The AT 53 's two channels can be used for single site, dual site and ratio (A/B) training.

Superior Audio Feedback
Each channel offers a choice of four different audio tones, (piano, continuous, clicks and raw signal). These tones can be selected individually to sound continuously, or above or below the threshold. If desired, you can use the AT 53 's Sustained EMG Feedback Feature: Before audio feedback is provided, the EMG activity must exceed the threshold continuously for either three or five seconds, (user selectable). If the muscle activity drops below this threshold, the timer resets automatically.

Last Value Attained (LVA) Display Feature
The Last Value Attained Feature can display the maximum or minimum EMG level obtained during the session. This can be used to provide a target for increased patient motivation. And, with its auto-ranging numerical display, your patients' EMG readings will never go off-scale -- The AT 53 automatically displays the full range from 0.01 to 999 mV, with no switches to set or adjust.

Summary and Intra-Session Statistics Features
Summary statistics are provided for the entire session and intra-sessional statistics are sampled periodically throughout the session. Both can be recalled and recorded at the end of the session. Statistics collected include: minimum, maximum, mean, standard deviation and the percent standard deviation. Additionally, the AT 53 can calculate the percentage of time your patients were above or below their training threshold.

Portable, both battery or line-powered. Complete with all accessories including a carrying case.
