Primary Outcome Measures
NameTimeMethod
performance index= PIbaseline

number of correctly performed 10 second holds at each incremental step. number between 1 and 10. Higher scores denote better function.

activation score = ASbaseline

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

Secondary Outcome Measures
NameTimeMethod
Neck-Painbaseline

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
