An observational study in Muscle Strength, Neck Muscle Issue and Bruxism, sponsored by Zurich University of Applied Sciences. Completed at 1 site in Switzerland. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2024-07-24.
Sponsored by Zurich University of Applied Sciences · Observational
to measure strength of the deep anterior neck muscles with a new measurement protocol and by using the NOD device, a dynamometer, in subjects with and without bruxism, and compared to EMG on the superficial muscles of the anterior neck and the masseter muscle.
151 studies on the registry are indexed under Bruxism; 39 are open to participants now.
This study's enrollment of 10 is below the median of 89 across 55 observational studies indexed under Bruxism.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
subjects with known bruxism, no TMD, primary headache or neck pain
Other: cranio-cervical flexion test with NOD
non-bruxism, no primary headache, TMD or neck pain
Other: cranio-cervical flexion test with NOD
testing the anterior neck muscles during a nodding movement and by using a dynamometer
activation score = AS
stepwise (5 steps) and correct (no substitution by the superficial muscles) activation of the deep neck flexors, that can be hold for 10 seconds: Each step increases by 3.4N. The scale will be offset, starting at 0N. Steps are accordingly: 3.4N, 6.8N, 10.2N, 13.6N, 17N. Higher scores denote better function
Time frame: baseline
performance index= PI
number of correctly performed 10 second holds at each incremental step. number between 1 and 10. Higher scores denote better function.
Time frame: baseline
Neck-Pain
neck pain, headache or discomfort during or immediate after the test protocol, measured by a numeric rating scale from 0 to 10. Higher scores denote more pain or discomfort
Time frame: baseline
Plan to share: No — data can be shared on demand
