Purpose: The purpose of this study was to compare the strength and walking ability of chronic stroke patients following either proprioceptive neuromuscular facilitation (PNF) pattern training with pressure biofeedback units (feedback group) or PNF pattern training without pressure biofeedback units (control group). Methods: Eighteen participants with chronic stroke were recruited from a rehabilitation hospital. They were divided into two groups: a feedback group (n = 8) and a control group (n = 10). They all received 30 minutes of neurodevelopmental therapy and PNF training for 15 minutes five times a week for three weeks. Muscle strength and spatiotemporal gait parameters were measured. Muscle strength was measured by hand-held dynamometer; gait parameters were measured by the Biodex Gait trainer treadmill system. Results: After the training periods, the feedback group showed a significant improvement in hip abductor muscle strength, hip extensor muscle strength, step length of the unaffected limb, and step time of the affected limb (p<0.05). Conclusion: The results of this study showed that proprioceptive neuromuscular facilitation pattern training with pressure biofeedback units was more effective in improving hip muscle strength and walking ability than the proprioceptive neuromuscular facilitation pattern training without pressure biofeedback units. Therefore, to strengthen hip muscles and improve the walking ability of stroke patients, using pressure biofeedback units to improve trunk stability should be considered.

This study examined the effects of backward walking with rhythmic auditory stimulation on the gait and balance of stroke patients. Twenty-one people were divided randomly into three groups; group I(n=7, forward walking), group II(n=7, backward walking), group III(n=7, backward walking by rhythmic auditory stimulation). Each group was trained for 30 minutes 5 times per week for 3 weeks, and was evaluated using a 10m walking test, time up and go test, functional reach test, stride length and step length asymmetry ratio. As a result, the pre- to post-test measures revealed a significant effect in each group on the gait speed, gait symmetry and balance(p<.05). The walking speed, gait symmetry and balance were higher in group II (p<.05) than in group I and it was the highest in group III(p<.05). The stride length was higher in group II and group III(p<.05) than in group I. In conclusion, for stroke patients, backward walking training with rhythmic auditory stimulation is effective on the gait speed, gait symmetry and balance.

The purpose of this study is to research the effect of walking exercise with acaiberry ingestion for 8 weeks on inflammatory markers of middle age women. The participators were aging from 40 to 50 aging healthy women. The first group is classified to ingest acaiberry(AB), the second group is classified to walking exercise with acaiberry ingestion(WE+AB), and third group is classified to just walking exercise(WE). The program was doing walking exercise 3 times per week for 8 weeks. Acaiberry ingestion is after walking exercise for 8 weeks. The amount of the acaiberry is 5g acaiberry dilutes with 100mg water to inhale before breakfast and dinner to monitor CRP of each group before ingest acaiberry and 8 weeks later how to change CRP and cardiovascular disease. Consequently, all of three groups such as: acaiberry ingestion group, walking exercise with acaiberry ingestion group, and just walking exercise group, has positive effect with WBC(white blood cell), Albumin, ESR(erythrocyte sedimentation rate), CRP(C-reactive protein), but Albumin increases very small amount of gaze. Therefore, this study has no longer period time for research, and in the future there should be more concrete and various studies, such as adding more exercise of method, intensity, and measure of ingestion for supporting this study.

Awareness effect of aquapuncture with dexamethasone on GV-26 was studied in tiletamine/zolazapam anesthetized six healthy crossbred dogs using a randomized cross-over experimental study design. After anesthesia by tiletamine/zolazapam, 0.1 mg dexamethasone was injected on GV-26 at 20 min in the experimental group. For the control group, 0.1 mg dexamethasone was injected on the quadriceps femoralis. A significant difference was evident in the sedation score between groups at 60 and 90 min (p < 0.05). A significant difference was also evident in the analgesia score at 50 and 60 min (p < 0.05). At 90 min, all dogs in the experimental group responded strongly to pain (p < 0.01). Head up time, sternal recumbent time, standing time, and walking time was shorter in the experimental group, but the difference from the control group was statistically significant only for head up time and walking time (p < 0.05). GV-26 acupuncture with dexamethasone is useful for awareness effects after anesthesia.

The effects of recording interval (1, 2, 3, 4, 5, 10, 15, 20 and 30 min) on the estimation of some grazing behavior variables in beef cows and calves (<4 months old) were investigated in a daytime grazing (7 h) system utilizing a bahiagrass (Paspalum notatum Flugge) pasture (a 1.1 ha paddock and a 0.4 ha resting area). Recording intervals of 10-30 min tended to underestimate the time spent grazing and ruminating and overestimate the time spent resting by animals, whereas intervals of 1-5 min resulted in almost constant estimates. In all grazing activities, the errors of estimation became larger when the recording interval exceeded 5 min. The accuracy of estimation was higher for grazing time>rumination time>resting time. An increase in recording interval always decreased estimates of the distance walked by animals. It was concluded that recording intervals of 1-5 min provide reliable estimates of the time spent grazing, ruminating and resting. It was also concluded that positioning of animals at 1 min intervals may provide estimates of walking distance with acceptable bias toward underestimation.

We have developed a wearable device that can convert sensor data into real-time step counts. Sensor data on gait were acquired using a triaxial accelerometer. A test was performed according to a test protocol for different walking speeds, e.g., slow walking, walking, fast walking, slow running, running, and fast running. Each test was carried out for 36 min on a treadmill with the participant wearing an Actical device, and the device developed in this study. The signal vector magnitude (SVM) was used to process the X, Y, and Z values output by the triaxial accelerometer into one representative value. In addition, for accurate step-count detection, we used three algorithms: an heuristic algorithm (HA), the adaptive threshold algorithm (ATA), and the adaptive locking period algorithm (ALPA). The recognition rate of our algorithm was 97.34% better than that of the Actical device(91.74%) by 5.6%.

To develop the wireless remote opreating system of walking rice transplanter, this study was carried out for manufacturing the wireless remote control system acting upon the transplanter. The first report of this study contained about the construction and operating method of a developed remote control system for 2-row walking type transplanter. It is the second report about the field test for an experimental transplanter being attached a wireless control system and for a conventional transplanter. The test was executed to investigate the characteristics of velocity, rectilinearity, turning time, interval of roots and of rows, and field capacity in accordance with various engine speeds for an experimental transplanter. The measurements of this test were compared with those of the conventional transplanter. The obtained results were as follows : 1. The operating velocity of the experimental transplanter was faster than the conventional one when the high speed range of the engine but the variances were very large. 2. The rectilinearity, interval of raws and of roots, and the turning time of the experimental transplanter was inferior to the conventional one at some speed ranges of the engine. 3. Field capacity of the experimental transplanter was superior to the conventional one at high speed of the engine. 4. There were some disadvantages for the experimental transplanter to operate, because it was constructed without any aid devices, such as float and hydraulic system for instance. But if the remote control system of this study equip at the modern walking transplanter, it will be improved and utilized without defects which was revealed from this test.
