While the sample size of some of the analyses is somewhat small, this study demonstrated that the NDI achieved a high degree of reliability and internal consistency. Disability Index (NDI), and asses their measurement properties in a Nepalese neck pain population. Secondly, in a larger subset of 30 subjects, NDI scores were compared to scores on the McGill Pain Questionnaire, with similar moderately high correlations (0.69-0.70). rating scale (NRS) for neck pain intensity and the Neck. First, on a smaller subset of 10 patients who completed a course of conservative care, the percentage of change on NDI scores before and after treatment was compared to visual analogue scale scores of percent of perceived improvement in activity levels. Concurrent validity was assessed in two ways. The alpha coefficients were calculated from a pool of questionnaires completed by 52 such subjects resulting in a total index alpha of 0.80, with all items having individual alpha scores above 0.75. Originally published in 1991 in the Journal of Manipulative and Physiological Therapeutics, the Neck Disability Index (NDI) is an instrument to measure patient-reported disability secondary to neck pain.It was developed utilizing the Oswestry Low Back Pain Index as a model and therefore, at the time of its creation, was distinguished from other simpler pain assessments by examining patient. Test-retest reliability was conducted on an initial sample of 17 consecutive 'whiplash'-injured patients in an outpatient clinic, resulting in good statistical significance (Pearson's r = 0.89, p less than or equal to. Face validity was ensured through peer-review and patient feedback sessions.

A modification of the Oswestry Low Back Pain Index was conducted producing a 10-item scaled questionnaire entitled the Neck Disability Index (NDI). Methods of assessment for such disability, especially those targeted at activities of daily living which are most affected by neck pain, are few in number. Injuries to the cervical spine, especially those involving the soft tissues, represent a significant source of chronic disability.
