Primary |
Heart-rate variability (HRV) |
the changes in the inter-beat intervals (IBIs) that will be used to quantify the amount of HRV observed during monitoring periods (<1 min to >24 h). In this study, the monitoring period will be five minutes |

Primary |
Visual analog scale (VAS) |
Current pain intensity will be measured using a 10-cm VAS with endpoints marked 'no pain' at 0 and 'worst pain imaginable at 10. |

Secondary |
Pressure pain threshold (PPT) |
A digital pressure algometer (Somedic AB, Farsta, Sweden) with a surface probe of 1 cm2 and a rate of 40 kPa/s will be used to quantify the pain intensity. The measurement will be taken on the painful area. Participants will be instructed to activate a button when the sensation of pressure becomes painful, and the resultant value will be recorded. Three measurements will be performed. The average value will be recorded for analysis. |

Neck Disability Index (NDI) |
The NDI is a self-assessment questionnaire for the specific functional status of individuals with neck pain. It consists of ten sections: pain, personal care, weight gain, reading, headache, concentration, work, driving, sleeping, and leisure. Each section is scaled from 0 to 5, where 0 represents "painless" and 5 represents "the worst pain imaginable." The points obtained are added to a total score. |
