Blood flow restriction (BFR) therapy is a brief and partial restriction of venous outflow of an extremity during low load resistance exercises. It is a safe and effective method of improving strength in healthy and active individuals, recovering from orthopedic pathologies and procedures. This prospective, randomized study will look at the implications this form of treatment has on the rehabilitation of Achilles injuries.

Inclusion Criteria:

• Diagnosed with Achilles Injury
• Must be at least 18 years of age and younger than 65 years of age
• Intention to receive physical therapy as standard of care

Exclusion Criteria:

• Patients with intention to receive standard therapy and not the study therapy
• Patients with impaired circulation, peripheral vascular compromise, previous revascularization of the extremity, or severe hypertension
• Younger than 18 years of age or older than 65
• Legally incompetent or mentally impaired (e.g. minors, Alzheimer's subjects, dementia, etc.)
• Any patient considered a vulnerable subject
