Translation, Cross-Cultural Adaptation, Reliability, and Validity of the Persian Version of the Neck Outcome Score Questionnaire in Iranian Patients With Nonspecific Neck Pain.

Objective: The primary purpose of this study was to translate and culturally adapt the neck outcome score (NOOS) questionnaire into Persian language and investigate its reliability and validity.

Methods: The NOOS questionnaire was translated into Persian language and culturally adapted according to American Academy of Orthopaedic Surgeons guidelines. One hundred four patients with nonspecific neck pain were requested to complete the Persian version of the NOOS questionnaire, 36-item short form survey (SF-36), and neck disability index (NDI) questionnaire.

The Responsiveness of Three Persian Outcome Measures Following Physiotherapy Intervention in Patients with Chronic Non-Specific Neck Pain.

Objectives: A prospective cohort study to evaluate and compare the responsiveness of the Persian version of the neck disability index (NDI), neck pain & disability scale (NPDS), neck outcome score (NOOS), and to determine the minimal clinically important difference (MCID) and minimal detectable change (MDC). To date, no studies have made a direct comparison between the responsiveness of the Persian version of NPDS, NDI, and NOOS questionnaires.

Methods: At the end of the study, 55 patients with chronic non-specific neck pain completed the NPDS, NDI, and NOOS questionnaires at the beginning and end of three weeks of physiotherapy treatment.
