Comparison of the influence of different rehabilitation programmes on clinical, spirometric and spiroergometric parameters in patients with multiple sclerosis

Benefits of self-paced concurrent training on lung function, cardiopulmonary fitness and fatigue perception in patients with multiple sclerosis

Aim: Studying the effects of self-paced concurrent high-intensity interval training and resistance training (HIIT-RT) on respiratory function, cardiopulmonary fitness and fatigue perception in patients with multiple sclerosis (PwMS).Methods: Twenty-three PwMS were randomized into a 12-week training group (three times per week) (TG, n = 11) or a control group (CG, n = 12). Lung function (spirometry), aerobic capacity (graded cardiopulmonary-exercise-testing) and perceived fatigue (Fatigue Severity Scale (FSS)) were evaluated pre- and post-intervention.Results: The forced vital capacity (p = 0.036, Hedges'g (g) = 0.93), forced expiratory time (p = 0.045, g = 0.88), peak expiratory flow (p = 0.043, g = 0.89) increased in TG compared with CG. The TG showed an increase in peak aerobic power (p = 0.004, g = 1.34) and peak oxygen uptake (p < 0.001, g = 2.58) compared with CG. There was a decrease in ventilatory equivalent for carbon dioxide (p = 0.02, g = 1.02) and FSS scores (p < 0.001, g = 1.72) in TG comparatively with CG.Conclusion: 12-week self-paced HIIT-RT enhanced lung function as well as aerobic fitness, and alleviated fatigue perception in PwMS.

Quality of reporting health behaviors for multiple sclerosis (QuoRH-MS): A scoping review to inform intervention planning and improve consistency of reporting

BACKGROUND

Multiple sclerosis (MS) is a neurological condition that necessitates a multidisciplinary approach to aid those living with MS in managing their disease. Health behavior, or lifestyle modification, is an emerging approach to MS self-management. MS researchers utilize measurement tools to ensure that interventions are best suited to the outcomes, thereby potentially influencing practice. The aim of this study was to investigate which tools are being used for health behavior management studies in people living with MS and develop an aid for tool selection.

METHODS

A scoping review guided by the PRISMA-Sc checklist and the JBI manual for evidence synthesis was employed with a systematic search strategy executed across four scientific databases: Medline, PubMed, CINAHL, and Cochrane Libraries. The types of assessment tools used were extracted from the included studies. Each tool was categorized into the health behavior intervention discipline (nutrition, exercise, and psychology) and then subcategorized by the tool's purpose. The frequency of use was determined for each tool. Reporting of validation of the assessment tools were collated to inform a tool selection checklist.

RESULTS

The review identified a total of 248 tools (12 nutrition, 55 exercise, and 119 psychology unique reports) from 166 studies. Seventy-seven multidimensional tools were identified including measures of quality of life, fatigue, and functional scales. Only 88 studies (53%) referred to the validity of the tools. The most commonly reported tools were the dietary habits questionnaire (n = 4, nutrition), 6-minute walk test (n = 17, exercise), Symbol Digits and Modalities Test, and Hospital Anxiety and Depression Scale (n = 15 each, psychology) with the Expanded Disability Status Scale reported 43 times.

CONCLUSION

Evidence from interventions may inform practice for health professionals. This review provides insights into the range of tools reported across health behavior intervention studies for MS and offers a guide toward more consistent reporting of study methods.

People with newly diagnosed multiple sclerosis benefit from a complex preventative intervention-a single group prospective study with follow up

Background

Newly diagnosed people with multiple sclerosis frequently report fatigue, pain, depression and anxiety. Preventative programmes may be beneficial, but there is limited evidence of their effectiveness, especially long-term follow-up.

Methods

The programme consisted of 6-month face to face intervention (an introductory workshop, psychology-led group sessions and individual physical therapy) followed by 6-month self-guided therapy. Outcome measures were taken at baseline, 6 and 12 months. Primary outcomes measures were self-report questionnaires for fatigue, satisfaction with life and disease acceptance. Secondary outcomes were spirometry, spiroergometric parameters and neuroactive steroid levels.

Results

From 22 participants enrolled, 17 completed the first 6 months and 13 the follow-up. Fatigue measured on the Fatigue scale for motor and cognitive functions decreased significantly at 6 months (p = 0.035) and at follow-up (p = 0.007). The Modified Fatigue Impact Scale (p = 0.035) and Satisfaction With Life Scale (p = 0.007) significantly increased at follow-up. Spirometry, spiroergometric parameters, steroid hormones and neuroactive steroids levels did not change significantly.

Conclusion

This programme reduces fatigue and improves satisfaction with life in this patient group with improvements sustained at 12 months. People who participated more frequently showed greater benefit.

Clinical rehabilitation impact

The paper describes the effects of a complex preventative intervention for people with newly diagnosed Multiple Sclerosis. The study found that this programme reduces fatigue and improves satisfaction with life with long-term benefit (at 12-month follow up). The individuals who participated less frequently experienced fewer benefits.

Comparative effectiveness of four exercise interventions followed by two years of exercise maintenance in multiple sclerosis: A randomized control trial

OBJECTIVE

To determine the effects of Exergaming on quality of life (QoL), motor, and clinical symptoms in Multiple Sclerosis. We compared the effects of exergaming (EXE), balance (BAL), cycling (CYC), proprioceptive neuromuscular facilitation (PNF), and a standard care wait-listed control group (CON) on clinical and motor symptoms and quality of life (QoL) in people with MS (PwMS) and determined the effects of subsequent maintenance programs for 2 years in a hospital setting.

DESIGN

A randomized clinical trial, using before-after test design.

SETTINGS

University Hospital Setting PARTICIPANTS: Of 82 multiple sclerosis outpatients, 70 were randomized, and 68 completed the study.

INTERVENTIONS

The initial high-intensity and -frequency interventions consisted of 25, 1-h sessions over 5 weeks. After the 5-wk-long initial intervention, the 2-year-long maintenance programs followed, consisting of 3 sessions per week, each for 1h.

MAIN OUTCOME MEASURES

The primary outcome: Multiple Sclerosis Impact Scale (MSIS-29).

SECONDARY OUTCOMES

Measures five aspects of health-related QoL (EQ-5D index), Beck Depression Inventory, six-minute walk test (6MWT), Berg Balance Scale (BBS), Tinetti Assessment Tool (TAT) and static balance (center of pressure, COP).

RESULTS

MSIS-29 improved most in EXE (11 points), BAL (6), and CYC (6, all p<0.05). QoL improved most in EXE (3 points) and CYC and BAL (2, all p<0.05). TAT and BBS improved significantly (p<0.05) but similarly (p>0.05) in EXE, BAL, and CYC. 6MWT improved most in EXE (57m), BAL (32m), and CYC (19m all p<0.001). Standing sway did not change. Maintenance programs further increased the initial exercise-induced gains, robustly in EXE.

