The feasibility and impact of a yoga pilot programme on the quality-of-life of adults with acquired brain injury

Participants With Acquired Brain Injury Realized They "Could Still Do Things" After a Yoga Intervention: A Qualitative Descriptive Study

IMPORTANCE

Occupational therapy practitioners use yoga in practice to achieve holistic care, and the American Occupational Therapy Association has provided guidance on the use of yoga in occupational therapy. For people with acquired brain injury (ABI), however, it is unknown whether yoga affects occupational performance.

OBJECTIVE

To explore the perceived impact of an adapted yoga intervention on occupational performance using the Occupational Therapy Practice Framework: Domain and Process (4th ed.; OTPF-4) for participants with ABI.

DESIGN

Qualitative descriptive study using virtual, semistructured interviews. An inductive, holistic, open-coding process, followed by a deductive process to map open codes to the OTPF-4.

PARTICIPANTS

Nine individuals with ABI were recruited from a yoga intervention study.

RESULTS

The theme generated from the data-"Yoga participants with ABI realized that they could still do quite a bit"-was supported by two major categories from the OTPF-4: Occupations and Performance Skills. Participants described improvements in their functional performance (i.e., motor skills, process skills) and how these factors were synergistically connected to their occupational performance (i.e., self-care, leisure).

CONCLUSIONS AND RELEVANCE

This study provides novel insight into how functional performance improved so participants could "still do things," such as engaging in occupations. When participants described improved performance skills, they simultaneously described re-engagement with their meaningful occupations. Participants also perceived an improvement in their mind-body connection, which should be further explored in future studies. This study generated original findings about participants' perceptions of an adapted yoga intervention as they relate to the OTPF-4. Plain-Language Summary: This study reports individuals' perceptions of their re-engagement with occupations and changes in occupational performance skills after participating in an adaptive yoga intervention. We highlight the distinct contribution that adaptive yoga-an intervention modality that can be used by occupational therapy practitioners-may have, using the OTPF-4 to connect the participants' perceptions about their improvements in occupational performance.

Executive Function After Yoga: Adults With Acquired Brain Injury-A Pilot Study

IMPORTANCE

Acquired brain injury (ABI) may result in deficits in executive function (EF), which affects engagement in occupations.

OBJECTIVE

To explore the impact of group yoga on EF in people with ABI.

DESIGN

Single-arm pilot study with preyoga assessments and postyoga assessments (after 8 wk of yoga).

SETTING

Yoga classes and assessments were completed within university buildings on a college campus.

PARTICIPANTS

Twelve participants with chronic ABI (>6 mo post-ABI) were recruited through convenience and purposive strategies from the local community.

INTERVENTION

An 8-wk adaptive group yoga intervention was provided by an adaptive yoga specialist. Yoga classes were 60 min and occurred once per week.

OUTCOMES AND MEASURES

EF was assessed before and after the yoga intervention using the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) self-report form. Normative data were analyzed with paired sample t tests.

RESULTS

Nine participants completed all study procedures. Results from paired sample t tests showed significant improvements on the Behavioral Regulation Index of the BRIEF-A (p = .046). No significant improvements were found on individual EF scales, the Metacognition Index, or the Global Executive Composite (ps > .05).

CONCLUSIONS AND RELEVANCE

Group-based yoga may improve some aspects of EF for adults with chronic ABI; however, further research with larger sample sizes is needed. Plain-Language Summary: Yoga, an intervention increasingly used in occupational therapy practice, may be beneficial in improving behavioral regulation (an executive function) for adults with acquired brain injury.

Feasibility of group telerehabilitation for individuals with chronic acquired brain injury: integrating clinical care and research

BACKGROUND

Acquired brain injury (ABI) is a leading cause of lifelong disability, but access to treatment in the chronic stages has significant barriers. Group-based, remotely delivered neurorehabilitation reduces costs, travel barriers, and infection risk; however, its feasibility for patients with ABI is not well-established.

OBJECTIVES

To investigate the feasibility of remotely group-based cognitive and mood therapies for persons with chronic ABI.

METHODS

Three hundred and eighty-eight adults with chronic ABI participated in group tele-neurorehabilitation modules comprising Cognitive Behavioral Therapy, Goal Management Training®, Relaxation and Mindfulness Skills Training, and/or a novel Concussion Education & Symptom Management program. Assessments comprised quantitative metrics, surveys, as well as qualitative semi-structured interviews in a subset of participants.

RESULTS

High retention, adherence, and satisfaction were observed. Facilitators of treatment included accessibility, cost-effectiveness, and convenience. Adoption of technology was high, but other people's technological interruptions were a barrier. Self-reported benefits specific to group-based format included improved mood, stress management, coping, interpersonal relationships, cognitive functioning, and present-mindedness.

