Objective To explore patient-perceived activity limitations following concussion mapped to the International Classification of Functioning, Disability, and Health (ICF).

Design Prospective.

Setting Secondary schools in the United States.

Participants Fifty patients (41 males, 5 females, 4 missing, age=14.9±3.5 years) with a medically diagnosed sport-related concussion.

Interventions (or Assessment of Risk Factors) The Patient Specific Functional Scale (PSFS) was used to assess self-perceived limitations resulting from concussion. Activities were coded into and mapped to ICF domains, chapters and categories.

Outcome Measures The dependent variables were the PSFS patient-response categories, ICF domains, chapters, and categories. Descriptive analyses and frequencies were reported.

Main Results Patients listed 157 individual activities that were categorized into 28 patient-response categories. All (100%) responses were mapped to the ICF with most (75%, 21/28) fitting the activities and participation (AP) domain. Within the AP domain, most items mapped to the community, social, and civic life chapter (48%, 10/21), followed by learning and applying knowledge (14%, 3/21), and mobility (14%, 3/21). The most common categories mapped within the AP chapters were recreation and leisure (48%, 10/21), applying knowledge (14%, 3/21), and school education (9.5%, 2/21). Of the 25% (7/28) fitting body structures and functions, items primarily mapped to the mental functions (71.4%, 5/7) and sensory function and pain (28.6%, 2/7) chapters and to the specific mental functions (42.9%, 3/7) and sleep (28.6%, 2/7) categories.

Conclusions Adolescents self-identified post-concussion activity restrictions that impacted their perceived health status, primarily related to functional activities and social roles. The PSFS may complement impairment assessments to better manage patients post-injury.
