In Toyota Regional Medical Center, seamless daily activity monitoring system, Karada station(Toyota Tsusho corp., Nagoya, Japan) started in April 2019. This system consists of cloud server, the PC and the measurement device. The device is a waist-worn 3D – accelerometer and can measure steps, which can be viewed at the device screen anytime. The device can also recognize upright posture. You can check in and out just by putting the device over the PC and pressing several buttons. The PC records the exercise time and count steps during the exercise. You can view the number of daily total steps and the one during exercise for the last two weeks on the PC screen. Walking 100 steps with the device revealed that accuracy was 97.2 (4.18) %.
Sixteen patients who walks independently, supervised were recruited in the rehabilitation ward. Within one week after admission they started to wear the device all the time except for bathing or sleeping time. At the beginning and the end of every physical therapy (PT), the therapist took the patient to the PC and check in and out, giving feedback with the health data.
The average number of daily total steps on the 1st day and the last day was 3328 (1552) steps and 4200 (2369) steps, respectively. The one during PT on the 1st day and the last day was 1725 (598) steps and 2208 (869) steps, respectively.
The monitoring system, Karada station can count daily steps during PT and the other. This feedback is easily to understand for the patients and can be useful for the therapists to make PT plan each day. Moreover, it is comfortable enough to carry and the measurement system makes it possible to monitor daily activity seamlessly for inpatients and outpatients.
