RESUMEN

PURPOSE: To investigate efficiency and tolerance of transcutaneous tibial nerve stimulation (TNS) in the overactive bladder syndrome in patients with Parkinson's disease (PD), and to identify predictive factors for compliance. METHODS: We conducted a retrospective monocentric study with a cohort of 17 patients with PD who have used TNS for an overactive bladder syndrome. The efficiency of the treatment was evaluated on the clinical improvement felt (rated out of ten). Patients were classified as « adopters ¼ if they continued using TNS for at least one year after beginning the treatment or as « non adopters ¼ if they stopped. Patients characteristics were evaluated for their predictive value for compliance with TNS. RESULTS: Out of 17 patients, there were 9 women and 8 men, median age 66 years (55-77), median history for Parkinson's disease 8 years (1-22) and for urinary symptoms 3 years (1-10). Subjective efficiency was seen in 10 patients (59%), on nocturia and/or urinary incontinence for 9 patients (mean efficiency 5.75/10 and median efficiency 6.5/10). Three patients found TNS not effective, and four patients didn't use it long enough to evaluate. Two patients had side effects and stopped the TNS (feeling of electricity and restless leg syndrome). 7 patients were classified as « adopters ¼ and 10 patients as « non adopters ¼ after one year. Most evaluated characteristics proved not to be of predictive value for compliance with TNS except nocturia and pollakiuria (P=0.03 and P=0.05). CONCLUSION: Our study seems to reveal TNS is particularly effective on nocturia and urge. Moreover, nocturia and pollakiuria appear to be predictive factors for SNT compliance. Nocturia could be a prominent symptom in SNT's prescription. But studies with more patients should be conducted for obtain better patient selection in TNS. LEVEL OF EVIDENCE: IV.

RESUMEN

OBJECTIVE: To highlight the existence of pseudo-dyssynergia in Idiopathic Parkinson's Disease (IPD) constituting a functional bladder outlet obstruction. MATERIALS AND METHODS: A retrospective study was conducted by including men with a confirmed diagnose of IPD who participated in the SIROCCO rehabilitation program. Patients included clinically exhibited overactive bladder and voiding dysfunction without prostatic hypertrophy ultrasounded. They have been clinically assessed by the Urinary Symptoms Profile (USP) urinary symptom score. Bladder outlet obstruction was assessed by the pressure-flow study. Urodynamic obstruction has been quantified by the bladder obstruction index which depends on detrusor pressure at maximum flow rate and maximum flow rate. It has been defined by a BOOI>40. RESULTS: The pressure-flow profile was analyzed in 5 patients who met the inclusion criteria. In this group of 5 patients with IPD, the diagnosis was made on average 10.6 years (7-14) before the pressure-flow studies were performed. Our results objectified 4 patients obstructive among 5 and one equivocal patient. A striated pseudo-dyssynergia was found in the 3 obstructive patients and associated with a smooth pseudodyssynergia in one patient. CONCLUSION: We have observed, in this short series, a pseudo-dyssynergia by subjects suffering from IPD. LEVEL OF EVIDENCE: 3.

RESUMEN

Unilateral spatial neglect constitutes a heterogeneous syndrome characterized by two main entangled components: a contralesional bias of spatial attention orientation; and impaired building and/or exploration of mental representations of space. These two components are present in different subtypes of unilateral spatial neglect (visual, auditory, somatosensory, motor, allocentric, egocentric, personal, representational and productive manifestations). Detailed anatomical and clinical analyses of these conditions and their underlying disorders show the complexity of spatial cognitive deficits and the difficulty of proposing just one explanation. This complexity is in contrast, however, to the widely acknowledged effectiveness of rehabilitation of the various symptoms and subtypes of unilateral spatial neglect, exemplified in the case of prism adaptation. These common effects are reflections of the unity of the physiotherapeutic mechanisms behind the higher brain functions related to multisensory integration and spatial representations, whereas the paradoxical aspects of unilateral spatial neglect emphasize the need for a greater understanding of spatial cognitive disorders.

