TY - JOUR T1 - Development of the Concussion Recovery Questionnaire: a self-report outcome measure of functional status following concussion (PhD Academy Award) JF - British Journal of Sports Medicine JO - Br J Sports Med SP - 573 LP - 574 DO - 10.1136/bjsports-2020-102275 VL - 55 IS - 10 AU - Jacqueline Josee van Ierssel Y1 - 2021/05/01 UR - http://bjsm.bmj.com/content/55/10/573.abstract N2 - I employed an iterative, patient-centred approach to develop a concussion-specific functional status measure.While most adults fully recover from concussion, at least 15% exhibit ongoing symptoms including headache, fatigue and difficulty concentrating for years resulting in high degrees of disability.1 Since no objective biomarker exists for concussion, self-reported symptom burden is the most commonly reported recovery measure, along with cognitive function, balance and exercise tolerance in terms of frequency, duration, difficulty or agreement level. Clinical tests of cognition and balance often appear normal beyond the acute phase. Symptoms are non-specific and commonly present in other conditions such as depression, anxiety and post-traumatic stress disorder.1 Persons with concussion often manage their symptoms by limiting provocative activities and social participation. A low symptom score may thus reflect reduced life activities rather than functional recovery. Prior to my research, no concussion-specific measure of functional status existed. I conducted this research to address a gap in clinical tools … ER -
