Big distance = restriction in hip extension Hip Drop Test a. screens for the ability of the lumbar and lumbothroacic region to sidebend away from the side of the hip drop b. pt stands with doc seated behind pt c. doc places fingers on superior and lateral surface of iliac crest with palms facing floor d. pt is told to bend one knee without lifting his/her heel off the floor and allowing the hip to drop downward. e. note the change in levelness of the horizontal plane (Normal hip drop is 20-25 degrees), look for smooth lumbar curve f. Positive = the plane of the iliac crests drops less than 20 degrees and/or the lumbar and thoracolumbar spine does not side bend with a smooth lateral curve; named to the side that is weight bearing (Ex: L leg bends and L crest does not drop: Positive R hip drop : restriction to SB g. Positive test suggests that T-L and/or lumbar spine has difficulty SB toward the weight bearing side. Use the proper nomenclature and shorthand notation for lumbar spine somatic dysfunction. 6 I. II. Remember Fryette’s a. 1st Principle - When sidebending is attempted from neutral (anatomical) position, rotation of vertebral bodies follows to the opposite direction. b. 2nd Principle- When sidebending is attempted from non-neutral (hyperflexed or hyperextended) position, rotation must precede sidebending to the same side. c. 3rd Principle - Motion introduced in one plane limits and modifies motion in the other planes. Diff b/t physiologic findings and somatic dysfxn? a. Physiologic motion becomes somatic dysfunction if the segments do not return to “normal” after completion of motion. They may be pure sagittal plane dysfunctions, neutral dysfunctions, or flexed or extended non neutral dysfunctions. Review and discuss the indications and contraindications for HVLA to the lumbar spine. I. II. III. IV. Definitions a. HVLA (thrust) approach is characterized by positioning to engage the restrictive barrier, followed by a corrective maneuver to move through the barrier. b. Accurate diagnosis is the key to performance of HVLA (thrust) techniques. c. Positioning against the restrictive barrier in all planes is followed by a rapid and brief corrective thrust. d. HVLA (thrust) techniques can be taught and learned easily. The necessary motor coordination for effective use requires extensive practice and experience. e. “An osteopathic technique employing a rapid, therapeutic force of brief duration that travels a short distance within the anatomic range of motion of a joint, and that engages the restrictive barrier of an articular somatic dysfunction in one or more planes of motion to elicit release of restriction. Also know as thrust technique.” Has a. Distinct barrier mechanics b. Within anatomic ROM (actually physiologic ROM) c. Engages restrictive barrier (within physiologic ROM) d. Goal: 1. move restricted joint through its dysfunctional barrier. 2. restore appropriate physiologic motion to the dysfunctional joint. Steps to HVLA Thrust a. Gently position patient against restrictive barrier. b. Apply constant gentle pressure against barrier. c. Encourage patient to breathe and relax. d. Apply a gentle high velocity, low amplitude thrust through restrictive barrier. e. Reposition patient to neutral position and reassess. Contraindications to HVLA a.

