Relationship between physician-judged functioning level and self-reported disabilities in elderly people with locomotive disorders

Abstract

Locomotive disorders due to musculoskeletal involvement are one of the main causes requiring long-term care services in aging Japan. "Locomotive syndrome (LoS)" is a concept referring to the condition under which people require assistance from others or at risk in future. The object of this study is to examine the relationship between self-reported measure and physician-judged degrees on ADL disability in elder people with locomotive disorders. In a cross-sectional study, 711 patients who were aged 65years old or more were recruited from 49 outpatient clinics and hospitals. We investigated ADL disabilities by self-reported questionnaire (Geriatric Locomotive Function Scale-25: GLFS-25) and physician-judged grading (Locomotive Dysfunction Grade: LDG) and examined the relationship between these two. We classified the severity of locomotive disability by clinical phenotype into six grades: LDG Grade 1 (N=77), Grade 2 (213), Grade 3 (139), Grade 4 (162), Grade 5 (78), and Grade 6 (42). The mean of GLFS-25 was 25.9. The mean of GLFS-25 was 5.68 for Grade 1, 14.33 for Grade 2, 22.34 for Grade 3, 35.40 for Grade 4, 43.25 for Grade 5, and 60.24 for Grade 6. Significant differences of GLFS-25 scores were found between adjacent LDGs. Physician-judged grade of locomotive dysfunction was significantly related to self-reported assessment scale on ADL disability. Physician-judged dysfunction grade is readily administered scale and useful to assess the severity of locomotive dysfunction. Self-reported scale provides precise information on ADL disabilities due to locomotive organ dysfunction and is useful to develop intervention programs.
