  • This paper presents a force control based on the observer without taking any force or torque measurement from the robot which allows realizing more stable and robust human robot interaction for the developed multi-functional upper limb rehabilitation robot. The robot has four functional training modes which can be classified by the human robot interaction types: passive, active, assistive, and resistive mode. The proposed observer consists of internal disturbance observer and external force observer for distinctive performance evaluation. Since four training modes can be quantitatively identified as impedance variation, position-based impedance control with feedback and feedforward controller was applied to the assistive training mode. The results showed that the proposed sensorless observer estimated cleaner and more accurate force compared to the force sensor and the impedance controller embedded with the proposed observer completed the assistive training mode safely and properly.

  • The purpose of the present study is to evaluate the basic upper-limb involved in products manipulation. Upper-limb muscular deformations and electromyography (EMG) measurements are used as indexes for estimated motion: hand opening and closing, wrist extending and flexing, pronation and supination, grasping conditions. Measured values are analyzed by multivariate analysis and a regression equation is obtained for estimating the characteristics of upper-limb performance. Muscular deformation is defined as a change in shape, such as a pressure changes when the hand or wrist moves. hand opening and closing can be discriminated at a higher percentage of accuracy by muscular deformation data than by EMG data. Muscular deformation measurements using air-pack pressure sensors were verified to be effective in motion estimation applications.

  • Upper limb morbidity including shoulder pain, lymphedema, adhesive capsulitis, myofascial pain syndrome, and limited range of motions (LROMs) occurs frequently in breast cancer patients. Especially restricted upper limb motion aggravated by chronic lymphedema results in functional limitation and impaired activities of daily living (ADL). However, conventional rehabilitation therapy including complex decongestive therapy and stretching exercise is insufficient for managing advanced breast cancer patients with complex upper limb morbidity. Here, we report a case of breast cancer-related chronic lymphedema in a 62-years old female with severe LROM in all joints of the affected upper extremity that caused severe disability in ADL. Significant improvements in range of motion and upper extremity function were observed after serial extracorporeal shock wave therapy (ESWT), combined with conventional rehabilitation therapy. Therefore, ESWT might be recommended for managing the extensive limited joint motion which causes functional decline in a patient of chronic lymphedema with trophic skin change.
