Assessing self-reported spontaneous lower-extremity use in individuals with incomplete spinal cord injury: content validity of the Lower Extremity Motor Activity Log (LE-MAL).
Article in Spinal cord series and cases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
STUDY
designA validity study.
objectivesTo assess the content validity of the Lower Extremity Motor Activity Log (LE-MAL) for assessing spontaneous lower-extremity use in individuals with spinal cord injury/disease (SCI/D). Additionally, the remote application of the LE-MAL was tested.
settingCommunity-based video calls (SCIR-Group/UDESC, Brazil).
methodsThe content validity study was conducted based on COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). A panel of end-users composed of individuals with SCI/D and rehabilitation professionals was interviewed about the relevance, comprehensiveness, and comprehensibility of the LE-MAL items by video call. The content validity ratio (CVR) was calculated for each item, and the content validity index (CVI) was calculated for the overall instrument. The items were considered to have adequate content validity if CVR ≥ 0.54 and the instrument to have adequate content validity if CVI > 0.80. Data on the percentage of individuals able to complete the instrument and the time taken to do so were used in the remote application feasibility analysis.
resultsTwenty-six participants were interviewed, 13 individuals with SCI/D and 13 rehabilitation professionals. All items obtained a CVR ≥ 0.54, and the CVI was 0.95. All participants completed the LE-MAL remotely, with a median time of 21 min.
conclusionsThe LE-MAL presents adequate content validity for evaluating the spontaneous use of the lower extremities during mobility activities in real world settings among individuals with incomplete SCI/D. Additionally, LE-MAL is feasible for remote application via video calls.
