The purpose of this study was to determine the association between postural kyphosis and fatigue among dentistry students of Cebu Doctors' University (CDU). This study was conducted in CDU located in 1 Dr. P. V. Larrazabal Jr. Avenue, North Reclamation Area, Mandaue City, Cebu. The respondents who participated were 22 male and 83 female fifth and sixth year dentistry students who are officially enrolled at CDU. Primarily, there were 157 total number of fifth and sixth year dentistry students. However, only 105 were able to complete the assessment and questionnaire and the remaining 52 students were excluded (24.8% refused, 5.7% had scoliosis and back problems, 2.5% had recent injuries related to the spine). A descriptive correlational design was used to determine the association between postural kyphosis and fatigue. The instruments used were the Flexicurve ruler utilized by the licensed physical therapists to measure the postural kyphotic angle and the Chalder Fatigue Questionnaire to determine presence or absence of fatigue of the students.
Pearson correlation coefficient was utilized in this study to determine the association between postural kyphosis and fatigue. The study showed that the entire respondents had normal kyphosis and the majority experienced fatigue. The results showed that 100% (n=105) of the respondents had normal kyphosis with an average degree of 26.13. Majority of the respondents experienced fatigue 71.4% (n=75) while 28.6% (n=30) of the respondents did not experience fatigue. Pearson correlation results showed that there is no correlation between the degree of postural kyphosis and the presence of fatigue among the respondents (r=.058).
Based on the clinical analysis of the data gathered, it was found that fatigue has no association to postural kyphosis among fifth and sixth year dentistry students of Cebu Doctors' University. The researchers would like to recommend on assessing other postural risk factors that are prevalent such as forward head posture that may be associated with fatigue. To extend the scope of the study, the researchers also recommend on assessing practicing professional dentists. For future studies, the researchers would also like to recommend on having a Flexicurve assessment seminar to properly introduce the procedure of the tool since it is still uncommon in the Philippines.
