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.

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. |
