OBJECTIVES: To clarify the prevalence and characteristics of pain associated with sarcopenia and to verify the usefulness of evaluation of pain for sarcopenia. METHODS: In total, 759 community-dwelling people (aged 65–79 years) with or without sarcopenia and lower limb pain were classified into 4 groups (NSp, nonsarcopenia; NSpP, nonsarcopenia with pain; Sp, sarcopenia; and SpP, sarcopenia with pain). Body composition, motor function, history of fractures since age 50 years, and number of falls in the past 1 year were compared between the groups. RESULTS: Participant proportions by group were: NSp, 53.9%; NSpP, 42.8%; Sp, 1.3%; and SpP, 2.0%. Participants with lower limb pain showed low single leg standing, walking speed, and 2-step value scores and high 25-question Geriatric Locomotive Functional Scale (GLFS-25) score after adjusting for age, sex, body mass index, and presence of sarcopenia. The SpP group showed lower functional reach test and higher GLFS-25 scores than the Sp group. Regarding the history of fractures since 50 years of age and falls in past 1 year, a high retention rate of fracture was noted in the NSpP group. They also experienced significantly more falls in the past 1 year than those in the NSp group. The SpP group noted more falls and fractures although it was insignificant. CONCLUSIONS: The results indicate that participants with lower limb pain showed declining motor function and a high risk for falls and fractures. Sarcopenia could escalate this risk. Therefore, evaluating patients for both pain and sarcopenia may be useful for risk assessment and treatment.
