Package: PPCSexRx Type: Package Title: Prescribe Sub-Symptom Exercise for Adolescent Concussion Version: 0.1.1 Authors@R: person("Guang", "Li", email = "contact@guanglab.org", role = c("aut", "cre"), comment = c(ORCID = "0009-0004-2807-9029", "Idaho State University")) Description: A clinical decision support system for sub-symptom threshold aerobic exercise (SSTAE) prescription in adolescents with persistent post-concussion symptoms (PPCS). Implements an evidence-based protocol derived from a systematic review of seven studies (Li, 2026; ), encoding safety screening, Buffalo Concussion Treadmill Test (BCTT)-guided heart rate prescription, session-level progress tracking, and evidence disclosure using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework into an open-source tool for athletic trainers and clinicians. Designed to support implementation in resource-limited settings where BCTT equipment may be unavailable. GRADE certainty of evidence: LOW. For clinician use only; not a substitute for clinical judgement.
