Q

Kinesio Tape Theory

A

KT is applied unstretched over manually stretched skin above the injured muscle to form convolutions which lift the skin
Convolutions facilitate the body’s natural healing process by increasing interstitial space resulting in decreased pressure and irritation on neural, sensory, and lymphatic structures which results in decreased pain, decreased swelling, and more free drainage of the lymphatic system

Q

Reasons to use Kineso Tape

A

Decreased muscle strength
- Facilitation muscle contraction
- Stabilize joint
- Promote active range of motion through spring assistance
Hypertonicity
- Inhibits muscle contraction
Muscle overuse or myalgia
- Promote recovery of inflammed, swollen or stiff muscles by increasing space between skin and muscle and promote flow of lymphatic tissue and decrease compression of pain receptors
Swelling/edema
- Tape is positioned to recoil and promote drainage toward healthy lymph node
- Increase space between skin and muscle to improve flow of lymphatic tissue
Pain
Reduce muscle fatigue
Scar tissue
Asymmetrical posture/movement
Sensory stimulation
Hypermobility
Hematoma/bruising

Accumulation of electrodes under elctrodes may lead to electrochemical skin irritation and burns under the negative electrode
Use lower level of current when treatment electrode is negative

Developed hypersensitivity that causes pain due to repetitive stimulation of afferent C-pain fibers
- Frequent stimulation results in stronger fiber memory
Presents with pain hypersensitivity, tactile allodynia (intense pain from innocuous stimuli), pressure hyperalgesia, limiting movement, and decreased performance and functional independence

53
Q

Sub-sensory level TENS (Microcurrent electrical neuromuscular stimulation (MENS) or sublimination stimulation)

A

Monophasic pulsed current intensity below threshold for nerve depolarization
Stimulation enhance cellular physiology and processes by moving ions in tissues at a low magnitude
Cutaneous sensation is not felt
Uses acupuncture points
Studies failed to demonstrate treatment is significantly more effective than placebo
Cranial electrotherapy stimulation
- Microcurrent, subthreshold
- Treats sleep disorders, depression, anxiety

54
Q

Sensory level TENS (Conventional or high rate TENS)

A

Activates cutaneous tactile sensory fibers resulting in cutaneous paresthesia or tingling sensation without eliciting any motor response
Uses gate control mechanism and opiate-mediated pain control theory to decrease pain
Frequency is from 50-150 Hz
Amplitude is increased until the patient feels tingling and buzzling at a comfortable level
Long term effects are limited to no longer than one hour

55
Q

Gate Control Theory of Pain

A

Pain stimuli is either allowed to pass or is blocked by a gate in the dorsal horn of the spinal cord
Anxiety, negative thoughts, poor past experiences, or depression can open the gate and increase perception of pain
Positive thoughts and relaxation can close the gate to decrease perception of pain

56
Q

Opioid Mediated Theory of Pain

A

Theory that endogenous opioids are pain-mediating chemicals that are produced in the body and affect the CNS and PNS

57
Q

Motor level TENS

A

High amplitude and low frequency
Amplitude: high enough to produce visible muscle contractions
Uses Gate control theory or opiate mediated pain control
Frequency: 1-4 Hertz (pps)
Pulse width: 150-250 microseconds
Intensity: increase until patient receives muscle contraction (30-60 miliamps)
Duration: 20-30 minutes once daily
Used for chronic pain
Goals is to selectively activate small diameter nerve fibers arising from muscles to induct a phasic muscle twitch
Avoid any joint movement contraindicated
Use for chronic pain, pain caused by damage to deep tissues, myofascial pain, and pain caused by muscle spasm

58
Q

Noxious level TENS

A

Frequency is greater than 100 Hertz (pps)
Pulse width: 300-1000 microseconds
Amplitude: increased until pain is perceived
Impulses release endogenous opiates and inhibit release of substance P
High level of analgesia achieved, but effects short-lived and transitory

