Abstract
BACKGROUND: The number of chronic musculoskeletal pain sites (nCMSP) is reportedly associated with risk of falls. Older participants in community-based research show a wide range of physical functions, but few studies have focused on the risk of falls in older adults with normal motor function (NMF). Clarification of the effects of pain on dual-tasking performance is also important, given the strong link between falls and dual-tasking. AIMS: The objectives were to investigate the associations between: (1) nCMSP and falls; and (2) nCMSP and dual-task performance in older adults with NMF. METHODS: A total of 112 older adults with NMF (44 men, 68 women; 73.4 ± 4.6 years) were classified as fallers (n = 22) or non-fallers (n = 90) according to their fall history. Musculoskeletal pain in the lower body was assessed using questions ascertaining pain in musculoskeletal sites (back, hip, knee, foot, or toe). Participants were assigned to three pain groups according to nCMSP. Basic physical performances and gait performances (normal gait, fast gait, or dual-task gait) were measured. RESULTS: The nCMSP represented a significant risk factor for falls according to logistic regression modeling after adjusting for the five chair stand test and fear of falls. The nCMSP was not associated with any gait variables. DISCUSSION: Potential fall risk may be increased by nCMSP, even in older adults with NMF. Pain-related reduction in attention resources may not represent a risk factor for falls among older adults with NMF. CONCLUSIONS: The nCMSP represents a potential risk factor for falls in older adults with NMF.
