A Pelvic Wheelchair Robot for Active Postural Support (pWRAPS)

This technology is a robotic device to accommodate seated pelvic movements while supporting the trunk and upright posture in individuals with severe impairments in trunk control.

Unmet Need: An active device to support upright posture during sitting in a wheelchair

Individuals with severe impairments in trunk control have difficulty maintaining and controlling upright posture when seated. Current options as straps and orthoses offer a passive support of the trunk and limit the user’s mobility. There is a need for a device which enhances motion control while facilitating daily activities.

The Technology: A Pelvic Wheelchair Robot for Active Postural Support (pWRAPS)

This technology is a robotic device, Pelvic Wheelchair Robot for Active Postural Support (pWRAPS), that accommodates seated pelvic movements while supporting the trunk and upright posture. With its adjustable pelvic brace and sensors connected to a control computer with virtual reality, this device can predict the kinematics of its user in real-time, allowing for a wider range of motion. This technology facilitates its user’s daily activities by supporting static and dynamic sitting, enhancing motion control accuracy, and providing active support of the pelvis.

Applications:

  • Wheelchair assistive device
  • Physical medicine and rehabilitation tool
  • Musculoskeletal disorder assistive device
  • Postural correction device

Advantages:

  • Wider dynamic range of motion
  • Real-time adjustment of position
  • Support static and dynamic sitting
