In recent years, great advances have been made in medical care for patients with GBS. However, the focus has been mainly on patient care in the acute phase and improving survival instead of long-term disability. The purpose of this study was to evaluate the efficacy of rehabilitation in people with GBS through a systematic review of randomized controlled trials. Area Covered: PRISMA guidelines were used to perform this systematic review. Six bibliographic databases were searched: PUBMED, WEB OF SCIENCE, PEDro, CINHAL, PSYCHINFO, and SCOPUS. Papers included in the systematic review should have a search design of a randomized controlled trial. The quality of the clinical trials included was evaluated according to Jadad score. Expert Opinion: After eliminating duplicates, 472 records got screened, three RCTs were included in the systematic review. Overall, the analysis of the three randomized controlled trials showed that various types of rehabilitation interventions are correlated to an improvement in the patient’s wellbeing. Finally, it is not possible to extrapolate definite conclusions on the effectiveness of rehabilitation treatment in patients with GBS. Therefore, high-quality future studies are needed to confirm these hypotheses. Received 16 December 2020 Accepted 10 February 2021 1. Introduction Guillain-Barrè syndrome (GBS) is an acute immune-mediated polyradiculoneuropathy caused by inflammation of the per­ ipheral nerves and nerve roots [1]. An immune response direc­ ted toward peripheral myelin induces the process that is often preceded by a viral or bacterial infection, surgery, immuniza­ tion, lymphoma, or toxins exposure [2]. GBS is a complex and heterogeneous syndrome induced by various types of lesions. The most common one is the acute inflammatory demyelinat­ ing polyradiculoneuropathy (AIDP), manifesting with primarily demyelinating features; acute axonal motor neuropathy (AMAN) is less common and is characterized by primarily axonal injury and pure motor involvement; acute motor sen­ sory axonal polyneuropathy (AMSAN) shows a similar patho­ genesis to AMAN with additional sensory involvement [3]. One of the main target regions of the autoimmune attack is the node of Ranvier; the nodal area, resulting in Nodopathy, and the internodal area may also be affected [4]. A worldwide epidemiological systemic review denotes that the overall incidence of GBS is around 1.1 to 1.8/100,000/year in adults, and it increases with age after 50 years, from 1.7/100,000/ year to 3.3/100,00/year [5]. In addition to this, there is a significantly higher risk in men of developing the disease [3]. GBS has an acute phase, which reaches the nadir within four weeks; because of the patchy nature of the inflammatory CONTACT Giovanni Galeoto, Rome, Italy. giovanni.galeoto@uniroma1.it © 2021 Informa UK Limited, trading as Taylor & Francis Group KEYWORDS Guillain-Barrè syndrome; proprioceptive Neuromuscular Facilitation; quality of life; rehabilitation; systematic review attack, demyelination of peripheral axons produces an acute symmetrical ascending paralysis, usually with progressive weakness, loss of deep tendon reflexes, and loss of sensation. These peripheral axonal lesions may be spontaneously more or less reversible. In 50% of cases, the cranial nerves are involved, with diplopia, facial, and bulbar weakness. Autonomic dysfunction, such as fluctuation in bloody pres­ sure, cardiac arrhythmias, and respiratory failure, often occur [6,7]. In percentage, 25% of people require ventilatory support due to respiratory tract involvement, and 5–10% of patients die in the acute phase [8]. After the progressive phase, the condition has a plateau of 1–2 weeks, and then a prolonged recovery phase begins [9]. Even if the relative mortality to Guillain-Barrè syndrome is low, and the outcomes are gener­ ally favorable, 20% of patients have a permanent severe dis­ ability, with deficits in ambulation, and ventilator assistance 12 months later, weakness, fatigue, pain, and sensory loss [10,11]. Furthermore, GBS’s impact on daily activities, work, social activities and health-related quality of life (HRQoL) is considerable two years after onset and presumably persists even after [12]. Many patients showed significant longer-term psychological sequelae, depression, and anxiety than a normative population due to persistent disability. In recent years, great advances have been made in medical care for patients with GBS. However, the focus has been mainly on Department of Human Neurosciences, Sapienza University of Rome, Viale Dell’ Università, 2 S. SULLI ET AL. Article highlights The aim of this systematic review was to evaluate the efficacy of rehabilitation in people with Guillain-Barrè syndrome. ● A total of 748 studies were retrieved from the search and 141 were evaluated after the first screening. After excluding 138 studies, 3 suitable randomized controlled trials were included. ● The analysis of the three randomized controlled trials showed that various types of rehabilitation interventions are correlated to an improvement in the patient’s well-being. ● Patients who survive the acute phase of Guillain-Barrè syndrome can develop different types of disabilities. Only one RCT evaluated differ­ ent outcomes and used a multidisciplinary approach for the treat­ ment of GBS. ● Our review highlighted that there is little quality evidence in GuillainBarrè