The purpose of this study was to determine reliability and validity of the Neck Disability Index (NDI) now in use for the first time in neck pain patients of Korea. Fifty subjects (26 males and24 female) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that include pain intensity, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. Reliability was determined by intra-class correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NDI scores to the Visual Analog Scale (VAS) score. The Test-retest reliability of the translated versions of the NDI was good ICC (2,1) = .90 (95%CI .85 .95). Cronbach's alpha value for NDI was found to be .95 and this was statistically significant (p<.05). The criterion-related validity coefficients was .72 (p<.01). We conclude that the Korean version of NDI has shown to be a reliable and valid instrument for the assessment of neck pain.

Nephrogenic diabetes insipidus (NDI) can cause nonobstructive hydronephrosis. Congenital NDI (CNDI) is caused by a genetic mutation. This case report presents a 12-year-old girl who was incidentally diagnosed with nonobstructive hydronephrosis due to NDI caused by AQP2 gene mutation after being evaluated for microscopic hematuria found on routine health examination at school. The patient's medical and family history was unremarkable, and she complained of nocturia only at the time of the clinic visit. Bilateral hydronephrosis on abdominal ultrasonography prompted a water deprivation test, leading to diagnosis of NDI. Genetic study confirmed p.Asn (AAC)123Ser (AGC) in exon 2 of the AQP2 gene. Polyuria and hydronephrosis improved following arginine-vasopressin therapy. CNDI responsive to treatment should be considered as a possible cause of nonobstructive hydroureter.

Objectives : The purpose of this study was to analysis the relationship between hours of smartphone use and neck pain in university students. Methods : A survey of 2,353 university students was conducted in Gyeonggi province and Incheon city using a self report questionnaire from April 1 to 11 2013. The questionnaire of questions regarding the hours of using smartphone, mainly used function in participant's smartphone and neck discomfort degree. Neck disability index(NDI) was used to evaluate degree of pain. The collected data were analyzed with the t-test and Kendall's tau test using the SPSS 21.0 program and R 3.1.0, respectively. Results : 1. Almost all of the survey participants(99.07 %) were smartphone users. 66.97 % of them answered that they use their smartphone daily more than 2 hours and 48.18 % of them answered that they use their smartphone 10 to 30 minutes everytime they use it. 2. The overall distribution of NDI scores was 'no disability(0~4 score, 62.92 %)', 'mild disability(5~14 score, 32.85 %)', 'moderate disability(15~24 score, 1.19 %)'. As a result of t-test, we found that the average NDI score for female students was significantly higher than the average NDI score for male students(p<0.05). 3. The Kendall's tau test revealed that total time spent daily using smartphones has a strong positive correlation with 'pain intensity', 'lifting', 'reading' 'headache', 'concentration', and 'driving'(p<0.05) in NDI. Also, time duration of one time smartphone usage has a strong positive correlation with 'pain intensity', 'lifting', 'reading', 'headache', 'concentration', 'work', and 'recreation'(p<0.05). 4. The Kendall's tau test revealed that total NDI scores have a significantly strong positive correlation with both of total time spent daily using smartphones(p<0.05) and time duration for one time smartphone usage(p<0.05). This results imply that long-time use of smartphone has a strong relationship with neck pain. Conclusions : The results of the study would be a good starting point for future studies to reduce the risks of chronic neck pain caused by smartphone usage.

Objective: Several muscles surrounding neck are vital not only for neck motion, but for upper extremities motions as well. Neck pain would affect neck and shoulder disability. The Neck Disability Index (NDI), Shoulder Pain and Disability Index (SPADI), and Visual Analogue Scale (VAS) are increasingly used to evaluate treatment effectiveness after chronic neck pain. The purpose of this study was to analyze the correlation of neck pain, shoulder pain, and quality of life in patients with chronic neck pain. Design: Cross-sectional study. Methods: Forty-three patients with neck pain participated in this study. Participants were instructed to place a mark on each item of three clinical measures that best represented their experience of his/her neck and shoulder problem over the last week. The outcome measures of the study were NDI, SPADI, and VAS for neck and shoulder pain and disability. Results: The NDI was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The VAS-Neck was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Total was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and VAS-Shoulder (p<0.05). The SPADI-Pain was significantly correlated with the NDI, VAS-Neck, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Disability was significantly correlated with the NDI, VAS-Neck, SPADI-Total, SPADI-Pain, and VAS-Shoulder (p<0.05). The VAS-Shoulder was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and SPADI-Total (p<0.05). Conclusions: Neck disability in patients with chronic neck pain should be considered with disability and pain of the shoulder.

