Validity of the Original and Short Versions of the Dynamic Gait Index in Predicting Falls in Stroke Survivors.
OBJECTIVE
This study aimed to investigate the validity of the original version and short version of the Dynamic Gait Index (DGI-8 and DGI-4) in predicting falls in stroke survivors.


METHODS
This is a retrospective, cross-sectional study.


METHODS
This study collected data for 57 chronic stroke survivors and evaluated the validity of the DGI-8 and DGI-4. To test functional ability, the Sit-to-Stand Test, gait subscale of the Performance-Oriented Mobility Assessment, the 10-m Walk Test, the Fugl-Meyer assessment, and the Trunk Impairment Scale were used.


RESULTS
For the DGI-8, the cutoff value for the prediction of a fall was shown to be 16.5, with an area under the curve (AUC) of 0.78. The cutoff value of the DGI-4 was shown to be 9.5, with an AUC of 0.77.


CONCLUSIONS
The study results show that the DGI-8 and DGI-4 have discrimination in the prediction of fall in stroke survivors.


CONCLUSIONS
DGI-8 and DGI-4 can be useful for predicting falls of stroke patients, allowing better quality of care.
