Objective: The aim of this study was to determine the intra-rater repeatability and inter-rater reproducibility of the Mobility Scale and Ruler for post-stroke assessment during hospitalization. Method: A consecutive sample of 58 patients was assessed by two independent and blinded physical therapists (A and B) on the same day (inter-rater reproducibility). For repeatability analysis, therapist A assessed the patients twice, with a five-minute interval between assessments. The Kappa statistic was used to analyze reliability. Results: The mean age of participants was 62.7 (±14.5) years, and 60.34% were male. Ischemic stroke was identified in 88% of the cases, with mild severity (median NIHSS of 3; IQR 4). Assessments were performed 12.5 (±11) days post-stroke. Regarding mobility level, 33 (57%) patients were able to ambulate independently, reaching level 12 on the Scale. Repeatability for both the Mobility Scale and Ruler yielded a Kappa of 1.00 (p<0.001). Inter-rater reproducibility showed Kappa values of 0.928 (p<0.001) and 0.957 (p<0.001), respectively. Conclusion: The Mobility Scale and Ruler demonstrate high reproducibility in assessing mobility in post-stroke patients during hospitalization and can be used both by the same professional to monitor patient progress and by different professionals at various points during the hospital stay.
