Performing laparoscopic surgery requires several skills, which have never been required for conventional open surgery. Surgeons experience difficulties in learning and mastering these techniques. Various training methods metrics developed to assess improve surgeon's operative abilities. While are currently widely being used, skill evaluation still far from objective the regular education. This study proposes a methodology of defining processing model that objectively evaluates surgical...

The IMU primarily contains a mother board for sensing, Bluetooth module data transmission PC, and Li-Polymer battery power supply. is provided microcontroller 9-axis sensors (miniaturized MEMS accelerometer, gyroscope magnetometer) to measure orientation. A quaternion-based extended Kalman filter (EKF) integrated...
EMG sensors for biomechanics research and portable applications need to be small, wireless power efficient. This imposes several constraints on the design methodology of such sensors. There are many commercially available devices which expensive have proprietary communication protocols. It is difficult synchronize them with other devices. Furthermore, using gel-based electrodes signal acquisition increases setup time running costs. Hence we present a miniaturized, wireless, low-cost...
A large amount of hemiplegic survivors are suffering from motor impairment. Ankle rehabilitation exercises act an important role in recovering patients’ walking ability after stroke. Currently, patients mainly perform ankle exercise to reobtain range motion (ROM) and strength the joint under a therapist’s assistance by manual operation. However, therapists suffer high work intensity, most existed devices focus on functional training ignore importance neurological early stage. In this paper,...

In our elderly-dominated society, there is considerable expectation for a growing need home, medical, and nursing care services to assist this aging both from the physical psychological points of view. Among these services, special importance has rehabilitation process specifically clinical assessments motor abilities. The current process, however, lacks objectiveness. Our research aimed at development portable Bioinstrumentation System that can objectively measure assess physiological...
The increasing age of the world population is posing new challenges to our society, such as how keep this aging healthy and active despite age. In recent years, there has been a lot interest for gait analysis rehabilitation purposes well performance assessment population. While current systems work well, they still have several limitations. Cost, need specialized personnel, be used in research center, sporadic measurement prevent these from being widely used. authors propose use extremely...
The number of stroke patients is rapidly increasing in the elderly society, which leads to growing demand for lower limb rehabilitation training. Currently, one patient needs two or more therapists assistance during gait It results shortage therapists' population, furthermore, heavy works load on therapist. emerging robotic technologies provide a solution assist therapist, and corresponding researches have been reported. However, most existing robots adopt single-arm double-arm structure,...
In recent years there has been an ever increasing amount of research and development technologies methods to improve the quality performance advanced surgery. several fields, such as laparoscopy, various training metrics have proposed, both surgeon's abilities also assess her/his skills.
