Utility of the ability for basic movement scale II as a prediction method of ambulation ability in patients after the hip fracture surgery.

Background: This study was to investigate whether the Ability for Basic Movement Scale II (ABMS II) at admission of the convalescent rehabilitation ward (CRW) could predict the ambulation ability in patients after hip fracture surgery.

Methods: The data of the ABMS II and Functional Ambulation Category (FAC) of 118 postsurgical patients with hip fracture who were transferred to the CRW were retrospectively analyzed (mean age 82.7 ± 7.9, female/male: 89/29). Binary logistic regression analysis and receiver operating characteristic (ROC) analysis were used to investigate the predictive value of ABMS II for walking ability at discharge.

Results: Spearman's correlation analysis showed that there were significantly positive correlations between the ABMS II score at admission and FAC score at discharge (ρ = 0.70, P < 0.05). Logistic regression analysis showed that ABMS II and BMI can be the predictor in both FAC <4 or ≥4 groups. ROC analysis indicated that an optimal cutoff of 24.5 points of ABMS II score predicted independent walking ability (area under the Curve (AUC) 0.87, P < 0.05).

Conclusions: The ABMS II at admission in CRW can be a prediction method of ambulation recovery for the patients after hip fracture surgery.

Study Design: Retrospective clinical study.
