The Effect of Four Weeks of Low-Level Laser Radiation (660 nm) on Movement Recovery and Fibroblasts Invasion
Message:
Abstract:
Background

Despite the fact that many researches have been done in regards to spinal cord injury (SCI), it remains an undissolved problem that has an effect on the individual’s life and society. It could be due to complicated events that occur after SCI. Inflammation is an important initiator for after SCI events and low-level laser (LLL), which is known as an anti-inflammatory agent.

Objectives

The aim of this study is the evaluation effects of LLL on the fibroblast invasion, axon number, and functional recovery after SCI.

Methods

Twenty-four adult male Wistar rats were randomly divided into three groups as control, SCI, SCI + laser. Thirty minutes after SCI that was induced by aneurysm clip LLL irritated for 45 seconds daily and continued for four weeks. Functional recovery by BBB score, fibroblast invasion by H&E, and Axons number by Bielschowsky silver staining was assessed.

Results

The data indicated LLL therapy improved BBB score, increased axons number, and decreased fibroblasts invasion around cavity comparing to SCI animals (P < 0.001).

Conclusions

Our result showed that the initiation LLL therapy, in a short time after SCI, could be effective in the reduction of SCI side effects and improved functional recovery
