|---|---|---|---|---|
| cranio-cervical flexion test with NOD | Other | testing the anterior neck muscles during a nodding movement and by using a dynamometer |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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 | 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. | baseline |
| Measure | Description | Time Frame |
|---|---|---|
| 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 | baseline |
