Filter by:Motor imagery is defined as a dynamic mental process of an action, without its real motor execution. Action observation evokes an internal, real-time motor simulation of the movements that the observer is perceiving visually. Both MI and AO have been shown to produce a neurophysiological activation of the brain areas related to the planning and execution of voluntary movement in a similar manner how the real action.
Influence of virtual reality games(Wii Fit) on knee proprioception after anterior cruciate ligament reconstruction (ACLR) will be measured in 30 postoperative patients. The age of participants will be ranged from 20 to 30 years old. Subjects will be randomly assigned to Group A is the study group and Group B is the control group.
Influence of mental practice and proprioceptive neuromuscular facilitation on muscle strength of upper limb and hand grip will be measured in 30 to 50 healthy students with right dominant hand, Their age will be ranged from 18 to 26 years old. Subjects will randomly assigned to either proprioceptive neuromuscular facilitation (PNF) group or proprioceptive neuromuscular facilitation with mental practice (PNFMP) group.
This study will be conducted to investigate the effect of BMI on hand grip force in healthy subjects. The participants in this study will be 90 healthy subjects with right dominant lower limb (49 females and 49 males) they will be recruited from College of Applied Medical Sciences, Jazan University.
This study examines the effectiveness and appropriateness of a written physical activity policy implemented in licensed centre-based childcare on the physical activity levels of toddlers (1-2) and preschoolers (3-5 years). Half of the childcare centres will adopt the physical activity policy while the other half will continue with their typical daily programming and care. It is hypothesized that children enrolled in childcare centres that adopt the policy will display increased levels of physical activity during, and after participating in the policy intervention compared to children enrolled in centres that do not adopt the policy.
Motor control, notably expressed through the complexity of the variability of the locomotor pattern, is disturbed at the central level by an apprehension of pain and movement, more than pain itself (or by biomechanical / structural damage of the spine) in chronic low back pain (cLBP) patients. The aim of this study is to control that variability is reduced during gait at comfortable level and to test that distraction can reduce pain avoidance and therefore increase variability in cLBP patients.
Less than 50% of stroke survivors progress to independent community ambulation. Even among the stroke survivors who achieve independent ambulation, significant residual deficits persist in balance and gait speed, with 60% of persons post-stroke reporting limitations in mobility related to walking.Consequently maximizing recovery of locomotor function is the focus of neurorehabilitation efforts worldwide. A recently completed clinical trial from members of this investigative team demonstrated that 6 weeks of treadmill training elicits substantial improvements in over ground walking speed and symmetry in persons following stroke. Consistent with the goals of the South Carolina Stroke Rehabilitation Research Center (SCSRRC) and NIH Brain Initiative, the investigators now plan to investigate the effects treadmill-assisted gait training have on cortical control of bipedal movement in chronic stroke patients. Although previous investigators have assessed neural activity during simulated walking using motor imagery, motor imagery does not simulate the typical sensory feedback associated with active movement. To move the field forward, it is necessary to measure active bipedal movement in the MR-environment in healthy volunteers, before moving forward in stroke patients.
In a recent publication by Gamboa et al. 20108 it was shown that extended theta-burst stimulation duration might have reverse effects on cortical excitability when compared to the original Huang et al. 2005 publication. While the post treatment effects of the original Huang et al. 2005 protocol were successfully replicated, when continuous theta burst stimulation (cTBS) protocols were doubled to 1200 pulses over 80 seconds and the iTBS protocols were doubled to 1200 pulses over 390 seconds, there was increased facilitation after the prolonged cTBS and decreased excitability after prolonged iTBS. Currently there is an interest in optimizing repetitive transcranial magnetic stimulation (rTMS) protocols and in particular theta burst stimulation as both a therapeutic and an investigational tool. In Hanlon et al. 2015, a novel theta burst paradigm is described in which two trains of 1800 pulses of cTBS were administered, each train separated by a one-minute interval. In this study 11-cocaine dependent individuals underwent cTBS over the medial prefrontal cortex (MPFC) and showed attenuated craving as well as decreases in activity of the striatum and anterior insula. This study aims to replicate the findings of the Gamboa and Huang protocols as well as investigate how novel theta burst stimulation paradigms such as those described in Hanlon et al. 2015, which are currently being explored as therapeutic methods in addiction may change cortical excitability.
The main aim of this study is to describe differences in development of health and motor performance over time in relation to type of school and other background variables.
