Abstract: Clinical gait analysis is now the standard-of-care for diagnosis and treatment of walking disorders in children with cerebral palsy and other neuromuscular conditions. Gait analysis includes 3D motion capture of kinematics (joint motion) and kinetics (joint forces), as well as electromyography (EMG) for muscle activity during gait. New computer simulations are used to clarify the musculoskeletal components of gait abnormalities. The kinematic, kinetic, and EMG data are interpreted along with energy cost of walking and with postural balance measures to determine risk of falls and to avoid unpredictable surgical outcomes. The gait analysis is reviewed to determine an optimal treatment plan by a multidisciplinary team of clinicians that includes physical therapists, orthopaedic surgeons, physiologists, engineers, and orthotists. This lecture will introduce students to clinical gait analysis and to a new, developing assistive technology that utilizes functional electrical stimulation (FES) for artificial walking: FES-assisted gait for children with cerebral palsy.


Dr. Jessica Rose's research focuses on the neuromuscular and musculoskeletal mechanisms underlying gait abnormalities in children with cerebral palsy (CP) and other pediatric orthopaedic conditions. As director of the Motion & Gait Analysis Lab at Lucile Packard Children's Hospital, her research has focused on the energy cost of walking, muscle pathology, selective motor control, postural balance, and motor-unit firing in CP.
Stanford Community Academic Research Profile

Adam Sheppard is currently working on applications of artificial walking technologies with a national research network that investigates the use of functional electrical stimulation (FES) to aid in the rehabilitation of walking disorders in children with cerebral palsy. He develops electrical stimulation sequences for muscle activation, integrating data from microelectromechanical systems (MEMS) sensors to provide real-time motion feedback and control for FES-assisted gait.
