Neck Disability Index (NDI)<\/h2>\r\nThe Neck Disability Index (NDI) is a modification of the Oswestry Low Back Pain Disability Questionnaire (LBPDQ), with the items and response categories adapted for people with neck pain. The NDI measures self-reported pain intensity (pain, headache) and limitations in performing daily work-related activities (work, lifting and concentration) and non-work-related activities (personal care, reading, driving, sleeping and leisure). The NDI can indicate the extent to which neck pain affects daily activities.\r\n\r\n \r\n

Validity and Reliability<\/h3>\r\nLemeunier et al. (2019)<\/a> report that the Neck Disability Index is reliable at measuring disability in people with neck pain related disorders. In individuals with chronic neck pain grades I to III, the intra-rater reliability of the Neck Disability Index was ICC = 0.64 (95% CI 0.19-0.84) with a 3-week testing interval and ICC = 0.92 (95% CI 0.85-0.96) with a 1-week testing interval. Additionally, the systematic review suggests that the Neck Disability Index is valid for assessing neck disability in people with neck pain grade I to grade III. Neck Disability Index scores were significantly correlated with self-reported improvement on the Global Rating of Change scale (Pearson's r = 0.52; p 0.000; Pearson's r = 0.58, p = 0.01), VAS pain intensity (Pearson's r = 0.63, p 0.001), health-related quality of life (SF-12 and the SF-6D) (\u2212 0.50 < Pearson\u2019s r < \u2212 0.77, p < 0.001), and health-related quality of status (EuroQol-5D, EQ-5D) (Pearson\u2019s r = \u2212 0.76, p < 0.001).\r\n\r\n \r\n

Scoring and Interpretation<\/h3>\r\nScores range from 0 to 5 for each of the 10 items. The top score is 50. A percentage score can be created by multiplying the acquired score by two. On rare occasions, a respondent will omit to answer a particular question. The average of all other items is then added to the completed items.\r\n\r\nScoring intervals for interpretation:\r\n
