With the need for tools that assess microvascular status in diabetic foot disease (DFD) being clear, near infrared spectroscopy (NIRS) is a putative method for noninvasive testing of the diabetic foot. The use of NIRS in patients with peripheral arterial disease (PAD) has extended to its role in studying the pathophysiology of DFD. NIRS generates metrics such as recovery time, deoxygenation, oxygen consumption (VO 2 ), tissue oxygen saturation (StO 2 ), total haemoglobin (HbT), and oxyhaemoglobin area under the curve (O 2 Hb AUC ). NIRS may potentially help the multidisciplinary team stratify limbs as high‐risk, especially in diabetic patients with symptoms masked by peripheral neuropathy. NIRS may be useful for assessing treatment effectiveness and preventing deterioration of patients with PAD.

Joseph et al. (2022) conducted a systematic review in Peripheral artery disease and diabetic foot disease. Near infrared spectroscopy (NIRS) was evaluated. Near infrared spectroscopy (NIRS) may be a useful noninvasive tool for assessing microvascular status, stratifying high-risk limbs, and monitoring treatment in diabetic foot disease.
