  Purpose

The purpose of this study is:

  1. to develop a standardised orientation and mobility training (O&M-training) in the use of an identification/symbol cane by older adults with low vision, and;
  2. to evaluate this newly developed standardised O&M-training with respect to effectiveness and feasibility in a randomised controlled trial.
