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 is reseaching the neuromuscular and musculoskeletal
mechanisms underlying gait abnormalities in children with cerebral palsy (CP)
and other pediatric orthopaedic conditions. As a Professor of Pediatric
Orthopaedics in the School of Medicine and Director of the Motion & Gait
Analysis Laboratory 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.

Katelyn Cahill-Rowley is a bioengineer investigating
methods of early motor impairment identification in children born preterm with
very low birth weights. Specifically, she is using temporal-spatial gait data
and MEMs sensors to characterize upper- and lower-extremity function,
respectively, in 18-month-old toddlers. She is correlating these functional
assessments with DTI brain data and the current gold-standard of motor
development, the Bayley Scales of Infant Development, to determine their
predictive potential. |
