RESUMEN
OBJECTIVE: The objective of this study was to evaluate users' driving performances with a Power Wheelchair (PWC) driving simulator in comparison to the same driving task in real conditions with a standard power wheelchair. METHODS: Three driving circuits of progressive difficulty levels (C1, C2, C3) that were elaborated to assess the driving performances with PWC in indoor situations, were used in this study. These circuits have been modeled in a 3D Virtual Environment to replicate the three driving task scenarios in Virtual Reality (VR). Users were asked to complete the three circuits with respect to two testing conditions during three successive sessions, i.e. in VR and on a real circuit (R). During each session, users completed the two conditions. Driving performances were evaluated using the number of collisions and time to complete the circuit. In addition, driving ability by Wheelchair Skill Test (WST) and mental load were assessed in both conditions. Cybersickness, user satisfaction and sense of presence were measured in VR. The conditions R and VR were randomized. RESULTS: Thirty-one participants with neurological disorders and expert wheelchair drivers were included in the study. The driving performances between VR and R conditions were statistically different for the C3 circuit but were not statistically different for the two easiest circuits C1 and C2. The results of the WST was not statistically different in C1, C2 and C3. The mental load was higher in VR than in R condition. The general sense of presence was reported as acceptable (mean value of 4.6 out of 6) for all the participants, and the cybersickness was reported as acceptable (SSQ mean value of 4.25 on the three circuits in VR condition). CONCLUSION: Driving performances were statistically different in the most complicated circuit C3 with an increased number of collisions in VR, but were not statistically different for the two easiest circuits C1 and C2 in R and VR conditions. In addition, there were no significant adverse effects such as cybersickness. The results show the value of the simulator for driving training applications. Still, the mental load was higher in VR than in R condition, thus mitigating the potential for use with people with cognitive disorders. Further studies should be conducted to assess the quality of skill transfer for novice drivers from the simulator to the real world.

OBJECTIVES: The objective of this study is to highlight the effect of a robotic driver assistance module of powered wheelchair (PWC), using infrared sensors and accessorizing a commercial wheelchair) on the reduction of the number of collisions in standardized circuit in a population with neurological disorders by comparing driving performance with and without assistance. METHODS: This is a prospective, single-center, controlled, repeated measure design, single-blind pilot study including patients with neurological disabilities who are usual drivers of electric wheelchairs. The main criterion for evaluating the device is the number of collisions with and without the assistance of a prototype anti-collision system on three circuits of increasing complexity. Travel times, cognitive load, driving performance, and user satisfaction are also analyzed. RESULTS: 23 Patients, 11 women and 12 men with a mean age of 48 years old completed the study. There was a statistically significant reduction in the number of collisions on the most complex circuit: 61% experienced collisions without assistance versus 39% with assistance (p = 0.038). CONCLUSION: This study concludes that the PWC driving assistance module is efficient in terms of safety without reducing the speed of movement in a population of people with disabilities who are habitual wheelchair drivers. The prospects are therefore to conduct tests on a target population with driving failure or difficulty who could benefit from this device so as to allow them to travel independently and safely.

Despite progress in the prevention of pressure injuries (PIs), they remain a challenging public health problem because of their frequency and morbidity. Protection of the skin by multilayer silicone foam dressings may be an adjuvant measure to prevent PIs in high-risk patients. Despite the available clinical data and published recommendations on this measure, caregivers face difficulties in identifying patients who would benefit from this adjuvant measure. The objective of this work was to define the profiles of high-risk patients who would benefit optimally from this measure in combination with basic preventive procedures. This consensual expert opinion was drawn up using two methods: the Nominal Group Technique with eight medical and paramedical experts, and the Delphi process with 16 experts. The bases for this expert consensual opinion were a formal search and analysis of the published literature regarding evidence on the prevention of PIs using multilayer silicone foam dressings. The consensual expert opinion reported here addresses five proposals mostly intended to define patients who would benefit from the use of a multilayer silicone foam dressing (≥4 layers) to prevent PIs (sacrum and heels).

OBJECTIVE: To evaluate medication, rehabilitation and healthcare consumption in adults with CP as a function of Gross Motor Function Classification System (GMFCS) level. DESIGN: Questionnaire-based cross-sectional study. SETTING: Brittany, a French county. SUBJECTS: Adults with cerebral palsy. INTERVENTIONS: Questionnaires relating to drugs, orthotic devices, mobility aids, rehabilitation and medical input were sent to 435 members of a unique regional French network dedicated to adults with cerebral palsy. The questionnaire was completed by the participant or a helper if necessary. RESULTS: Of the 282 responders, 7.8% had a GMFCS level of I, 14.2% II, 17.7% III, 29.1% IV and 31.2% V. Participants consumed a large amount of healthcare. Almost three-quarters took orally administered drugs, of which antispastic and antiepileptic drugs were among the most frequent. Nearly all patients had at least one type of rehabilitation, 87.2% had physiotherapy, 78% used at least one mobility aid and 69.5% used at least one orthotic device. The frequency of numerous inputs increased with GMFCS level. Specificities were found for each GMFCS level, e.g. participants with GMFCS level IV and V had a high level of medical input and a greater use of trunk-supporting devices, antireflux and laxative. Profiles could be established based on GMFCS levels. CONCLUSIONS: Adults with cerebral palsy use a large amount of drugs, mobility aids, orthotic devices, rehabilitation and medical input. Healthcare is targeted at cerebral palsy-related issues. GMFCS is a determinant of healthcare consumption and thus a useful tool for clinical practice to target care appropriately.

