Hastings JD, Rogers Fanucchi E, Burns SP. Wheelchair configuration and postural alignment in persons with spinal cord injury. Arch Phys Med Rehabil 2003;84:528-34. Objective: To determine whether postural alignment and shoulder flexion range differ for persons with spinal cord injury (SCI) seated in wheelchairs with standard configurations versus wheelchairs with posterior seat inclination and a low backrest set perpendicular to the floor. Design: Prospective repeated-measures study. Setting: Outpatient SCI clinic. Participants: Fourteen subjects with C6-T10 motor-complete SCI. Interventions: Subjects sat in 3 manual wheelchairs: standard setup E[amp]J Premier (S1), standard setup Quickie Breezy (S2), and test configuration Quickie TNT (T) with posterior seat inclination and a low backrest set perpendicular to the floor. Main Outcome Measures: Shoulder and neck alignment and pelvic tilt were determined from sagittal plane digital photographs at rest and with maximal vertical reach. Results: At rest, T produced less shoulder protraction than either standard configuration (difference between the mean values, S1: 1.6cm, P[equals].048; S2: 1.2cm, P[equals].013). S1 and S2 showed a greater head-forward position than T (differences between the mean values, S1: 6.5[deg], P[equals].008; S2: 6.3[deg], P[equals].013). T allowed greater humeral flexion than S2 (difference between the mean values: 3.7[deg], P[equals].036) and greater vertical reach above the seat plane than either conventional configuration (differences between the mean values, S1: 4.7cm, P[equals].005; S2: 4.1cm, P[equals].002). The indirect pelvic tilt measurement showed a trend (P[equals].06) toward greater posterior pelvic tilt with S1 and S2. Conclusion: The alternate configuration produces more vertical postural alignment and greater reach ability versus the standard factory setup wheelchairs.
