Laser Therapy- 3b vs class IV.

Laser Therapy- 3b vs class IV.

This week I have had to buy some more safety glasses for my laser therapy. Stupidly I have misplaced them in our house renovation. Boy… will I be extra vigilant in the future because they cost £130 a pair!

Any way, I was on the THOR site and came across something that reminded me why I have a 3B laser not a class IV laser.

There are now more and more class IV lasers being used by vet nurses in the UK. I worry if they have the scientific knowledge to understand how to administer laser appropriately.

Last year I completed some masters level research on using laser for dogs with hip joint dysfunction. I found that laser had a significant effect on pain related behaviour. The literature review was extensive and I really had to get my head around the physics!!! However, the recommended dosage is about 6J per point for pain relief. I administer this in 30 seconds per point with my 1W laser. For inflammation the research shows you need a gentler approach with an LED pulsed laser, which I also administer.

The penetration depth I can achieve with my 1W laser is up to 5cm through clear skin. The research to support this is a bit thin, but there is evidence to support superficial use of laser over acupuncture points has a statistically similar effect to acupuncture (Shen et al. 2008), and a better effect than acupressure (Kannan 2012).

Oreo sadly had an awful accident on 21st January which meant he lost all use of his back legs. We were all heart broken...

And here is Oreo today. We could not be happier with the results. It's a long road but Hannah is brilliant.