RESUMEN

BACKGROUND: The aim of this study was to assess the impact of medico-pharmaceutical partnership on the quality of antibiotic treatment in urinary tract infection (UTI) within rehabilitation center. MATERIAL: All antibiotic prescriptions were validated by the pharmacist at the start of treatment and twice a week. All patients with symptomatic urinary tract infection between January 1, 2014 to December 31, 2015 were included in this study. Addition to awareness among specifiers to promoting the appropriate use of antibiotics, the pharmacist suggested pharmaceutical interventions (PI) in order to improve the quality of antibiotic treatments. At the same time, 3 quality indicators (QI) were followed: duration, dosage, antibiotic susceptibility. The compliance rates of this 3 QI allowed to assess the quality of the antibiotic treatment in urinary tract infection. RESULTS: The study population included 154 patients corresponding to 252 UTI. Sixty-eight PI were made by pharmacist about urinary tract infection treatment (overdosage or under-dosing, duration unknown, inadequate route of administration). These QI achieved 96.4% compliance with duration, 98.8% compliance with dosage and 99.2% with the antibiotic susceptibility. CONCLUSION: This study allowed showing the medico-pharmaceutical impact on the quality of antibiotic treatments in UTI. The awareness among specifiers with a daily validation of prescription by the pharmacist allowed to improve urinary tract infections care in rehabilitation center. LEVEL OF EVIDENCE: 4.

RESUMEN

Patients in locked-in syndrome show normal or near normal mental abilities that contrast with the limited motor capacity that hinders voluntary communication. However, eye movements and blinking are usually preserved and can be used to establish a communication system. We report an exceptional case of locked-in syndrome. The aetiology was basilar thrombosis consecutive to a cervical manipulation. In addition, brain MRI performed 23 years later showed a ventral pontine stroke with bilateral corticopontic degeneration. In this study the patient was able to produce written output using a chin-controlled Morse system decoded by a computer. A detailed linguistic analysis of text written over 20 years by the patient was carried out. The data demonstrate that improvements in language performance can be observed even in patients with brain lesions in areas associated with high-level cognitive processes. The data show a decrease of typing, grammatical and lexical errors over time, use of less frequent words, and an increase of more complex linguistic structures. This paper adds to previous findings confirming the value of daily practice and rehabilitation to enhance quality of life in this group of patients.

RESUMEN

OBJECTIVE: More and more women with spinal cord injury (SCI) can have a pregnancy. Few data have been published on these pregnancies and their urological impact. We report a series of these cases illustrating the urological experience of specialized centers. METHODS: This is a retrospective study that identified pregnancies in women with SCI followed-up between 2000 and 2014. Data covering all urological and obstetric events during pregnancies, before and after implementation of weekly oral cyclic antibiotics (WOCA) program, were collected from medical records. RESULTS: Fifteen women with SCI who gave birth to 20 children were included. Three of them were quadriplegics and 12 were paraplegics. All of them performed themselves intermittent catheterization: 11 by urethral way and 4 by high way because carrying a continent cystostomy. Mean follow-up period before pregnancy was 14.6 years [3-27 years IC 95%] and the mean follow-up for the study was 8.5 months [6.5-9 IC 95%]. We observed a reduction of symptomatic urinary tract infections after WOCA onset (13/13 before vs. 0/7 after, P=0.001), a reduction of recurrent urinary infections (6/13 vs. 0/7, P=0.03), a reduction of threats to premature births (8/13 vs. 0/7, P=0.001). Multi-resistant bacteria appeared to increase (0/13 vs. 3/7, P=0.01). We also observed a trend to significant reduction of premature births number (4/13 vs. 0/13, P=0.1) and that of low birth weight (3/13 versus 0/7, P=0.1). The overall neonatal survival rate was 100%. CONCLUSION: Our study before/after introduction of a weekly oral cycle antibiotic prophylaxis during pregnancy for women with spinal cord injury showed a significant reduction in symptomatic urinary tract infections and a tendency to improve pregnancy outcomes. LEVEL OF EVIDENCE: 4.

