ABSTRACT
BACKGROUND:
Community-dwelling older adults experiencing hip fracture often fail to achieve adequate walking capacity following surgery and rehabilitation. Effects of psychological factors on post-fracture walking capacity are poorly understood. Accordingly, this paper investigates effects of psychological resilience on observed walking capacity measures in older adults following hip fracture, controlling for important covariates.METHODS:
Data were drawn from the Community Ambulation Project, a clinical trial of 210 community-dwelling adults aged ≥60 years who experienced a minimal trauma hip fracture and were randomized to one of two 16-week home-based physical therapist-guided interventions. Psychological resilience was measured at study baseline using the 6-item Brief Resilience Scale (BRS); scores were classified into groups in order to distinguish levels of self-reported resilience. Walking capacity was assessed at study baseline and 16 weeks later using 4-Meter Gait Speed (4MGS), 50-Foot Walk Test (50FWT), and 6-Minute Walk Distance (SMWD). In multivariate analyses of covariance in which 16-week follow-up values of each walking measure were outcomes, covariates included clinical trial arm, gender, age, and baseline values of walking measure corresponding to the outcome; body mass index; depressive symptom severity; degree of psychological optimism; cognitive status; informal caregiver need; and days from hospital admission to randomization.RESULTS:
Increases between baseline and 16 weeks later in mean gait speed in meters/sec (m/s) and walking distance in meters (m) in 4MGS, 50FWT and SMWD were 0.06 m/s (p = 0.061), 0.11 m/s (p < 0.01), and 25.5 m (p = 0.056) greater, respectively, in the most resilient BRS group compared to the least resilient BRS group.CONCLUSION:
Higher levels of psychological resilience were associated with greater walking speed and distance. Psychological resilience represents a potentially clinically important pathway and intervention target, toward the goal of improving walking capacity among older adults known to have substantial residual disability following hip fracture.Palavras-chave
