Wheelchair Seating: Considerations For The Hands Dependent Sitter

---

1.  Which of the following are goals of positioning the hands-dependent sitter? Provide adequate proximal support for distal control Promote function Mitigate pressure issues All of the above

2.  What is a hands-dependent sitter? Independent sitter Requires hands on surface to maintain sitting Requires external supports to maintain sitting Cannot be seated

3.  What seating feature is typically required to prevent collapse into posterior pelvic tilt? Cushion with significant posterior pelvic support and strong contact with the back at the level of the pelvis No contact with the back at the level of the pelvis The proper pelvic belt angle A linear cushion

4.  What is the purpose of a back that supports both the angle of the pelvis to lower back as well as the angle of the thigh to trunk? To create a lumbar curve To provide growth To provide adjustability To prevent pressure issues

5.  Why is a lateral trunk support important for a hands-dependent sitter? To optimize hands-free functioning To maintain lateral spinal symmetry To provide support during functional tasks All of the above

6.  Paul has tight hamstrings. If his knees are extended beyond 90 degrees, what destructive posture is likely to occur? Pelvic obliquity Pelvic rotation Posterior pelvic tilt Anterior pelvic tilt

7.  Paul tends to dynamically extend within his current seating system, negatively impacting his function. With significant pelvic and low back support, his dynamic extension is reduced. What is a possible reason? Poor postural support increases the effort required to stay upright Maintaining the identified posture and increased hip flexion reduces movement into excessive extension He has increased muscle tone He demonstrated low muscle tone

8.  Paul demonstrates increased trunk and head control in his new seating system. Why could this be the case? He has been told to keep his head up He is in a posterior pelvic tilt Increased stability has improved sitting balance The angle of the pelvic belt

9.  What is an advantage of a molded seating system for Paul? Cost Minimizing risk of spinal curvature Growth Temperature regulation

10.  Why is the hands-dependent sitter at more pressure risk than the hands-free sitter? Decreased sensation Lack of caregiver support Less ability to independently shift weight Muscle atrophy
