4 Tenets of Osteopathic Medicine
A
- The person is a unit of body, mind, and spirit
- The body is capable of self-regulation, self-healing, and health maintenance
- Structure and function are reciprocally interrelated
- Rational Treatment is based upon understanding and implementing the other 3 tenets
7
Q
Somatic Dysfunction

14
Q
Types of Tissue texture abnormalities
A
– Bogginess – Thickening – Stringiness – Ropiness – Firmness (hardening) – Temperature change – Moisture change
15
Q
Bogginess
A
A tissue texture abnormality characterized principally by a palpable sense of sponginess in the tissue, interpreted as resulting from congestion due to increased fluid content.
16
Q
Tone
A
Normal feel of muscle in the relaxed state. Contrast with:
– Hypertonicity (at the extreme = spastic paralysis) or
– Hypotonicity (aka flaccid paralysis when no tone at all).
17
Q
Contraction
A
Normal tone of a muscle when it shortens or is activated against resistance
18
Q
Contracture
A
Abnormal shortening of a muscle due to fibrosis. Most often in the tissue itself, often result of chronic condition. Muscle is no longer able to reach its full normal length.
19
Q
Spasm
A
Abnormal contraction maintained beyond physiologic need. Most often sudden and involuntary muscular contraction that results in abnormal motion and is usually accompanied by pain and restriction of normal function.
20
Q
Ropiness
A
Hard, firm, rope-like or cord-like muscle tone. Usually indicates a chronic condition.
21
Q
TTC: Vascular, Sympathetic, Musculature Acute
A
- V: Inflamed vessel wall injury, endogenous peptide released
- S: Local vasoconstriction overpowered by local chemical release, net effect is vasodilation
- M: Local increase in tone, muscle contraction, spasm – mediated by increase spindle activity
22
Q
TTC: Vascular, Sympathetic, Musculature Chronic
A
- V: Sympathetic tone increases vascular constriction
- S: Vascoconstriction, hypersympathetic tone, may be regional
- M: Decreased muscle tone, flaccid, mushy, limited ROM due to contracture
23
Q

24
Q
Restriction of Motion
A
A resistance or impediment to movement
25
Barriers to ROM
1. Anatomic Barrier - the limit of motion imposed by
anatomic structure; the limit of passive motion.
2. Physiologic Barrier - the limit of active motion.
3. Elastic Barrier - the range between the physiologic and anatomic barrier of motion in which passive stretching occurs
before tissue disruption; aka, the area that “warms up” with stretching
4. Restrictive Barrier - a functional limit that abnormally diminishes the normal physiologic range.
26
Active vs. Passive ROM
* AROM: Patient motivated and patient must give maximum effort!
* PROM: Patient must relax fully and you must “block the linkage” of associated structures
Normal: PROM>AROM
27
Barrier "end feel" Characteristics
```
-The palpatory experience or perceived quality of motion when a joint is moved to its limit – a barrier is approached Normal end feel
• Examples
-Early muscle spasm
-Late muscle spasm
-Hard capsular
-Soft capsular
```
28

29
Pain, Visceral Function, Visceral Dysfunction: Acute
1. P: Sharp, severe, cutting
2. VF: minimal somatovisceral effects
3. VD: may or may not be present; if trauma is severe, it is often present
30
Pain, Visceral Function, Visceral Dysfunction: Chronic
1. P: Dull, ache, paresthesias (tingling, burning, gnawing, itching)
2. VF: Somatovisceral effects common
3. VD: Often involved in somatic dysfunction
31
TTA, Asymmetry, Restriction, Tenderness: Acute
1. Red, swollen, boggy, increased tone
2. Present
3. Present, painful with motion
4. Sharp pain
32
TTA, Asymmetry, Restriction, Tenderness: Chronic
1. Dry, cool, ropy, pale, decreased tone
2. Present, compensation occurs
3. Present, maybe not. Guarded or “Empty”
4. Dull, achy pain
33
Tenderpoints
small discrete hypersensitive areas within myofascial structures that result in localized pain
34
Trigger points
mall discrete hypersensitive areas within myofascial structures - palpation causes referred pain away from site.

