Mechanical Determinants of Upper Limbs Oscillation During Gait

"Participants' ground spontaneous speed overground will be tested by means of the 10-meter walking test. Participants will be tested for their foot dominance by means of the Waterloo footedness questionnaire-revised. Participants will walk on a treadmill mounted on force sensors. The test sequence will be the following:~1. Familiarization. Participants will walk on the treadmill with the belt running at increasing velocities up to their spontaneous walking velocity . Speed will be increased of 0.2 m s-1 every 30 s. A brief pause of around 1 minute will follow.~2. Walking. Participants will walk at 0.4 m s-1 and 1.2 m s-1 for at least 30 seconds.~3. Walking with a rigid ankle-foot orthosis. Participants will walk at 0.4 m s-1 and 1.2 m s-1 for at least 30 seconds with an ankle-foot orthosis on the dominant lower limb.~Participants will repeat the last point (n°3) with the ankle-foot orthosis on the non-dominant lower limb. A 3-min pause will follow each section."

"Participants will walk on a treadmill mounted on force sensors. They will walk freely, under tight supervision, but without hanging to any support. The test sequence will be the following:~4\. Familiarization. Participants will walk on the treadmill with the belt running at increasing velocities up to their spontaneous walking velocity . Speed will be increased of 0.1 m s-1 every 30 s. A brief pause of around 1 minute will follow.~5\. Walking. Participants will walk at 0.4 m s-1 for at least 30 seconds. Participants will be informed a few seconds before the changes in belts' velocities with a verbal warning."