CONCLUSION

25 sessions of EXE, BAL, CYC, and PNF, in this order, improved clinical and motor symptoms and QoL and subsequent, 2-y-long thrice weekly maintenance programs further slowed symptom-worsening and improved QoL. EXE was the most and PNF was the least effective to improve clinical symptoms, motor function, and QoL in PwMS.

Fitness, physical activity, and exercise in multiple sclerosis: a systematic review on current evidence for interactions with disease activity and progression

Background

A moderate to high level of physical activity, including regular exercise, represents an established behavioral and rehabilitative approach for persons with multiple sclerosis (pwMS). Although being increasingly proposed to limit disease activity and progression, high-quality evidence is lacking.

Objective

The objective of the study is to provide valuable information for MS clinicians and researchers by systematically evaluating the current state of evidence (i) whether exercise interventions affect established clinical measures of disease activity and progression in pwMS (i.e., EDSS, relapse rate, lesion load, brain volume, MSFC) and (ii) how the physical activity and fitness level interact with these measures.

Methods

Literature search was conducted in MEDLINE, EMBASE, CINAHL, and SPORTDiscus. Evaluation of evidence quality was done based on standards published by The American Academy of Neurology.

Results

It is likely that exercise improves the MSFC score, whereas the EDSS score, lesion load, and brain volume are likely to remain unchanged over the intervention period. It is possible that exercise decreases the relapse rate. Results from cross-sectional studies indicate beneficial effects of a high physical activity or fitness level on clinical measures which, however, is not corroborated by high evidence quality.

Conclusions

A (supportive) disease-modifying effect of exercise in pwMS cannot be concluded. The rather low evidence quality of existing RCTs underlines the need to conduct more well-designed studies assessing different measures of disease activity or progression as primary end points. A major limitation is the short intervention duration of existing studies which limits meaningful exercise-induced effects on most disability measures. Findings from cross-sectional studies are difficult to contextualize regarding clinical importance due to their solely associative character and low evidence quality.

Impact of Moderate Individually Tailored Physical Activity in Multiple Sclerosis Patients with Fatigue on Functional, Cognitive, Emotional State, and Postural Stability

Multiple sclerosis (MS) is a chronic disease, with fatigue syndrome as one of the main symptoms. The aim of this study was to demonstrate that moderate physical activity (MPA) may have a beneficial effect on postural stability, balance, and clinical parameters. The research group consisted of 137 randomized patients hospitalized at the Department of Neurological Rehabilitation, Medical University of Lodz. Finally, 76 patients were qualified who were divided into two groups—high fatigue (HF) and low fatigue (LF). Participants were assessed twice: before and after a 4-week MPA program using: the Expanded Disability Status Scale (EDSS), the Fatigue Severity Scale (FSS), the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Beck Depression Inventory (BDI), and the Geriatric Depression Scale (GDS), and stabilometric platform tests were performed. Results obtained after the 4-week MPA program showed a positive effect of the MPA with differences between LF and HF groups. The MPA was more effective in MS patients with LF in cognitive functions, functional status, and postural stability but among HF patients in an emotional state, especially in MS patients below 65 years, although in total, both groups benefited from the MPA.

Motor Imagery: A Resource in the Fatigue Rehabilitation for Return-to-Work in Multiple Sclerosis Patients-A Mini Systematic Review

Fatigue is a multidimensional symptom with both physical and cognitive aspects, which can affect the quality of daily and working life activities. Motor Imagery (MI) represents an important resource for use during the rehabilitation processes, useful, among others, for job integration/reintegration, of neurological pathologies, such as Multiple Sclerosis (MS). To define the effective rehabilitation protocols that integrate MI for the reduction of fatigue in patients with MS (PwMS), a literary review was performed through August 2020. Five articles were included in the qualitative synthesis, including two feasibility pilot randomized control trials (RCTs) and 3 RCTs with good quality according to the PEDro score and a low risk of bias according to the Cochrane Collaboration tool. The literature suggested that MI, in association with rhythmic-auditory cues, may be an effective rehabilitation resource for reducing fatigue. Positive effects were observed on perceived cognitive and psychological fatigue. PwMS require greater compensatory strategies than healthy individuals, and the use of rhythmic-auditory cues may be useful for optimizing the cognitive processing of MI, which acts as an internal stimulus that is enhanced and made more vivid by outside cues. These findings provide evidence that MI is a promising rehabilitation tool for reducing fatigue in PwMS and return to work strategies.

Dosage and Effectiveness of Aerobic Training on Cardiorespiratory Fitness, Functional Capacity, Balance, and Fatigue in People With Multiple Sclerosis: A Systematic Review and Meta-Analysis

OBJECTIVES

To evaluate the benefits of aerobic training (AT) programs on cardiorespiratory fitness, functional capacity, balance, and fatigue in individuals with multiple sclerosis (MS) and to identify the optimal dosage of AT programs for individuals with MS via a systematic review with meta-analysis.

DATA SOURCES

Two electronic databases were searched until March 2020 (PubMed-Medline and Web of Science).

STUDY SELECTION

Studies examining the effect of AT program on cardiorespiratory fitness, functional capacity, balance, and fatigue were included.

DATA EXTRACTION

After applying the inclusion and exclusion criteria, we included 43 studies. A total sample of 1070 individuals with MS (AT group, n=680; control group, n=390) were analyzed.

DATA SYNTHESIS

The AT group demonstrated a significant increase in cardiorespiratory fitness (standardized mean difference [SMD], 0.29; P=.002), functional capacity (timed Up and Go Test: SMD, -1.14; P<.001; gait speed: SMD, -1.19; P<.001; walking endurance: SMD, 0.46; P<.001), and balance (SMD, 3.49; P<.001) after training. Fatigue perception also decreased (SMD, -0.45; P<.001). However, no significant differences were observed when compared with the control group in either cardiorespiratory fitness (SMD, 0.14; P=.19) or fatigue perception. Nevertheless, we observed significant differences between the AT and control groups in balance (P=.02), gait speed (P=.02), and walking endurance (P=.03), favoring the participants who performed AT. Regarding the subgroup analysis, no significant differences were observed between subgroups in any of the variables studied except for gait speed, for which a greater increase in posttraining was observed when the AT program applied the continuous method (χ²=7.75; P=.005) and the exercises were performed by walking (χ²=9.36; P=.002).

CONCLUSIONS

Aerobic training improves gait speed, walking endurance, and balance. Cardiorespiratory fitness and fatigue perception also improved after AT, but we found no differences with the control group. In addition, subgroup analysis suggested that training using continuous and walking methods could optimize gait speed.

