Proportional upper limb recovery after stroke is predicated upon corticospinal tract integrity
For most patients after stroke, upper limb impairment resolves by approximately 70% of the maximum amount possible i.e., the proportional recovery rule (PRR; Prabhakaran et al., Neurorehabil Neural Repair 2008 22: 64-71). This presentation will demonstrate how the PRR relies on corticospinal system integrity as determined with transcranial magnetic stimulation and diffusion-weighted MRI. Data were obtained from 48 patients previously enrolled in an upper limb rehabilitation interventional trial.

Cerebral blood flow augmentation by external counterpulsation enhances corticomotor excitability in subacute stroke patients: a randomized controlled trial
External counterpulsation (ECP) enhances cerebral blood flow in patients with subacute ischemic stroke but whether it changes corticomotor excitability, which is a powerful prognostic predictor for motor recovery, remains unknown.

Dual-mode Noninvasive Brain Stimulation over Prefrontal Cortices on Working Memory in Stroke Patients
This study investigated the effects of dual-mode noninvasive brain stimulation (NBS) using the transcranial direct current stimulation (tDCS) and high frequency repetitive transcranial magnetic stimulation (rTMS) over bilateral dorsolateral prefrontal cortices (DLPFC) on verbal working memory (VWM) function in chronic stroke patients.

Enhanced motor function and neurophysiological correlates with navigated low-frequency repetitive transcranial magnetic stimulation over the contralesional motor cortex in stroke
The net effect of altered interhemispheric interactions between homologous motor cortical areas after unilateral stroke, has been previously shown to contribute to residual hemiparesis. Using this framework, we hypothesized that navigated 1 Hz repetitive transcranial magnetic stimulation (rTMS) over the unaffected hemisphere would induce a stronger response in patients with residual motor deficit than in healthy subjects, because an imbalance in inter-hemipsheric excitability may underlie motor dysfunction.

A Comparison of Primed Low-Frequency Repetitive Transcranial Magnetic Stimulation Treatments In Chronic Stroke
Preceding low-frequency repetitive transcranial magnetic stimulation (rTMS) with a bout of high-frequency rTMS called priming potentiates the after-effects of the former in healthy adults. The utility of primed rTMS in stroke remains under-explored despite its theoretical benefits in enhancing cortical excitability and motor function.

Primary motor cortex excitability during recovery after stroke: implications for neuromodulation
Non-invasive brain stimulation techniques may be useful adjuvants to promote recovery after stroke. They are typically used to facilitate ipsilesional cortical excitability directly, or indirectly by suppressing contralesional cortical excitability and reducing interhemispheric inhibition from the contralesional to ipsilesional hemisphere. However, most of the evidence for this approach comes from studies of patients at the chronic stage of recovery.

Effects of Bilateral Repetitive Transcranial Magnetic Stimulation on Post-Stroke Dysphagia
• Applying high-frequency rTMS at both motor cortices over the cortical representation of the mylohyoid muscles is effective to improve dysphagia suffering from subacute phase of stroke.• Bilateral rTMS stimulations led to better and faster improvement of swallowing function than unilateral rTMS and sham stimulation.

Physiological and behavioral effects of β-tACS on brain self-regulation in chronic stroke
Unlike in healthy controls, sensorimotor β-desynchronization (β-ERD) is compromised in stroke patients, i.e., the more severe the patient's motor impairment, the less β-ERD. This, in turn, provides a target substrate for therapeutic brain self-regulation and neurofeedback.

Effects of tDCS on Stepping Reaction in Healthy Adults and Individuals with Chronic Stroke
Stepping is an important protective reaction to prevent falls and fall related injuries and this ability is usually impaired in elderly and individuals with stroke. This impaired stepping reaction is characterized by prolong reaction time and decrease neuromuscular control. Transcranial direct current stimulation (tDCS) has been applied in human to enhance cortical excitability and in turnpromote overall neuromuscular control. Therefore it could be applied alone or with exercise to enhance stepping ability.

Effects of transcranial direct current stimulation combined with treadmill training on functional mobility in stroke survivors
Introduction: Compromised gait is an important functional limitation among stroke survivors. Treadmill training is used to improve the gait pattern in this population. Transcranial direct current stimulation (tDCS) can easily be combined with motor training and is believed to potentiate gains achieved during the rehabilitation process.
