Combined upper limb and breathing exercise programme for pain management in ambulatory and non-ambulatory multiple sclerosis individuals: part II analyses from feasibility study

Effect of different types of exercise on fitness in people with multiple sclerosis: A network meta-analysis

BACKGROUND

It is assumed that people with multiple sclerosis (MS) who participate in programs of physical exercise improve their physical fitness.

OBJECTIVE

The aim of this network meta-analysis (NMA) was to analyze the effect of different types of exercise on muscular fitness and cardiorespiratory fitness (CRF) among people with MS and to determine the best type of exercise according to disease severity.

METHODS

MEDLINE, the Physiotherapy Evidence Database, the Cochrane Library, SPORTDiscus, Scopus, and Web of Science were searched from inception to April 2022 to identify randomized controlled trials (RCTs) concerning the effect of physical exercise on fitness in people with MS. We ranked the types of physical exercise by calculating the surface under the cumulative ranking (SUCRA).

RESULTS

We included 72 RCTs involving 2543 MS patients in this NMA. A ranking of five types of physical exercise (aerobic, resistance, combined [aerobic and resistance], sensorimotor training, and mind-body exercises) was achieved. Combined and resistance training had the highest effect sizes (0.94, 95% CI 0.47, 1.41, and 0.93, 95% CI 0.57, 1.29, respectively) and the highest SUCRA (86.2% and 87.0%, respectively) for muscular fitness. The highest effect size (0.66, 95% CI 0.34, 0.99) and SUCRA (86.9%) for CRF was for aerobic exercise.

CONCLUSIONS

Combined and resistance training seem to be the most effective exercises to improve muscular fitness and aerobic exercise for CRF in people with MS.

Yoga and Multiple Sclerosis: Maintaining engagement in physical activity

BACKGROUND

Physical activity is encouraged for people with Multiple Sclerosis. Yoga is a popular form of physical activity and is chosen by some people with Multiple Sclerosis. However, little is known about the impact of yoga for this population, alongside what influences ongoing engagement.

AIM

The aim of this study is to qualitatively explore the impact of online home-based yoga on people with Multiple Sclerosis and to explore factors that influence engagement.

METHODS

A qualitative study using semi-structured interviews and focus groups with people with Multiple Sclerosis and a yoga teacher. Thematic analysis was used to analyse the data. Ethical Approval was gained from Northumbria University.

FINDINGS

Three overarching themes emerged from the analysis. 'Yoga as engagement in physical activity' captured the reasoning for participating in yoga and how this method of physical activity was an alternative to physical activity done prior to diagnosis. Frustration was apparent within this theme that some individuals were unable to engage in the range of physical activity that they wished to. 'Yoga is a personalised approach' demonstrated the flexibility and inclusivity of yoga, for individuals with varying symptoms to be able to engage with. Finally, 'yoga impacts individuals both physically and psychologically' captured the focus on the psychological impact of yoga, improving wellbeing and control.

CONCLUSIONS

Yoga gives people with Multiple Sclerosis the feeling of control over their symptoms and a means to engage with meaningful physical activity. Prior involvement in physical activity influenced engagement in yoga and wanting to push themselves. There was reluctance among this group to engage with aerobic activity, which warrants future investigation and support from health and exercise professionals.

Upper-lower limb and breathing exercise program for improving sleep quality and psychological status in multiple sclerosis: a pilot randomized controlled trial

PURPOSE

To examine the feasibility and possible effect of an 8-week exercise program on sleep quality, insomnia and psychological distress in individuals with multiple sclerosis (MS).

METHODS

Twenty-four individuals with MS were recruited into a controlled pre-post feasibility study and divided into 2 groups: exercise (n = 13; Expanded Disability Status Scale (EDSS): 1.0-7.5) and a related control group with no exercise (n = 11; EDSS: 1.0-7.0). The exercise group performed combined upper limb, lower limb and breathing exercises in a controlled group (2d/week, 60 min/session) for 8 weeks. Participants were administered measures to evaluate sleep quality (Pittsburgh Sleep Quality Index, PSQI), insomnia severity (Insomnia Severity Index, ISI), psychological distress (Clinical Outcomes in Routine Evaluation-Outcome Measure, CORE-OM) and additionally impact of fatigue (Modified Fatigue Impact Scale, MFIS) after 8-weeks.

