Quantifying Control

A child walking in the motion analysis lab at Gillette Children's Specialty Healthcare.


In collaboration with Gillette Children’s Specialty Healthcare and NINDS we are quantifying patient-specific changes in neuromuscular control by intergrating clinical gait analysis and utilizing both synergy analysis and dynamic musculoskeletal simulation computations. The goals of this project are to evaluate if muscle synergies during gait in individuals with cerebral palsy change before and after multi-level orthopedic surgery and if synergies predict treatment outcomes for improved walking ability.

Impaired neuromuscular control impacts coordination, limits mobility, and hinders quality of life for individualswith cerebral palsy, stroke, and other neurologic disorders. However, identifying and treating impaired neuromuscular control is challenging due to the complexity of the neuromuscular system. Electromyography (EMG) can monitor muscle activity during tasks such as walking and is commonly used as a measure of altered neuromuscular control. Changes in EMG may be due to a variety of factors including altered descending drive, spasticity, or kinematics. Understanding the source of an individual’s inappropriate muscle activity is critical for identifying the cause of pathologic movement and designing optimal treatment strategies. We are using a combination of clinical gait analysis, muscle synergy analysis, and musculoskeletal simulation to quantify inappropriate muscle activity and use this information to improve treatment planning.
