Relationship between the Time to Rise from the Floor and Physical Function in Outpatients Visiting an Orthopedics Department

Abstract

[Purpose] In the present study, we examined the relationship between the time to rise from the floor (TRF) and physical function (muscle strength, balance ability, pain, and flexibility). [Subjects and Methods] This study examined 88 outpatients visiting the orthopedics department of our hospital who were aged ≥65 years. Among the subjects, the association of TRF with grip strength, knee extension strength, finger-floor distance (FFD), functional reach test (FRT) results, and the total number of painful joints was assessed. Simple correlation and multiple regression analyses were performed to determine the relationships of TRF with pain and physical function. [Results] Correlation analysis revealed that TRF significantly correlated with age, pain, grip strength, knee extension strength, FFD, and FRT results. In the multiple regression analysis, knee extension strength, FRT results, pain, and FFD were found to independently correlate with TRF. [Conclusion] Our results suggest that the safety and efficiency of the manner in which the elderly rise from the floor affect their lower extremity muscle strength, balance ability, pain, and flexibility.
