Overview

People with hand and wrist conditions, such as carpal tunnel syndrome or hand injuries, often experience pain and discomfort when using a computer mouse. This study will evaluate a new artificial intelligence (AI)-assisted computer input system ("AI-mouse") designed to reduce the amount of hand movement needed during computer tasks. Participants will complete short computer-based tasks using both a conventional mouse and the AI-assisted system while researchers measure task performance, muscle activity using surface electromyography (EMG), and participants' ratings of pain, physical strain, and usability. The study aims to determine whether the AI-assisted system can reduce physical effort and muscle load while maintaining effective computer interaction. Findings may help improve accessible computer technologies and support the development of ergonomic tools for people with hand and wrist impairments.

Interventions

  • Device AI-Assisted Computer Input System
    A non-invasive computer input system that uses artificial intelligence to predict the user's intended on-screen action. Instead of relying primarily on continuous cursor movement and mouse clicking, the system presents predicted actions that participants can preview, accept, or discard using minimal keyboard input. The intervention is designed to reduce repetitive hand movements during computer interaction while preserving user control. Participants complete standardized computer tasks using the
  • Device Conventional Computer Mouse
    A standard computer mouse used for conventional point-and-click interaction. Participants complete the same standardized computer tasks as in the experimental condition, allowing direct comparison of task performance, upper-limb muscle activity measured by surface electromyography (EMG), and participant-reported pain, physical strain, and usability.

Primary outcome measures

  • APDF90 surface electromyography (sEMG) amplitude [Time frame: Baseline (during each intervention condition on Day 1)]
  • Muscular rest time [Time frame: Baseline (during each intervention condition on Day 1)]
Secondary outcome measures (5)
  • Integrated squared dynamic acceleration [Time frame: Baseline (during each intervention condition on Day 1)]
  • 90th percentile dynamic acceleration [Time frame: Baseline (during each intervention condition on Day 1)]
  • Task completion time [Time frame: Baseline (during each intervention condition on Day 1)]
  • Error rate [Time frame: Baseline (during each intervention condition on Day 1)]
  • Self-reported pain [Time frame: Immediately after each intervention condition on Day 1]

Eligibility criteria

Inclusion criteria

  • Adults aged 18-65 years
  • Diagnosis of a hand or wrist condition, including carpal tunnel syndrome or hand/wrist injury.
  • Receiving care at the Hand Surgery Department of the National Scientific Center of Traumatology and Orthopedics.
  • Medically stable and assessed by a study physician as able to safely perform light computer-based hand movements.
  • Able to understand the study procedures and provide written informed consent.
  • Normal or corrected-to-normal vision sufficient to complete computer-based tasks.

Exclusion criteria

  • Severe pain or acute symptoms that may be aggravated by computer task performance.
  • Postoperative restrictions limiting hand or wrist movement.
  • Severe motor impairment preventing completion of the study tasks.
  • Cognitive or neurological disorders that interfere with understanding study procedures or task performance.
  • Uncorrected visual impairment that interferes with computer use.
  • Any medical condition that, in the opinion of the study physician, would make participation unsafe.
