Otsubo H, Kishimoto K, Hirano I, Nakano H, Itaya K, Kumaki R, Osumi H. Relationship between cognitive function affecting motor Functional Independence Measure and hypnotics. Jpn J Compr Rehabil Sci 2022; 13: 4-11.
Purpose:
The purpose of this study was to examine the relationship between cognitive dysfunction affecting motor Functional Independence Measure (FIM) and hypnotics.
Methods:
This was a retrospective study involving 509 patients aged ≥ 65 years who were discharged from a convalescent rehabilitation ward.
Results:
Multiple regression analysis was performed with motor FIM efficiency and motor FIM effectiveness (motor FIM-e) as independent variables and the presence or absence of cognitive dysfunction as the dependent variable. The use of hypnotics in patients with cognitive dysfunction showed a positive relationship with motor FIM efficiency (β = 0.147, P = 0.019) and motor FIM-e (β = 0.141, P = 0.026). Multiple regression analyses were performed after further classifying hypnotics by therapeutic class into hypnotics with new mechanisms, non-benzodiazepine (BZ) hypnotics, and BZ hypnotics. Non-BZ hypnotics (β = 0.141, P = 0.021) showed a positive relationship with motor FIM efficiency. Non-BZ hypnotics (β = 0.158, P = 0.009) and BZ hypnotics (β = 0.178, P = 0.003) showed a positive relationship with motor FIM-e, whereas hypnotics with new mechanisms of action did not. In contrast, none of the three combinations of hypnotics showed any significant relationship with either motor FIM efficiency or motor FIM-e in patients without cognitive dysfunction.
Conclusion:
The results suggested that the use of hypnotics in patients with cognitive dysfunction increases motor FIM efficiency and motor FIM-e.
