However, occlusion problems have hindered the acquisition of the data. In this work, several modifications to the 3D Motion Analyzer System to improve its efficacy are proposed. First modification is the improvement in markers tracking module to overcome the occlusion problem, and the second one is automation of the subjects’ anthropometry processing to minimize the possibility of error in data processing. The improved systems are then utilized to obtain 3D gait parameters and upper body motion during gait of 50 male and 50 female subjects as part of a continuous effort to establish Indonesia gait database. Prior to data acquisition, the subjects’ anthropometry data and body posture are examined to ascertain normalcy. The subjects’ weight and height are also assessed to ensure that they are in normal range according to Body-Mass Index (BMI) criteria. We have compared our results to those obtained in literature. The spatio-temporal and gait parameters of the subjects are in agreement with those found in literature. Furthermore, the improvements have been successfully implemented to overcome the occlusion problem and improve the program efficiency through the addition of automation of input data from a source file. Overall, the parameters obtained from this research show that the 3D Motion Analyzer system would serve the purpose of gait parameters determination well. Hence, the system has the potential for utilization as a medical diagnostic tool.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Gait analysis,gait database,gait parameters,motion analyzer.,upper body motion[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.promfg.2015.07.047[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
