Lymphatic care glossary

Brief definitions of 40 terms used in the Resource Centre. For assessment and treatment decisions, follow the linked guides for context.

A–C

Adjustable compression wrap

A reusable compression item with adjustable overlapping straps. It requires appropriate sizing, fit, and instructions for use.1

Lymphedema associated with cancer or treatment affecting lymph nodes, vessels, or nearby tissue.2 Read the guide.

Cellulitis

A bacterial infection of skin and deeper tissue. Increasing warmth, redness, pain, swelling, fever, or feeling unwell needs prompt medical assessment.3

Certification

A credential awarded after meeting a school’s or certifying organization’s requirements. It is distinct from registration in a regulated profession.4

Clinical guideline

Recommendations for a defined health topic and population. Their value depends on the evidence and methods used to develop them.

Complete decongestive therapy (CDT)

A coordinated lymphedema management approach combining compression, skin care, movement, education, self-management, and selected manual techniques. It often includes reduction and maintenance phases.15

Compression bandaging

Layers of bandages applied to help manage swelling. Appropriate assessment, application, and follow-up are important; incorrect bandaging can be harmful.16

Compression garment

A fitted sleeve, stocking, glove, or similar item that applies external pressure. Construction, pressure, and fit are selected for the purpose and person.12

Conflict of interest

A financial, professional, or other interest that could influence judgement. Disclosure helps readers assess its relevance.7

Consensus statement

A document recording expert agreement on a subject, often where research is incomplete or practice varies. It is not equivalent to a systematic review.1

Conservative care

Non-surgical management, such as compression, movement, skin care, education, or symptom treatment.18

D–G

Deep vein thrombosis (DVT)

A clot in a deep vein. New one-sided swelling with pain, warmth, or tenderness needs prompt assessment. A clot can travel to the lungs; call 911 for sudden shortness of breath, chest pain, coughing up blood, or fainting.9

Decongestive lymphatic therapy (DLT)

A term for multi-part lymphedema care that overlaps with CDT. Components commonly include compression, drainage, skin care, exercise, and self-management.6

Directory listing

An entry in a provider or service directory. Inclusion criteria vary; a listing is not proof of registration, suitability, or insurance coverage.4

Edema

Swelling from fluid collecting in tissues. Lymphatic problems are one of several possible causes.1

Evidence certainty

Confidence in a research estimate, considering bias, consistency, precision, applicability, and missing evidence.10

Extended health insurance

Private or employer-sponsored coverage for specified health expenses. Eligible providers, products, and reimbursement limits depend on the policy.11

Fibrosis

Thickening or hardening associated with increased fibrous connective tissue. It can occur with longstanding lymphedema and other conditions.1

Generalizability

How well research findings apply beyond the population and setting studied. Also called applicability.

L

Lipedema

A chronic condition involving disproportionate fatty tissue, usually in the legs and sometimes arms, with possible pain, tenderness, and easy bruising.812 Read the guide.

Lymph

Fluid collected from tissues and carried through lymphatic vessels. Its contents vary with the region and circumstances.1

Lymph nodes

Small immune structures along lymphatic routes that receive lymph from nearby tissues and support immune responses.2

Lymph Drainage Therapy (LDT)

The Chikly Health Institute’s name for its manual-therapy training approach. It is distinct from decongestive lymphatic therapy.13

Lymphatic system

A network that returns fluid and proteins to the bloodstream and contributes to immune function.1 How it works.

Lymphedema

Swelling and tissue changes associated with impaired lymph transport. It can involve limbs, the trunk, genitals, or head and neck.12 Read the guide.

M–P

Manual lymphatic drainage (MLD)

A technique using light, directed movements on the skin. It may form part of a broader lymphedema management plan.12

Mechanism

An explanation of how a treatment might work. A plausible mechanism does not by itself establish a benefit in patients.14

Outcome

A measure used to assess change, such as swelling, pain, movement, daily function, or quality of life.

Pitting

A temporary dent left by pressure on swollen tissue. It can occur with several causes of edema and does not establish a diagnosis.1

Pneumatic compression device

A pump and inflatable garment that apply pressure in a programmed sequence. Suitability, settings, and monitoring require individual guidance.12

Primary lymphedema

Lymphedema related to developmental or genetic differences in the lymphatic system. It can first appear at different ages.1

Publicly funded health care

Services paid through provincial, territorial, or other public programs, each with its own coverage and eligibility rules.15

Q–S

Quality of life

How health affects the parts of life that matter to a person, including comfort, activity, relationships, and emotional wellbeing.

Randomized controlled trial (RCT)

A study assigning participants to comparison groups by chance. Reliability still depends on methods, sample size, follow-up, and other sources of bias.14

Referral

A request or recommendation for assessment or care by another professional or service. It does not guarantee coverage or an appointment.

Regulated health profession

A profession governed by law and a regulatory body in a province or territory, with requirements for practice, titles, and accountability.416

Registration or licensure

Formal status permitting practice or use of a protected professional title under a jurisdiction’s rules. Current status can be checked with the regulator.416

Secondary lymphedema

Lymphedema following an acquired change, such as surgery, radiation, injury, infection, or another disease process.1

Self-management

Skills and routines used between appointments, such as skin care, movement, compression, and individually taught techniques.56

Systematic review

A review using planned methods to find, assess, and combine research on a defined question. Its conclusions depend on both the review methods and the available studies.10