CONCLUSIONS

The present study examined chronic ABI patients' perceptions of telerehabilitation. Patients found remotely delivered, group-based mood, and cognitive interventions feasible with easy technology adoption. Group format was considered a benefit. Recommendations are provided to inform design of remotely delivered ABI programs.

The feasibility, acceptability, and effectiveness of the multimodal, community-based LoveYourBrain Retreat program for people with traumatic brain injury and caregivers

PURPOSE

To evaluate the feasibility, acceptability, and effectiveness of the LoveYourBrain Retreat program using a pre-post, retrospective, concurrent triangulation mixed methods study.

MATERIALS AND METHODS

A 5-day, multimodal, residential Retreat intervention was designed to improve quality of life among traumatic brain injury (TBI) survivors and caregivers through mindfulness, movement, nutrition, art, and community-building. Eligibility included being a TBI survivor (>2 years post-injury) or caregiver, 18+ years old, independently mobile, able to communicate verbally, and a first-time participant. Self-reported quantitative and qualitative data were collected via electronic surveys pre- and post-retreat, analyzed separately, then combined. Paired t-tests assessed mean differences in scores on Quality of Life After Brain Injury Overall scale (QOLIBRI-OS) and NIH TBI/Neuro-QOL Resilience, Cognition, Positive Affect/Wellbeing, and Emotional/Behavioral Dysregulation scales. We assessed feasibility using sample characteristics and program frequency and retention, and acceptability using quality ratings. Content analysis explored perceived benefits and improvements.

RESULTS

68 People-53 with TBI and 15 caregivers-participated in one of three LoveYourBrain Retreats. Significant improvements were found in QOLIBRI-OS (6.91, 95%CI 1.88-11.94), Resilience (2.14, 95%CI 0.50-3.78), Cognition (2.81, 95%CI 0.79-4.83), and Emotional/Behavioral Dysregulation (2.84, 95%CI 0.14-5.54) among TBI survivors (n = 41). Mean satisfaction was 9.6/10 (SD = 0.64). Content analysis revealed community connection, reframing TBI experience, self-regulation, and self-care themes.

CONCLUSIONS

The LoveYourBrain Retreat is feasible, acceptable, and may be effective complementary rehabilitation to improve QOL among TBI survivors.

Therapeutic groups run for community-dwelling people with acquired brain injury: a scoping review

PURPOSE

Therapeutic group interventions are commonly provided in acquired brain injury (ABI) inpatient rehabilitation settings, but little is known about the extent of therapeutic groups run for community-dwellers with ABI. This paper seeks to review current literature concerning the nature of therapeutic groups run for community-dwellers with ABI and the involvement of occupational therapists.

MATERIALS & METHODS

A scoping review was conducted with systematic searching of relevant databases guided by Arksey and O'Malley's framework. Studies were included if they reported on therapeutic groups for community-dwellers with ABI. Articles were collated and summarised with key findings presented in narrative form with accompanying tables.

RESULTS

Seventy articles met inclusion. Groups are used as therapeutic change agents for community-dwellers with ABI and target a diverse range of participation barriers. Participants valued group programs that established safe environments, a sense of belonging, growth opportunities and social connections. Group accessibility needs to be improved, with better funding avenues available for service providers, as well as greater consumer involvement in group design and facilitation.

CONCLUSIONS

Groups are a valuable therapeutic modality supporting community-dwellers with ABI. Further research is warranted into the use of groups by occupational therapists working with community-dwellers with ABI.IMPLICATIONS FOR REHABILITATIONTherapeutic groups can support the development of social connections, community participation and help community-dwellers with ABI re-establish a positive self-identity.Conducting groups in community settings and involving consumers in group design and facilitation may enhance the group experience for participants.Occupational Therapists should be involved in the design and delivery of occupation-based and participation focused group-based programs.

The Feasibility and Benefits of a Virtual Yoga Practice for Stroke Survivors With Aphasia

PURPOSE

The purpose of this study was to (a) examine the feasibility of a virtual, adapted, aphasia-friendly yoga program for people with aphasia; (b) evaluate evidence of improvement in patient-reported outcomes and word retrieval; (c) explore the immediate impact of a yoga session on participant subjective emotional state; and (d) assess participant motivation and perceived benefits of participating in a yoga program.

METHOD

This feasibility study employed a mixed-method design to document the feasibility of a virtual, 8-week adapted yoga program. A pre-/posttreatment design was used to assess patient-reported outcome measures for resilience, stress, sleep, and pain, as well as word-finding abilities. Semistructured interviews with participants were thematically analyzed to provide insight into participants' motivation and perceptions regarding their experience.

RESULTS

Comparisons of pre- and postprogram group means suggest that participation in an 8-week adapted yoga program may positively impact perceptions of resilience (large effect), stress (medium effect), sleep disturbance (medium effect), and pain (small effect) for people with aphasia. Findings from within-session reports and brief, semistructured interviews with participants indicated positive outcomes and subjective experiences and suggest that people with aphasia are motivated to participate in yoga for a variety of reasons.

