Assessment

Primary outcomes

Oxygen consumption (VO2). VO2 will be measured using a respiratory gas analyzer during 6-minute treadmill walking under each condition, and the mean value from 3 to 6 minutes after the start of walking will be evaluated.

Key secondary outcomes

Carbon dioxide output (VCO2), heart rate (HR), respiratory rate (RR), minute ventilation (VE), tidal volume (TV), modified Borg Scale, center of mass, walking speed, step length, stride length, lateral circumduction of the lower limb during the swing phase of walking, pelvic lateral tilt in the frontal plane, and excessive vertical elevation of the trunk and pelvis will be evaluated. Respiratory gas-related variables will be measured during 6-minute treadmill walking under each condition, and the mean values from 3 to 6 minutes after the start of walking will be evaluated.

Interventions/Control_1

Walking without a knee-ankle-foot orthosis (KAFO) or shoe lift. For respiratory gas analysis, participants walk on a treadmill for 6 minutes at the predetermined comfortable walking speed. For three-dimensional motion analysis, participants walk along an approximately 6-m walkway at a comfortable walking speed.

Interventions/Control_2

Walking with a knee-ankle-foot orthosis (KAFO) and without a shoe lift on the contralateral side (0-cm condition). For respiratory gas analysis, participants walk on a treadmill for 6 minutes at the predetermined comfortable walking speed. For three-dimensional motion analysis, participants walk along an approximately 6-m walkway at a comfortable walking speed.

Interventions/Control_3

Walking with a knee-ankle-foot orthosis (KAFO) and a 1.0-cm shoe lift on the contralateral side. For respiratory gas analysis, participants walk on a treadmill for 6 minutes at the predetermined comfortable walking speed. For three-dimensional motion analysis, participants walk along an approximately 6-m walkway at a comfortable walking speed.

Interventions/Control_4

Walking with a knee-ankle-foot orthosis (KAFO) and a 2.0-cm shoe lift on the contralateral side. For respiratory gas analysis, participants walk on a treadmill for 6 minutes at the predetermined comfortable walking speed. For three-dimensional motion analysis, participants walk along an approximately 6-m walkway at a comfortable walking speed.

4.Individuals with apparent lower-limb deformity or a leg length discrepancy of 1.0 cm or greater
5.Individuals with wounds, skin disorders, inflammation, or pain at the sites of contact with the knee-ankle-foot orthosis, for whom orthosis use may worsen symptoms
