14
Q
General Instructions
A
Intro to pt, explain, and demonstrate
Have pt perform AROM and observe for substitutions
Place pt in recommended test position (if they can’t perform AROM through full range, reposition pt in gravity-eliminated position)
Expose muscle and jt
Optimize body mechanics and stabilize proximal components as necessary
Encourage max effort and apply graded resistance
Check pt status
Record MMT grade
15
Q
Break Test
A
After segment has completed its range, resistance is applied near distal end of segment to which muscle attaches
Pt is asked to hold and not allow tester to “break” hold w/ resistance
Commonly used
More objective than active resistive test
Functional muscle strength and fatigue difficult to assess using this method
16
Q
Active Resistive/Dynamic Testing

27
To Improve Reliability
Standardize position
Stabilization of proximal body parts
Using grading criteria
Use same examiner
28
Other Methods of Measuring Strength
Hand-held dynamometry - values vary w/
- Method of applying resistance (make vs. break test)
- Body position in relation to gravity
- Joint angle
- Lever arm
- Stabilization
- Examiner's strength
Isokinetic dynamometry - can also measure torque, work, endurance
29
Muscle Weakness
When finding muscle weakness, assess muscle length
Muscle is tight - usually strong
Muscle that is lengthened - harder to produce strength, weaker
30
Stretch Weakness
From muscles remaining in elongated condition, however, slight beyond neutral physiological rest positions but not beyond normal range of muscle length
31
Over-Stretch Weakness
From 2-jt or multi-jt muscles, weakness results from repetitive or habitual positions that elongate that muscles beyond normal range of muscle length

Interesting Facts about Pain
Most common reason ppl visit healthcare provides
LBP is second most common
Chronic pain affects more people than DM, heart disease, and cancer combined
Spinal pain, arthritis, and headaches - most common sources of pain
44
Pain Physiology
Noxius stimuli - mechanical, thermal and/or chemical (transduction or nociception)
Site of stimuli - spinal cord - brain stem - thalamus/cortex and higher levels of brain (transmission or pain cognition)
End result of activity - pain becomes conscious multidimensional experience (perception or suffering and pain behavior)
- Reticular system - action and asses
- Somatosensory cortex - identify signal and relate it to past
- Limbic system - emotions, behavior, processing
Signal can be changed or inhibited (modulation - send more inflammatory markers or signals to heighten pain)
45
Peripheral and Central Sensitization
Abnormal facilitation of descending modulation of pain
Peripheral - afferent nociceptive input increased (constant, persistent LBP - brain lengthens time, so there is heightened sensitivity, jumpy, tender) - occurs when there is inflammation of either peripheral tissues or neural connective tissue as protective mechanism
Central - increased excitability in dorsal horn and inflammatory chemical mediators up-regulate (occurs in fibromyalgia, myofascial pain syndrome, TMJ disorder, neuropathic pain) - constant, terminal illness, long term pain
Both can persist even when cause has removed
46
Gait Control Theory
Presynaptic inhibition of transmission cell - preventing pain stimuli from being transmitted to brain
W/ sufficient stimulus of nerve endings, "gate" can be closed (i.e. through massage, TENS, vibration)
Descending inhibition is possible at all levels of the nervous system and is opioid sensitive; however, can also be enhanced thru placebos, antidepressants, and anticonvulsants
47
Biomedical Model
Health = absence of disease
Every disease can be explained in terms of underlying problem
Focuses on physical and biological factors of disease
Diagnosis, treat, and cure
X-rays, blood work, surgery, chemotherapy, meds, hospitalization
48
Biopsychosocial Model
Absence of tissue damage/disease DOES NOT always = health (chronic pain)
Physiological and psychological components that are associated w/ chronic illness/pain
Suffering, pain behavior, chronic pain syndrome
Peripheral and central sensitization
49
Acute Pain
Associated w/ tissue damage or threat of damage
Resolves once healed or threat resolves
Physiological signs - sweating, pallor, nausea, HR or BP changes
50
Recurrent Pain
Repeated episodes of acute pain
51
Persistent Pain
Acute pain that continues when cause is not resolved
As long as disease remains, pain remains
Associated w/ chronic diseases such as OA or diabetic peripheral neuropathy
Pain proportional to tissue damage and nociceptive input
52
Chronic Pain
Pain that persists more than 3 months
Long lasting, persistent, and of sufficient duration and intensity to negatively affect a pt's well being, function, and QOL
Persists past healing phase w/ impairment greater than anticipated based on physical findings or injury and occurs in absence of observed tissue injury/damage
Treatment of such should address secondary pathology and perpetuating factors than focus on presumed initial insult/injury
53
Chronic Pain Syndrome
Doctor shopping
Dependency on health care system for multiple medial problems
Preoccupation w/ pain, significant pain behavior
Passive-dependent personality traits
Denial of emotional or family conflicts
Significant disruption in many areas
Feelings of isolation and loneliness
Being demanding, angry, or skeptical
Lack of insight into self-defeating behaviors
Use of pain as symbolic means of communication
54

64
Cyriax Concepts - Active Mvt
Specific soft tissue can't be incriminated
Provides into about pt's ability to move, painful range and possible location of originating pain
65
Cyriax Concepts - Passive Mvt
Tests inert structures (jt capsules, ligament bursa, fascia)
Provides gross assessment of length of extra-articular and periarticular soft tissue
66
Cyriax Concepts - Active vs. Passive Mvt
If both are restricted and/or painful in same direction, pattern is indicative of a capsular or arthrogenic lesion (capsular pattern - AROM is hard/painful, passive is limited and can't go further - something wrong in capsule - limited in same direction)
If active/passive actions are restricted and/or painful in opposite directions, it's indicative of contractile lesion
67
Cyriax Concepts - Resistive Motion
Isolation of contractile tissue (muscle, tendon, bony insertion) by isometric contraction in midrange of jt motion
Exceptions - fracture close to muscle insertion causing shifting of fractured ends OR inflamed structure underlying muscle
68
Cyriax Concepts - Resisted Isometric Testing
Strong and painless - WNL or referred pain from another area
Strong and painful - minor lesion of tested muscle or tendon
Weak and painless - disorder of NS or neuromuscular junction, total rupture of tested muscle/tendons, disuse atrophy
Weak and painful - major lesion such as fx and neoplasm, acute inflammation inhibiting muscle contraction, partial rupture of tested muscle or tendon

Type 3 - distraction - SLR (shooting pain down when lying down, but no pain when sitting and extending knee - positive)
Type 4 - regional disturbances - weakness/sensory (numbness, weakness, can't move limb
Type 5 - overreaction - exaggerated painful response to stimulus that is not reproduced when same stimulus is given later
