In a recent review of the last 10 years of literature Rosso et al. (2018) found that laser was able to:
- Facilitate neural regeneration
- Accelerate the process of nerve regeneration
- Increase the number of myelinated fibres
- Improve lamellar organization of myelin sheath
- Improve electrophysiological function
- Improve immunoreactivity
- Decrease inflammation and pain
- Release growth factors
- Increase vascular network and collagen
- Assist muscular reinnervation
They concluded that
“laser has beneficial effects on the recovery of nerve lesions, especially when related to a faster regeneration and functional improvement, despite the variety of parameters.”
