Peripheral sensory feedback plays a crucial role in ensuring correct motor execution throughout hand grasp control. Previous studies utilized local anesthesia to deprive somatosensory feedback in the digits or hand, observations included sensorimotor deficits at both corticospinal and peripheral levels. However, the questions of how the disturbed and intact sensory input integrate and interact with each other to assist the motor program execution, and whether the motor coordination based on motor output variability between affected and non-affected elements (e.g., digits) becomes interfered by the local sensory deficiency, have not been answered. The current study aims to investigate the effect of …

The present study examined the potential of motor imagery training and investigated the role of motor imagery instructions (audio) to improve knee range of motion after a total knee replacement. The participants were randomly assigned to either an experimental motor imagery group (n=4) or a control group (n=6). Both groups performed specific exercises to improve their knee range of motion and strengthen their muscles. Participants in the Motor Imagery group performed a motor imagery training exercise for a knee flexion stretch on the stairs prior to performing the actual exercise. The motor imagery group demonstrated a significantly greater increase in …

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 …
Multi-Digit Coordination In Absence Of Cutaneous Sensory Feedback During Grasping Tasks, Christina Gioeli, Kerry Mcpartlan, Emily Reid, Matthew Turturro

Motor learning and adaptation to object properties and task requirements requires integration of cutaneous sensory feedback with motor commands. Joint mechanics constantly change, with individual joints or muscles compensation so performance output is the same per task. Effects of mixed cutaneous sensory feedback on multi-digit coordination is not well understood. Investigators sought to determine the influence absent cutaneous sensory feedback has on motor learning and adaptation, and how the CNS coordinates multi-digit mechanical output to adapt to manual tasks, with partially intact digital sensory feedback. 19 participants were randomly assigned for three-digit anesthesia administration (TIM- thumb, index, middle; TRL- thumb, …
Paired Associative Transspinal And Transcortical Stimulation Produces Bidirectional Plasticity Of Human Cortical And Spinal Motor Pathways, Luke Dixon, Mohamed Ibrahim, Danielle Santora

Anatomical, physiological, and functional connectivity exists between primary motor cortex (M1) and spinal cord neurons. Paired associative stimulation (PAS) produces enduring changes in M1 based on the Hebbian principle of associative plasticity. The present study aims to discover immediate neurophysiological changes on human corticomotor pathways by pairing noninvasive transspinal and transcortical stimulation via transcranial magnetic stimulation (TMS). We delivered paired transspinal and transcortical stimulation for 40-min at precise interstimulus intervals with TMS being delivered after (transspinal-transcortical PAS) or before (transcortical-transspinal PAS) transspinal stimulation. Transspinal-transcortical PAS markedly decreased intracortical inhibition, increased intracortical facilitation and M1 excitability with concomitant decreases of motor …

In the United States, osteoarthritis (OA) is the most common chronic illness in the adult population affecting an estimated 27 million individuals with a yearly health care cost of over $150 billion (CDC, 2014; Lawrence et al., 2008). The pathological osteoarthritic process results in the progressive degradation of articular cartilage due to chemical and biological imbalances within a joint (Weiland et al., 2005). These imbalances are not well understood and neither are the biomechanical joint changes that occur as a result. Due to these limitations, treating and monitoring this condition is a challenge to clinicians and the processes are currently …
