Effects of a short-term aquatic exercise intervention on symptoms and exercise capacity in individuals with chronic fatigue syndrome/myalgic encephalomyelitis: a pilot study

Sustainability of a Motor Control Exercise Intervention: Analysis of Long-Term Effects in a Low Back Pain Study

Development of chronic pain after a low back pain episode is associated with increased pain sensitivity, altered pain processing mechanisms and the influence of psychosocial factors. Although there is some evidence that multimodal therapy (such as behavioral or motor control therapy) may be an important therapeutic strategy, its long-term effect on pain reduction and psychosocial load is still unclear. Prospective longitudinal designs providing information about the extent of such possible long-term effects are missing. This study aims to investigate the long-term effects of a homebased uni- and multidisciplinary motor control exercise program on low back pain intensity, disability and psychosocial variables. 14 months after completion of a multicenter study comparing uni- and multidisciplinary exercise interventions, a sample of one study center (n = 154) was assessed once more. Participants filled in questionnaires regarding their low back pain symptoms (characteristic pain intensity and related disability), stress and vital exhaustion (short version of the Maastricht Vital Exhaustion Questionnaire), anxiety and depression experiences (the Hospital and Anxiety Depression Scale), and pain-related cognitions (the Fear Avoidance Beliefs Questionnaire). Repeated measures mixed ANCOVAs were calculated to determine the long-term effects of the interventions on characteristic pain intensity and disability as well as on the psychosocial variables. Fifty four percent of the sub-sample responded to the questionnaires (n = 84). Longitudinal analyses revealed a significant long-term effect of the exercise intervention on pain disability. The multidisciplinary group missed statistical significance yet showed a medium sized long-term effect. The groups did not differ in their changes of the psychosocial variables of interest. There was evidence of long-term effects of the interventions on pain-related disability, but there was no effect on the other variables of interest. This may be partially explained by participant's low comorbidities at baseline. Results are important regarding costless homebased alternatives for back pain patients and prevention tasks. Furthermore, this study closes the gap of missing long-term effect analysis in this field.

Long COVID and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)-A Systemic Review and Comparison of Clinical Presentation and Symptomatology

Background and Objectives: Long COVID defines a series of chronic symptoms that patients may experience after resolution of acute COVID-19. Early reports from studies with patients with long COVID suggests a constellation of symptoms with similarities to another chronic medical illness-myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). A review study comparing and contrasting ME/CFS with reported symptoms of long COVID may yield mutualistic insight into the characterization and management of both conditions. Materials and Methods: A systemic literature search was conducted in MEDLINE and PsycInfo through to 31 January 2021 for studies related to long COVID symptomatology. The literature search was conducted in accordance with PRISMA methodology. Results: Twenty-one studies were included in the qualitative analysis. Long COVID symptoms reported by the included studies were compared to a list of ME/CFS symptoms compiled from multiple case definitions. Twenty-five out of 29 known ME/CFS symptoms were reported by at least one selected long COVID study. Conclusions: Early studies into long COVID symptomatology suggest many overlaps with clinical presentation of ME/CFS. The need for monitoring and treatment for patients post-COVID is evident. Advancements and standardization of long COVID research methodologies would improve the quality of future research, and may allow further investigations into the similarities and differences between long COVID and ME/CFS.

[Medical rehabilitation of patients with pneumonia associated with the new COVID-19 coronavirus infection]

Effective medical rehabilitation of patients with pneumonia caused by the new SARS-CoV-2 coronavirus is critical for the recovery and optimization of emergency and specialty care outcomes. In this regard, it is relevant to develop a scientifically based medical rehabilitation program for patients with the coronavirus infectious disease COVID-19, whose composition and structure includes methods and tools that have proven effectiveness.

AIM

To develop evidence-based approaches to medical rehabilitation for patients with pneumonia associated with the new COVID-19 coronavirus infection.

RESULTS

The clinical effects and suggested mechanisms of action of rehabilitation technologies in patients with pneumonia, including those associated with the new COVID-19 coronavirus infection, are considered in Detail. The most studied of the physical methods that have a proven effect are physical exercises, breathing exercises, the complex effect of factors of resort therapy, hydrotherapy, which affect the main clinical manifestations of the underlying disease, astheno-neurotic syndrome and increasing immunity. Clinical recommendations for medical rehabilitation are proposed and its promising methods are considered.

