Q. Is ZeroG-Lite registered with the FDA?
Yes, ZeroG-Lite is listed with the FDA under Aretech’s registration number (3007797030).
Q. Can ZeroG-Lite training be billed to healthcare providers and Medicare?
Yes, ZeroG-Lite gait training is normally billed using standard gait training codes.
Q. What is the difference between ZeroG-Lite and other treadmills with offloading capabilities?
ZeroG-Lite is a high-tech robotic gait training system that provides dynamic body-weight support or static support. ZeroG-Lite’s robotic unloading system provides precise body-weight support by a specific number of pounds or percentage of weight while important training data is recorded in a database to track a patient’s recovery. The dynamic body-weight support allows the patient to perform walking lunges or squats and a chair may even be placed on the treadmill to practice sit-to-stand. Other treadmill systems may simply have a fall protection device, which doesn’t allow these dynamic vertical activities or capture training information from the session.
Q. What is the heaviest patient that can use ZeroG-Lite?
The heaviest patient that can use ZeroG-Lite is 400 lbs.
Q. How much body-weight support can ZeroG-Lite provide a patient?
ZeroG-Lite has two unloading modes. In static body-weight support, the position of the patient is fixed so they are restricted from moving downwards. ZeroG-Lite can provide up to 400 lbs of static support. In dynamic body-weight support, the patient can move freely up and down while the level of support stays constant. ZeroG-Lite can provide between 10-200 lbs of dynamic support.
Q. How fast can patients walk in ZeroG-Lite?
The maximum treadmill speed is 5 mph in both the forward and reverse directions.
Q. What data does ZeroG-Lite record from each training session?
The ZeroG-Lite software contains a SQL database that is password encrypted. For each session, the software records the distance walked, training minutes, falls prevented, incline, and the minimum and maximum body-weight support.
Q. What type of treadmill comes with ZeroG-Lite?
ZeroG-Lite comes standard with a Woodway PPS treadmill. As the industry leader in treadmills, the Woodway PPS consists of a 27” wide, 68” long slat-belt surface that provides the highest level of comfort and durability of any treadmill.
Q. How can ZeroG-Lite be useful for research?
For researchers who require more than clinical measures, ZeroG-Lite has a Researcher’s Toolkit. ZeroG-Lite records system level signals at 1,000 times per second. This is extremely useful during gait studies when the precise rope force and rope angle need to be known throughout the gait cycle. For researcher’s using external devices such as EMG systems and force plates, ZeroG-Lite’s electronics has an auxiliary input channel (BNC connector) that allows the synchronization of these devices with the ZeroG-Lite data.
Q. What is the elevation range of the treadmill on ZeroG-Lite?
The treadmill inclination goes up to 15% in increments of 1%. This is helpful because patients can practice walking uphill, or if the belt speed is reversed and the patient faces the back of the treadmill, they can practice walking downhill.
Q. Does the treadmill come with therapist seating?
Yes, ergonomic seating comes on both sides of the treadmill. The height of each seat can be adjusted and the seat pivots towards or away from the belt. The position along the side of the treadmill can also be adjusted. Complementing the therapist seats are footplates, which allow the therapist to brace themselves when manually assisting a patient during treadmill ambulation.
Q. Does ZeroG-Lite come with a ramp and landing for the treadmill?
Yes, we include a ramp to help transfer patients to and from the treadmill. The landing is important for two reasons. First, it allows patients to safely park their wheelchairs on a flat surface and then transfer to the treadmill surface. Second, the ramp can be positioned straight off the back of the landing or off one side which is helpful for positioning ZeroG-Lite in facilities with limited space.
Q. What safety measures does ZeroG-Lite have?
ZeroG-Lite includes redundant sensors throughout the system that crosscheck critical signals, software monitoring at 1,000 times per second, a hardwired emergency stop, and a back-up emergency battery in the event of a building wide power outage. ZeroG-Lite is certified to IEC60601-1, 3rd Edition for Medical Device Safety and compliant with electromagnetic emissions and immunity testing EN6060101. There has never been a reported adverse event to a therapist or patient using ZeroG-Lite.
Q. How long does it take to set a patient up?
The average patient can begin a training session in less than 5 minutes. First, they are secured into a harness, assisted up the ramp if needed and then the harness is attached to the ZeroG-Lite spreader bar. The settings are selected from the computer and training can then begin.
