Abstract
Studying the Effects of Using Two Types of Afos on the Ankle and Knee Joints Kinematics and Kinetics During Walking in the Sagittal Plane for A Patient with Severe DDH; Part 2
Highlights
Many patients with developmental dysplasia of the hip joint disorders experience some limitations with gait, such as drop foot during the swing phase, mediolateral instability of the ankle joint in the stance phase, and insufficient plantar flexor activity
During walking in the sagittal plane, the maximum dorsiflexion angle for all conditions happened between the terminal stance phase and the pre-swing phase, not significantly both orthoses have increased the dorsiflexion angle by mean difference (2.71, 4.2 degrees) respectively
The planter flexion angle reached the maximum during the time between the toes-off the ground phase and the initial swing phase, it is worth noting that there is a significant change as both orthosis conditions have increased the plantar-flexion angle by mean difference (21.1, 14) respectively
Summary
Many patients with developmental dysplasia of the hip joint disorders experience some limitations with gait, such as drop foot during the swing phase, mediolateral instability of the ankle joint in the stance phase, and insufficient plantar flexor activity. Literature findings suggest that ankle-foot orthosis (AFOs) can manage various lower limb disorders and neuromuscular These assisted devices had positive impacts on kinematics, balance, and spatiotemporal gait parameters [2]-[6]. There are many features generated by the AFO Leaf Spring Orthosis such as the Injection-moulded polypropylene is lightweight, Variable thickness throughout the orthosis provides strength, provides good toe clearance and support, and Excellent fit for most types of shoes
