This study examines how different ankle supports affect walking efficiency in people with spinal cord injuries using a specific type of walking aid called an isocentric reciprocating gait orthosis (IRGO). The researchers compared walking with IRGOs that either completely restricted ankle movement or allowed some ankle movement (dorsiflexion-assisted AFOs). The study found that allowing some ankle movement led to faster walking speeds, greater endurance, and reduced energy consumption compared to restricting ankle movement.
The use of dorsiflexion-assisted AFOs with IRGOs can improve walking speed and endurance in people with SCI.
Dorsiflexion-assisted AFOs may reduce the energy expenditure required for walking with IRGOs, making it a more sustainable option for individuals with SCI.
The findings suggest that clinicians should consider incorporating dorsiflexion-assisted AFOs into IRGO prescriptions for SCI patients to optimize gait performance and reduce energy cost.
