Introduction:
Gait pattern is altered in persons with lower extremity amputation. To assess gait pattern, it is important to use observational gait scales with a good content validity.
Objectives:
To design an observational gait scale and to analyze its content validity.
Material And Methods:
An expert committee was formed to obtain a version of the scale. The same committee was responsible for evaluating the scale. The content validity index (CVI) was calculated, both for each item and for the global scale.
Results:
The main kinematic and spatiotemporal alterations were selected to design the items. The scale consists of 2sections and 25 items, with a maximum score of 35 points. An overall CVI score of 0.90 was obtained, and an index of validity for most items with values higher than 0.78.
Conclusion:
The Observational gait scale for persons with amputation of the lower extremity showed excellent content validity according to the CVI obtained. Future studies should evaluate its reliability and construct validity.
