The feasibility to assess sensory integration in ageing: beyond the cerebral cortex

<ns5:p>Background The global aging population will continue, with significant implications as the growing numbers of people with neurocognitive disorders. The evaluation of Sensory Integration (SI) beyond the cerebral cortex, focusing on subcortical sensory organization systems (tactile, vestibular, and proprioceptive), is fundamental for cognitive functioning (emotional regulation, awareness, attention, and memory). Objectives To adapt and validate the content of the Physical Assessment Scale from the Schoeder-Block-Campbell Psychiatric Sensory Integration Evaluation (SBC-PAS), to measure SI for older adults (OA), and to evaluate in a prospective pilot study its feasibility and safety for the aged population. Methods Based on the guidelines of the International Test Commission Guidelines for test translation and adaptation. The SBC-PAS scale was translated; its content was validated through an expert panel, and the feasibility and safety of its application were explored with an OA pilot study. Results Following the adaptation and validation, changes were made in 16 sections of the vestibular-proprioceptive dimension. The agreement percentages (67% - 89%) and concordance index (0.49 - 0.69) for the evaluated criteria ranged from moderate to substantial. After integrating the suggested changes, the feasibility study revealed that the SBC-PAS was applied within 90 to 190 minutes. We saw the need for specific spatial conditions, examiner training, and participant support. Conclusions We evaluated the adaptation, content validity, and feasibility of the SBC-PAS to assess SI in OA. Feasibility findings add evidence for its application in real-world settings.</ns5:p>
