Hocoma’s Lokomat is a driven gait orthosis that automates locomotion therapy on a treadmill and improves the efficiency of treadmill training. The Lokomat improves the therapy outcome by providing highly intensive, individualized training in a motivational environment of constant feedback.

Locomotion therapy supported by an automated gait orthosis on a treadmill has shown to be an effective intervention for improving over-ground walking function caused by neurological diseases and injuries in many cases. The Lokomat system assists walking movements of gait-impaired patients and is used to improve mobility in individuals following stroke, spinal cord injury, cerebral palsy and multiple sclerosis as well as other neurological diseases and injuries. The LokomatPro has been on the market since 2001 and has been a crucial improvement in the art and science of locomotion therapy. The product is based on research and development activities at the Balgrist University Hospital.

We are proud to present a new version of the LokomatPro as of March 2011 (depending on national registration procedures). This new version of the LokomatPro features a new and more compact design and is equipped with the Augmented Performance Feedback and a touch screen as a standard. In the future, upgrading options (e.g. additional degrees of freedom at the hip joint, sophisticated control strategy, higher gait speed) will extend the LokomatPro as a sophisticated gait training device that supports the therapists and the patients in reaching their therapy goals.

  • Features and Function

    Lokomat®Pro
    The LokomatPro consists of the robotic gait orthosis, the body weight support system Levi and a treadmill. The patient’s legs are guided on the treadmill according to a pre-programmed physiological gait pattern. The computer controlled guidance allows individual adjustments of different gait parameters.

    Automated locomotion therapy on a treadmill
    The LokomatPro utilizes high quality computer controlled motors (drives) which are integrated in the gait orthosis at each hip and knee joint. Force transducers at the joints accurately measure the interaction between the patient and the LokomatPro. The drives are precisely synchronized with the speed of the treadmill. This sensitive system assures a precise match between the speed of the gait orthosis and the treadmill.

    Physiologic gait pattern
    Hip and knee joint angles are controlled in real time by software to achieve a physiologically meaningful gait pattern. Each of the four joints is constantly monitored by the LokomatPro software to ensure that they are precisely held to the predefined gait pattern.

    Individual adjustments for patients comfort
    The LokomatPro robotic gait orthosis is adjustable to the patient’s anatomy. Hip width, length of upper and lower leg, size and position of the leg cuffs can be conveniently and individually adjusted assuring a comfortable gait training.

    Convenient handling
    A user interface allows the therapist to easily operate the LokomatPro and adjust training parameters on a touch screen to suit the individual patient’s needs at any point during a training session. Patients in a wheelchair can be escorted on a ramp onto the treadmill and can be easily set up in the LokomatPro. The orthoses of the LokomatPro can be moved out of the way from the treadmill, making it possible to easily switch from automated to manual therapy, if needed.

    Augmented Performance Feedback
    The Augmented Performance Feedback of the LokomatPro provides motivating, challenging and instructive functional feedback in virtual environments. As virtual reality enhances the patient’s active participation during the robot assisted training, the Augmented Performance Feedback encourages and helps improving the patient’s compliance (for a publication list see “Literature”).

    Body weight support
    Body weight support systems are used for manually assisted and for automated treadmill training. Patients may be lifted out of the wheelchair and partially unloaded from their body weight. However, standard body weight support systems – like counterweight systems – do not provide a constant weight support for the patient due to the inertia forces of the counterweights. The weight carried by the patient is therefore subject to fluctuations.

    The LokomatPro includes the Levi, a body weight support system with superior functionalities and patient unloading possibilities. It facilitates patient handling and optimizes physiological gait training.

    • Promotes a more physiological gait through its new dynamic, low inertia suspension system which allows a precise unloading and a more physiological vertical movement of the patient.
    • Continuously adjustable body weight support facilitates training for children and lightweight patients.
    • Easy to operate: Automated patient lifting and unloading facilitates set-up and training.

    Lokomat options
    Optionally, the LokomatPro can be adapted for the training of small children with the specially designed Pediatric Orthoses.

    Lokomat upgrades
    Further upgrading options will be available for the new version of the LokomatPro in the future, e.g. additional degrees of freedom, sophisticated control, higher gait speed.

    Assessment Tools
    The Assessment Tools of the LokomatPro provide ongoing assessment of the patient’s motor functions and allow monitoring of the recovery progress and precise evaluation of the patient’s abilities. The LokomatPro offers the following tools for a convenient assessment of the main problems of neurologic patients:

    • L-WALK: Allows the clinician to compare the patient’s walking endurance over several training sessions. The patient’s walking activity is measured by force transducers integrated in the joints of the Gait Orthosis.
    • L-STIFF: Measures the mechanical stiffness of the patient’s joints while passively moving the legs in a specific pattern.
    • L-FORCE: Evaluates the isometric force generated by the patient while in a static position.
    • L-ROM: Offers the measurement of the range of motion used during a passive or active movement without support by the Lokomat drives.

    Orthopedic Storage
    The Lokomat portfolio provides two orthopedic storage solutions, which allow ergonomic handling of the orthopedic material and faster training preparation. The orthopedic storage is an optional accessory to the Lokomat and is available for the LokomatNanos and the LokomatPro.

    The Orthopedic Storage offers the following advantages:

    • Safe and easy storage
    • Easier training preparation
    • Faster patient set-up
    • More ergonomical handling of orthopedic material and orthoses

    As a standard feature of the new version of the LokomatPro, the Augmented Performance Feedback enhances the patient’s active participation with motivating, challenging and instructive functional feedback in virtual environments. During the gait training, the patient can move through various engaging virtual environments while solving different exercises .

    This encourages and helps to improve the patient’s compliance. The exercises range from tasks in which the patients have to collect randomly distributed objects in the virtual environments to tasks in which they have to avoid certain objects and tasks that combine the two. The difficulty level can be adapted for each exercise according to the patient’s needs and abilities as well as the individual therapy progress.
