Ningjia Yang, Matti Itkonen, Fady Shibata-Alnajjar, Noriaki Hattori, Makoto Kinomoto, Kouji Takahashi +13

RA-L 2020

Sit-to-stand (STS) motion is an important daily activity and many post-stroke patients have difficulty in performing the STS motion. Post-stroke patients who can perform STS independently, still utilize four muscle synergies (synchronized muscle activation) as seen in healthy people. In addition, te

A Novel Approach to the Segmentation of sEMG Data Based on the Activation and Deactivation of Muscle Synergies During Movement

Álvaro Costa-García, Matti Itkonen, Hiroshi Yamasaki, Fady Shibata-Alnajjar, Shingo Shimoda

RA-L 2018

The muscle-synergy hypothesis is a widely used method for describing simple motion patterns and how the central nervous system deals with the complexity of controlling a large set of muscles in parallel. However, the physiological interpretation of synergies and the mathematical techniques behind th

Effect of Physical Therapy on Muscle Synergy Structure During Standing-Up Motion of Hemiplegic Patients

Hiroki Kogami, Qi An, Ningjia Yang, Hiroshi Yamakawa, Yusuke Tamura, Atsushi Yamashita +11

RA-L 2018

Stroke patients suffer from declined physical ability, and it is important to analyze rehabilitation intervention and clarify its effect on the motion of patients. In this study, the effect of intervention on the standing-up motion of stroke patients is investigated. First, the intervention timing o

Grasp-training Robot to Activate Neural Control Loop for Reflex and Experimental Verification

Shotaro Okajima, Fady S. Alnajjar, Hiroshi Yamasaki, Matti Itkonen, Álvaro Costa García, Yasuhisa Hasegawa +1

ICRA 2018poster

Using a rehabilitation robot to activate motion intention and reflex response simultaneously is an effective approach to aiding recovery from paralysis caused by neurological disorders. Mechanical motions supported by conventional robots are, however, not enough to activate reflex. In this paper, we…
