Knee and ankle joint moments and muscle activation during stair ascent and descent in young adults with flexible pes planus: A comparison with normal foot posture.

This study compared knee and ankle joint moments, muscle activation, and co-contraction between young adults with flexible pes planus and normal foot posture. Forty young adults (20 per group) performed barefoot stair ascent and descent. Three-dimensional motion analysis, ground reaction force, and surface electromyogr...

Effects of Unilateral Leg Training Using Elastic and Inelastic Barbells on Dynamic Balance and Muscle Activation: A Randomized Controlled Trial

Background: Elastic barbells generate continuous, unpredictable perturbations through elastic deformation of the bar, delivering a top-down instability stimulus that transfers from the upper to the lower limbs. Whether repeated exposure produces training-related changes in muscle activation, and whether any postural co...
