description OBJECTIVE: The primary aim of this study is to examine the effects of a backrest: using a prototype of a lumbar support presented in author's earlier study on the discomfort rating of the body parts of motorcyclist. METHODS: One hundred motorcyclists participated in this study, all in good physical condition and with no immediate complaint of musculoskeletal disorders. Each participant was asked to sit for 2 hours on a motorcycle in two different sessions (with and without the lumbar support) in a controlled room environment. At every 15 minutes interval the participants were required to rate their discomfort level on the Borg's CR-10 questionnaire. RESULTS: The rate of discomfort level (in all body parts) decreased over time during the testing period with the prototype. In terms of the discomfort 'break point', participants identified low back and upper back as the most affected body parts prior to comfort changes during the testing period with the use of the prototype. CONCLUSIONS: The use of this prototype provides a protective mechanism for the motorcyclist's musculoskeletal system, particularly the spinal column. Therefore, this prototype is capable of providing ideal posture while simultaneously enhancing the comfortability of the motorcyclist during the riding process (by reducing discomfort).<br>OBJETIVO: O objetivo principal deste estudo é analisar os efeitos de um encosto, usando um protótipo de um apoio lombar apresentado em estudo anterior do autor sobre a avaliação de desconforto das partes do corpo do motociclista. MÉTODOS: Cem motociclistas participaram neste estudo, todos em boas condições físicas e sem queixa imediata de lesões músculo-esqueléticas. Cada participante foi convidado a se sentar por 2 horas em uma moto em duas sessões diferentes (com e sem o apoio lombar) em uma sala com ambiente controlado. A cada intervalo de 15 minutos, os participantes foram solicitados a classificar o seu nível de desconforto no questionário de Borg CR-10. RESULTADOS: A taxa de nível de desconforto (em todas as partes do corpo) diminuiu ao longo do tempo durante o período de testes com o protótipo. Em termos de "ponto de ruptura" do desconforto, os participantes identificaram as partes lombar e superior das costas como as mais afetadas do corpo, antes das alterações de conforto durante o período de teste, com o uso do protótipo. CONCLUSÕES: O uso deste protótipo fornece um mecanismo de proteção para o sistema músculo-esquelético do motociclista, principalmente a coluna vertebral. Portanto, este protótipo é capaz de proporcionar a postura ideal, simultaneamente melhorando o conforto do motociclista, enquanto está pilotando a moto (reduzindo o desconforto) durante o seu uso.
