RESUMO
BACKGROUND: Duchene muscular dystrophy (DMD) is a progressive muscular disorder. Cardiac disorder is the second-most common cause of death in children with DMD, with 10%-20% of them dying of cardiac failure. Heart rate variability (HRV) is shown to be a predictor of cardio-autonomic function. Physiotherapy (PT) is advised for these children as a regular treatment for maintaining their functional status. The effect of yogic practices on the cardio-autonomic functions has been demonstrated in various neurological conditions and may prove beneficial in DMD. MATERIALS AND METHODS: In this study, 124 patients with DMD were randomized to PT alone or PT with yoga intervention. Home-based PT and yoga were advised. Adherence was serially assessed at a follow-up interval of 3 months. Error-free, electrocardiogram was recorded in all patients at rest in the supine position. HRV parameters were computed in time and frequency domains. HRV was recorded at baseline and at an interval of 3 months up to 1 year. Repeated-measures ANOVA was used to analyze longitudinal follow-up and least significant difference for post hoc analysis and P < 0.05 was considered statistically significant. RESULTS: In our study, with PT protocol, standard deviation of NN, root of square mean of successive NN, total power, low frequency, high-frequency normalized units (HFnu), and sympathovagal balance improved at varying time points and the improvement lasted up for 6-9 months, whereas PT and yoga protocol showed an improvement in HFnu during the last 3 months of the study period and all the other parameters were stable up to 1 year. Thus, it is evident that both the groups improved cardiac functions in DMD. However, no significant difference was noted in the changes observed between the groups. CONCLUSION: The intense PT and PT with yoga, particularly home-based program, is indeed beneficial as a therapeutic strategy in DMD children to maintain and/or to sustain HRV in DMD.
RESUMO
OBJECTIVE: To study the add-on effects of pranayama and meditation in rehabilitation of patients with Guillain-Barré syndrome (GBS). PATIENTS AND METHOD: This randomized control pilot study was conducted in neurological rehabilitation unit of university tertiary research hospital. Twenty-two GBS patients, who consented for the study and satisfied selection criteria, were randomly assigned to yoga and control groups. Ten patients in each group completed the study. The yoga group received 15 sessions in total over a period of 3 weeks (1 h/session), one session per day on 5 days per week that consisted of relaxation, Pranayama (breathing practices) and Guided meditation in addition to conventional rehabilitation therapeutics. The control group received usual rehabilitation care. All the patients were assessed using Pittsburgh Sleep Quality Index, Numeric pain rating scale, Hospital anxiety and Depression scale and Barthel index score. Mann-Whitney U test and Wilcoxon's signed rank test were used for statistical analysis. RESULTS: Quality of sleep improved significantly with reduction of PSQI score in the yoga group (p = 0.04). There was reduction of pain scores, anxiety and depression in both the groups without statistical significance between groups (pain p > 0.05, anxiety p > 0.05 and depression p > 0.05). Overall functional status improved in both groups without significant difference (p > 0.05). CONCLUSIONS: Significant improvement was observed in quality of sleep with yogic relaxation, pranayama, and meditation in GBS patients.