What does "soft tissue" entail?
```
Living tissues of the body other than bone.
– Fascia
– Muscles
– Organs
– Nerves
– Vasculature
– Lymphatic
```
97
Fascial Anatomy
Generally speaking, these connective tissue layers are composed of collagen fibers (and occasionally also elastin fibers) in an amorphous matrix of hydrated proteoglycans (PGs), which mechanically links the collagen fiber networks in these structures.
98
Fascia is not
* Tendons
* Ligaments
* Aponeuroses
99
Fascia is
• A complete system with blood supply, fluid drainage & innervations
– Thus, fascia comprises the largest organ system in the body • Composed of irregularly arranged fibrous
elements of varying density
• Fn: Involved in tissue protection &
healing of surrounding systems
100
Pannicular Fascia
Outermost layer of fascia derived from somatic mesenchyme & surrounds entire body with exception of the orifices; outer layer is adipose tissue & inner layer is membranous & adherent, generally, to the outer portion
• Axial & Appendicular Fascia (aka investing layer)
• Meningeal Fascia
• Visceral Fascia
101
Axial & Appendicular Fascia
Internal to the pannicular layer; fused to the panniculus and surrounds all of the muscles, the periosteum of bone & peritendon of tendons
102
Meningeal Fascia
Surrounds the nervous system; includes the dura
103
Visceral Fascia
Surrounds the body cavities (pleural, pericardial & peritoneum
104
What are the four types of fascia layers?
1. Pannicular
2. Axial and Appendicular
3. Meningeal fascia
4. Visceral
105
Omnipotent aspect of fascia
-Provides for mobility and stability of the
| musculoskeletal system
106
Omnipresent aspect of fascia
it's everywhere
107
Omniscient aspect of fascia
•Approximately 20% of cutaneous high-threshold mechanoreceptors supplying the skin also have receptive fields in the subcutaneous tissue...the loose fascia.
•Stretch receptors for muscles & Proprioception (balance)
– Only 25% in the muscle
– 75% consists of free endings in fascia
•80% of the C fibers are polymodal
-Liquid crystal-like properties
– Piezoelectricity
108
Viscoelastic Material
Any material that deforms according to rate of loading and deformity
109
Stress-Strain
* Stress is the force that attempts to deform a connective tissue structure.
* Strain is the percentage of deformation of a connective tissue.
110
Hysteresis
* The difference between the loading and unloading characteristics represents energy that is lost in the connective tissue system; this energy loss is termed hysteresis.
* Stretching connective tissue into its’ plastic deformational range will bring about a lengthening of the tissue.
111
Creep
Connective tissue under a sustained, constant load (below failure threshold), will elongate (deform) in response to the load.
112
Ease
* The direction in which the connective tissue may be moved most easily during deformational stretching.
* Palpated as a sense of tissue “looseness”, or laxity or greater degree of mobility.
113
“Fascial Sweater”
Fascial restrictions in one area of the body, will create connective tissue restrictions (pulls) at a distance away from the site of the initial restriction. The result is abnormal myofascial & joint mobility.
114
Sherrington’s Law
When a muscle receives a nerve impulse to contract, its antagonists receive simultaneously an impure to relax
115
Compensatory Patterns
- Common (80%): L/R/L/R
| - Uncommon (20%): R/L/R/L
116
Transition Zones of the Spine

