BACKGROUND The purpose of this study was to investigate the long-term efficacy of transcranial direct current stimulation (tDCS) in the neurorehabilitation of Alzheimer's disease (AD). METHODS Thirty-four AD patients were randomly assigned to three groups: anodal, cathodal, and sham tDCS. Stimulation was applied over the left dorsolateral prefrontal(More)
BACKGROUND Recent neuroimaging studies on poststroke aphasia revealed maladaptive cortical changes in both hemispheres, yet their functional contribution in language recovery remains elusive. The aim of this study was to evaluate the long-term efficacy of dual-hemisphere repetitive transcranial magnetic stimulation (rTMS) on poststroke aphasia. METHODS(More)
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) applied over left temporoparietal cortex has been reported to have a long-term therapeutic effect on tinnitus. We compare the impact of 1 and 25 Hz rTMS delivered either contralateral or ipsilateral to symptoms in 62 patients with unilateral chronic tinnitus. MATERIAL AND METHODS Patients were(More)
Minimal-invasive, single-port laparoscopic surgery is a recent innovation that may improve surgical outcomes. In this chapter, we review published research on single-port surgery in gynaecology, and the different surgical instruments available. Challenges, advantages, indications and potential future rules of this new approach are also discussed. Sixty-five(More)
BACKGROUND There is a lack of awareness among physicians of the considerable disability caused by non-motor symptoms (NMS) in PD. The aim of this work is to estimate the prevalence of NMS in a series of patients with Parkinson's disease (PD). MATERIALS AND METHODS We studied 112 patients with Parkinson's disease. Motor symptoms were scored on the Unified(More)
AIM Brachial plexus surgery constitutes a long and complex procedure. The aim of our study is to assess the interest of having a double operating team throughout the duration of this surgery. PATIENTS AND METHODS Seventeen patients with brachial plexus palsy underwent surgery operated by a double team. The operating time corresponding to each step of the(More)
There is no consensus in the literature as to the maximum delay for nerve repair following nerve injury. Our aim is to estimate the maximum delay at which a nerve can be successfully reconstructed. Eighteen patients (24 procedures) were operated at more than 12 months (12 to 36) post-injury. Mean age was 38 (17 to 74). There were 18 nerve transfers, four(More)
