Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova
Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova
Dissertations, Theses, and Capstone Projects
Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after …
The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer
The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer
Dissertations, Theses, and Capstone Projects
Primate evolutionary history is inexorably linked to the evolution of a broad array of locomotor adaptations that have facilitated the clade’s invasion of new niches. Researchers studying the evolution of primates and of their individual locomotor adaptations have traditionally relied on bony morphology – a practical choice given the virtual non-existence of any other type of tissue in the fossil record. However, this focus downplays the potential importance of the many other structures involved in locomotion, such as muscle, cartilage, and neural tissue, which may each be influenced by separate selective forces because of their different roles in facilitating movement. …
Reliability Of Clinical Evaluators Of Spasticity In Patients With Stroke, Tiffany Alvino, Shiney David, Chelsea Gendvil
Reliability Of Clinical Evaluators Of Spasticity In Patients With Stroke, Tiffany Alvino, Shiney David, Chelsea Gendvil
Dissertations, Theses, and Capstone Projects
Spasticity is characterized by hyperexcitable stretch reflexes with amplitude increases in response to velocity dependent passive movement and resistance. Spasticity is the result of abnormal function of segmental and suprasegmental neuronal circuits. The objective of this study was to determine any positive correlation between three clinical evaluators of spasticity (i.e., the pendulum test, the patellar tendon tap test (PTT), and the Modified Ashworth scale) in their reliability to assess spasticity in people post-stroke. It was hypothesized that the use of force movement sensors along with surface electromyography increases the reliability of the standardized clinical tests. The results show that all …
