Relaxation and related therapies for people with multiple sclerosis (MS): A systematic review.

OBJECTIVE: To establish the effectiveness of relaxation and related therapies in treating Multiple Sclerosis related symptoms and sequelae. DATA SOURCES: PsycINFO, PubMed, Embase, CINAHL, ProQuest Dissertations and Theses Global databases were searched. METHODS: We included studies from database inception until 31 December 2021 involving adult participants diagnosed with multiple sclerosis or disseminated sclerosis, which featured quantitative data regarding the impact of relaxation interventions on multiple sclerosis-related symptoms and sequelae. Studies which examined multi-modal therapies - relaxation delivered in combination with non-relaxation interventions - were excluded. Risk of bias was assessed using the Revised Risk of Bias tool for randomised trials - ROB2, Risk of Bias in Non-Randomised Studies of Interventions ROBINS-I), and within and between-group effects were calculated (Hedges' g). RESULTS: Twenty-eight studies met inclusion criteria. Twenty-three of these were randomised controlled trials, with 1246 total participants. This review reports on this data, with non-randomised study data reported in supplemental material. Post -intervention relaxation was associated with medium to large effect-size improvement for depression, anxiety, stress and fatigue. The effects of relaxation were superior to wait-list or no treatment control conditions; however, comparisons with established psychological or physical therapies were mixed. Individual studies reported sustained effects (≤ 6 months) with relaxation for stress, pain and quality of life. Most studies were rated as having a high/serious risk of bias. CONCLUSION: There is emerging evidence that relaxation therapies can improve outcomes for persons with multiple sclerosis. Given the high risk of bias found for included studies, stronger conclusions cannot be drawn.

Stroke survivors' expectations and post-intervention perceptions of mindfulness training: A qualitative study.

Depression and anxiety are common sequelae of stroke, occurring in at least one-third of patients. This study evaluated the acceptability and feasibility of providing mindfulness training (MT) to stroke survivors with the aim of reducing depression and anxiety. Following a six-week one-on-one MT course, 17 participants were interviewed. The median age of participants was 71, and 10 participants were male. This paper focuses on participants' expectations of the MT and their views about its impact on their everyday lives. Conventional content analysis was used for coding and analysis. A single theme, Seizing rehabilitation opportunities, was captured in relation to expectations of MT, and four themes provided information relating to participants' perceived impact of the course: Calming the mind, Reduced reactivity, Remedying physical symptoms, and Not quite there yet.Most participants knew little about mindfulness before the MT and did not have specific goals in mind when volunteering to take part. The findings suggest that most participants considered MT beneficial through reducing stress and giving them additional skills to cope with their everyday lives. A tailored mindfulness intervention may be a useful adjunct to other rehabilitation therapies for stroke survivors.

Nutritional interventions to improve neurophysiological impairments following traumatic brain injury: A systematic review.

Traumatic brain injury (TBI) accounts for significant global health burden. Effects of TBI can become chronic even following mild injury. There is a need to develop effective therapies to attenuate the damaging effects of TBI and improve recovery outcomes. This literature review using a priori criteria (PROSPERO; CRD42018100623) summarized 43 studies between January 1998 and July 2019 that investigated nutritional interventions (NUT) delivered with the objective of altering neurophysiological (NP) outcomes following TBI. Risk of bias was assessed for included studies, and NP outcomes recorded. The systematic search resulted in 43 of 3,748 identified studies met inclusion criteria. No studies evaluated the effect of a NUT on NP outcomes of TBI in humans. Biomarkers of morphological changes and apoptosis, oxidative stress, and plasticity, neurogenesis, and neurotransmission were the most evaluated NP outcomes across the 43 studies that used 2,897 animals. The risk of bias was unclear in all reviewed studies due to poorly detailed methodology sections. Taking these limitations into account, anti-oxidants, branched chain amino acids, and ω-3 polyunsaturated fatty acids have shown the most promising pre-clinical results for altering NP outcomes following TBI. Refinement of pre-clinical methodologies used to evaluate effects of interventions on secondary damage of TBI would improve the likelihood of translation to clinical populations.

Brain drawings following traumatic brain injury (TBI) and links to illness perceptions and health outcomes - Findings from a population-based study.

OBJECTIVE: Individuals' illness perceptions predict health behaviours and influence functional outcomes. This study examined associations between a novel assessment of illness perceptions, in the form of adult's brain drawings after traumatic brain injury (TBI) and questionnaire measures of illness perceptions, quality of life and post-concussive symptoms. DESIGN: Population-based, prospective longitudinal study examining 245 adults with predominantly mild TBI with high risk of complications. MAIN OUTCOME MEASURES: Participants were asked to draw pictures of what they thought their brain looked like before injury and at baseline and one month post-injury. Drawing characteristics (height, width and percentage damage at one month) were examined in relation to each outcome of interest at six months. RESULTS: Greater damage at one month was associated with more negative illness perceptions (rs = .23), poorer mental health (rs = -.21), and more total post-concussive symptoms (rs = .27 to r = .35) at six months. The extent of damage depicted reduced over time (p < .001). No associations were found between the amount of damage drawn and injury severity, nor the height or width of drawings and injury severity or illness perceptions. CONCLUSION: Drawings post-TBI offer a simple, cost- and time-effective way to begin discussions and improve understanding of peoples' illness perceptions.

Mind and body therapy for fibromyalgia.

