Abstract
Neurorehabilitation using a brain–computer interface (BCI) requires machine learning, for which calculations take a long time, even days. However, the demands of actual rehabilitation are becoming increasingly rigorous, requiring that processes be completed within tens of minutes. Therefore, we developed a new effective rehabilitation system for treating patients such as those with stroke hemiplegia. The system can smoothly perform rehabilitation training on the day of admission to the hospital. We designed a heuristic BCI with simplified fuzzy reasoning, which can detect motor intention signals from an electroencephalogram (EEG) within several tens of minutes. The detected signal is sent to the newly developed ankle rehabilitation device (ARD), and the patient repeats the dorsiflexion motion by the ARD.

As of 2016, Japan’s elderly population, people older than 65 years old, was 34.61 million, accounting for 27.3% of the whole population [1]
According to Ministry of Health, Labor, and Welfare statistics, the primary reason for care nursing is stroke, which accounts for 21.5% of all cases requiring care [2]
We developed two methods: (1) heuristic brain–computer interface (BCI) using fuzzy template matching (FTM), because the process quickly and extracts characteristic EEG patterns, and (2) ankle rehabilitation devices (ARDs) that change the load automatically according to the degree of contracture
Summary
As of 2016, Japan’s elderly population, people older than 65 years old, was 34.61 million, accounting for 27.3% of the whole population [1]. According to Ministry of Health, Labor, and Welfare statistics, the primary reason for care nursing is stroke, which accounts for 21.5% of all cases requiring care [2]. Cerebral stroke causes intellectual disability and language disorders, together with hemiplegia of every body part including the legs. Training to improve range of motion and muscle strength is typically conducted using a continuous passive motion (CPM) device [3,4]. Such efforts are ineffective after the chronic phase more than six months after cerebral infarction
