Visualizing Stroke Recurrence Risk from "Daily Life Data"

MEDIROM MOTHER Labs Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative: Yoshio Uekusa) and MEDIROM Rehab Solutions Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Kosuke Ito), both part of the Medirom Group which operates healthcare businesses, jointly conducted a study on recurrence prevention support for post-stroke patients in the chronic phase, combining biometric data from wearable devices and daily life records. The results of this study were presented by Masumi Tsuruno, a physical therapist at MEDIROM Rehab Solutions, which operates the 'Cerebral Infarction Rehabilitation Center,' at the 51st Annual Meeting of the Japanese Stroke Society. In this study, we attempted to identify behaviors and conditions that could lead to recurrence risk by utilizing objective data obtained in daily life and reviewing lifestyle habits. As a result, a change in awareness regarding lifestyle management was confirmed, suggesting the possibility of contributing to recurrence prevention support in cooperation with primary care physicians. ■ Background and Purpose Stroke has a high risk of recurrence, and managing lifestyle habits is considered important. On the other hand, physical and psychological burdens that arise in daily life are difficult to grasp, which is one of the challenges in recurrence prevention. In this study, focusing on the relationship between resting heart rate and blood pressure elevation shown in previous research, we investigated the possibility of utilizing objective data obtained from wearable devices combined with daily life records to identify potential recurrence risk factors in daily life and for reviewing lifestyle habits. ■ Method One case of a post-cerebral hemorrhage patient in the chronic phase was targeted, and the following methods were used for the study. Period: 3 weeks Measurement method: Data acquired every minute by a wrist-worn device Acquired items: Heart rate, steps, etc. Daily life records: The patient recorded things they noticed, the reasons, and the time (mental state, physical condition changes, etc.) For analysis, heart rate in a state of zero steps was extracted, and after calculating the average and standard deviation, values 2SD or more above the average were extracted as abnormal values. Furthermore, the time zones where abnormal values were confirmed were cross-referenced with daily life records, and factors were examined and lifestyle adjustments were confirmed through review interviews. ■ Results Through the analysis of acquired data and cross-referencing with daily life records, an increase in heart rate was confirmed in the following situations: Movements involving physical exertion such as cooking and garbage disposal Straining during toilet activities Mental stress such as impatience, anxiety, and tension Changes in physical condition upon waking or standing Through these reviews, a change in the subject's awareness of lifestyle management was confirmed. ■ Discussion In this study, since the measurements were taken using a non-medical wearable device, with the premise of certain limitations in measurement accuracy, it became possible to concretely review daily life by combining objective data and daily life records. As a result, a change in awareness regarding lifestyle management was confirmed, suggesting the possibility that this initiative could contribute to recurrence prevention support in cooperation with primary care physicians. ■ Future Developments Based on the knowledge gained from this study, the Medirom Group will continue to further investigate the possibility of health management support utilizing daily life data. For individuals: Support for reviewing lifestyle habits For corporations: Utilization in the health management domain (e.g., REMONY) We will continue to consider how healthcare services can combine data and on-site support. ■ About the device used: "MOTHER Bracelet®︎" In this study, we used the "MOTHER Bracelet®︎," a chargeless wearable device developed by MEDIROM MOTHER Labs. This device does not require charging due to its thermoelectric generation technology, enabling continuous data acquisition 24 hours a day, 365 days a year, and supports measurement of heart rate, steps, sleep, body surface temperature, calories, etc. It continuously visualizes various data in daily life, supporting the understanding of health status and the review of lifestyle habits. It presents a new way of support based on objective data in the medical and healthcare domain. ■ About Cerebral Infarction Rehabilitation Center Since 2014, the Cerebral Infarction Rehabilitation Center has offered a new option of out-of-pocket rehabilitation, supporting functional recovery and life reconstruction primarily for post-stroke sequelae. Physical therapists, occupational therapists, and other specialists provide one-on-one support, offering rehabilitation programs tailored to each individual's goals.