Brain activity changes following neuroproprioceptive "facilitation, inhibition" physiotherapy in multiple sclerosis: a parallel group randomized comparison of two approaches

BACKGROUND

Imaging methods bring new possibilities for describing the brain plasticity processes that underly the improvement of clinical function after physiotherapy in people with multiple sclerosis (pwMS). Although these processes have been described mainly in connection with task-oriented physiotherapy and aerobic training, they have not been properly verified in neuroproprioceptive "facilitation, inhibition" (facilitation) approaches.

AIM

The study determined whether facilitation physiotherapy could enhance brain plasticity, compared two facilitation methods and looked for any relation to clinical improvement in pwMS.

DESIGN

The study was designed as parallel group randomized comparison of two kinds of physiotherapeutic interventions referred to healthy controls.

SETTING

Thirty-eight outpatients were involved in the study.

POPULATION

The study had 80 participants (38 pwMS and 42 healthy controls).

METHODS

PwMS were divided into two groups and underwent a two-month physiotherapy program: Vojta reflex locomotion (VRL) or Motor program activating therapy (MPAT), (1 hour, twice a week). Functional magnetic resonance imaging (fMRI) and clinical examination was performed before and after therapy. Healthy controls underwent one fMRI examination.

RESULTS

Physiotherapy in pwMS leads to extension of brain activity in specific brain areas (cerebellum, supplementary motor areas and premotor areas) in connection with the improvement of the clinical status of individual patients after therapy (P=0.05). Greater changes (P=0.001) were registered after MPAT than after VRL. The extension of activation was a shift to the examined activation of healthy controls, whose activation was higher in the cerebellum and secondary visual area (P=0.01).

CONCLUSIONS

Neuroproprioceptive "facilitation, inhibition" physiotherapy may enhance brain activity and could involve processes connected with the processing of motion activation.

CLINICAL REHABILITATION IMPACT

The study showed that facilitation approach can modulate brain activity. This could be useful for developing of effective physiotherapeutic treatment in MS.

Real-World Goal Setting and Use of Outcome Measures According to the International Classification of Functioning, Disability and Health: A European Survey of Physical Therapy Practice in Multiple Sclerosis

Goal setting is a core component of physical therapy in multiple sclerosis (MS). It is unknown whether and to what extent goals are set at different levels of the International Classification of Functioning, Disability and Health (ICF), and whether, and to which, standardized outcome measures are used in real life for evaluation at the different ICF levels. Our aim was to describe the real-world use of goal setting and outcome measures in Europe. An online cross-sectional survey, completed by 212 physical therapists (PTs) specialized in MS from 26 European countries, was conducted. Differences between European regions and relationships between goals and assessments were analyzed. PTs regularly set goals, but did not always apply the Specific, Measurable, Achievable, Realistic, Timed (SMART) criteria. Regions did not differ in the range of activities assessed, but in goals set (e.g., Western and Northern regions set significantly more goals regarding leisure and work) and outcome measures used (e.g., the Berg Balance Scale was more frequently used in Northern regions). Quality of life was not routinely assessed, despite being viewed as an important therapy goal. Discrepancies existed both in goal setting and assessment across European regions. ICF assists in understanding these discrepancies and in guiding improved health-care for the future.

Randomized comparison of functional electric stimulation in posturally corrected position and motor program activating therapy: treating foot drop in people with multiple sclerosis

BACKGROUND

Functional electric stimulation (FES) is recommended for foot drop in multiple sclerosis, although little is known about its therapeutic effect.

AIM

The aim of this study is to evaluate a therapeutic effect immediately and two months after program termination (persistent and delayed effect) of a new approach using FES in combination with correcting the patients' postural system. More specifically, we evaluate the effects of this approach on the patients' clinical functions and compared it with individual physiotherapy.

DESIGN

Parallel randomized blind trial.

SETTING

Two-month-long treatments, functional electric stimulation in posturally corrected position (group 1) and neuroproprioceptive facilitation and inhibition physiotherapy called motor program activating therapy (group 2).

POPULATION

Forty-four subjects with multiple sclerosis.

METHODS

Primary outcomes: gait (the 2-Minute Walk Test; Timed 25-Foot Walk test; Multiple Sclerosis Walking Scale-12) and balance (by e.g. Berg Balance Scale [BBS], the Activities-Specific Balance Confidence Scale [ABC], Timed Up-and-Go Test [TUG]).

SECONDARY OUTCOMES

mobility, cognition, fatigue and subjects' perceptions (e.g. Multiple Sclerosis Impact Scale [MSIS], Euroqol-5 dimensions-5 levels [EQ-5D-5L]).

RESULTS

Group 1 showed immediate therapeutic effect in BBS (P=0.008), ABC (P=0.04) and EQ-5D-5L (self-care, P=0.019, mobility P=0.005). The improvement in EQ-5D-5L persisted and in TUG-cognitive we documented a delayed effect (P=0.005). Group 2 showed an immediate improvement in BBS (P=0.025), MSIS (P=0.043) and several aspects of daily life (the effect on health today was significantly higher than in group 1, significant difference between groups P=0.038).

CONCLUSIONS

FES in the posturally corrected position has an immediate therapeutic effect on balance and patients' perceptions comparable to motor program activating therapy, and higher persistent and even delayed therapeutic effect.

CLINICAL REHABILITATION IMPACT

The study results point to the importance of correcting the patients' posture when applying FES, the possibility to treat foot drop by individual physiotherapy and the activation of the patients' auto reparative processes.

The impact of balance specific physiotherapy, intensity of therapy and disability on static and dynamic balance in people with multiple sclerosis: A multi-center prospective study

BACKGROUND

A high-quality research identifying the best physiotherapeutic approach for the improvement of balance in people with multiple sclerosis is missing. This study compared aspects of balance improvement such as therapy specificity to balance, therapy method and category, country, intensity and medical conditions.

METHODS

A multicentric randomised rater-blinded controlled trial comprised three different physiotherapy programs (Czech and Italian outpatient or inpatient programs). All patients received 20 therapy sessions. Experimental group underwent balance specific physiotherapy (it was Motor Program Activating Therapy in the Czech cohort and Sensory-motor Integration Training in the Italian cohort), control group underwent non-balance specific physiotherapy (it was Vojta reflex locomotion in the Czech cohort and conventional dynamic strengthening exercises in the Italian cohort, respectively). Static balance was evaluated by Berg Balance Scale and dynamic balance was assessed by Timed Up-and-Go Test.

