DP-Tx™ vs Compression: Understanding the Real Difference in Lymphoedema Care

For people living with lymphoedema, swelling, discomfort, and heaviness can make daily life more challenging than it needs to be. Compression bandaging and garments remain a core component of treatment, particularly during the intensive swelling reduction phase.

But new innovations, such as the DP-Tx™ Bra Insert, use differential pressure in a completely different way to support lymph flow, comfort, and long-term symptom management.

Understanding how these approaches differ is essential for patients and clinicians looking for safe, sustainable, long-term management tools.

Compression vs Differential Pressure: Two Very Different Mechanisms

How Compression Works

Compression garments and bandages apply sustained external force to the tissue. By applying graded pressure, the intention is to push excess lymph fluid away from the swollen area and prevent it from re-accumulating. They rely on:

• Graduated compression to force fluid away from swollen tissue

• High levels of constant pressure over hours or days

• Correct application, often requiring clinical skill

Compression is widely used and can be very effective, particularly during the intensive reduction phase of treatment.

However, research and clinical commentary do highlight several considerations with long-term, high compression:

• Prolonged strong compression can mechanically stress the superficial lymphatic capillaries, which are extremely delicate (only one cell thick).

• If compression is too high or poorly fitted, it may impede—not support—lymphatic pumping.

• Incorrect application can shift fluid laterally, causing swelling above or below the compressed region.

Supportive reference: ‘The International Lymphoedema Framework (ILF) notes that excessive or incorrectly applied compression may “restrict lymphatic refill” and stresses the importance of low, physiologically appropriate pressures.’

How DP-Tx™ Differential Pressure Works (Not Compression)

DP-Tx™ wearable inserts use a completely different principle. Instead of relying on constant force, they create gentle, shifting micro-pressures that assist flow without squeezing or flattening the lymphatic vessels.

DP-Tx™ works by:

• Creating soft, raised textiles that contact the skin through micro-points

• Generating subtle pressure changes with normal body movement and breathing

• Producing a massage-like, undulating action that helps break up stagnant fluid

• Supporting natural lymphatic contractions (lymphangion pumping) without relying on muscle activation

• Avoiding constant high compression on fragile vessels

This means DP-Tx™ provides an active, comfort-driven mechanism - not a compressive one.

How This Differs from ‘Pressure Differential’ Claims Elsewhere

Some textured products (e.g., block-based foams) are often described as creating a “pressure differential.”However, these devices require strong external compression to create any meaningful change in pressure zones. Without compression, the blocks remain static.

DP-Tx™ is fundamentally different:

It creates differential pressure independently of compression, activating with natural movement, breathing and posture changes — even under light garment tension. This makes it gentler, safer for long wear, and suitable for people who cannot tolerate compression or who need ongoing daily management.

Key Benefits of DP-Tx™ Differential Pressure Wearables

1. Exceptional Comfort for Long Wear

Compression garments can feel tight, hot and restrictive. DP-Tx™ wearables are made from soft, breathable materials designed for daily comfort. Many users describe the DP-Tx™ Bra Insert as “unnoticeable,” allowing them to wear it for longer periods, supporting more consistent symptom management.

2. Restored Confidence Through Discretion

The DP-Tx™ Bra Insert sits discreetly inside a standard or mastectomy bra, with no visual signs of medical garments or bandaging. Patients can wear their usual clothing comfortably, helping to restore normalcy and confidence.

3. Easy, Independent Self-Management

Compression bandaging requires skill, time, and often assistance. DP-Tx™ wearables are designed for:

• simple application

• independent daily use

• washability and reusability

• long-term durability

This supports a patient’s autonomy and reduces the burden of daily management.

Where DP-Tx™ Fits in the Lymphoedema Journey

Compression has an important role, particularly during the intensive reduction phase of severe swelling.

But for the ongoing maintenance phase, DP-Tx™ offers:

• a gentler alternative

• a more comfortable long-term option

• no risk of excessive compression

• a mechanism aligned with natural lymphatic physiology

• greater discretion and ease of use

By avoiding the potential risks associated with constant compression, while providing comfort, discretion and ease of use, DP-Tx™ represents an important step forward in supporting those living with lymphoedema.

Patients should always consult their lymphoedema specialist to determine the most appropriate combination of therapies.