Potential test types question: 46 yo has low back pain, no radicular, you put them into Ext and L thumb is post and inferior…how would you tx w/ an indirect tx? Facilitated Postional Release (FPR) a. Neurophysiology i. “immobility of a lesioned segment was initiated or maintained by an increased gain in gamma motor neuron activity of that segment” - Korr. ii. “an inappropriately high gain-set of the muscle spindle results in changes characteristic of somatic dysfunction” - Bailey. iii. TEST QUESTION FROM ANY OF THIS IN BOLD: iv. primary neurophysiologic mechanism affected by FPR is thought to be the relationship between Iα-afferent and γ-efferent activity v. If the dysfunctional segment is positioned appropriately, the fibers may return to normal length, which decreases tension in the fibers 8 IV. vi. This reduced tension in the area of the muscle spindle eliminates the afferent excitatory impulses vii. This “quiets” the hyperactive gamma motor gain, reducing the stretch stimuli, and eliminates the reflex activation of the α-motor neuron viii. This allows the tension and hypertonicity of the muscles to “reset” ix. Think: afferents, efferents, gamma gain 1. Shorter than counterstrain (which is like 90 - to 120- sec vs FPR 3-5 sec) b. Benefits i. Easily Applied ii. Non-traumatic iii. Effective & Efficient iv. When performed properly patients report immediate relief of point tenderness/pain. c. Tx is classified into 2 categories i. one directed at normalization of palpable abnormal tissue texture ii. to influence deep muscle involved in joint mobility d. Tx’s on ppt slides..from lab i. Lumbar Soft Tissue ii. Lumbar Flexion iii. Lumbar Extension iv. There are prone and seated tx, seated is prolly easier to work with e. INDICATION = myofascial or articular somatic dysfxn f. RELATIVE CONTRAINDICATIONS (no true absolute indications) i. Moderate to severe joint instability ii. Herniated disc where the positioning could exacerbate the condition iii. Moderate to severe intervertebral foraminal stenosis, especially in the presence of radicular symptoms at the level to be treated if the positioning could cause exacerbation of the symptoms by further narrowing the foramen iv.

Certain congenital anomalies or conditions in which the position needed to treat the dysfunction is not possible (e.g., ankylosis) vi. Vertebrobasilar insufficiency JONES STRAIN/COUNTERSTRAIN a. Neurophysoiology i. As with FPR, the primary neurophysiologic mechanism affected by counterstrain is thought to be the relationship between Iα-afferent and γ-efferent activity ii. If the dysfunctional segment is positioned appropriately, the fibers may return to normal length, which decreases tension in the fibers iii. This reduced tension in the area of the muscle spindle eliminates the afferent excitatory impulses iv. This “quiets” the gamma motor gain, reducing the stretch stimuli, and eliminates the reflex activation of the α-motor neuron v. This allows the tension and hypertonicity of the muscles to “reset” b.

Have tender point at the apex of the curve iii. SB & R according to Rx formula (for Type I and Type II dysfunctions - remember this is indirect) iv. Shutdown the tender point at least 70% 1. This position is called the position of comfort (subjective) or mobile point (objective) v. Tender point: Maintain light contact vi. Hold positioning & tender point for: 1. 90 seconds: everything except ribs 2. 120 seconds: Ribs vii. Recheck tenderness during treatment viii.

FOR THE S/CS POSITIONING, PUT IN THE POSITION OF THE POSITIONAL DIAGNOSIS TO SHUT DOWN THE TENDER POINT PIRIFORMIS SYNDROME a. What i. Neuromuscular condition characterized by hip and buttock pain ii. Most frequently during the 4-5th decades iii. Incidence rates among patients with low back pain vary widely, from 5% to 36% iv. Muscle acts as an external rotator, weak abductor, and weak flexor of the hip. Provides postural stability during ambulation and standing v. Attachments: 1. Anterior surface of the sacrum 10 VI. 2. Attaches to the superior medial aspect of the greater trochanter vi. This syndrome is often overlooked in clinical settings because its presentation may be similar to that of lumbar radiculopathy, primary sacral dysfunction, or innominate dysfunction b. Causes i. May have a peripheral neuritis of the sciatic nerve caused by an abnormal condition of the piriformis muscle Symptoms: 1. Pain with sitting, standing, lying >15 min 2.

With patient prone locate and monitor the tender point ii. flex the hip on the dysfunctional side to ~135*, iii. while monitoring the tender point add external rotation and ABduction until you achieve a 70% reduction in pain iv. Hold for 90 seconds then return to neutral v. Recheck PSOAS Syndrome a. What i. Psoas syndrome is a neuromuscular condition characterized by pain in lower back and may radiate to hip or groin ii.

Typically flexion dysfunction of L1 or L2 2. Compensatory extension dysfunction in L-S spine vii. Sacral dysfunction 1. Rotate away from dysfunctional side c. Maverick Points i. Roughly 5% of counterstrain tender points will not respond to the typical pattern of treatment (maybe just putting in position of ease to relax the TP and tx it there) ii. Try putting the patient in the opposite position and treating the tender point Or iii. Put the tender point in it’s position of ease and treat it Summary of Point Types Lecture 4: Osteopathic Abdominal Exam (Cannon) I. II.