RESULTS

A total of 149 patients entered the study. Physiotherapy significantly improved static balance (p < 0.0001, increase by mean 2.6 points (95% confidence interval 2.0-3.5) in BBS score). Balance specific approach had a higher effect than non-specific balance approach (increase in BBS by 1.9 points, 95% confidence interval 0.9-3.7 points). The intensity of the physiotherapy significantly influenced static balance (BBS by 2.7 points higher in the inpatient setting, p= 0.007). Dynamic balance was also improved (TUG decrease by -0.8 s (95% CI -1.4 - -0.1s, p = 0.011)); the balance specificity had no impact. The level of disability played the most important role (p= 0.022).

CONCLUSION

Although the overall changes in static and dynamic balance were statistically significant, they were quite small in a clinical sense. A small statistically significant difference between balance specific and non-specific treatment was found. It seems that a high intensity of the therapy is critical to maximize the effectiveness.

Respiratory repercussions of neurological diseases and how best to manage them

Introduction: The high incidence of respiratory impairments in patients with neurological diseases is recognized, but the design, dosage, and effectiveness of interventions to manage them are seen as an ongoing challenge.Areas covered: This article summarizes the evidence regarding the respiratory impairments in major neurological diseases, and how to best manage them.Expert opinion: On the balance of available evidence, respiratory impairments are part of the clinical profile of neurological diseases including Multiple Sclerosis, Stroke, and Parkinson's Disease, acquiring more importance as the pathologies progress. It is recognized that knowledge gaps remain in some areas of relevance related to respiratory function and further research is required. When considering the therapeutic options, the respiratory training emerges as the approach with most evidence. However, important questions remain unsolved: what kind, how much, and how to best include respiratory interventions is uncertain. At present, respiratory programs also fail to include clinically relevant factors such as ambulation and trunk stability.

Impact of pre-cooling therapy on the physical performance and functional capacity of multiple sclerosis patients: A systematic review

Patients with multiple sclerosis experience many complications that gradually lead them to comorbidity and disability. Exercise could prevent and ameliorate the symptoms that comorbidity or inactivity generate. However, until recently it was suggested that multiple sclerosis patients should not participate in exercise training programs because these patients are characterized by thermoregulatory failure and the heat stress due to physical work could exacerbate the disease symptoms. Furthermore, taken into account that 60-80% of the multiple sclerosis patients present adverse clinical symptoms when their body temperature is increased (not only due to physical working but even when immerse in hot water or by exposure to infrared lamps or to the sun), the need for the development of treatment strategies to overcome the thermoregulatory problem in these patients is crucial. Given that pre-cooling has been proposed as an effective method, the aim of this systematic review is to discuss the current knowledge for the effects of cooling therapy on the functional capacity of multiple sclerosis patients. The relevant literature includes many articles, but only a handful of studies published thus far have used a cooling intervention in multiple sclerosis patients and have examined the effects of pre-cooling on functional capacity. These studies used active cooling methods, namely garments or other material that are cooled by circulating liquid through a tube, as well as passive, cooling methods. Passive cooling methods include passive cooling garments or other material namely garments that have ice or gel packs inside them. Overall, the results of all the studies analysed in this review demonstrated that pre-cooling therapy can prevent the symptom worsening due to increased body temperature in multiple sclerosis patients without causing adverse effects. Therefore, such strategies could serve as a complimentary therapeutic approach in multiple sclerosis patients.

Metabolic, Mental and Immunological Effects of Normoxic and Hypoxic Training in Multiple Sclerosis Patients: A Pilot Study

Background: Physical activity might attenuate inflammation and neurodegeneration in multiple sclerosis (MS). Erythropoietin, which is produced upon exposure to hypoxia, is thought to act as a neuroprotective agent in MS. Therefore, we studied the effects of intermittent hypoxic training on activity energy expenditure, maximal workload, serum erythropoietin, and immunophenotype focusing on regulatory and IL-17A-producing T cells.

Methods: We assigned 34 relapsing-remitting MS patients within a randomized, single blind, parallel-group study to either normoxic (NO) or hypoxic (HO) treadmill training, both 3 times/week for 1 h over 4 weeks (Clinicaltrials.gov identifier: NCT02509897). Before and after training, activity energy expenditure (metabolic chamber), maximal workload (incremental treadmill test), walking ability, depressive symptoms (Beck Depression Inventory I), serum erythropoietin concentrations, and immunophenotype of peripheral blood mononuclear cells (PBMCs) were assessed.

Results: Energy expenditure did not change due to training in both groups, but was rather fueled by fat than by carbohydrate oxidation after HO training (P = 0.002). Maximal workload increased by 40 Watt and 42 Watt in the NO and HO group, respectively (both P < 0.0001). Distance patients walked in 6 min increased by 25 m and 27 m in the NO and HO group, respectively (NO P = 0.02; HO P = 0.01). Beck Depression Inventory score markedly decreased in both groups (NO P = 0.03; HO P = 0.0003). NO training shifted Treg subpopulations by increasing and decreasing the frequency of CD39⁺ and CD31⁺ Tregs, respectively, and decreased IL-17A-producing CD4⁺ cells. HO training provoked none of these immunological changes. Erythropoietin concentrations were within normal range and did not significantly change in either group.

Conclusion: 4 weeks of moderate treadmill training had considerable effects on fitness level and mood in MS patients, both under normoxic and hypoxic conditions. Additionally, NO training improved Th17/Treg profile and HO training improved fatty acid oxidation during exercise. These effects could not be attributed to an increase of erythropoietin.

Effect of Rehabilitation on Fatigue Level in Patients with Multiple Sclerosis

BACKGROUND The objective of this study was to evaluate the effect of a rehabilitation program in changing the perception of fatigue in patients with multiple sclerosis. MATERIAL AND METHODS The study involved 65 respondents/patients with clinically confirmed multiple sclerosis (54 women, 11 men, average age 46.49 years). The evaluation of the effects of fatigue on the physical, psychological, and psychosocial aspects of life was assessed using the Modified Fatigue Impact Scale (MFIS). To test the effectiveness of the neurorehabilitation program, we enrolled 2 groups: the experimental group (EG, n=32, 29 women, 3 men, Expanded Disability Status Scale (EDSS) 4.8 average, SD±1.77, min. 1.5 max 8.0) participated in the intervention and rehabilitation program over a period of 12 weeks and the control group (CG, n=33, 25 women, 8 men. EDSS average 5.12±1.74 SD, min. 2.0 max. 8.0). Each group of patients was divided into 3 sub-groups according to the severity of EDSS: a) 1-3.5, b) 4-6, and c) 6.5-8. For the statistical evaluation of the significance of the observed changes, the MANOVA/ANOVA model was used. RESULTS Between the input and output assessment of the MFIS individual areas questionnaire between the EG and the CG, there existed a statistically significant in the physical area (p<0.000), psychological area (p<0.000), and psychosocial area (p=0.002). CONCLUSIONS Our results support the importance of an active approach in patients with multiple sclerosis using individualized rehabilitation intervention programs.

