Ron Hirschberg DVM veterinarian, interview about LLLT low level laser therapy

Ron Hirschberg - 2013 (Video)
In this 13 minute video Ron Hirschberg, DMV, tells of his personal experience with LLLT, and on to his use of LLLT in his veterinary practice, the video is made by thor, so it could be biased

Veterinarian Ron Hirschberg tells of how he first experienced laser therapy on his own arthritis, and decided to invest in lasers for his practice. Since he started using laser therapy on the pets he works with he has seen many positive results, he explains that gross profits from NSAIDs decreased from 0.71% to 0.3%, and laser profit now makes up 4% of the practice's income. He will treat between 3 and as many as 13 patients with LLLT, 95% of which he says improve noticably faster than those without LLLT.

Django's 1st Low Level Laser Therapy (LLLT)

Django is now 13 months old and has had clicking and obvious pain in his right knee for the last 6 months. After a negative valley fever test & 2 knee x-rays showing no fracture or tumors,and being told by 2 vets, it's possibly a soft tissue (CCL/ACL) injury and that he needed a CT, MRI or arthroscopy to get a more definitive diagnosis. Django's owner decided to try LLLT to alleviate some of his pain.

Django Post MPL Surgery Days 1-2

Django had surgery (medial imbrication, with a lateral release & anti-rotational sutures) on his left knee to correct a grade 2 medial patellar luxation August 20, 2015-. Here he is the day of surgery from check in through 48 hours later getting cold laser therapy.

Home Search Introduction

Welcome to the research tool. This tool is a searchable collection of technical publications, books, videos and other resources about the use of lasers for photobiomodulation. This tool includes almost the entire U.S. library of medicine research papers on LLLT, videos from Youtube associated with therapy lasers and the tables of contents from laser therapy books. This allows users to search for a keyword or condition and see resources about using lasers to treat that condition. All the resources include links to the original source so we are not making any statement about the use of lasers for treating non-FDA cleared application, we are simple summarizing what others have said.  Where every possible, we have included a link to the orginal publication.

Here are some of our favorite queries:

This tool uses a broad match query so:

  • It does not correct spelling and searches only cold laser related subjects so do not use LLLT, cold or laser in the search bar
  • It works better with shorter search terms or even parts of search terms
  • It searches all the available fields so you can enter a body part, author, condition or laser brand.
  • Where ever possible, the detailed section about the resource will link to the sources.
  • This system is only for photobiomodulation or cold laser therapy research (including LLLT, laser acupuncture and high power laser therapy) only. It does NOT include photodynamic laser therapy (where the laser is used to react with a pharmaceutical), hot surgery lasers or cosmetic lasers. It does include some resources on weight loss and smoking cessation.

The results of the search are sorted based on 3 quality factors on a scale of 1 to 10 with 10 being the best score. Originally all the resources were given a 5-5-5 until they could be individually evaluated. These scores are purely opinion and are only used to simplify the rank of the results from more valuable to least valuable. This should not be considered a critique of any work. This system was created to help researchers (including ourselves) find the most usable resources for any cold laser therapy research. The resources are assigned values based on the following 3 factors:

  • Efficacy: The resource (especially research papers) should show a significant improvement in the condition being treated. Resources that show better results are given a higher quality score.
  • Detail: The source must give enough information that the results can be duplicated. If a resource lacks too many details that it cannot be recreated, it is given a lower detail score.
  • Lack of Bias: Many resources are created to try and show that one device is superior to its competition. Many manufacturers have staff that crank out biased papers on a regular basis on the hope that this will make their product look superior. If the author of the resource is paid by a manufacturer of the resource appears to be biased towards one device and not one technology, the resource has much less value.

Over the past few years of working with research, we found that a majority of the published resources are lacking in one of these three ranking factors.
The original goal of this research tool was to tie published resources to the protocols in the library. This connection allows users to trace each protocol back to a list of resources so the protocol can be researched and improved.

General Comments

When many of the first research papers were published, the most power laser available for therapy were less than 100mW and many systems had to be pulsed to keep the laser from burning out too quickly. Today, system are available that will deliver up to 60,000mW of continuous output. Because of these power limitation, many early studies were limited to extremely low dosages by today’s standards. It takes a 50mW system 17 minutes to deliver 50 joules at the surface of the skin. If this was spread over a large area of damage or was treating a deeper problem, the actual dosages were much less than 1J/cm2.  Today, we know that these dosages typically produce very little or no results.
About 80% of the resources in this database are in the near infrared wavelength. There is also some interest in the red wavelength (600 to 660nm) . Other wavelengths like blue, purple, and green have very little scientific research behind them and have not gotten much traction in the core therapy market with the exception of some fringe consumer products.
