THERY takes over gait training on crutches


Therapists can schedule training according to patients' needs. Patients can register on the robot and perform self-training around the clock.The robot actively corrects the patient's gait and documents the training. Therapists can check the results.

Use after surgery on the lower extremities, for example:

  • total hip arthroplasties (THA), total knee arthroplasties (TKA), femur fractures etc.
  • corrective osteotomies
  • cartilage lesions, injuries of the muscle-ligament apparatus, etc.

Therapy approach - Patients benefit from robot-assisted gait training on crutches by:

  • commitment due to fixed dates for self-training with the robot
  • feedback during self-training
  • improvement of knee-range-of-motion*
  • improvement of walking speed*
  • higher motivation for self-training**

In the future, the robot’s fields of application will also be expanded for third-party providers. The mode of operation resembles a smartphone on wheels.
