Relationship between activity of daily living and motor function in the community-dwelling elderly after hip fracture

Abstract

Aim: To clarify the relationship between ADL and motor functions in 44 community-dwelling elderly patients with hip fracture. Methods: The questionnaire comprised items on BADL, IADL, ability to walk, and certification for long-term care. The assessment of motor functions included grip strength, knee extension strength, 10m walking time, TUG, FRT, and Romberg rate and shift length of the center of gravity measured by a stabilometer. Based on these tests, relationships between the motor functions and ADL were evaluated in elderly patients after hip fracture. Results: Significant correlations were found between BADL and grip strength, knee extension strength, and FRT. As for IADL, significant correlations were found with grip strength, knee extension strength, 10-m walking speed, TUG, FRT, and MMSE items. Similarly, regarding ability to walk and the certification of long-term care, significant correlations were shown with grip strength, knee extension strength, 10m walking speed, and MMSE items. Conclusion: The relationships between ADL and motor functions were confirmed in community-dwelling elderly patients with hip fracture. The parameters related to muscle strength and balance ability that were assessed in this study are those that can be improved through constant training after discharge from hospital. The validity of these parameters as the indices for future intervention studies to assess the maintenance and improvement of ADL after discharge and prognosis was indicated.
