Abstract This paper is regarding the wearable device design which is based on frozen shoulder game rehabilitation. At present some studies are focus on sensors and rehabilitation outcomes. However the sensors designed without a suitable wearable device and it will influence the sensed results and wear comfort. Thus, this article records the design process of the wearable device, particularly the worn ways and the fabric. The way in which wearable device are worn will be analyzed with the user experience to improve sensing accuracy and comfort. The material in which wearable device are used will be tested with making models. Then the models of the wearable devices are made and tested to find out the design factors which are suitable ergonomic. Keywords Rehabilitation

1 Introduction Frozen shoulder or adhesive capsulitis is a disease affecting patients mainly on people aged from 40 to 60 years old [1]. It is an extremely painful and debilitating condition leading to stiffness and disability due to the soft tissue in the joint of fibrosing and adhesions [2]. In general, the longer the stiffness stage lasts the longer is the recovery stage stays [3]. Currently, the treatment ways of the frozen shoulder have physical therapy, intra-articular, steroid injection, intra-articular sodium hyaluronate, oral steroid therapy, and acupuncture [2]. According to Bo J. Lundberg [1] research, adjuvant therapy consisting of intensive physiotherapy by promoting regeneration of the synovial tissue appears that the affected area return to normal state [1]. Hence the main treatment combined with rehabilitation exercise will get better and faster healing influences. However the long time and single rehabilitation exercise makes patients feel boring, tedious and painful. That is why the frequency of motion will become less and less. At present, some research teams began to develop the game-based rehabilitation exercise. Recently, some literature studies the virtual reality game-based treatment system on the wall and made each training step adjustable based on the patient’s physical condition [4]. Yeh, Lee
