• Kinematic Improvement Differs Between Transradial Versus Partial-Hand Prosthesis Use Following Interlimb Training 

  Keeton, Emily

  About 33% of upper extremity amputees reject their prosthetic device due to perceived lack of functionality in daily life (Cusack et al., 2014). A way to bypass the lack of device use during the healing period is to begin ...

• Implicit awareness during skilled motor learning and the implications for rehabilitation 

  Turner, Emma M.

  Motor skills and sequential motor learning are essential in our day to day lives, however, little behind the brain regions involved is known. This means that when someone has a deficiency in their motor skills or their ...

• Limb position sense: Role of limb posture, visual experience, and input from muscle spindle Ia afferents 

  Oh, Kyunggeune (Georgia Institute of Technology, 2019-04-02)

• Neurobehavioral Patterns during Action Observation and Execution of Complex Goal-Directed Movements 

  Atawala, Neel

  The production and mastery of complex action begins with action understanding, a process which arises from the observation of others. The mechanisms through which humans engage in action understanding are still debated, ...

• Joint Stiffness Fluctuations are Potentially Associated with Postural Sway 

  Gidwani, Simran

  Joint stiffness can be induced by simultaneous contraction of muscles on opposite sides of the joint. When the electrical oscillations of these antagonistic muscles are in-phase, fluctuations in joint stiffness can occur, ...

• Autogenic and intermuscular pathways in cats with partial spinal cord lesions 

  Kajtaz, Elma (Georgia Institute of Technology, 2019-01-15)

  Bipeds, like humans, stand with two-thirds of their body mass at about two-thirds of their body height above the ground, which, distributed within a relatively narrow base of support, makes us an inherently unstable system. ...

• Does dehydration affect brain structure, function, and cognitive-motor performance? 

  Wittbrodt, Matt T. (Georgia Institute of Technology, 2018-04-06)

  There is reason to believe body water deficits (dehydration) adversely impact the central nervous system despite protective physiological mechanisms to maintain brain homeostasis. Early animal models suggested severe ...

• Quadrupedal locomotion with a unilateral bone-anchored transtibial prosthesis in the cat 

  Jarrell, Joshua Ryan (Georgia Institute of Technology, 2017-11-10)

  Bone-anchored limb prostheses offer numerous advantages over conventional socket-supported prostheses. As opposed to socket prostheses, loads on a bone-anchored prosthetic limb during natural activities are directly ...

• Neurobehavioral quantification of the transition to explicit awareness in skilled motor learning: Implications for rehabilitation 

  Lawson, Regan (Georgia Institute of Technology, 2017-11-08)

  We often take for granted the ability to learn and execute sequential movements in a smooth, automatic manner on a continual daily basis. Unfortunately, many patient populations exhibit deficits in motor learning, impairing ...

• Neuromechanical activity of the wrist muscles during stabilization tasks 

  Brown, Ellenor J. (Georgia Institute of Technology, 2017-08-28)

  Wrist joint stability is vital to hand function and thus overall upper limb function. The overarching goal of the study is to understand the neuromuscular control and mechanical properties of the wrist muscles for wrist ...

• Changes in leg and joint coordination during locomotor adaptation in amputees and able-bodied controls 

  Selgrade, Brian Paul (Georgia Institute of Technology, 2016-06-06)

  Activities of daily life require humans to locomote in unfamiliar environments. We respond to these new environments through adaptation, a gradual change in movement parameters in response to a sensory error caused by ...

• Mechanisms of coordination between one- and two-joint synergist muscles 

  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 ...
