Co-activation of ipsi- and contralateral muscle groups during contraction of ankle dorsiflexors.

Seventeen adult, healthy subjects, age 38.4 +/- 0.24 years (mean +/- SEM) 7 of which were females, were studied.

Microcomputer-based portable long-term spasticity recording system.

A device for long-term monitoring of muscle activity (EMG) with surface electrodes and method of its application are described in this paper. This device is called a microcomputer two-channel EMG monitor. The device can be used for up to 24 h monitoring of EMG activity, followed by data transfer to a host computer for signal analysis.
