Purpose: The purpose of this study was to compare the effects of the FES-gait with augmented feedback training to the FES alone on the gait and functional performance in individuals with chronic stroke. Methods: This study used a pretest and posttest randomized control design. The subjects who signed the agreement were randomly divided into 12 experimental groups and 12 control groups. The experimental groups performed two types of augmented feedback training (knowledge of performance and knowledge of results) together with FES, and the control group performed FES on the TA and GM without augmented feedback and then walked for 30 minutes for 40 meters. Both the experimental groups and the control groups received training five times a week for four weeks. Results: The groups that received the FES with augmented feedback training significantly showed a greater improvement in single limb support (SLS) and gait velocity than the groups that received FES alone. In addition, timed up and go (TUG) test and six minute walk test (6MWT) showed a significant improvement in the groups that received FES with augmented feedback compared to the groups that received FES alone. Conclusion: Compared with the existing FES gait training, augmented feedback showed improvements in gait parameters, walking ability, and dynamic balance. The augmented feedback will be an important method that can provide motivation for motor learning to stroke patients.

This survey paper explores the application of multimodal feedback in automated systems for motor learning. In this paper, we review the findings shown in recent studies in this field using rehabilitation and various motor training scenarios as context. We discuss popular feedback delivery and sensing mechanisms for motion capture and processing in terms of requirements, benefits, and limitations. The selection of modalities is presented via our having reviewed the best-practice approaches for each modality relative to motor task complexity with example implementations in recent work. We summarize the advantages and disadvantages of several approaches for integrating modalities in terms of fusion and frequency of feedback during motor tasks. Finally, we review the limitations of perceptual bandwidth and provide an evaluation of the information transfer for each modality.

스포츠 클라이밍은 한정된 공간에서의 반복된 동작으로 인해 지속적인 흥미 유발이 어려울 수 있다. 또한 지도자는 시범 동작을 보여줌으로써 학습자를 이해하도록 하는 것이 중요한데, 기존의 스포츠 클라이밍 수업은 지도자가 손과 발의 위치를 일일이 가리키는 방식으로 진행되고 있다. 따라서 이러한 기존 스포츠 클라이밍 수업 방식을 대체하여 학습자가 시범 동작을 실시간으로 관찰하고 그대로 따라서 수행할 수 있는 방안에 대해 꾸준하게 요구되어 왔다. 이러한 문제를 해결하기 위해 공간증강현실 기술을 활용하여 이미지 트레이닝 한다면 학습자의 운동기능 향상 및 수업태도에 긍정적인 영향을 가져올 수 있다. 본 연구에서는 스포츠 클라이밍 학습 도구로서 CCA(Climbing Character Animation)의 효과를 검증하는 데 그 목적이 있다. 따라서 본 연구는 CCA의 유용성을 검증하기 위해 실제 스포츠 클라이밍에 적용했다. 그 결과 공간증강현실 기반 CCA를 이용한 수업이 전통적인 스포츠 클라이밍 수업보다 흥미도, 몰입 및 학습효과에 효과적인 것으로 나타났다.
