compared to two alternative silicone gel adhesive dressings

Aim: To assess whether the CHF dressings provided volunteers with a perception of
protection against forces such as knocks compared to an alternative silicone gel
adhesive (ASGA)* and bilaminate island silicone** (BIS) dressings.
Method: 74 Volunteers were blindfolded and had CHF and test dressings applied to
their elbows. Dressings were randomised. Subjects were given a metal rod to hold and
placed their elbows on the table. Subjects were asked to lower their arms forward over
the table and rate their perception of protection of the dressings. In-vitro testing of the
dispersion of external force by dressings was also conducted. Dressings were applied to
a pressure sensitive mat and force applied using a tensile tester. The average pressure
detected by the pressure mat was measured, and compared to pressure detected by the
pressure mat when no dressing was present.
Results: There was significance evidence that CHF was perceived by subjects to have
a greater level of protection than both ASGA (p
