Indications & Applications

The Sit-Up System provides carryover of clinical activities in the presence of the following indications and diagnoses:

  • Somatosensory processing deficits that interfere with postural alignment and stability in sitting
  • Sensory- or stability-seeking movements in sitting seen in some children with ASD or DCD and that reduce
    with manual facilitation
  • Flexible lumbar kyphosis that is either actively or manually correctable without force
  • A need for assistance in core strengthening by facilitating lumbar extension during therapeutic exercise activities

Sit-Up System Product Information Sheet


The Sit-Up System features two thigh cuffs and a strong, elastic TogRite™ muscle-assist strap that helps the weak iliopsoas muscle to extend the lumbar spine and to abduct and laterally rotate the hips, building a wider, more stable base of support with a more vertical pelvis.

The Sit-Up System provides carryover of rehabilitation activities which offer significant immediate benefits:

  • Mimics & maintains unforced manual facilitation of improved posture
  • Provides flexible & comfortable postural support at the pelvis & hips where it matters most
  • Reduces degrees of freedom to aid in gaining sitting balance by stabilizing the base of support
  • Increases body awareness of the lumbar spine, hips, and pelvis
  • Can be used at school, therapy, home, or office
  • Worn over clothes – no privacy issues
  • Snaps on or off quickly.
