Construct validity of the 2-minute walk test for patients with lower limb amputation using prosthesis

ABSTRACT Allied to functional assessment, walking tests have been reported to be reliable and valid for several populations, quantifying an individual’s functional capacity and responding to changes during the rehabilitation process. This study aims to analyze the construct validity of the 2-minute walk test for patients with prosthetic lower limbs undergoing rehabilitation. A total of 51 patients aged over 18 years underwent the 2-minute walk test. These individuals had a clinical diagnosis of lower limb amputation at any level and had undergone rehabilitation at least six months at the time of assessment, which was correlated with the Functional Measure for Amputees (FMA) questionnaires and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) aspects to obtain the Pearson Correlation Coefficient with a significance level of p
