Klinik Araştırma Koleksiyon | A wearable EEG-Temelli Assistive BCIs Sistem for Inme rehabilitasyonu - Inme Merkez

Araştırma background
The combination of BCI and auxiliary Robot is a Yeni Tedavi for inme rehabilitasyonu. However, most of the existing Çalışma is Temelli Açık Karmaşık Sistem setups, expensive and bulky equipment. In this Çalışma, a wearable EEG beyin-bilgisayar arayüzü Sistem for el işlevi rehabilitasyon is designed to do clinial Deneme. This Sistem is composed of customized EEG cap, commercial amplifier, and hand dış iskelet. In addition, the Sistem includes the visual Arayüz for the convenience of Kullanıcılar. The Deneme enrolled six healthy participants and two inme Hastalar to verify the Güvenlik and Etkinlik of the Sistem.

Yöntem

To verify the Güvenlik and Etkinlik of the Sistem, 6 healthy subjects(1 female and 5 males, aged 23±3 years Eski) from Shanghai Jiao Tong Üniversite and 2 inme Hastalar(all Doğru hand affected) from the rehabilitasyon Departman of Huashan Hastane were recruited to participate in the Çalışma. A 6-Dakika Eğitim session was conducted for each Konu, in which the subjects performed Doğru-hand motor execution(inme Hasta’s affected hand to make a Hareket attempt) according to visual cues. A red rectangle appears Açık the Doğru or Merkez of the screen, indicating Eylem execution (or attempt) or Dinlenme, respectively. The task lasts for 4 seconds until the white cross disappears. It is recommended that healthy subjects repeat clenching and extending fists 3-4 times, and inme Hastalar are instructed to make motor attempts during motor tasks. The Çevrimiçi Test was similar to the Eğitim session, except that all red rectangles appeared in the Merkez of the screen, which allowed subjects to Seç to move their hand (or Egzersiz attempt) or Dinlenme at will. Test Sonuçlar are provided to Kullanıcılar visual and proprioseptif Geri bildirim via a screen and hand dış iskelet shortly after task Tamamlama. There are three Çevrimiçi Test runs, each containing 20 Denemeler. Each Konu Mayıs Dinlenme between runs. All subjects were asked to refrain from any additional facial or arm Kas Hareket throughout the experiment.

Sonuç

The Ortalama Doğruluk of Çevrimdışı and Çevrimiçi Eğitim is 84.91% and 79.38%, respectively. Seven subjects had Çevrimiçi Doğruluk of more than 70%, five more than 80%, and one more than 90%.

The Etkinlik-related Spectral Perturbation(ERSP) showed that the sensorimotor cortex was activated in both α and β bands during Doğru hand Hareket Eğitim, with stronger activation Açık the Aynı Yan. Meanwhile, as expected, the uncontrolled Devlet showed Hayır Önemli activation Açık either the C3 or C4 channels. In the Çevrimiçi Test, both the left and Doğru hemispheres were activated to perform Doğru-handed movements.

 

Sonuç

This Çalışma demonstrates a wearable beyin-bilgisayar arayüzü Sistem for el işlevi rehabilitasyon after inme. The Sonuçlar of motor task Farklılaştırma preliminarily Onayla the feasibility of this Cihaz, which shows Harika Klinik Başvuru potential.