RESULTS

Insomnia severity measured with ISI (F(1;22)=5.95, p = 0.023, η p 2 = 0.213, 90% CI = 0.02-0.42) and psychological distress measured with the CORE-OM (F(1;22)=4.82, p = 0.039, η p 2 = 0.179, 90% CI = 0.01-0.40) showed statistically significant group-by-time interaction. Sleep quality measured with the PSQI showed statistically significant group-by-time interaction only in an aspect of daytime sleep dysfunction (F(1;22)=5.33, p = 0.031, η p 2 = 0.195, 90% CI = 0.01-0.40). The fatigue impact measured with the MFIS showed statistically significant group-by-time interaction in physical (F(1;22)=6.80, p = 0.016, η p 2 = 0.236, 90% CI = 0.02-0.44) and cognitive aspects (F(1;22)=9.12, p = 0.006, η p 2 = 0.293, 90% CI = 0.05-0.49), and total score (F(1;22)=11.29, p = 0.003, η p 2 = 0.339, 90% CI = 0.08-0.52).

CONCLUSIONS

Our 8-week program reduced insomnia severity, psychological distress and some aspects of fatigue (physical; cognitive; total), and improved sleep quality in an aspect of daytime sleep dysfunction in a small group of individuals with MS. Good feasibility and significant positive changes from baseline warrant further exploratory work.

Comparing Two Protocols of Exercise on Physical Fitness and Psychological Factors of Mild to Moderate Multiple Sclerosis Patients

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS). Previous studies have shown that aerobic activity is inversely related to MS symptoms and may be restorative and possibly protective. Objectives: This study aimed to compare the effects of high-intensity functional training (HIFT) protocols and aerobic exercise on functional fitness as well as the cognitive aspect of female patients with multiple sclerosis. Methods: This quasi-experimental and applied clinical trial study consisted of all patients with MS registered in an MS clinic. Among eligible individuals, 30 female RRMS patients were randomly and equally divided into three groups high-intensity functional training (n = 10); aerobic exercise (n = 10), and control group (n = 10). The forearm test, the 30-second standing test, and single leg stance test (SLST), The Timed Up and Go (TUG), expanded disability status scale (EDSS) were performed to assess physical factors as well as the 21-DAS questionnaire to assess cognitive aspects. Results: This study showed a meaningful difference between the intervention groups and the control group (P < 0.05), in the level of power in the upper body (P = 0.001), Lower torso strength (P = 0.001), Static balance (P = 0.001), Dynamic balance (P = 0.001). the psychological and behavioral components. Conclusions: Present study suggests that aerobic exercise and HIFT in women with MS can improve and further enhance physical function plus psychological and behavioral factors.

Breathing Exercises for Pain Management in Cancer Survivors: A Systematic Review

OBJECTIVES

Unmanaged pain significantly affects cancer survivors' quality of life. Nurses should play a significant role in pain management through non-pharmacological interventions. This review aims to explore the efficacy and safety of breathing exercises for pain management in all cancer survivors.

DESIGN

A systematic review.

DATA SOURCES

Thirteen databases, including PubMed, EMBase, CENTRAL, MEDLINE, CINAHL, JBI, Science Direct, Scopus, SocINDEX, Web of Science, PsycINFO, CNKI, and Wan Fang, were searched from inception to May, 2021.

REVIEW/ANALYSIS METHODS

Studies that focused on the efficacy of breathing exercises for pain management, regardless of the age of the cancer survivors, were included. Cochrane tools were used for the quality appraisal of the included studies. Because of the limited number of studies, descriptive data analysis was used to summarize the results.

RESULTS

Ten studies were included. Slow pursed lip breathing showed benefits for post-surgical pain. Contradictory findings were identified in the Enhanced Recovery After Surgery for post-surgical pain. Slow deep breathing and Hey-Hu regular breathing techniques were effective for pain management in pediatric cancer patients. The Active Cycle of Breathing Technique and five-minute mindful breathing did not have any statistically significant effects on pain relief. Quality of life was measured in three studies, with some improvement. Only one study addressed adverse events and reported that no adverse events occurred.

