2For over 3000 years Acupuncture has been used to
treat many diseases, as
- infectious diseases
- musculoskeletal diseases
- internal diseases
- metabolic diseases
- hormonal imbalances
- mental and nervous system diseases
3Acupuncture has been practiced for over fifty
years in Western countries, achieving great
success in treating different diseases. More
than 10,500 scientific publications are
available on Medline database, demonstrating
Acupuncture effectiveness and safety.
4 5Acupuncture in pain
Acute and chronic painful pathologies are one of
the more interesting fields of application of
Acupuncture, that often can cure, alone or with
other therapies, many diseases difficultly
treatable only by the conventional resources.
6So many diseases treated suggest a wide variety
of acupuncture effects, as follows
- anti-inflammatory
- analgesic
- decontracting-miorelaxing
- vasoregulatory
- sedative
- neuroendocrine regulatory
7Vasoregolatory-trophic effect
Documented from the thermography and other
fluxmetric methods, it restores the correct blood
flow in the affected area. Painful diseases are
often characterized by local ischaemia or light
inflammation, frequently associated to edema.
This situation favors the accumulation of waste
and the evolution towards fibrosis, with
functional failure.

9The tissue distress
In the affected area we can see limited zones
very painful
capable of causing pain locally and in a distant
area.
These areas correspond to the traditional Ah Shi
acupoints and to the Trigger points (TP)
described from Travell and Simons as ischaemic
zones with larger metabolic needs. Each TP
embodies a warm hyperexcitated area, that can
cause reflex phenomena locally and at some
distance.
10The ischaemic-irritative tissue condition
of TP zones, through the afferent nerves,
can maintain this distress. Reflex nervous
pathways are involved and these
mechanisms can play a role
- reflex constriction of Vasa Nervorum
- nociceptive autonomic feedback
- release of vasoactive peptides (SP, CGRP) from
afferent C fibres, that increases the stimulation
of nociceptive pathways
11The silent afferences
In 1994 G.D. Schott (Brain, 117397-413) pointed
out the role of autonomic nervous fibres in the
origin of chronic visceral and
musculoskeletal pain. These afferent fibres
represent over 50 of the amielinic C fibres
found in the different tissues (skin, joints,
muscles, viscera).
12 Silent fibres become sensitive and they are
capable of evoking a reaction only after longtime
injuries, as inflammatory and ischaemic
processes. The activation of these afferences can
lead to a central sensitisation, with an
enlargement of receptive fields, causing a more
intense and continuing activity. In this way
chronic pain mantains itself.
13Ischaemic-irritative condition of TP and
oedematose-phlogistic state of affected areas
can both activate C silent fibres and lead to a
chronic condition of the painful disease. Through
the convergence-facilitation and
-projection mechanisms, pain can get the chronic
condition also in the projection zones,which
sometimes are very far from its origin.
14Deactivation of Trigger Points
Mechanic disorganization of TP area can resolve
at the same time local and projected symptoms,
breaking at the root the vicious circle
mantaining the painful disease. The injection of
anestetic drugs inside the TP does not give
better results than dry needle method. Needle
infixion must reach the center of TP and the
stimulation must be strong it is also very
important to obtain the De Qi (needle
sensation) and the propagated sensation of the
needle along the channels.
15Thermal stimulation the moxibustion
Failing visible phlogosis symptoms, the
vasodilating effect is increased from local
application of heat. So, it is possible to
resolve ischaemic pathology forever. The recovery
of a correct blood flow in the affected areas is
the mean condition capable to ensure
- the elimination of waste
- the restoration of tissue nourishment

17Anti-inflammatory effect
The recovery of the tissue nourishment and of the
blood flow, aid the intervention of cellular and
humoral components of the immune system in the
affected areas.Many trials demonstrate the
effect of Acupuncture stimulation on different
components of immune function.
18Antalgic-analgesic effect
- It is possible to get it through two ways
- Electroacupuncture (EA) applied for over 60 min.
due to the release of endogenous opiates by
CNS employed in surgical analgesia the
effect may last some hours - Manual stimulation for a brief time (few seconds)
segmental and suprasegmental reflex mechanisms
are involved, as gate-control system and
descending anti-nociceptive system short

22Acupuncture electroanalgesia (EA)
This method was conceived from Chinese
Acupuncturists in 1958 and later it spread
accross the world, favoured by its good degree of
efficacy. Athough limited to some
operations and thanks to its spectacularity, it
was very appreciated by mass media. Now EA is not
very practised, but it had the historical
role of introducing Acupuncture scientific
research in Western Medicine, pointing out its
capacity to produce endorphins in CNS.

24Manual Acupuncture and EA
Over the millennia Acupunture has been
always executed by hand, to cure the
diseases and not only their painful symptoms. EA,
due to an increased production of endorphines in
CNS, only points out a single effect and it cant
explain by any means the large therapeutic value
of Acupuncture.
25Antalgic effect therapeutic value
Although Acupuncture antalgic effect has
not a true therapeutic role, it can be
useful for treating
musculoskeletal diseases.
Some analgesia degree, even if for a short time,
aids joints mobilization after the treatment and
favours the functional recovery of the affected
areas.
26Decontracting-miorelaxing effect
Muscle contracture depends on segmentary distress
and it represents an attempt to protect the
diseased area. The quick decontracting effect of
Acupuncture involves reflex nervous
mechanisms and affects proprioceptive and
nociceptive pathways. Muscle decontraction and
relaxation permit the
resolution of painful diseases and the
recovery of a suitable tissue
nutrition.
27Sedative effect
Patients suffering from painful and chronic
diseases are often afflicted with anxiety and
depression, caused by the sufference and
the fear thath they will not be cured. The
Acupuncture sedative-antidepressive effect is
very important to improve the patients mental
condition, including the quality of sleep.
28Conclusions
We can say that Acupuncture has a main role in
painful diseases therapy, through its proven
effects. In Western countries Acupuncture
technique is not always the same and often its
quality is not adequate. Acupuncture and
Reflextherapy are in addition often confused,
inside a big group of alternative cares. This
fact favours a big disorder and the diseased
people take all the consequences on themselves.