Look for ecchymosis, Grey Turner’s sign – is massive ecchymosis noted on the flanks from pancreatitis (to bruising of the flanks.This sign takes 24–48 hours. It can predict a severe attack of acute pancreatitis, with mortality rising from 10% to 40%. It is a sign of retroperitoneal hemorrhage ) and Cullen’s sign – a bluish discoloration of the umbilicus from hemoperitoneum (presence of blood in the peritoneal cavity. The blood accumulates in the space between the inner lining of the abdominal wall and the internal abdominal organs.) c. Look for hernias of umbilical, inguinal femoral origin and at the sites of any scars. Have the patient cough to increase intra-abdominal pressure. d. Valsalva is more commonly performed to attempt to palpate a hernia. ii. Sister Mary Joseph nodule 13 1. Sister Mary Joseph nodule or node, also called Sister Mary Joseph sign, refers to a palpable nodule bulging into the umbilicus as a result of metastasis of a malignant cancer in the pelvis or abdomen. 2.

Telangectasias iv. Panniculitis v. Lunula vi. Melanin deposits vii. Ranson’s Criteria – predicts mortality in pancreatitis b. Auscultation i. Evaluate bowel sounds, listen for 30 seconds to 2 min. ii. Normal bowel sounds are every 5-10 seconds and are high pitched, if no sounds after 2 min “absent bowel sounds” may be from ileus iii. Low pitched rumbling sounds of gas moving through the intestines are known as borborygmi. iv. Listen to each quadrant- bruits may signify renal artery stenosis. c. Percussion i. Determine the presence of gas, fluid or mass ii. Liver, start mid-clavicular and go downward; over the liver is dull and over colon more tympanic; avg. length of liver @ 10cm iii. Spleen; in posterolateral wall of abdominal cavity hidden by rib cage (Traube’s space ; 6th rib superiorly, axillary line laterally, and costal margin inferiorly) dullness in this space may be a sign of splenic enlargement iv. Ascites – identify area of tympany (gas) and dullness (ascites); have pt. change position and dullness will shift to dependent position (Shifting Dullness) v. Ascites – indentified by fluid wave. Pt’s hand indents subcutaneous adipose tissue to prevent impulse transmission; examiner taps one flank while palpating the other . Detection of a fluid wave indicates ascites . May see false positive in obese pt’s. vi. May see bulging flanks if enough fluid is present to push flanks outward d. Palpation i. Chapman’s points 1. Appendicitis – tip of rib 12 on R 2.

Distal 1/3rd of the transverse colon 2. Descending colon 3. Sigmoid colon 4. Rectum iii. Location: Midline along linea alba. Above umbilicus but below superior mesenteric iii. Light palpation 1. to help identify muscle spasm and tenderness. Use the flat part of hand or finger pads, not finger tips. Lift hand do not slide. 2. Rigidity is involuntary spasm of abdominal wall (does not relax with expiration) and indicates diffuse or localized peritoneal irritation. iv. Deep palpation 1. Used to estimate organ size and detect masses, bottom hand flat with upper hand exerting force with finger tips. May wish to have pt flex knees to relax muscles. 2. Guarding – any voluntary or involuntary muscle spasm (cold hands) 3. Rebound tenderness (referred)– peritoneal irritation caused by palpating deeply and slowly in an area away from the suspected area of inflammation, the palpating hand is quickly removed and a sensation of pain is felt at the area of inflammation. v. Liver palpation 15 1. Hooking – place both hands at area of dullness , lift inward and upward while pt. inhales. 2. Liver tap – place left hand in RUQ and hit with fist of R. hand. Pain may be felt with inflammatory processes of liver and GB. 3. Rovsing’s Sign ; pain produced in RLQ when palpating the LLQ 4.

