[Sacral neuromodulation for bladder voiding dysfunction: Experience at a French university center]. / Neuromodulation sacrée pour trouble de la vidange vésicale : expérience d'un centre universitaire français.

OBJECTIVE: To report the experience of a university hospital center with sacral neuromodulation for patients with bladder voiding disorders. MATERIAL AND METHODS: All patients who underwent sacral neuromodulation between 1998 and 2022 for bladder voiding disorders were included. Medical records were analyzed retrospectively, and population, efficacy and follow-up data were collected. RESULTS: A total of 134 patients underwent test implantation and 122 patients were analyzed. 68 patients (56%) were implanted with a definitive neuromodulation device. Mean age was 43±16 years and BMI 25.5±5.4kg/m2. 74% were women. Bladder voiding disorder was due to sphincter hypertonia in 51% of cases, with associated bladder hypocontractility in 29%. The spontaneous micturition rate after implantation increased from 34% to 92%. Implantation results appeared to be better in patients with sphincter hypertonia, whether or not associated with bladder hypocontractility. The benefit was most often present with a frequency of 5Hz (54.4%). Side-effects were present in 52% of cases at 5 years, and in 85% of cases were pain in relation to the implanted devices. They resolved under medical treatment or after revision of the device (27% of cases at 5 years). CONCLUSION: SNM is effective in micturition recovery, but has side effects. Urodynamic mechanism and etiology may provide clues for modulating NMS box settings and determining predictive factors for NMS success. Data from other centers are needed to identify reliable predictive factors.

The combination of deep breathing and mental imagery promotes cardiovascular recovery in firefighters.

Firefighters' rescue operations involve intense physical activity associated with a high level of cardiovascular stress. To sustain such intense physical performance whilst maintaining a healthy heart, it is crucial that they benefit from rapid recovery between each intervention. This study aimed at investigating the impacts of a recovery protocol combining deep breathing and mental imagery. Forty firefighters were divided into two experimental groups which undertook two maximum fitness tests separated by either the control recovery protocol (30 min reading time; n = 20) or the experimental recovery protocol (30 min of deep breathing and mental imagery; n = 20). When compared to the pre-tests, the percentage evolution ratios in the post-tests for the Cooper performance, the heart rate recovery and the parasympathetic reactivation were promoted by the experimental protocol, compared to simple reading. In light of these results, we propose the use of practices of deep-breathing combined with mental imagery to improve firefighters' recovery. Practitioner summary: Firefighters' activities involve intense physical activities associated with a high level of psychological stress. Enhancing their recovery after each rescue intervention appears crucial. The results of this study showed that a recovery protocol combining deep breathing and mental imagery promotes heart rate recovery and better maintenance of physical fitness.

Use of Malone antegrade continence enemas in neurologic bowel dysfunction.

INTRODUCTION: Patients with neurogenic bowel dysfunction (NBD) suffer severe constipation and/or fecal incontinence that are very difficult to treat. Most medication-based and interventional treatments have been unsuccessful. The goal of this study was to assess the medium-term effectiveness of the Malone procedure in all patients with NBD, as an alternative to colostomy. PATIENTS AND METHODS: In this retrospective single-center study, 23 patients who underwent Malone's surgical treatment were analyzed. The main criteria were the usage of antegrade colonic enemas (ACE) after Malone's procedure at the most recent follow-up and comparison of quality of life scores before and after surgery. RESULTS: The post-procedure mortality was zero, but an overall morbidity of 60% was observed, including minor complications (Clavien 1, 2) in 56%. The median follow-up was 33 months. At the most recent follow-up, the utilization rate of the neo-appendicostomy for ACE was 69.6%; 76.9% of the patients using ACE reported improvement in quality of life scores. Secondary colostomy was performed in 21.7% for functional failure of the Malone procedure. CONCLUSION: The Malone procedure is a reliable technique that can be used in the therapeutic strategy for managing NBD patients with incontinence/constipation refractory to usual treatments. It should be considered as a therapeutic step to take before resorting to colostomy.

Sites of electrical stimulation used in neurology.

Rehabilitation aims to decrease neurological impairments, in guiding plasticity. Electrical stimulation has been used for many years in rehabilitation treatment of neurological disabilities as a tool for neuromodulation inducing plasticity, although the mechanisms of its action are not well known. The applications vary, encompassing therapeutic and rehabilitative aims. The type and site of stimulation vary depending on the objectives. Some techniques are widely used in clinical practice; others are still in the research stage. They may be invasive, epidural or in direct contact with neurons; they may be noninvasive, applied transcutaneously or indirectly by current vectors. The indications vary: mobility, functionality, pain as well as pharyngeal, respiratory, and perineal function. This paper aims to summarize current data on electrical neuromodulation techniques used in neurorehabilitation, their effects and their mechanisms of action.

[Alternative treatments for interstitial cystitis]. / Les traitements de recours dans la cystite interstitielle.

Interstitial cystitis is the first cause of bladder pain. In case of failure of the usual treatments, several other modalities have been proposed. These therapeutic modalities are posterior sacral root neuromodulation, posterior tibial nerve stimulation, vanilloid agent intravesical instillation, intradetrusor botulinum toxin injections and surgery. A certain efficiency of each of these treatments in the interstitial cystitis has been reported. However, the evaluation of these treatments is limited and the level of evidence is too low to propose these treatments in routine.

Neural correlates of proprioceptive integration in the contralesional hemisphere of very impaired patients shortly after a subcortical stroke: an FMRI study.

BACKGROUND: The effects of physiotherapy are difficult to assess in very impaired early stroke patients. OBJECTIVE: The aim of the study was to characterize the impact of 4 weeks of passive proprioceptive training of the wrist on brain sensorimotor activation after stroke. METHODS: Patients with a subcortical ischemic lesion of the pyramidal tract were randomly assigned to a control or a wrist-training group. All patients had a single pure motor hemiplegia with severe motor deficit. The control group (6 patients) underwent standard Bobath rehabilitation. The second, "trained," group (7 patients) received Bobath rehabilitation plus 4 weeks of proprioceptive training with daily passive calibrated wrist extension. Before and after the training period, patients were examined with validated clinical scales and functional MRI (fMRI) while executing a passive movement versus rest. The effect of standard rehabilitation on sensorimotor activation was assessed in the control group on the wrist, and the effect of standard rehabilitation plus proprioceptive training was assessed in the trained group. The effect of 4-week proprioceptive training alone was statistically evaluated by difference between groups. RESULTS: Standard rehabilitation along with natural recovery mainly led to increases in ipsilesional activation and decreases in contralesional activation. On the contrary, standard rehabilitation and paretic wrist proprioceptive training increased contralesional activation. Proprioceptive training produced change in the supplementary motor area (SMA), prefrontal cortex, and a contralesional network including inferior parietal cortex (lower part of BA 40), secondary sensory cortex, and ventral premotor cortex (PMv). CONCLUSION: We have demonstrated that purely passive proprioceptive training applied for 4 weeks is able to modify brain sensorimotor activity after a stroke. This training revealed fMRI change in the ventral premotor and parietal cortices of the contralesional hemisphere, which are secondary sensorimotor areas. Recent studies have demonstrated the crucial role of these areas in severely impaired patients. We propose that increased contralesional activity in secondary sensorimotor areas likely facilitates control of recovered motor function by simple proprioceptive integration in those patients with poor recovery.
