Indications for Use
Statement of indications 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: - 6. Comfort -- As with any individual -- able-bodied -- changes in position are necessary to maintain a state of comfort. - 7. Positioning Individuals without adequate upper-body stability can be tilted to allow gravity to hold them in position. - 8. Pressure Relief or Reduction Individuals who wish to, from time to time, 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. 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.
Device Story
TRx-CG Power Tilt and Recline System is an add-on power positioning system for wheelchairs. It enables users to independently adjust their seating orientation via tilt and recline functions. The system uses powered actuators to shift the center of gravity and change body orientation, facilitating pressure relief and postural support. Operated by the wheelchair user via integrated controls, the device allows for repositioning without an attendant. It is intended for use in any environment where the power wheelchair is operated. The device does not claim therapeutic effectiveness; its primary benefit is providing safe, reliable, and independent powered repositioning.
Clinical Evidence
No clinical data provided; bench testing only.
Technological Characteristics
Powered tilt and recline system for wheelchairs. Utilizes electric actuators for mechanical repositioning. System is designed for integration onto existing power wheelchair frames. No specific materials or software algorithms described.
Indications for Use
Indicated for individuals who drive a power wheelchair and require or desire position changes without attendant assistance for comfort, postural stability, or pressure redistribution.
Regulatory Classification
Identification
A powered wheelchair is a battery-operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position.
