Usefulness of Scissors with a Power-Support Mechanism to Assist Thumb Movement: An Observational Study

Abstract: Long-term repetitive movements, such as opening and closing scissors, increase strain on muscles and joints. Amplitude probability distribution function (APDF) analysis of surface electromyogram (sEMG) data was used to quantify the burden of muscle activity. We aimed to test the hypothesis that scissors with a power-support device assist repetitive thumb movements to reduce potential myoelectric activity. Twenty female university students who met the eligibility criteria performed a cutting experiment, with an… Show more

“…A plausible situation where material choice may be relevant is when a user relies on the tactile stimuli from the gripping of the scissors for ease of use and comfort. For such cases, additional materials may be needed to implement additional components to the design of scissors, such as wires that assist the closing and opening of scissor blades [16]. The materials and components would then have to be calibrated for the user, inclusive of the factor of handedness.…”
