A Review of Yoga and Meditation Neuroimaging Studies in Healthy Subjects

Naturalistic Evaluation of an Adjunctive Yoga Program for Women with Substance Use Disorders in Inpatient Treatment: Within-Treatment Effects on Cravings, Self-efficacy, Psychiatric Symptoms, Impulsivity, and Mindfulness

Addiction continues to be a major public health concern, and rates of relapse following currently-available treatments remain high. There is increasing interest in the adjunctive use of mindfulness-based interventions, such as yoga, to improve treatment outcomes. The current study was a preliminary naturalistic investigation of a novel trauma-informed yoga intervention in an inpatient treatment program for women with substance use disorder (SUD). Changes and differences in somatic symptoms, psychiatric symptoms, and psychological mechanisms were evaluated in women receiving treatment-as-usual (n = 36) and treatment-as-usual plus the yoga intervention (n = 42). For both groups, statistically significant within-subjects changes were present for somatic and psychiatric symptoms, cravings, self-efficacy, and multiple facets of impulsivity and mindfulness. Compared to standard treatment alone, participants in the treatment plus yoga condition significantly improved in range of motion and the Lack of Premeditation facet of impulsivity. Although most domains were not selectively affected, these initial within-treatment findings in this naturalistic evaluation suggest some promise for adjunctive yoga and a need for further evaluation, especially using larger samples and longer term follow-up.

Psychosis or spiritual emergency? A Foucauldian discourse analysis of case reports of extreme mental states in the context of meditation

Meditation is becoming increasingly popular in the West and research on its effects is growing. While studies point to various benefits of meditation on mental and physical health, reports of extreme mental states in the context of meditation have also been published. This study employed Foucauldian discourse analysis to examine how the experience of extreme mental states has been constructed in case reports and what kind of practices were employed to address them. The study analyses how extreme mental states associated with meditation are framed within the scientific literature and how such differential framings may affect the meaning making and help-seeking of persons experiencing these states. A systematic scientific literature search identified 22 case studies of extreme mental states experienced by practitioners of various types of meditation. The analysis suggests a discursive divide between two dominant framings: a biomedical discourse which constructs such experiences as psychiatric symptoms and an alternative discursive, which understands them as spiritual emergencies. Both approaches offered distinct therapeutic avenues. This divide maps onto the disciplinary divides within the mental health field more generally, which may obscure a better understanding of these experiences. However, the two discourses are not necessarily mutually exclusive and authors of three articles chose to blend them for their case reports. A supportive environment could help those experiencing extreme state integrate them into their lives. Our findings encourage collaboration between clinicians, therapists and spiritual teachers in order to make a range of approaches available.

Effect of mindfulness yoga programme MiYoga on attention, behaviour, and physical outcomes in cerebral palsy: a randomized controlled trial

AIM

To investigate the efficacy of an embodied mindfulness-based movement programme (MiYoga), targeting attention in children with cerebral palsy (CP).

METHOD

Total number of participants 42, with 24 boys (57.1%) and 18 girls (42.9%); mean age 9y 1mo, SD 3y; Gross Motor Function Classification System levels I=22, II=12, III=8) and their parents were randomized to either MiYoga (n=21) or waitlist comparison (n=21) groups. The primary outcome was attention postintervention measured by the Conners' Continuous Performance Test, Second Edition (CCPT). Secondary outcomes included parent and child mindfulness, child quality of life, parental well-being, child executive function, child behaviour, child physical measures, and the parent-child relationship.

RESULTS

Children in the MiYoga group demonstrated significantly better attention postintervention than the waitlist comparison group, with lower inattention scores on the hit reaction time standard error (F_1,33 =4.59, p=0.04, partial eta-squared [ηp2]=0.13) variable and fewer perseveration errors (F_1,33 =4.60, p=0.04, ηp2=0.13) on the CCPT. Intention-to-treat analysis also revealed that sustained attention in the MiYoga group was significantly better than in the waitlist comparison group postintervention (F_1,37 =5.97, p=0.02, ηp2=0.14). Parents in the MiYoga group demonstrated significantly decreased mindfulness (Mindfulness Attention Awareness Scale; F_1,33 =10.130, p=0.003, ηp2=0.246).

INTERPRETATION

MiYoga offers a lifestyle intervention that improves attention in children with CP. MiYoga can be considered as an additional option to standard rehabilitation to enhance attention for children with CP.

WHAT THIS PAPER ADDS

MiYoga, an embodied mindfulness-based movement programme, can enhance attention (more attentive and consistent performance) in children with cerebral palsy. MiYoga had no significant effect on physical functioning.

Yoga and substance use disorders: A narrative review

Yoga has been utilized for promotion of health and alleviating distress. It has also been used as a therapeutic measure in the field of mental health, including substance use disorders. This narrative review discusses the literature pertaining to use of yoga in the treatment of substance use disorders. The evidence base especially with regards to randomized trials is presented. The possible mechanisms how yoga might be helpful in the treatment of substance use disorders are explored. Subsequently, implications of yoga in clinical practice are elaborated, followed by examination of the issues in interpretation of the literature of published yoga related studies.
