Description of the Muscle

Origin: Lateral epicondyle of humerus,annular and collateral ligaments ofradius, fascia of lower arm.

Insertion: Dorsal aponeurosis; proximalto the middle finger joints, the aponeuro-sis divides into the ulnar and radial ten-dinous portions that reunite distally tothe joint in an aponeurosis and insert atthe base of the terminal phalanges.

Innervation: Deep branch of radial nerve(C6 to C8).

Action: Extends finger joints, extendswrist, and supports ulnar abduction.

Trigger Points of the Extensor Muscle ofFingers

Preliminary Remarks

Trigger points are found here predomi-nantly in the muscle bellies of the exten-sor muscles of the ring and middle fin-gers. Activation of trigger points usuallytakes place through chronic strain. As-sociated trigger points are often also pre-sent in the finger muscles and the exten-sor muscle of wrist.

Examination of Trigger Points

Typical local twitch responses can betriggered in the middle of the musclebelly in the region of the trigger points.

Therapy of Trigger Points

Targeted intramuscular stimulation withsubsequent passive stretching of themuscle is effective within a short time.Conventional needling and therapeuticlocal anesthesia may also be considered.

258

Description of the Muscle

Origin: Humeral head: medial epicon-dyle of humerus; ulnar head: coronoidprocess of ulna.

Insertion: Lateral surface of radius andpronator tuberosity.

Innervation: Median nerve (C6 and C7).

Action: Pronates the forearm and con-tributes to flexion of the elbow joint.

Trigger Points of the Pronator TeresMuscle

Preliminary Remarks

Trigger points are usually found in theproximal part of the muscle belly. Theiractivation is caused by repetitive prona-tion of the forearm, either through exces-sive workload or through chronic stressfrom sports (e. g., occasional tennis playerwith poor serving technique).The median nerve passes underneath thepronator teres muscle, and sometimes itruns through the muscle. Compression ofthe nerve may lead to a characteristic en-trapment neuropathy that may finally re-semble carpal tunnel syndrome.

Examination of Trigger Points

The muscle is easy to examine by deeppalpation in the cubital fossa. Palpationtriggers the characteristic radiation ofpain.

Therapy of Trigger Points

There is a risk of damaging the mediannerve. Before dry-needling or injectingthe trigger points, the course of the me-dian nerve must be accurately identified.Manual treatment by acupressure isanother option.

Description of the Muscle

Origin: Humero-ulnar head: medial epi-condyle of humerus and coronoid processof ulna.Radial head: anterior surface of radius.

Insertion: Four tendons insert on thelateral bony ridges of the middle pha-langes of fingers II to V.

Innervation: Median nerve (C7 to T1).

Action: Flexes the metacarpophalangealjoints II to V and the proximal inter-phalangeal joints II to V.

Miscellaneous: The tendons of the deepflexor muscle of the fingers pass betweenthe parts of the tendon insertion on theend phalanges.

Trigger Points of the Superficial FlexorMuscle of the Fingers

Preliminary Remarks

The flexors of the fingers, like the tensorsof the fingers, are superficial muscles. Toavoid damage to the nerves, deep nee-dling should never be performed. Triggerpoint activation is caused by chronicstrain due to manual work. In particular,monotonous grasping movements acti-vate these trigger points.

Examination of Trigger Points

It requires only slight pressure to palpatethe trigger points in the middle of themuscle belly. This is done by gently pal-pating through the ulnar and radial flexormuscles of the wrist as well as the palmarmuscle. Accurate identification is con-firmed by increased sensation of painwhen palpating the trigger points whilesimultaneously checking muscle func-tion.

261

Therapy of Trigger Points

Damage to the ramifications of the me-dian nerve and to the ulnar artery andvein should be avoided by taking greatcare during dry-needling or injection.The trigger points are easy to inactivate.Subsequent stretching of the flexors bydorsal extension of the fingers is essentialfor preventing relapses, and patientsshould be advised to do this on their own.

Trigger Points and Areas of PainProjection

In the radial portion of the flexor muscles,the pain radiates into the palmar side ofthe middle finger; in the ulnar portion itradiates into the ring finger or little fin-ger, sometimes with further projectioninto the palm.

12th Rib

Description of the Muscle

Origin: Inferior borders and outer sur-faces of the 5th to 12th ribs.

Insertion: Pubic tubercle, pubic crest,outer margin of iliac crest, inguinal liga-ment, and linea alba.

