Physiological risk of falls, physical and aerobic capacity in community-dwelling elderly

Abstract

Introduction: Falls are multifactorial and are related to the aging process, reduced functional capacity, comorbidities, sensory deficits, muscle weakness, postural instability and decreased protective response. Objective: To verify the correlation between physiological risk of falls and physical and aerobic capacity of the community-dwelling elderly. Method: Participated elderly individuals from the community, aged ≥65 years, without distinction of sex, race, and/or social class. We excluded cognitive impairments, locomotion incapacity, neurological diseases or sequelae, and/or severe pain that prevented the performance of the tests. We evaluated risk of falls (Physiological Profile Assessment - PPA), physical capacity (Short Physical Performance Battery - SPPB) and aerobic capacity (Shuttle Walk Test - ISWT). Results: Participated 59 elderly (71.8±5.0 ys). The mean performance in PPA was 0.4±0.4; SPPB was 10.4±1.7 and ISWT was 281±111.7 meters. PPA presented a moderate and statistically significant correlation (P<0.001) for SPPB (r= -0.53) and ISWT (r= -0.46). Conclusion: There is a moderate correlation between the physiological risk of falls (PPA) and functional (SPPB) and aerobic capacity (ISWT). Preventive measures to reduce the risk of falls should include strategies to increase functional and aerobic capacity. It is suggested the systematic use of SPPB in clinical practice.
