The TBI is calculated similarly to the ABI. The blood pressure of the great toe is divided by the systolic brachial blood pressure. Clinicians can measure the toe pressure by placing a small toe cuff around the great toe and attaching a photoplethysmography probe at the pulp of the great toe tip. The TBI is considered a better test; however, it is not routinely used as a screening tool because of the need for specialized toe cuffs and photoplethysmography probes, limiting widespread TBI use as a “simple” screen.

More recently, IRT was used in conjunction with standard methods of assessing foot, such as the toe pressure measurement for the diagnosis of vascular disorders in diabetic subjects. Ilo et al. conducted a clinical trial of 118 DM subjects and 93 control subjects to assess the application of thermal imaging in foot trauma. Their work reported that mean temperature was highest in DM subjects with neuroischemia. Moreover, the hot regions were presented with high toe pressure, thus suggesting that IRT with other tools such as toe pressure measurement could provide useful screening of vascular disorders in feet (Ilo, Romsi, and Mäkelä, 2020).

Measurement of transcutaneous cutaneous oxygen tension (TcPO2, ≥25 mmHg) and toe blood pressure (≥30 mmHg increases pre-test probability of healing by 25%) may prognosticate the potential for healing. Some studies suggest that toe pressure is more sensitive than ankle pressure in the diagnosis of limb threatening ischaemia. Those with chronic limb-threatening ischaemia are likely to benefit from early revascularisation, either endovascular or, if suitable and medically fit, a surgical bypass, to help treat infection and ulceration.

In the period from 1 May 2018 to 1 September 2019, 62 patients with IC and different stages of PAD were referred to the rehabilitation center. A total of 35 participants were included in the treatment program (Figure 2). The participants mean age was 71.5 years (SD 7.7 years), 57.1% were males and had a mean BMI at 27 kg/m2 (SD 5 kg/m2). The majority of the participants were male (57.1%), retired (71.4%), and current or former smokers (97.1%). Only 31.4% of the patients had a history of previous revascularization procedure. The mean ankle brachial index of the included patient, but excluding the patient with diabetes, was 0.57 (SD 0.13). Out of 35 included, 8 (22%) were known patients with diabetes, where the average lowest toe pressure measured was 44 mm Hg (range 26–67 mm Hg). Details of the included patients are presented in Table 2. Adherence to the training session was high, out of 36 session of SET, majority of patients completed over 90% of the exercises training sessions. The average adherence was 90.8% (SD 6.7%) outcome Data.

Peripheral arterial disease (PAD) is a common disease causing ischemia in the lower limbs due to arteriosclerosis [1]. It is typically diagnosed by toe or ankle blood pressure measurement in combination with brachial pressure measurement and calculating an ankle-or toe-brachial-index. Patients with PAD can have impaired healing of ulcers in the lower extremities, and in severe cases with critical ischemia, amputation may be needed. Healing potential correlates with local skin perfusion pressure (SPP) [2]. Therefore, measuring SPP at different levels in the lower limbs is a useful clinical tool for preoperative determination of amputation level and a valid predictor of wound healing in general. Furthermore, SPP can replace the ankle-brachial index in cases where Moenckeberg’s media sclerosis is present and ankle-pressure assessment therefor unrealiable [3,4]. Distal blood pressure evaluation in these patients can also often be assessed by toe pressure measurements.
Clinical experience with surgical debridement and simultaneous meshed skin grafts in treating biofilm-associated infection: an exploratory retrospective pilot study

A complete medical history was obtained from each patient at admission. General serologic tests, including those for blood glucose and other inflammatory markers, were performed. To evaluate the vascularity of diabetic foot, transcutaneous partial oxygen tension, Doppler wave, and toe pressure were measured. Patients with peripheral arterial disease received percutaneous transluminal angioplasty from an interventional cardiologist. For the management of wound bioburden, deep tissue culture was performed. When necessary, intravenous antibiotics were administered empirically and were then changed according to the results of culture and sensitivity tests. To evaluate neuropathy, a Semmes–Weinstein monofilament test, pin prick test, temperature test, electromyography, and nerve conduction velocity test were conducted. Appropriate off-loadings were provided according to ulcer locations.