Innervation: Intercostal nerves (T5 toT11), subcostal nerve (T12), iliohypogas-tric nerve (T12 to L1), and ilioinguinalnerve (L1).

Action: Unilateral contraction rotates thethorax against the pelvis to the con-tralateral side. Bilateral contraction flexesthe vertebral column. Furthermore, itacts as auxiliary muscle for abdominalcompression and forced expiration.

Trigger Points of the External ObliqueMuscle of the Abdomen

Preliminary Remarks

Trigger points frequently develop in con-nection with an acute abdomen (board-like abdomen). Trigger points are also ob-served with diseases of the inner organs,such as dysmenorrhea, diarrhea, spasmof the urinary bladder, and testicularpain. They may occur primarily and thencause secondary abdominal symptoms.More often, however, it is the other wayaround: the presence of visceral afferentstimuli leads to trigger point formation inthe abdominal muscles. Acute lumbago isalso frequently associated with triggerpoints in the oblique abdominal muscles.

Examination of Trigger Points

With the patient sitting, taut bands andtrigger points in this muscle are provokedby rotating movements.

Therapy of Trigger Points

Dry-needling is possible without anyproblem, and trigger point infiltration isalso an option. Injection or acupunctureof the trigger points is performed withthe patient in a supine position. Punctureof the peritoneum must be avoided.However, damage to the inner organsrarely occurs.

Trigger Points and Areas of PainProjection

� External Oblique Muscle of Abdomen,Trigger Point 1

It lies on the anterior border of the costalarch toward the epigastrium. The charac-teristic radiation of pain into the epi-gastrium mimics symptoms of anginapectoris or epigastric complaints.

� External Oblique Muscle of Abdomen,Trigger Point 2

It lies near the muscle insertion on theiliac crest. From here the radiation of painreaches into the inguinal region andtoward the labia or testes. Prolongedstanding causes additional radiation ofpain into the entire abdominal region,which makes it difficult to locate the pri-mary cause.

Description of the Muscle

Origin: Iliac fossa to terminal line of pel-vis, anterior inferior iliac spine, andlacuna of muscles to anterior surface ofthe hip joint capsule.

Insertion: Lesser trochanter of femur

Innervation: Femoral nerve (T12 toL3/L4).

Action: Together with the greater psoasmuscle it forms the strongest flexormuscle of the hip joint (iliopsoas muscle).With the pelvic and lumbar regions fixed,it flexes the thigh. With the femur immo-bilized, it rotates the ipsilateral pelvislaterally.

Trigger Points of the Iliac Muscle

Preliminary Remarks

Muscle shortenings are very commonwith coxarthrosis. The muscle has ageneral tendency to contract and developtrigger points. This tendency is often pro-moted by visceral afferent stimuli occur-ring in response to irritation of the cecumbordering directly on the fascia of theiliac muscle. The trigger points frequentlyappear in association with trigger pointsof other muscles (e. g., quadratus lum-borum, rectus abdominis, and rectusfemoris muscles; tensor muscle of fascialata). Treatment of these secondary trig-ger points is therefore recommended.

Examination of Trigger Points

With the relaxed patient in supine posi-tion, the muscle is directly palpated be-tween the cecum and the inside of theiliac bone. However, adhesions in the re-gion often make this difficult. In this case,manual mobilization of the cecum is usu-ally necessary. One trigger point is foundin the more anterior part of the muscle.Another trigger point is found at the levelof the hip joint.

Therapy of Trigger Points

Acupuncture of the trigger points in theiliac muscle may be attempted if thececum can be moved far enough in me-dial direction. It is important to treat thecause of the visceral lesion as well. Re-lapses are avoided by physiotherapeuticstretching techniques involving exten-sion of the ipsilateral hip joint with maxi-mum flexion of the contralateral hip jointat the same time, and stretching of therectus femoris muscle, which is usuallyalso contracted.

270

Description of the Muscle

Origin: Lateral surfaces of vertebrae T12to L4, and intervertebral disks and costalprocesses of the lumbar vertebrae.

Insertion: Lesser trochanter of femur.

Innervation: Femoral nerve (T12 toL3/L4).

Action: Together with the iliac muscle, itforms the strongest flexor muscle of thehip joint (iliopsoas muscle). With thefemur fixed, it flexes the lumbar spine,posteriorly rotates the ipsilateral half ofpelvis, and laterally flexes the lumbarspine.

