Test-Retest Reliability and Minimal Detectable Change of Body Function Impairment and Activity Limitation Outcomes Using a Mechatronic Evaluation Designed for Inpatient Stroke Research.

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
Objective: To determine the test-retest reliability and minimal detectable change (MDC) scores for 7 precision measures examining upper extremity strength, reaching ability, and the expression of flexion synergy after stroke. The measurements relied on a mechatronic evaluation designed for time efficiency facilitating implementation in inpatient translational research. Design: Observational, analytical, cross-sectional study. Setting: University research laboratory. Participants: Twenty-five participants (N=25) >6 months poststroke with persistent upper extremity body function impairment and activity limitation were recruited using convenience sampling. Interventions: Not applicable. Main Outcome Measures: Shoulder abduction and elbow extension strength measured as a unit of torque (Nm); normalized reaching distance with the arm under 3 conditions: supported, against gravity, and against 50% of shoulder abduction strength; flexion synergy takeover; and emergence thresholds. Results: Twelve male and 13 female participants aged 56.4 ± 17.8 years with a mean time poststroke of 5.37 ± 7.55 years completed the study. The intraclass correlation coefficients for the outcome measures were as follows: shoulder abduction strength (0.963), elbow extension strength (0.983), supported reaching (0.982), reaching against gravity (0.968), reaching against 50% abduction strength (0.974), flexion synergy takeover (0.919), and flexion synergy emergence (0.949) thresholds. The MDC, overall mean, and standard deviation were calculated as follows: shoulder abduction strength (5.69 Nm, 24.44±10.67 Nm), elbow extension strength (5.66 Nm, 18.53±15.66 Nm), supported reaching (0.07, 0.91±0.20), reaching against gravity (0.15, 0.73±0.30), reaching against 50% abduction strength (0.13, 0.69±0.29), flexion synergy takeover (0.14, 0.91±0.17), and flexion synergy emergence (0.17, 0.56±0.27) thresholds. Conclusions: The mechatronic evaluation, although streamlined from more labor-intensive laboratory evaluations, demonstrates excellent (>0.90) test-retest reliability and MDC scores for 7 precision measures of upper extremity body function impairment (weakness and synergy) and activity limitation (reaching).
