Muscle strength recovery in treated Guillain-Barré syndrome: a prospective study for the first 18 months after onset

Supervised, individualised exercise reduces fatigue and improves strength and quality of life more than unsupervised home exercise in people with chronic Guillain-Barré syndrome: a randomised trial

QUESTION

In people in the chronic phase of Guillain-Barré syndrome (GBS), how much more does a supervised, individualised exercise program improve functional independence with activities of daily living than a home-based exercise program? How do the two exercise programs compare regarding their effects on muscle strength, fatigue, pain and quality of life?

DESIGN

Randomised controlled trial with concealed allocation, intention-to-treat analysis and blinding of outcome assessors.

PARTICIPANTS

Sixteen adults with stable residual disability ≥ 6 months after the onset of GBS.

INTERVENTION

Participants in the experimental group were allocated to 60-minute sessions of physiotherapist-supervised strengthening, endurance and breathing exercises, gait training and pain management, two to three sessions/week for 12 weeks. The control group was prescribed a home program of 30-minute sessions of maintenance exercises and education in self-management, two to three sessions/week for 12 weeks.

OUTCOME MEASURES

Functional independence in activities of daily living on the 100-point Barthel Index (primary outcome), muscle strength on the 60-point Medical Research Council scale, fatigue on the 0-to-63 Fatigue Severity Scale, a visual analogue scale of pain severity, and quality of life, measured at baseline and months 6 and 12.

RESULTS

At month 6, the median between-group difference was 5 (95% CI 0 to 20) for functional independence, 8 (95% CI 4 to 18) for strength, -13 (95% CI -28 to -1) for fatigue, and 12 (95% CI 3 to 13) for the environment domain of quality of life. Estimated effects at month 12 had a similar magnitude, but most of the CIs had greater uncertainty.

CONCLUSION

Supervised, individualised exercise reduced fatigue and improved strength and quality of life more than unsupervised home exercise in people with chronic Guillain-Barré syndrome.

Berg balance scale as a tool for choosing the walking aid for patients with Guillain-Barré syndrome or polyneuropathy

Berg balance scale (BBS) is a widely used outcome measure in rehabilitation. We wanted to check if it can discriminate among levels of use of walking aid in patients with Guillain-Barré syndrome or polyneuropathy. A retrospective audit of 109 such patients (aged 16-85 years) who had completed inpatient rehabilitation in the period 2012-2017 was conducted. Receiver operating characteristic curve analysis was used to estimate the thresholds that optimise the prediction of the patient's walking aid. Statistically, significant threshold BBS score was estimated for the ability to walk without walking aid (≥49 points, yielding 88% sensitivity, 68% specificity and 83% classification accuracy) and the necessity to walk with a walker (≤37 points, yielding 62% sensitivity, 83% specificity and 78% classification accuracy). BBS score thresholds can therefore help clinicians choose the appropriate walking aid for patients with Guillain-Barré syndrome or polyneuropathy undergoing rehabilitation.

Influence of Exercise on Patients with Guillain-Barré Syndrome: A Systematic Review

Purpose: To evaluate the effects of exercise interventions on improving physical outcomes in patients with Guillain-Barré syndrome (GBS). Methods: The PubMed database was searched for articles published up to and including February 2015. Randomized controlled trials (RCTs), case reports, and quasi-experimental and single-subject designs published in English-language, peer-reviewed journals that assessed the impact of physical exercise on patients with GBS were included; study quality was assessed using Sackett's rules of evidence. Data are presented qualitatively and quantitatively using numerical values and percentages. Results: Seven articles were included in the systematic review. One RCT showed that high-intensity relative to lower intensity exercise significantly reduced disability in patients with GBS, as measured with the FIM (p<0.005, r=0.71). Overall, various types of exercise programmes improve physical outcomes such as functional mobility, cardiopulmonary function, isokinetic muscle strength, and work rate and reduce fatigue in patients with GBS. Conclusion: Because of insufficient high-quality literature, making confident conclusions about the effects of exercise interventions on physical outcomes in patients with GBS is not possible. Future research should consider using higher quality study designs to confirm the results outlined in this article.

A novel virtual motor rehabilitation system for Guillain-Barré syndrome. Two single case studies

INTRODUCTION

This article is part of the Focus Theme of Methods of Information in Medicine on "New Methodologies for Patients Rehabilitation".

OBJECTIVES

For Guillain-Barré patients, motor rehabilitation programs are helpful at the onset to prevent the complications of paralysis and in cases of persistent motor impairment. Traditional motor rehabilitation programs may be tedious and monotonous, resulting in low adherence to the treatments. A Virtual Motor Rehabilitation system has been tested in Guillain-Barré patients to increase patient adherence and to improve clinical results.

