Modification of a Surfboard in Shape and Fin, for People With Balance Problems Due to Neuromuscular Disabilities

Overview

Different types of surfboards, with different parts that affect the "behavior" of these when riding them. Each part has a variety of modifications that are used for a specific type of person, sea condition, or category, such as: speed, balance, and maneuverability. It was identified that the main limitation of people with neuromuscular disabilities (NMD) when practicing surfing is balance. Therefore, the purpose of this research was to build a prototype of a surfboard for people with NMD, using a different shape and fin of a conventional surfboard to provide more balance. The hypothesis formulated was that the prototype for people with NMD would provide more balance time than a conventional board. Before making the prototype to scale model, it was embodied in an isometric paper. For the elaboration of the prototype, the following modifications were made: nose rocker raised to a front progression of 9.8 inches in reference to the horizontal, flat tail rocker with an inclination of 2.77 degrees with a "squash" shape, rounded edge or "rail" combined with the style "carving" and "bottom V" modified to vertical form linked to the fifth fin. When comparing the prototype with a conventional surfboard, the results reflected a 30-second increase in balance time. In conclusion, the prototype provides a longer balance time to people with NMD. The results obtained may allow people with NMD could practice this sport as part of their rehabilitation or physical activity.
