Anthropometric analysis of tricycle designs

A comparison of the designs of two types of tricycles available in India for the use of persons with severe both-lower-limb disability was made from the viewpoint of the anthropometric characteristics of the users It was noted that neither design was compatible with the disabled persons' anthropometric dimensions in a number of ways. The seats did not provide for comfortable sitting. Although the hand crank was relatively well positioned in one, the distance of the crank from the back rest obliged the users to bend forward while driving their tricycles. The study concluded that suitable modifications in the dimensions of the tricycles are required to provide greater comfort, safety and ease of operation.
