Yes, just as good, just less expensive. All of them are 1 MHz frequency. The 1 MHz energy is absorbed less rapidly and can therefore be more effective at greater depth, making it useful to treat deeper muscular problems like sciatica. The clinical version may or may not have a 3 MHz frequency too, plus 2 or more heads. The difference is the 3MHz ultrasound is absorbed more rapidly and used to treat superficial injuries. For all intent and purposes the 1 MHz frequency is all you need because the injuries most of us deal with are deep muscular injuries.
thanks for this man! great write up. I may just have to take a better look into this for an ongoing problem Ive had for years that no one has yet to be able to help with, includes several Drs telling me its likely too tight of lig/tendons and would have to be snipped. fauk that.
PS: thank you for the "all intent and purposes"!
