Introduction: Posttraumatic nerve repair and prevention of muscle atrophy represent a major challenge of restorative medicine. Considerable interest exists in the potential therapeutic value of laser phototherapy for restoring or temporary preventing denervated muscle atrophy as well as enhancing regeneration of severely injured peripheral nerve. 

Conclusion: Results of the experimental study on denervated muscles suggests that laser treatment can restore its function to a substantial degree when initiated at the earliest possible post-injury stage. These findings could have direct therapeutic applications for preserving the function of denervated muscle after peripheral nerve injury.
