Understanding the Measurement of Girdle Dissociation in the Fall of the Older People Subject.

Study Overview
=================
Brief Summary
-----------------
Falls, especially in the older people, are frequent with potential serious consequences. The strategy for preventing falls involves detecting the fall risk. Current tests to determine the risk of falling are too late indicators of gait disorder. Loss of gait dissociation is an element associated with the mechanism of the fall and appears earlier. Its diagnosis is particularly important as it is a reversible impairment if rehabilitation interventions can be proposed to correct this anomaly.

Detailed Description
-----------------
The purpose of this study is to validate the device's measurement of belt dissociation in a discriminating manner between fallers and nonfallers.

Design Details

Primary Purpose: Prevention
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Case-control study from the clinical gerontology service and the PROOF cohort. Cases: patients who fell (= at least one fall in the last 12 months) mainly from the clinical from the clinical gerontology department. Controls: patients/subjects who have not fallen, mainly from the PROOF cohort.
Masking: None (Open Label)

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| measure of position of the pelvic and scapular girdles | The position of the pelvic and scapular girdles will be measured by the angle (in degrees) between the two girdles C7 and L5 in the sagittal plane during a 10 meters walking test. The angle will be measured by two inertial sensors of accelerometer type (IMU BNO055). | During walking test | 

Secondary Outcome Measures
