OBJECTIVES/HYPOTHESIS The objective was to determine whether low-frequency repetitive transcranial magnetic stimulation (rTMS) improves tinnitus by decreasing neural activity in auditory processing regions of the temporal cortex and the utility of positron emission tomography (PET) for targeting treatment. STUDY DESIGN Randomized, sham-controlled(More)
OBJECTIVES/HYPOTHESIS Low-frequency repetitive transcranial magnetic stimulation (rTMS) has been shown to alleviate tinnitus perception, presumably by inhibiting cortical activity associated with tinnitus. We conducted a pilot study to assess effectiveness of neuronavigated rTMS and its effects on attentional deficits and cortical asymmetry in four patients(More)
BACKGROUND Intensive motor training is a therapeutic intervention that supports recovery of movement function after stroke by capitalizing on the brain's capacity for neuroplastic change. Peripheral nerve stimulation and transcranial direct current stimulation are neuromodulation techniques that can upregulate neuroplasticity and, in turn, enhance outcomes(More)
OBJECTIVES/HYPOTHESIS Correlate subjective improvements in tinnitus severity with restoration of cortical symmetry and sustained attention after neuronavigated low-frequency, repetitive transcranial magnetic stimulation (rTMS). STUDY DESIGN Case study. METHODS Positron emission tomography and computed tomography imaging (PET-CT) guided rTMS was(More)
OBJECTIVES/HYPOTHESIS A single patient was tested to examine the safety and feasibility of using maintenance sessions of low-frequency repetitive transcranial magnetic stimulation (1 Hz rTMS) to reduce tinnitus loudness and prevent its return over time. STUDY DESIGN Interrupted time series with multiple replications. METHODS Tinnitus loudness was(More)
A valid sham control is important for determining the efficacy and effectiveness of repetitive transcranial magnetic stimulation (rTMS) as an experimental and clinical tool. Given the manner in which rTMS is applied, separately or in combination with self-regulatory approaches, and its intended impact on brain states, a valid sham control of this type may(More)
The relationship between arousal, perception, and visual neglect was examined in this case study. Cold pressor stimulation (CPS: immersing the foot in iced water) was used to manipulate arousal and to determine its effects on contralesional neglect, perception of stimulus intensity (magnitude estimation), reaction time, and an electrophysiological correlate(More)
The present study examined how cold pressor stimulation influences electrophysiological correlates of arousal. We measured the P50 auditory evoked response potential in two groups of subjects who immersed their foot in either cold (0-2°C) or room temperature (22-24°C) water for 50 seconds. The P50, which was recorded before and after stimulation, is(More)
OBJECTIVES 1) To investigate the feasibility of combining transcranial direct current stimulation (tDCS) to the lower extremity (LE) motor cortex with novel locomotor training to facilitate gait in subjects with chronic stroke and low ambulatory status, and 2) to obtain insight from study subjects and their caregivers to inform future trial design.

BACKGROUND Stroke continues to be a major public health concern in the United States. Motor recovery in the post-acute stages of stroke is possible due to neuroplasticity, or the capacity of the brain to reorganize. OBJECTIVE This case study tracks neuroplastic and motor change in a subject with severe hemiparesis following an extensive middle cerebral(More)
