Abstract

Introduction

To investigate the validity of Barthel Index (BI) compared with de Morton Mobility Index (DEMMI), EuroQol-visual analog scale (EQ-VAS), 2-min walk test (2MWT), and timed get-up-and-go test (TUG), and to evaluate the responsiveness of all outcome measures for assessing functional recovery in older patients who underwent hemiarthroplasty after femoral neck fracture.

Material and method

Eighty-one femoral neck fracture patients who were enrolled in a study evaluating functional recovery after bisphosphonate therapy during 2013 to 2015, and who had data available at both baseline and 12 months after surgery were included in this study.

Results

All scores improved significantly from baseline to the 1-year follow-up. BI had moderate to strong correlation with DEMMI, 2MWT, and TUG (r-value: 0.490–0.843), and mild to moderate correlation with EQ-VAS (r-value: 0.278–0.323). All outcome measurements had high effect estimates. The minimal clinically important difference (MCID) of BI at 12 months was 9.8 points.

Conclusion

Since BI was shown to have good validity (moderate to strong correlation with DEMMI and performance-based tests, and mild to moderate correlation with EQ-VAS), BI can be used to accurately assess functional recovery in patients who undergo hemiarthroplasty after femoral neck fracture.
