Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigates if/how an experimentally applied neck muscle pain influences head repositioning error in healthy participants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Healthy volunteers will participate in a single session study with a crossover design.

During the study healthy participants will be randomized to either receive a injection of hypertonic saline (painful injection) or isotonic saline (control injection) in a neck muscle.

Head repositioning accuracy will be assessed with and without performing a cognitive task.