Miscellaneous: Between the two por-tions of the psoas muscle lies the lumbarplexus.

Trigger Points of the Psoas Muscle

Preliminary Remarks

The psoas muscle is subdivided into thesmaller psoas muscle and the greaterpsoas muscle. Trigger points arefrequently found in the region of thegreater psoas muscle. They are associatedwith repetitive strain injuries and poorposture of the lumbar spine, and alsowith coxarthrosis. Here, too, there may bevisceral afferent stimuli; they originatefrom the kidney directly overlying thepsoas muscle or from the sigmoid colontraversing on the left. An anterior iliac le-sion is therefore frequently found on theright (anterior rotation of the pelvic half),or a posterior iliac lesion is found on theleft (posterior rotation of the pelvic half).This results in a functional difference inleg length caused by shortening of theleft leg, or lengthening of the right leg,due to distal displacement (on the right)or proximal displacement (on the left) ofthe rotational center of the hip joint. It istherefore recommended to treat not onlythe trigger points but definitely also the

causes of the underlying distortion of thepelvis.

Examination of Trigger Points

The greater psoas muscle can only be ex-amined in a relaxed patient and by usingdeep palpation. It is often very sensitiveto pressure. Jump signs are absent.

Therapy of Trigger Points

Trigger points in the region of the psoasmuscle are usually not accessible to dry-needling or injection, and if so, then onlywith difficulty. Other stretching methodsare therefore recommended, such as my-ofascial release.

Important Acupuncture Points and TheirLocalizations

Because of the relatively protected deepposition of the psoas muscle it is difficultto access via acupuncture.

Description of the Muscle

Origin: Dorsal fibers: iliac crest and ili-olumbar ligament;ventral parts: costal processes of verte-brae L2 to L5.

Insertion: Dorsal part: 12th rib andcostal processes of vertebrae L1 to L3;ventral part: 12th rib.

Innervation: Subcostal nerve and lumbarplexus (T12 to L3).

Action: Flexes the trunk laterally, stabi-lizes the 12th rib during respiration(fixed point for the diaphragm).

Trigger Points of the QuadratusLumborum Muscle

Preliminary Remarks

There are two trigger points in both thedeep and superficial portions of themuscle. Disorders of the sacroiliac jointfrequently present clinically. Activationof trigger points results from acute strain,also in connection with accidents, andbecomes chronic in functional scoliosis(as a result of unequal lengths of the legs)or in primary scoliosis. Associated triggerpoints appear in the region of abdominalmuscles, in the contralateral quadratuslumborum muscle, in the ipsilateral iliop-soas muscle and iliocostal muscle, andoccasionally also in the latissimus dorsimuscle and internal oblique muscle ofabdomen. Additional trigger points arefound in the gluteal region, especially incase of symptoms of nerve root stimula-tion related to nerve roots L5 and S1.

Examination of Trigger Points

First of all, the following orthopediccauses should be clarified: functional orstructural scoliosis, scoliotic pelvis, ob-lique position of pelvis, and displacementof pelvis. Palpation of trigger points isperformed while the patient is lying re-laxed on his/her side. Local twitch re-sponses are rarely observed; usuallythere is distinct hardening of the muscle.

Therapy of Trigger Points

Direct needling is only possible withacupuncture needles of at least 60 mm inlength. Therapeutic local anesthesia is apossible alternative. However, dry-nee-dling can usually be successfully per-formed as well; in lateral position, theneedle is aimed in the direction of thetransverse processes. As follow-up treat-ment, stretching the muscles is carriedout in the dorsal position with the hipjoint flexed approximately 80° usingpostisometric relaxation by adduction ofthe hip joint. This also stretches the en-tire gluteal region.

Insertion: Gluteal tuberosity of thefemur, iliotibial tract of the fascia lata,lateral intermuscular septum.

Innervation: inferior gluteal nerve (L4 toS1).

Action: Extends the thigh in the hip joint;upper fibers: abduction,lower fibers: adduction, rotate the thighlaterally.

Trigger Points of the Gluteus MaximusMuscle

Preliminary Remarks

The muscle has three trigger points. Trig-ger points in this region often appear incombination with those of the gluteusminimus muscle and the sciaticocruralmuscle. Trigger points of the deep dorsalextensor muscles are also found to be as-sociated. Activation often results fromacute events associated with increasedstrain of the gluteus maximus muscle.Such trigger points are thereforefrequently found in athletes.