CONCLUSIONS

This study is an important first step in confirming the feasibility of an adapted, aphasia-friendly yoga program offered via a remote platform for people with aphasia. The findings support recent work suggesting that yoga may be a potent adjunct to traditional rehabilitation efforts to improve resilience and psychosocial aspects in persons with aphasia.

LoveYourBrain Mindset: Feasibility, Acceptability, Usability, and Effectiveness of an Online Yoga, Mindfulness, and Psychoeducation Intervention for People with Traumatic Brain Injury

OBJECTIVE

Despite the benefits of yoga, mindfulness, and psychoeducation after traumatic brain injury (TBI), no online programming exists. This study investigated the feasibility, acceptability, usability, and effectiveness of the LoveYourBrain Mindset online program for people with TBI.

RESEARCH DESIGN

Pre-post, retrospective intervention.

METHODS

LoveYourBrain Mindset is a six-week online yoga, mindfulness, and psychoeducation program with weekly interactive Zoom classes and prerecorded mindfulness tools. Two interactive class types (45-minute group discussion, 75-minute group discussion and gentle yoga) are offered to enhance accessibility. People were eligible if they experienced TBI, were a caregiver, or clinician; ≥15 years old; and capable of gentle exercise and group discussion. We analyzed attendance, program ratings, mindfulness tools utilization, and pre/post-intervention differences in QOL, resilience, emotional/behavioral dysregulation, cognition, and positive affect/well-being.

RESULTS

Overall, 1539 individuals signed up for LoveYourBrain Mindset with 1093 (71.02%) participating in one/more classes. The mean program rating was 9.09 (SD=1.28). Majority (62.99%) used the mindfulness tools each week. Multiple linear regression models controlling for age, TBI severity, and gender indicated significant improvements in QOL, resilience, emotional/behavioral dysregulation, cognition, and positive affect/well-being (p<0.001).

CONCLUSION

LoveYourBrain Mindset is feasible, acceptable, usable, and may improve outcomes among people with TBI.

Astragaloside IV Alleviates Brain Injury Induced by Hypoxia via the Calpain-1 Signaling Pathway

Long-term hypoxia can induce oxidative stress and apoptosis in hippocampal neurons that can lead to brain injury diseases. Astragaloside IV (AS-IV) is widely used in the antiapoptotic therapy of brain injury diseases. However, its mechanism of action is still not fully understood. In this study, we investigated the effect of AS-IV on hypoxia-induced oxidative stress and apoptosis in hippocampal neurons and explored its possible mechanism. In vivo, mice were placed in a hypoxic circulatory device containing 10% O₂ and gavaged with AS-IV (60 and 120 mg/kg/d) for 4 weeks. In vitro, mouse hippocampal neuronal cells (HT22) were treated with hypoxia (1% O₂) for 24 hours in the presence or absence of AS-IV, MDL-28170 (calpain-1 inhibitor), or YC-1 (HIF-1α inhibitor). The protective effect of AS-IV on brain injury was further explored by examining calpain-1 knockout mice. The results showed that hypoxia induced damage to hippocampal neurons, impaired spatial learning and memory abilities, and increased oxidative stress and apoptosis. Treatment with AS-IV or calpain-1 knockout improved the damage to hippocampal neurons and spatial learning and memory, attenuated oxidative stress and inhibited cell apoptosis. These changes were verified in HT22 cells. Overexpression of calpain-1 abolished the improvement of AS-IV on apoptosis and oxidative stress. In addition, the effects of AS-IV were accompanied by decreased calpain-1 and HIF-1α expression, and YC-1 showed a similar effect as AS-IV on calpain-1 and caspase-3 expression. In conclusion, this study demonstrates that AS-IV can downregulate the calpain-1/HIF-1α/caspase-3 pathway and inhibit oxidative stress and apoptosis of hippocampal neurons induced by hypoxia, which provides new ideas for studying the antiapoptotic activity of AS-IV.

Community-Based Interventions After Acquired Brain Injury-A Systematic Review of Intervention Types and Their Effectiveness

OBJECTIVES

Comprehensive review of existing types and effectiveness of community-based interventions delivered to adults (mean age 18-65 years) with long-lasting (≥6 months) difficulties following acquired brain injury (ABI).

DESIGN

Systematic review of controlled intervention studies published until February 2021.

MAIN MEASURES

Systematic searches in databases (MEDLINE, PsycINFO, Database of Abstracts of Reviews of Effects [Cochrane Library], and Cochrane Central Register of Controlled Trials [Cochrane Library]) and inclusion of English peer-reviewed full-text articles; randomized or controlled community-based intervention studies; sample size of 20 or more participants; and 3 or more intervention sessions. Two reviewers independently extracted data for the synthesis and assessed the methodological quality. Data extraction included study characteristics, demographics of participants, content and dose of intervention, outcome measures, and findings.

