This is a good video on many different brands of red light "wearable" therapy devices.
The speaker is not trying to sell you anything.
However, her talk is just general without science-backed info or links.
She does offer useful information, so it's worth your 30 minutes.
I do believe in PMB for wound-healing and pain relief.
I'm not convinced it works for PD.
If it did... Michael J. Fox would be the first one using it, doncha thunk?