rehabilitation. However, it is performed extensively in clinical practice, and for this reason, higher quality studies with high levels of evidence are required. ● patient care in the acute phase and improving survival instead of long-term disability, QoL improvement, and social participa­ tion. Indeed, long-term clinical care for patients with GBS remains fragmented [10]. Therefore, a multidisciplinary approach seems to be necessary because of the heterogeneity of symptoms. Even the most recent review [6] conducted on this topic showed a lack of standardized protocols for treating this disease. Therefore, this systematic review’s main purpose was to provide a summary of the primary studies available on the rehabilitation of Guillain-Barrè syndrome to support and justify the efficacy of this treatment, evaluating its effects. Also, our review serves as an update of the most recent evidence regarding this theme. 2. Body Health professionals of Sapienza University of Rome and ROMA – Rehabilitation & Outcome Measures Assessment Association performed the study. The research group has conducted many outcome measures in Italy [13–23]. or no therapies, were also included. All studies based on physical therapy to relieve discomfort and promote physical well-being were considered in individuals with GBS. No restric­ tions were applied to the type of interventions used. Papers concerning numerous rehabilitation aspects (fatigue, motor deficiencies, postural balance, muscle strength, gait training, cardiorespiratory response, sphincter control, endurance, and depression) were considered. Restrictions were applied to study designs. Only Randomized Controlled Trials were included. No language restrictions were applied in the research. There were no restrictions on the publication period. Inclusion criteria: The prerequisites of the studies necessary to be included in the systematic review were: (a) studies having a research design of randomized controlled trial; (b) studies published in English. Exclusion criteria: none. 2.3. Search methods All the studies in the published literature that include the key­ words (‘Guillain-Barrè syndrome’; ‘rehabilitation’) connected by the Boolean operator ‘AND’ were considered. Studies were selected for inclusion through individualized systematic searches of six electronic databases. Two reviewers selected all potential studies. The following electronic databases were sys­ tematically searched from May 2020 until July 2020: PUBMED, SCOPUS, WEB OF SCIENCE, CYNAL, PSYCINFO, PEDRO. 2.4. Selection of studies Titles, abstracts, and keywords selected through the databases were screened independently by two physiotherapists. After the first screening, the primary reviewer identified the relevant studies and rated them according to the inclusion criteria. Then, a second reviewer cross-checked the studies. After the second screening, studies that did not meet the inclusion criteria were systematically excluded, and others that seemed relevant were identified. A final list of studies eligible for inclusion was made, and any disagreements were resolved by the third reviewer or by consensus. Studies that met the criteria were then subjected to a full text review to select studies to decide whether to include them in the review. 2.1. Protocol and registration The protocol was recorded on the Prospero website, the inter­ national prospective register of systematic reviews, available at https://www.crd.york.ac.uk/prospero/. This review was then performed according to the 27-item PRISMA Statement for Reporting Systematic Reviews based on MECIR. 2.2. Eligibility criteria for considering studies for this review: types of studies, participants, and intervention Studies were limited to people with Guillain-Barrè syndrome, independently of clinical course or length of time since diag­ nosis. Studies with mixed diagnosis samples were included if a subgroup of participants could be identified and for which separate data were available. Studies that include comparing physical therapy and conventional therapies, other therapies, 2.5. Data extraction and risk of bias The data mining approach was chosen based on Cochrane methods. Two reviewers independently extracted patient demographics and descriptive information, and each study was equipped with keywords for generic issues such as lan­ guage, country, focus, population, and so on. Regarding the analysis and discussion of the results, the following data were extracted for the study and design: author and study design. For study participants: number, age, gender, treatment groups. For the intervention protocol: type of exer­ cise, intervention time, intensity; conclusions of the study. The risk of bias was assessed using one of the available tools appropriate for the studies to be evaluated. The Jadad scale was applied to each included study, a full table of risk of bias is applied in the published review, including evidence to support EXPERT REVIEW OF NEUROTHERAPEUTICS 3 each judgment. The authors did not apply the Jadad scale to non-randomized study designs but instead assessed the evi­ dence’s validity as part of the interpretation of any results. studies were excluded. After excluding 138 studies for the inappropriate design of the research, three studies [10,24,25] were included in the quantitative synthesis figure 1. 