based interventions showed significantly improved anxiety ( g = 0.35 , 95 % CI 0.09 , 0.62 , I2 = 92 %) compared to controls . With regards to moderators , researchers reported higher attrition , they reported less beneficial effects on anxiety symptoms ( β = -0.001 , Qmodel = 4.59 , p = . 032 ). No other quality indicators moderated the effects of online mindfulness-based interventions on anxiety .
Conclusion : Online mindfulnessbased interventions improved anxiety symptoms in adult population . Thus , it might be used as adjunctive or alternative complementary treatment for adults . However , our findings must be interpreted with caution due to the low and unclear power of the sample in primary studies ; hence , high-quality studies are needed to confirm our findings .

Background : Posttraumatic stress disorder ( PTSD ) can occur after trauma . While PTSD management strategies include first-line pharmacotherapy and psychotherapy , mind – body therapies , such as yoga , are applied in the PTSD population . This overview aimed to summarize the effectiveness of yoga interventions on PTSD symptoms in adults in a systematic review ( SR ) including randomized controlled trials ( RCTs ).
Method : We searched for SR with or without meta-analysis of RCTs involving adults with PTSD diagnosis or trauma history . The search was conducted until April 2022 , through six databases ( Cochrane Database , MEDLINE ( Pubmed ), Scopus , Embase , CINHAL and PEDro ). The primary outcome was the evolution of PTSD symptoms throughout the intervention . Secondary outcomes included follow-up , safety , adherence , and cost of the intervention .
Two authors independently performed the selection , data extraction and risk of bias assessment with the AMSTAR 2 tool and overlap calculation . This overview is a qualitative summary of the results obtained in the selected studies .
Results : Eleven SRs were analyzed , of which 8 included meta-analyses . The overlap between studies was considered very high ( corrected covered area of 21 %). Fifty-nine RCTs involving 4434 participants were included . Yoga had a significant small-to-moderate effect-size on PTSD symptom decrease in 7 SRs and non-significant effects in 1 SR with metaanalysis . All SR without meta-analysis found beneficial effects of yoga on PTSD . Secondary outcomes were not sufficiently assessed to provide clear evidence . Results should be interpreted with caution as 1 SR was rated as at moderate risk of bias , 3 as low and 7 as critically low .
Conclusions : While yoga therapy seems promising for decreasing PTSD symptoms , future research should standardize yoga therapy duration / frequency / type and consider long-term efficacy to better delineate yoga therapy efficacy in PTSD patients .

Background : Patients with a history of COVID-19 infection may suffer from different physical problems . This study aimed to investigate the effect of corrective and breathing exercises on improving respiratory function among patients with a history of COVID-19 infection .
Methods : In this clinical trial study , thirty elderlies with a history of COVID-19 disease were divided into two groups ( mean age 63.60 ± 3.56 experimental , 59.87 ± 2.99 control groups ) based on the study inclusion criteria . Exercise interventions included two sections- breathing exercises and corrective exercises in the cervical and thoracic spine . The spirometry test , craniovertebral angle , and thoracic kyphosis test were used . To evaluate differences between variables , pairedsamples t-test and ANCOVA were used ( p-value < 0.01 ). Also , Eta-squared was measured to assess the effect size .
Results : Results showed a significant difference between the two groups in craniovertebral angle ( P = 0.001 ), thoracic kyphosis ( P = 0.007 ), and respiratory capacity including Forced expiratory volume in one second ( FEV1 ) ( P = 0.002 ), FEV1 / FVC ( P = 0.003 ), Peripheral oxygen saturation ( SPO2 ) ( P = 0.001 ), while no significant differences were observed between two groups in terms of chest anthropometric indices ( P > 0.01 ). The Eta-squared value of 0.51 for the Craniovertebral angle and the SPO2 indicates a large effect size .
Conclusions : The results showed the combination of corrective and breathing exercises could improve pulmonary function and correct cervical and thoracic posture in patients with a history of COVID-19 infection . Therefore , corrective and breathing exercises can be helpful as a complementary treatment along with pharmaceutical therapy to reduce chronic pulmonary complications in patients infected with COVID-19 .
