This paper describes the development of a gait rehabilitation system with a locomotion interface (LI) for home-visit rehabilitation. For this purpose, the LI should be compact, small, and easy to move. The LI has two 2 degree-of-freedom (DOF) manipulators with footpads to move each foot along a trajectory. When the user stands on the footpads, the system can move his or her feet while the body remains stationary. The footpads can have various trajectories, which are prerecordings of the movements of healthy individuals walking on plane surfaces or slopes. The homes of stroke patients may have not only flat surfaces but also some slopes and staircases. The quadriceps femoris muscle is important for walking up and down slopes and staircases, and the eccentric and concentric contractions of this muscle are, in particular, difficult to train under normal circumstances. Therefore, we developed a graded-walking program for the system used in this study. Using this system, the user can undergo gait rehabilitation in their home, during visits by a physical therapist. An evaluation of the results of tests showed that the vastus medialis muscles of all the subjects were stimulated more than by walking on real slopes.

This paper describes the development of a gait rehabilitation system with a locomotion interface (LI) for training patients to climb stairs. The LI consists of two 2-DOF manipulators equipped with footpads. These can move the patient's feet while his or her body remains stationary. The footpads follow the prerecorded motion of the feet of healthy individuals. For gait training, the patient progresses sequentially through successively more advanced modes. In this study, two modes, the enforced climbing of stairs and interactive climbing of stairs, were developed. In the interactive mode, foot pressure sensors are used to realize interactive walking. Comparisons were made between the modes for healthy individuals and a patient. The effectiveness of the system was examined using electromyography (EMG) and foot pressure data.

This paper describes the development of an integrative system for gait rehabilitation. The system can present visual images and the sensation of walking to a user. The system consists of a locomotion interface, “GaitMaster4,” and a spherical immersive projection display. The locomotion interface moves the users' feet while it keeps their bodies in the real world. Wide-angle images captured from an omnidirectional camera are projected onto the immersive projection display. To evaluate the system, subjects' brain activity was measured using near infrared spectroscopy (NIRS), and the effectiveness of the system was confirmed.

Rehabilitation System

A split belt treadmill for gait rehabilitation was developed to improve the symmetry of the stance phase time of patients with stroke. The system, which increases the stance phase time of the affected leg and then realizes a well-balanced gait, is divided into two components. First, the stance phases of the sound and affected legs were measured and presented visually in real time to the patient and physical therapist as biofeedback. Second, using stance phase biofeedback, the physical therapist sets two different velocities of treadmill belts for sound and affected legs. In an experiment, 11 patients with chronic stroke participated in a short-term intervention trial (20 gait cycles) of the developed treadmill system. Three of the five subjects who had lost balance between the stance phase of the sound leg and that of the affected one improved their gait balance in the intervention trial. In addition, one subject kept the well-balanced gait after the intervention.

Body Weight Support System

This paper proposes a body weight support (BWS) system with a series elastic actuator (SEA) to facilitate walking assistance and motor relearning during gait rehabilitation. This system comprises the following: a mobile platform that ensures movement of the system on the ground, a BWS mechanism with an SEA that is capable of providing the desired unloading force, and a pelvic brace to smooth the pelvis motions. The control of the body weight support is realized by an active weight-offload method, and a dynamic model of the BWS system with offload mass of a human is conducted to simulate the control process and optimize the parameters. Preliminary results demonstrate that the BWS system can provide the desired support force and vertical motion of the pelvis.

Consumption of fruits and vegetables rich in carotenoids has been widely reported to prevent cardiovascular diseases. However, the relationship between serum carotenoid concentrations and visceral fat area (VFA), which is considered a better predictor of cardiovascular diseases than the body-mass index (BMI) and waist circumference, remains unclear. Therefore, we examined the relationship in healthy individuals in their 20s or older, stratified by sex and age, to compare the relationship between serum carotenoid concentrations and VFA and BMI. The study was conducted on 805 people, the residents in Hirosaki city, Aomori prefecture, who underwent a health checkup. An inverse relationship between serum carotenoid concentrations and VFA and BMI was observed only in women. In addition, the results were independent of the intake of dietary fiber, which is mainly supplied from vegetables as well as carotenoids. This suggests that consumption of a diet rich in carotenoids (especially lutein and beta-carotene) is associated with lower VFA, which is a good predictor of cardiovascular disease, especially in women. This study is the first to comprehensively evaluate the association between serum carotenoid levels and VFA in healthy individuals.

Abstract A description is provided for Entomophthora grylli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Orthoptera; nymph and adults of grasshoppers and locusts; there have also been records on Lepidoptera, Diptera and Coleoptera (MacLeod & Muller-Kogler, 1973). GEOGRAPHICAL DISTRIBUTION: Europe, including Britain; Canada; East, Central and South Africa. Fresenius quotes a record at 6000 ft near St. Moritz. DISEASE: The disease, causing epizootics in red locusts, Cyrtacanthacra septemfasciata (Nomadacris septemfasciata), in S. Africa is described by Skaife (1925). Infection is by germinating conidia which penetrate the integument. Dying insects characteristically climb up grass stems and die, apparently embracing the stem. The body becomes soft and easily disintegrates. The abdomen curls upward and backwards. Shortly after death a white, buff or greenish furry growth appears from the intersegmental membrane, leg joints, junction of the head and thorax and at the base of the antennae. The growth is made up of club-shaped conidiogenous cells which forcibly discharge conidia around the dead insect. Conidia, coated with the sticky contents of the conidiophore, are discharged in the evening, when the insects are clustered together and adhere to the surface of healthy individuals. A total of about 1% of locusts throughout the season die showing no external growth but are filled with resting spores; other individuals appear to be immune.

BACKGROUND Balance training in young adults may increase coordination, cognitive function or the symmetry of strength on both sides of the body. It is an essential tool for injury or fall prevention and a precondition for becoming a professional athlete. OBJECTIVE The aim of this study was to assess the effect of Xbox 360 Kinect training on postural balance in young, healthy individuals. METHODS The study enrolled 75 individuals who were randomly assigned to three equal groups. The first group (Group VR) performed exercises on an Xbox 360 Kinect console, and the second group (Group T) performed conventional all-round exercises. The third group was a control group (Group C). Each group underwent balance assessments on the Biodex Balance posturographic platform, including the Balance Error Scoring System test, before and after the training cycle. The level of statistical significance was set at P<.05. RESULTS Group VR and Group T achieved statistically significant improvements in the sway index compared with baseline. Group T gained significant decrease in the sway index on the unstable surface (P=.002). Group VR and group T demonstrated significant decreases in the mean sway index on stable and unstable surfaces (group VR — P=.035; group T — P=.001) Group C did not achieve a statistically significant improvement in the sway index. None of the groups demonstrated a statistically significant decrease in the test error count. CONCLUSIONS Virtual reality in the form of video games played on an Xbox 360 Kinect console may be an effective method of balance training in healthy individuals.
