Side-to-side differences in neuromuscular function and associated joint mechanics in the lower limbs and trunk during walking and running one year after acute unilateral Achilles tendon rupture

Abstract

Background: Achilles tendon rupture can result in persistent impairments in neuromuscular function and associated joint mechanics, reflecting altered neural–mechanical coupling despite surgical or nonsurgical treatment and structured rehabilitation. However, knowledge of how these deficits affect lower limb muscle coordination and joint power distribution across the kinematic chain remains limited.
