Definition in Traditional
Chinese Medicine (TCM)
• Sciatica Symptoms is called “BiZheng 痹症” in
•
Traditional Chinese Medicine (TCM).
The HuangDiNeiJin in 475-221 B.C.(The Yellow
Emperor’s Internal Classic) discussed the
syndrome of pain in the low back and leg.
Definition in Western Medicine
• Sciatica (radiculopathy) is a general term that
•
refers to pain caused by compression or
irritation of one or more nerves exiting the lower
spine that make up the sciatic nerve, and there
are a number of different conditions that can
cause this.
Sciatica is a set of symptoms: low back pain, leg
pain and tingling, numbness or weakness that
travels from the low back through the buttock
and down the leg or foot.

Sciatic Nerve
• The sciatic nerve is a large nerve that
runs down the leg. It is the longest single
nerve in the body.
• The sciatic nerve involves L4, L5 and S13 of the spinal nerves.
• It includes the common peroneal nerve
and the tibial nerve.
• It distributes to the skin of the posterior
surface of the leg and the sole of the foot.

Ⅱ Differential Diagnosis of Sciatica
1. General symptoms:
The term sciatica describes the symptoms
of pain and possibly tingling, numbness or
weakness that travels from the low back
through the buttock and down the leg or
foot.
2. General Examination on the Sciatica
1) Mobility of Lumbar Vertebral Column and hip joint :
① Normal lumbar range of motion
Flexion 90°
Extension 30°
Side bend 20°-30°
Twist 30°
② Normal hip joint range of motion
Flexion 145 °
Extension 20-40°
Abduction 30-45 °
Adduction 20-30 °
Lateral rotation 40-50 °
Medial rotation 30-40 °
2) Pressure Points:
•If the lumbar disc is herniated, its
corresponding vertebra has an obvious
tender spot. When that point is pressed
pain occurs along the sciatic nerve
distribution, shooting down along the
lower limb.
• If the piriformis is pressed sciatic pain
occurs.
•If spots along sciatic and that is pressed
the pain occurs.
3) Lasegue’s test: (Supine) If there is pain in the
lumbar area and lateral leg on performing a straight
leg raise up to 70° or dorsiflexing the foot, the test is
positive.
4) Kernig’s test: (Supine) While bending the hip
joint and knee joint to 90° degrees, then extending
the knee, if pain is induced, the test is positive.
5) Abdominal pressure test: In the supine
position, the patient is asked to push the abdomen out
while holding breath in. If pain occurs at the lower
back or leg, the test is positive.
6) Lindner’s test: The patient’s neck is passively
flexed, gradually bringing the chin to the chest. If
pain occurs at the lower back and leg, the test is
positive.
7) Piriformis test: Patient side lie, sick leg up
and bend 90 °, push down lateral knee of sick leg,
if pain occurs at buttock and leg, the test is positive.

1. Acute Lumbar Injury *
Acute lumbar injury include : lumbar muscle
strains and lumbar sprains.
• A low back muscle strain occurs when the
muscle fibers are abnormally stretched or torn.
• A lumbar sprain occurs when the ligaments, the
tough bands of tissue that hold bones together,
are torn from their attachments.
Diagnosis Points of Acute
Lumbar Injury
1) Indication of injury to the lumbar.
2) The pain is mostly in the lower back.
Sometimes the pain affects the leg, but there is
no shooting pain in sciatic nerve distribution.
3) Pain is aggravated by movement, alleviated by
rest.
4) An obvious tender area is easy to find at low
back.
5) CT or MRI does not show a disc herniation.
2. Lumbar Spinal Stenosis ***
Lumbar spinal stenosis can be caused by:
• Tumors or herniated discs
• Degenerative change (arthritis) made the
spinal canal narrow that occur with aging,
e.g. this is most common reason
Diagnosis points of Lumbar
Spinal Stenosis
1) Lumbar spinal stenosis occurs with aging.
2)
3)
4)
5)
Males are affected slightly more than females.
Lumbar spinal stenosis occurs mainly in the L3
- S1 region.
Lower back pain or leg pain (may have
shooting pain) often occurs when walking or
standing for a periods.
Intermittent claudication.
X-ray, CT or MRI can locate the areas of
narrow of the spinal canal.
Lumbar Spinal Stenosis Figure
3. Piriformis Syndrome***
• The piriformis syndrome is a condition in
which the piriformis muscle presses or
irritates the sciatic nerve, causing pain in
the buttocks and leg, with referred pain
commonly called sciatica.
Diagnosis points of Piriformis
Syndrome
1) History of injury to the buttock.
2) Patients generally complain of pain deep in the
buttock, which is made worse by sitting,
climbing stairs, or performing squats.
3) No low back pain.
4) Piriformis examination will be positive.
5) CT or MRI does not show a herniated disc.
Piriformis Figure
Greater sciatic notch
4. Sciatic Neuritis***
Sciatic pain mainly caused by viral infection,
which damages the sciatic nerve.
This is also called the primary infectious
cause of sciatic pain, and isn’t commonly
seen clinically.
5. Spinal Tumors*
• The cause of pain may be a spinal
tumor — a cancerous or noncancerous
growth that develops within or near the
spinal cord or in the bones of the spine, if
the spinal cord or nerve root is pressed
the low back pain or leg pain occur.
6. Sacroiliac Joint Injury*
• The sacroiliac joint (SI joint) is a firm,
minimally mobile joint that is at the
junction of the spine and the pelvis. The
sacroiliac joint does not move much, but it
is critical to transferring the load of your
upper body to your lower body.

