  Mehta, Ricky (Georgia Institute of Technology, 2016-04-15)

  Major muscle groups (e.g. triceps surae, quadriceps, hamstrings, triceps brachii) contain synergist muscles that cross either one or two joints; they are called one- and two-joint muscles. The functional significance of ...

• Substrate-level control of glucose metabolism in C2C12 myotubes 

  Hsu, Chia (Georgia Institute of Technology, 2016-03-30)

  Metabolic flexibility is critical for muscle to maintain proper function and overall health. Muscle adapts to metabolic stress with increasing ATP synthesis by enhancing the rate of glycolysis and mitochondrial respiration. ...

• The influence of wheelchair mechanical parameters and human physical fitness on propulsion effort 

  Lin, Jui-Te (Georgia Institute of Technology, 2016-11-15)

  The majority of wheelchair studies that attempt to evaluate propulsion efforts across wheelchair configurations examines long and steady propulsion. However, the results of these studies cannot represent performance during ...

• Spatiotemporal patterns of parietofrontal activity and eye movements underlying the visual perception of complex human tool use 

  Natraj, Nikhilesh (Georgia Institute of Technology, 2015-11-16)

  When watching a child learning to use a spoon, a mother is immediately able to recognize the error when the child grabs the bowl rather than the stem, or when the child uses the spoon to try and scoop paper. Recognizing ...

• Neuromechanics of locomotion: Insights from the walk-to-run transition in amputees and pedaling in able-bodied individuals 

  Norman, Tracy L. (Georgia Institute of Technology, 2015-10-16)

  Afferent feedback is important for modulating locomotion and maintaining stability. Studying locomotor extremes and applying perturbations to normal locomotion allows us to probe the effects of afferent feedback on the ...

• Influencing motor behavior through constraint of lower limb movement 

  Hovorka, Christopher Francis (Georgia Institute of Technology, 2015-04-29)

  Limited knowledge of the neuromechanical response to use of an ankle foot orthosis-footwear combination (AFO-FC) has created a lack of consensus in understanding orthotic motion control as a therapeutic treatment. Lack of ...

• Adaptation of locomotor control in able and impaired human walking 

  Toney, Megan (Georgia Institute of Technology, 2014-06-13)

  Extensive research has documented the stereotypical kinematic and kinetic patterns in healthy human walking, but we have a limited understanding of the neuromechanical control principles that contribute to their execution. ...

• Altered intermuscular force feedback after spinal cord injury in cat 

  Niazi, Irrum Fawad (Georgia Institute of Technology, 2015-07-24)

  Bipeds and quadrupeds are inherently unstable and their bodies sway during quiet stance and require complex patterns of muscle activation to produce direction-specific forces to control the body’s center of mass. The ...

• Understanding the neurophysiology of action interpretation in right and left-handed individuals 

  Kelly, Rachel Louise (Georgia Institute of Technology, 2015-04-08)

  Investigating the neurophysiology behind our action encoding system offers a way of probing the underlying mechanisms regarding how we understand seen action. The ability to mentally simulate action (motor simulation) is ...

• Fatigue mechanisms in sedentary and endurance trained adults: effects of nutritional countermeasures 

  O'Dea, Namrita Kumar (Georgia Institute of Technology, 2015-04-08)

  Physical inactivity is a major risk factor for chronic disease; yet the majority of the population does not meet physical activity recommendations, with fatigue being a primary underlying reason. Common nutritional supplements ...

• Promoting enhanced motor planning in prosthesis users via matched limb imitation 

  Cusack, William Fitzpatrick (Georgia Institute of Technology, 2014-03-13)

  As of 2005, there were over 1.5 million amputees living in the United States, more than 548,000 of them with upper extremity involvement. The total number of amputees is projected to rise to at least 2.2 million by 2020. ...

• Task dependent effects of baroreceptor unloading on motor cortical and corticospinal pathways 

  Buharin, Vasiliy E. (Georgia Institute of Technology, 2013-08-27)

  Corticospinal and intracortical excitability are excitability measures of the central nervous system responsible for motor generation, and are studied for their contribution to fine motor skill execution and learning. ...

• Injury compensation reveals implicit goals that guide locomotor coordination 

  Bauman, Jay Morris (Georgia Institute of Technology, 2012-04-08)

  Locomotion persists despite changes in external and internal circumstances. Motor responses to gait impairment exhibit commonalities across various taxa and types of injury, yet we lack a systematic understanding of ...
