Neuromechanical Links between the Brain and Muscle Coordination during Balance Performance following an Anterior Cruciate Ligament Injury
Poor postural control in ACLR patients has been suggested as evidence of neuromuscular control deficits, which may indicate maladaptation of the brain’s function following a ACL rupture, but limited data exist. The purpose of this project is to explore how the ACL injury affects neural processing in several regions of the brain associated with maintenance of dynamic joint stability during postural control tasks in ACLR patients when compared to healthy controls.
Brain Function in Older Adults during Physical Function Tests
Physical functional decline, which is common in older adults, has a significant impact on the quality of life and may be associated with inefficient neural processing in the brain. The purpose of this project is to examine the magnitude of interaction between cerebral cortical activation in various regions of the brain and physical function assessments in older adults and to determine whether neural activation patterns can predict risk of functional decline in old adults compared to young healthy controls.
tDCS Neuromechanical Influence on Knee Proprioception
Proprioceptive deficit is one of the problems after an anterior cruciate ligament (ACL) reconstruction, leading to persistent pathological complications, and is highly associated with neural adaptation in the central nervous system (CNS). Transcranial direct current stimulation (tDCS) application that directly stimulates the brain’s regions has shown improvement in muscle activation and postural control, but limited data exist its therapeutic effects on knee proprioception. The purpose of this project is to explore the therapeutic effects of tDCS on neural processing in the brain associated with knee muscles strength, proprioception, and functional outcomes in ACLR patients when compared to the healthy individuals.
The NSIR includes E-prime, Chronos response box, and 32-channel wireless electroencephalograph (EEG) system. The NSIR-Lab has also access to a variety of other equipment belonged to the department, including a Dual X-ray Absorptiometry (DXA) unit, a digital ultrasound, 12 motion capture cameras (we may have new system), Bertec force plate, Biodex SD balance system and dynamometer Pro 4, Delays Trigno Avanti 16-channel wireless electromyograph (EMG) system, and Neuroconn tDCS.
