| Popis: | This study determined the differences in 2-Minute Walk Test (2MWT) distances between people with lower limb amputations in clinical and research settings and described variations in test administration in various clinical settings.Retrospective Cross-sectional design.The 2MWT for 290 patients with lower limb amputations were obtained from a medium-sized prosthetic company with locations within the central United States. Data on 12 prosthetists' 2MWT administration decisions were obtained from the results of an administrative questionnaire. Patient 2MWT distances were compared with published distances. Multiple regression was used to examine the impact of test settings on 2MWT outcomes. Descriptive statistics were used to present prosthetists' variations in test administration.Clinical 2MWT distances were significantly less than distances obtained in a research setting. Clinical facilities reported inconsistent path dimensions and potential obstacles in proximity to the test area. Variations in test administration by prosthetists with respect to path length, instructions, turn marker, and overage measurement may contribute to the differences.Prosthetists should be aware that comparisons of patients' 2MWT distance in a clinical environment may differ from published results. Although variations in clinical environments are usually nonmodifiable characteristics of the clinical facility, test administration and scoring could be modified. |
