Italian Stroke Upper Limb Capacity Scale: Translation, adaptation, and psychometric evaluation

Le résumé fourni par la source

Introduction: The Stroke Upper Limb Capacity Scale (SULCS) assesses poststroke arm function, movement, and rehabilitation potential, aiding in treatment planning and progress monitoring. This study aimed to evaluate the psychometric properties of the newly developed Italian version of the SULCS. Method: Conducted in an Italian neurorehabilitation clinic, this prospective cohort study included 51 stroke patients with moderate-to-severe upper-limb hemiparesis recruited from May 2022 to April 2024. The SULCS was administered twice by different raters on the first day, and once more by the first rater the next day. Additional assessments, including the Fugl–Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Box and Block Test (BBT), were administered on the first day. After 3 and 6 weeks, SULCS administration was repeated with FMA and BBT administration. Results: Intra-rater reliability (Kappa = 0.99, ICC = 0.99) and inter-rater reliability (Kappa = 0.98, ICC = 0.98) were high. Spearman’s correlations with ARAT, FMA, and BBT were ρ = 0.88, ρ = 0.87, and ρ = 0.86, respectively (all p < 0.001). The SULCS showed minimal floor and ceiling effects, making it suitable for clinical and research use. Conclusion: The results suggest that the Italian SULCS can easily be included as a valid assessment tool for Italian occupational therapists.
