RESUMEN
Introduction: To analyze the relationship between pain, the fear of falling and functional performance in older people living in a long-stay institution (LSI) in the interior of northeastern Brazil. Methods: A cross-sectional study was conducted with 133 older residents in an LSI in the State of Paraíba. The instruments used for data collection were the Geriatric Pain Measure (GPM), the Falls Efficacy Scale-International (FES-I) and the Short Physical Performance Battery (SPPB). Results: Pain was reported by 57.5% of those evaluated, 48% being classified as chronic pain and presenting an average of 25.2 in the GPM. As for physical performance, assessed using the SPPB, the 133 older residents showed moderate to poor performance, with an average of 6.43 (±2.96) on the scale. By correlating the adjusted GPM values with the FES-I, a weak and statistically significant positive correlation was obtained (ρ = 0.31: p < 0.001). Conclusions: It can be concluded that those who reported pain had a worse performance in the applied tests, in addition to having higher scores on the scale referring to a fear of falling.
