Elderly care department students were randomized to the PK presentation technique (intervention group) and traditional PowerPoint presentations only (control group). The sample of the study consisted of 54 (intervention group = 28, control group = 26) elderly care department students. Data was collected using the Sociodemographic Form and the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI). PUPKAI was administered before the presentations (pre-test), after the presentations (post-test 1), and 4 weeks after the presentations (post-test 2).\u0000\u0000\u0000RESULTS\u0000Following the presentations, the intervention group's PUPKAI mean score (47.23 ± 11.62) was significantly higher than the control group's mean score (36.64 ± 12.41) (P < .05).

The IP at the time of application was measured on the right lower limb of 10 healthy volunteers at 2 different points (B1, C). Measurements were made in 2 positions, supine and standing. There were 2 consecutive applications and measurements made for each compression bandage set.
