Att 2 Salient Char EMG TVHS.pdf

Specification Need

48 kHz sample rate Better quality signals. More accurate measurements of latency and velocity

AANEM Reference Vales

AANEM norms may be used for BMI, age, gender ranges providing instant diagnostic assessment

High pass frequency of

0.06 Hz

Sympathetic skin response, EEG recordings (Movement related potentials)

Detachable stimulator head

Infection control, cleaning

Constant voltage & constant current mode

User trained on constant voltage

Stimulus duration of

0.01 ms

Near nerve stimulation: Nerve block, stimulation SFEMG

24 bit ADC More modern device Stimulus artifact circuit

Less stimulus artifact

Analog sound Unprocessed sound. No delay.

Autosave data Not loose results and traces. No need to repeat the procedure.

On-line report Faster review of data, and access to traces from the report Multi-modality IONM Offer more services (Cadwell) Dual time base Better recognition of potentials on needle EMG Motor unit number index (MUNIX)

Research studies for ALS

CMAP Scan Research studies for MND Compare NCS responses with previous study

Better documentation of recovery or progression of disease.

Reference pictures with real subjects

Better appreciation of the anatomy for needle EMG

Z score calculation for NCS measurements

Statistical way of assessing the severity of abnormality.

Multichannel liveplay with 360 seconds

Easier off-line review and analysis in difficult cases, e.g. children.

Calculate facilitation within and between trains

Important result to differentiate pre-synaptic from post-synaptic abnormality.

Decrement calculation to any trace

User can select the trace where abnormality is greatest.

Automated long and short exercise test

Study of channelopathies (e.g. myotonia).

Conduction velocity distribution (CVD)

Research to study conduction in slower fibers.

Signal enhancer in sensory NCS

Reduce the stimulation artifact.

Level & peak based jitter analysis

More flexibility in analysis

Replicate and average trial

Demonstrate reproducibility of potential. Reduce noise via averaging.

Faster operation.

Complex traces area Display using multiple time bases, different formats (e.g. raster)

Ultrasound Crystals : 128 to 256 Better resolution EXP probe range 6 – 18 MHz

Single probe for deep and superficial structures.

Battery powered More convenient. Autonomous operation.

Used with multiple EMG systems

Economical

Tablet based No PC. Touch screen.

Export Dicom images Patient record management.

Color Doppler (Not available on some system)

Features implemented better Feature Benefit

Popup menus Faster entry of patient complains and history, less errors, Rollback & Roll forward Recover best response.

Offline averaging Better quality response Edit average Better quality response Anatomy view Easy to select nerve/muscles for testing Automated marking Fewer errors Delete traces with artifacts in SFEMG

Quick. Save time (Adjust the sequential IPI plot limits, rectangle tool))

Delete traces with excessive noise in MMA

Quick. Better quality of averaged potential (Rectangle tool)

Signal enhancer in F wave (On or OFF)

Better recognition of the F waves for measurements.

Maximize a trace window Better visualization of signals Multi-MUP analysis Color coding, 8+ MUPs from a single epoch, merge two MUPs, delete traces with noise, select a MUP from graph. Faster analysis.

SFEMG Edit all borders of sequential IPI plot, Rectangle tool to delete traces.

Faster analysis.

Laryngeal EMG Support voice recordings.

Ultrasound Presets Easier to get to correct settings.