RESULT

The search returned 7386 publications, of which 49 eligible studies were included, revealing a diverse range of community-based interventions and a myriad of outcome measures applied for assessing functional capacities, participation, and quality of life in the chronic phase of ABI. Intervention types encompassed 14 holistic, 23 physical, and 12 specific interventions. A large heterogeneity regarding intervention frequency and intensity was found. Meta-analyses performed on the holistic, physical, and specific interventions did not indicate any significant pooled effects but showed highly variable effects between individuals, both in persons with traumatic and nontraumatic brain injuries.

CONCLUSIONS

Because of lack of pooled effects within types of community-based interventions, specific evidence-based recommendations within holistic, physical, and specific interventions designed to mitigate long-lasting ABI problems cannot be made. This review highlights the need for future studies to address methodological issues concerning larger sample size, lack of clear description interventions and comparator, missing reports of effects in change scores, need for consistent use of recommended outcome measures, and investigating the wide variety in intervention responsiveness among participants with ABI. Systematic review registration: PROSPERO (CRD42019124949).

Self-Regulation and Relaxation-Based Interventions for Adults With Traumatic Brain Injury (2013-2020)

Systematic Review Briefs provide a summary of the findings from systematic reviews developed in conjunction with the American Occupational Therapy Association's Evidence-Based Practice Program. Each Systematic Review Brief summarizes the evidence on a theme related to a systematic review topic. This Systematic Review Brief presents findings from the systematic review on self-regulation and relaxation-based interventions to improve psychosocial outcomes for people with traumatic brain injury.

"Hidden gains"? Measuring the impact of mindfulness-based interventions for people with mild traumatic brain injury: a scoping review

BACKGROUND

Mindfulness-based interventions can support recovery from mild traumatic brain injury (mTBI). Although measurement is a key determinant of outcomes, there is no comprehensive assessment of measurement approaches used to capture outcomes of these programs. Here, we review the domains targeted, measurement techniques used, and domains and techniques most affected by mindfulness-based interventions for mTBI.

METHODS

We conducted a scoping review. After screening and full-text review, we included 29 articles and extracted data related to measurement domains, techniques, and results.

RESULTS

We identified 8 outcome domains, each with multiple subdomains. The most common domains were cognitive symptoms and general health/quality of life. No quantitative studies directly assessed sleep, physical-function, or pain-catastrophizing. Self-report was the most common measurement technique, followed by performance-based methods. Coping, somatic symptoms, emotional symptoms, stress response, and domains of cognition (particularly attention) were the most frequently improved domains. Qualitative results described benefits across all domains and suggested novel areas of benefit. Biomarkers did not reflect significant change.

CONCLUSIONS

Mindfulness-based interventions for mTBI impact a range of clinical domains and are best captured with a combination of measurement approaches. Using qualitative methods and expanding the breadth of outcomes may help capture underexplored effects of mindfulness-based interventions for mTBI.

A crossover pilot trial of the feasibility, acceptability, and effectiveness of LoveYourBrain Yoga for community-dwelling adults with multiple sclerosis

BACKGROUND AND PURPOSE

Among people with multiple sclerosis (MS), yoga has potential to improve fatigue and other symptoms that undermine quality of life. The aim of this study was to assess the feasibility, acceptability, and effectiveness of LoveYourBrain Yoga, a six-week yoga with psychoeducation program, on fatigue and other health-related outcomes among people with MS in a rural, community-based setting in the United States.

METHODS

This non-randomized 2x2 crossover pilot trial compared LoveYourBrain Yoga to a control among 15 people with MS. People were eligible if they were adults with MS (EDSS score ≤6), English-speaking, and ambulatory. Paired t-tests and Wilcoxon signed rank sum analyses assessed mean differences in PROMIS-Fatigue_MS, Multiple Sclerosis Impact Scale, Symbol Digit Modalities Test, NIH Neuro-QoL measures, and Liverpool Self-Efficacy scale. We assessed feasibility using recruitment and retention rates, mean attendance, fidelity, and acceptability using satisfaction measures.

RESULTS

Significant improvements in fatigue (MD -4.34, SD 5.26, p = 0.012), positive affect and wellbeing (MD 2.76, SD 3.99, p = 0.028), and anxiety (MD -4.42, SD 5.36, p = 0.012) were found after LoveYourBrain Yoga compared to the control. Participants reported high satisfaction (M 9.5, SD 1.4) and a majority (92.3%) reported 'Definitely, yes' to recommending it to a friend or family.

CONCLUSION

LoveYourBrain Yoga is feasible and acceptable when implemented in a rural, community-based setting for people with MS. It may improve a range of MS symptoms and offer a means for acquiring new skills for stress reduction, anxiety management, and overall wellbeing.

