Sollividu Velli Nilavae Song Download there. Intraclass Correlation Coefficients were excellent for the CDS-PL and NDI-PL and equalled 0.93 (95% CI from 0. Results The Cronbach's alpha values were excellent for the NDI-PL in the test and in the retest (0.84, 0.85, respectively), and for the CDS-PL (0.90 in the test and in the retest). The Mann-Whitney test was applied to determine dependency between quantitative and qualitative characteristics. The Spearman's rank correlation coefficient (rS) was used to determine dependency between quantitative characteristics. We assessed the test-retest reliability using the Intraclass Correlation Coefficients (ICCs).
We used Cronbach's alpha to assess internal consistency. The mean age of the assessed group was 47.1 years (SD 8. The pain level was evaluated using the Visual Analog Scale. Sixty patients were treated due to degenerative and discopathic disorders in the cervical spine filled out the NDI-PL and the CDS-PL. Methods The translation was carried out according to the International Quality of Life Association (IQOLA) Project. The NDI and NPDS are questionnaires commonly used to measure neck pain and disability. To translate and test the psychometric properties of Thai versions of the NDI and NPDS questionnaires. Cross-cultural validation of the Neck Disability Index (NDI) and Neck Pain and Disability Scale (NPDS). Journal of Manipulative and Physiological Therapeutics, 1991, 14, 409-415. The Neck Disability Index: A study of reliability and validity. Interpretation of Neck Disability Index Scores Raw Score Relative Impairment 0-4 None 5-14 Mild 15-24 Moderate 25-34 Severe >35 Complete Source: Vernon, H. This first Spanish version of the Neck Disability Index is. 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.The Spanish version of the NDI was administered 2 or 3 times to 175. 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). 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. 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.
