Gait and Energy Expenditure in Children With Lower Limb Amputation (MAPEDE)

"SESSION 1:~Physiotherapy assessment: clinical parameters, length of limb segments, range of motion of the lower limbs, muscle strength of each lower limb joint and trunk.~Measurement of energy expenditure:~6-minute walking test with prosthesis, at a constant submaximal speed, with portable gas exchange analyzer to measure oxygen consumption and a connected device to calculate the Physiological Cost Index.~* During test: recording of heart rate at the start, each minute, at the end then 5 minutes after the end, recording of the effort perceived by the child each minute (Borg scale)~* At the end : questionnaire to assess child level of acceptability regarding the measurement of the O2 (Oxygen) consumption~SESSION 2:~Measurement of kinematic parameters by gait analysis: the child will be requested to walk with their prosthesis and shoes at spontaneous speed and at maximal gait speed.~The second measurement of energy expenditure will be conducted using the same procedure as the first."
