Balance control deficits in individuals with a transtibial amputation with and without visual input.

Individuals with a TTA presented a greater reliance on the intact lower limb, as highlighted by the greater ankle plantarflexion and anteroposterior and ML COP excursions for intact limbs compared with amputated limbs during quiet standing tasks. During EC condition, both groups exhibited greater ML COP excursions compared with EO condition, suggesting less postural stability. These differences may place them at greater risk of falling.
