Background and Objectives: Chronic neck pain in various ages is one of the important causes of occupational disability which has imposed huge costs on health services. Therefore, developing a valid and reliable instrument to obtain information about patients with neck pain seems necessary. The present study was conducted to examine the psychometric properties of COMI-Neck questionnaire in Iranian patients with chronic neck pain.
Methods: In this study, in order to examine reliability (test-retest and internal consistency), the Persian version of The Core Outcome Measures Index for the neck (COMI-Neck), was completed using convenience sampling method among 100 patients with chronic neck pain attending rehabilitation clinics in Karaj city. In order to examine validity, FRI, NDI and SF-36 questionnaires were also completed by participants. Internal consistency, reliability, discriminate validity and construct validity were analyzed using SPSS 20 and statistical tests.
Results: The ICC test results for scores of 5 indices including pain, daily activities, adaptability to existing symptoms, quality of life, recreational and social activities in COMI-Neck, showed that very high validity of the questionnaire with Cronbach’s alpha of 0.89. There was strong correlation between the total score of COMI-Neck and the total score of FRI (P<0.05). Also, a strong correlation existed between the total score of COMI-Neck and NDI total score (P<0.05). Strong and reverse correlations were observed between score of all scales of COMI-Neck and the total score of SF-36 (P<0.05).
Conclusion: The Persian version of The Core Outcome Measures Index for the neck (COMI-Neck) showed good validity and reliability in evaluation of outcome measures among Iranian patients with chronic neck pain.

Background and Objectives: The short and long-term effects of Kinesio tape on pain and quality of life (functional status) in patients with knee osteoarthritis were investigated.
Materials and Methods: Forty-seven patients with knee osteoarthritis were randomly allocated into Kinesio tape and Sham Kinesio tape groups. The assessments were performed at the baseline, 30 minutes after the initial Kinesio tape application, 3 days after the fifth Kinesio tape application and 1 week later. The quality of life (functional status) of the patients was evaluated using the Western Ontario and McMaster Universities Osteoarthritis Scale (WOMAC). The pain level was measured using the visual analog scale (VAS).
Results: In both groups, the mean of the rest pain, activity pain score, and WOMAC score decreased, but there were no significant differences between groups for both VAS and WOMAC scores (P˃0.05). Also, there were no significant differences between groups during the follow up assessment.
Conclusion: According to the results, it may be concluded that there were no beneficial effects between Kinesio tape and sham tape on pain and on the quality of life in patients with knee osteoarthritis.
