Structure and Function
• We should look at, and study the body as a
whole, in structure and function
• Physiologically, one muscle does not function
independently of others
• Three types of muscle
– Skeletal, smooth and cardiac

3
Muscles and Force
• Muscle can change chemical energy (from
ATP) into mechanical energy
– Energy: the capacity to do work
• When muscle contracts, muscle tissue
transforms one form of energy into another
and it is able to produce force
• 2 Types of force
– Dynamic force: creates movement and change
– Static force: expends energy, but creates no
movement or noticeable change
• (like pushing against a wall)

Muscle Functions
• 4 major muscle functions
–
–
–
–
Movement production
Joint stabilization
Posture maintenance
Heat generation

Functional Characteristics
of Muscle
• Excitability: the ability to receive and respond
to a stimulus
– Massage stimulates the muscles, which in turn
stimulates the maintenance of homeostasis
• Contractility: the ability to shorten forcibly with
adequate stimulation
– The ability to contract allows the entire organism
to move

6
Functional Characteristics
of Muscle
• Extensibility: the ability to be stretched or
extended
– One group of muscles contracts, while the other
group lengthens
• Elasticity: the ability to recoil and resume the
original resting length after being stretched
– This also includes the ability to remember where
the movement began and to return to that position
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
7
Support function of muscle tissue
• The nervous system controls contraction
– skeletal and smooth muscle
– influences the rate of cardiac contraction
• The endocrine system
– produces hormones promote repair of muscle
tissue
• The circulatory system
– delivers nutrients and carries away waste
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
8
Functional Characteristics
of Muscle
• The digestive system
– breaks food down
– glucose  ATP  work
• The digestive, urinary and respiratory
systems
– eliminate waste products from muscle metabolism
• Lactic acid is the end product of muscle work
• Lactic Acid  Broken down through aerobic respiration
AKA the Kreb cycle OR
• Lactic Acid  or sent to the liver to be converted back to
glucose

9
Muscle Action
• Isometric
– Tension in
the muscle
with no
change in
movement
• Isotonic
– Concentric
– Eccentric

Length and Tension
• Direct link between
tension development
and length of the
muscle
• If shortened, or
lengthened beyond
optimum, tension
decreases

Energy Sources
• ATP
• Efficient contraction requires
– Glucose
– Oxygen: aerobic respiration
• Anaerobic respiration: no immediate oxygen
use
– Produces lactic acid
– Leads to oxygen debt

15
Types of Muscle Fiber
• Page 258/318
• Fast-twitch (white) fiber
– Contract most rapidly, forcefully
– Fatigue quickly due to lactic acid build-up
– Anaerobic b/c they do not need a lot of O2
• Slow-twitch (red) fiber
– Contract more slowly, less intensely
• (ex. Muscles that maintain posture)
• Intermediate fibers
– Combine red and white qualities

16
Muscle Fatigue
• Muscle Fatigue is the state of exhaustion
produced by strenuous muscular activity
• Physiologic or psychologic?
• Low levels of ATP cause physiologic MF
• Complete physiologic MF rarely occurs b/c
psychological fatigue is what produces the
exhausted feeling that stops us from
continuing

Connective Tissue and Muscle
• Fascia
– Involved in nearly all
the fundamental
processes of
the body
– Intimately related to
muscle

19
Myofascial Integration: Tensegrity
• Sheets and lines of fascia create a whole-body
network.
• Tensegrity: balance of tensile forces
– Shows resiliency, becoming more stabile as the
load increases
• Full-body massage addresses the tensegric
nature of the body
• Localized work is directed at the symptom not
the cause and is therefore less effective

Pathologic Connective
Tissue Changes
• Over time, connective tissue
–
–
–
–
Thickens
Shortens
Calcifies
Erodes
• Changes can come from sudden or sustained
forces
• Ground substance and collagen combine and
can cause dysfunction  overworked and
undernourished muscle  trigger point pain

21
Muscle Attachment
• Direct attachments (rare)
– Muscles attach to bone or
cartilage
• Indirect attachments (more
common)
– Muscle fascia extends
beyond muscle
– Attaches to other connective
tissue

Functions and Naming
• Name of muscle in specific action depends
on function:
–
–
–
–
–
–
Mover (agonist)
Antagonist
Fixator (stabilizer)
Neutralizer
Support muscle
Synergist
27

27
Receptors
• Provide information to central nervous system
– Muscle spindles: respond to sudden, prolonged
stretch
– Tendon organs: respond to tension in muscle
relayed to tendon
– Joint kinesthetic receptors: respond to pressure,
changes in joint movement
Reflexes are automatic responses triggered by
change in the environment

