Q

What does traction do?

A
  • Used to alleviate pressure on structures such as nerves or joints that produce pain or
    other sensory changes or that become
    inflamed when compressed

Q

How does the treatment of wounds and TB compare from years ago to today…

A

Years ago….
IR lamps were commonly used to treat
wounds because it dried out the wound
Sunlight was used to treat tuberculosis

Today….
We know that wounds heal faster when kept
moist
Antibiotics are more effective in treating
tuberculosis

Q

The Role of Physical Agents in

Rehabilitation

A
– “Without documentation which 
justifies the necessity of the 
exclusive use of physical 
agents/modalities, the use of physical 
agents/modalities, in the absence of 
other skilled therapeutic or 
educational intervention, should not 
be considered physical therapy.”

A

is “the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.”

• Defined as an unpleasant sensory and
emotional experience associated with actual or potential tissue damage or described in terms of such damage
• Usually acts as a warning to protect the body from damage
• Most common symptom prompting patients
to seek medical attention
• Many patients with musculoskeletal or Many patients with musculoskeletal or neurological impairments report pain
• Primary goal either control or relief of pain

62
Q

ting g lin

67
Q

How does acute pain affect other systems of the body?

A
• Systemic Level
• “fight or flight”
• Increased heart rate Increased heart rate
• Increased sweating
• Expansion of the bronchioles
• Dilation of pupils
• Shunting of blood from skin and digestive tract 
to the muscles and brain
68
Q

Talk about circulation and muscle complications associated with pain

A

• Compromised circulation is often
inadequate to supply metabolic needs
leading to ischemia, a new source of pain
• Muscle guarding occurs (this reaction of
muscles requires a high level of metabolic
activity at the same time as it compresses
the blood vessels)
Comprised circulation impedes the removal
of the metabolic wastes, many of which
sensitize nocicep, g tors, resulting in further
enhancement of pain
• Edema resulting from injury causes
disruption of the capillaries and lymphatics,
with an increase in capillary permeability as
a result of compression from muscle
guarding
• Further compounds the problems of nutrient
supply and waste removal, causing
additional pain perception and subsequent
muscl di e guarding
• Vicious circle of pain, spasm and pain
• Pain producing substances are released

69
Q

Define Chronic paint

• Defined as pain that does not resolve in the
usual time it takes for the disorder to heal or
that continues beyond the duration of
noxious stimulation
• Time-based definitions
• Pain lasting longer than 3 or 6 months
• Ongoing condition that is difficult to
manage

Q

What is fibromyalgia?

A

High concentration of “Substance P” in muscles

• Patients with prolonged severe, or very
disabling acute pain have been found to be at increased risk of developg p in chronic pain.
• Pain that lasts longer than 3 months and
leads to a long-term loss of function, as well as imposing many psychosocial stresses on the patient and his or her friends and family.

80
Q

not been well defined.
• If pain meets the following three criteria it If pain meets the following three criteria, it
is usually termed chronic pain:

81
Q

What is referred pain? How does it work?

A
  • Maybe acute or chronic
  • Pain felt at a site in the body elsewhere from the source of disease or injury from the source of disease or injury.
  • Referred from one joint to another (hip joint pathology may refer pain to knee).
  • Peripheral nerve to a distal area of innervation (compression of spinal nerve).
  • Internal organ to an area of musculosketal Internal organ to an area of musculosketaltissue. (angina-upper chest,arm)
  • Gallbladder frequently refers pain to the right shoulder or inferior angle of the right scapula.
82

A

Important to be aware when treating a neuromusculoskeletal dysfunction, that there is potential for pain referral and be familiar with common pain referral patterns in order to determine the source of a patient’s complaints and select appropriate treatment methods.

83
Q

Mechanisms of Pain Reception and Transmission

A
  • Pain is generally felt in response to stimulation of peripheral nociceptive structures
  • Stimulus is transmitted along peripheral nerves to the CNS
  • Reach the cortex and consciousness
84
Q

Sensation of pain and the response to the sensation are influenced by a variety of factors, which are…

A

• Physiological mechanisms of the pain receptors
• Anatomy of pain transmitting structures
• Neurotransmitter levels
• Motivation, behavior and physiological and
emotional state of the individual

Variations in any of these factors can alter the individual’s perception of pain severity, type, location and duration

85
Q

GATE CONTROL THEORY..

A

• Gate theory briefly states that as nerve
fibers transmit pain impulses through the
sp ,yy inal cord to the brain, they may be altered
or modified presynaptically at any point
along the transmission route from the spinal
cord to the cerebral cortex.

86
Q

ENDORPHIN THEORY…

A

• Endorphins/enkephalins (body’s own natural pain relievers) of the nervous system are released in response to the stimulation of the nervous system, particularly via
electrical stimulation.

87
Q

How do you measure pain?

A
  • Visual analog and numeric scales.
  • Comparison with a predefined stimulus
  • Semantic differential scales.
88
Q

What is a semantic differential pain scale?

A

e.g. - select words that describe your pain. What does your pain feel like?
• Please select the word(s) that best describes your present experience of pain.

Should be used for detailed desciption

89
Q

What is a visual analog or numeric scale?

A

Indicate the present level of pain on a drawn line or rate the pain numerically on a scale of 1 to 10

Also could include face scale

90
