Implication

Randomized trial evaluates cervical assistive device efficacy in reducing neck strain among office workers, suggesting improved comfort and productivity.

Key Points

This study aims to develop and evaluate a novel ergonomic device for reducing neck strain in office workers through mechanical support.
Designed an ergonomic assistive device based on human cervical spine dynamics.
Evaluated performance using IMU and EMG sensors on 20 healthy subjects comparing conditions with and without the device.
Analyzed range of motion and muscle activation using paired t-tests to assess effectiveness.
NACK reduced cervical mobility by 30-50% across all anatomical planes compared to without device.
EMG analysis showed sternocleidomastoid activation decreased by 23-29% MVC (p < 0.01).
Upper trapezius muscle activation reduced by 10-15% MVC (p < 0.05).
