No results posted yet for this study

Summary

The main objective of this study is to evaluate the relationship between the angle of knee flexion in a supine position with joint relaxation (DDPD) and the maximum interface pressure at the heel area (PtAl).

Conditions

  • Adult, Hospitalized

Interventions

OTHER

Knee flexion measurement 1

The angle of knee flexion during resting, supine position is measured by a first person.

OTHER

Knee flexion measurement 2

The angle of knee flexion during resting, supine position is measured by a second person.

OTHER

Heel - interface pressure measurements

The pressure analysis system used is the X Sensor X3 model (Xsensor Technology Corporation, Calgary, Canada). The sensor mat is made up of transducer cells, each measuring 1.6 cm\^2. The digital signal is transmitted to a PC via a USB port at a sampling frequency of 10Hz. Before each measurement, the sensor mat is calibrated from 10 to 220 mm Hg, according to the manufacturer's recommendations. The sheet of pressure sensors is disposed on the dedicated bed. The patient is then asked to take his/her usual position in the supine position and a latency of 5 minutes is observed. The recording time pressure is then performed for 90 seconds in the optical observing time to adapt to changes in media.
