Why do we encounter studies with older versions of the Oswestry Disability Index? Awareness of researchers about the version updates and the lifespan of older versions.

BACKGROUND: The Oswestry Disability Index (ODI) is a common outcome-measure used for assessment of spinal disorders with three officially updated versions. However, there are recently published articles that still use ODI-1.0. This suggests the existence of a block on information flow between developers and end-users. OBJECTIVE: To investigate the articles with missing citation to the latest ODI version, to calculate the life span of previous ODI version and to investigate the existence of a block on information flow. METHODS: PMC-PubMed citation dataset is analyzed by CNA and text processing methods. RESULTS: The most important finding of this study is that there is no block on information flow between developers and users in terms of visibility in citations and full text access restrictions. Three different sub-networks are identified between ODI-1.0 and ODI-2.0 articles. 14% (165) of articles have citation to ODI-1.0 and ODI-2.0 version-articles. The time limit that is required for the new ODI version to become dominant in the literature is between 4 and 9 years. CONCLUSION: There is a missing citation problem in the ODI literature which is not a result of a block on information flow between developers and end-users.

The evaluation of clitoral blood flow and sexual function in elite female athletes.

INTRODUCTION: Clitoral blood flow measurements using clitoral color Doppler ultrasound have been performed with increasing frequency either in order to assessment of female sexual function/dysfunction. The trials to evaluate the sexual function in healthy subjects, especially in the subgroup of female elite athletes, are limited. AIM: The aim of the study was to evaluate whether elite female athletes and sedentary healthy females differ in their clitoral blood flow and sexual function as an expression of their physical fitness status. METHODS: Twenty-five female elite athletes (Group I) and healthy female subjects (Group II) were enrolled as volunteers in the study. All women were instructed to complete the Female Sexual Function Index (FSFI) questionnaire. Each subject underwent high definition color Doppler ultrasonography to measure the clitoral blood flow parameters. Main Outcome Measures. The effect of physical activity on clitoral blood flow and sexual life in women. RESULTS: Mean age, mean age of menarche, mean marriage age, and body mass index were similar for both groups. In Group I, the mean peak systolic velocity and end-diastolic velocity were higher than those of Group II, whereas the mean RI was similar for both groups. There were statistically significant differences for total FSFI score and all domain scores, except desire domain, between both groups. CONCLUSION: In elite female athletes as compared with sedentary healthy females, better clitoral blood flow and better sexual function were demonstrated. Therefore it seems superior physical fitness correlates with better sexual function.

The most cited and co-cited COVID-19 articles: Knowledge base for rehabilitation team members.

BACKGROUND: The COVID-19 outbreak pandemic is a situation without a tested action plan. Rehabilitation team members have been called for duty with new responsibilities in addition to their conventional roles in the healthcare system. The infectious disease specialists are updating the knowledge base in limited time in clinical settings. The number of articles in PubMed grows at an increasing rate. OBJECTIVE: The purpose of this study is to identify core COVID-19 articles by citation and co-citation network analysis in the PMC subset of PubMed. METHODS: Citation and co-citation network analysis methods were used to identify core articles and knowledge base. RESULTS: COVID-19 terms query retrieved 15,387 articles in PubMed. These articles formed a citation network with 6,778 articles and 25,163 PMC-PubMed citations. The main article cluster in the co-citation network consists of 2,811 articles and 78,844 co-citations. CONCLUSIONS: The number of COVID-19 articles in PubMed is increasing at a very high rate. Citation and co-citation network analysis are advantageous techniques to identify knowledge base in a scientific discipline. These techniques may help rehabilitation specialists to identify core articles efficiently.

Relatively short term test re-test reliability of Neck Disability Index by long term test re-retest reliability method of Oswestry Disability Index in healthy office workers.

BACKGROUND: Assessment of local condition specific outcome measures in combination to obtain an idea about the disability status of the whole spine is a conventional method. Oswestry Disability Index (ODI) and Neck Disability Index (NDI) are two outcome measures used together. Test re-test reliability of ODI in healthy subjects has clinical importance and the test re-test reliability of NDI may have clinical significance. OBJECTIVE: The purpose of this study is to investigate the test re-test reliability of the NDI by using long-term test re-test reliability method of ODI on healthy office workers. METHODS: Participants who have no chronic neck pain history were included in the study. Subjects were assessed by the Turkish-NDI (e-forms) on 1st, 2nd, 4th, 8th, 15th, 30th days. 49 (20 female, 29 male) of 106 participants (57 female, 49 male) completed the study. Kolmogorov-Smirnov and Friedman tests were used. RESULTS: The difference between median score of each day (χ= 9.275, p > 0.05) was neither statistically nor clinically significant. CONCLUSIONS: NDI has test re-test reliability in healthy subjects over a 1-month time interval and the test re-test reliability is also valid in cases where both questionnaires are used in combination in this time interval.

Long term test-retest reliability of Oswestry Disability Index in male office workers.

BACKGROUND: The Oswestry Disability Index (ODI) is one of the most common condition specific outcome measures used in the management of spinal disorders. But there is insufficient study on healthy populations and long term test-retest reliability. This is important because healthy populations are often used for control groups in low back pain interventions, and knowing the reliability of the controls affects the interpretation of the findings of these studies. OBJECTIVE: The purpose of this study is to determine the long term test-retest reliability of ODI in office workers. METHODS: Participants who have no chronic low back pain history were included in study. Subjects were assessed by the Turkish-ODI 2.0 (e-forms) on 1st, 2nd, 4th, 8th, 15th, 30th days to determine the stability of ODI scores over time. The study began with 58 (12 female, 46 male) participants. 36 (3 female, 33 male) participated for the full 30 days. STATISTICS: Kolmogorov-Smirnov and Friedman tests were used. Test-retest reliability was evaluated by using nonparametric statistics. All tests were done by using SPSS-11. RESULTS: There was no statistically significant difference among the median scores of each day. (χ= 6.482, p >  0.05). CONCLUSION: The difference between median score of the days with 1st day was neither statistically nor clinically significant. ODI has long term test re-test reliability in healthy subjects over a 1 month time interval.
