About

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

Full description

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.

Sex: All

Ages: 18 to 50 years old
