TM Flow Study

What is the TM Flow study?

The TM Flow study (also known as the TM Flow System) is a cutting-edge diagnostic platform that combines multiple technologies into a single, non-invasive, outpatient test.

It assesses multiple aspects of vascular and ANS function, including:

• Sudomotor (sweat-gland) function analysis, to evaluate small-fiber neuropathy and ANS involvement
• Photoplethysmography (PPG) to estimate skin blood flow and micro-circulatory perfusion via infrared light sensors at the fingertip
• Ankle-Brachial Index (ABI) with pneumoplethysmography to screen for peripheral arterial disease (PAD) and atherosclerosis in the lower limbs
• Autonomic reflex testing (deep breathing, postural changes) to measure the interplay of the sympathetic and parasympathetic systems in real time

The TM Flow study is a streamlined way to detect early abnormalities related to your ANS and vascular health that might otherwise require multiple separate tests. Consequently, the TM Flow study enables earlier detection of underlying dysfunction, allowing intervention to begin sooner.

Who can benefit from a TM Flow study?

The TM Flow study is particularly beneficial for patients who present with symptoms or risk factors suggestive of autonomic nervous system dysfunction, peripheral vascular disease, or small-fiber neuropathy. Specifically, this includes individuals who experience:

• Numbness, tingling, and burning sensations in the hands and/or feet (typical of small-fiber neuropathy)
• Autonomic symptoms such as lightheadedness, dizziness upon standing (orthostatic intolerance), resting tachycardia, syncope, or POTS-type presentations
• Known diabetes mellitus or pre-diabetes/insulin resistance, where early autonomic and vascular changes are common and often underdiagnosed
• Signs or risk of peripheral arterial disease (PAD), such as leg claudication, cold feet, or known cardiovascular disease risk factors
• Chronic pain in the feet, trunk, or extremities, gastrointestinal issues such as abnormal sweating, bladder dysfunction, or sexual dysfunction — all of which may be related to autonomic or small-fiber nerve involvement

Additionally, the TM Flow study may be appropriate when standard lab tests and routine clinical evaluations do not fully explain a patient’s symptoms, and further insight into autonomic or circulatory health is needed.

How long does a TM Flow study take?

The TM Flow study can take less than fifteen minutes. After the test, Dr. Schneider reviews the results and uses them to inform your treatment plan.

Are there risks associated with having a TM Flow study?

The TM Flow study is a non-invasive, low-risk procedure. It does not involve needles, injections, radiation, or sedation. It's a safe, comfortable, and convenient method for assessing autonomic and vascular health.

What are the benefits of a TM Flow study?

The benefits of the TM Flow study include:

• It provides early detection and objective data
• Comprehensive assessment
• Improved treatment outcomes
• It’s quick and non-invasive
