Nutritional status in patients with advanced-stage multiple sclerosis.

INTRODUCTION: Motor and swallowing dysfunctions in multiple sclerosis (MS) unbalance calorie intake and energy expenditure, modifying nutritional status. Only one study has described nutritional status in MS patients at early disease stages (median Expanded Disability Status Scale [EDSS] = 3), but this has never been assessed in the most severe cases. The goal of the present study was to describe nutritional status in advanced-stage MS. METHODS: The study was a non-interventional retrospective analysis of a prospective registry. We reviewed medical files of consecutive MS patients admitted for annual follow-up in a physical and rehabilitation medicine unit between May 2016 and October 2018. Malnutrition for frail people, according to the French Health Authority (Haute Autorité de Santé [HAS]) definition, was our composite primary outcome criterion: body mass index (BMI) <21 kg/m2 and/or albumin<35 g/L. First, we performed a descriptive analysis of the nutritional status. Second, we studied the association between malnutrition and MS characteristics in univariate and multivariate analyses. RESULTS: A total of 163 patients with median EDSS = 8 [7; 8.5] were included. Ninety-three patients (57%) met HAS malnutrition criteria (36% with albumin <35 g/L, 31% with BMI <21 kg/m2 and 10% with both). Malnutrition was associated in univariate analysis with MS severity (EDSS ≥8.5, p = 0.0003), primary progressive type of MS (p = 0.01) and swallowing disorders (p = 0.002). Multivariate analysis showed that low disability status (EDSS <7) was the only independent (protective) factor associated with malnutrition (OR = 0.2, p = 0.03). CONCLUSIONS: Malnutrition is frequent in advanced stages of MS and is probably a key point for therapeutics, which has never been demonstrated previously. A standardized evaluation should be developed to improve nutritional therapeutic strategies in this population.

Effect of power-assistance on upper limb biomechanical and physiological variables during a 6-minute, manual wheelchair propulsion test: a randomised, cross-over study.

PURPOSE: Use of a power-assistance wheelchair could reduce the risk of musculoskeletal disorders (MSDs), however, a comprehensive biomechanical evaluation of these systems has not been carried out. This study aimed to evaluate and compare biomechanical UL propulsion variables, and physiological exercise-related variables during the use of a wheelchair with rear drive power assist device (RD-PAD) and a standard manual wheelchair (MW). MATERIALS AND METHODS: Twenty-two adults with spinal cord injury were recruited. RD-PAD (SmartDrive system) was fitted to their own MW. An instrumented wheel was used to measure handrim forces, and gas exchange and heart rate were monitored. Participants performed repeated out and back runs for 6 min on a straight outdoor course. RESULTS: Distance covered was significantly greater with the RD-PAD (538 ± 104 m versus 470 ± 124 m). Peak mechanical effort during the propulsion phase was significantly lower with the RD-PAD (p < 0.001). Heart rate, metabolic equivalent of task (MET), tidal volume, minute volume, oxygen consumption, and peak oxygen consumption were all significantly lower with the RD-PAD (p < 0.001). CONCLUSIONS: The results showed that use of RD-PAD increased the distance covered by MW users and reduced the energy costs of propulsion. The biomechanical results indirectly suggest that RD-PAD may reduce the risk of MSD.Implications for RehabilitationUsing the SmartDrive system as propulsion assistance increases the travel autonomy.The SmartDrive system reduces the biomechanical constraints propelling the wheelchair on a slope and low slope.SmartDrive the system reduces the physiological solicitation related to the propulsion of wheelchair.

Spinal cord ischemia in Scheuermann disease: A report of three cases.

BACKGROUND: Neurological complications in Scheuermann's disease are rare but serious. CASE REPORTS: We report three cases of severe neurological deficit due to medullar ischemia attributable to the compression of a radiculomedullar artery by thoracic (two cases) and lumbar (one case) disc herniations associated with Scheuermann's disease. They were not treated surgically because of the absence of direct spinal cord compression or definitive spinal cord ischemia. Those young patients still have severe neurological damage. An earlier management could have prevented them. CONCLUSION: When doubting about any compressive sign, MRI should be performed with diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) sequences in emergency.

Recommendations and settings of word prediction software by health-related professionals for patients with spinal cord injury: a prospective observational study.

BACKGROUND: For people with cervical spinal cord injury (SCI), access to computers can be difficult, thus several devices have been developed to facilitate their use. However, text input speed remains very slow compared to users who do not have a disability, even with these devices. Several methods have been developed to increase text input speed, such as word prediction software (WPS). Health-related professionals (HRP) often recommend this type of software to people with cervical SCI. WPS can be customized using different settings. It is likely that the settings used will influence the effectiveness of the software on text input speed. However, there is currently a lack of literature regarding professional practices for the setting of WPS as well as the impact for users. AIM: To analyze word prediction software settings used by HRP for people with cervical SCI. DESIGN: Prospective observational study. SETTING: Garches, France; health-related professionals who recommend Word Prediction Software. METHODS: A questionnaire was submitted to HRP who advise tetraplegic people regarding the use of communication devices. RESULTS: A total of 93 professionals responded to the survey. The most frequently recommended software was Skippy, a commercially available software. HRP rated the importance of the possibility to customise the settings as high. Moreover, they rated some settings as more important than others (P<0.001). However, except for the number of words displayed, each setting was configured by less than 50% of HRP. The results showed that there was a difference between the perception of the importance of some settings and data in the literature regarding the optimization of settings. Moreover, although some parameters were considered as very important, they were rarely specifically configured. Confidence in default settings and lack of information regarding optimal settings seem to be the main reasons for this discordance. This could also explain the disparate results of studies which evaluated the impact of WPS on text input speed in people with cervical SCI. CONCLUSION: The results showed that there was a difference between the perception of the importance of some settings and data in the literature regarding the optimization of settings. Moreover, although some parameters were considered as very important, they were rarely specifically configured. Confidence in default settings and lack of information regarding optimal settings seem to be the main reasons for this discordance. This could also explain the disparate results of studies which evaluated the impact of WPS on text input speed in people with cervical SCI. CLINICAL REHABILITATION IMPACT: Professionals tend to have confidence in default settings, despite the fact they are not always appropriate for users. It thus seems essential to develop information networks and training to disseminate the results of studies and in consequence possibly improve communication for people with cervical SCI who use such devices.

