The CMAT Advantage™ System enables objective follow-up of vascular and autonomic healing, ensuring that interventions — such as revascularization, debridement, or glycemic optimization — are genuinely restoring perfusion.

Why Serial Assessment Matters

Re-ulceration rates exceed 30% in diabetic patients within a year.

Traditional wound scoring lacks microcirculatory insight. CMAT Advantage™ provides ABI, PPG, and sudomotor data at each follow-up, showing whether tissue oxygenation and nerve recovery are progressing.

Key Follow-Up Metrics

• ABI improvement ≥ 0.1 → successful vascular response
• PPG waveform normalization → restored flow dynamics
• Sudomotor conductance gain > 15% → small-fiber regeneration

Workflow Example

1. Baseline CMAT Advantage™ test at wound intake
2. Repeat every 4–6 weeks until closure
3. Compare automatic trend graphs to guide further referral

Case Snapshot

A 63-year-old diabetic post-angioplasty was followed with CMAT Advantage™. ABI improved from 0.66 to 0.89, sudomotor +20%.

Ulcer closed in 5 weeks, verifying perfusion recovery objectively.

Conclusion

Integrating CMAT Advantage™ into wound follow-up transforms subjective inspection into data-driven circulation management, reducing recurrence and optimizing outcomes.

The Role of Vascular Assessment in Wound Healing Prognosis

Adequate peripheral circulation is one of the most critical factors in wound healing. For patients with chronic wounds — especially those linked to diabetes or PAD — assessing vascular supply to the affected limb provides essential prognostic information.

The CMAT Advantage system from HealthWright Technologies enables physicians to perform ABI and TBI measurements as part of a complete vascular screening. This gives clinicians objective data on blood flow adequacy before, during, and after wound treatment protocols.

Patients with reduced ABI values (below 0.9) or critically low TBI readings may require vascular intervention before wound healing can be expected to progress. Without this baseline vascular assessment, practices risk investing significant resources in wound care management without addressing the underlying perfusion deficit that prevents healing.

The non-invasive nature of the CMAT Advantage test makes it practical to perform repeat assessments at regular intervals. This allows the care team to monitor whether vascular status is improving in response to treatment.

Integrating CMAT Testing Into Wound Follow-Up Protocols

For practices managing wound care patients, adding CMAT Advantage testing to the follow-up protocol creates a structured, evidence-based way to monitor recovery.

Initial vascular screening at the time of wound presentation establishes a baseline. And subsequent testing at defined intervals, such as every 4 to 6 weeks, documents changes in peripheral circulation that correlate with wound healing progress. This data supports clinical decision-making about treatment escalation, specialist referral, or continuation of the current plan.

The CMAT Advantage system also captures autonomic nervous system data, including sudomotor function testing. This matters for diabetic wound patients whose neuropathy may contribute to both wound development and delayed healing. The system combines vascular and autonomic assessment in a single 15-minute test. Practices gain a complete clinical picture that guides more effective wound management. It also supports proper documentation for Medicare and commercial payer reimbursement.

Frequently Asked Questions: Peripheral Circulation Assessment for Wound Follow-Up

How often should peripheral circulation be re-assessed during wound follow-up?

A practical schedule is a baseline CMAT Advantage™ test at wound intake, then repeat testing every 4 to 6 weeks until the wound closes. Re-testing at defined intervals documents whether peripheral circulation is improving in response to treatment and supports decisions about escalation, specialist referral, or continuing the current plan.

Which metrics indicate a wound is responding to treatment?

Three follow-up signals are useful: an ABI improvement of at least 0.1 suggests a successful vascular response, photoplethysmography (PPG) waveform normalization indicates restored flow dynamics, and a sudomotor conductance gain greater than 15% points to small-fiber regeneration. Reviewing these together gives a more objective picture than wound appearance alone.

Is the CMAT Advantage test FDA-approved for wound assessment?

The underlying TM-Flow device is FDA-cleared through the 510(k) pathway, which is the correct designation for this class of diagnostic equipment—not “FDA-approved.” CMAT Advantage measures vascular and autonomic function (including ABI and sudomotor data) to inform clinical decisions; it does not diagnose or treat wounds on its own. See the FDA 510(k) device information page for details.

Why combine vascular and autonomic testing in wound care?

The CMAT Advantage system captures both vascular measurements and autonomic nervous system data, including sudomotor function, in a single 15-minute test. This matters for diabetic wound patients whose neuropathy can contribute to both wound development and delayed healing, so a combined assessment gives a more complete clinical picture than a vascular-only reading.

Does CMAT Advantage testing support reimbursement documentation?

Yes. Performing structured vascular and autonomic screening at defined follow-up intervals produces objective data that supports proper documentation for Medicare and commercial payer reimbursement. Coverage and coding requirements vary by payer—practices should confirm current rules with each plan.
