The Myolab II was specifically designed for use in fitting and troubleshooting the Utah Arm and ProControl 2 myoelectric prostheses. The adjustable gain feature allows the device to test and train muscle EMG for any single or dual-site myoelectric control system. When used with the Utah Arm, troubleshooting EMG signals is easy because signals can be monitored while the prosthesis is operating, using the supplied T-cable. The Myolab’s easy-to-read dials and audio signals help patients learn to use their myoelectric prosthesis quickly and easily.