Feasibility of a Combined Neuromodulation and Yoga Intervention for Mild Traumatic Brain Injury and Chronic Pain: Protocol for an Open-label Pilot Trial

BACKGROUND

Mild traumatic brain injury (mTBI) and chronic pain often co-occur and worsen rehabilitation outcomes. There is a need for improved multimodal nonpharmacologic treatments that could improve outcomes for both conditions. Yoga is a promising activity-based intervention for mTBI and chronic pain, and neuromodulation through transcranial magnetic stimulation is a promising noninvasive, nonpharmacological treatment for mTBI and chronic pain. Intermittent theta burst stimulation (iTBS) is a type of patterned, excitatory transcranial magnetic stimulation. iTBS can induce a window of neuroplasticity, making it ideally suited to boost the effects of treatments provided after it. Thus, iTBS may magnify the impacts of subsequently delivered interventions as compared to delivering those interventions alone and accordingly boost their impact on outcomes.

OBJECTIVE

The aim of this study is to (1) develop a combined iTBS+yoga intervention for mTBI and chronic pain, (2) assess the intervention's feasibility and acceptability, and (3) gather preliminary clinical outcome data on quality of life, function, and pain that will guide future studies.

METHODS

This is a mixed methods, pilot, open-labeled, within-subject intervention study. We will enroll 20 US military veteran participants. The combined iTBS+yoga intervention will be provided in small group settings once a week for 6 weeks. The yoga intervention will follow the LoveYourBrain yoga protocol-specifically developed for individuals with TBI. iTBS will be administered immediately prior to the LoveYourBrain yoga session. We will collect preliminary quantitative outcome data before and after the intervention related to quality of life (TBI-quality of life), function (Mayo-Portland Adaptability Index), and pain (Brief Pain Inventory) to inform larger studies. We will collect qualitative data via semistructured interviews focused on intervention acceptability after completion of the intervention.

RESULTS

This study protocol was approved by Edward Hines Jr Veterans Administration Hospital Institutional Review Board (Hines IRB 1573116-4) and was prospectively registered on ClinicalTrials.gov (NCT04517604). This study includes a Food and Drug Administration Investigational Device Exemption (IDE: G200195). A 2-year research plan timeline was developed. As of March 2022, a total of 6 veterans have enrolled in the study. Data collection is ongoing and will be completed by November 2022. We expect the results of this study to be available by October 2024.

CONCLUSIONS

We will be able to provide preliminary evidence of safety, feasibility, and acceptability of a novel combined iTBS and yoga intervention for mTBI and chronic pain-conditions with unmet treatment needs.

Characteristics, Outcomes, Sex and Gender Considerations of Community-Based Physical Activity Interventions after Moderate-to-Severe Traumatic Brain Injury: Scoping Review

OBJECTIVE

This scoping review mapped the current evidence about community-based physical activity (PA) interventions for individuals with moderate-to-severe traumatic brain injury (TBI) and identified the reported health-related outcomes, measurement tools used, and considerations given to sex and gender.

METHODS

Searches were conducted in six academic databases for peer-reviewed articles (MEDLINE, EMBASE, Cochrane CENTRAL, CINAHL, SPORTDiscus, and PEDro). PRISMA Scoping Review guidelines were followed. Two reviewers independently screened articles for inclusion and extracted data for the analysis with a modified Consensus on Exercise Reporting Template (CERT). Health-related outcomes were classified with domains of the International Classification of Function, Disability and Health (ICF).

RESULTS

19 studies were identified. Seven PA intervention types were included. CERT scores varied (M = 12.74, SD = 3.51 items), with limited details for replication. ICF outcomes focused on improving body functions (74%), activities and participation (14%), environmental factors (1%), and other: not covered (11%). Only four studies (21%) stratified their results by sex or gender.

CONCLUSIONS

Identified PA interventions from this review revealed common characteristics that led to improved outcomes. Proposed recommendations aim to improve future research and community practice. There is a pressing need for more sex and gender considerations in PA research after moderate-to-severe TBI.

Occupational therapy for cognitive impairment in stroke patients

BACKGROUND

Cognitive impairment is a frequent consequence of stroke and can impact on a person's ability to perform everyday activities. Occupational therapists use a range of interventions when working with people who have cognitive impairment poststroke. This is an update of a Cochrane Review published in 2010.

