Clinical Trial Summary

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in head repositioning accuracy	Participants will be blindfolded and asked asked to, from a neutral position, to move the head into full range of motion before returning to to a neutral position again. The difference between the start and end position will be used as an estimate of head repositioning error.	Within session (session lasts approximately 2 hours)
Secondary	Change in perceived pain	Pain will be scored using a scale from 0-10 with 0 being no pain and 10 being worst imaginable pain, by drawing on body charts and choosing words from the McGill Pain Questionnaire.	Within session (session lasts approximately 2 hours)
Secondary	Change in perceived performance of head repositioning accuracy test	Likert scores of the perceived difficultness (0=no problems, 1=minimally difficult, 2=somewhat difficult, 3=fairly difficult, 4= very difficult, 5=unable to perform)	Within session (session lasts approximately 2 hours)
