“…The reason for choosing this method is that the spinal sitting pattern studies were limited to laboratory and clinical settings only [ 2 , 21 ]. According to Ma’arof et al [ 22 ], the research field provides vital outcomes and real-world motorcycling information. Thus, TruPosture Smart Shirt is the most suitable method to monitor the spinal change pattern among motorcyclists on-road with the application of real working conditions.…”

“…An upright riding posture is the best posture in riding this type of motorcycle based on the standard operating procedure (SOP) of Honda CBX750P motorcycle riding. According to Ma’arof et al [ 22 ], a good riding posture for the upright posture is that the arms should bend slightly when gripping the throttle and sitting in the upright position. The shoulders and elbows are held easily on the holds without exceeding or over-expanding the elbows.…”

Effectiveness of lumbar support with built-in massager system on spinal angle profiles among high-powered traffic police motorcycle riders: A randomised controlled trial

Traffic police riders are exposed to prolonged static postures causing significant angular deviation of the musculoskeletal, including the lumbar angle (L1-L5). This postural alteration contributes to awkward posture, musculoskeletal disorders and spinal injury, especially in the lower back area, as it is one of the most severe modern diseases nowadays. Thus, the study aimed to evaluate the effect of lumbar support with a built-in massager system on spinal angle profiles among traffic police riders. A randomised controlled trial (pre-testpost-test control design) was used to assess spinal angle pattern while riding the high-powered motorcycle for 20 minutes. Twenty-four traffic police riders were randomly selected to participate and 12 riders were assigned to the control group and 12 riders to the experimental group. The pre-test and post-test were conducted at a one-week interval. Each participant was required to wear a TruPosture Smart Shirt (to monitor spinal posture). The TruPosture Apps recorded the spinal angle pattern. The data indicated that the police riders using motorcycle seat with lumbar support and built-in massager system showed a huge improvement in maintaining posture which only involves slight spinal angle deviation changes from the spinal reference angle throughout the 20 minutes ride. The data collected then were analysed using the Mann-Whitney test and Wilcoxon signed-ranked test to verify a statistically significant difference between and within the control and experimental groups. There were significant differences in all sensors between the control group and experimental groups (p<0.05) and within the experimental group. According to the findings, it can be said that the ergonomic intervention prototype (lumbar support with built-in massager system) successfully helps to maintain and improve the natural curve of the spinal posture. This indirectly would reduce the risk of developing musculoskeletal disorders and spinal injury among traffic police riders.

“…The origin point is located at a distance of 1000 mm along the X-axis and 350 mm from the floor (ground) [27,29]. Since the remaining ten dimensions (as shown in Figure 3) are also required for the basic construction of motorcycle simulators [3], the dimensions were measured using a standard procedure which is recognized in the previously published research articles [32][33][34][35]. These dimensions were measured through landmarks in handlebar, seat, fuel tank, and footrest.…”

“…The use of the simulator for training purposes is very limited in the South-Asian region due to lack of awareness and the high cost of the commercially available simulator. From literature, it is observed that amongst the notable simulators, MORIS Motorcycle Simulator, Postura Motergo [3], University of Padova Motorcycle Simulator (UNIPD), and Honda Smart Trainer are used in Malaysia and India, respectively. It has also been found that there is a lack of credible information like research publications on motorcycle dimensions.…”

Out of many plausible causative factors for the spike in accidents, lack of riding skills is reported to be a significant reason for motorcycle mishaps. The riding skills can be improved through better availability of training facilities (simulator). Non-availability of the dimensional database (of different types of motorcycles), which are essential for simulator design, makes it difficult for the designers/ engineers to build the commercially available cheaper motorcycle-simulators. Moreover, the available measuring techniques and devices are costly and unable to satisfy motorcycle measurement's diverse requirements. Thus, the present research aimed to prepare the dimensional database of motorcycles using an in-house fabricated measuring instrument. Following the adaptive design method, the alpha prototype of a laser-pointer-based measuring instrument was developed. The calibrated device was used for measuring the dimensions associated with the handlebar, seat, and footrest of the 23 different motorcycles under study. Detailed (linear, angular, and circumferential) dimensions of the handlebar, seat, and footrest were measured using sliding calipers and protractors. Generated dimensional databases of 18 critical dimensions from the handlebar, seat, and footrest of the 23 different standard-motorcycles would be useful for deciding the motorcycle simulator's dimensions.
