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.

This study was to investigate the effects of upper and lower limb composing patterns of PNF(proprioceptive neuromuscular facilitation) on the static balance ability by 20 subjects for 6 weeks. This study was measured left one leg standing and right one leg standing with closed eyes on Good Balance system. These results led us to the conclusion that the mean speed of X, Y direction, COP(center of Pressure) velocity moment showed a statistical decrease when applying post-exercise. The above results from this study indicated that upper and lower limb composing patterns of PNF exercise has improved the static balance ability. As a result, this study showed that upper and lower limb composing patterns exercise improve the ability of balance in young adults. Based on this study, it may be applied to old people.

This study appealed for a shoulder pain, and visited all 25(15 Non capsular lesions, 10 capsular lesions) patients to the objects. We executed study to the objects to a patient to agree with us after explaining a purpose and object of this study. Urged warning, and all executed eight times over about the patient who executed taping therapy for five weeks so as not to be able to get other therapy treatment. Application way of taping therapy applied all once at random generally five taping therapy to apply to limbs end of upper at clinical so far. Operated on the results about pain decrease, and we calculated as compared before and after five taping therapy. Also, operated again on them in a taping therapy judged that there was pain decrease, and we returned them to home. We make a comparative analysis for a pain after and before a treatment as we use the VAS which is evaluation of a pain in this study. The results of this study are as follows. Appeared so as operated, and a pain decrease change of Non capsular lesions became lower with a the average of 2.3 after a taping therapy in the average of 6.4s former a treatment, and to note statistically later Taping therapy of upper limb end part.(P<0.01). The pain decrease change of capsular lesions of a shoulder joint pain index decreased with the average of 4.0 after a taping therapy treatment in the average of 6.0 former a treatment after Taping therapy of upper limb end part, but were not able to note statistically.(P>0.05) Taping therapy of upper limb end part is positive to pain decrease of shoulder joint in the above-mentioned study can affect, and can especially get the effective conclusion that was able to affect from pain decrease of Non capsular lesions.

The utilization of virtual reality is increasing not only in games but also in medical care such as rehabilitation. Due to the convenience, the motion of the upper limb is detected using a non-contact method using video or a handheld type mouse, etc. In this paper, we implemented a glove which can measure finger movements and upper limb movements by using flex sensors whose resistance value changes according to the degree of folding and inertial sensors which can obtain direction information in space. We showed the upper arm movements including finger movements with signals obtained from the implemented glove on the open software platform, Processing. The sensitivity of each finger movement was 0.5deg, and the sensitivity of the upper limb motion was 0.6deg.

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.

Kendo is one of the popular sports in modem life. Head, wrist and thrust attack are the fast skill to get a score on a match. Human muscle skeletal model was developed for biomechanical study. The human model was consists with 19 bone-skeleton and 122 muscles. Muscle number of upper limb, trunk and lower limb part are 28, 60, 34 respectively. Bone was modeled with 3D beam element and muscle was modeled with spar element. For upper limb muscle modelling, rectus abdominis, trapezius, deltoideus, biceps brachii, triceps brachii muscle and other main muscles were considered. Lower limb muscle was modeled with gastrocenemius, gluteus maximus, gluteus medius and related muscles. The biomechanical stress and strain analysis of human muscle was conducted by proposed human bone-muscle finite element analysis model under head, wrist and thrust attack for kendo training.