Exercise Training in Progressive Multiple Sclerosis: A Comparison of Recumbent Stepping and Body Weight-Supported Treadmill Training

Background: There is evidence of the benefits of exercise training in multiple sclerosis (MS); however, few studies have been conducted in individuals with progressive MS and severe mobility impairment. A potential exercise rehabilitation approach is total-body recumbent stepper training (TBRST). We evaluated the safety and participant-reported experience of TBRST in people with progressive MS and compared the efficacy of TBRST with that of body weight-supported treadmill training (BWSTT) on outcomes of function, fatigue, and health-related quality of life (HRQOL). Methods: Twelve participants with progressive MS (Expanded Disability Status Scale scores, 6.0-8.0) were randomized to receive TBRST or BWSTT. Participants completed three weekly sessions (30 minutes) of exercise training for 12 weeks. Primary outcomes included safety assessed as adverse events and patient-reported exercise experience assessed as postexercise response and evaluation of exercise equipment. Secondary outcomes included the Multiple Sclerosis Functional Composite, the Modified Fatigue Impact Scale, and the Multiple Sclerosis Quality of Life-54 questionnaire scores. Assessments were conducted at baseline and after 12 weeks. Results: Safety was confirmed in both exercise groups. Participants reported enjoying both exercise modalities; however, TBRST was reviewed more favorably. Both interventions reduced fatigue and improved HRQOL (P ≤ .05); there were no changes in function. Conclusions: Both TBRST and BWSTT seem to be safe, well tolerated, and enjoyable for participants with progressive MS with severe disability. Both interventions may also be efficacious for reducing fatigue and improving HRQOL. TBRST should be further explored as an exercise rehabilitation tool for patients with progressive MS.

Aerobic capacity in persons with multiple sclerosis: a systematic review and meta-analysis

BACKGROUND

Aerobic capacity (VO2max) is a strong health and performance predictor and is regarded as a key physiological measure in the healthy population and in persons with multiple sclerosis (PwMS). However, no studies have tried to synthesize the existing knowledge regarding VO2max in PwMS.

OBJECTIVES

The objectives of this study were to (1) systematically review the psychometric properties of the VO2max test; (2) systematically review the literature on VO2max compared with healthy populations; (3) summarize correlates of VO2max; and (4) to review and conduct a meta-analysis of longitudinal exercise studies evaluating training-induced effects on VO2max in PwMS.

DATA SOURCES AND STUDY SELECTION

A systematic literature search of six databases (PubMed, EMBASE, Cochrane Library, PEDro, CINAHL and SPORTDiscus) was performed. To be included, the study had to (1) enrol participants with definite MS according to defined criteria; (2) assess aerobic capacity (VO2max) by means of a graded exercise test to voluntary exhaustion; (3) had undergone peer review; and (4) be available in English, Danish or Dutch.

STUDY APPRAISAL AND SYNTHESIS METHODS

The psychometric properties of the VO2max test in PwMS were reviewed with respect to reliability, validity and responsiveness. Simple Pearson correlation analysis was used to assess the relation between key study characteristics and the reported mean VO2max. The methodological quality of the intervention studies was evaluated using the original 11-item Physiotherapy Evidence Database (PEDro) scale. A random coefficient model was used to summarize individual, weighted, standardized effects of studies that assessed the effects of exercise on aerobic capacity in PwMS.

RESULTS

A total of 40 studies, covering 165 healthy controls and 1,137 PwMS, fulfilled the inclusion criteria. VO2max testing in PwMS can be considered a valid measure of aerobic capacity, at least in PwMS having low-to-mild disability, and an ∼10% change between two tests performed on separate days can be considered the smallest reliable change (with 95% certainty) in VO2max in PwMS. The average body-weight-adjusted VO2max was significantly lower in PwMS (25.5 ± 5.2 mL·kg(-1)·min(-1)) compared with healthy controls (30.9 ± 5.4 mL·kg(-1)·min(-1)). The analysis of VO2max correlates revealed associations with a variety of outcomes covering all levels of the International Classification of Functioning, Disability and Health (ICF) model. The meta-analysis showed that aerobic training in PwMS may improve VO2max by as much as 3.5 mL·kg(-1)·min(-1).

CONCLUSIONS

A valid and reliable test can be performed, in at least ambulant PwMS, by the gold standard whole-body maximal exercise test. Aerobic capacity in PwMS is impaired compared with healthy people, and is significantly associated with factors on all levels of the ICF model, including disease severity. Aerobic training can improve aerobic capacity in PwMS to a degree that is associated with secondary health benefits.

Reliability and Validity of Ratings of Perceived Exertion in Persons With Multiple Sclerosis

OBJECTIVE

To test the reliability and validity of using the Borg rating of perceived exertion (RPE) scale (ratings 6-20) in persons with multiple sclerosis (PwMS).

DESIGN

Nonrandomized repeated measures.

SETTING

Research laboratory.

PARTICIPANTS

Volunteer sample (N=27) comprised of 16 PwMS (10 women) and 11 age-matched persons without multiple sclerosis (MS) (6 women). Clinical measures included symptomatic fatigue, depression, and MS functional capacity.

INTERVENTIONS

A submaximal cycling test was performed to estimate maximal capacity. Participants then pedaled for 2 minutes at 50% and 60% of predicted maximal oxygen consumption per unit time (V˙o2), and physiological measures and RPE were obtained (week 1: response protocol). One week later, participants replicated the prescribed V˙o2 using the RPE range from week 1 (week 2: reproduction protocol). V˙o2, heart rate, and respiratory quotient were measured continuously; RPE and workload were measured every minute; and blood lactate and mean arterial pressure were measured after exercise.

MAIN OUTCOME MEASURES

RPE, workload, V˙o2, and heart rate from week 1 to week 2.

RESULTS

PwMS had greater fatigue (P<.01) and disability (P<.001). Baseline measures were similar between groups and weeks. During exercise, RPE, workload, V˙o2, and heart rate were similar between groups. Both groups had an intraclass correlation coefficient >.86 for RPE, workload, and V˙o2. The intraclass correlation coefficient was comparatively lower for heart rate for both groups (MS group: .72, non-MS group: .83). RPE was highly correlated with V˙o2 (r=.691, P<.001) and workload (r=.700, P<.001) for the MS group.

CONCLUSIONS

Results suggest that RPE can be reliably reproduced, is valid, and may be used in exercise prescription in mildly to moderately impaired PwMS during cycling exercise.

Exercise therapy for fatigue in multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system affecting an estimated 1.3 million people worldwide. It is characterised by a variety of disabling symptoms of which excessive fatigue is the most frequent. Fatigue is often reported as the most invalidating symptom in people with MS. Various mechanisms directly and indirectly related to the disease and physical inactivity have been proposed to contribute to the degree of fatigue. Exercise therapy can induce physiological and psychological changes that may counter these mechanisms and reduce fatigue in MS.

