Determination of a Minimal Clinically Important Difference of the Functional Reach Test in the Elderly.

Study Overview
=================
Brief Summary
-----------------
The main objective of the study is to determine the Minimal Clinically Important Difference of the Functional Reach Test in the Elderly by a statistical method. The first secondary objective of the study is to determine the Minimal Clinically Important Difference by the Anchor method based on a qualitative assessment by the patients of their own response. The second secondary objective is to determine the Minimal Clinically Important Difference by the Delphi method, based on the search for a consensus between physiotherapists specializing in geriatrics.

Detailed Description
-----------------
The French population is aging, and geriatric rehabilitation care must adapt to this growing population. The functional reach test is a common clinical test in geriatrics. It helps to determine the risk of falling. However, its metrological qualities are not all determined. The Minimal Clinically Important Difference (MCID) is in particular unknown for this test. The MCID of a test makes it possible to personalize in a way more in-depth evaluation of physiotherapy treatment. So it is necessary to characterize this essential metrological determinant of a common balance skills assessment tool.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Diagnostic Test: Functional Reach test|The determination by statistical research is carried out during a usual physiotherapy assessment of the volunteers. Data patient demographics and standard tests (FRT, Tinetti test, Timed Up and Go test, unipodal station) will be noted. A satisfaction questionnaire inspired by Patient rating of change will be sent to participants for the determination of the MCID by ANCHOR method. Concerning the Delphi method, a questionnaire will be sent to physiotherapists with proven geriatric activity.|
