One of the essential training position is performed in the squat position which can affect the walking patterns of the dancers. This study aimed to compare the lower extremity kinematics in the sagittal, frontal, and transverse planes during walking between Khon masked dancers and non-dancers. Method: It used convenience sampling technique and twenty healthy males (10 Khon masked dancers and 10 healthy males) were participated in the study. Professional Khon masked dancers who had at least 5 years of dancing experience in giant or monkey role play and all participants were 20 to 40 years’ healthy male with body mass index (BMI) of 18.5 – 30 kg/m2. Participants walked at a self-selected speed on the 9-meter walkway in the 3D motion analysis setting located at Faculty of Physical Therapy, Mahidol University. Results: Kinematics variables included the angles of pelvic tilt, obliquity, and rotation, hip and knee flexion/extension, adduction/abduction, internal rotation/external rotation, and ankle dorsiflexion/plantarflexion were collected and evaluated. Kinetics variables including anterior, posterior, medial, lateral, and vertical forces were also monitored. Data were then statistically analyzed between professional dancers and non-dancers by using the independent sample t-test with a level of significance of p<0.05. There was no significant difference in all testing variables between the two groups of participants. However, Khon masked dancers revealed higher anterior pelvic tilt angle at terminal swing and external rotation angle at terminal stance, hip flexion angle at mid-swing, knee flexion angle at loading response, and adduction at mid-swing. Gait pattern in Khon mask dancers demonstrated increased pelvic anterior tilt in conjunction with the increased lumbar lordosis. Conclusion: This study demonstrated that long-term Khon training was not significantly affected in the gait patterns of the dancers. However, more sample size is still necessary for the future to investigate a clearer picture of gait alteration in Khon masked dancers.MedicineConference PaperSCOPUS2-s2.0-851886759542586940X