OBJECTIVES

To determine the effectiveness and safety of exercise therapy compared to a no-exercise control condition or another intervention on fatigue, measured with self-reported questionnaires, of people with MS.

SEARCH METHODS

We searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Trials Specialised Register, which, among other sources, contains trials from: the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 10), MEDLINE (from 1966 to October 2014), EMBASE (from 1974 to October 2014), CINAHL (from 1981 to October 2014), LILACS (from 1982 to October 2014), PEDro (from 1999 to October 2014), and Clinical trials registries (October 2014). Two review authors independently screened the reference lists of identified trials and related reviews.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) evaluating the efficacy of exercise therapy compared to no exercise therapy or other interventions for adults with MS that included subjective fatigue as an outcome. In these trials, fatigue should have been measured using questionnaires that primarily assessed fatigue or sub-scales of questionnaires that measured fatigue or sub-scales of questionnaires not primarily designed for the assessment of fatigue but explicitly used as such.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected the articles, extracted data, and determined methodological quality of the included trials. Methodological quality was determined by means of the Cochrane 'risk of bias' tool and the PEDro scale. The combined body of evidence was summarised using the GRADE approach. The results were aggregated using meta-analysis for those trials that provided sufficient data to do so.

MAIN RESULTS

Forty-five trials, studying 69 exercise interventions, were eligible for this review, including 2250 people with MS. The prescribed exercise interventions were categorised as endurance training (23 interventions), muscle power training (nine interventions), task-oriented training (five interventions), mixed training (15 interventions), or 'other' (e.g. yoga; 17 interventions). Thirty-six included trials (1603 participants) provided sufficient data on the outcome of fatigue for meta-analysis. In general, exercise interventions were studied in mostly participants with the relapsing-remitting MS phenotype, and with an Expanded Disability Status Scale less than 6.0. Based on 26 trials that used a non-exercise control, we found a significant effect on fatigue in favour of exercise therapy (standardized mean difference (SMD) -0.53, 95% confidence interval (CI) -0.73 to -0.33; P value < 0.01). However, there was significant heterogeneity between trials (I(2) > 58%). The mean methodological quality, as well as the combined body of evidence, was moderate. When considering the different types of exercise therapy, we found a significant effect on fatigue in favour of exercise therapy compared to no exercise for endurance training (SMDfixed effect -0.43, 95% CI -0.69 to -0.17; P value < 0.01), mixed training (SMDrandom effect -0.73, 95% CI -1.23 to -0.23; P value < 0.01), and 'other' training (SMDfixed effect -0.54, 95% CI -0.79 to -0.29; P value < 0.01). Across all studies, one fall was reported. Given the number of MS relapses reported for the exercise condition (N = 25) and non-exercise control condition (N = 26), exercise does not seem to be associated with a significant risk of a MS relapse. However, in general, MS relapses were defined and reported poorly.

AUTHORS' CONCLUSIONS

Exercise therapy can be prescribed in people with MS without harm. Exercise therapy, and particularly endurance, mixed, or 'other' training, may reduce self reported fatigue. However, there are still some important methodological issues to overcome. Unfortunately, most trials did not explicitly include people who experienced fatigue, did not target the therapy on fatigue specifically, and did not use a validated measure of fatigue as the primary measurement of outcome.

Effectiveness of Group Versus Individual Yoga Exercises on Fatigue of Patients with Multiple Sclerosis

Background:

Multiple sclerosis disorders poses heavy physical and emotional effect on patients who are associated with the disease.

Aim:

This study aimed to compare the effectiveness of individual versus group exercises on fatigue on patients with multiple sclerosis.

Materials and Methods:

In this clinical trial, 85 patients with multiple sclerosis were divided in two groups of individualized exercise and team exercise. The intervention was conducted for 6 weeks and comprised of mild stretching and basic yoga exercises twice a day. The data were collected through demographic questionnaire, standard fatigue scale and self-reported checklist. Data analysis was performed by SPSS software.

Results:

The mean levels of fatigue perception after the intervention in group exercise was 27.9 ± 15.9 and 27.1 ± 17.2 in individual exercise. There was no significant difference between the two groups (P > 0.05). Statistically significant difference was observed in the mean level of perceived fatigue in triplicate measurements (P = 0.013) among patients who completed individual exercise. However, this difference was not significant in the group exercise.

Conclusion:

Performing mild stretching exercises and basic yoga are recommended as a cost-effective method which is easy to perform among patients with mild to moderate disabilities.

Reliability and responsiveness of cardiopulmonary exercise testing in fatigued persons with multiple sclerosis and low to mild disability

Background

Peak oxygen uptake (VO₂peak) via cardiopulmonary exercise testing is considered the gold standard for testing aerobic capacity in healthy participants and people with various medical conditions. The reliability and responsiveness of cardiopulmonary exercise testing outcomes in persons with MS (PwMS) have not been extensively studied.

Objective

(1) to investigate the reliability of cardiopulmonary exercise parameters in PwMS; (2) to determine the responsiveness, in terms of the smallest detectable change (SDC), for each parameter.

Design

Two repeated measurements of cardiopulmonary exercise outcomes were obtained, with a median time interval of 16 days.

Methods

Thirty-two PwMS suffering from subjective fatigue performed cardiopulmonary exercise tests on a cycle ergometer, to voluntary exhaustion. We calculated the reliability, in terms of the intra-class correlation coefficient (ICC [2,k]; absolute agreement), and the measurement error, in terms of standard error of measurement (SEM) and SDC at individual (SDC_individual) and group level (SDC_group).

Results

The ICC for VO₂peak was 0.951, with an SEM of 0.131 L∙min⁻¹ and an SDC_individual of 0.364 L∙min⁻¹. When corrected for bodyweight, the ICC of VO₂peak was 0.933, with an SEM of 1.7 mL∙kg⁻¹∙min⁻¹ and in an SDC_individual of 4.6 mL∙kg⁻¹∙min⁻¹.

Limitations

Generalization of our study results is restricted to fatigued PwMS with a low to mild level of disability.

Conclusions

At individual level, cardiopulmonary exercise testing can be used reliably to assess physical fitness in terms of VO₂peak, but less so to determine significant changes. At group level, VO₂peak can be reliably used to determine physical fitness status and establish change over time.

Management of fatigue in persons with multiple sclerosis

Fatigue is one of the most common symptoms of multiple sclerosis. Despite advances in pharmacological and non-pharmacological treatment, fatigue continues to be the disabling symptom in persons with MS (pwMS), affecting almost 80% of pwMS. In current practice, both pharmacological and non-pharmacological interventions are used in combination, encompassing a multi-disciplinary approach. The body of research investigating the effect of these interventions is growing. This review systematically evaluated the existing evidence on the effectiveness and safety of different interventions currently applied for the management of fatigue in person with multiple sclerosis in improving patient outcomes, to guide treating clinicians.