RESUMEN

OBJECTIVES: To assess the impact of endo-urethral stent (EUP) of incontinentation in spinal cord injured (SCI) men on ejaculation capacity. FIRST CRITERIA: Presence of ejaculation after EUP. SECONDARY CRITERIA: Modification on ejaculation type, stimulation mode, possibility of sperm conservation in the same population. POPULATION AND METHODS: A descriptive monocentric study including SCI subjects which underwent placement or change of temporary (Mémokath™ or Allium™) or definitive (Mémotherm™) EUP between January 2004 and January 2014 with at least one ejaculatory test. Are identified for each patient: the presence of ejaculation, type of ejaculation, stimulation mode used, number of frozen specimen and results from semen analysis. RESULTS: Over 11 men with tetraplegia, complete for motricity, there were 8 (72%) for whom ejaculation was possible after laying EUP. Of these, 6 (55%) had an antegrade or antero-retrograde ejaculation. It was not possible to make a freezing straw in four of them due to infection of semen (2) or terato-oligo-astenospermia (1) or absence of reproductive project (1). CONCLUSION: In this small sample, it was found that over 70% ejaculation have been preserved after laying EUP and more than 50% with antegrade or antero-retrograde ejaculation. A larger study would identify how EUP may alter the ejaculatory capacity or quality of the ejaculate. LEVEL OF EVIDENCE: 4.

RESUMEN

STUDY DESIGN: Descriptive control case study. OBJECTIVES: To analyze the kinematics of tenodesis grasp in participants with C6 quadriplegia and healthy control participants in a pointing task and two daily life tasks involving a whole hand grip (apple) or a lateral grip (floppy disk). SETTING: France. METHODS: Four complete participants with C6 quadriplegia were age matched with four healthy control participants. All participants were right-handed. The measured kinematic parameters were the movement time (MT), the peak velocity (PV), the time of PV (TPV) and the wrist angle in the sagittal plane at movement onset, at the TPV and at the movement end point. RESULTS: The participants with C6 quadriplegia had significantly longer MTs in both prehension tasks. No significant differences in TPV were found between the two groups. Unlike control participants, for both prehension tasks the wrist of participants with C6 quadriplegia was in a neutral position at movement onset, in flexion at the TPV, and in extension at the movement end point. CONCLUSION: Two main kinematic parameters characterize tenodesis grasp movements in C6 quadriplegics: wrist flexion during reaching and wrist extension during the grasping phase, and increased MT reflecting the time required to adjust the wrist's position to achieve the tenodesis grasp. These characteristics were observed for two different grips (whole hand and lateral grip). These results suggest sequential planning of reaching and tenodesis grasp, and should be taken into account for prehension rehabilitation in patients with quadriplegia.

RESUMEN

STUDY DESIGN: A case study. OBJECTIVE: The aim was to investigate whether motor imagery (MI) could be successfully incorporated into conventional therapy among individuals with spinal cord injury (SCI) to improve upper limb (UL) function. SETTING: The Physical Medicine and Rehabilitation Unit at the Henry Gabrielle Hospital in Lyon, France. METHODS: The participant was an individual with a complete C6 SCI. MI content was focused on functional UL movements, to improve hand transport to reach out and grasp with tenodesis. The participant was tested before and after 15 MI training sessions (45 min each, three times a week during 5 consecutive weeks). MI ability and program compliance were used as indicators of feasibility. The Minnesota and Box and Blocks tests, as well as movement time and hand trajectory during targeted movements were the dependent variables, evaluating motor performance before and after MI training. RESULTS: The participant's ability to generate MI was checked and compliance with the rehabilitation program was confirmed. The time needed to complete the Minnesota test decreased by 1 min 25 s. The Box and Blocks score was improved by three units after MI program. Decreased movement time and enhanced hand trajectory smoothness were still observed 3 months later, despite a slight decrease in performance. CONCLUSIONS: This study supports the feasibility for introducing MI in conventional therapy. Further studies should confirm the potential role of MI in motor recovery with a larger sample.

