PURPOSE: Exercise transcutaneous oxymetry (PtcO2) can argue for a vascular origin of exercise-related pain in atypical unusual localisations, such as lumbar, thigh or foot pain. We use 5 probes as a standard for treadmill PtcO2 tests. Recent commercially available devices now include up to 8 probes. We aimed at analysing the potential interest of positioning a 6th probe on the area of unusual localisation during exercise PtcO2 tests.
METHODS: We retrospectively analysed our data with a 6-probes device, using as a standard: one probe on the chest, one on each buttock and one on each calf. The sixth probe was positioned either: in the lumbar median position (n=342), on the anterior lower part of the thigh (n=391) or on the dorsum of the foot (n=155) in patients complaining exercise-induced pain including the back, thigh or foot respectively. Results on the sixth probe at the limb were compared to result of the standard adjacent probe. A positive test (abnormal result) was defined as a minimal value of the DROP-index lower than minus 15 mmHg.
RESULTS: Prevalence of positive results on the 6th probe with negative results on the adjacent standard probe was 2.3% at the lumbar site, 3.8% at the thigh and 12.3% at the foot level.
CONCLUSIONS: Atypical localisations are rarely but sometimes associated to isolated positive exercise PtcO2 results and may justify the use of more than 5 probes in some patients, specifically for foot pain.