Energy expenditure during everyday activities--a study comparing people with varying mobility limitations due to multiple sclerosis and healthy controls

PURPOSE

To investigate energy expenditure of people with multiple sclerosis (MS) during everyday activities.

METHODS

Fifteen healthy controls, 19 people with MS who used at most a stick to walk outdoors (MS-A), and 11 people with MS who used bilateral support for gait (MS-B) completed scripted everyday activities. A portable indirect calorimetry unit calculated energy expenditure. Steps were counted from video.

RESULTS

There was no significant difference in kcal between the three groups (ANOVA: F(2, 42) = 2.877, p = 0.067). There was a significant difference in steps: F(2, 42) = 17.93, p < 0.001. (Controls-MS-A 470.5, 95% CI 85.2, 855.7, Control-MS-B 1091.3, 95% CI 648.5, 1534.1, MS-A-MS-B 620.8, 95% CI 198.2, 1043.4.) Energy cost of movement was estimated by dividing kcal by steps. The Kruskal-Wallis analysis found significant difference for total (x(2 )= 11.726, df2, p = 0.003), Walking (x(2 )= 9.01, p = 0.011), Stairs (x(2 )= 16.436, 2, p < 0.001). Post-hoc analysis revealed significant differences between MS-B group and control and MS-A groups.

CONCLUSIONS

People with MS do not use more energy than healthy controls during everyday activities at a self-selected pace. People with MS take significantly fewer steps during activities of daily living's. People who use bilateral support for gait have greater energy cost per step for walking and stairs activities. Implications for Rehabilitation This study found that the energy cost of movement is greater for people with MS with significant disability. Energy expenditure is an important consideration when prescribing physical activity and structured exercise for people with disability. It may be more appropriate to have energy, rather than movement, targets when prescribing physical activity for this population.

The Effect of Community Exercise Interventions for People with MS Who Use Bilateral Support for Gait

Background. Mobility limitations are a key feature of MS and 25% will require the use of a walking aid 15 years after diagnosis. Few studies have specifically evaluated the effectiveness of physiotherapy and exercise interventions delivered in the community for those with significant disability. Methods. An assessor blind, block randomised, and controlled study recruited participants who required bilateral assistance for gait and who occasionally used wheelchairs for longer distances. They were randomised to 10 weeks of group physiotherapy (balance and strengthening exercises), individual physiotherapy, yoga group, or a control group. Results. Repeated measures ANOVA found significant time effects for physical component of MSIS-29v2 (f = 7.993, P = 0.006) and MFIS (f = 8.695, P = 0.004). The group × time interaction was significant for the BBS (f = 4.391, P = 0.006). Post hoc analysis revealed no difference between group and individual physiotherapy for BBS. There was no significant difference between groups but the 6MWT improved for individual physiotherapy (P = 0.001) and MSIS-29v2 psychological score for group physiotherapy (P = 0.005). Discussion. This study found that balance and strengthening exercises, delivered in the community to those with significant mobility limitations, improve balance. The effect on walking endurance and patient-reported outcomes are unclear and warrants further investigation with a larger control group with similar baseline characteristics to the intervention groups.

Training in MS: influence of two different endurance training protocols (aquatic versus overland) on cytokine and neurotrophin concentrations during three week randomized controlled trial

BACKGROUND

The influences of exercising on cytokine response, fatigue and cardiorespiratory values are important aspects of rehabilitation in persons with multiple sclerosis (PwMS). Exercise performed within these programs is often practised in water but the effects of immersion on PwMS have not been systematically investigated.

OBJECTIVE

The objective of this study is to determine differences in cytokine and neurotrophin concentrations, fatigue and cardiorespiratory values in response to 3 week endurance training conducted on a cycle ergometer or an aquatic bike.

METHODS

A randomized controlled clinical trial was conducted in 60 MS patients (Expanded Disability Status Scale range 1.0-6.5). Resting serum levels of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), Interleukin-6, soluble receptor of IL-6 and tumor necrosis factor alpha, and concentrations in response to cardiopulmonary exercise test (CPET), fatigue and cardiorespiratory values were determined at entry and discharge. Subjects performed daily 30 minute training at 60% of VO₂max.

RESULTS

Cytokines and neurotrophins showed no significant differences between groups over the training intervention. Within the water group BDNF resting and post-CPET concentrations (p<0.05) showed a significant increase and NGF tended to increase after the training intervention. Short-term effects on BDNF (CEPT) tended to increase at the start and significantly thereafter (p<0.05). No changes occurred in the land group. Other cytokines and fatigue scores remained unchanged over the training period. Cardiorespiratory values improved significantly over time within both groups.

CONCLUSION

This study indicates that aquatic training activates BDNF regulation and can be an effective training method during rehabilitation in PwMS.

Fatigue after Stroke: A Systematic Review of Associations with Impaired Physical Fitness

Background

Fatigue is a common and distressing post stroke symptom. One important hypothesis is that fatigue after stroke may be triggered by physical deconditioning, which sets up a vicious, self-perpetuating cycle of fatigue, avoidance of physical activity, further deconditioning, and more fatigue. If an association between physical activity and fatigue after stroke could be established, this would provide a rationale for developing a physical activity-based treatment.

Aims

Systematically review all observational studies, which have measured both fatigue poststroke and one or more measures of physical fitness and/or physical activity at the same time-point and reported the association between fatigue and fitness variables.

Method

Publications were identified by systematically searching databases MEDLINE, EMBASE, CINAHL, PsychInfo, and Sportdiscus using keywords ‘fatigue’, ‘stroke’, ‘fitness’, or ‘activity’ and their associated terms or synonyms. Publications that provided data on associations between fatigue in stroke patients and levels of physical activity, cardiorespiratory fitness and/or muscle strength and mass were included.

Results

Twenty-nine potential studies were retrieved after scrutinizing the titles and abstracts, of which only three fulfilled our inclusion criteria. No association between fatigue and any measures of physical activity or fitness were found. One study did find, through structural equation modeling techniques that fatigue indirectly influences exercise through self-efficacy expectations.

Conclusions

There is very limited evidence regarding associations between exercise, fitness, and fatigue after stroke. It still remains highly plausible that exercise can have a positive influence on fatigue. Future research should be longitudinal in design.

