The patients are evaluated at entry and 6 months after the end of the outpatient rehabilitation by the same qualified physiatrist. At entry, scales of demonstrated reliability, validity and sensitivity are administered to assess comorbidity (evaluated with Cumulative Illness Rating Scale-Geriatrics), pain severity (10-point analogue scale), neck range of motion (manual goniometer), and neck disability (Neck Disability Index). Adherence to home exercises is evaluated 15 days and 6 months after the end of the outpatient rehabilitation and is self-reported.
