Researcher teaching patient to walk again, using KineAssist. The harness moves with her, unless she loses balance, then the harness catches her before she can fall.

For the last decade, researchers at the Rehabilitation Institute of Chicago and Northwestern University have worked together with engineers at HDT Robotics to create a completely new type of therapy system for gait and balance recovery. This system, called the KineAssist-MX (Mobility eXtreme), provides clinicians with evidence-based tools and treatment guidelines to get patients back into the community, moving with greater confidence and more capability than can be achieved using other therapy approaches. The system provides unobtrusive support to patients, allowing them to walk on their own, or with variable levels of support. Patients can constantly challenge themselves, and even lose their balance, without any risk of falling. The result is a faster and more complete recovery. The research supporting the system has been presented both nationally and internationally.

As our clinical partners have discovered, the KineAssist-MX Walking & Balance system offers unique benefits to patients and their care providers at Rehabilitation Hospitals, Assisted Living Facilities and Skilled Nursing Facilities.

The KineAssist-MX can be used anywhere patients need to train to improve their gait and balance abilities. It is also appropriate for joint replacement rehabilitation and cardio-pulmonary stress testing where the patient is not capable of completing a traditional stress test. The KineAssist-MX can provide variable resistance, increasing the effort required by the patient to walk or perform other challenging tasks.

Key Features

  • Ability to safely challenge patients in real life environments, such as over ground walking, step climbing, standing balance and dynamic balance therapy
  • Efficient use of clinician’s time
  • Protect patients from the consequences of losing their balance, which builds confidence in their abilities while they increase strength and stamina
  • Easily adapts to the environment and integrates into a wide range of existing practice settings
  • Provides objective, standardized outcomes data
  • Treadmill surface moves in direct response to the user’s intention
  • Scientifically-tested, challenge-based training protocols
  • Immediate fall recovery for resumption of training
  • Combined intervention protocols incorporated in a single session
  • Body-weight is supported at the hip, allowing for a natural gait without any mechanical interference
  • Novel force-field environments
  • Provides ability to impose perturbations, in order to challenge patient’s balance and recovery
