Effects of electrical stimulation on tendon repair

An invasive approach to accelerate tendon healing in vivo with direct current electrical stimulation is presented in this study. Achilles tendons of rabbits have been transected and repaired on both legs. An electrical circuit was designed to provide a 7-mAmp current on the repair site of one leg wh...

Achilles tendons of rabbits have been transected and repaired on both legs. An electrical circuit was designed to provide a 7-mAmp current on the repair site of one leg while the other acts as control.