Installation and Facility Facts
Q. What are the ceiling height requirements in order to install ZeroG-Lite?
The minimum ceiling height, from floor to the drop down tiles is 10 feet. If the height is less than 10 feet, then a 3’ x 5’ section above the treadmill may be recessed where the robotic unloading system is mounted within. With this easy modification to the ceiling, ZeroG-Lite can fit into buildings with low ceilings without an issue. Aretech can recess the ceiling for additional installation fees.
Q. How is the robotic unloading system attached to the ceiling?
Most facilities have concrete floors or I-beams as their main structure, which are hidden by the drop down ceiling tiles. The top plate of the unloading system is mounted directly to the main structure of the building (e.g. the concrete or I-beams), making it very strong. The mounting system was designed by a licensed structural engineer and meets all building codes.
Q. What kinds of substrate can ZeroG-Lite be mounted to?
ZeroG-Lite can be installed into buildings that have steel reinforced concrete, steel corrugated pan or I-beams. For the first two kinds of substrate, we install Hilti expansion anchors into the concrete and then suspend the unloading system from these anchors. For I-beams, we simply clamp to the I-beams. A licensed structural engineer has designed all of our installation methods. If the facility does not have one of these substrates, contact us and we can work with our engineers to develop a custom installation method.
Q. How long does it normally take to install ZeroG-Lite?
On average, it takes about 1.5 days to install the ZeroG-Lite system in the customer’s facility. We require the area where the system will be installed is closed off for safety reasons. We work closely with the clinical staff to try and minimize the inconvenience to the staff during the installation process.
Q. Can installations be done over a weekend?
Yes. We are happy to install the system over the weekend so that we do not interrupt therapy sessions.
Q. Does the price of ZeroG-Lite include installation?
The price of ZeroG-Lite includes the installation at the customer’s facility. However the included cost is for a typical installation in a facility that has steel reinforced concrete, steel corrugated pan or exposed I-beams. Additional installation costs may occur if any of the following is true:
- The building has asbestos or other hazardous materials
- The installation requires a custom installation consisting of heavy steel supports
- The installers have restricted access to the space where the system will be installed (e.g. less than 12 hours per day)
- The location where ZeroG-Lite will be installed is changed requiring modifications (based on site survey) and/or change in installation method (e.g. different substrate, presence of hazardous materials, etc.)
- Information provided to Aretech prior to the installation is incorrect which delays the installation beyond 30 hours
- Delays due to facilities personnel halting an installation who:
- Request information that should have been asked for prior to installation (e.g. details of installation methods, documentation, etc.)
- Specify facility policies that are not consistent with the information provided in the ZeroG-Lite Installation Questionnaire
During the site-survey of the customer’s facility, we will determine what, if any, additional installation costs will occur. These additional costs will be included in the quotation.
Q. Can ZeroG-Lite be installed in buildings that have asbestos?
Yes, our installers have completed asbestos training from an OSHA certified center. The customer is expected to seal off the room and have an asbestos abatement team available during the installation.
Q. Are there other options available where the unloading system does not connect to the ceiling?
Yes. Aretech will work with customers on a custom installation for ZeroG-Lite which may include a frame or boom. These installations may incur additional installation fees.
Q. When does training occur?
After the system is installed and tested in a customer’s facility, Aretech will schedule therapist training. ZeroG-Lite onsite training normally takes 4-6 hours and is by a therapist with years of experience treating patients with ZeroG.
Q. What other requirements are necessary to install ZeroG-Lite?
The system requires a 208 VAC, 15 amp outlet to run the system and two standard 110 VAC outlets for the user-interface computer and the wireless router. For a single-belt treadmill, a 120 VAC, 20 amp dedicated circuit is required and a 208 VAC, 20 amp dedicated circuit is needed for a split-belt treadmill.
Q. How often does ZeroG-Lite need to be serviced?
After ZeroG-Lite is installed, quarterly checks need to be done on the system by someone at the customer’s facility. Then, if the customer elects to purchase a service contract, a certified Aretech technician will come to the customer’s facility every 2 years to perform preventative maintenance on the system.
Q. How much does the service contract cost and what does it include?
From the date of installation, ZeroG-Lite comes with a 2-year warranty that includes telephone technical support (M-F, 8 am – 8 pm EST), onsite visits that are necessary to repair the system, replacement parts and labor. Starting at month 24, customers may purchase a bi-annual service contract to cover the next 2 years. The service contract includes:
- A certified Aretech technician comes to the customer’s facility and performs comprehensive servicing and inspection of the ZeroG-Lite system.
- Unlimited telephone technical support (M-F, 8 am – 8 pm EST).
- Free software upgrades on the user interface, wireless interface and control system.
