Hello, Im a forum Newb, but also a Vet Technician. One of the doctors at my practice does acupuncture. I think the whole placebo effect between the owner and patient definitly appies to acupuncture. one important difference between pain meds and acupuncture: pain meds are given at home, acupuncture at the clinic. Many dogs hate coming to the clinic and really stress out ,but they just LOVE getting in the car to go home (No matter what the reason for the visit). Some pets get so excited their tempuratures can shoot up to 103.0F - 104.0F just from being at the vet, surrounded by strange dogs and cats, knowing that something bad is coming. Cats that the owner had to catch and spend 30 minutes trying to shove into the carrier at home will DASH into the same carrier after their appointment is finished. I think many patients are so pumped full of adrenaline by the time they are done with acupuncture (which is a longer than average office visit) that even if they come limping in, they are able to drag their owner back to the car!! Then the owner thinks 'wow that really helped'. Now with pain meds their daily routine doesnt change much, they are at home every day (dogs like being at home), and many owners hide pills in food (Dogs like food). No stressful events to trigger excitement/panic. If a medication works it works, no other factors to influence response. Many clients and co workers comment on how much happier the patients immediatlety after acupuncture (or laser therapy boooo), ie when the dog knows its going home. Thats just my personal theory!
I also see the placebo affect on people i work with. When the acupuncturist first got certified everyone was so excited. She even gave coworkers acupuncture for free! Many of my coworkers had tendonitist or mirgraines, neck pain etc. and from time to time, Id see a doctor with needles sticking out of his neck. or a receptionist answering a phone with needles on her face (for migraine), or our groomer with needles all over her wrist, or another tech will needles all up and down her back (Back Pain). i called them my 'porcupine pals'. but years later, no one is as excited. the tech got back surgery (cyst near spinal cord) but not before wasting a few months with a chiropracter, the groomer gets cortisone injections from time to time, the employees with migraines still take their pills. no more porcupine pals

. its just not new and exciting anymore.
