The effect and evaluation of stance control Knee Ankle Foot Orthosis on spatiotemporal parameters and kinematics in subjects with poliomyelitis
Journal Title: International Journal of Advanced Biotechnology and Research. - Year 2016, Vol 7, Issue 2
Abstract
ABSTRACT Background: Subjects with lower limb paralysis or weakness could be ideal candidates for knee-ankle-foot orthoses (KASOs). Stance Control KAFOs (SCKAFOs) has the ability of providing stability in stance and knee flexion in swing phase of gait. Purpose: The purpose of this study was design and evaluation of a SCKAFO on walking in subjects with poliomyelitis. Methods: Spatiotemporal parameters and kinematics of walking were measured in 7 poliomyelitis subjects. Three conditions were tested: walking with locked knee KAFO, walking with SCKAFO without (initial knee flexion mode) IF and walking with SCKAFO with IF. Results: Cadence and walking velocity were significantly increased when subjects used SCKAFO in comparison with locked KAFO. There was no significant difference in cadence and walking velocity between the SCKAFO without IF and SCKAFO with IF. Stance knee flexion was significantly increased when utilizing SCKAFO with IF compared to locked knee and SCKAFO without IF. Swing knee flexion was significantly increased when walking with SCKAFO in comparison with locked KAFO. Hip and pelvic ROM experienced a significant decrease walking with SCKAFO compared with locked KAFO. Hip flexion/extension ROM and pelvic tilt were significantly decreased using SCKAFO with IF compared to SCKAFO without IF. Conclusion: Patients used SCKAFO with IF had a more normal walking pattern compared to who utilized locked knee KAFO and SCKAFO without IF.