Exercise in multiple sclerosis -- an integral component of disease management

Multiple sclerosis (MS) is the most common chronic inflammatory disorder of the central nervous system (CNS) in young adults. The disease causes a wide range of symptoms depending on the localization and characteristics of the CNS pathology. In addition to drug-based immunomodulatory treatment, both drug-based and non-drug approaches are established as complementary strategies to alleviate existing symptoms and to prevent secondary diseases. In particular, physical therapy like exercise and physiotherapy can be customized to the individual patient's needs and has the potential to improve the individual outcome. However, high quality systematic data on physical therapy in MS are rare. This article summarizes the current knowledge on the influence of physical activity and exercise on disease-related symptoms and physical restrictions in MS patients. Other treatment strategies such as drug treatments or cognitive training were deliberately excluded for the purposes of this article.

Objective assessment of motor fatigue in Multiple Sclerosis using kinematic gait analysis: a pilot study

Background

Fatigue is a frequent and serious symptom in patients with Multiple Sclerosis (MS). However, to date there are only few methods for the objective assessment of fatigue. The aim of this study was to develop a method for the objective assessment of motor fatigue using kinematic gait analysis based on treadmill walking and an infrared-guided system.

Patients and methods

Fourteen patients with clinically definite MS participated in this study. Fatigue was defined according to the Fatigue Scale for Motor and Cognition (FSMC). Patients underwent a physical exertion test involving walking at their pre-determined patient-specific preferred walking speed until they reached complete exhaustion. Gait was recorded using a video camera, a three line-scanning camera system with 11 infrared sensors. Step length, width and height, maximum circumduction with the right and left leg, maximum knee flexion angle of the right and left leg, and trunk sway were measured and compared using paired t-tests (α = 0.005). In addition, variability in these parameters during one-minute intervals was examined. The fatigue index was defined as the number of significant mean and SD changes from the beginning to the end of the exertion test relative to the total number of gait kinematic parameters.

Results

Clearly, for some patients the mean gait parameters were more affected than the variability of their movements while other patients had smaller differences in mean gait parameters with greater increases in variability. Finally, for other patients gait changes with physical exertion manifested both in changes in mean gait parameters and in altered variability. The variability and fatigue indices correlated significantly with the motoric but not with the cognitive dimension of the FSMC score (R = -0.602 and R = -0.592, respectively; P < 0.026).

Conclusions

Changes in gait patterns following a physical exertion test in patients with MS suffering from motor fatigue can be measured objectively. These changes in gait patterns can be described using the motor fatigue index and represent an objective measure to assess motor fatigue in MS patients. The results of this study have important implications for the assessments and treatment evaluations of fatigue in MS.

Treatment of fatigue in multiple sclerosis patients: a neurocognitive approach

The objective of the study was to treat fatigue in patients with multiple sclerosis (MS) by a neurocognitive rehabilitation program aimed at improving motor planning by using motor imagery (MI). Twenty patients with clinically definite MS complaining of fatigue were treated for five weeks with exercises of neurocognitive rehabilitation twice a week. Patients were evaluated by Fatigue Severity Scale (FSS), Modified Fatigue Impact Scale (MFIS), MSQoL54, Expanded Disability Status Scale (EDSS), and MS Functional Composite (MSFC). After treatment, a decrease in fatigue was detected with both FSS (P = 0.0001) and MFIS (P = 0.0001). MSFC (P = 0.035) and MSQoL54 (P = 0.002) scores improved compared to baseline. At six-month followup, the improvement was confirmed for fatigue (FSS, P = 0.0001; MFIS P = 0.01) and for the physical subscale of MSQoL54 (P = 0.049). No differences in disability scales were found. These results show that neurocognitive rehabilitation, based on MI, could be a strategy to treat fatigue in MS patients.

Symptomatic therapy in multiple sclerosis

Multiple sclerosis is the most common disabling neurological disease of young adults. The ability to impact the quality of life of patients with multiple sclerosis should not only incorporate therapies that are disease modifying, but should also include a course of action for the global multidisciplinary management focused on quality of life and functional capabilities.

Fractional anisotropy and mean diffusivity in the corpus callosum of patients with multiple sclerosis: the effect of physiotherapy

INTRODUCTION

Modulation of neurodegeneration by physical activity is an active topic in contemporary research. The purpose of this study was to investigate changes in the brain's microstructure in multiple sclerosis (MS) after facilitation physiotherapy.

METHODS

Eleven patients with MS were examined using motor and neuropsychological testing and multimodal MRI at the beginning of the study, with second baseline measurement after 1 month without any therapy, and after a 2-month period of facilitation physiotherapy. Eleven healthy controls were examined at the beginning of the study and after 1 month. Fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (λ (ax)), and radial diffusivity (λ (rad)) were calculated for the whole corpus callosum (CC) in the midsagittal slice of T1W 3D MPRAGE spatially normalized images. Data were analyzed using linear mixed-effect models, paired, and two-sample tests.

RESULTS

At the baseline, patients with MS showed significantly lower values in FA (p < 0.001), and significantly higher values in MD (p < 0.001), λ (ax) (p = 0.003), and λ (rad) (p < 0.001) compared to control subjects. The FA, MD, λ (ax), and λ (rad) did not change between the first and second baseline examinations in either group. Differences 2 months after initiating facilitation physiotherapy were in FA, MD, and in λ (rad) significantly higher than differences in healthy controls (p < 0.001 for FA, p = 0.02 for MD, and p = 0.002 for λ (rad)). In MS patients, FA in the CC significantly increased (p < 0.001), MD and λ (rad) significantly decreased (p = 0.014 and p = 0.002), and thus approached the values in healthy controls.

CONCLUSION

The results of the study show that facilitation physiotherapy influences brain microstructure measured by DTI.

The effect of exercise therapy on fatigue in multiple sclerosis

Background: Fatigue occurs in the majority of patients with multiple sclerosis (MS) and therapeutic possibilities are few. Exercise therapy is a therapeutic option but no studies have systematically reviewed the existing literature evaluating the effect of exercise therapy on MS fatigue.

Objective: To determine the effect of exercise therapy on MS fatigue by systematically reviewing the literature.

Methods: A comprehensive literature search (PubMed, SweMed +, Embase, Cochrane, CINAHL, PEDro, Sport Discuss and Bibliotek.dk) was conducted.

Results: Studies evaluating the effect of exercise therapy on MS fatigue show heterogeneous results and only few studies have evaluated MS fatigue as the primary outcome. The heterogeneous findings seem to be related to the selected study population, which in many studies are non-fatigued. Most studies that have included fatigued patients with MS show positive effects, although it is not clear whether any exercise modalities are superior to others because there are no comparative studies regarding different exercise interventions.

Conclusion: Exercise therapy has the potential to induce a positive effect on MS fatigue, but findings are heterogeneous probably because many studies have applied non-fatigued study populations. Furthermore, only few studies have evaluated MS fatigue as the primary outcome measure, emphasizing the need for future studies within this field.