- Pelvic diaphragm
118
Stretch
increase distance between the origin and insertion
119
Knead
Repetitive pushing of tissue perpendicular to muscle fibers
120
Inhibition
* Push and hold perpendicular to the fibers at the musculotendinous part of hypertonic muscle.
* Hold until relaxation of tissue
121
Inherent Forces:
using the body’s PRM (primary respiratory mechanism)
122
Respiratory Cooperation
Refers to a physician directed, patient performed, inhalation or exhalation or a holding of the breath to assist with the manipulative intervention.
123
Patient Cooperation
the patient is asked to move in specific directions to aid in mobilizing specific areas of restriction
124
T.J. Ruddy, DO
“Ruddy’s Rapid Rhythmic Resistive Duction” 1914 – first published article – 1950’s Closed his EENT practice to focus on OMM
-Eye and cervical spine treatment
-Used rapid, repetitive contractions 1-2 per second
against resistance
125
Fred L. Mitchell, Sr., DO - 1959 Graduate Chicago
- Wrote about Muscle Energy Technique as early as 1948
- 1950’s-1960s taught courses with Paul Kimberly, DO entitled “The Pelvis and its Environs”
- 1970 taught a course in Iowa to 6 students (5 of whom became osteopathic college faculty)
- Fred Mitchell, Jr., DO has developed and amplified MET
126
Muscle Energy is:
```
-Voluntary contraction of patient
Restrictive Barrier
Varying levels of intensity
muscle
- In a precisely controlled direction
-Varying levels of intensity
-Against a distinctly executed counterforce
-Active Technique
= Patient contributes the corrective
force
- Direct Technique – positioned to the restrictive barrier
**Patient's motion is away from the barrier**
```
127
Isometric contraction
Contraction of a muscle with no change in distance between the origin and insertion
128
Concentric isotonic contraction
Contraction of a muscle with
| approximation of origin and insertion
129
Eccentric isotonic contraction
Contraction of a muscle with
| separation of origin and insertion
130
“Isolytic” contraction
– NON- PHYSIOLOGIC
| -Attempted concentric contraction, with an external force causing separation of origin and insertion
131
Post-Isometric Relaxation
**Most common form of MET**
-Muscle contraction increased tension in GTO
inhibition of muscle contraction
132
Joint mobilization using muscle force
- Restoration of motion to the articulation results in a gapping, or reseating of the distorted joint relations with reflex relaxation of the previously hypertonic musculature.
- Maximal muscle contraction that can be comfortably resisted by the physician
133
Respiratory assistance
- The muscular forces involved in these techniques are generated by the simple act of breathing. This may involve the direct use of the respiratory muscles themselves, or motion transmitted to the spine, pelvis, and extremities in response to ventilation motions. The physician usually applies a fulcrum against which the respiratory forces can work
- Exaggerated respiratory motion.
134
Oculocephalogyric reflex
• These eye movements reflexively affect the cervical and truncal musculature as the body attempts to follow the lead provided by eye motion
-Exceptionally gentle force
135
Reciprocal inhibition
- When a gentle contraction is initiated in the agonist muscle, there is a reflex relaxation of that muscle’s antagonistic group
- Think ounces not pounds of pressure
* *Ipsilateral--same side**
136
Crossed extensor reflex
- This form of muscle energy technique uses the learned cross pattern locomotion reflexes engrammed into the central nervous system. When the flexor muscle in one extremity is contracted voluntarily, the flexor muscle in the contralateral extremity relaxes and the extensor contracts.
- Think ounces not pounds of pressure
* *Contralateral--opposite side**
137
Isokinetic strengthening
- Where asymmetry of range of motion exists, there is also the potential for asymmetry in muscle strength. If there is shortening of an antagonist muscle, attend to that first.
- Once this is accomplished, further restoration of strength can be accomplished through the use of an Isokinetic contraction.
- Typically concentric contractions are used, where the muscle is permitted to shorten, but at a controlled slow rate.
- Sustained gentle pressure (10 to 20 lb of pressure)
138
Isolytic lengthening
- It is postulated that the vibration used here has some effect on the myotatic units in addition to mechanical and circulatory effects
- Maximal Contraction that can be comfortably resisted by the physician (30 to 50 lb of pressure)
139
Using muscle force to move one region of the body to achieve movement of another bone or region
- For some dysfunctions, it is often more effective to move one body structure by moving another body structure adjacent to it. Muscular force is used to move the first structure and that body part’s response to the muscle force is transmitted to yet another part of the body.
- Sustained gentle pressure (10 to 20 lb of pressure)
140
Isometric vs. Isotonic
1. Both use careful positioning
2. IM uses light to moderate contraction, IT uses hard to maximal contraction
3. IM uses unyielding counterforce, while IT counterforce permit controlled motion
4. Both use relaxation after contraction
5. Both use repositioning
141
Muscle energy techniques are used to
- balance muscle tone
- strengthen reflexively weakened musculature
- improve symmetry of articular motion
- enhance the circulation of body fluids (blood, lymph, and interstitial fluid)
- Lengthen a shortened, contractured, or spastic muscle group
- Versatile to use in combination with other osteopathic manipulative techniques

