Determining the safety, feasibility, and effects of anodal transcranial direct current stimulation on corticospinal excitability and quadriceps performance after anterior cruciate ligament reconstruction: a randomized crossover design.

ABSTRACT:

Background

Alterations in corticospinal excitability (CSE) to the quadriceps persist after anterior cruciate ligament reconstruction (ACLR). Centrally targeted interventions, such as transcranial direct current stimulation (tDCS), may be necessary to increase CSE and quadriceps muscle strength. The purpose of this study was to determine (I) the feasibility and safety of a single session of tDCS and (II) the effects of a single session of tDCS on CSE and quadriceps muscle performance in participants after ACLR.

Methods

This was a randomized crossover design of a single session of active vs. sham tDCS, including 20 participants (nine male) 4-6 months post-ACLR. Surgical limb quadriceps performance [peak torque normalized to body mass, rate of torque development from ons