RESUMEN

OBJECTIVES: Hereditary spastic paraplegia (HSP) is a degenerative central nervous system disorder characterized by progressive spasticity and hyperreflexia of the lower limbs. Often, patients with HSP experience symptoms of voiding dysfunction. Urodynamic evaluations of these patients are rarely reported in the literature and the etiology of voiding dysfunction remains unclear. The present study characterizes lower urinary tract dysfunction in a large series of patients. METHODS: The medical records of 29 HSP patients who underwent urodynamic evaluation were retrospectively analyzed. The history of lower urinary tract symptoms was noted and the urodynamic findings analyzed. RESULTS: Urgency was the most dominant complaint (72.4%), followed by frequency (65.5%), urinary incontinence (55.2%) and hesitancy (51.7%). The urodynamic findings showed signs of central neurogenic bladder in 24 patients (82.7%), with detrusor overactivity (DO) in 15 patients (51.7%) and detrusor sphincter dyssynergia (DSD) in 19 (65.5%). Post-void residual (PVR) of >10% of the voided volume was found in 12 patients (41.4%). There were significant relationships between detrusor overactivity and PVR (P=0.005), frequency (P=0.046) and nocturia (P=0.045). Ultrasound examination revealed no upper urinary tract complications. CONCLUSION: Despite the presence of DO and DSD, HSP patients do not seem to have a high risk of developing ultrasonographically-assessed upper urinary tract complications after a mean follow-up of 22 years, contrary to spinal cord injury population. These results may guide practitioners in their decision-making about the appropriate evaluation and treatment of bladder disturbances that accompany hereditary spastic paraplegia.

RESUMEN

OBJECTIVE: Bowel dysfunction and disordered defecation are very common after spinal cord injury (SCI) and can have a major impact on patients' social life and quality of life. The aim of this study was to assess the safety and efficacy of transanal irrigations (TAI) in the management of Bowel dysfunction in SCI patients. METHODS: Forty-five consecutive SCI patients using TAI were retrospectively included. TAI efficacy was assessed through Neurogenic Bowel Dysfunction (NBD) score recorded before and after 8 weeks of regular use. Possible side effects were assessed with a semi-structured questionnaire. Patients who started TAI use at least 6 months previously were contacted to assess long-term compliance, efficacy and safety of TAI. RESULTS: After 8 weeks of regular use of TAI, the average NBD scores decreased by four points (P<0.0001) with a specific improvement in the items related to stool frequency (P: 0.036), occurrence of malaise, headache, or sweating during defecation (P: 0.043), use of drugs against constipation (P: 0.007) and frequency of fecal incontinence (P: 0.001). The main side effects were bleeding (10%) and abdominal pain (8%). At 6 months, 80% of the assessed patients had continued regular use of TAI with no particular problem. CONCLUSION: This study showed good medium and long-term efficacy and safety of TAI in the management of bowel dysfunction and defecation disorders in spinal cord-injured patients.

RESUMEN

Unilateral neglect is a disabling syndrome frequently observed following right hemisphere brain damage. Symptoms range from visuo-motor impairments through to deficient visuo-spatial imagery, but impairment can also affect the auditory modality. A short period of adaptation to a rightward prismatic shift of the visual field is known to improve a wide range of hemispatial neglect symptoms, including visuo-manual tasks, mental imagery, postural imbalance, visuo-verbal measures and number bisection. The aim of the present study was to assess whether the beneficial effects of prism adaptation may generalize to auditory manifestations of neglect. Auditory extinction, whose clinical manifestations are independent of the sensory modalities engaged in visuo-manual adaptation, was examined in neglect patients before and after prism adaptation. Two separate groups of neglect patients (all of whom exhibited left auditory extinction) underwent prism adaptation: one group (n = 6) received a classical prism treatment ('Prism' group), the other group (n = 6) was submitted to the same procedure, but wore neutral glasses creating no optical shift (placebo 'Control' group). Auditory extinction was assessed by means of a dichotic listening task performed three times: prior to prism exposure (pre-test), upon prism removal (0 h post-test) and 2 h later (2 h post-test). The total number of correct responses, the lateralization index (detection asymmetry between the two ears) and the number of left-right fusion errors were analysed. Our results demonstrate that prism adaptation can improve left auditory extinction, thus revealing transfer of benefit to a sensory modality that is orthogonal to the visual, proprioceptive and motor modalities directly implicated in the visuo-motor adaptive process. The observed benefit was specific to the detection asymmetry between the two ears and did not affect the total number of responses. This indicates a specific effect of prism adaptation on lateralized processes rather than on general arousal. Our results suggest that the effects of prism adaptation can extend to unexposed sensory systems. The bottom-up approach of visuo-motor adaptation appears to interact with higher order brain functions related to multisensory integration and can have beneficial effects on sensory processing in different modalities. These findings should stimulate the development of therapeutic approaches aimed at bypassing the affected sensory processing modality by adapting other sensory modalities.

