News Finding: The researchers say this is an essential component for movements that feel natural.
Paper Finding: The ranges for the lower and upper thresholds across users were 10 to 30% and 60 to 150%, respectively.
News Context: For example, patients could turn the hand slowly but open it quickly at the same time. The researchers say this is an essential component for movements that feel natural. Professor Farina hopes to eliminate the need for this in future prototypes, without sacrificing personalisation to specific patients.
Paper Context: After adjustment, the applied range varied from user to user and between the different prosthetic functions. The ranges for the lower and upper thresholds across users were 10 to 30% and 60 to 150%, respectively. Both methods allowed for proportional control: The stronger the user contracted the muscles, the faster the prosthesis moved or the higher the grip force in case an object was grasped.
