electromyography (EMG)-based, force-measuring system developed to quantify hand-applied loads without interfering with grasping function. A portable surface EMG device detects and converts to voltage output biopotentials generated by muscle contractions in the forearm and upper arm during hand-gripping and traction activities. After amplifying and bandpass filtering, our radio...
