Tendons and Ligaments
There have been many studies investigating laser use and collagen production.
Rocha et al. (2016) showed significant increases in both type I and type II fibers compared to controls when using 904 nm laser treatment. Whilst Ma et al. (2018) showed increases using both 635 nm and 830 nm.
The main effects of the laser were:
- Fibroblast proliferation
- Increased concentration of thiobarbituric acid reactive substances (TBARS)
- Increase in catalase activity
- Decreased nitrite concentration
Here are before and after pictures from Ma et al. (2018)

As can be seen the increase is dramatic