59
Q

A-delta fibers

A

Myelinated pain fibers that carry sharp, well-localized pain signals

60
Q

C-fibers

A

Unmyelinated pain fibers that carry poorly localized burning and aching sensation and are easily injured

61
Q

Pain pathway

A

Afferent fibers
T-cells receive input from afferent fibers and assist in discriminating the type of pain
Brain
- Somatosensory cortex
-> Perceives pain as sharp, discriminative, localized to specific area
-> Is responsible for automatic reaction to pain
- Spinoreticulothalamic pathway
-> Terminates in thalamus/midbrain region
-> Perceives pain as diffuse, poorly localized somatic and visceral pain
- Frontal cortex
-> Defines perceptions and response to pain
-> Signals to release neurotransmitters which moderate and affect flow of afferent impulses
Descending inhibitory fibers in higher brain centers release neurotransmitters to affect flow of afferent impulses

62
Q

Interferrential current Therapy

A

High frequency (1-100Hz) carrier waveform penetrates the skin more deeply than a regular TENS unit with less discomfort
Deeper tissues cancel out the carrier waveform resulting in TENS like signal deeper under the skin

63
Q

Functional electrical stimulation

A

Uses pulsed current to stimulate peripheral nerves to allow clients to perform a functional activity
Ex. Wireless walking FES system helps with lifting leg or foot drop

64
Q

Analgesia from cold

Apply to body segment and secure
Start treatment timer for 20 minutes and advise to immediately indicate if hot pack feels to hot
At 5 minutes, check patient’s status and assess for burning, blistering, or excessive redness
- Briefly apply a cold pack if there is overheating
At the end of 20 minutes, remove towels and hot pack, check patient’s status, and check to see if treated area is slightly red and warm to touch
Place hot pack back in hydrocollator to reheat for 30-120 minutes

72
Q

Q

Contrast baths

A

Immersing extremity in alternating tubs of hot and cold water causes extremity to cycle between vasodilation and vasoconstriction

  • Extremity is held in hot water for 3 or 4 minutes (105-110 F) and then immediately immersed in cold water (50-60 F)

86
Q

Healing process

A

Typically takes 4 weeks
Inflammatory phase (time of injury - 7 days)
Proliferative phase (3 days - 3 weeks after injury)
Maturation/remodeling phase (2 weeks - 1 year or longer after injury)

87
Q

Inflammatory Phase

A

Lasts from time of injury - 7 days
Leukocytes, neutrophils, and monocytes are sent to the injured area to decontaminate the wound
Blood vessels dilate in response to histamine release to provide increased blood supply for healing
Blood flow to area causes the area to become red, hot, swollen, and painful
Edema surrounds wound to bind edges together
Associated with red/blue/purple skin color, heat, swelling, pain, and potentially some loss in function
If too much inflammation occurs, excessive scar is produced
Neovascularization
- New circulatory loops fill wound creating highly pink to reddish wound color
- Immobilization is essential during this phase to permit vascular regrowth and prevent new breakdown

88
Q

Proliferative phase

A

3 days - 3 weeks after injury
AKA epithelialization or granulation phase
Damaged area is filled with new connective tissue and covered with new epithelium
Granulation tissue fills in wound site, binding and protecting the area (granulation)
Epithelial cells migrate upward and repair the wounded area (epithelization)
Wound contraction results in decreased size of wound
Scabs form a temporary barrier and should not be disturbed

89
Q

Maturation/remodeling phase

A

2 weeks - 1 year or longer after injury
Continued fibroblastic activity and collagen synthesis and lysis lead development of a scar with maximum tensile strength
Scar formed is dense, disorganized, and may appear rosier
Scar formation occurs when collagen synthesis exceeds collagen lysis
Hypertrophic scars
- Scars within the boundaries of the lesion
Keloid scars
- Scars that extend beyond the boundary of the wound and appear raised

90
Q
