## Indications for use
The TRx-CG is appropriate for use by any individual who drives a.power wheelchair and who desires or requires a change of position without having to utilize the services of an attendant. Needs for position changes include: +:+ All positioning benefits associated with the tilflrecline product - P Comfort - As with any individual - able-bodied or disabled - changes in position are necessary to maintain a state of comfort. > Repositioning - Individuals without adequate upper-body stability can be tilted to allow gravity to hold them in position. > Pressure relief - Individuals who wish, from time to time, to redistribute pressures from one area of the body to another, can do so by tilting and/or reclining. By changing the individual’s orientation in space, pressures caused by gravity will shift. +:+ PositioningNersatility - Individuals are able to reach higher elevations in a seated position, increasing their range of motion and accessibility. Motion-Concepts makes no claims as to the therapeutic effectiveness of the products. Our only claims relate to the ability of the products to provide safe and reliable powered repositioning on the equipment onto which they are installed. TRx-CG Power Positioning Systems are to be installed ONLY by qualified Dealers. The above indications for use are identical to those of the Permobil Tilt/Recline/Elevating Se.aS Systemto which we -areclaiming -substantial equivalence.