OBJECTIVES

To assess the impact of occupational therapy on activities of daily living (ADL), both basic and instrumental, global cognitive function, and specific cognitive abilities in people who have cognitive impairment following a stroke.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, Embase, four other databases (all last searched September 2020), trial registries, and reference lists.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that evaluated an intervention for adults with clinically defined stroke and confirmed cognitive impairment. The intervention needed either to be provided by an occupational therapist or considered within the scope of occupational therapy practice as defined in the review. We excluded studies focusing on apraxia or perceptual impairments or virtual reality interventions as these are covered by other Cochrane Reviews. The primary outcome was basic activities of daily living (BADL) such as dressing, feeding, and bathing. Secondary outcomes were instrumental ADL (IADL) (e.g. shopping and meal preparation), community integration and participation, global cognitive function and specific cognitive abilities (including attention, memory, executive function, or a combination of these), and subdomains of these abilities. We included both observed and self-reported outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies that met the inclusion criteria, extracted data, and assessed the certainty of the evidence. A third review author moderated disagreements if consensus was not reached. We contacted trial authors for additional information and data, where available. We assessed the certainty of key outcomes using GRADE.  MAIN RESULTS: We included 24 trials from 11 countries involving 1142 (analysed) participants (two weeks to eight years since stroke onset). This update includes 23 new trials in addition to the one study included in the previous version. Most were parallel randomised controlled trials except for one cross-over trial and one with a two-by-two factorial design. Most studies had sample sizes under 50 participants. Twenty studies involved a remediation approach to cognitive rehabilitation, particularly using computer-based interventions. The other four involved a compensatory and adaptive approach. The length of interventions ranged from 10 days to 18 weeks, with a mean total length of 19 hours. Control groups mostly received usual rehabilitation or occupational therapy care, with a few receiving an attention control that was comparable to usual care; two had no intervention (i.e. a waiting list). Apart from high risk of performance bias for all but one of the studies, the risk of bias for other aspects was mostly low or unclear.  For the primary outcome of BADL, meta-analysis found a small effect on completion of the intervention with a mean difference (MD) of 2.26 on the Functional Independence Measure (FIM) (95% confidence interval (CI) 0.17 to 4.22; P = 0.03, I2 = 0%; 6 studies, 336 participants; low-certainty evidence). Therefore, on average, BADL improved by 2.26 points on the FIM that ranges from 18 (total assist) to 126 (complete independence). On follow-up, there was insufficient evidence of an effect at three months (MD 10.00, 95% CI -0.54 to 20.55; P = 0.06, I2 = 53%; 2 studies, 73 participants; low-certainty evidence), but evidence of an effect at six months (MD 11.38, 95% CI 1.62 to 21.14, I2 = 12%; 2 studies, 73 participants; low-certainty evidence). These differences are below 22 points which is the established minimal clinically important difference (MCID) for the FIM for people with stroke. For IADL, the evidence is very uncertain about an effect (standardised mean difference (SMD) 0.94, 95% CI 0.41 to 1.47; P = 0.0005, I2 = 98%; 2 studies, 88 participants). For community integration, we found insufficient evidence of an effect (SMD 0.09, 95% CI -0.35 to 0.54; P = 0.68, I2 = 0%; 2 studies, 78 participants). There was an improvement of clinical importance in global cognitive functional performance after the intervention (SMD 0.35, 95% CI 0.16 to 0.54; P = 0.0004, I2 = 0%; 9 studies, 432 participants; low-certainty evidence), equating to 1.63 points on the Montreal Cognitive Assessment (MoCA) (95% CI 0.75 to 2.52), which exceeds the anchor-based MCID of the MoCA for stroke rehabilitation patients of 1.22. We found some effect for attention overall (SMD -0.31, 95% CI -0.47 to -0.15; P = 0.0002, I2 = 20%; 13 studies, 620 participants; low-certainty evidence), equating to a difference of 17.31 seconds (95% CI 8.38 to 26.24), and for executive functional performance overall (SMD 0.49, 95% CI 0.31 to 0.66; P < 0.00001, I2 = 74%; 11 studies, 550 participants; very low-certainty evidence), equating to 1.41 points on the Frontal Assessment Battery (range: 0-18). Of the cognitive subdomains, we found evidence of effect of possible clinical importance, immediately after intervention, for sustained visual attention (moderate certainty) equating to 15.63 seconds, for working memory (low certainty) equating to 59.9 seconds, and thinking flexibly (low certainty), compared to control.

AUTHORS' CONCLUSIONS

The effectiveness of occupational therapy for cognitive impairment poststroke remains unclear. Occupational therapy may result in little to no clinical difference in BADL immediately after intervention and at three and six months' follow-up. Occupational therapy may slightly improve global cognitive performance of a clinically important difference immediately after intervention, likely improves sustained visual attention slightly, and may slightly increase working memory and flexible thinking after intervention. There is evidence of low or very low certainty or insufficient evidence for effect on other cognitive domains, IADL, and community integration and participation.  Given the low certainty of much of the evidence in our review, more research is needed to support or refute the effectiveness of occupational therapy for cognitive impairment after stroke. Future trials need improved methodology to address issues including risk of bias and to better report the outcome measures and interventions used.

