Yoga and mental health: A dialogue between ancient wisdom and modern psychology.

BACKGROUND: Many yoga texts make reference to the importance of mental health and the use of specific techniques in the treatment of mental disorders. Different concepts utilized in modern psychology may not come with contemporary ideas, instead, they seem to share a common root with ancient wisdom. AIMS: The goal of this perspective article is to correlate modern techniques used in psychology and psychiatry with yogic practices, in the treatment of mental disorders. MATERIALS AND METHODS: The current article presented a dialogue between the yogic approach for the treatment of mental disorder and concepts used in modern psychology, such as meta-cognition, disidentification, deconditioning and interoceptive exposure. CONCLUSIONS: Contemplative research found out that modern interventions in psychology might not come from modern concepts after all, but share great similarity with ancient yogic knowledge, giving us the opportunity to integrate the psychological wisdom of both East and West.

Reducing the symptomatology of panic disorder: the effects of a yoga program alone and in combination with cognitive-behavioral therapy.

INTRODUCTION: Yoga is a holistic system of different mind-body practices that can be used to improve mental and physical health. It has been shown to reduce perceived stress and anxiety as well as improve mood and quality of life. Research documenting the therapeutic benefits of yoga has grown progressively for the past decades and now includes controlled trials on a variety of mental health conditions such as depression, anxiety, and panic disorder. OBJECTIVES: The primary goal of this study was to investigate the effects of yoga in patients suffering from panic disorder. We aimed at observing the efficacy of yoga techniques on reducing the symptomatology of panic disorder (anxiety and agoraphobia), compared to a combined intervention of yoga and psychotherapy. METHOD: Twenty subjects previously diagnosed with panic disorder were selected. Subjects were randomly assigned to both experimental groups: Group 1 (G1-Yoga: 10 subjects) attended yoga classes and Group 2 (G2-CBT + Yoga: 10 subjects) participated in a combined intervention of yoga practice followed by a cognitive-behavioral therapy (CBT) session. Both interventions occurred weekly for 100 min and lasted 2 months. Subjects were evaluated two times during the study: pre-test and post-test. Psychometric tools included the Beck Anxiety Inventory (BAI), Hamilton Anxiety Rating Scale (HAM-A), The Panic Beliefs Inventory (PBI), and Body Sensations Questionnaire (BSQ). RESULTS: Statistical analysis showed significant reductions in anxiety levels associated with panic disorder (G1: BAI - p = 0.035, HAM-A - p = 0.000; G2: BAI - p = 0.002, HAM-A - p = 0.000), panic-related beliefs (G1: PBI - p = 0.000; G2: PBI - p = 0.000) and panic-related body sensations (G1: BSQ - p = 0.000; G2: BSQ - p = 0.000) both in G1 and G2. However, the combination of yoga and CBT (G2) showed even further reductions in all observed parameters (mean values). CONCLUSION: This study observed significant improvement in panic symptomatology following both the practice of yoga and the combination of yoga and psychotherapy. While contemplative techniques such as yoga promote a general change in dealing with private events, CBT teaches how to modify irrational beliefs and specific cognitive distortions. The results observed in G2 might indicate that the techniques complemented each other, increasing the intervention efficacy. These findings are in agreement with many investigations found in the literature which observed improvements in different mental health parameters after the practice of contemplative techniques alone or combined to psychotherapy. Future research joining psychological and physiological variables could help better elucidate the mechanisms through which mind-body practices work to improve mental health.

Os benefícios do yoga nos transtornos de ansiedade / Benefits of yoga practices for anxiety disorders

Nos últimos anos, estudos têm mostrado que um grande número de pessoas experimentará algum tipo de transtorno de ansiedade de maneira contínua ou recorrente. Terapias complementares como o yoga vêm provando sua eficácia significativa na redução dos sintomas de ansiedade. Portanto, o objetivo deste estudo é discutir o uso de yoga como intervenção para o tratamento de transtornos de ansiedade com base nos resultados de grandes estudos controlados. Esta análise concluiu que o yoga parece ser uma intervenção consistente, bem-sucedida e com boa relação custo-benefício no tratamento dos transtornos de ansiedade. No entanto, este é um novo campo de pesquisa e novas investigações combinando variáveis psicológicas e fisiológicas são necessárias para estabelecer um protocolo de yoga como intervenção principal ou complementar no tratamento da ansiedade

