Summary
A new observational gait scale for lower extremity amputees demonstrates excellent content validity. This tool helps assess altered gait patterns, with future studies planned for reliability and construct validity.
Area of Science:
- Biomechanics
- Rehabilitation Medicine
- Prosthetics and Orthotics
Background:
- Gait patterns are significantly altered in individuals with lower extremity amputations.
- Accurate assessment of gait requires observational tools with strong content validity.
Purpose of the Study:
- To develop a novel observational gait scale specifically for individuals with lower extremity amputations.
- To rigorously evaluate the content validity of the newly designed gait scale.
Main Methods:
- An expert committee was convened to develop and refine the observational gait scale.
- Content validity was assessed using the content validity index (CVI) for individual items and the overall scale.
Main Results:
- The scale comprises 25 items across two sections, with a maximum score of 35 points.
- An overall content validity index (CVI) of 0.90 was achieved.
- The majority of individual items demonstrated high validity, with indices exceeding 0.78.
Conclusions:
- The developed Observational Gait Scale for Lower Extremity Amputation exhibits excellent content validity.
- Further research is recommended to establish the scale's reliability and construct validity.