Use fist to gently hit area on both sides of CVA, pt usually seated. Pain elicited in pyelonephritis viii. AORTA 1. A periumbilical or upper abdominal mass with expansile pulsations that is 3 cm or more wide suggests an AAA. Sensitivity of palpation increases as AAAs enlarge: for widths of 3.0-3.9 cm, 29%; 4.0-4.9 cm, 50%; ≥5.0 cm, 76%.41 2. Screening by palpation followed by ultrasound decreases mortality, especially in male smokers 65 years or older. Pain may signal rupture. Rupture is 15 times more likely in AAAs >4 cm than in smaller aneurysms.41 e. Rectal exam i. may be done with pt in standing bent , LLR, or supine positions. ii. Pt is asked to relax at first and then strain to examine for hemorrhoids. 1. Use one hand to hold buttocks and with gloved and the other hand, that is lubricated, to place a finger in anal canal.

An indirect technique in which the tissue being treated is positioned at a point of balance, or ease, away from the restrictive barrier b. To treat the strain, the physician counters the strain by reintroducing the original strain, which is the position of ease c. Counterstrain is based on identifying tender points and positioning the patient to eliminate the tenderness. d. Explained i. An event produces a rapid lengthening of a muscle ii. Afferent feedback indicates possible myofascial damage from a strain 1. Initial “strain” of agonist mm 2. “Panic” lengthening of antagonistic mm iii. Body attempts to prevent damage by rapidly contracting these tissues (shortening the agonist) 22 VI. VII. VIII. IX. iv. This lengthens the antagonist v. Rapid shortening of the agonist and lengthening the antagonist produce an inappropriate reflex producing a tender point in the antagonist muscle. e. Jones TPs may be found in muscle belly, tendinous attachments and ligaments Trigger vs Tender points a. TRIGGER: Characteristic pain pattern, Located in muscle tissue, Locally tender, Radiating pain pattern, Taut band of tissue b.

Contact TP & rotate away 90º c. Find it, fold it, hold it, recheck! Cervical SCS – posterior TPs are on occiput or assoc w/ tip of the spinous processes or lateral to spinous processes (ie, PC3 TP – eSARA) a. Indication for Treatment This procedure is appropriate for somatic dysfunction at C3 to C7 b. Tender Point Location The tender point lies at PC3 to PC7 posterolateral, at lateral surface of the articular process associated with the dysfunctional segment (Fig. 9.36). c. Treatment Position The physician extends the head and neck to the level of the dysfunctional segment with minimal to moderate side bending directed at the segment and minimal to moderate rotation away. The physician fine-tunes. Facilitated Positional Release (FPR) – indirect myofascial release tx. The component region of the body is placed into a neutral position, diminishing tissue and joint tension in all planes, and an activating force (compression or torsion) is added a. Ex: superficial muscle hypertonicity on RIGHT i. Patient may need to move back slightly as DO supports head. ii. Thumb, palm, and middle finger cradle the neck. Middle finger monitors area to be treated. iii. Gently bend head forward to flatten the cervical lordosis. iv. Apply axial compression caudally – just enough to be felt at pad of finger. Then bend neck slightly back and SB toward finger. v. Hold position for 3 seconds and gently release. vi. Reevaluate.