Over the last years, studies have shown that a great number of individuals will experience some kind of anxiety disorder on a continuing or recurring basis. Complementary therapies such as yoga have been proved to significantly reduce anxiety symptoms. Therefore, the goal of this study was to discuss the use of yoga as an intervention for treating anxiety disorders based on findings from major controlled studies. This analysis has concluded that yoga seems to be a consistent, cost-effective and successful health care intervention in the treatment of anxiety disorders. However, this is a new field of research and further investigations combining psychological and physiological variables are necessary to establish yoga as a main or complementary protocol in the treatment of anxiety

Changes in cortical relative power in patients submitted to a tendon transfer: a pre and post surgery study.

The aim of this study is analyze possible modifications in the cerebral cortex, through quantitative electroencephalography (qEEG) in patients submitted to a tendon transfer procedure (posterior tibialis) by the Srinivasan's technique. Four subjects (2 men and 2 women), 49.25 age average (SD +/ 21.4) were studied. All subjects have been through surgical procedure due to leprosy and had, at least, two years of drop foot condition. The qEEG measured the electrocortical activity (relative power) between 8 and 25 Hz frequencies pre and post surgery. A paired t test analyzed all data (p< or =0,05). The results show significant alterations in the alpha relative power, electrodes F7 (p=0.01) and F8 (p=0.021). Altogether, based on findings of the current literature, we can conclude that the tendon transfer procedure suggests electrocortical alterations sensitive to specific qEEG bands.

Changes in quantitative EEG absolute power during the task of catching an object in free fall.

The aim of this study was to verify changes in absolute power (qEEG), in theta, during the catch of a free falling object. The sample consisted of 10 healthy individuals, of both genders, with ages between 25 and 40 years. A three-way ANOVA followed by Post-Hoc analysis was applied. The results demonstrated main effects for time and position. In conclusion, a motor task that involves expectation produces deactivation of non-relevant areas in the ipsilateral hemisphere of the active limb. On the other hand, the patterns of results showed activation in areas responsible for planning and selection of motor repertoires in the contralateral hemisphere.

O objetivo deste estudo é analisar possíveis modificações no córtex cerebral, através da electrencefalografia quantitativa (EEGq), em pacientes submetidos a um procedimento de transferência de tendão (tibial posterior) pela técnica de Srinivasan. Quatro sujeitos (2 homens e 2 mulheres), com média de idade de 49,25 anos (±21,4 DP) foram estudados. Todos os sujeitos realizaram o procedimento cirúrgico devido a hanseníase e tinham, pelo menos, dois anos de pé caído. O EEGq mediu a atividade electrocortical (potencia relativa) entre freqüências de 8 e 25 Hz, no pré e pós-operatório. Um teste t pareado analisou todos os dados (p<0,05). Os resultados mostram alterações significativas na potência relativa em alfa, nos elétrodos F7 (p=0,01) e F8 (p=0,021). Baseados em recentes achados na literatura, podemos concluir que o procedimento de transferência de tendão sugere alterações eletrocorticais sensíveis às freqüên-cias específicas do EEGq.

O objetivo deste estudo foi verificar mudanças na potência absoluta (EEGq), em teta, durante a pegada de objeto em queda livre. A amostra consistiu de 20 indivíduos saudáveis, de ambos os gêneros, com idade entre 25 e 40 anos. Foi utilizada uma ANOVA three-way seguida de uma análise Post-Hoc. Os resultados demonstraram efeito principal para momento e posição. Concluindo, uma tarefa motora que envolve expectativa produz desativação de áreas não-relevantes no hemisfério ipsilateral do membro ativo. Por outro lado, o padrão dos resultados mostrou ativação em áreas responsáveis por planejamento e seleção de repertórios motores no hemisfério contralateral.
