Database Covering the Prayer Movements Which Were Not Available Previously
(Nature Publishing Group, 2023-05-12) Mihçin, Şenay; Şahin, Ahmet Mert; Yılmaz, Mehmet; Alpkaya, Alican Tuncay; Tuna, Merve; Akdeniz, Sevinç; Can, Nuray Korkmaz; Tosun, Aliye; Şahin, Serap
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.
Üst Ekstremite Hareket Kabiliyeti Değerlendirmesi için Yeni Bir Sistem Tasarımı
(IEEE, 2020) Çizmecioğulları, Serkan; Mihçin, Şenay; Akan, Aydın; Koçak, Mertcan; Tosun, Aliye
Üst ekstremite fonksiyon değerlendirilmesinde kullanılan yöntemlerden birisi de Eklem Hareket Açıklığı (EHA) ölçümleridir. Günümüzde bu ölçümler klinisyenin gözlemsel değerlendirmesine ve/veya gonyometrik ölçümlere dayanmaktadır. Bu ölçümlerde tekrarlanabilirlik ve güvenilirlik açısından problemler mevcuttur. Bu çalışmada üst ektremitede EHA ölçümlerinin sayısal değerlendirilmesine bağlı olarak objektif çıkarımlar yapılmasını sağlayabilecek tek kameralı bir sistem önerilmiştir. Bireylerin omuz ve dirsek fleksiyonu hareketleri kaydedilmiştir. Eş zamanlı olarak “Altın Standart” olarak OptiTrack sistemi ile de yapılan hareketler kayıt altına alınmıştır ve analiz edilmiştir. Çalışmaya 9 erkek ve 9 kadın birey katılmıştır. Hareketlerin kaydedilmesi için Kinect kamera kullanılmıştır. Kinect kamera OptiTrack sistemi ile karşılaştırılmıştır. Omuz ve dirsek fleksiyonu açıları her iki sistem ile hesaplanmıştır. Hesaplanan açılar kullanılarak her iki sistemin uyumu istatiksel olarak incelenmiştir. Bland- Altman yöntemi kullanılarak yapılan analizlerde hem erkek hem de kadın bireylerde omuz fleksiyonu ve dirsek fleksiyonu hareketleri açısından %95 güven aralığında her iki kameranın birbiriyle uyumlu olduğu tespit edilmiştir. Bu çalışma önerilen sistemin klinik tanı için güvenirliğine dair delil teşkil etmektedir.

Wearable Motion Capture System Evaluation for Biomechanical Studies for Hip Joints
(ASME, 2021) Mihçin, Şenay; Çıklaçandır, Samet; Koçak, Mertcan; Tosun, Aliye
Human motion capture (MOCAP) systems are vital while determining the loads occurring at the joints. Most of the clinical MOCAP systems are very costly, requiring investment and infrastructure. Therefore, alternative technologies are in demand. In this study, a novel markerless wearable MOCAP system was assessed for its compatibility with a biomechanical modeling software. To collect evidence, experiments were designed in two stages for quantifying the range of motion (ROM) of the hip joint, in vitro and in vivo. Three constrained single-plane motions-abduction/adduction, flexion/extension, and internal/external rotation movements of the active leg-were analyzed. The data were collected from 14 healthy volunteers, using the wearable system and a medical grade optoelectronic MOCAP system simultaneously and compared against. For the in vitro study, the root-mean-square error (RMSE) for the abduction/adduction motion of the hip joint was calculated as 0.11deg/0.30deg and 0.11deg/0.09deg, respectively, for the wearable and the opto-electronic system. The in vivo Bland-Altman plots showed that the two system data are comparable. The simulation software is found compatible to run the simulations in offline mode. The wearable system could be utilized in the field of biomechanics software for running the kinetic simulations. The results demonstrated that the wearable system could be an alternative in the field of biomechanics based on the evidence collected.