METHODS

Two people with Guillain-Barré performed 20 rehabilitation sessions. We tested a novel system based on Motor Virtual Rehabilitation in three periods of time (baseline evaluation, final evaluation, and follow-up. In the training program, the participants carried out a specific treatment using the Active Balance Rehabilitation system (ABAR). The system is composed of customizable virtual games to perform static and dynamic balance rehabilitation.

RESULTS

Significant improvements in clinical results were obtained by both participants, with significant results in the static balance clinical test of the Anterior Reach test in the standing position and unipedal stance time. Other significant results were found in dynamic balance clinical tests in the Berg Balance Scale test and the 30-second Sit-to-Stand test. With regard to acceptance of the system, both patients enjoyed the experience, and both patients thought that this system was helpful for their rehabilitation.

CONCLUSIONS

The results show that Virtual Motor Rehabilitation for Guillain-Barré patients provides clinical improvements in an entertaining way.

Functional recovery of untreated human immunodeficiency virus-associated Guillain-Barré syndrome: a case report

HIV-associated Guillain-Barré syndrome is a well-documented phenomenon, typically occurring at seroconversion. GBS may result in functional impairment treated with a combination of medications, plasmapheresis, and rehabilitation. The quantified functional recovery of HIV-associated GBS with or without HIV treatment is not well described. Utilizing serial FIM scoring, we describe a patient's recovery from HIV-associated GBS after treatment with IVIg and acute inpatient rehabilitation without HIV treatment.

Use of the International Classification of Functioning, Disability and Health to identify preliminary comprehensive and brief core sets for Guillain Barre syndrome

PURPOSE

To identify the preliminary comprehensive and brief core sets for Guillain Barre syndrome (GBS), in a Delphi process using the International Classification of Functioning, Disability and Health (ICF).

METHOD

Focus groups and a consensus process were used to identify ICF core sets for GBS. This included: preliminary ICF studies; empirical patient data collection for 77 GBS participants; review of the evidence base and treatment in GBS literature followed by a Delphi exercise with 23 physicians and allied health professionals in Melbourne, Australia.

RESULTS

The expert consensus selected 99 second level ICF categories (in three rounds) which identify health domains relevant to GBS for multidisciplinary assessment. These domains were consistent with current practice and existing GBS literature. The comprehensive core set includes: 27 (23%) categories from the component 'body function', 7 (12%) categories from 'body structures', 43 (36%) from 'activities and participation' and 22 (29%) from the component 'environmental' factors. The brief set comprised 20 categories, 20% of categories in the comprehensive core set.

CONCLUSION

The core set categories for GBS-related health need to be addressed in multidisciplinary care programs. Future clinical 'rating' of this set may facilitate scale development using the ICF in GBS. Further research is needed to confirm the generalisability of this set in clinical settings.

Multidisciplinary care for Guillain-Barré syndrome

BACKGROUND

Guillain-Barré syndrome is a significant cause of new long-term disability, which is thought to be amenable to multidisciplinary care, but the evidence base for its effectiveness is unclear.

OBJECTIVES

To assess the effectiveness of multidisciplinary care in adults with Guillain-Barré syndrome, especially the types of approaches that are effective (settings, intensity) and the outcomes that are affected.

SEARCH STRATEGY

We searched the Cochrane Neuromuscular Disease Group Specialized Register (20 May 2010), The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 2), MEDLINE (1966 to May 2010), EMBASE (1980 to May 2010), CINAHL (1982 to May 2010), AMED (1985 to May 2010), PEDro (1982 to May 2010) and LILACS (1982 to May 2010). We checked the bibliographies of papers identified and contacted their authors and known experts in the field seeking published and unpublished trials.

SELECTION CRITERIA

Randomised and controlled clinical trials that compared multidisciplinary care in Guillain-Barré syndrome with either routinely available local services or lower levels of intervention, or studies that compared multidisciplinary care in different settings or at different levels of intensity.Studies of 'other designs' (such as observational studies) were included only in the Discussion since such studies could only be of limited contribution to the best evidence synthesis.

DATA COLLECTION AND ANALYSIS

We performed a 'best evidence' synthesis based on methodological quality.

MAIN RESULTS

No randomised controlled trials or controlled clinical trials were identified. We summarised the results of three observational studies in the Discussion section of this review.

AUTHORS' CONCLUSIONS

In the absence of randomised controlled trials or controlled clinical trials, the 'best' evidence to date comes from three 'very low quality' observational studies. These provide some support for improved disability in the short term (less than 6 months) with high intensity inpatient multidisciplinary rehabilitation; and for improved quality of life, as measured by a reduction in handicap (participation). These conclusions are tentative and the gap in current research should not be interpreted as proof that multidisciplinary care is ineffective. Further research is needed into appropriate study designs; outcome measurement; caregiver needs; and the evaluation of optimal settings, type, intensity or frequency and cost-effectiveness of multidisciplinary care in the Guillain-Barré syndrome population.