Indication of lumbar injury
Pregnancy or delivery may injure the SI joint
Pain on one side lower back, without leg pain
Faber’s test (“4” character test ) is positive.
Studies X-Rays, MRIs, CAT Scans, Bone Scans
are abnormal.
7. The Third Lumbar Transverse
Process Syndrome**
• The pain spot is at the third lumbar
transverse process, and also affects the
buttocks and lateral thigh. That is caused
by the friction between transverse process
and quadratus lumbolum muscles, which
causes inflammation. The third lumbar
transverse process may be normal in
length, or too long.
Diagnosis points of the third lumbar
transverse process syndrome
1) The pain can be on one or both sides of the third lumbar
region, and may radiate to the posteriolateral part of the
thigh in the severe cases.
2) The patient is unable to sit and stand for long, with pain
aggravated on sitting or standing and alleviated after
rest.
3) Pressure point at L3 transverse process.
4) A longer or normal transverse process of the third
lumbar vertebra is shown in the X-ray or MRI film.

8. Pelvic inflammatory disease*
Pelvic inflammatory disease (PID) is a
general term that refers to infection of the
uterus, fallopian tubes, vagina, bladder etc.
The inflammation can irritate the tissues and
the muscle, causing lower back pain.
Diagnosis points of PID
1)
2)
3)
4)
Lower back, with no history of injury.
Abnormal vaginal discharge.
Antibacterial treatment reduces the pain.
Laboratory examination and ultrasound or CT
exam reveals the problem.
9. Entrapment syndrome of
superior cluneal nerve**
• The medial branch of the superior cluneal
nerve passes over the iliac crest through a
tunnel (Osteofibrous tract ) down to the
buttocks. In that particular area the
superior cluneal nerves are compressed
easily when injured. They innervate the
skin of the upper part of the buttocks and
lateral thigh.
Diagnosis points of entrapment syndrome of
superior cluneal nerve
1) Indication of injury to low back.
2) The pain spot at 1/3 lateral of line, the line
3)
4)
5)
from L4 of spinous process to iliac crest.
It may also occur during pregnancy.
The pain occurs in the buttocks and radiates to
the lateral thigh.
Bending the waist and walking causes pain.
Also, changing posture from sitting to standing
is difficult.

10. Entrapment syndrome of the
lateral femoral cutaneous nerve**
• It is a syndrome of pain in the lateral and anterolateral
•
•
thigh.
The lateral femoral cutaneous nerve passes through and
underneath the lateral aspect of the inguinal ligament,
and above the sartorius finally travels to innervate the
lateral thigh and the mid thigh.
If the nerve is pressed when injured, it causes burning
pain and numbness of the greater trochanter region and
the mid thigh.
Diagnosis points of Entrapment Syndrome of
the lateral femoral cutaneous nerve
1) Sports injuries such as trauma or muscle tears of the

lower abdominal muscles may also result in irritate to
the nerve.
It may also occur during pregnancy or procedures of
give birth.
It may also be caused by injury from surgical
procedures.
There is pain on deep pressure just below the anterior
superior iliac spine and from hip extension.
The pain is at the lateral thigh or anterolateral thigh
and down to the knee and also sometimes in the
inguinal region.

11. Greater trochanteric bursitis**
• Greater trochanteric bursitis is
characterized by inflammation of the bursa
located just superficial to the greater
trochanter of the femur.
• Patients typically complain of lateral hip
pain, although the hip joint itself is not
involved. Pain may radiate down to the
lateral thigh or lateral knee.
Diagnosis points of greater
trochanter bursitis
1) The typical symptom is pain at the greater

trochanteric region.
Pain may radiate down the lateral aspect of the
thigh to the knee. Pain usually does not radiate
all the way into the foot.
Typically, symptoms worsen when the patient
is lying on side of affected bursa (eg, lying in
the lateral decubitus position).
Pain may awaken the patient at night.
Greater trochanter
12. Entrapment Syndrome of
Common Peroneal Nerve***
• The common peroneal nerve courses around the
fibular neck and passes through the fibro-
•
osseous opening (notch) in the superficial head
of the peroneus longus muscle. This opening
can be quite tough and result in the nerve
passing through it at an acute angle.
The common peroneal nerve gives off 2
branches: the superficial peroneal nerve (the
lateral cutaneous nerve of the calf ) and deep
peroneal nerve (the sural communicating branch
nerve )