Lesson 9.7 Objective
• Apply knowledge of the muscular system to
therapeutic massage application.
171
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
171
Mechanisms of Disease, I
• Causal factors increase muscle tension
• Tension leads to localized ischemia and
edema
• Pain results
• Pain leads to spasm; spasm increases pain
• Inflammation or chronic irritation may result
• Stations in tense tissue report to CNS, which
leads to hyperactivity
172
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
172
Mechanisms of Disease, II
• Macrophages and fibroblasts are activated
• Connective tissue production increases
• Distortions in one area could create
distortions elsewhere
• Chronic hypertension and fibrotic changes
may occur
• Chain reactions occur in myotatic units
• Sustained tension results in ischemia in
tendinous areas
173
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
173
Mechanisms of Disease, III
• Abnormal biomechanics and bodywide
compensatory patterns develop
• Joint restriction and imbalance may occur
• Trigger points develop
• Generalized fatigue develops
• Sympathetic arousal is heightened
• Immune response is inhibited
• Massage intervention and medication can
help
174

174
Medications
• Antibiotics
– Treat bacterial infections
• Steroids and NSAID (non-steroidal antiinflammatory drugs)
– Help ease inflammation
• Muscle Relaxants
– Sooth spasms and hypertonic muscles
• Analgesics
– Pain relievers
• Antidepressants
– Help restore sleep
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
175
Medications
• Any medication, prescribed, over the counter,
or herbal or homeopathic remedies have an
effect on the client and therefore must be
taken into consideration when developing a
treatment plan
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
176
Specific Disorders, I
• Carpal tunnel syndrome
– Irritation of the median nerve as it passes through the transverse
carpal lig.
• Pain, tingling, numbness, weakness
• Thoracic outlet syndrome
– Impingement of the brachial plexus and blood supply of the arm
• Shooting pain, weakness, numbness, discoloration of the arm can also
occur
• Stress-induced muscle tension and headache
– Contraction of the muscles puts pressure on the nerves
• Dull, persistent ache, with a feeling of tightness
• Muscle strain
– Overstretching or tearing of muscle fibers
• Repair takes weeks and some muscle fibers may be replaced with fibrous
tissue
177
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
177
Specific Disorders, II
• Contusion
– Bruise or bleeding under the skin, inflammation
– Crush injury can result in myoglobin in the blood causing
kidney failure
• Muscle infections
– Bacterial, viral, parasitic
• Often produces local or widespread myositis
• Poliomyelitis
– Viral infection of the nerves affecting the musculoskeletal
sys.
• Myositis ossificans
– Inflammation process that produces osseous tissue in the
fascicles of muscle.
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
178
Specific Disorders, III
• Tendonitis and tenosynovitis
– Inflammation of tendon/tendon sheath
• Caused by trauma or overuse, or systemic inflammatory
disease (e.g. RA)
• Cramps/spasms
– Painful muscle spasms or involuntary twitches
• Flaccidity and spasticity
– Muscle with decreased tone vs. excessive tone
• Contracture
– Chronic shortening of a muscle
179
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
179
Specific Disorders, IV
• Muscular dystrophy
– Atrophy of skeletal muscle with no mal-function of the nervous
sys.
• Amyotrophic lateral sclerosis
– Lou Gehrig’s Disease, characterized by tripping, stumbling, and
falling; loss of muscle control and strength in hands and arms;
difficulty speaking, swallowing or breathing; chronic fatigue,
muscle twitching or cramps
• Myasthenia gravis
– Autoimmune disease in which the immune sys. Attacks the
muscle cells at neuromuscular junctions affecting ACH, therefore
nerve impulses are unable to stimulate the muscle fully
• Hernia
– Protrusion of an abdominal organ through the muscular wall
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
180
Specific Disorders, V
• Torticollis
– spasm or shortening of SCM
• Whiplash
– sudden hyperextension or flexion causing damage to soft
tissue of the neck
• Dupuytren’s contracture
• Rotator cuff tear
– Overuse or impingement may weaken the muscles of the
rotator cuff can cause partial or complete tears
– Weakness, atrophy, pain or tenderness may occur
Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved.
181
Specific Disorders, VI
• Shin splints
– Inflammation or tearing of the muscle from the tibia, usually tibialis
anterior, can also result in stress fractures
• Anterior compartment syndrome
– Any condition that increases pressure in the compartment of the leg can
cut off blood supply and nerve function
– Overuse, repetitive stress and accelerated growth are common factors
• Plantar fasciitis
– Inflammation and slight tearing of the plantar fascia
– Caused by excessive stress to the foot commonly near the attachment to
the clacaneus (stress causes calcium deposits, which can cause bone
spurs)
• Fibromyalgia
– Aching, fatigue, stiffness, sleep disruption, multiple tender points,
headaches, irritable bladder, dysmenorrhea, cold sensitivity, restless leg,
Raynaud’s Phenomenon, numbness, tingling, and weakness
• Acquired metabolic and toxic myopathies
– Nutritional and vitamin deficiency, especially protein and vitamin C, D. E,
may lead to myopathy
Massage and Inflammation
• Acute phase (first 72 hours) massage is
usually contraindicated
• RICE
• Chronic massage is usually indicated
• If massage could increase the inflammatory
response it is contraindicated
