Literature sharing: Brain-computer Interface-Based Soft Robotic găng tay phục hồi chức năng for đột quỵ - đột quỵ Center

Background：chi trên impairment is common in đột quỵ and can have a devastating impact on the daily lives of đột quỵ survivors. Conventional phục hồi chức năng strategies targeting vận động impairments in đột quỵ survivors include the multidisciplinary treatments of vật lý trị liệu and occupational liệu pháp. Recently, techniques such as constraint-induced chuyển động liệu pháp, mirror liệu pháp (MT), and robot-assisted liệu pháp utilise end effector systems. While such approaches have been reported to be efficacious in several studies, they largely require a minimum level of residual chuyển động of the paretic limbs to carry out, and this excludes a large proportion of đột quỵ bệnh nhân, such as in the case of CIMT. Using brain-computer interface (BCI)-based vận động imagery (MI) presents an alternative means of phục hồi chức năng to address the issue faced by bệnh nhân with negligible residual chức năng vận động.

Objective: This randomized controlled feasibility nghiên cứu investigates the ability for lâm sàng application of the Brain-Computer Interface-based Soft Robotic găng tay (BCI-SRG) incorporating các hoạt động sinh hoạt hàng ngày (ADL)-oriented tasks for phục hồi chức năng sau đột quỵ.

Methods: Eleven recruited chronic đột quỵ bệnh nhân were randomized into the BCI-SRG or Soft Robotic găng tay (SRG) group. Each group underwent a 120-minute intervention per session comprising 30-minute standard cánh tay liệu pháp and 90-minute experimental liệu pháp (BCI-SRG or SRG). To perform ADL tasks, the BCI-SRG group used vận động imagery-BCI and SRG, while the SRG group used SRG without vận động imagery-BCI. Both groups received 18 sessions of intervention over 6 weeks. Fugl-Meyer vận động Assessment (FMA) and Action nghiên cứu cánh tay Test (ARAT) scores were measured at baseline (week 0), post-intervention (week 6), and follow-ups (week 12 and 24). In total, 10/11 bệnh nhân completed the nghiên cứu with 5 in each group and 1 dropped out.

kết quả: Though there were no significant intergroup differences for FMA and ARAT during 6-week intervention, the cải thiện of FMA and ARAT seemed to sustain beyond 6-week intervention for BCI-SRG group, as compared with SRG kiểm soát. Incidentally, all BCI-SRG subjects reported a sense of vivid chuyển động of the đột quỵ-impaired chi trên and 3/5 had this phenomenon persisting beyond intervention while none of SRG did.

Conclusion: BCI-SRG suggested probable trends of sustained functional improvements with peculiar kinesthetic experience outlasting chủ động intervention in chronic đột quỵ despite the dire need for large-scale investigations to verify statistical significance. Adding BCI to soft robotic training for ADL-oriented phục hồi chức năng sau đột quỵ holds promise for sustained improvements and elicited perception of vận động movements.

As the sáng tạo brain-computer interface-based soft robotic găng tay (BCI-SRG), the Syrebo bàn tay robot phục hồi chức năng (BCI) based on the principles of vận động imagery and neural plasticity can đạt được a "perception-kiểm soát" bidirectional closed-loop neural stimulation, significantly improving phục hồi chức năng hiệu quả. It adopts a brain-inspired algorithm to capture EEG, ensuring dữ liệu accuracy. At the same time, It can collect EEG signal dữ liệu and can be viewed on software, providing references for phục hồi chức năng programs and lâm sàng nghiên cứu.
