Complete Decongestive Therapy Overview
Manual Lymph Drainage
- specialized soft tissue mobilization which stimulates lymphatic vessels
- approach is a systematic, mild manual stretching to facilitate flow to main lymphatic vessels. Excessive manual pressure and stretching can strain and damage affected lymphatic vessels.
- strokes are in the direction of lymph flow and/or toward intact lymph pathways
- strokes start proximally to clear the way for drainage from more distal areas
- stroke descriptions include:
Stationary Circles
|
W14 MLD Brief lab: 5:31 |
Common around neck and face, but can be applied in most regions |
Pumping |
W14 MLD Brief lab begin at 5:44; and begin 9:17 |
Performed on extremity; distal to proximal |
Scooping |
W14 MLD Brief lab 10:14 |
Performed on the distal end of the extremity |
Rotary |
W14 MLD Brief lab 7:23 |
used for more flat areas, like trunk and abdomen |
- pressure smoothly increases (working phase) and decreases (resting phase)
- Rx sessions typically last 40-90 minutes
- goals of MLD: increase lymphatic flow, increase extensibility of soft tissues, increase collateral lymph vessel formation
- frequency of treatment is 2-5x/week for 2-8 weeks until limb size stabilizes/plateaus
Value: 1
Value: 4
Intermittent Pneumatic Compression
- compressive sleeve is applied to limb; can be single chamber or multiple chamber
- chambers within sleeve are filled with air which provides distal-proximal external compression
- Treatment time, on/off cycle, and amount of pressure is set by the treating PT
- general guidelines are 30-60 mmHg for the UE, 40-80 mmHg for the LE
- extremity is positioned above the heart to facilitate fluid return and to decrease strain to venous system
- close monitoring of the patient for adverse reactions (numbness, tingling, increased edema above sleeve, changes in skin texture at base of sleeve
- contraindicated for patients with hx of nerve disease, abdominal or genital swelling, infection, renal disease/uncontrolled HTN, and/or DVT risk.
Compression Bandaging
- goals of bandaging are
- increase hydrostatic pressure within tissues (push fluid back in)
- increase absorption of fluid by veins
- increase absorption of protein by lymphatics
- principles of compression bandaging follows LaPlace's Law
- Sub-bandage pressure/compression (mmHg) =
- (tension x layers) ÷ (circumference of leg [cm] x width of bandage [cm])
- increase in leg circumference ==> decreased compression (mmHg)
- increase in bandage width ==> decreased compression (mmHg); bandage width typically increases from distal to proximal
- consistently applied tension in the bandage, from distal to proximal, will result in greatest compression at the smallest diameter (e.g., greatest compression is at the most distal/dependent component of the extremity
- bandages are selected which provide low resting, high working pressure (e.g., pressure increases when the limb is moving
- bandages are applied in layers for optimal external pressure
- bandage application approaches include figure-8 and concentric circles
- multiple types of materials are used in bandaging to protect skin and increase working pressure during compression (stockinette, short stretch, foam padding)
- excessive pressure should be avoided: monitor for numbness, tingling, increased swelling/indentation distal to bandage
- sufficient pressure should be applied so that bandage does not shift/move considerably during active movement

Compression Garments
- patients are measured for a compression garment once limb girth measurements are stabilized
- custom and off-the-shelf options are available
- reimbursement, patient compliance (comfort, esthetics, ability to donn/doff) directly influences garment selection
- lifespan of a garment is typically 3-4 months
Exercise
- light ROM exercises while compression is applied to facilitate lymphatic flow
- includes breathing exercises to stimulate proximal lymphatic channels
- movements are proximal to distal so lymph channels may open an allow for flow
Patient Education
- skin care, UV protection/sunburn prevention, monitoring for infection
- skin extensibility - low pH lotions
- patient/family training in self-massage, exercises, compression wrapping
- demonstration and practice donning/doffing garments
- light exercise activity for weight management; no heavy lifting with involved extremity and avoid heat/overheating with exercise
- avoiding tight jewelry or other constricting clothing
- prompt health care providers so compression/trauma from blood pressure/draws on affected side is avoided.
- wear gloves when working on activities where skin is at risk for tears/abrasions
