The provided Persian version of FABQ is a reliable and valid measurement and further research into its use as a diagnostic and prognostic tool is warranted. Development of this questionnaire will be useful for comparability between Persian and English language studies and facilitates an international collaboration in this field.

Background:Low Back Pain (LBP) is one of the most prevalent causes of disability not only in the general population but also in athletes. Despite a large number of self-reported back specific disability questionnaires, there is no specific, well documented, outcome measure for athletes suffering from back pain.Objectives:This study aimed to identify the main descriptive themes representing functional disability in athletes due to LBP.Patients and Methods:We conducted a qualitative study using in-depth interviews to characterize the experiences of athletes with LBP. Twenty athletes with LBP were recruited and the main descriptive elements of their LBP related disability were extracted. Then a preliminary questionnaire using these themes was proposed.Results:The main disability indicators were pain intensity; stretching exercises, strengthening exercises, sport specific skills, back range of motion (ROM), sitting, walking, sleep patterns, self-care, and recreational activities, fear of pain and avoidance behavior, and changes in sexual activity.Conclusions:The findings of this study suggest that apart from non-sports items, some sport related items should be included in the assessment of LBP disability levels in athletes. Our results have also been organized as a preliminary LBP disability questionnaire for athletes.

This study has shown that injection is a more effective method for the administration of BTX-A, though iontophoresis can also be considered a non-invasive and painless method in some patients.
