[Purpose]: Using canonical correlation analysis, physical functions related to gait ability were evaluated in subacute stroke patients. [Subjects]: Seventy-two stroke patients in convalescent rehabilitation wards were enrolled. [Methods]: For gait ability, we evaluated gait velocity and gait variability. For physical function, we evaluated both motor and sensory functions of the affected lower limb, muscle tone of the ankle plantar flexor and muscle strength of both lower limbs. Using canonical correlation analysis, physical functions related to gait ability were explored. [Results]: As factors related to gait ability, muscle strength of both lower limbs and motor function of the affected hip were identified by canonical correlation analysis, and muscle strength of the affected lower limb and motor function of the affected hip by multiple regression analysis. [Conclusion]: The muscle strength of the unaffected lower limb was determined to be a factor related to gait ability only in canonical correlation analysis.