BACKGROUND: Mind-body interventions are based on the holistic principle that mind, body and behaviour are all interconnected. Mind-body interventions incorporate strategies that are thought to improve psychological and physical well-being, aim to allow patients to take an active role in their treatment, and promote people's ability to cope. Mind-body interventions are widely used by people with fibromyalgia to help manage their symptoms and improve well-being. Examples of mind-body therapies include psychological therapies, biofeedback, mindfulness, movement therapies and relaxation strategies. OBJECTIVES: To review the benefits and harms of mind-body therapies in comparison to standard care and attention placebo control groups for adults with fibromyalgia, post-intervention and at three and six month follow-up. SEARCH METHODS: Electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), AMED (EBSCO) and CINAHL (Ovid) were conducted up to 30 October 2013. Searches of reference lists were conducted and authors in the field were contacted to identify additional relevant articles. SELECTION CRITERIA: All relevant randomised controlled trials (RCTs) of mind-body interventions for adults with fibromyalgia were included. DATA COLLECTION AND ANALYSIS: Two authors independently selected studies, extracted the data and assessed trials for low, unclear or high risk of bias. Any discrepancy was resolved through discussion and consensus. Continuous outcomes were analysed using mean difference (MD) where the same outcome measure and scoring method was used and standardised mean difference (SMD) where different outcome measures were used. For binary data standard estimation of the risk ratio (RR) and its 95% confidence interval (CI) was used. MAIN RESULTS: Seventy-four papers describing 61 trials were identified, with 4234 predominantly female participants. The nature of fibromyalgia varied from mild to severe across the study populations. Twenty-six studies were classified as having a low risk of bias for all domains assessed. The findings of mind-body therapies compared with usual care were prioritised.There is low quality evidence that in comparison to usual care controls psychological therapies have favourable effects on physical functioning (SMD -0.4, 95% CI -0.6 to -0.3, -7.5% absolute change, 2 point shift on a 0 to 100 scale), pain (SMD -0.3, 95% CI -0.5 to -0.2, -3.5% absolute change, 2 point shift on a 0 to 100 scale) and mood (SMD -0.5, 95% CI -0.6 to -0.3, -4.8% absolute change, 3 point shift on a 20 to 80 scale). There is very low quality evidence of more withdrawals in the psychological therapy group in comparison to usual care controls (RR 1.38, 95% CI 1.12 to 1.69, 6% absolute risk difference). There is lack of evidence of a difference between the number of adverse events in the psychological therapy and control groups (RR 0.38, 95% CI 0.06 to 2.50, 4% absolute risk difference).There was very low quality evidence that biofeedback in comparison to usual care controls had an effect on physical functioning (SMD -0.1, 95% CI -0.4 to 0.3, -1.2% absolute change, 1 point shift on a 0 to 100 scale), pain (SMD -2.6, 95% CI -91.3 to 86.1, -2.6% absolute change) and mood (SMD 0.1, 95% CI -0.3 to 0.5, 1.9% absolute change, less than 1 point shift on a 0 to 90 scale) post-intervention. In view of the quality of evidence we cannot be certain that biofeedback has a little or no effect on these outcomes. There was very low quality evidence that biofeedback led to more withdrawals from the study (RR 4.08, 95% CI 1.43 to 11.62, 20% absolute risk difference). No adverse events were reported.There was no advantage observed for mindfulness in comparison to usual care for physical functioning (SMD -0.3, 95% CI -0.6 to 0.1, -4.8% absolute change, 4 point shift on a scale 0 to 100), pain (SMD -0.1, CI -0.4 to 0.3, -1.3% absolute change, less than 1 point shift on a 0 to 10 scale), mood (SMD -0.2, 95% CI -0.5 to 0.0, -3.7% absolute change, 2 point shift on a 20 to 80 scale) or withdrawals (RR 1.07, 95% CI 0.67 to 1.72, 2% absolute risk difference) between the two groups post-intervention. However, the quality of the evidence was very low for pain and moderate for mood and number of withdrawals. No studies reported any adverse events.Very low quality evidence revealed that movement therapies in comparison to usual care controls improved pain (MD -2.3, CI -4.2 to -0.4, -23% absolute change) and mood (MD -9.8, 95% CI -18.5 to -1.2, -16.4% absolute change) post-intervention. There was no advantage for physical functioning (SMD -0.2, 95% CI -0.5 to 0.2, -3.4% absolute change, 2 point shift on a 0 to 100 scale), participant withdrawals (RR 1.95, 95% CI 1.13 to 3.38, 11% absolute difference) or adverse events (RR 4.62, 95% CI 0.23 to 93.92, 4% absolute risk difference) between the two groups, however rare adverse events may include worsening of pain.Low quality evidence revealed that relaxation based therapies in comparison to usual care controls showed an advantage for physical functioning (MD -8.3, 95% CI -10.1 to -6.5, -10.4% absolute change) and pain (SMD -1.0, 95% CI -1.6 to -0.5, -3.5% absolute change, 2 point shift on a 0 to 78 scale) but not for mood (SMD -4.4, CI -14.5 to 5.6, -7.4% absolute change) post-intervention. There was no difference between the groups for number of withdrawals (RR 4.40, 95% CI 0.59 to 33.07, 31% absolute risk difference) and no adverse events were reported. AUTHORS' CONCLUSIONS: Psychological interventions therapies may be effective in improving physical functioning, pain and low mood for adults with fibromyalgia in comparison to usual care controls but the quality of the evidence is low. Further research on the outcomes of therapies is needed to determine if positive effects identified post-intervention are sustained. The effectiveness of biofeedback, mindfulness, movement therapies and relaxation based therapies remains unclear as the quality of the evidence was very low or low. The small number of trials and inconsistency in the use of outcome measures across the trials restricted the analysis.
