Overview

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).
