Implements an evidence-based protocol derived from a systematic review of seven studies (Li, 2026; <doi:10.17605/osf.io/kvuf6>), 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.https://github.com/r-universe/guangl10/actions/runs/26748027674Wed, 27 May 2026 21:07:02 GMTPPCSexRx0.1.0successhttps://guangl10.r-universe.devhttps://github.com/guangl10/ppcsexrxPPCSexRx.RmdPPCSexRx.htmlPPCSexRx: Evidence-Based SSTAE Support With Tiered Clinical Safety2026-05-12 21:29:192026-05-19 21:04:18
