Advanced Technology AT53
is an easy-to-use, portable, surface EMG instrument for single site, dual
site and ratio (A/B) monitoring. Simple enough for the EMG novice, yet
featured for the most demanding practitioner. It provides both
easy-to-understand patient feedback and useful statistical information.
Its BUILT-IN MICROPROCESSOR provides
statistical information for most clinical and research applications –
without the size, cost and complexity of fully-computerized systems. And,
with no software to learn, you can use the AT53
EMG the day you receive it. Technology that WORKS FOR YOU.
Patient Oriented Feedback
The most important aspect of EMG feedback is the
quality of information it provides.
Audio: The AT53
EMG uses a speaker (not a tiny piezoelectric crystal) for clear,
easy-to-understand audio feedback. Your patients can easily hear the changes
in their EMG activity.
Audio feedback selections for each channel include: 1)
piano, 2) continuous, 3) clicks, and 4) raw signal. Feedback can be provided
continuously, above threshold or below threshold.
bright, LED numerical and two fifteen segment lightbar displays provide
easy-to-see visual feedback for each channel. The autoranging numerical
display automatically displays the full range of EMG activity from 0.01 to
999 µV, without manual range adjustment.
Additionally, you can select whether the numeric display provides
real-time – or time period averaged feedback every 1, 2, 4, 10 or 60
seconds – making the trend of muscle activity clearer to the patient.
SUSTAINED EMG ACTIVITY
provides audio feedback when EMG activity is sustained above the threshold
for a user-selectable time period.
LAST VALUE ATTAINED (LVA)
continuously updates and displays the maximum or minimum EMG value attained
(as a target for patient motivation) while the lightbar provides real-time
EMG feedback to the patient.
The AT53 EMG provides both summary and intra-session
statistics for the mean, max., min., SD, %SD and the %Time >or