PURPOSE: In France, tens of thousands of people use a wheelchair. Driving powered wheelchairs (PWCs) present risks for users and their families. The risk of collision in PWC driver increases with severity of disability and may reduce their independence to drive. The European ADAPT project has developed a robotic assistance add-on for PWCs to prevent collisions and improve their driving performance. MATERIALS AND METHODS: The aim of the SWADAPT2 study is to assess the benefit of this robotic assistance add-on arranged on a Standard Quickie Salsa M2 PWC in a population of PWC drivers with neurological disorders and driving difficulties. Eighteen (18) participants tested the system on three circuits of increasing difficulty, with and without the robotic assistance add-on. RESULTS: The benefit of the robotic assistance add-on was important especially on the more difficult circuits without impacting cognitive load or driving speed. The number of collisions was significantly reduced when using robotic assistance add-on from 2.16 to 0.36 on circuit 2 (p = 0.009) and from 7.3 to 1.33 on circuit 3 (p = 0.0009). Task load demand was not increased with the assistance. CONCLUSION: Finally, this system seems to be indicated to assist and improve driving safety for PWC drivers in driving difficulty. Evaluation was performed in controlled environments; therefore, further evaluation in real-world scenarios is needed to reach technology readiness.
â¢This device is an effective technology to avoid collisions, especially for patients with neurological disorders in difficulty of driving.â¢Several use cases can be considered:the equipment of drivers who are losing driving ability due to age evolution of their pathology, or anxietythe equipment of users in driving training with difficulties, in order to facilitate access to users who are currently unable to drive.
RESUMEN
PURPOSE: To adapt the Moorong Self-Efficacy Scale (MSES) in the French language and determine its psychometric proprieties. MATERIALS AND METHODS: After a back-translation process, an expert committee was solicited to develop the French Self Efficacy Scale, thanks to a Delphi method, regarding theoretical framework and concepts explored. A total of 201 patients with SCI were included to explore internal consistency, internal and external structure validity assessed with the General Self-Efficacy scale, MOS Health Survey Short-Form, Hospital Anxiety and Depression Scale, Way of Coping Check-list, Perceived Stress Scale, Social Support Questionnaire, Self-Esteem questionnaire, and Satisfaction With Life Scale. The retest was performed 4 days later with a randomized version of the MSES-Fr. RESULTS: The 16 items are distributed in 3 different dimensions: Interpersonal Self-Efficacy (4 items), Instrumental Self-Efficacy (4 items) and Participation Self-Efficacy (6 items). The internal consistency was excellent (Cronbach α = .87). Results evidenced significant correlations with the MSES-Fr and other related psychological constructs (self-esteem, mood, quality of life). Reproducibility was good for the total score of the MSES-Fr (ICC = .74) and for the 3 dimensions of the scale. CONCLUSIONS: The MSES-Fr is a valid and reliable tool to assess self-efficacy in persons with spinal cord injury.Implications for rehabilitationThe Moorong Self-Efficacy Scale (MSES) is commonly used in persons with SCI for evaluating the level of perceived effectiveness in living with a disability.Validity and reliability studies of the MSES-Fr show good psychometrics properties in people with SCI.The French version of the MSES has been cross-culturally translated and is ready to be used clinically.

BACKGROUND: Parkinson disease is a neurodegenerative disease causing a progressive loss of autonomy. This requires long-term rehabilitation care. Currently, new technologies are being developed for use in daily life, and there is a progressive implementation of telerehabilitation. OBJECTIVE: The aim of this study (the TELEP@RK study) is to evaluate the uses of a digital self-rehabilitation device in patients with Parkinson disease and their independent physiotherapists on the scale of a health territory. METHODS: A total of 10 independent physiotherapists and 31 patients with Parkinson disease were followed for 1 year to evaluate the use of a telerehabilitation tool (digital tablet and inertial sensor) via questionnaires of the Unified Theory of Acceptance and Use of Technology (UTAUT). The questionnaires were submitted to participants at 0, 2, and 12 months from the start of follow-up. The averages of the scores of the different determinants and constructs of the UTAUT questionnaires were compared at the different follow-up times. RESULTS: Among professionals, the averages of the various determinants were generally high at the beginning of the study with an average (out of 5) performance expectancy of 4.19, effort expectancy of 3.88, social influence of 3.95, facilitating conditions of 4, and intention to use of 3.97. These averages decreased over time. CONCLUSIONS: Acceptability, acceptance, and appropriation of the tool were very high among the physiotherapists as well as the patients, despite the tool's lack of evolution during the study. In the current health care context, these results allow us to envision a new organization of the care pathway for patients with chronic diseases, with the increased use of new technologies associated with telecare.
RESUMEN
UNLABELLED: We herein report five cases of cerebral palsy athetosic patients with spondyloid cervical myelopathy. Four of them underwent decompressive surgery. The level of cervicarthrosis differs from a control population with a more frequent osteoarthritis on the lower cervical spine. The diagnosis of spondylotic cervical myelopathy is frequently overlooked because of the insidious progression of neurologic disorders and of the pre-existent neurological handicap. Depressive syndrome is often evoked in such a situation, and thus responsible for a delay of diagnosis. The presence of an hypersignal in T2 MRI sequences is still controversial. For some authors it is an indication for surgery, which is the treatment with the best functional results. CONCLUSION: Cervical spondylotic myelopathy must be evoked in patients with athetoid cerebral palsy who complain about a decrease of their functional ability.