Therapeutic Effects of Meditation, Yoga, and Mindfulness-Based Interventions for Chronic Symptoms of Mild Traumatic Brain Injury: A Systematic Review and Meta-Analysis

BACKGROUND

Chronic symptoms of mild traumatic brain injury (mTBI) vary greatly and are difficult to treat; we investigate the impact of meditation, yoga, and mindfulness-based interventions on this treatment group.

METHOD

Search included four databases, allowing studies of any design containing pre/post outcomes for meditation, yoga, or mindfulness-based interventions in people suffering from brain injury acquired by mechanical force. Analyses used robust variance estimation to assess overall effects and random-effects models for selected outcomes; we evaluated both between- and within-group changes.

RESULTS

Twenty studies (N = 539) were included. Results revealed significant improvement of overall symptoms compared to controls (d = 0.41; 95% CI [0.04, 0.77]; τ²  = 0.06), with significant within-group improvements in mental health (d = 0.39), physical health (d = 0.39), cognitive performance (d = 0.24), quality of life (d = 0.39), and self-related processing (d = 0.38). Symptoms showing greatest improvement were fatigue (d = 0.96) and depression (d = 0.40). Findings were homogeneous across studies. Study quality concerns include lack of randomisation, blinding, and recording of adverse events.

CONCLUSIONS

This first-ever meta-analysis on meditation, yoga, and mindfulness-based interventions for chronic symptoms of mTBI offers hope but highlights the need for rigorous new trials to advance clinical applications and to explore mechanistic pathways.

The impact of a yoga-based physical therapy group for individuals with traumatic brain injury: results from a pilot study

OBJECTIVE

To compare the impacts of yoga-based physical therapy versus a seated rest within the context of standard rehabilitation practice on sleep, heart rate variability (HRV), anxiety, and fatigue during acute traumatic brain injury (TBI) rehabilitation.

METHODS

Eleven individuals participated in this crossover study involving the following interventions in a randomized order: group yoga-based physical therapy (YPT), conventional physical therapy (CPT), and group seated rest in a relaxing environment (SR). HRV and self-reported anxiety and fatigue were measured immediately before and after each group, and sleep after each condition and at baseline. Data was analyzed using generalized linear mixed models with repeated measures.

RESULTS

The interaction between time and treatment was statistically significant (p = .0203). For the SR treatment, wake after sleep onset (WASO) rate was reduced from 14.99 to 10.60 (IRR = 0.71; p = .006). Time and treatment were not found to be statistically significantly associated with any of the secondary outcomes.

CONCLUSION

Yoga-based physical therapy is feasible and safe in the inpatient rehabilitation setting following TBI. Sleep quality improved following the addition of a one-hour seated rest in a relaxing environment to a standard rehabilitation daily schedule, suggesting that structured rest time may be beneficial to sleep hygiene during inpatient rehabilitation following TBI.

Yoga improves balance, mobility, and perceived occupational performance in adults with chronic brain injury: A preliminary investigation

BACKGROUND AND PURPOSE

This was a preliminary investigation to investigate potential benefits of group yoga, as past work has indicated that one-on-one yoga can improve functional deficits in adults with brain injury.

MATERIALS AND METHODS

Participants served as their own controls. Nine participants with chronic brain injury were recruited, and seven (four female) completed the study. Performance measures of balance and mobility and self-reported measures of balance confidence, pain, and occupational performance and satisfaction were used. Data were collected 3 times: baseline (study onset), pre-yoga (after an 8-week no-contact period), and post-yoga (after 8 weeks of yoga). Group yoga was led by a yoga instructor/occupational therapist, and sessions lasted 1 h and occurred twice a week.

RESULTS

No participants withdrew due to adverse effects from yoga. There were no significant changes between baseline and pre-yoga. Significant improvement was observed post-yoga in balance (p = 0.05), mobility (p = 0.03), and self-reported occupational performance (p = 0.04).

CONCLUSION

We observed significant improvements in balance, mobility, and self-reported occupational performance in adults with chronic brain injury.

The Lived Experience and Patient-reported Benefits of Yoga Participation in an Inpatient Brain Injury Rehabilitation Setting

CONTEXT

The multifactorial benefits of yoga have been well documented in the literature, with the integration of yoga therapy into healthcare being an emerging field. In general, yoga therapy programs are utilized in the community as an adjunct to other therapy. At present, limited rehabilitation units routinely incorporate integrative therapy options within a hospital environment.

AIMS

The aim of this study is to explore the lived experience and patient-reported benefits of yoga in an inpatient brain injury rehabilitation setting.

SETTINGS AND DESIGN

Thirty-one participants were recruited to the study after voluntarily participating in a yoga class within an inpatient brain injury rehabilitation unit of a major metropolitan hospital. Yoga sessions were held weekly for 60 min and consisted of a modified Hatha yoga style. This was a mixed-methods, quasi-experimental one-group pretest-posttest study.

