For the evaluation of autonomic dysfunction, syncope, orthostatic intolerance, diabetic
autonomic neuropathy, sympathetically maintained pain, and distal small fiber neuropathy.

• Heart Rate Response to Deep Breathing
• Valsalva Maneuver
• Sweat Measurements
• Head-up Tilt Analysis
• 30:15 Ratio and E:I ratio
• Baroreflex sensitivity
Standardized tests for each patient are compared to normative data and expressed as a
percentile and normal deviate.

Determine threshold detection using natural stimuli
• Thermal (cooling, warming, and heat-as-pain)
• Vibration

Includes
• Thermal vibratory stimulators
• Patient instruction cards for standardized and simple instruction
• Pateint supply kit
• Calibration verification devices to ensure clean data
• Equipment Cart
• PC and printer

Perform standardlized evaluations of:
• Heart Rate Response to Deep Breathing (HRDB)
• Valsalva Maneuver
• Head-up Tilt Analysis
• 30:15 Ratio
• E:l ratio
• Baroreflex sensitivity

Assists in determining the severity and pattern of autonomic disorders, examines the
integrity of the postganglionic sympathetic sudomotor axon, and assists in the diagnosis
of small fiber neuropathy.

• Measures rate in nL/minute and totalized volume in mL
• Measures resting or evoked sweat output from 4 sites
of the body simultaneously
• Highly accurate, specific, and repeatable
• Time efficient; an 11 minute recording is standard
• Compare results to published norms
• Can be added to an existing CASE IV QST
or WR TestWorks heart Rate Variability Testing Lab
