PURPOSE (1) To compare the kinematic motion of the hyoid bone and the epiglottis in healthy controls and a sample of patients with dysphagia of different etiologies, and (2) to evaluate the potential value of kinematic swallowing analysis to differentiate the mechanism of dysphagia. METHODS We performed two-dimensional video motion analysis of the hyoid(More)
OBJECTIVE To test the hypothesis that 10 sessions of transcranial direct current stimulation combined with occupational therapy elicit more improvement in motor function of the paretic upper limb than sham stimulation in patients with subacute stroke. DESIGN Eighteen patients with subacute stroke with hand motor impairment were randomly assigned to one of(More)
PURPOSE Previous reports have suggested that noninvasive cortical stimulation could influence speech production in patients with chronic stroke. Here, we evaluated the hypothesis that cathodal transcranial DC stimulation (ctDCS), a technique that decreases excitability of stimulated cortical sites, applied over a healthy right Broca's homologue area could(More)
OBJECTIVE To evaluate the effect of an aquatic therapy programme designed to increase balance in stroke survivors. DESIGN A randomized, controlled pilot trial. SETTING Rehabilitation department of a university hospital. SUBJECTS Ambulatory chronic stroke patients (n = 25):13 in an aquatic therapy group and 12 in a conventional therapy group. (More)
BACKGROUND AND PURPOSE Recent work demonstrated that application of peripheral nerve and cortical stimulation independently can induce modest improvements in motor performance in patients with stroke. The purpose of this study was to test the hypothesis that combining peripheral nerve stimulation (PNS) to the paretic hand with anodal direct current(More)
PURPOSE Attention decline after stroke is common and hampers the rehabilitation process, and non-invasive transcranial direct current stimulation (tDCS) has the potential to elicit behavioral changes by modulating cortical excitability. The authors tested the hypothesis that a single session of non-invasive cortical stimulation with excitatory anodal tDCS(More)
To determine whether multiple sessions of electrical stimulation (ES) applied to neck muscles improve swallowing function and whether this improvement is accompanied by cortical reorganization in patients with dysphagia, before-after trials were performed on eight subjects. ES was applied for 1 hour, 5 days a week for 2 weeks. Swallowing function(More)
This study was undertaken to test the hypothesis that a combination of excitatory anodal transcranial direct current stimulation (tDCS) to the contralateral motor cortex and inhibitory cathodal tDCS to the ipsilateral motor cortex of the motor performing hand (Bi-tDCS) would elicit more implicit motor sequence learning than anodal tDCS applied to the(More)
OBJECTIVE To test whether multiple sessions of inhibitory low-frequency repetitive transcranial magnetic stimulation (rTMS) applied to the left parietal area can improve hemispatial neglect after stroke. DESIGN An open-label design. PATIENTS Seven consecutive patients with hemispatial neglect after right hemispheric stroke were compared with 7(More)
BACKGROUND AND PURPOSE Shoulder pain is frequent after stroke and interferes with the rehabilitative process and outcome. However, treatments used for hemiplegic shoulder pain are limited and largely ineffective. This prospective, randomized, double-blind controlled study was conducted to compare the efficacies of botulinum toxin type A (BoNT-A) and(More)
