Pelvic Floor Strong Reviews
Editor, Father, and Volunteer in USA
An important practicality of people in wheelchairs is that they must be in a balanced position throughout the ride - no slouching or drooping, no leaning forward or backward, no tipping, no sacral sitting and/or no slumping. We are after a neutral tilt, no sitting outside the "box", without a posterior pelvic tilt or with the pelvis not in the sacral sitting position but with anterior support. (Sacrum, Latin, "A triangular bone consisting of five fused vertebrae forming the posterior sect-ion of the pelvis"; Greek, "sacred bone once used in sacrifices".)
The reason for the insistence on this required posture is the fact that people in wheelchairs have a high risk of bedsores due to the lack of movement in the legs, poor circulation of the blood due to the lack of movement and inactivity due to possible recovery from a stroke and/or surgery.
