The manipulation of chopsticks requires skillful motions of fingers. Therefore, it would be difficult to manipulate chopsticks for people with hand dysfunction. We designed a simple and convenient utensil, the pincer chopsticks, to simulate the pincers-pinching operation of traditional chopsticks. To compare the performance of the new device with that of traditional chopsticks and spoons, 32 volunteers applied these utensils to pick up four kinds of fool with either hand. For dominant hands, the manipulation time of both pincer and traditional chopsticks was shorter than that of spoons, while using pincer chopsticks with non-dominant hands revealed the best performance among the three experimental utensils for users without experience. In this study, the newly designed pincer chopsticks demonstrated advantages for operation and performance. It has the potential to benefit patients with impaired hands.

[Purpose] When using chopsticks with a standard grip, the lower chopstick is held firmly; the upper chopstick dominates the motion between open and closed postures. This study's primary aim was to evaluate the stability of the lower chopstick when maneuvering with the dominant hand. The secondary goal was to test whether using chopsticks with the non-dominant hand improves the stability of the lower chopstick.

Background: The purpose of this study was to clarify the influence of manipulation mode of chopsticks on the learning process, using assessment of task performance and electromyography, and to understand the significance of the traditional manipulation mode from the viewpoint of physiological anthropology. Previous studies have described two modes of manipulating chopsticks, the traditional pincers-pinching mode and the scissors-pinching mode.
Methods: We conducted experiments with two conditions of holding chopsticks: scissors mode and pincers mode.

Chopsticks are the main utensils for daily dining in Asia. Lee and Chen (2008) designed a novel auxiliary device for chopsticks that successfully converts people experienced in scissor-pinching to the correct method: pincer-pinching. This study attempts to assess the optimal combination of auxiliary size and location on chopstick stems for food-gripping performance.

Chopsticks are popular dining utensils in many Asian countries. It is well recognized that the pincers-pinching mode has been recommended for chopsticks operation for Chinese dining. The objective of this study was to propose an auxiliary device for transferring the subjects who had experienced scissors pinching to that of pincers pinching.