1. The physician positions the body part to be treated, at the position of initial resistance.
2. The patient is instructed in the intensity, duration, and direction of the muscle contraction.
3. The physician directs the patient to contract the appropriate muscle(s) or muscle group.
4. The physician uses counterforce in opposition to and equal to the patient’s muscle contraction.
5. The physician maintains forces until an appropriate patient contraction is perceived at the critical articulation or area. This generally takes 3 to 5 seconds.
6. The patient is directed to relax while the physician simultaneously matches the decrease in patient force.
7. The physician allows the patient to relax and senses the tissue relaxation with his or her own proprioceptors.
8. The physician takes up the slack permitted by the procedure. The slack is allowed by the decreased tension in the tight muscle, allowing it to be passively lengthened.
9. Steps 1 to 8 are repeated three to five times until the best possible increase in motion is obtained.
10. The physician reevaluates the original dysfunction.

Factors Influencing Successful Muscle Energy-Patient
-Contract too hard
-Contract in the wrong
direction
-Sustain the contraction for too short a time
-Do not relax appropriately following contraction
144
Factors Influencing Successful Muscle Energy-Operator
Not controlling the joint position in relation to the barrier movement
Not providing the counterforce in the correct direction
Not giving accurate instructions
Moving to a new joint position too soon after the patient stops contracting
145
Articulatory Approach is also called...
Springing techniques
- gentle and repetitive motions through the restive barrier
- applicable with the restive barrier in the joint or periarticular tissues
146
Articulatory Techniques are well tolerated by...
-Arthritic patients
-Elderly or frail
-Critically ill or post-operative patients
-Infants or very young patients
-Patients unable to cooperate
with instructions

Steps of Articulatory Technique
1. The physician should also be in a position of comfort.
2. The physician moves the affected joint or body part through its range of motion until the
restrictive barrier is engaged.
3. A gentle but firm force is applied carrying the body part a short distance through the restrictive barrier.
4. This force is applied rhythmically, typically 1 or 2 seconds of stretch followed by a similar time frame releasing that stretch. The joint is permitted to return to a point just short of its restrictive barrier
5. As the patient responds to the technique, the restrictive barrier will shift position within the physiologic range of motion. For each cycle of the applied technique, reengage the restrictive barrier and carry the affected body part a short distance further through that new barrier to normal motion
6. The applied forces should be comfortable for the patient. Some patients experience some discomfort, but it is recognized by the patient as a good discomfort
7. The technique is continued until the location of the restrictive barrier reaches a plateau; that is, no further increase in range of motion can be achieved by continuing the technique, or until full physiologic range of motion has been restored to the joint(s) being treated
148
MET vs. ART
1. Both are direct techniques
2. Activating force in MET is patient muscle contraction, and in ART it is physician directed motions
3. Patient Cooperation: required for MET, and relaxation for ART
4. Goal: alleviate SD for both