RESUMEN

A well-known theory in the field of attention today is the premotor theory of attention which suggests that the mechanisms involved in eye movements are the same as those for spatial attention shifts. We tested a parietal damaged patient with unilateral optic ataxia and 4 controls on a dual saccade/attentional task and show a dissociation between saccadic eye movements and presaccadic perceptual enhancement at the saccade goal. Remarkably, though the patient was able to make the appropriate saccades to the left, impaired visual field (undistinguishable from saccades to his right, intact visual field), he was unable to discriminate the letter at the saccade goal (whereas his performance was like controls for letter discrimination in his right visual field). This suggests that saccade planning and presaccadic perceptual facilitation are separable--planning a saccade to a location does not necessitate that the processing of this location is enhanced. Based on these results, we suggest that the parietal cortex is necessary for the coupling between saccade planning and presaccadic perceptual facilitation.

RESUMEN

We designed a protocol distinguishing between automatic and intentional motor reactions to changes in target location triggered at movement onset. In response to target jumps, but not to a similar change cued by a color switch, normal subjects often could not avoid automatically correcting fast aiming movements. This suggests that an 'automatic pilot' relying on spatial vision drives fast corrective arm movements that can escape intentional control. In a patient with a bilateral posterior parietal cortex (PPC) lesion, motor corrections could only be slow and deliberate. We propose that 'on-line' control is the most specific function of the PPC and that optic ataxia could result from a disruption of automatic hand guidance.

RESUMEN

OBJECTIVES: For hospitalizations in rehabilitation centers (RCs) in France, the quantification of healthcare givers' activity is based on the dependency of the patients, defined as a total or partial inability to perform activities required for daily living without help. The tools currently used to quantify dependency are not sufficiently precise. Here we describe the construction of a new tool, the SOFMER Activity Score (SAS scoring), which allows for a good description of the level of activity of patients hospitalized in RCs, and a feasibility study of the tool. METHODS: After a study group proposed the first version of the SAS, the validity of its content was studied by the Delphi consensus method: 26 physicians or healthcare professionals known for their expertise in PMR responded to the first round. The feasibility study was prospective and involved multi-site professionals. Data related to the SAS determined by a multidisciplinary team were collected and compared to the Activité de la Vie Quotidienne (AVQ) scale, which is administered to all patients and included in medical and administrative data. RESULTS: We included 81 patients in the feasibility study. The mean (SD) time to obtain the SAS was 4.5 (3.3) min. For 97.5% of scorings, the participating professionals judged that the SAS was compatible or fairly compatible with clinical practice. The internal structure of the SAS scale seemed better than that of the AVQ scale, for which the present study confirmed a floor effect for all items. CONCLUSIONS: The SAS allows for measuring the level of physical and cognitive activity of a patient hospitalized in an RC. If validation studies for the SAS, exploring its reliability, construct validity or criterion validity, confirm the tool's good metrological qualities, the SAS will allow for a good quantification of the burden of care.

RESUMEN

Left-hemiparetic patients show predominant postural imbalance as compared to right-hemiparetic patients. The right hemisphere is crucial for generating internal maps used for perceptual and premotor processing of spatial information. Predominant postural imbalance with right-brain damage could thus result from a distortion of an internal postural map. Well-known manifestations of distorted internal maps due to right-hemisphere lesions, such as hemineglect, may show improvement following prism adaptation shifting the visual field to the right. We therefore investigated the effect of prism adaptation on postural imbalance in left-hemiparetic patients. Three groups of five patients were either adapted to prisms deviating the visual field to the right or left or exposed to neutral prisms while performing reaching movements of the right arm. Postural imbalance was reduced only following prism adaptation to the right. Thus, brief adaptation (i.e., 3 min) to rightward-shifting prisms can dramatically improve postural imbalance. This result shows that the effect of exposure to prisms that horizontally shift the visual field to the right in a reaching task generalizes to the postural system, and it suggests an interaction between horizontal and vertical reference frames. This also supports the theory that predominant postural imbalance in patients with right-brain damage may be partly related to a distortion of an internal postural map.