CONCLUSION

Regular generalization and analysis of high-quality randomized controlled clinical trials to evaluate various physical methods of treatment of patients with pneumonia associated with the new COVID-19 coronavirus infection is Necessary, which serve as a basis for the development of future valid clinical recommendations. Timely and adequate specialized medical rehabilitation care is critical to maintaining the health, reducing disability and mortality of patients with pneumonia associated with the new COVID-19 coronavirus infection.

A Comparison of 6 Weeks of Aquatic Exercise and Kinesio Taping in Patients With Chronic Nonspecific Low Back Pain

CONTEXT

In many societies, although chronic low back pain (LBP) is a significant problem, there is no consensus on the optimal therapeutic intervention.

OBJECTIVE

To compare the impact of aquatic exercise (AE) and kinesio taping (KT) on the pain intensity and functional incapacity in women with chronic nonspecific LBP.

DESIGN

Randomized controlled trial.

SETTING

Outpatient clinic.

PARTICIPANTS

Thirty-six women with chronic nonspecific LBP (mean [SD]: age = 50.69 [4.187] y) participated.

INTERVENTIONS

Participants randomly assigned to AE (n = 12), KT (n = 12), and nontreatment control (n = 12) groups for 6 weeks.

MAIN OUTCOME MEASURES

Pain intensity and functional disability were evaluated at baseline and the end of the intervention.

RESULTS

Pain intensity decreased more in the AE group than in the KT group (5.9-0.5 cm [91.6% decrease] vs 5.7-2.4 cm [58.1% decrease], respectively; P < .001 for both after Bonferroni post hoc test); the values decreased more in the 2 treatment groups than in the control group (P < .001 for between-group comparisons). Disability decreased more in the AE group (43.2%-18.8% [55.6% decrease]) than the KT group (37.8%-19.3% [48.3% decrease]) (P < .001 for both comparisons), but increased in the control group (38.7%-41.2% [6.5% increase]; P = .045).

CONCLUSION

These results suggest AE and KT treatment methods provide pain intensity and disability improvements in women with chronic nonspecific LBP. Nevertheless, AE was more effective than KT.

Hand Grip Strength as a Clinical Biomarker for ME/CFS and Disease Severity

Background: The diagnosis of myalgic encephalomyelitis (ME/CFS) in research and clinical practice has largely relied on clinical history, which can be subjective in nature. Clinical signs are often subtle, overlap with other conditions, and are not formally included as part of diagnostic workup. The characterization of clinical signs and biomarkers is needed for better diagnosis and classification of patients and to monitor treatment response. Hand grip strength (HGS) has been used as an objective measure of muscle strength and fatigue, which is a primary symptom of ME/CFS. We assessed the potential usefulness of HGS as a diagnostic marker in ME/CFS. Methods: We compared HGS measurements from participants in the UK ME/CFS Biobank, with groups consisting of people with ME/CFS of differing severity (n = 272), healthy (n = 136), multiple sclerosis (n = 76) controls, and others with chronic fatigue not meeting the diagnosis of ME/CFS (n = 37). We correlated the maximum and minimum of, and differences between, 3 repeated HGS measurements with parameters of disease severity, including fatigue and pain analog scales, and physical and mental component summaries from the SF-36v2TM questionnaire across recruitment groups. Results: HGS indicators were associated with having ME/CFS, with magnitudes of association stronger in severely affected than in mild/moderately affected patients. Compared with healthy controls, being severely affected was associated with a reduction in minimum HGS of 15.3 kg (95%CI 19.3-11.3; p < 0.001), while being mild/moderately affected was associated with a 10.5 kg (95%CI 13.2-7.8; p < 0.001) reduction. The association persisted after adjusting for age, sex and body mass index. ME/CFS cases also showed lower values of maximum HGS and significant drops in values from the first to second and third trials, compared to other study groups. There were significant correlations between HGS indicators and clinical parameters of disease severity, including fatigue analog scale (Spearman's Rho = -0.40, p < 0.001), pain analog scale (Rho = -0.38, p < 0.001), and physical component summary (Rho = 0.42, p < 0.001). Discussion: HGS is markedly reduced in ME/CFS, particularly in patients with more severe disease, and may indicate muscle and fatigue related symptoms. HGS is a potential diagnostic tool in ME/CFS, and could also be used to enhance patient phenotyping and as an outcome measure following interventions.
