BACKGROUND: A better understanding of gait kinematics during the 6-min walk test (6MWT) may facilitate the development of rehabilitation strategies for patients with chronic obstructive pulmonary disease (COPD). AIM: To evaluate gait kinematics during the 6MWT in patients with COPD. METHOD: Thirty-six patients with COPD and 19 healthy controls underwent a full-body kinematic analysis during the 6MWT. Data were collected using a system with four infrared cameras to capture the movement of a spherical marker covered with retroreflective tape attached to a helmet worn during the test. RESULTS: The walking distances measured by the assessor and by kinematics analysis were lower in the group of patients (Pâ¯=â¯0.036 and Pâ¯=â¯0.013, respectively). Moreover, the walking distances measured by kinematics analysis were greater than those measured by the assessor for both groups (Pâ¯<â¯0.001). In the kinematics analysis of the complete test, the mean and maximum speeds were higher for the controls than for the patients (Pâ¯=â¯0.007 and Pâ¯=â¯0.044, respectively). In the half-turn analysis, acceleration, speed, and deceleration peaks (maximal absolute values) were lower for the patients than for the controls (Pâ¯=â¯0.002, Pâ¯=â¯0.012 and Pâ¯=â¯0.006, respectively). CONCLUSIONS: Patients with COPD show worse functional capacity due to lower gait speed and acceleration-deceleration peaks after turnings as compared to healthy individuals during the 6MWT. Assessors can accurately predict the 6MWD measured by kinematics, though they underestimate this distance.
