EXPLORESilcare Breathe Cushion Liner

Silcare Breathe Cushion Liner

PDAC Approved
Activity Level 3 (4)

Optimal control of a prosthetic limb depends on a comfortable and secure connection between limb and socket. Modern liner technology provides excellent cushioning, but the impermeable and insulating materials can allow a build-up of heat and moisture so they begin to slip and chafe. Air, perspiration and unnecessary movement can cause a loss of connection, compromised stability and damage to residual skin, potentially affecting mobility, safety and independence.

The patented technology of Silcare Breathe works by letting the air and perspiration that are often trapped between the liner and skin to escape through specially designed laser drilled perforations.  The air and moisture are then expelled from the socket as the wearer walks, resulting in drier skin and a healthier environment for the residual limb.  This helps to increase comfort and control, and reduce the damaging effects of relative motion on damp tissues that is often encountered with standard prosthetic liners.

Key Benefits

Laser Perforations

Optimally sized pores distributed uniformly along the length and distal end of the liner permit the escape of moisture. Use with a one-way valve on the socket helps to generate a better vacuum and more secure fit.

Stretch Zones

Seamless knitting technology provides bi-directional stretch to improve comfort and contouring  and reduce shear force on the knee as it flexes.

TendresseTM Finish

Provides a lower coefficient of friction than standard silicone, reducing shear stresses on the skin.

Silcare Breathe Technology

The body cools by moving blood flow closer to the surface of the skin, and when this is not sufficient the body produces sweat to increase cooling by evaporation.

The need to regulate body temperature is greater for amputees, and a lack of temperature regulation can have severe negative effects.

Benefits of breathable liner technology

The Silcare Breathe range has been designed to tackle these issues. Laser drilled perforations transmit moisture away from the skin to ensure a comfortable, cool and secure fit for the user.

  • Reduced relative movement between the residual limb and liner
  • Enhanced proprioception
  • Enhanced comfort
  • Drier, cooler, healthier skin

Testimonials

Steve

“I literally called it the ‘Holy grail’ as it’s been a product that I had been waiting for since becoming an amputee 8 years ago!”

“If you’re an active amputee that has struggled with the build-up of sweat in your liner, I would recommend this product.”

Charlie

“I normally have to stop several times to empty my liner and dry off my stump throughout the race.”

“The Silcare Breathe Liner is a fantastic product, it’s great for taking the sweat away which adds to that confidence and security.”

Dennis

“It’s the best product out there, I can’t see anything out there that compares to the way it works.”

“Due to the perforated holes in the liner, it draws moisture away from my limb while I’m walking and is much more comfortable without the skin breakdown”.

Adrian

“Silcare Breathe makes a huge difference – I can walk around without having to take my leg off to dry my limb.”

“It’s much more secure, and feels much better. Using the Liner I don’t have to think so much about what I’m doing and I can just get on with enjoying the things that I love.”

Cassie

“The very first time I used Silcare I was really surprised how dry and secure I was in it. When I’m running I’m held in the socket and a lot more stable”

Clinical Evidence

Researchers at Blatchford in the US and UK have recently published a report evaluating the outcomes of three patients with residual limb skin problems, when they switched from their previous prescriptions to perforated Silcare Breathe liners.

All of the cases experienced a substantial reduction in sweating on their residual limb and their skin problems resolve – some in as little as three months. The improved environment within the prosthetic socket allowed them to wear their limbs unaffected by the issues that had previously caused them to restrict activities and prosthetic limb use.

Silcare Breathe Cushion Liner Clinical Evidence Reference

Clinical Outcomes using Sweat Management liners

  • Improvements in residual limb health problems and wound healing1,2
  • Fewer residual skin issues2
  • Reduction in pain in residual and phantom limb2
  • Improved heat dissipation compared to other temperature regulation solutions3
  • Removes sweat from skin interface1,2,4
  • Perforations do not damage the skin4
  • Patients reported a preference for their perforated liners1,4
  • Reduces the need to remove prosthesis throughout the day to dry residual limb4

There are two published literature reviews that discuss different aspects of lower limb prosthetic liner technology5,6.

  • The main purpose of prosthetic liners is to cushion the transfer of loads from the prosthetic socket to the residual limb5.
  • Based on load-displacement data from the compressive stiffness tests, silicone was one of three materials that were recommended for situations where it is desirable for the liner to maintain thickness and volume since these materials had the least non-recovered strain5,7.
  • Under cyclic compressive loading, silicone was one of two materials that had the greatest cycles to failure under compressive loading, while the Pedilin and polyurethane samples lasted orders of magnitude less5,8.
  • Prosthetic liners and sockets are highly resistive to heat conduction and could be a major contributor to elevated skin temperatures5,9.
  • There are reduced residual limb pressures with the silicone liner compared to other conditions (no liner; soft inserts) suggesting that silicone has an ability to distribute pressure evenly to the residual limb4,10.
  • In terms of patient outcomes, there was no clear preference between silicone and Pelite liners5,11.
