semantics - strapping a machine onto you whilst doing an exercise, to remove tension, well, still therapy.
Doing some scapular pulls to strengthen a weak rhomboids = therapy
Don’t get me wrong, I like, i agree, i also do. Though i only have a TENS - which i don’t use that much.
Agree, look at the whole person.
What i feel needs to be expanded upon though, is
One - At some point, you must be doing some form of Hands on therapy, otherwise, HOW do you tell if what you have done, has loosened up the muscle / s enough that you have been targeting? What is your parameter of success?
Two - Due to compensation - Muscles not relieved from tension, will tend to remain under tension, even if the cause is removed.
I used to believe that remove the cause, then the other issues will take care of themselfs. However, Over time, more skill, more practice ect, i have found, even though the Issue goes away - lets use an example,
Hip flexors creating a sore lower back.
You remove and lengthen the hip flexors, the sore lower back goes away.
However, The back and other surrounding muscles have been in a compensation pattern for some time, and even though your range is better, if not Good - there is still tightness in the lower back muscles, still tightness in surrounding hip muscles, like abductors, adductors, hammie ect - It might be too small a tightness to really notice, but it’s still there.
So, you don’t worry about them, and, like the guy on that YouTube video says about ankle sprains - up to 6 months later, other issues come about due to compensation patterns.
I believe, you need to uncover all The layers, remove all the compensation issues.
check, then double check.
Like they say in trade school, Measure twice, Cut once.
The issues are
1 - Fix the hip flexors, bang for buck, biggest improvement for results seen.
2 - Fix the other issues - less visible improvement for Funds outlayed.
3 - Funds available from person willing to pay for what appears like a lot of therapy (if indeed you are removing all compensation issues, seen or otherwise)
Other issues
Cost - ARP = $$ - i could not find a cost, but for accessory’s, you are charged what seems like Hundreds. Could only imagine thousands for the device? I imagine, from what is seen - you need a 2nd person to help control. So, only one person at a time? Like using a TENS
I would still like to get my hands on one though 
Cost for Foam rolling and stretching - less than a Hundred dollars. Can be done anywhere. If you’re training a team of people, it’s easy to teach so they all can do it at their own pace. However, people are also inherently LAZY - and it can HURT - the ARPwave should be a great alternative.
Plus you could charge MORE for use of the ARPwave?
Pakewi - what would be interesting - is to test the ARPwave treatment by using a Foamroller AFTER treatment. If tension is Indeed fully removed, You will know. If you know how to use a Foamroller that is…
I have used many treatment modes -
1 - i would like to get my acupuncture licence.
2 - would like to try and perhaps buy a ARPwave. Never seen one.
3 - Have never tried Cupping - and due to bruising from what i have seen, will never try.
I can’t think of anything else i have not tried. Just so you know