Examination of Trigger Points

The trigger points lie superficially andcan easily be palpated. Local twitch re-sponses are rarely observed. Especially inthe case of trigger points 1 and 2, directpressure sensibility of the sciatic nerve inthe sense of Valleix’s points should bedifferentiated.

Therapy of Trigger Points

Inactivation of trigger points is achievedwithout any problem by acupuncture,dry-needling, and therapeutic local anes-thesia. Targeted stretching exercisesusing postisometric relaxation completethe treatment.

Description of the Muscle

Origin: Ala of the ilium between theanterior and posterior gluteal lines.

Insertion: Greater trochanter of femur.

Innervation: Superior gluteal nerve (L4to S1).

Action: Abducts the leg in the hip joint.Stabilizes the pelvis on the side of thesupporting leg, contributes to medial ro-tation of the unsupporting leg.

Trigger Points of the Gluteus MediusMuscle

Trigger points are found along the entiremuscle. They develop especially becauseof strain caused by sports or work, butalso after accidents. Dysfunction of thesacroiliac joint is frequently observed.

Examination of Trigger Points

When the hip joint is flexed by 90° andadducted, direct palpation usually pro-vokes the trigger points. The same posi-tion is used for stretching the shortenedmuscle groups during follow-up treat-ment.Targeted intramuscular stimulation withsubsequent passive follow-up treatmentby stretching the muscle is very effectivehere. Manual therapy, including adjust-ment of the affected sacroiliac joint,should be performed concurrently. Alter-natively, conventional needling or ther-apeutic local anesthesia may be used.

284

Description of the Muscle

Origin: Ala of the ilium between theanterior and posterior lines.

Insertion: Greater trochanter of femur.

Innervation: Superior gluteal nerve (L4to S1).

Action: When fully contracted, themuscle abducts the thigh. With only theanterior portion of the muscle con-tracted, it rotates the unsupporting legmedially; with only the posterior portioncontracted, it rotates the unsupportingleg laterally and extends it slightly. Con-traction on the side of the supporting legcauses stabilization of the pelvis.

Trigger Points of the Gluteus MinimusMuscle

Preliminary Remarks

These trigger points develop quitefrequently in combination with those ofthe gluteus medius. The causes are simi-lar.

Examination of Trigger Points

The gluteus minimus muscle can only bepalpated when the gluteus mediusmuscle is relaxed; the origin of the glu-teus medius is further proximal and su-perficial. With the patient in the lateralposition, palpation is performed with thehip joint flexed by 90° and abducted.

Therapy of Trigger Points

As with the gluteus medius muscle, directmethods such as intramuscular stimula-tion by dry-needling are very effective,when followed by passive stretching withthe hip joint flexed and abducted by 90°.Therapeutic local anesthesia or conven-tional needling are also an option. Patientsshould be advised to do the stretching ofthe muscle on their own.

Description of the Muscle

Origin: Anterior surface of the sacrum.

Insertion: Tip of greater trochanter offemur.

Innervation: Sacral plexus (L5 to S2).

Action: Abducts the thigh and rotates itlaterally.

Miscellaneous: In case of early divisionof the sciatic nerve, the common fibularnerve passes across the piriformis muscleand can be constricted here (piriformissyndrome).

Trigger Points of the Piriformis Muscle

Preliminary Remarks

The two trigger points of the piriformismuscle are often associated with chronicpain in the region of the loin, pelvis, andhip. They are activated by chronic dis-orders of the lumbosacral transition butonly rarely as a reaction to acute strain. Incases where the muscle is shortened, en-trapment of the sciatic nerve (especiallyof the peroneal portion) takes place in ap-proximately 10 % of cases due to the aber-rant course of the muscle; this should beconsidered in the differential diagnosis.Active associated trigger points of the in-ferior and superior gemellus muscles andof the obturator internus muscle appearregularly, as do those of the gluteus me-dius and gluteus maximus muscles.

Examination of Trigger Points

Activation of trigger points is achieved byadducting the hip joint when flexed at90° and simultaneously counter-rotatingthe remaining part of the spinal column.With the patient lying on his/herstomach, the piriformis muscle can begrasped by careful deep palpation be-tween dorsal trochanter and sacrum.

Therapy of Trigger Points

Inactivation is possible by conventionalacupuncture and dry-needling, and alsoby therapeutic local anesthesia. Passivestretching supported by postisometric re-laxation decisively contributes to thesuccess of treatment.
