Biomedical Substrates of the Two-Point Cane Technique: A Review of Research
By Wall, Robert; Journal of Visual Impairment and Blindness, Vol. 96, No. 2, pp. 86-97Publication Date: February 2002
Article focuses on research on the biomechanical elements of the two-point touch technique, which is the most common long cane technique utilized by people with visual disabilities. The technique is generally used when traveling long stretches of terrain, in outdoor environments, in clear spaces, and whenever a person is traveling at a consistent or quick pace. The cane is used to warn the traveler of upcoming obstacles, and to provide a clear walking path. The traveler holds the long cane in the dominant hand at the body's midpoint, and out from the body as the arm and cane form a straight line. The fingers and thumb are wrapped around the grip, while the index finger points downward along the shaft of the cane. The cane tip is swept to the left and right in an arc in front of the traveler so that he or she can detect obstacles. Research has supported the hypothesis that this technique is a very safe and efficient method of travel for people with visual disabilities.
