In this study, crutch and crutch gait for the handicapped in the lower extremity were discussed, and the study was conducted as a part of long-term research that suggests a practical solution for a crutch design. Three axillary crutches were evaluated in the study by a set of design guidelines for crutches delivered from the advanced research. In this comparative study with axillary crutch design variations, 31 healthy subjects were participated and three crutches were evaluated by ten guidelines. The result showed that Mobilegs-ultra and In-motion Pro were significantly greater than KM Crutch. However, no statistically significant difference was found between Mobilegs-ultra and In-motion Pro. While analyzing with guidelines, Mobilegs-ultra and In-motion Pro were significantly greater than KM Crutch for 6-guideline, but no significant difference was found among three crutches for the guidelines related with Lightweight and Economical feasibility and marketability. The result of the study is expected to be used for a solid foundation to evaluate for the reasonableness of the guidelines with comprehensive analysis for crutch gait evaluation in the further study.
