Reliability and validity of daily physical activity measures during inpatient spinal cord injury rehabilitation.
Article in SAGE open medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectivesTo assess the test-retest reliability and convergent validity of daily physical activity measures during inpatient spinal cord injury rehabilitation.
designObservational study.
settingTwo inpatient spinal cord injury rehabilitation centres. SUBJECTS: Participants (n = 106) were recruited from consecutive admissions to rehabilitation.
methodsPhysical activity during inpatient spinal cord injury rehabilitation stay was recorded on two days via (1) wrist accelerometer, (2) hip accelerometer if ambulatory, and (3) self-report (Physical Activity Recall Assessment for People with Spinal Cord Injury questionnaire). Spearman's correlations and Bland-Altman plots were utilized for test-retest reliability. Correlations between physical activity measures and clinical measures (functional independence, hand function, and ambulation) were performed.
resultsCorrelations for physical activity measures between Day 1 and Day 2 were moderate to high (ρ = 0.53-0.89). Bland-Altman plots showed minimal bias and more within-subject differences in more active individuals and wide limits of agreement. None of these three physical activity measures correlated with one another. A moderate correlation was found between wrist accelerometry counts and grip strength (ρ = 0.58) and between step counts and measures of ambulation (ρ = 0.62). Functional independence was related to wrist accelerometry (ρ = 0.70) and step counts (ρ = 0.56), but not with self-report.
conclusionThe test-retest reliability and convergent validity of the instrumented measures suggest that wrist and hip accelerometers are appropriate tools for use in research studies of daily physical activity in the spinal cord injury rehabilitation setting but are too variable for individual use.