Carry to the restrictive barrier. ix. Reevaluate. Ligamentous Articular Strain = goal of treatment is to balance the tension in opposing ligaments where there is abnormal tension present a. In other words = DISENGAGE, EXAGGERATE, BALANCE i. Disengagement: Compress or decompress the joint or fascial plane, increasing pressure or traction until you are able to move the injured part. ii. Exaggeration: Carry the injure part back to the original position of injury by: rotating, flexing, or sidebending or “side-shifting” until a balance point or “Still point” iii. Balance: Maintain the area of dysfunction in the position of injury (at the balance point) until a release occurs. Balanced ligamentous tension a. All joints in the body are balanced ligamentous articular mechanisms. b. Ligaments provide proprioceptive information that guides the muscle response for positioning the joint. c. Ligaments guide the motion of the joints. d. Explained i. When a normal joint is at rest in the neutral position muscular, ligamentous and fascial tension are minimal and they are “balanced.” (balanced ligamentous tension). ii. As you move away from the neutral point tension gradually increases until you reach the physiologic barrier. iii. Between physiologic and anatomic barriers, tension increases more rapidly. As you continue this motion a “springy” resiliency (“end feel”) is palpated which gets less & less as you approach the anatomic barrier. iv. The anatomic barrier is very firm and if challenged will be very painful or traumatic. 25 XVIII. v. Our treatments are directed toward or away from the restrictive barrier which is PRIOR to the physiologic barrier. Actually represents lost motion which is within the physiologic or active range of motion. When you do direct OMT you are NOT moving through the anatomic barrier. e. Ex: supine, indirect, respiratory force BLT C2-C3 RLSL f. Ex: fibular hear dysfxn utilizing LAS/BLT i. Contact fib head with pad of thumb and press inferiorly ii. Invert foot, balance b/t your 2 hands until a release occurs Myofascial release = System of dx & tx first described by A.T. Still, which engages the continual palpatory feedback to achieve release of myofascial tissues. a. Direct-barrier engaged and tissue is loaded with a constant force until tissue release occurs. b. Indirect-dysfunctional tissues are guided along the path of least resistance until free movement is achieved. c. Example: Thoracic myofascial release i. Lecture 6: OMT for GI I. II. Anatomy a. The region of the trunk below the thoracic diaphragm i. Consists of two parts 1. Upper part – abdomen proper 2. Lower part – lesser pelvis ii. These two areas are continuous at the plane of the inlet of the lesser pelvis 1. Inlet is bounded by the sacral promontory, arcuate lines of the innominates, pubic crests, and upper border of the symphysis pubis. b. Abdomen proper i. Superiorly: thoracoabdominal diaphragm ii. Inferiorly: becomes continuous with the pelvis iii. Anteriorly: abdominal muscles – rectus abdominis, pyramidales, internal/external obliques and transversus abdominis iv.

A type of somatic pain - directly over the inflamed organ ii. Produced by direct contiguous irritation of the parietal peritoneum and the abdominal wall iii. Responsible for rebound tenderness and abdominal guarding associated with more severe abdominal pain d. Neurological Structures i. Sympathetics 1. Primary sympathetic fibers for innervation of all organs below the diaphragm (except descending colon and pelvic organs) pass from cells in the thoracic spinal cord *through the thoracoabdominal diaphragm* 2. They enter the celiac, superior mesenteric and inferior mesenteric collateral ganglia where they synapse 3. Postganglionic fibers continue on to innervate specific groups of organs in the abdomen and pelvis 4. Descending colon receives sympathetics from lumbar splanchnic nerves via inferior mesenteric ganglion; pelvis receives sympathetics from sacral splanchnic nerves which arise from the sympathetic trunk ii. Parasympathetics 1. Supplied from the craniosacral outflow a. Two divisions to gastrointestinal tract i. Vagus nerve (CN X) 1. Main nerve involved 2.

What = A system of reflex points that present as predictable anterior and posterior fascial tissue texture abnormalities (plaque-like changes or stringiness of the involved tissues) assumed to be reflections of visceral dysfunction or pathology 1. Reflexes are located deep to the skin and subcutaneous tissue and most often lying on the deep fascia or periosteum 2. Vary in size from pea to size of an almond 3. For a CR point to be positive, both anterior and posterior points should be present 4. Use the anterior points initially for diagnostic purposes as they are more widespread and then confirm by finding the posterior CR 5. Vary in tenderness from mild to almost unbearable 6. Classic treatment is rotary stimulation for 20 to 60 seconds 30 ii. GI ANTERIOR iii. GI POSTERIOR Iv. Chapman’s point of colon 1. Note the colon is flipped DOWN iv. Summary 1. GI system may be effected by several mechanisms 31 2. Primary organ disease will cause viscerosomatic reflexes resulting in somatic dysfunction 3. Somatic dysfunction will produce somatovisceral reflexes influencing organ irritation and dysfunction 4. **Treatment of the primary organ problem will not always resolve the somatic dysfunction and so both should be treated 5. May also have viscerovisceral dysfunctions, in which case both organs should be addressed V. VI. VII. Tx GOALS a. Address asymmetries, motion restrictions and tissue texture abnormalities that are viscerosomatic reflections of homeostatic disturbances b. Decrease or eliminate pain c.

