Alteration in neck neuromuscular responses and upper limb proprioception in response to neck muscle fatigue
Zabihhosseinian, Mahboobeh (2014-07-01)Neck and upper limb disorders constitute two of the most frequent musculoskeletal problems that place a huge burden on the healthcare system. Neck muscles have a very high density of muscle sensory input to the central ... -
Alterations in neck muscle performance and proprioception with fatique, altered posture and recurrent neck pain
Barker, Ian (2011-07-01)Altered neuromuscular processing and motor output as both a risk and perpetuating factor for chronic neck pain is a relative new area of study. The cervical flexion relaxation response (FRR) is a reproducible and reliable ... -
Assessing neurophysiological and behavioural outcomes of the proximal upper limb muscles in response to novel motor skill acquisition
O'Brien, Sinead (2017-08-01)A single session of motor training with the distal upper limb muscles leads to changes in brain and spinal cord processing. However, the neuroplastic response of the proximal upper limb muscles to novel motor training has ... -
Audiovisual multisensory integration in young adults with and without a diagnosis of Attention-Deficit/Hyperactivity Disorder
McCracken, Heather (2018-08-01)Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with behavioural and neurophysiological characteristics. Several cortical structures that are altered in ADHD are involved in the process of ... -
Baseline comparability to accelerometry data and changes in standing balance over the course of an athletic season using a postural sway assessment tool
Riley, Patricia A. (2016-01-01)Changes in balance ability can be a sensitive measure of post-concussion changes in brain function. However there is a need to determine the most reliable, valid and practical ways to assess balance abilities (i.e. degree ... -
Behavioural and neurophysiological measures of haptic feedback during a drilling simulation
Grant, Brianna L. (2019-08-01)Virtual environments (VEs) and computer-generated simulations are becoming more prevalent as tools for education, rehabilitation, and training purposes. As technology enhances the quality and quantity of human-machine ... -
Changes in corticomotor plasticity induced by cardiovascular exercise and strength training in sedentary young adults
Behbahani, Hushyar (2014-08-01)Recent studies have further elucidated the properties of cardiovascular and strength training-induced changes in motor cortex (M1) plasticity (i.e. the strengthening and reorganization of neural connections). However, the ... -
Cortical and cerebellar motor processing changes subsequent to motor training and cervical spine manipulation
Daligadu, Julian (2012-07-01)Chronic neck pain, including subclinical neck pain (SCNP), is a significant problem that places a burden on the healthcare system. Chiropractic manipulation has shown not only to be effective in treating symptoms of neck ... -
Development of instruments to access physiological and physical neck pain risk factors
Gray, Diana (2011-07-01)Neck pain has the potential to result in altered afferent input to the central nervous system which may thereby result in altered sensorimotor integration and eventually further disability. One “at risk” population for ... -
The effect of atlanto-occipital manipulation on neck and shoulder proprioception and range of motion: a randomized controlled trial
Hossinzehi, Halima (2021-12-01)Long-term neck pain is associated to maladaptive neuroplastic alterations in the brain, that affect head and neck proprioception. The One to Zero (OTZ) tension technique aims to correct dysfunction between the occiput (C0) ... -
The effect of experimental pain on motor training performance and sensorimotor integration
Dancey, Erin Margaret (2012-07-01)Sensorimotor integration (SMI) is the ability of the central nervous system (CNS) to integrate afferent (incoming) information from different body parts and formulate appropriate motor output to muscles. Effective sensorimotor ... -
The effect of neck muscle fatigue on shoulder humeral rotation proprioception
Russell, Matthew S. (2019-11-01)Fatigue of the cervical extensor muscles (CEM) is thought to disrupt afferent feedback from postural mechanoreceptors as it has been observed to cause decrements in upper limb proprioceptive accuracy. There has been limited ... -
Effect of neck muscle vibration on upper limb sensorimotor integration and motor performance
Tabbert, Hailey (2022-07-01)Upper limb control depends on accurate internal models of the position of the limbs relative to the head and neck. The cerebellum is heavily involved in SMI of neck sensory inputs and motor learning; therefore, it is likely ... -
Effects of altered sensory input from the neck on cerebellar function, body schema and sensorimotor integration
Baarbé, Julianne (2015-06-01)Neck muscles have a high density of muscle spindle afferents and their input is critical for formulating the perception of head position relative to the body. Chronic alterations in afferent input from the neck may be ... -
The effects of forward head posture on sensorimotor integration and neck and shoulder proprioception
Patrick, Tracey A. (2019-12-01)Forward head posture (FHP) is commonly seen in today’s society as a result of excess technology use. The central nervous system uses the position of the head with respect to the neck when interpreting the location of the ... -
The effects of motor task complexity on sensorimotor integration: implications for healthy and subclinical populations
Andrew, Danielle (2014-07-01)The central nervous system’s (CNS) plastic ability allows for adaptation to the various physiological changes and experiences we encounter. This occurs through dynamic shifts within the connections and strengths of neural ... -
Examining the relationship between cervical anthropometics, head kinematics and cervical muscle responses to sudden head perturbations in competitive ice hockey players
Debison-Larabie, Chadwick (2016-04-01)Sex differences in neck muscle characteristics may explain the higher incidence of concussions in female hockey players. The purpose of this study was to examine differences in cervical muscle characteristics between male ... -
Exploring lateralized sensorimotor processing using somatosensory evoked potentials
Gilley, Ryan (2017-08-01)Differences exist between the two upper limbs in the chosen motor control strategy when moving in dynamic environments. To date, a large body of literature has explored these differences but few studies have incorporated ... -
Factors affecting the impact of general elective courses which include physical activity on post-secondary student mental health
MacIntosh, Lindsey (2017-05-01)Post-secondary students are vulnerable to depression, anxiety and stress when faced with academic pressures. Physical activity can be beneficial in alleviating mental health symptoms, therefore, physical activity was built ... -
