An Achilles tendon rupture is a serious injury that occurs when the tendon that connects the lower leg to the heel bone is completely or partially severed. It often causes sharp pain in the lower leg and limits the ability to walk and move. The most common cause of Achilles tendon rupture is sudden stress or trauma, such as a sudden jolt or excessive strain on the tendon. Treatment may include conservative methods, such as casts, orthotics and physiotherapy, or surgery, depending on the severity of the injury. Recovery from an Achilles tendon rupture can be lengthy and requires a professionally guided rehabilitation process to restore functionality and strength to the foot and ankle. Physiotherapy after a complete rupture of the Achilles tendon plays a key role in the recovery process and restoring the functionality of the patient. This injury, which often occurs in athletes and active individuals, requires a careful and gradual approach to rehabilitation. The initial phase of rehabilitation after an Achilles tendon rupture usually involves immobilizing the foot in a cast or orthosis to ensure healing of the tendon. After that, physiotherapy procedures are gradually introduced to strengthen the muscles of the lower leg and foot, re-establishing the strength and balance of the muscles, which is crucial for the stability and functionality of the ankle. During rehabilitation, the physical therapist will also work to improve the range of motion in the affected ankle and lower leg. Other physiotherapy techniques such as the application of physical factors are gradually introduced to reduce inflammation and promote healing. An important aspect of rehabilitation after Achilles tendon rupture is the patient's gradual return to sports or daily activities. The physiotherapist will work on functional training to ensure that the patient can safely carry out their usual activities without the risk of re-injury.
