DEVELOPMENT OF A MAGNETORHEOLOGICAL GLOVE DESIGNED FOR HAND REHABILITATION

Öz

The aim of hand rehabilitation is to maximize the remaining functional capacities of the hands and upper extremities of injured, operated, or diseased people. This study proposal aims at developing a rehabilitation device, in which magneto-rheological (MR) fluid is used to realize the fundamental isometric exercise motions in order to support the inadequate and weak muscles according to required amount of reaction. The viscosity of MR fluids increase in miliseconds and the fluid act like a solid. It again returns to its initial state as the application of magnetic field is stopped. The controllability of the rheological properties of MR fluid via magnetic field forms the starting point of this study: In the cases of hand rehabilitation, exercises needed to strengthen the muscles can be realized by changing the magnitude of the magnetic field of the box in which the MR fluid is stored. Solidification and softening of the MR fluid will force the hand in the glove, which will be placed inside the box. The study aimed in this study consists of a box with coils attached around and filled with MR fluid under a certain magnetic field. By altering the electromagnetic field, it will be possible to change the hardness of the MR fluid according to the patient’s state

MANYETOREOLOJİK SIVI İLE EL REHABİLİTASYON CİHAZİ TASARIMI VE ÜRETİMİ

Öz

Bu çalışmanın çıkış noktası, MR akışkanların reolojik özelliklerinin manyetik alan ile kontrol edilmesidir. Bu doğrultuda rehabilitasyon gerektiren el ve üst ekstremite vakalarında kasların güçlendirilmesini sağlayacak egzersiz hareketleri, manyetoreolojik sıvının hapsedildiği manyetik alan içerisinde gerçekleştirilebilmektedir. Manyetik alan ile MR sıvısının katılaşması veya yumuşamasıyla el ve parmak hareketleri güçlendirilerek kas gücünün ve fonksiyonel hareketinin arttırılması sağlanmaktadır. Bu çalışmada geliştirilen cihaz, içi MR sıvısı ile dolu olan ve çevresindeki sargılar ile üzerine manyetik alanın uygulandığı bir kutudan oluşmaktadır. Elektrik akımının kontrolüyle MR sıvının sertlik derecesi, hastanın gelişimine göre ayarlanabilmektedir
