Systematic review of the measurement properties of performance-based functional tests in patients with neck disorders.

Objectives: The purpose of this systematic review is to identify and synthesise studies evaluating performance-based functional outcome measures designed to evaluate the functional abilities of patients with neck pain.

Design: Systematic review.

Data Sources: A literature search using PubMed, Scopus, CINAHL, EMBASE, COCHRANE, Google Scholar and a citation mapping strategy was conducted until July 2019.

3D-imaging: a scanning light pattern projector.

The technology of electrically adjustable optical interfaces has found applications in, e.g., camera lenses, where an adjustable focal length provides automatic focusing for the camera.
