Abstract
Introduction: Motorcycles are recognized as a highly convenient and economical means form of transportation both locally and internationally. From ergonomic perspective, the motorcyclists riding discomfort has become an issue that might be detrimental to health which requires high demand on ergonomic intervention. There is a relation between motorcycle road accidents with the cases of human error due to fatigue. In order to improve the motorcyclist’s discomfort which leads to fatigue and become a factor of accidents, an ideal sitting posture can be achieved by providing a backrest. However, current motorcycle seat design is still lacking with this feature. Objectives: Therefore, this study was conducted to evaluate the effectiveness of the posture support on reducing riding discomfort among motorcyclists. Methodology: This study was conducted among undergraduate female students in Universiti Putra Malaysia, Serdang, Selangor. A total of 80 students (40 respondents in each control and experimental group) were recruited in this study. Respondents who participated in this study meets all the requirements of inclusive criteria. The experimental group were required to wear posture support with Truposture smart shirt while control group only provided with Truposture smart shirt (real-time spine movement monitoring device) while riding for a duration of 20 minutes in 10km. Both groups rode the motorcycle using similar route and motorcycle model. After completed 10km of riding, respondents were required to rate their discomfort level using Borg's CR-10 questionnaire. Results: This study found that the respondents changed their postures irregularly and unconsciously as they try to adapt with the riding process and environment. The respondents experienced the most discomfort on their lower back, buttocks, tailbone, and upper buttocks. There is statistical difference of median for the discomfort rating on all body parts (-1.96 >z> 1.96), p<0.001) except for upper left and right thigh, lower left, and right thigh and both left and right-side leg. The Mann-Whitney U test indicated that motorcycle seat feature with no lower back support or backrest, induced pain in waist region and overall discomfort due to motorcycle seat was significantly higher (-1.96 >z> 1.96), p<0.05) in control group compared to experimental group. Conclusion: The findings proved that posture support intervention was successfully maintains and improves the riding posture angle ergonomically and reduce the discomfort on motorcyclist’s riding posture. However, future study needs to be undertaken with larger sample size and longer distance. Other factors and variables that influenced body part discomfort symptoms also should be considered in this study. Keywords: Motorcyclists, Posture Support, Riding Discomfort, Truposture Smart Shirt.
