1. ME A ZERO ax PASSIVE ARETECH Overview Q What is ZeroG Passive ZeroG Passive is an easy to use system that provides patients the ability to safely practice overground walking and balance activities The patient s harness connects to the small ZeroG Passive trolley that glides smoothly along a ceiling mounted track This results in full protection against falls while maintaining its orientation above the patient Because the Passive trolley weighs less than 5 pounds and uses wheels with precision bearings it is nearly imperceptible to patients Q Is ZeroG Passive registered with the FDA Yes ZeroG Passive is listed with the FDA under Aretech s registration number 3007797030 Q How is ZeroG Passive different from the full ZeroG System ZeroG Passive provides only static body weight support and does not have any motors electronics or computers The therapist manually adjusts the Passive s harness straps in order to adjust the amount of tension the subject receives In addition as the patient walks ZeroG Passive moves along the track due to tension in the unloading ropes rather than being actively moved with a motor Conversely ZeroG is controlled through software by a therapist where the type of body weight support e g static vs dynamic as well as the trolley behavior can be adjusted with the press of a button on the computer Also the active trolley of ZeroG automatically moves the system as the subject walks and can cre2. a highly versatile gait rehabilitation tool that may be used by any patient population that could benefit from body weight support while performing locomotion or other weight bearing exercises including stroke traumatic brain injury spinal cord injury multiple sclerosis cerebral palsy orthopedic patients and amputees Q Can ZeroG Passive training be billed to health care providers and Medicare Yes ZeroG Passive gait training is normally billed using standard gait training codes Q What is the biggest patient that can use ZeroG Passive The largest patient that can use ZeroG Passive is 400 Ibs Q Since Passive is not motorized does the patient need enough strength to pull the trolley along Yes however because there is minimal friction in the trolley very little strength is required 2 Page ZERO A PASSIVE ARETECH Q How fast can patients walk in ZeroG Passive Since ZeroG Passive moves along the rail through tension in the straps that connect to the patient s harness there is no limit in movement speed Essentially ZeroG Passive can move as fast as the patient even if they run in the system Q How is the amount of tension adjusted in ZeroG Passive ZeroG Passive provides patients static body weight support during gait and balance activities The system is designed for easy adjustment of rope length and tension using ratcheting mechanisms Throughout a therapy session the rope tension can easily be adjusted depe
3. along the overhead track Also since there are no barriers between the patient and the therapist this truly encourages patient therapist interaction Installation and Facility Facts Q What are the ceiling height requirements in order to install ZeroG Passive The minimum ceiling height from floor to the drop down tiles is 8 feet If possible the optimal ceiling height is 10 feet Most hospitals will have a drop down ceiling below the main substrate such as concrete or I beams The maximum distance between the floor and the main substrate e g the concrete slab or I beams is 17 feet If the distance is greater than this the customer should consider a floor mounted free standing system Aretech will work with the facility to determine the proper installation method Q How is the system attached to the ceiling Most hospitals have concrete floors or l beams as their main structure which are hidden by the drop down ceiling tiles The track of ZeroG Passive is mounted directly to the main structure of the building e g the concrete or I beams making it very strong A licensed structural engineer designed the track mounting system which meets Federal building codes Q What kinds of substrate can ZeroG Passive be installed in We can install our system into buildings that have steel reinforced concrete steel corrugated pan l beams and even wood For the first two kinds of substrate we drive Hilti anchors into the concrete and then s
4. ape There is no maximum length for the ZeroG Passive track A 50 foot track is included in the price however additional lengths and or curves can be added for additional costs Tracks can be straight have curves or even be an oval or closed loop path 5 Page ZERO A PASSIVE ARETECH Q Is there a free standing option that is not mounted to the ceiling Yes we can mount the track on floor mounted gantries as well as booms that can be mounted off the walls Please contact us to discuss track mounting options Q What kind of training do therapists require to use ZeroG Passive ZeroG Passive is extremely easy to use With each system we include a DVD therapist training video that carefully explains how to use ZeroG Passive Each system also comes with a detailed user manual describing step by step instructions outlining the system s use Aretech s clinicians are also available to help answer any questions regarding training patients with ZeroG Passive Q How often does ZeroG Passive need to be serviced After the system is installed routine inspections of the system should be done This includes checking the straps on the harnesses the rope ratchets and other components We also recommend that the maintenance staff check the track installation hardware every 12 months to be sure nothing is loose or worn Q Is there a service contract available for ZeroG Passive No there is no service contract for ZeroG Passive We ask the fac
