Q

T/F

STT is commonly used in clinical settings because of its selectivity when placing tissues under tension

A

It is very difficult to be “selective” when placing tissues under tension
Joint positioning affects multiple structures
Muscle contractions CANNOT occur in isolation

Q

Explain the traumatic hyperemia effect of DF

A

↑ blood circulation & lymph flow

  • Help with removal of chemical irritant by-products of inflammation
  • ↓ venous congestion → ↓ edema & hydrostatic pressure on pain-sensitive structure

Q

Explain the pain relief effect of DF

A

Stimulates type I & II mechanoreceptors producing presynaptic anesthesia

Based on the Gate control theory of pain

Acute phase: if done too vigorously would cancel this effect & ↑ pain by too much stimulation of nociceptors

Q

T/F

Decreasing scar tissue & adhesions is an effect obtained with light DTF in all phases of the healing process.

A

Light DTF is suggested in the the inflammatory phase and early prolif phase

In Late proliferative & remodeling phases: not precised

16
Q

Explain the Decreasing scar tissue & adhesions effect of DTF in the inflammatory and early proliferative phase

A

Inflammatory and early proliferative phases
- Light DTF only
Rationale:
- To minimize the cross-linking & enhance the extensibility of the new tissue
- To prevent adhesion formation
- To maintain mobility between tissues

17
Q

Explain the Decreasing scar tissue & adhesions effect of DTF in Late proliferative & remodeling phases

A

Late proliferative & remodeling phases
- Assists with the orientation of the collagen in the appropriate lines of stress
- Breakdown of adhesions
(due to transverse nature of the frictions)

18
Q 
T/F
DF is indicated for:
1- Chronic lesions in the joints 
2- Acute injuries to ligament
3- Bursitis 
4- Acute inflammation (with acute swelling) 
5- subacute injuries to tendon 
6- before a strong stretch 
7- Adhesions between tissues
8- Hematomas or bruising
9- ↓ sensation or hypersensitivity (Light DF only)
10- Signs of infection
11 - Debilitated or open skin
12. ectopic ossification
13. cancer
14 - Pt have DVT but in an other area then the one treated
A 
1- Chronic lesions in the joints - T
2- Acute injuries to ligament - T
3- Bursitis - F
4- Acute inflammation (with acute swelling) - F
5- subacute injuries to tendon - T
6- before a strong stretch - T
7- Adhesions between tissues - T
8- Hematomas or bruising - F
9- ↓ sensation or hypersensitivity (Light DF only) - F
10- Signs of infection - F
11 - Debilitated or open skin - F
12. ectopic ossification- F
13. cancer - F
14 - Pt have DVT but in an other area then the one treated - T
19
Q

How do you position for DTF the tissue if it’s

  1. Td with no sheath and lig.
  2. Td with sheath
  3. Ms belly
A
  1. Td with no sheath and lig.: Moderate pain free stretch vs relaxed vs optimal tissue exposure position
  2. Td with sheath: Stretched
  3. Ms belly: Relaxed
20
Q

There is mistakes in the first steps of the application of this DTF technique, find them!

  • Use of lubricant or a hypoallergenic cream
  • Done perpendicular, parallel or circular to the orientation of the tissue fibres
  • Moves over the pt skin with the clinician’s finger over the site of the identified lesion with a circular motion
A
  • No use of lubricant
  • Done perpendicular to the orientation of the tissue fibres
  • Moves the pt skin with the clinician’s finger over the site of the identified lesion back & forth
    Blisters prevention: important to moves skin with fingers
21
Q

In the DTF application technique, what amount of pressure is ideal?

A

Amount of tension/pressure

  • Depend on the stage of healing
  • Begin with light pressure and build up to the target pressure
  • Need to reach the target tissue
22
Q

In the DTF application technique, what amplitude is ideal?

A

Sufficient to cover all of the affected tissue

23
Q

In the DTF application technique, what rate of application is ideal?

A

2-3 cycles/sec applied in a rhythmical manner

24
Q

Decribe the treatement duration for DTF

  • for general guidelines
  • for chronic lesions
  • for remodelling phase
A

Generally stop when desensitization occurs*

  • Usually takes 3-5 min
  • If doesn’t occur within that time frame stop DTF

For Chronic lesions / Remodeling phase

  • Continue for another 5 min after the desensitization period
  • To enhance the mechanical effect on adhesions & scar tissue
25
Q

T/F
After application of DTF
1. Involved tissue is passively stretched
2. Involved tissue is actively exercised
3. Be careful not to cause pain with ex’s
4. Apply ice in acute conditions in the clinic and at home

A

All true

26
Q

What should be the DTF frequency?

A

When the excess tenderness has worn off

Takes generally 2-7 days

27
Q

T/F about the total number of treatment with DTF

  1. The guidelines suggests 12 sessions for chronic patients
  2. Most conditions should resolve within 10-15 sessions over 8-12 wks
  3. If no tissue improvement after 5 sessions, Discontinue DTF
A
  1. F -> Pt specific → until no further improvements
  2. F -> Most conditions should resolve within 6-10 sessions over 2-8 wks
  3. If no tissue improvement after 3 session, Discontinue DTF
28
Q

A patient is complaining of exacerbation of symptoms after the 3rd session of DTF

What do you tell him/her?
A. It's normal
B. It's abnormal, we need to stop DTF
C. No pain no gain
D. May the force be with you

Explain your choice

A

DTF May exacerbate Sx following the 1st 2-3 sessions

Need to determine if the ↑ in pain is acceptable considering pt’s condition and phase of healing

Educate pt about it & ice application
