The effect of inspiratory muscle training on respiratory variables in a patient with ankylosing spondylitis: A case report

The Efficiency of Respiratory Exercises in Rehabilitation of Low Back Pain: A Systematic Review and Meta-Analysis

BACKGROUND

Low back pain (LBP) is a common musculoskeletal disorder, and respiratory exercise is considered a nonsurgical management method. Therefore, this systematic review and meta-analysis aims to estimate the results of randomized controlled trials on the effect of respiratory training in reducing LBP and its dose relationship.

METHODS

The present study was conducted from January 2020 to January 2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (2020). Relevant studies were searched in multiple databases including PubMed, Web of Science, the Cochrane Library, EBSCO, Scopus, ScienceDirect, Wan Fang and China Knowledge Network, ClinicalTrials.gov, and Google Scholar, using a combination of MeSH/Emtree terms and free-text words. The heterogeneity of the studies was assessed using the I2 statistic.

RESULTS

A total of 14 publications were included in the meta-analysis, with a total sample size of 698 individuals, aged 60-80 years. Respiratory exercise was effective in relieving LBP (standardized mean difference = -0.87, P < .00001) and improving physical disability (standardized mean difference = -0.79, P < .00001). The type of breathing and the total duration of breathing exercises were found to be the source of heterogeneity in this study by subgroup analysis. Subgroup analysis revealed that the most significant effect sizes of breathing resistance exercise to reduce LBP and the most significant effect sizes of breathing relaxation techniques to alleviate physical disability were performed 3 to 5 times per week and period >4 weeks. Respiratory exercise reducing LBP and improving functional disability was most effective when the total duration of the intervention was >500 minutes. Funnel plots showed that the results of the 2 overall studies were reliable without publication bias.

CONCLUSIONS

Respiratory exercise can effectively reduce LBP and improve physical disability. Therefore, these exercises can be regarded as a part of a LBP management plan. We recommend an exercise program with 30 to 50 minutes, 3 to 5 times per week, and >4 weeks of breathing resistance exercise program as the most effective for treating LBP.

The effects of Pilates training on respiratory muscle strength in patients with ankylosing spondylitis

BACKGROUND

Reduction in flexibility and mobility are important factors that lead to impairments in quality of life, reduction of exercise tolerance, and a decreased pulmonary capacity with the progression of Ankylosing Spondylitis (AS).

AIM

The purpose of this study was to investigate the effects of Pilates exercises on mobility, quality of life, and respiratory muscle strength in patients with AS.

METHODS

Forty patients with AS were randomly divided into two groups as Pilates group and the control group. The Pilates group performed Pilates exercises in supervised group sessions and the control group performed conventional exercises at home three days a week for eight weeks. The main outcome measure was respiratory muscle strength. Secondary outcome measures were forced vital capacity (FVC), forced expiratory volume in one second (FEV1) FEV1/FVC ratio, chest expansion, Bath indices (BASDAI, BASMI), Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) and six-minute walk test (6MWT). All participants were assessed by a blind assessor at baseline and the end of eight weeks.

RESULTS

Thirty-six AS patients (n = 19 in the Pilates group, n = 17 in the control group) completed the study. Respiratory muscle strength, FEV1/FVC, chest expansion, BASDAI, BASMI, ASQoL, and 6MWT significantly improved at the 8th week (p < .05) in the Pilates group, while inspiratory muscle strength, FEV1/FVC, chest expansion, and 6MWT showed significant improvements in the control group at 8th week compared to baseline (p < .05). No significant between-group differences were observed when the change over time values were compared (Δ).

CONCLUSION

Both Pilates and home exercises seem to be effective for improving respiratory parameters and functional status in patients with AS. Pilates exercises without using any equipment and additional exercises is found to be useful for improving respiratory functions and disease-related symptoms.

Correlation between vital capacity and vertebra body translation during lumbar flexion and extension in adults aged between 60 and 69 years

BACKGROUND

Low back pain is one of the most common musculoskeletal diseases in the modern society, causing a huge economic burden, and has become an important public health problem. Years lived with disability caused by low back pain increased rapidly as a result of population growth and ageing worldwide, with the biggest increase seen in low-income and middle-income countries. In this context, the prevention and treatment of low back pain in the elderly warrant attention and research.

OBJECTIVE

The aim is to determine the correlation between vital capacity (VC) and vertebral body translation during lumbar flexion and extension in adults aged 60 to 69 years.

METHODS

A total of 192 adults aged 60 to 69 years were selected by cluster sampling in Lishui City, Zhejiang Province, China. The VC of the study population was tested and the ratio of VC to body mass (BM) was calculated. The lumbar hyperextension and hyperflexion of the study population were radiographed using a Hitachi 500 mAs X-ray machine made in Japan to verify vertebral body translations in each segment.

RESULTS

The differences of test values of VC (P= 0.004), VC/BM ratio (P= 0.012) and vertebral body translation in the L5-S1 segment during flexion and extension (P< 0.001) of the populations aged 60 to 64 and 65 to 69 years were all statistically significant. The vertebral body translation in the L5-S1 segment during lumbar flexion and extension in the population aged 60 to 69 years was negatively correlated with the VC (rs =-0.207 and P= 0.004) and VC/BM ratio (rs =-0.248 and P= 0.001), showing statistical significance.

CONCLUSIONS

The vertebral body translation of during lumbar flexion and extension correlates with the VC in the population aged 60 to 69 years. Recognition of this correlation may help to guide further lumbar stabilization exercises.

Potential Role of Yoga in the Management of Ankylosing Spondylitis: A Retrospective Study

BACKGROUND

Ankylosing spondylitis (AS) is a chronic autoimmune inflammatory spondyloarthropathy with unclear pathogenesis. The inflammatory pain in AS leads to restricted spinal mobility and significant disability. Yoga is a nonpharmacological intervention that has positive effects on various musculoskeletal-related problems. However, its role in AS is unknown.

OBJECTIVE

The present retrospective study assessed the efficacy of a two-week residential yoga intervention on spinal flexibility among AS patients.

METHODS

The records for 24 male AS patients within the age range 30 to 50 years (average age 38.3 ± 10.5 years) who underwent a two-week residential yoga retreat between 2015 and 2020 were obtained from a yoga center located in South India. Yoga intervention consisted of yoga postures, breathing practices, meditation, a healthy diet, and devotional sessions. Pre and Post data of the sit-and-reach test, blood pressure, heart rate, and symptom score were analyzed using Statistical Package for Social Sciences (SPSS).

RESULTS

Compared to the baseline, the post scores of the sit-and-reach test, systolic blood pressure and heart rate were found to be significantly (P < .05) lower. The symptom score and analgesic medication score also showed significant improvement after two-weeks compared to the baseline.

CONCLUSION

This retrospective study indicates the positive impact of on and analgesic use among AS patients. However, additional studies using robust research designs are warranted.
