Industry Leading Gait and Balance Training System

ZeroG is a robotic body-weight support system that safely allows walking overground, functional activities, balance and fall prevention training in a ‘reduced gravity’ environment.  When using ZeroG, walking, TRiP perturbations, getting off the floor, sit-to-stand and other activities are performed safely without the risk of falling.

Dynamic Body-Weight Support

ZeroG can maintain a consistent level of body-weight support regardless of vertical movements. For example, if the amount of unloading is set to 20%, the patient will always feel 20% lighter even when going from a sitting to standing position.

Advanced Fall Protection

Falls are prevented by controlling the range of motion or by the rate of vertical descent. Therapists can also disable fall protection; however ZeroG will limit the patient’s rate of descent.  Each mode is selected depending on the patient’s needs and the activities being performed. Integrated fall cushioning helps soften the impact when a fall is prevented.

Robot Tracking

The ZeroG robot anticipates and reacts to the patient’s movements as they move along the track.  In ’Free Walk’ mode, the robot eliminates drag and allows for a smooth, natural gait.  For additional customization, ZeroG can be set to facilitate walking or resist the patient’s forward momentum.

Free Walk

The ZeroG robot automatically tracks patient movements with no drag.  This mode is commonly used for overground gait training.

Resistance

The ZeroG robot positions itself posterior to the patient.  This creates a ‘drag’ on the patient, allowing them to work on core strengthening and balance.

Facilitation

The ZeroG robot positions itself anterior to the patient.  This produces a slight bias force encouraging the patient to walk faster.

TRiP Perturbations

TRiP (Training Responses in Postural Rehabilitation) is a patented feature exclusive to ZeroG.  TRiP allows clinicians to safely apply perturbations using the ZeroG robot during walking or stationary activities.  Using TRiP, patients can practice balance and fall prevention techniques which are skills they can use back in the community.

Clinical Results

Various clinical studies have shown that patients achieve greater gains in mobility, balance and overall function when using ZeroG during inpatient physical therapy when compared to Standard of Care therapy.

Higher Gains in FIM – Acute TBI

Patients who used ZeroG during inpatient rehabilitation demonstrated improvements in total FIM scores that were 39 points higher than patients show participated in inpatient physical therapy but did not used ZeroG.

Anggelis E, et al.  NeuroRehabil. 2019;45(4):519–24

Following acute CVA, patients who used ZeroG during inpatient rehabilitation demonstrated improvements in total FIM score that were 10 points higher than patients who participated in traditional physical therapy but did not use ZeroG.

Improvements Following Acute CVA

Higher Gains in Berg Balance

Patients treated with ZeroG and TRiP achieved significantly higher gains in Berg Balance scores when compared to Standard of Care therapy.

ZeroG Track Layouts

The ZeroG track is customized to each space and can be configured with straight sections, curves, or an oval shape.

Accessories

Sprintex Slat-Belt Treadmills

Medical grade treadmill with a slat-belt walking surface.  Optional clinician seating can be added when manual assisted treadmill training is anticipated.

Robotic Trolley

Add an additional robot to train multiple patients simultaneously.  When one is not in use, place in Stealth mode to propel it away from the other.

Passive Static Trolley

A cost-effective addition to the ZeroG track to train higher level patients at risk for falling.

Heart Rate Monitor &

Pulse Oximeter

Measure SpO2 and heart rate during a training session and over time.  Set audio and visual alerts in the ZeroG software to help monitor patient vitals.

Crawling Accessory

Practice pre-gait activities with the crawling accessory.  The light-weight pulleys automatically re-direct the unloading forces from mid-back to the shoulders as patients move from quadruped to sitting to standing.
