Comparison of the 6-minute Walking Test in a Corridor and on a Non-motorized Treadmill (TDM6)

Comparison of the 6-minute Walking Test in a Corridor and on a Non-motorized Treadmill, Feasibility Study

Evaluation of the equivalence of 6-minute walking test performed on a non-motorized treadmill to the reference test : a 6-minute walking test on a corridor.

The Six-Minute Walk Test (6-WT) is a standardized test to assess a person's functional ability to walk as far as they can in six minutes. It is widely used in the assessment of functional disability in response to medical intervention in respiratory and cardiac conditions. This test requires a corridor measuring between 20 and 30 metres and does not require any special technical equipment or training. While the test appears simple to set up, factors such as the length or width of the corridor, and external disruptive elements, may affect the results. Indeed, the configuration of the test site plays a role in the test result. For example, the distance traveled in a 6-minute walking test is greater on a continuous circuit than in a lane that requires people to walk back and forth or when others are using the lane (zigzags, slowdowns). In a hospital setting, while it is easy to find a corridor that is long enough, it is not always possible to dedicate it exclusively to walking tests. An alternative would be to perform this test on a non-motorized treadmill to avoid these biases. The main objective of this study is to evaluate the equivalence of a 6-minute walking test performed on a non-motorized treadmill to the reference test in healthy subjects. In addition, a small number of patients will be invited to perform a 6-minute CT scan on a non-motorized treadmill in order to first evaluate the perception and acceptability of this new method in this population (seniors, pathologies). If the results are conclusive, a similar study with patients only will be performed.

Healthy subject will be asked to performed two 6-minutes walking test : one in a corridor and one on the non-motorized treadmill. Oxygen saturation, heart rate and Borg score will be collected before and after each test.

Patients will be asked to to performed a 6-minutes walking test on the non-motorized treadmill and to answer a questionnaire regarding the acceptability and ease of use of the new method.

6-minutes walking test on a corridor : patient will be asked to achieve the longest possible distance without running. He/she will be allowed to take breaks if he/she feels the need to do so.

6-minutes walking test on a treadmill : patient will be asked to achieve the longest possible distance without running on the treadmill. He/she will be allowed to take breaks if he/she feels the need to do so.

To assess the equivalence of walking distances obtained with the 6-minute walk test on a non-motorized treadmill to the baseline (6-WT on a corridor) test in healthy subjects.

Heart rate before and after each test : 6-WT on a corridor and on a non-motorized treadmill in healthy subjects.

Oxygen saturation before and after each test : 6-WT on a corridor and on a non-motorized treadmill in healthy subjects.

Borg scale before and after each test : 6-WT on a corridor and on a non-motorized treadmill in healthy subjects.
