| Motion & Gait Analysis Laboratory Research |
Motion & Gait Analysis Laboratory research focuses on the neuromuscular (nerve and muscle) mechanisms that cause gait deficits in cerebral palsy (CP) and other musculoskeletal conditions. The mechanisms we investigate include:
-
Muscle pathology – the study of muscle fiber changes in spastic (stiff) muscle
-
Selective motor control – involuntary muscle activation patterns
-
Postural balance –how much the body sways while standing still
-
Neuromuscular activation and motor-unit firing in cerebral palsy
Our research also looks at:
-
The relationship between neonatal brain development and gait deficits in children born prematurely. We use a magnetic resonance imaging (MRI) technique called diffusion-tensor imaging (DTI) to look at the neonatal brain.
-
Postural balance abnormalities and cerebellar abnormalities in adults
Research on Elite Performance
This research examines the range of human movement capabilities. We are trying to understand how highly trained professionals move in certain ways. We have studied professional golfers, dancers, musicians and tai chi masters. This work is also part of the Anatomy of Movement (Ortho 222) course taught at Stanford University.
Merce Cunningham Modern Dance
Our research showed these dancers:
-
Move the torso as if it were a limb
-
Make frequent and unexpected changes in direction
-
Have an extraordinary sense of balance
Tai Chi Master
We are currently investigating a Tai Chi master’s movements.
Violinist
Professional Golfer
We measured the hip and shoulder angles of ten Stanford alumni professional golfers as they swung a golf club. The rotation between the hip and shoulders during the golf swing is commonly referred to as the “x-factor”.
Our research showed:
-
Results were highly consistent among the golfers
-
The professional golfers’ peak x-factor occurs before their peak torque.
-
Peak torque correlated most highly to power generation