2.6. Strategy for data synthesis 3.2. Study characteristics: types of design and types of participants A narrative summary of the results of the included studies was provided, structured according to the type of intervention, the characteristics of the target population, the type of outcome, and the intervention’s object. A quantitative synthesis of the benefits of rehabilitation in people with GBS was discussed. 2.7. Data items in the included studies The following items were analyzed for each article included in the review [1]: participants’ details (age, type of GBS) [2]; intervention (control and experimental group) [5]; rates of treatment [3]; outcomes measurement tools [6]; follow-up [7]; conclusions [8]; Jadad score. 3. Conclusion 3.1. Search result A total of 748 studies were identified. No article has been added through other resources. Two hundred seventy-six duplicate studies were excluded, and the remaining 472 were screened. After reading the titles and abstracts, 330 At the end of the screening and selection process, three studies have been identified, all of which are randomized-controlled trials, compatible with this systematic review’s objective. The sample size in three studies [10,24,25] ranged from 30 [24] to 79 [10]; only in one study [25] was the sample size not calculated, and 22 participants were recruited. In two studies [10,25], the majority of participants were men; in the remain­ ing study [24], gender has not been reported. Studies use different ways to report the ages of participants. Therefore, table 1 contains this information. From the summary of the records, different treatment modalities used for the experimental group were found. The interventions include PNF techniques associated with dia­ phragmatic breathing exercises [24], exercises on strength and resistance at high intensity, gait training [10], pranayama sessions added to regular rehabilitation care [25]. The organi­ zations of the intervention sessions are contained in Table 1. The control group received usual care or regular rehabilitation program performed in part or completely.

Furthermore, follow-up was done after 12 months in [10], after 15 sessions in [25], and after intervention on seventh day [24]. 3.3. Risk of bias within study Jadad Score is used for the qualitative analysis of the trials included in the systematic review. Based on this assessment, it was found that two studies [10,25] got a score of three, revealing high-level quality. The remaining study [24] pre­ sented a score that underlines a low qualitative level. For all data, see table 2. 3.4. Synthesis of evidence According to our research, three randomized-controlled trials were suitable for quantitative analysis. However, it was impos­ sible to perform the metanalysis due to the diversity of out­ comes and follow-up between records. The study of Khan F. et al. 2011 [10] aimed to evaluate the effectiveness of a highintensity rehabilitation program compared to a low-intensity rehabilitation program after 12 months in a population of 79 patients with chronic Guillain-Barrè syndrome. After follow-up, ten patients were lost, and the remaining 69 (treatment n = 35, control n = 34) were analyzed; significant improvements were found in FIM total score (p < 0.003) in the treatment group, compared with the control group. Moreover, significant differ­ ences between both groups have been found in each FIM motor subscales: mobility/transfers (p = 0.002), locomotion (p = 0.005), and sphincter control (p = 0.003). No statistically significant differences were observed between both groups in EXPERT REVIEW OF NEUROTHERAPEUTICS secondary outcome measures, except for the PIPP “relationship’ subscale (p = 0.011). In conclusion, a 12-week high-intensity rehabilitation program consisting of 1-hour sessions 2–3 times per week of physiotherapy for strengthening, endurance, and gait training, in addition to occupational and psychological therapy, appears to help reduce motor disability in patients with chronic GBS. The study of Ragupathy S. et al. 2013 [25] wanted to inves­ tigate pranayama and meditation’s effect on regular rehabilita­ tion in 22 patients with GBS. In both groups (study and control), patients received rehabilitation care; among the interventions used, physiotherapy included active assisted range of motion, passive range of motion, stretching of tight muscles, strength­ ening exercises, breathing exercises, and gait training. In addi­ tion to this, the experimental group received 15 sessions of yoga (1 hour a day) that included quick relaxation technique, pranayama, and guided meditation (Mind Sound Resonance TechniqueMSRT). The outcome measures of 20 patients, with two dropouts, reported significant differences between the groups in the quality of sleep, measured by the PSQI (p = 0.048). It was seen that there was a reduction of anxiety and depression (HADS), pain scores (NPRS), and an improve­ ment in functional status (Barthel.index) in both groups without statistical differences. The authors argued that the use of yogic relaxation, pranayama, and meditation techniques, added to regular rehabilitation, appears to help improve sleep quality. In the Randomized Controlled Trial of Vidhyadhari B.S. L. et al. 2015 [24], the purpose was to assess the propriocep­ tive neuromuscular facilitation techniques’ efficacy on pul­ monary function (FEV1/FVC) and diaphragm muscle activity in a population of 30 patients