BACKGROUND CONTEXT Although there are some volunteer collision studies reporting the effects of rear impacts on head and neck kinematics, there are few studies detailing the cervical muscle electromyogram response. Moreover, the effect of a rear impact offset to the left on the resultant muscle responses is unknown. PURPOSE The purpose of this study was to determine the response of the cervic...

We report a case of progressive symmetric brachial weakness followed by cervical muscle weakness. The electromyogram confirmed the diagnosis of amyotrophic lateral sclerosis. After 3 years the patient remained able to walk unassisted and without significant bulbar manifestations or upper neuron signs. The concomitant presence of dropped head syndrome and man-in-barrel syndrome in an amyotrophic...

We propose novel ways of interactions using biosignals. We developed a prototype earphone with three kinds of biosignal sensors: pulse wave, electromyogram (EMG) and acceleration sensors. Using this sensor system, we implemented three new applications automatic music selection, tactile and visual communication and automatic metadata annotation. We also present results of preliminary subjective ...
