"Mobility of Elderly Patients When Using the l'Ergonome Mobility Device"

"The patient is positioned on a Winncare type bed dressed with a pressure-sensor sheet and equipped with either a hanging triangle bar (supporting arm of the bar is adjusted to 30 degrees) or an ERGONOME device according to randomization.~The patient is first installed on the bed in a strictly supine position, the pelvis centered, and the greater trochanter over the fold of the backrest.~The investigator then gives instructions on how to use the randomized device (correct hand placement).~The patient is asked to sit up twice (two consecutive attempts). The first attempt is a learning attempt. The observations necessary for this study will be taken on the second attempt. Thus the second sitting attempt is timed, video-taped and recorded via the pressure-sensor sheet beneath the patient."
