Relative Aerobic Load of Daily Activities in Individuals with Lower Limb Amputation: A pilot study.
Article in Canadian prosthetics & orthotics journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIndividuals with lower limb amputation (LLA) often experience reduced physical capacity and increased aerobic demands during activities of daily living (ADL), which may impact participation and quality of life. Measuring the relative aerobic load of ADL is essential to set realistic rehabilitation goals, however data on short and non-steady-state ADL tasks in this population are limited.
objectivesTo evaluate the feasibility of a newly developed protocol for assessing the relative aerobic load of five selected ADL tasks in individuals with LLA, and to determine the applicability of the excess post-exercise oxygen consumption (EPOC) method for these measurements. METHODOLOGY: Six individuals with unilateral LLA (mean age 59 ± 9 years; five males), including three with transtibial, one with knee disarticulation, and two with transfemoral amputation, all classified as K2-K3 ambulators, were recruited for this pilot study and underwent a cardiopulmonary exercise test (CPET) during the first assessment session. During the second assessment session, within a two-week interval, participants were asked to perform five standardized tests reflecting ADL tasks: the 6-Minute Walk Test (6MWT), Timed Up and Go Test (TUGT), Glittre ADL test, stair ascent, and stair descent. Oxygen consumption was measured using the COSMED K5 system. For each task, average oxygen consumption was computed as the total oxygen uptake during activity and recovery (EPOC) divided by total time, and relative aerobic load was defined as percentage of first ventilatory threshold (%
findingsThe protocol showed to be feasible and no (serious) adverse events occurred during the study and 5 out of 6 participants were able to complete the protocol, demonstrating its practicality. The EPOC method was successfully applied to both short and longer-duration ADL tasks. The results showed relative aerobic loads exceeding 100%
conclusionThis protocol enables the assessment of relative aerobic load in a heterogeneous group of individuals with LLA and highlights the importance of individualized assessment. Given the large variability in