RESUMEN

The objective of this review is to reinstate the diversity of visual perception and visuomotor symptoms following lesions to the posterior parietal cortex (dorsal visual stream). This diversity was overshadowed for a long time and shows the contribution of the dorsal visual stream not only to action but also to perception. More precisely, we propose that the visuomotor deficit in optic ataxia stems from two distinct components: visual proprioceptive deficit (hand effect) and visual attentional deficit (field effect) also affecting the perception in peripheral vision.

RESUMEN

Hemispatial neglect is a common disabling condition following brain damage to the right hemisphere. Generally, it involves behavioral bias directed ipsilaterally to the damaged hemisphere and loss of spatial awareness for the contralesional side. In this syndrome, several clinical subtypes were identified. The objective of this article is to provide a nosological analysis of the recent data from the literature on the different subtypes of neglect (visual, auditory, somatosensory, motor, egocentric, allocentric and representational neglect), associated ipsilesional and contralesional productive manifestations and their anatomical lesion correlates. These different anatomical-clinical subtypes can be associated or dissociated. They reflect the heterogeneity of this unilateral neglect syndrome that cannot be approached or interpreted in a single manner. We propose that these subtypes result from different underlying deficits: exogenous attentional deficit (visual, auditory neglect); representational deficit (personal neglect, representational neglect, hyperschematia); shift of the egocentric reference frame (egocentric neglect); attentional deficit between objects and within objects (allocentric neglect), endogenous attentional deficit (representational neglect) and transsaccadic working memory or spatial remapping deficit (ipsilesional productive manifestations). Taking into account the different facets of the unilateral neglect syndrome should promote the development of more targeted cognitive rehabilitation protocols.

RESUMEN

INTRODUCTION: Stroke frequently results in balance disorders, leading to lower levels of activity and a diminution in autonomy. Current physical therapies (PT) aiming to reduce postural imbalance have shown a large variety of effects with low levels of evidence. The objectives are to determine the efficiency of PT in recovering from postural imbalance in patients after a stroke and to assess which PT is more effective. METHODS AND ANALYSIS: We will search several databases from inception to October 2015. Only randomised controlled trials assessing PT to recover from poststroke postural imbalance in adults will be considered.Outcome measures will be the Berg Balance Scale (BBS), the Postural Assessment Scale for Stroke (PASS), the 'weight-bearing asymmetry' (WBA), the 'centre of pressure' (COP) and the 'limit of stability' (LOS). WBA, COP and LOS are measured by a (sitting or standing) static evaluation on force plate or another device.Two independent reviewers will screen titles, abstracts and full-text articles, evaluate the risk of bias and will perform data extraction. In addition to the outcomes, measures of independence will be analysed. This study will aim at determining the effects of PT on the function (WBA, COP, LOS), the activity (BBS, PASS) and the independence of patients. Subgroup analyses will be planned according to the location of brain lesion (hemispheric, brainstem or cerebellum), the time since stroke (early, late, chronic), the PT (type, main aim (direct effect or generalisation), overall duration), the type of approaches (top-down or bottom-up) and the methodological quality of studies. ETHICS AND DISSEMINATION: No ethical statement will be required. The results will be published in a peer-reviewed journal. This meta-analysis aims at managing the rehabilitation after postural imbalance by PT after a stroke. TRIAL REGISTRATION NUMBER: Prospero CRD42016037966;Pre-results.

RESUMEN

Visuo-manual adaptation to prisms produces a long-lasting improvement of visuo-spatial neglect. Improvement is also observed in tasks that do not involve visuo-manual component and that can all be consider to rely on a rightward (ipsilesional) orienting bias. Here, we report positive effects of prism adaptation on spatial dysgraphia, in a neglect patient following right brain damage. A long-lasting improvement concerned the right-page preference reflecting the ipsilesional bias but also the sloping lines and the broken lines reflecting visuo-constructive disorders in handwriting. Moreover, a transient improvement was also evidenced for the graphic errors. These results reinforce the idea that the process of prism adaptation may activate brain functions related to multisensory integration and higher spatial representations and show a generalization at a functional level. Prism adaptation therefore appears as useful tool in the theoretical attempt to identify the underlying 'core' mechanisms of the neglect syndrome.