Improve organ function j. Alter any or all of the previously mentioned situations as either contributing to, or predictive of, future health problems Tx a. General i. Treatment of the autonomic system is aimed at the level corresponding to the innervation of the facilitated segment ii. The primary and secondary areas should be treated (e.g. gastric ulcer with medication and vagus nerve to treat excess acid secretion) iii. Sympathetic and parasympathetic levels will correspond with the organ involved b. Approaches to using OMT on the ABDOMEN i. Spinal Approach 1. Should be treated in order to improve spinal motion and ultimately restore normal nerve function in segmentally related areas 2. Numerous manipulative methods can be used ii. Peripheral Approach - Goal of techniques are to improve the ability to move fluids throughout the abdominal region, thus improving the delivery of oxygen, nutrients, and arterial blood to affected areas, and facilitating venous and lymphatic drainage for the removal of the waste products of cellular metabolism 1. Thoracic/pedal lymphatic pump 2. Diaphragmatic redoming 3. Thoracic inlet and pelvic diaphragm releases 4. Chapman reflex treatments iii. Direct Approach 1.

ATELECTASIS 32 i. What 1. Incomplete expansion of the lungs due to alveolar collapse 2. Most frequent pulmonary complication after surgery 3. Natural response of patient after surgery is abdominal wall splinting and shallow breathing 4. This prevents full diaphragmatic excursion, so alveoli at the lung bases are not expanded, decreasing oxygen exchange in these areas ii. Clinical presentation 1. Low O2 saturation 2. Increased respiratory rate 3. Respiratory distress 4. Increased respiratory secretions 5. Decreased mental status iii. Tx 1. Incentive Spirometer – try to get alveoli to pop open 2.