CONCLUSIONS

Breathing exercises may be a promising approach to pain relief in cancer survivors. However, more rigorously designed studies are required to establish the evidence.

Effectiveness of non-pharmacological rehabilitation interventions in pain management in patients with multiple sclerosis: Systematic review and meta-analysis

BACKGROUND

Multiple sclerosis (MS) is a progressive inflammatory and autoimmune neurological disease caused by inflammation and demyelination of the central nervous system. Pain is a typical symptom of central nervous system demyelination, affecting 63% of adults with MS. Recently, the role of non-pharmacological pain management in patients is growing because the non-pharmacological interventions are considered safe, affordable, easy, and accessible. However, to date, no systematic reviews or meta-analyses have comprehensively examined the therapeutic effects of the variety of non-pharmacological therapeutic interventions in the management of pain in patients with MS.

OBJECTIVE

The study aimed to conduct a systematic review with meta-analysis to assess the effectiveness of the non-pharmacological rehabilitation interventions in pain management in patients with MS.

METHODS

A comprehensive search using PubMed, Cochrane, and Science Direct databases was performed and included all randomized controlled trials, randomized cross-over trials, and quasi-experimental trials assessing the effect of non-pharmacological interventions for managing pain in patients with MS. This study was conducted according to PRISMA guidelines of a systematic review and pair-wise meta-analysis. Meta-analyses were performed by calculating the standardized mean difference at a 95% confidence interval using Review Manager software.

RESULTS

Twenty-nine papers were included in the systematic review, and only 22 of them were included in the meta-analysis. The pooled analysis showed a significant effect of neuromodulation and transcranial direct current stimulation on pain intensity reduction in patients with MS (SMD -0.51, 95% CI -0.51 to -0.09, P = 0.02), (SMD -0.67, 95% CI -1.18 to -0.16 P = 0.01), respectively. The analysis showed significant improvement in pain intensity in patient with MS after mind-body therapies (SMD -0.45, 95% CI -0.82 to -0.7, P = 0.02), mindfulness (SMD -0.55, 95% CI -0.96 to -0.14, P = 0.009), hypnosis (SMD -0.88, 95% CI -1.30 to -0.46, P = 0.0001), trigger point therapies (SMD -0.83, 95% CI -1.65 to -0.01, P = 0.05) and cognitive behavioral therapy (SMD -0.64, 95% CI -1.18 to -0.11, P = 0.02). However, there is no significant effect of relaxation therapy on pain reduction in patients with MS (SMD -0.82, 95% CI -1.94 to 0.31, P = 0.15).

CONCLUSIONS

The results indicated that the majority of the non-pharmacological rehabilitation interventions showed potential therapeutic effects in reducing pain intensity in patients with MS.

Relationships between accelerometer-measured and multiple sclerosis: a 2-sample Mendelian randomization study

BACKGROUND

Observational studies suggest that physical activity (PA) can independently modify the risk of developing multiple sclerosis (MS).

OBJECTIVE

To investigate the causal effect of PA on MS by Mendelian randomization (MR) approaches.

METHODS

Through a genome-wide association study including 91,105 participants from UK Biobank, we obtained 5 single-nucleotide polymorphisms (SNPs) associated with accelerometer-measured PA (P < 5 × 10^-8). Summary-level data for MS were obtained from a meta-analysis, incorporating 14,802 subjects with MS and 26,703 healthy controls of European ancestry. MR analyses were performed using the inverse-variance-weighted method, weighted median estimator, and MR-PRESSO method. Additional analyses were further performed using MR-Egger intercept and Cochran's Q statistic to verify the robustness of our findings.

RESULTS

We failed to detect a causal effect of PA on MS (OR, 0.60; 95% confidence interval [CI], 0.30-1.20; P = 0.15) per in the random-effects IVW analysis. Additional MR methods yielded consistent results. MR-Egger regression suggested no evidence of horizontal pleiotropy (Intercept = 0.14, P = 0.21) and there seemed no substantial heterogeneity (I² = 29.8%, P = 0.22) among individual SNPs.

CONCLUSION

Our findings suggest that enhancing PA might not modify the risk of developing MS independent of established risk factors.