with Guillain-Barrè syndrome. The assessment of these parameters was done using EMG biofeedback machine and portable electronic spirometer. The experimental group (15 participants) performed PNF exercises and techniques, such as repeated stabilization and rhythmic contractions, in addition to diaphragmatic breathing exercises, for 15 min, three repetitions, three sets, and seven days in one week. The control group (15 participants) performed exclu­ sively diaphragmatic breathing exercises with the same volume, intensity, and frequency. In extrapolating the results, the authors did not provide statistical tables. However, they declared that significant differences in parameters were found in both groups before and after the test (p < 0.05), but compared to the control group, greater changes occurred in the group of study (p < 0.05). Based on the information reported, PNF techniques facilitate diaphragmatic activity and improve pulmonary function in patients with GBS. Nevertheless, through our research, this is the only study investigating these symptoms using this specific technique, and therefore we believe that similar new studies are required. 5 3.5. Study limits The limits of this study concern the small number of RCTs in the literature. The heterogeneity of the phase of illness, the small size of the patients in the trials, and the lack of double blinding is closely related to the nature of the studies consid­ ered. Another underlining limit is the use of only six databases. It is important to note that studies included in this review do not account for the clinical variants of GBS. Finally, the studies’ partial information found that the different timing of followup and their different outcome measures did not permit us to carry out a qualitative analysis with metanalysis. 4. Expert opinion Guillain-Barrè syndrome is a rare autoimmune disease that involves peripheral nerves and is potentially life-threatening [26]. Some of the patients who survive the acute phase pre­ sent motor and sensitive sequelae, deficits in ambulation, weakness and pain, which negatively impact daily life activities [27]. Therefore, a long-term rehabilitation program is needed to manage the patient’s complications [28], but currently, there are no defined guidelines on this type of intervention reported in the literature. The most recent systematic review investigating this topic was done by Arsenault et al. in 2016 [6] to evaluate the influence of exercise on patients with GBS; however, from the analysis of the included studies, having different research designs, the authors could not draw defini­ tive and standardized conclusions. The analysis of the three randomized controlled trials showed that, in general, various types of rehabilitation interventions are correlated to an improvement in the patient’s well-being. In particular, the assessment of physical outcomes was pursued by the studies of Khan F. et al. 2011 [10] and Vidhyadhari B.S.L. et al. 2015 [24], although the authors focused on evaluations of different parameters. Furthermore, the difference in quality between the two studies, highlighted by the Jadad scale, prompts us to consider the rehabilitation program proposed by Khan F. et al. 2011 [10] with greater authority. Therefore, to reduce symptoms and to improve activity and participation, it seems to be useful to increase the intensity within a rehabilitation program through a greater frequency of therapy sessions (one hour of therapy three times a week), more types of interventions (occupational, social, psychological, speech and physiotherapy therapy) and a greater intensity of physical exercises (therapy for strengthening, endurance, and gait training). Moreover, Khan F. et al. 2011 [10] and Vidhyadhari B.S.L. et al. 2015 [24] also considered bio-psycho-social out­ comes. Although they use different measures and interven­ tions, both studies did not report statistically significant Table 2. Jadad score.

The different results of the studies do not allow us to standardize an outlined rehabilitation pro­ tocol since both the outcomes and the proposed interventions are not comparable. Furthermore, these studies do not con­ sider the different clinical features of Guillain-Barré syndrome and rehabilitation intervention is not diversified even though patients may be at different stages of the disease. Because this condition causes several types of disability, a multidisciplinary approach seems to be necessary, as sup­ ported by scientific evidence [1]. In fact, Khan F. et al. 2011 [10] is the only randomized controlled trial that evaluated different outcomes and used a multidisciplinary approach, and this demonstrates the effectiveness of its intervention. 5. Conclusion Our review highlighted that there is little quality evidence in Guillain-Barrè rehabilitation. However, it is performed exten­ sively in clinical practice, and for this reason, prospective multicenter RCtrials based on patients’ clinical, biological, and electrophysiological data in addition to myelinating fiber types and lesion levels are needed. The main problem in carrying out an effective rehabilitation protocol for patients with GBS is related to the heterogeneity of outcome measures and interventions used. In conclusion, to facilitate comparison between studies, standardized, specific, sensitive, and valid outcome measures should be established in the future.
