In 2013, the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O) was developed to record the magnitude, symptoms and consequences of overuse injuries in sport. Shortly afterwards, a modified version of the OSTRC-O was developed to capture all types of injuries and illnesses—The Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H). Since then, users from a range of research and clinical environments have identified areas in which these questionnaires may be improved. Therefore, the structure and content of the questionnaires was reviewed by an international panel consisting of the original developers, other user groups and experts in sports epidemiology and applied statistical methodology. Following a review panel meeting in October 2017, several changes were made to the questionnaires, including minor wording alterations, changes to the content of one question and the addition of questionnaire logic. In this paper, we present the updated versions of the questionnaires (OSTRC-O2 and OSTRC-H2), assess the likely impact of the updates on future data collection and discuss practical issues related to application of the questionnaires. We believe this update will improve respondent adherence and improve the quality of collected data.

To describe changes in health-related quality of life in people with lower limb amputation, from time of amputation to 18 months, taking into consideration the influence of age and walking distance. In addition, quality of life for people with amputation is compared with the Dutch population norm values. Multicentre, longitudinal study. All people undergoing first amputation: 106 were referred, of whom 82 were included, mean age 67.8 years (standard deviation; SD 13.0), 67% men. A total of 35 remained in the study at 18 months. Dutch language RAND-36 questionnaire (Research and Development Corporation measure of Quality of Life) was completed at time of amputation, 6 and 18 months after amputation. Over time, a significant improvement was seen in physical function, social function, pain, vitality, and perceived change in health (all p < 0.001). Subjects over 65 years of age had a poorer outcome compared with people <65 years for physical function only (p < 0.001). Walking distance was associated with improved scores in social function (p = 0.047). Quality of life improved significantly in 5 of 7 domains investigated; most change occurred in the first 6 months. Physical function remained well below population norm values. Different domains may be affected in different ways for older and younger age groups, but this requires further research.
