Keep an eye out for the ones that first evaluate you and show you how you are "locked" by seemingly trying pushing your foot left or right as you lay on your back and then they touch your opposite shoulder with a finger and "unlock" you, now it moves!!! Pay attention to how they move the foot when locked vs unlock - like a pick pocket redirect of attention scam. Easy to notice if you pay attention. Good luck!

Well it depends upon the quality of the therapist, so I'm sure some people have poor results. I am a doctor of Chinese Medicine and acupuncture, so if you have any questions let me know.
