LIMOS-Br was developed for clinical use, guiding decision-making in rehabilitation and encompassing a significant portion of the core set of rehabilitation information. It is a 45-item instrument that measures the activity component, covering broad aspects of communication, mobility, self-care, cognition, and domestic tasks. The instrument is already utilized in Switzerland and has been validated in Brazil in the form of a questionnaire, facilitating the coding of the International Classification of Functioning, Disability and Health (ICF) and the production of essential health indicators for member countries of the World Health Organization (WHO).

To explore the potential of LIMOS-Br to simultaneously provide relevant information for rehabilitation and for the production of health indicators.

The cross-sectional study was approved by the Ethics Committee and included 100 adult individuals post-stroke with varying levels of impairment and disability. Functionality was measured through patient self-reports using LIMOS-Br, based on interviews conducted by a rehabilitation professional and guided questions specific to the instrument. In cases of moderate to severe aphasia, assistance from proxies was provided. The data were analyzed descriptively.

The information generated by the instrument follows the exact description of the ICF categories and does not require linkage processes. Despite communication and cognitive impairments, the greatest difficulties were related to mobility, particularly dependency and limitations in climbing (d451), changing basic body position (d410), moving around (d455), and walking (d450). For self-care, the activities with the highest difficulty were eating (d550), caring for body parts (d520), dressing (d540), and washing oneself (d510).

The information obtained from LIMOS-Br was easily coded using the categories and the five proposed levels of functionality by the ICF, and was consistent with findings from previous studies on functionality in post-stroke individuals, reinforcing that mobility is a significant restriction in these cases. These findings suggest the need for support and adaptation of the environment to facilitate the participation of these individuals, often involving the necessity of a caregiver. The use of LIMOS-Br should be expanded to other populations to enhance understanding of functionality in different contexts.

LIMOS-Br demonstrates potential to provide essential data for both rehabilitation planning and the generation of health indicators. Identifying difficulties in performing functional activities can support the development of public policies and strategies focused on rehabilitation and accessibility.
