Mendelsohn ME, Leidl DS, Overend TJ, Petrella RJ: Specificity of functional mobility measures in older adults after hip fracture: A pilot study. Am J Phys Med Rehabil 2003;82:766-774.

Objective: To determine the relationships between measures of functional mobility (Timed Up and Go [TUG], Self-Paced Walking [SPW], Berg Balance Scale [BBS]) and global functional status (FIM™ instrument), the motor component of the FIM instrument (motor FIM), and the mobility/locomotor-specific FIM component (ML-FIM) in older patients admitted to an inpatient rehabilitation program after hip fracture.

Design: The TUG, SPW, BBS, and FIM instrument were administered within 24 hr after admission and before discharge to 20 patients undergoing inpatient rehabilitation after a hip fracture.

Results: Significant correlations at admission were found between FIM and TUG scores (r = −0.47; p < 0.05), TUG and motor FIM (r = −0.45; p < 0.05), TUG and ML-FIM (r = −0.58; p < 0.01), FIM and BBS (r = 0.60; p < 0.01), motor FIM and BBS (r = 0.50; p < 0.05), and ML-FIM and BBS (r = 0.45; p < 0.05). At discharge, a significant correlation was found between the motor FIM and SPW (r = −0.49; p < 0.05). Change scores between both the motor FIM and ML-FIM and TUG scores were significantly correlated (r = −0.47, p < 0.05, r = −0.50, p < 0.05, respectively).

Conclusions: The FIM instrument, motor FIM, and ML-FIM may not be specific measures of functional mobility in patients with hip fracture.
