The Hidden Impact of Mouse Position on Neck and Shoulder Pain

Many people focus on chair setup or monitor height when addressing discomfort at work, yet mouse positioning is one of the most common sources of unnecessary strain.

Small changes in reach distance can significantly increase muscle workload.

Why Mouse Placement Matters

When the mouse sits too far away from the body:

• The shoulder must abduct or reach forward

• Upper trapezius muscles remain active continuously

• Forearm and wrist strain increases

  
  

This sustained activation contributes to fatigue and pain, particularly by the end of the workday.

Signs Your Mouse Position May Be Contributing

Common indicators include:

• Shoulder tightness on one side

• Pain between the shoulder blade and neck

• Forearm fatigue or wrist discomfort

• Leaning toward one side during computer use

These symptoms often develop gradually rather than suddenly.

How to Improve Mouse Position

Adjustments that reduce load include:

• Placing the mouse close to the keyboard

• Keeping elbows relaxed beside the body

• Avoiding reaching forward or sideways

• Allowing the forearm to remain supported where possible

  
  

Reducing reach distance decreases muscle activation immediately.

How Ergonomics Helps

Ergonomics focuses on minimising unnecessary effort:

• Supports neutral arm positioning

• Reduces sustained shoulder muscle activity

• Prevents gradual overload injuries

  
  

Small positioning changes often deliver significant relief.
