Tragus-to-wall: A systematic review of procedures, measurements obtained, and clinimetric properties.

Objective: Our purpose was to summarize the literature on the applicability, procedures for performing, and clinimetric findings related to the measurement of tragus-to-wall (TTW) distance.

Method: Pubmed, Scopus, and CINAHL databases were systematically searched using the key words "tragus" AND "wall". Articles were examined for information on the participants whose TTW distance was measured, the procedures used for measuring TTW, and findings regarding TTW distances measured and the clinimetric properties of the measurements.
