Tokunaga M, Nakanishi R, Kiyota K, Kubota K, Takahashi T, Shigemoto H, Takahashi S, Nakane N, Yonemitsu H. Relationship between motor FIM improvement (corrected motor FIM effectiveness) and age in proximal femoral fractures. Jpn J Compr Rehabil Sci 2014; 5: 131-135.
Objective: The objective of the present study was to determine the differences in FIM improvement (corrected FIM-M effectiveness) in proximal femoral fracture patients due to age.
Methods: The subjects were 886 proximal femoral fracture patients. For the formula, Corrected FIM-M effectiveness = FIM-M gain / (A − FIM-M at admission), we determined values of A that would yield a mean FIM-M effectiveness of roughly 0.65. We divided the subjects into seven groups each covering an age range of five-year increments, and we determined the mean corrected FIM-M effectiveness for each group.
Results: For FIM-M of 13-18, 19-24, 25-30, and 31- 90 points at admission, the value of A was 47, 70, 85, and 91 points, respectively. Corrected FIM-M effectiveness declined with advancing age, especially above 80 years old.
Conclusion: Mean FIM improvement in proximal femoral fracture patients begins to decline at age 80, while it was reported to be at age 70 in stroke patients.