METHODOLOGY

Quantitative data were collected to measure perceptions of relaxation and well-being before and after yoga classes, along with the satisfaction of the class. Semi-structured interviews were utilized to collect qualitative data of experiences and perceptions associated with yoga participation.

STATISTICAL ANALYSIS USED

Thematic analysis was completed for qualitative data. Quantitative data were analyzed using nonparametric statistical methods, and descriptive statistics were also provided.

RESULTS

The benefits described by participants are reported in this paper. These include improved relaxation, physical well-being, emotional well-being, being present, and self-awareness.

CONCLUSIONS

This study describes the personal benefits experienced from regular yoga participation within an inpatient rehabilitation setting.

A retrospective study on the acceptability, feasibility, and effectiveness of LoveYourBrain Yoga for people with traumatic brain injury and caregivers

PURPOSE

To conduct a mixed methods, pre-post, retrospective study on the feasibility, acceptability, and effectiveness of the LoveYourBrain Yoga program.

MATERIALS AND METHODS

People were eligible if they were a traumatic brain injury survivor or caregiver, age 15-70, ambulatory, and capable of gentle exercise and group discussion. We analyzed attendance, satisfaction, and mean differences in scores on Quality of Life After Brain Injury Overall scale (QOLIBRI-OS) and four TBI-QOL/Neuro-QOL scales. Content analysis explored perceptions of benefits and areas of improvement.

RESULTS

1563 people (82.0%) participated ≥1 class in 156 programs across 18 states and 3 Canadian provinces. Mean satisfaction was 9.3 out of 10 (SD 1.0). Mixed effects linear regression found significant improvements in QOLIBRI-OS (B 9.70, 95% CI: 8.51, 10.90), Resilience (B 1.30, 95% CI: 0.60, 2.06), Positive Affect and Well-being (B 1.49, 95% CI: 1.14, 1.84), and Cognition (B 1.48, 95% CI: 0.78, 2.18) among traumatic brain injury survivors (n = 705). No improvement was found in Emotional and Behavioral Dysregulation, however, content analysis revealed better ability to regulate anxiety, anger, stress, and impulsivity. Caregivers perceived improvements in physical and psychological health.

CONCLUSIONS

LoveYourBrain Yoga is feasible and acceptable and may be an effective mode of community-based rehabilitation.IMPLICATIONS FOR REHABILITATIONPeople with traumatic brain injury and their caregivers often experience poor quality of life and difficulty accessing community-based rehabilitation services.Yoga is a holistic, mind-body therapy with many benefits to quality of life, yet is largely inaccessible to people affected by traumatic brain injury in community settings.Participants in LoveYourBrain Yoga, a six-session, community-based yoga with psychoeducation program in 18 states and 3 Canadian provinces, experienced significant improvements in quality of life, resilience, cognition, and positive affect.LoveYourBrain Yoga is feasible and acceptable when implemented on a large scale and may be an effective mode of, or adjunct to, community-based rehabilitation.

A qualitative study of LoveYourBrain Yoga: a group-based yoga with psychoeducation intervention to facilitate community integration for people with traumatic brain injury and their caregivers

Purpose: To explore participants' experiences in a group-based yoga with psychoeducation intervention designed to facilitate community integration for people with traumatic brain injury and their caregivers.Materials and methods: We conducted semi-structured interviews with 13 people with traumatic brain injury and three caregivers who had completed LoveYourBrain Yoga, a 6-session, manualized, group-based yoga intervention that incorporates breathing exercises, yoga, meditation, and psychoeducation. Interviews were analyzed using content analysis.Results: We identified seven themes: ease of participation, belonging, sustaining community connection, physical health, self-regulation, self-efficacy, and resilience. All participants valued the community-based yoga studio environment and multifaceted structure of the program. Participants reported improvements in strength, balance, flexibility, and attention control, and a greater sense of belonging, community connection, and ability to move forward with their lives. Participants reported ongoing use of tools (e.g., breathing exercises) to cope with negative emotions and stress. About half of participants sustained relationships built during LoveYourBrain Yoga and felt more capable of accessing other activities in their community.Conclusions: LoveYourBrain Yoga successfully promoted community integration for people with traumatic brain injury. It also facilitated diverse and meaningful physical, psychological, and social health benefits, which suggest that it may be an effective mode of community-based rehabilitation.Implications for rehabilitationTraumatic brain injury survivors often struggle to participate in their community, the ultimate goal of rehabilitationYoga is a holistic therapy with many benefits, yet is not accessible to the traumatic brain injury population at the community levelParticipants in a community-based yoga with psychoeducation intervention in six states experienced diverse and meaningful physical, psychological, and social health benefitsGroup-based yoga with psychoeducation may be an effective mode of community integration and community-based rehabilitation for traumatic brain injury survivors.
