Abstract

Objective: To develop the Gait Ability Assessment for hemiplegics (GAA), and to verify its validity and inter-rater reliability.

Methods: We developed the GAA, a new method for the assessment of gait ability. Next, we examined the inter-rater reliability of GAA by assessing gait ability of post-stroke patients by two physical therapists. Then, we verified the validity of GAA by comparing with the existing assessments methods comprising Functional Ambulation Categories (FAC), Functional Independence Measure (FIM)-walk, maximum walking speed, motor subscore of the FIM (FIM-M), and total score of affected-side motor function of the Stroke Impairment Assessment Set (SIAS-L/E).

Results: Regarding the inter-rater reliability of GAA, coefficient was 0.76 and weighted coefficient was 0.96. The correlation coefficients between GAA scores and existing assessment methods were: 0.95 for FAC scores, 0.95 for FIM-walk scores, 0.82 for maximum walking speed, 0.89 for FIM-M, and 0.61 for SIAS-L/E, all of which showed a significant correlation (<0.01).

Conclusion: GAA has high inter-rater reliability as well as high validity as a gait ability assessment method, suggesting that it can be applied to research and clinical settings.
