Grade Two Hamstring Strain in a College Football Player: A Case Report

This case study explores the rehabilitation of a 20-year-old collegiate linebacker with a grade 2 Semitendinosus hamstring strain sustained during a sprinting activity. Following initial clinical assessment and diagnostic ultrasound, an aggressive, structured rehabilitation protocol was implemented, incorporating modalities such as blood flow restriction (BFR) and aquatic therapy. Traditional approaches to hamstring injuries were adapted with these additional interventions to accelerate recovery, enabling a return to play in nine days. The study highlights the potential use of BFR in early rehabilitation to achieve muscle activation with reduced load, suggesting its utility in shortening recovery time compared to standard hamstring injury protocols documented in the literature.
