Achilles Tendon Ruptures

Acute Achilles tendon rupture (ATR) is an injury that is commonly associated with complications, such as blood clotting, muscle loss and tendon lengthening, all of which affect the long-term outcome and return to sports. These complication are related to the treatment of ATR with lower leg immobilization in a boot. The investigators aim to demonstrate that an intervention with calf neuromuscular electrical stimulation (C-NMES) during leg immobilization after ATR can 1) reduce blood clots, 2) lower the degree of muscle loss, 3) decrease tendon lengthening and 4) improve long-term outcome.
