Lower body implants are designed according to the boundary conditions of gait data and tested against. However, due to diversity in cultural backgrounds, religious rituals might cause different ranges of motion and different loading patterns. Especially in the Eastern part of the world, diverse Activities of Daily Living (ADL) consist of salat, yoga rituals, and different style sitting postures. A database covering these diverse activities of the Eastern world is non-existent. This study focuses on data collection protocol and the creation of an online database of previously excluded ADL activities, targeting 200 healthy subjects via Qualisys and IMU motion capture systems, and force plates, from West and Middle East Asian populations with a special focus on the lower body joints. The current version of the database covers 50 volunteers for 13 different activities. The tasks are defined and listed in a table to create a database to search based on age, gender, BMI, type of activity, and motion capture system. The collected data is to be used for designing implants to allow these sorts of activities to be performed.
Database covering the previously excluded daily life activities

In biomedical engineering, implants are designed according to the boundary conditions of gait data and tested against. However, due to diversity in cultural backgrounds, religious rituals might cause different ranges of motion and different loading patterns. Especially in the Eastern part of the world, diverse Activities of Daily Living (ADL) consist of salat, yoga rituals, and different style sitting postures. Although databases cover ADL for the Western population, a database covering these diverse activities of the Eastern world, specific to these populations is non-existent. To include previously excluded ADL is a key step in understanding the kinematics and kinetics of these activities. By means of developments in motion capture technologies, excluded ADL data are captured to obtain the coordinate values to calculate the range of motion and the joint reaction forces. This study focuses on data collection protocol and the creation of an online database of previously excluded ADL activities, targeting 200 healthy subjects via Qualisys and IMU motion capture systems, and force plates, from West and Middle East Asian populations. Anthropometrics are known to affect kinematics and kinetics which are also included in the collected data. The current version of the database covers 50 volunteers for 12 different activities, the database aims for 100- male and 100- female healthy volunteers as the final target including C3D and BVH file types. The tasks are defined and listed in a table to create a database to make a query based on age, gender, BMI, type of activity and motion capture system. The data is collected only from a healthy population to understand healthy motion patterns during these previously excluded ADLs. The collected data is to be used for designing implants to allow these sorts of activities to be performed without compromising the quality of life of patients performing these activities in the future.
Investigation of hip joint kinematics for daily life activities
(01. Izmir Institute of Technology, 2022-12) Tuna, Merve; Mihçin, Şenay
The daily life activities of a population have a significant effect on hip joint due to the repetitiveness and difficulty levels. Therefore, daily life activity data is an important source for manufacturing successive and long-lasting implants for hip joint arthroplasty. In this study, the hip joint kinematics is investigated under six determined activity that is performed frequently by the Turkish population. The collected and processed data is used in a TUBITAK funded project to form a first national database for the Turkish people. The study first introduces the literature review on hip joint kinematics investigations for daily life activities. Thereafter, anatomy of the hip joint and motion capture techniques are explained. Experimental procedure, protocol, materials, methodology and data collection are explained in detail in the Methodology Chapter. This Chapter introduces the determined daily life activities, chosen motion capture system and post-processing tools for the inverse kinematic analysis. The Results and Discussion Chapter illustrates and tabulates the calculated results. Detailed explanations are made for discussing the results. The Conclusion Chapter summarizes the study.
