Autonomic Function Testing (AFT)
Sudoscan: This test evaluates the risk of peripheral neuropathy by using the sympathetic skin response method and calculating 3 parameters for each extremity (hands and feet): 1. Voltage, 2. Latency and 3. Amplitude/latency ratio (A/L ratio). Results are interpreted based on the sudmotor response score (SMR score), which is comprised of 3 analyses: 1)voltage of the sympathetic skin response to electrical stimulation (amplitude) 2)time of response to reach the peak of amplitude (latency) and 3)the A/L ratio. Scores are color coded.
Vasoscan: Vasoscan is an asssessment of Autonomic Nervous System & Peripheral Circulation: - Non-Invasive 5 minute test - Immediate Report &Interpretation.VasoScan is designed to analyze the ANS ( Autonomic Nervous System) function, Stress and Peripheral Blood Circulation. It provides objective data to help assess disorders such as Depression, Anxiety, Sleep Disorder, Poor Concentration, Mental/physical stress degree, chronic fatigue, and blood circulation. The Vasoscan uses infrared light finger sensor which implements LEDs as both light emitter and detector to measure one's pulse wave. A Pulse Wave occurs when the heart pumps and it generates a contour wave that travels along the arterial tree. The wave form is generated from the left ventricular chamber of the heart to the big arota, and is reflected back when the big aorta bifurcates or divides into two arteries.
Intellewave: IntelleWave system is a fully automated cardiac monitoring device that provides quantitative assessment of Heart RateVariability analysis. IntelleWave HRV testing allows physicians to monitor physiological activity and assess the state of a patient's autonomic function through analysis of Spectral Function Components of R-R intervals Variability. HRV testing with IntelleWave system enables physicians to detect specific types of autonomic dysfunction that may be linked to a multitude of clinical diagnoses. Additionally, IntelleWave is a tool for overall, general assessment of a patient's physiology, and as such, provides a comprehensive, in-depth patient evaluation, often missing in standard medical practice. Such an ability to assess one's physiology determines the wide range of IntelleWave's clinical applications and distinguishes it favorably from all other diagnostic devices based on HRV analysis. In the medical field IntelleWave system can be used by health-care providers to objectively confirm or exclude cases of Cardiovascular Autonomic Neuropathy (CAN), Diabetic Autonomic Neuropathy (DAN) and other diseases or malfunctions of the Autonomic Nervous System (ANS). For instance, with the information provided by IntelleWave clinicians are able to recognize cases of beta-blocker overdose or risk of sudden cardiac arrest. Moreover, IntelleWave can monitor ANS activity by providing up to 24 hours of “realtime”quantitative assessment of spectral function components of HRV (HF and LF). IntelleWave includes an Electrocardiogram and a blood pressure measuring device. A variety of data collected during the test (HRV, blood pressure and ECG readings) enables physicians to evaluate a patient's Autonomic Nervous System activity/status.
