Abstract

This is an analytical study on the relationship of jeepney driver's seat with low back pain occurrence among BDDC-Zapote drivers. The general objectives of the study was to determine if the design of jeepney seats is a causative factor in developing low back pain among drivers of DBBC-Zapote route. The study was conducted at the DBBC-Zapote jeepney terminal. Data were gathered through questionnaire. Results obtained showed (1) There is a strong correlation between preferred posture, seat angle adjustment and occurrence of LBP in jeepney drivers after and while driving. (2) There is moderate correlation between the characteristics or quality of the jeepney's seat cushion, presence of a headrest and seat cushion with the occurrence of LBP. (3) There is weak correlation between seat height, distance of the seat to the steering wheel, presence of headset and back cushion with the occurrence of LBP> (4) And no correlation between presence of back with regards to the occurrence of LBP. An analytical study is used. The researchers made use of survey type questionnaire written in Filipino. The questionnaire were distributed to the available subjects and then collected afterwards. A letter was given to Mrs. Cantimbulan asking for permission to implement the study. After it was approved, questionnaire was given to the available subjects. Each questionnaire given to the drivers was accompanied by an open letter explaining the purpose of the study and introducing the researchers. The questionnaire was collected the following day. After gathering the data, books and journals was used to aid for the completion of the papers. After gathering all important data from questionnaire collected from sample population, appropriate tables, figures and graphs were used to summarize the gathered data for analysis. All numeric data were computed to percentages to determine the frequency distribution of the respondents in each category. Phi coefficient was used to find for the correlation between the design of jeepney drivers seat and occurrence of low back pain. after thorough study, results obtained from our respondents yielded a strong connection between the design of jeepney drivers seat and LBP, specifically, preferred posture, time of driving (while/after) and seat angle adjustment. Other contributory factors showing a moderate correlation includes having or not having seat cushion, headrest and the quality of seat cushion. Having or not having headrest. Adjuster, back cushion, seat height and distance of seat to steering wheel may be possible minor factors since results showed weak correlation. There was no correlation established between having of not having backrest. All of the factors are important in preventing low back pain, since all major or minor factors paly a part in its development. Base on the results of the study, it was found out the the seat angle adjustment, and the faulty/ preferred posture is the major contributing factor in the occurrence of LBP. Therefore the group can suggest or recommend that the seat amgle necessary to have a proper back posture. Likewise, adaptation or modication necessary if not possible to change its main components. This can be accomplish through reading materials, pamphlets, brochures to be given to the drivers especially made (simple and easy to understand) through the effort of rehabilitation members. Likewise, rehabilitation professional are encourage to inform or educate jeepney drivers, manufactures about the importance of an ergonomic jeepney seat as a contributory and preventive factor in the development of low back pain. This study will enlighten the readers in choosing ergonomic equipment for the prevention of LBP.
