“…Hence, the transmission of health information is impossible if the area is extremely small. In Reference [13]- [15], the walking speed is described as about 0.5 to 2.3 m/s. Walking speed was v = 1.0 m/s as average value in Reference [13]- [15].…”

This paper proposes a scheme to obtain location and vital health information using ZigBee system. ZigBee systems are wireless communication systems defined by IEEE 802.154. In the proposed scheme, location information is obtained using the Link Quality Indication (LQI) function of a ZigBee system, which represents the received signal strength. And, the vital health information are collected from the electrocardiogram monitor, the pulse and blood pressure device, attached to the patient's body. This information is then transmitted to an outside network by ZigBee systems. In this way, vital health information can be transmitted as ZigBee sensor data while patients with the ZigBee terminal are moving. In the experiments using actual ZigBee devices, the proposed scheme could obtain accurate location and vital health information from the sensor data. Moreover, to achieve high reliability in the actual service, the collected amount of sensor data was confirmed by the theoretic calculation, when a ZigBee terminal passed through ZigBee routers. These results indicate that the proposed scheme can be used to detect the accurate location of the ZigBee terminal. And over 99% of the sensor data on vital health information was obtained when the ZigBee terminal passed through approximately four ZigBee routers.

Changes in step time and trunk acceleration, at the beginning and during the steady-state phase of walking, combined with rhythmic auditory stimulation were examined in healthy adults. [Participants and Methods] Indoor level walking was performed by 17 healthy adults under two conditions: Condition 1 consisted of 20 free steps of comfortable walking; and Condition 2 consisted of walking with the initial contact matched to a rhythmic auditory stimulus based on the average step time of the 20 steps of Condition 1. The walking was divided into 4 periods of 5 steps from the start of walking. [Results] During phase Ⅰ (steps 1-5), the step time was shorter in Condition 2 than in Condition 1, and the peak values of trunk acceleration to the left and right, and up and down, and the coefficient of variation of trunk accelerations to the front and down increased in Condition 2. [Conclusion] The results suggest that when presented with rhythmic auditory stimuli at the same tempo as that of free walking, it takes about 5 steps for normal subjects to adapt their gait to the rhythmic auditory stimuli.