Objectives : This study aimed to investigate the correlation between fear-avoidance beliefs and neck pain/neck disability caused by traffic accidents. Methods : We surveyed 52 patients who were injured in traffic accidents. The patients completed baseline measures of pain, disability, fear-avoidance beliefs according to the visual analogue scale(VAS), neck disability index(NDI) and a fear-avoidance beliefs questionnaire (FABQ). At the end of medical treatment, VAS and NDI were reassessed. In order to determine the relationship between FABQ(including its subscales), change of VAS and NDI, Pearson correlation coefficients were used. To examine the accuracy of previously reported cut-off scores, we classified the patients into low and high groups and analyzed the change of VAS and NDI. The relationship was measured by Mann-Whitney U-test and a student's T-test. Results : FABQ and its subscales(total, physical activity and work) were significantly correlated with final VAS and NDI. FABQ-T showed low significant negative correlation with change of NDI. Previously reported cut-off scores did not show a statistical significance in this study Conclusions : This study suggests that screening for fear-avoidance beliefs may be useful for identifying patients at risk of prolonged pain after traffic accidents.

Neck pain was commonly experienced by both adolescents and adults. The neck disability index(NDI) was the most commonly used self-report measure for evaluating status in neck pain. The objective of this study is to research the prevalence of the NDI in their 20's of college students in department of physical therapy. The data were collected from the NDI questionnaire of college students(males: 229, females: 405) for functional disability measures. Statistical analysis was carried out with SPSS 12.0 program, which was used for descriptive statistics, independent samples test and Pearson correlation analysis. The results were : First, 'headache' item was showed 'the highest prevalence' in second choice demonstrating the neck disability and 'pain intensity' in third choice. Second, female(46.4%) was higher distribution than male(36.3%) on score, percentage and grade of NDI(p<0.05). Third, the NDI grade was investigated that it is composed of 'no disability(63.8%)', 'mild disability(35.4%)', and 'moderate disability(0.9%)' in male and 'no disability(53.6%)', 'mild disability(44.7%)', 'moderate disability(1.5%)' and 'severe disability(0.2%)' in female. Fourth, there was a statically significant relationship between NDI grade and NDI items(p<0.05). These results have specific meaning as future clinical and epidemiological studies. Also, it is needed to education and preparation on prevention and management of neck disability among college students.

The purpose of this study is to observe the effectiveness of the Korean medical complex treatments for functional dyspepsia (FD). And we observed NDI-K (Nepean dyspepsia index-Korean version) and algometer on acupoints to confirm the treatment effectiveness. In this retrospective study, we investigated 77 patients with FD symptoms who admitted to 00 Korean Hospital for 2 weeks from April 14, 2020 to March 31, 2021. All patietns were treated with herbal medicines, acupuncture, pharmacopuncture, moxa treatment, aroma therapy, So-jeok and So-jeok II therapy. On the day of admission and discharge, NDI-K, algometer on acupoints (CV12, CV10, ST25, ST27, SP14) were examined twice. Among the NDI-K values, all 14 items except for poor breathing were decreased statistically significantly. The algometer values were increased statistically significantly in all acupoints (CV12, CV10, ST25, ST27, SP14). These results suggest that Korean medical treatment can be useful in the treatment of FD.

Purpose: The purpose of this study was to investigate the effects of neck patterns in proprioceptive neuromuscular facilitation (PNF) for neck movement and the neck disability index (NDI) among adults with forward head posture. Methods: Thirty-nine subjects were randomly assigned into two groups. Subjects in the proprioceptive neuromuscular facilitation exercise group (PNFG, n = 20) received 20 minutes of PNF neck pattern (flexion-Rt. lateral flexion-Rt. rotation followed by extension-Lt. lateral flexion-Lt. rotation) 3 times weekly for 4 weeks. Outcomes were measured using absolute rotation angle (ARA), anterior weight bearing (AWB), range of flexion and extension motions (RFEM), and neck disability index (NDI) methods before and after the 4-week intervention period. Results: There were significant effects for the PNFG, pre- and post-intervention, in ARA, AWB, RFEM, and NDI. There were significant differences in ARA, AWB, RFEM, and NDI compared with CG. Conclusion: The results of this study suggest the PNF neck pattern could be beneficial for adults with forward head posture.

Purpose: The purpose of this study was to examine the functional category, the item structure and the model-data fit of the neck disability index (NDI) of neck pain subjects by performing a Rasch rating scale analysis. Methods: The data was obtained from the assessments of 71 college students (males: 27, females: 44) with neck pain. The data of the NDI was applied to the Rasch's rating scale model to estimate the difficulty of items, the goodness-of-fit of each item, the separation reliability and index, and the rating scale. Results: The 'sleep' item showed misfit and nine items were founds to be fits for self-reporting of disability due to neck pain. The most difficult item of the remaining 9 items was 'work' and the easiest item was 'headache'. The transformation formula score=(logit score+7.10)/(7.10+0.11)$\times$100. The 6 response levels of the NDI were validated according to the structure of the rating scale. The item and subject reliability of the separation reliability was 0.97 and 0.85, respectively. Conclusion: We proved that the NDI for self-reporting of disability of daily activities due to mild neck pain was valid and reliable. This study suggests that individuals with mild neck pain may be assessed by using the modified NDI that does not include the 'sleep' item in the 10 items of NDI.