Occurrence of adverse events in long-term intrathecal baclofen infusion: a 1-year follow-up study of 158 adults.

OBJECTIVE: To assess the frequency and types of adverse events (AEs) related to intrathecal baclofen (ITB) therapy in adults, and associated risk factors. DESIGN: A prospective, observational cohort study of adults followed up from January 1 to December 31, 2010. SETTING: A neurologic rehabilitation department in a university hospital. PARTICIPANTS: All consecutive adult subjects (N=158) receiving ITB via a pump, either implanted or followed up during the study period. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Frequency and type of AEs. RESULTS: In 2010, 158 subjects were followed up for ITB therapy, of whom 128 were implanted before 2010 (nonsurgical subjects), and 30 underwent implantation in 2010 (surgical subjects). Of these 30 subjects, 20 were "newly implanted" and 10 were "replacements." The most frequent pathologic disorders were spinal cord injury (42%) and multiple sclerosis (28%). Twenty-eight subjects (18%) experienced a total of 38 AEs. The rate of AEs was .023 per month of ITB treatment. AEs were related to the surgical procedure in 53% of cases, to the device in 29% (predominantly catheter dysfunctions), and to adverse effects of baclofen in 18%. AEs related to the surgical incision (scar complications and collections) were more frequent in replacement than newly implanted subjects (P=.009). No significant association between occurrence of an AE and subject characteristics (age, gait capacity, spinal vs cerebral spasticity, duration of ITB therapy follow-up) was found. Nearly half of the AEs were serious, extending admission time by a mean of 16 days. No AE induced long-term morbidity or death. CONCLUSIONS: The AE rate was relatively low in this cohort. This has to be balanced against the clinical, functional, and quality-of-life improvements, which are expected from ITB therapy.

Rehabilitation of balance after stroke with multisensorial training: a single-blind randomized controlled study.

OBJECTIVE: To compare 2 rehabilitation strategies to improve balance after stroke: (1) a multisensorial approach based on higher intensity of balance tasks and exercise during visual deprivation and (2) a conventional neurodevelopmentaltheory-based treatment (NDT) that used a general approach for sensorimotor rehabilitation. METHODS: This prospective, multicenter, randomized, parallel-group study measured outcomes with blinded assessors. Sixty-eight patients able to walk without human assistance were entered from 3 to 15 months (mean, 7 months) after a first hemispheric stroke. They received 20 sessions in 4 weeks of NDT or multisensorial rehabilitation. On day 0, day 30, and day 90, assessment included the Berg Balance Scale (BBS), posturography, gait (velocity, double stance phase, climbing 10 steps, amount of walking per day), the Functional Independence Measure, and the Nottingham Health Profile. RESULTS: All subjects improved significantly in balance and walking parameters. Regarding the main dependent variable (BBS on day 30), no difference between groups was found. Analysis of secondary outcomes suggested small differences in favor of the experimental group, but the differences are not likely to be clinically relevant. CONCLUSION: No evidence was found for the superiority of a multisensorial rehabilitation program in ambulatory patients with impairments beyond the time of inpatient therapy. Additional studies are recommended.

Pruritus after intrathecal baclofen withdrawal: A retrospective study.

OBJECTIVES: To determine the frequency of pruritus after intrathecal baclofen (ITB) withdrawal and to study the pathophysiology of this symptom. DESIGN: Retrospective cohort study. SETTING: Rehabilitation department of a general hospital. PARTICIPANTS: Patients (N=102) implanted with an ITB pump who had been followed up since 1988. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Incidence of pruritus after withdrawal. We studied the relation between pruritus and daily dose, concentration and mode of infusion of baclofen, and cause of the central nervous system lesion inducing spasticity. RESULTS: Pruritus was observed in 10 of 23 cases of ITB withdrawal. It never occurred during the first 3 months after pump implantation. It seems likely that the segmental spinal action of baclofen is responsible for pruritus. There was no statistically significant difference between patients with ITB deprivation who did and did not experience pruritus in their daily infused dosage or in concentration and mode of infusion. Surprisingly, no pruritus was observed in patients with multiple sclerosis. CONCLUSIONS: Pruritus is a frequent symptom after ITB withdrawal. Its occurrence is probably subsequent to chronic blocking of the liberation of substance P by baclofen at the spinal level. This symptom is a good clinical predictor of baclofen withdrawal, in contrast to an isolated increase of spasticity that may be due to drug tolerance or irritant factors. Pruritus requires investigation of a possible dysfunction of the infusion system.