OBJECTIVE: To report a case illustrating the usefulness of botulinum toxin A in the treatment of spinal dystonia responsible for low back pain and postural disorders. METHODS: Critical appraisal of a case report. CASE REPORT: A young woman with cerebral palsy had lumbar paraspinal muscle dystonia responsible for pain and hyperlordosis unresponsive to oral medications for muscle spasm. Botulinum toxin A (Botox(R), 200 U) was injected into the paraspinal muscles at six sites, to good effect. DISCUSSION: The few reported cases consistently show a favorable effect of local botulinum toxin A injections in patients with painful paraspinal muscle dystonia related to neurological disease or chronic low back pain. CONCLUSION: Botulinum toxin A may be a useful treatment for incapacitating painful dystonia of the paraspinal muscles. This treatment improves posture in the sitting position and facilitates the fitting of orthotic devices. Furthermore, botulinum toxin A treatment may help to determine whether an intrathecal baclofen test is in order.

We have studied the recovery of walking ability on being discharged from a department of physical medicine and rehabilitation in patients with hemiplegia after stroke, and the factors influencing this recovery. This prospective study was based on 93 patients. The patients, who were considered to be ambulatory, were able to move 10 metres on their own or with supervision when they were discharged. The potentially influential factors studied were: age, the aetiology and the side of hemiplegia, co-morbidity, the delay in starting rehabilitation, the neurological damage evaluated by the middle cerebral artery scale of Orgogozo, the initial functional damage evaluated by the functional score carried out within the scale of Functional Independence Measure (FIM), the existence of aphasia, of a depressive or hemineglect syndrome, presence of superficial or profound sensory disorders, incontinence at the start of rehabilitation and at one month after stroke, the existence of cognitive or psychiatric disorders. The non-parametric Mann-Whitney, the chi2, and the correlation test were used. The threshold of significance was .05. Based on 93 patients (47 women and 46 men, average age 64.8) 87.1% were walking at discharge, on average 3 months after stroke. The predictive factors or those linked to an absence of recovery were the presence of superficial sensory disorders, the initial neurological damage, the initial functional damage, the presence of a depressive syndrome, and urinary incontinence. We stress the significance of the sensorimotor and initial functional damage, and of incontinence in establishing a prognosis for recovery of walking ability, in order to decide the objectives and the rehabilitative treatment for each patient.
RESUMEN
OBJECTIVE: Our objective was to study the impact of pregnancy and delivery on vesicourethral disorders in patients with multiple sclerosis (MS). DESIGN AND SETTING: We performed a retrospective chart review of records of women diagnosed with MS who were referred to the clinic. PARTICIPANTS: A total of 102 women with MS (mean age of 44.7 +/- 11.4 years at the time of the study and mean age of 30.0 +/- 9.6 years at the onset of MS) participated in the study. The mean duration of disease was 15 +/- 10 years. The mean Expanded Disability Status Scale score was 5.4 +/- 1.8. MAIN OUTCOME MEASURES: For each patient, demographic data, disease characteristics, urological and obstetrical history and urodynamic data were collected. Urinary disorders were classified as irritative (urinary urgency and frequency) or as obstructive (hesitancy of micturition, reduced or interrupted urinary stream and sensation of incomplete bladder emptying). Urodynamic study consisted of cystometry with continuous recording of urethral sphincter electromyography in 77 (76%) cases. Intravesical and intraurethral pressures were recorded. Bladder dysfunctions were classified into neurogenic detrusor overactivity or detrusor underactivity. RESULTS: Pregnancies and deliveries did not influence symptoms. Moreover, the only statistical difference from a urodynamic point of view was a decrease in maximal urethral closure pressure. CONCLUSION: No interaction between pregnancy, delivery and urinary symptoms was found in this study. The effects of pregnancy and delivery seemed to be the same in women with MS and in healthy women, with a tendency towards a decrease in urethral pressure in women with MS.