14 Herniated Lumbar Disc***
Lumbar intervertebral disc injury leads to
• partial damage to or tears of the annulus
fibrosus
• protrusion of the nucleus pulposus
• compression of the spinal nerve roots
• lower back pain, leg pain (including shooting
pain)
• Most commonly seen in individuals aged 25-55
years
• Males are affected slightly more than females
Structure of the Intervertebral Disc
1) Hyaline Cartilage: is the cartilage of the superior and
inferior surfaces of the vertebral body. It also forms the
top and bottom border of nucleus pulpous. It bears the
weight and protects the annulus fibrosus and nucleus
pulpous.
2) Annulus Fibrosus: is a fibrous ring, like a radial tire. It
is elastic, embracing and holding the nucleus pulpous,
not letting it herniate.
3) Nucleus Pulpous: is a kind of gelatinous, flexible,
semifluid material, located in the center of the annulus
fibrosus. Both top and bottom surface are sealed by
hyaline cartilage.

Three patterns differentiated by the condition
of nucleus pulpous herniation
1)Protrusion or bulging: The annulus fibrosus is not torn
but protruding or bulging, compressing the nerve root.
2)Extrusion: The annulus fibrosus is torn, and the nucleus
pulpous herniated to compress the spinal cord or nerve
roots.
3)Sequestration: The annulus pulpous is ruptured, the
fragment of nucleus pulpous has traveled below the
posterior longitudinal ligament and herniated into the spinal
canal, compressing the spinal cord or nerve root.

Diagnosis of Herniated Lumbar Disc
• 1)
Low back pain: The pain is mainly located in the
lower back area; The painful area is deep, and it is
usually dull pain or severe (burning), acute pain.
• 2) Shooting pain in the lower limbs:
Lumbar disc herniation often occurs at the L4-5 or L5S1 level, causing lower back and hip pain radiating
down the thigh on the lateral and posterior sides,
down the lateral side of the lower leg, and to the
medial and or lateral side of the foot, and toes.
Coughing or sneezing can aggravate the pain, causing
shooting pain down the lower limbs.

3) Numbness and tingling:
• Herniation of lumbar discs causes
compression of the spinal nerve roots, and
local inflammation and swelling.
• Resulting nerve compression and lack of blood
circulation causes malnutrition to the nerves.
• The symptoms are tingling, numbness and
muscle atrophy; the worst is foot drop.
4) Abnormal spinal curvature:
After lumbar disc herniation, 64% of patients
have abnormal spinal curvature. The curve of the
vertebral column is the body’s way of protecting
(instinctive protecting) from low back pain and leg
pain. Lateral curvature can relax the nerve root
and relieve pain.

Ⅳ TCM Treatment for Sciatica
TCM treats sciatica with four methods:
• Acupuncture
• TuiNa
• Herbs
• Traction

Balance body energy .
Adjustment hormones.
Relieve pressure (decompression).
Reduce pain.
Increase blood circulation in particular areas.
Activate the acupuncture channels (meridians).
Alleviate muscle spasm, relax muscles.
Repair damaged soft tissue.
Adjust joints.
Modern Research of Acupuncture
and TuiNa
1) Increases content of Beta-endorphin (END) and
Catecholamine (CA) in blood to help reduce pain.
2) Decreases content of 5-hydroxytryptamine (5HT) in the blood to reduce pain.
3) Increase blood circulation.
4) Help immunity function.
5) Relieve the pressure of local body
(decompression).
5-hydroxytryptamine (5-HT) is a monoamine
neurotransmitter synthesized in serotonergic neurons
in the central nervous system (CNS) and
enterochromaffin cells in the gastrointestinal tract of
animals including humans.
Beta-endorphin (END) is an endogenous opioid
peptide neurotransmitter found in the neurons of
both the central and peripheral nervous system.
Catecholamines (CA) are chemical compounds
derived from the amino acid tyrosine, Catecholamines
as hormones are released by the adrenal glands in
situations of stress such as psychological stress or
low blood sugar levels.

Ⅴ Cautions and Contraindications
• At the acute stage, don’t use heavy manipulation (TuiNa)
and traction, but you can do acupuncture and herbs .
• Surgery for herniated lumbar disc, if one of the following
happens:
①If symptoms are very severe, if symptoms occur
repeatedly for years, or if alternative treatment is not
working.
②If there is central herniation, with compression to cauda
equina nerves that causes sphincter dysfunction.
③If there is Nerve root compression with numbness and
foot drop.
Ⅵ Rehabilitation and Prevention
• During recovery from lumbar disc
herniation, focus on muscle exercise of
abdominal and lower back that can
balance the vertebral column and prevent
herniation.
• Avoid carrying heavy things.
• Periodic treatment (acupuncture or TuiNa
or massage ) for lower back.
• Prevent osteoporosis.
