脳卒中の生存者の80%以上が歩行困難を経験し、これは彼らの日常生活、独立性、総合的な生活の質に大きな影響を与えます。しかし、マサチューセッツ大学アムハースト校の新しい研究では、独自のロボット式ヒップ外骨格が歩行機能を向上させるトレーニングツールとして開発され、脳卒中のリハビリテーションに新たな可能性をもたらすことが示されました。このアプローチは、現在のリハビリテーション方法よりもアクセスしやすく、日常生活に移しやすい新しい治療法を可能にします。

Abstract

Wearable exoskeletons show significant potential for improving gait impairments, such as interlimb asymmetry. However, a more profound understanding of whether exoskeletons are capable of eliciting neural adaptation is needed. This study aimed to characterize how individuals adapt to bilateral asymmetric joint stiffness applied by a hip exoskeleton, similar to split-belt treadmill training. Thirteen unimpaired individuals performed a walking trial on the treadmill while wearing the exoskeleton. The right side of the exoskeleton acted as a positive stiffness torsional spring, pulling the thigh towards the neutral standing position, while the left acted as a negative stiffness spring pulling the thigh away from the neutral standing position. The results showed that this intervention applied by a hip exoskeleton elicited adaptation in spatiotemporal and kinetic gait measures similar to split-belt treadmill training. These results demonstrate the potential of the proposed intervention for retraining symmetric gait.
