“…We do not have our own reliability for the exercise tests but the intra-observer coefficient of variation (CV) for the ABI at rest in our vascular laboratory is 9.4% (typical error of the estimate is 0.06) 36 . Furthermore, the reliability of the exercise tests has been previously reported by several studies: i) Van Langen et al showed that the inter-observer variability of the post-exercise ABI was 21% 37 ; ii) intra-test and test-retest reliability of exercise TcPO2 using a similar protocol that we used has been reported by Abraham and colleagues as excellent 17,18 . Indeed, the correlation coefficient between two tests was r 2 = 0.80 at distal level and intra-class correlation coefficients for the intra test-reliability and test-retest reliability were 0.920[0.846-0.967] and 0.807[0.723-0.868] respectively 17,18 .…”

“…the places of the probe were defined, the room temperature was controlled and the duration of the pre-test heating period was defined) 10 . This standardized methodology associated with the use of the delta from rest of oxygen pressure (DROP) cut-off has improved the reliability of this procedure that was confirmed by two studies 17,18 . Finally, two different teams found similar cut-off values of the DROP 8,10,12,19 8 .…”

Background:The prevalence of exercise-induced ischemia in the asymptomatic limb of patients with unilateral claudication based on history and treadmill evaluation, and with unilateral ipsilateral peripheral artery disease (i.e ankle-to-brachial systolic pressure index <0.90) is unknown.Methods:We detected exercise-induced ischemia in the asymptomatic limb of patients with apparently unilateral claudication. Among 6059 exercise-oximetry tests performed in 3407 nondiabetic and 961 diabetic patients. We estimated the intensity of ischemia in the both limb (buttocks and calves) using the lowest minimum value of the decrease from rest of oxygen pressure (DROP; limb changes minus chest changes from rest), with significant ischemia defined as DROP lower than −15 mmHg.Results:We found 152 tests performed in 142 nondiabetic patients and 40 tests performed in 38 diabetic patients. The asymptomatic limb showed significant ischemia in 46.7% and 37.5% of the tests. Strictly unilateral exercise-induced claudication with apparently unilateral peripheral artery disease was rare (<4% of all tests). However, among these highly selected tests, significant ischemia was found in the asymptomatic limb in more than one-third of cases.Conclusion:The asymptomatic limb of patients with peripheral artery disease should not be considered a normal limb.

“…The effect of both standing and walking on TcPO2 levels while using a liner remains unclear. For persons without an amputation, exercise TcPO2 levels differ from resting TcPO2 levels by up to 50 mmHg [46][47][48][49].…”

Background In our clinic, a substantial number of patients present with transtibial residual limb pain of no specific somatic origin. Silicone liner induced tissue compression may reduce blood flow, possibly causing residual limb pain. Thus, as a first step we investigated if the liner itself has an effect on transcutaneous oxygen pressure (TcPO2). Methods Persons with unilateral transtibial amputation and residual limb pain of unknown origin were included. Medical history, including residual limb pain, was recorded, and the SF-36 administered. Resting TcPO2 levels were measured in the supine position and without a liner at 0, 10, 20 and 30 minutes using two sensors: one placed in the Transverse plane over the tip of the Tibia End (= TTE), the other placed in the Sagittal plane, distally over the Peroneal Compartment (= SPC). Measurements were repeated with specially prepared liners avoiding additional pressure due to sensor placement. Statistical analyses were performed using SPSS. Results Twenty persons (9 women, 11 men) with a mean age of 68.65 years (range 47-86 years) participated. The transtibial amputation occurred on average 43 months prior to study entry (range 3-119 months). With liner wear, both sensors measured TcPO2 levels that were significantly lower than those measured without a liner (TTE: p < 0.001; SPC: p = 0.002) after 10, 20 and 30 minutes. No significant differences were found between TcPO2 levels over time between the sensors. There were no significant associations between TcPO2 levels and pain, smoking status, age, duration of daily liner use, mobility level, and revision history.
