A 2011 [[systematic review]] of 43 studies of acupressure's effectiveness at treating symptoms found that the nature of these 43 studies "indicated a significant likelihood of bias."<ref name="Lee"/> Thirty-five of the 43 studies had concluded that acupressure was effective at treating certain symptoms. The authors of this systematic review concluded that this "review of clinical trials from the past decade did not provide rigorous support for the efficacy of acupressure for symptom management. Well-designed, randomized controlled studies are needed to determine the utility and efficacy of acupressure to manage a variety of symptoms in a number of patient populations."<ref name="Lee"/>

A 2011 Cochrane review of four trials using acupuncture and nine studies using acupressure to control pain in childbirth concluded that "acupuncture or acupressure may help relieve pain during labour, but more research is needed".<ref>{{Cite journal |last1=Smith |first1=Caroline A. |last2=Collins |first2=Carmel T. |last3=Levett |first3=Kate M. |last4=Armour |first4=Mike |last5=Dahlen |first5=Hannah G. |author-link5=Hannah Dahlen |last6=Tan |first6=Aidan L. |last7=Mesgarpour |first7=Bita |date=7 February 2020 |title=Acupuncture or acupressure for pain management during labour |journal=The Cochrane Database of Systematic Reviews |volume=2 |issue=2 |pages=CD009232 |doi=10.1002/14651858.CD009232.pub2 |issn=1469-493X |pmc=7007200 |pmid=32032444}}</ref> Another [[Cochrane Collaboration]] review found that massage provided some long-term benefit for [[low back pain]], and stated: "It seems that acupressure or pressure point massage techniques provide more relief than classic (Swedish) massage, although more research is needed to confirm this."<ref>{{cite journal | vauthors = Furlan AD, Giraldo M, Baskwill A, Irvin E, Imamura M | title = Massage for low-back pain | journal = The Cochrane Database of Systematic Reviews | issue = 9 | pages = CD001929 | date = September 2015 | volume = 2015 | pmid = 26329399 | doi = 10.1002/14651858.CD001929.pub3 | pmc = 8734598 }}</ref>

EBM reviewer [[Bandolier (journal)|Bandolier]] said that P6 in two studies showed 52% of patients with control having a success, compared with 75% with P6.<ref>{{Cite web|url=http://www.medicine.ox.ac.uk/bandolier/band59/b59-4.html|title=Nausea and vomiting in early pregnancy |date=1999 |archive-url=https://archive.today/20121223133618/http://www.medicine.ox.ac.uk/bandolier/band59/b59-4.html|archive-date=2012-12-23|url-status=dead }}</ref>

[[Quackwatch]] includes acupressure in a list of methods which have no "rational place" as massage therapy and states that practitioners "may also use irrational diagnostic methods to reach diagnoses that do not correspond to scientific concepts of health and disease."<ref name=Quackwatch>{{cite web|url=http://www.quackwatch.com/01QuackeryRelatedTopics/massage.html|title=Massage Therapy: Riddled with Quackery| first = Stephen | last = Barrett | name-list-style = vanc |publisher=Quackwatch|date=March 9, 2006|access-date=3 June 2013}}</ref>

Clinical use of acupressure frequently relies on the conceptual framework of [[traditional Chinese medicine]]. There is no physically verifiable [[anatomical]] or [[histological]] basis for the existence of [[acupuncture point]]s or [[meridian (Chinese medicine)|meridians]].<ref name="Mann_drunkard">{{cite book | vauthors = Mann F | author-link = Felix Mann | quote =  ... acupuncture points are no more real than the black spots that a drunkard sees in front of his eyes. | title = Reinventing Acupuncture: A New Concept of Ancient Medicine | publisher = Butterworth Heinemann | location = London | date = 1996 | page = 14 }} Quoted by {{cite journal | first = Matthew | last = Bauer | name-list-style = vanc | url = http://www.chinesemedicinetimes.com/section.php?xSec=122 | journal = Chinese Medicine Times | archive-url=https://web.archive.org/web/20090122104312/http://www.chinesemedicinetimes.com/section.php?xSec=122 | archive-date=2009-01-22 | url-status = dead | volume = 1 | issue = 4 | date = August 2006 | title = The Final Days of Traditional Beliefs? - Part One }}</ref> Proponents reply that TCM is a [[prescientific system]] that continues to have practical relevance.