Due to visceral sensory afferents in the splanchnic and pelvic nerves that increase inhibitory sympathetic activity in the GI tract 2. Post-operatively due to an inflammatory response from intestinal manipulation during surgery that results in muscle dysfunction 3. Inhibitory neurotransmitters such as nitric oxide and substance P slow gut motility iii. Clinical presentation 1. Abdominal distention 2. Diffuse abdominal pain 3. Nausea and/or vomiting 4. Inability to pass flatus or stool 5. Inability to tolerate PO diet iv. MUST rule out mechanical small bowel obstruction, as this may require surgical intervention 1. Imaging, such as KUBs or abdominal CT scans, will help differentiate between the two v. Tx 1. Keep patient NPO (“nil per os” – nothing by mouth) 2. Start IV fluids 3. NG tube placement if persistent vomiting or abdominal distention to decompress the stomach 4. Limit opioid pain medications due to constipation 5. OMT! a. Studies dating back to 1965 demonstrate importance and efficacy of OMT in interrupting inappropriate viscerosomatic-somatovisceral cycles i. Numerous studies since which have now shown decreased hospital length of stay 33 ii. Most recent showed a decreased LOS (LENGTH OF STAY) from 11.5 days in non-OMT group to 6.1 days in OMT group!!a 5 DAY DIFFERENCE. Lecture 7: Indirect T-Spine (Banhsaly) I. II. III. Anatomy a. 3 anatomical regions i. Upper T1-4 ii. Middle T4-8 iii. Lower T8-L1 b. 4 functional divisions – outflow of sympathetics i. T1-4: head and neck ii. T1-6: heart and lungs iii. T5-9: Stomach, duodenum, liver, gall bladder, pancreas, and spleen iv. T10-11: Remainder of the small intestines, kidneys, ureters, gonads, and right colon c. Thoracic Spinous Process i. Increasingly caudad from T1-T9 and back to almost anteroposterior orientation from T10-12 1. Facet orientation determine the motion of the vertebral segments a. Remember BUM, BUL, BUM i. Cervical Superior Facets: Backward,Upward,Medial ii. Thoracic Superior Facets: Backward,Upward,Lateral iii. Lumbar Superior Facets: Backward,Upward,Medial Fryette a. Law I i. In the neutral position 1. Sidebending precedes rotation 2. Sidebending and rotation occur to the opposite side 3. Typical of group dysfunctions: T1-4 NSRRL b. Law II 1. In the non-neutral (flexed or extended) position 2. Rotation precedes sidebending 3. Sidebending and rotation occur to the same side 4. Typical of a single vertebral dysfunction: T4 FSRR Indirect Method a. General i. A manipulative technique where the restrictive barrier is disengaged ii. The dysfunctional body part is moved away from the restrictive barrier until tissue tension is equal in one or all planes and directions b. Adjust tone through i. Gamma efferent chain ii. Nociceptive input iii. ANS modification c. Changes occur in all systems i. Muscular ii. Visceral iii. Neuro & neuroendocrine iv. Vascular v. Lymphatic vi. Metabolic 34 IV. e. Inherent forces i. Exaggeration 1. the dysfunctional component is carried away from the restrictive barrier and beyond the range of voluntary motion to a point of palpably increased tension ii. Respiratory force 1. Practitioner-directed inhalation and/or exhalation by the patient to assist the manipulative treatment process iii. Patient cooperation 1. Voluntary movement by the patient (on instruction from the practitioner) to assist in the palpatory diagnosis and treatment process JCSC a. General i. indirect technique in which the tissue being treated is positioned at a point of balance, or ease, away from the restrictive barrier ii. To treat the strain, the physician counters the strain by reintroducing the original strain, which is the position of ease iii. based on identifying tender points and positioning the patient to eliminate the tenderness. b. Know differences c. Mechanism of Tx/Effects i. Many postulates as to how it works 1. Most involve α Ia afferent and ɣ efferent relationships and nociception 2. Golgi tendon organs may be involved, bioelectric phenomena, lymphatic and/or interstitial exchange ii. Proposed Effects 1. Normalize muscle hypertonicity – reduce ɣ gain 2. Normalize facial tension 3. ↓ joint restriction by decreasing muscle tone 4. ↑ blood circulation due to reduction of spasm 5. ↓ pain – normalize thresholds 6. ↑ strength – no joint spasm to work against d. Indication for JSCS i. Presence of a tender point 1. Can be acute or chronic 2. May be associated with a viscerosomatic reflex ii. Pt may be hesitant about other types of OMT iii. Frail patient 35 iv. Trial of OMT to assess pt’s tolerance e. CONTRAINDICATIONS – rare i. Fracture in the area ii. Torn ligament in the area f. Tx in JSCS i. Identify and label tender point as 10/10 or 100% ii. Passively position the body into tissue laxity (position of comfort) and retest for tenderness 1. Fine tune in all planes of motion until tenderness is minimized to 0/10 or max of 3/10 iii. Hold for 90s, maintain finger contact to monitor tissue texture changes. REDUCE PRESSURE! iv. SLOWLY and PASSIVELY return the body to neutral v. Retest for tenderness and tissue texture g. Tenderpoints i. anterior **7-12 are BILATERAL ii. Posterior (These are important, tx positions are different. She will give us the specific tenderpoint to treat for the test) 1. Midline * a. On the inferior tip of the spinous process 2. Posterior * [Inferolateral] a. Inferior lateral aspect of the spinous process b. Bilateral 3. Lateral * [Transverse Process] a. On transvers process b. Bilateral 36 V. Facilitated Positional Release (FPR) a. General i. A system of indirect myofascial release treatment. The component region of the body is placed into a neutral position, diminishing tissue and joint tension in all planes, and an activating force (compression or torsion) is added. b. Indications i. Back pain ii. Chest wall pain c. CONTRAINDICATION = ACUTE FRACTURE d. Directions (think – FLATTEN THE CURVE, like T spine is a natural kyphosis so EXTEND IT) i. Identify tension related to restricted motion ii. Place the joint or region in its neutral position (Flatten the curve) iii. Add compression or torsion to facilitate tissue laxity iv. Palpate the tension and move the joint or region into its position of laxity for all planes v. Hold position for 3-5s until tension release is completed vi. Slowly return to neutral vii. Retest for tension or motion e. Step 1: Superficial Muscle Hypertonicity (seated technique) i. Find the area of hypertonicity in T-spine and place finger(s) in that area to monitor ii. Flatten out thoracic kyphosis by extending to monitored area iii. Instruct patient to sit up straight, push out chest if needed iv. Apply compression to area, vector of force is aimed straight down parallel to the spine. v. Side bend down to monitored area while maintaining compression and extension. vi. Hold for 3-5 seconds then release. vii. Recheck f. Step 2: Somatic dysfxn (Extension – seated technique) i. Physicians monitoring finger is at the posterior transverse process ii. Pt is instructed to sit up straight until the thoracic kyphosis flattens slightly iii. If necessary advised pt. to push out chest until backward bending is created up to monitoring finger iv. Physician applies compression, vector of force is straight down parallel to the spine 37 VI. VII. VIII. v. Maintaining backward bending and compression, sidebend the pt. to increase extension and add rotation to the sidebending component * vi. Hold for 3-5 seconds vii. Recheck viii. * For flexion dysfunction, flexion of spine is added after the compressive force is applied. Otherwise the technique is the same as for an extension dysfunction g. Step 2: Somatic Dysfxn (extension – PRONE technique) i. Physician places the index finger of his cephalad hand at the posterior transverse process of dysfunctional segment 1. With pt. prone, mild flattening of the thoracic kyphosis is usually created 2. You can use a pillow if needed ii. With caudad hand, physician grasps the patient’s shoulder over the acromion process 1. With hand on the superior aspect of the shoulder girdle, pull the shoulder, parallel to the table and towards patients feet, until force is felt at the monitoring finger. 2. This creates sidebending iii. Maintaining this force, physician straightens up, thereby pulling the patient’s shoulder backward off of the table, creating rotation iv. These combined motions create compression, extension, side-bending, and rotation up to the monitoring finger v. Hold for 3-5 seconds vi. Recheck Myofascial Release (MFR) – DO SOFT TISSUE THEN MFR BEFORE YOUR OTHER TECHNIQUES a. Def i. System of dx & tx first described by A.T. Still, which engages the continual palpatory feedback to achieve release of myofascial tissues. 1. Direct-barrier engaged and tissue is loaded with a constant force until tissue release occurs. 2. Indirect-dysfunctional tissues are guided along the path of least resistance until free movement is achieved b. Indications i. Restricted rotation ii. Back pain iii. Chest wall pain iv. Rib restriction v. Shoulder pain c. CONTRAINDICATION = ACUTE THORACIC FRACTURE Balanced Ligamentous Tension (BLT) a. General i. All joints in the body are balanced ligamentous articular mechanisms. ii. Ligaments provide proprioceptive information that guides the muscle response for positioning the joint. iii. Ligaments guide the motion of the joints. b. See directions for lab – “try to find the sweet spot – errything melts and feels right” Ligamentous Articular Strain (LAS) - manipulative technique in which the goal of treatment is to balance the tension in opposing ligaments where abnormal tension is present a. Tx i. Identify ligament or myofascial tension ii. Press into or apply traction to the tense area to engage the tissues iii. Slowly move the part of the body into its position of laxity for all planes 38 iv. Maintain the position of laxity using balanced pressure and follow any tissue release until completed or inherent motion ( cranial rhythmic impulse) is palpated v. Retest for tension b. Mostly for ILL or Piriformis. Providing a pressure equal to what’s being produced in the muscle and balance it, a fine balance (similar to inhibition but in inhibition you use more pressure)
