All running-related injuries come down to a single premise, training load vs physiologic capacity. While basic examination techniques such as ROM and MMT are a first step they cannot fully measure the physiologic capacity of a runner to tolerate running loads. To fill this gap a test item cluster of evidence-based assessments can be deployed to pinpoint deficiencies in strength, strength endurance, power, and motor control. This allows clinicians to make data-driven decisions to address these impairments and track change over time. This data may even determine when an injured runner is ready to resume running.
