LLLT nerve regeneration summary by Shimon Rochkind

Shimon Rochkind is an eminent Israeli neurosurgeon and he is THE pioneer in LLLT nerve regeneration.

He is a specialist in Neurosurgery & Microsurgery, Director of the Division of Peripheral Nerve Reconstruction, Senior Neurosurgeon in the Department of Neurosurgery, Tel-Aviv University, Senior Scientist, Neural & Vascular Institute (N.V.R. labs) and Senior Editor of Photomedicine and Laser Surgery with a formidable international reputation.

Over the past 30 years he has been evaluating the use of phototherapy for intra-operative and post-operative treatment of peripheral nerve injuries. He is also the most delightful, gentle, hard working and committed man you could ever wish to meet.

A prolific author, this latest paper is a digest of his 30 years research

Object This review summarizes the continuous study of low-power laser radiation treatment of a severely injured peripheral nerve. Laser phototherapy was applied as a supportive factor for accelerating and enhancing axonal growth and regeneration after injury or a reconstructive peripheral nerve procedure. In nerve cell cultures, laser phototherapy was used to stimulate activation of nerve cells. Methods Low-power laser radiation was used for treatment of peripheral nerve injury using a rat sciatic nerve model after crush injury, neurorrhaphy, or neurotube reconstruction. Nerve cell growth and axonal sprouting were investigated using laser phototherapy on embryonic rat brain cultures. The outcome in animal studies facilitated a clinical double-blind, placebo-controlled, randomized study that measured the effectiveness of 780-nm laser phototherapy on patients suffering from incomplete peripheral nerve injuries for 6 months to several years. Results Animal studies showed that laser phototherapy has an immediate protective effect, maintains functional activity of the injured nerve, decreases scar tissue formation at the injury site, decreases degeneration in corresponding motor neurons of the spinal cord, and significantly increases axonal growth and myelinization. In cell cultures, laser irradiation accelerates migration, nerve cell growth, and fiber sprouting. A pilot clinical double-blind, placebocontrolled, randomized study showed that in patients with incomplete long-term peripheral nerve injury, 780-nm laser radiation can progressively improve peripheral nerve function, which leads to significant functional recovery. Conclusions Using 780-nm laser phototherapy accelerates and enhances axonal growth and regeneration after injury or a reconstructive peripheral nerve procedure. Laser activation of nerve cells, their growth, and axonal sprouting can be considered as potential treatment of neuronal injury. Animal and clinical studies show the promoting action of phototherapy on peripheral nerve regeneration, making it possible to suggest that the time for broader clinical trials has arrived.
