Complex lifestyle intervention among inactive older adults with elevated cardiovascular disease risk and obesity: a mixed-method, single-arm feasibility study for RESTART-a randomized controlled trial.

BACKGROUND: Physical inactivity and obesity are global public health challenges. Older adults are important to target for prevention and management of disease and chronic conditions. However, many individuals struggle with maintaining increased physical activity (PA) and improved diet. This feasibility study provides the foundation for the RESTART trial, a randomized controlled trial (RCT) to test a complex intervention to facilitate favourable lifestyle changes older adults can sustain. The primary objective of this study was to investigate study feasibility (recruitment, adherence, side-effects, and logistics) using an interdisciplinary approach. METHODS: This 1-year prospective mixed-method single-arm feasibility study was conducted in Tromsø, Norway, from September 2017. We invited by mail randomly selected participants from the seventh survey of the Tromsø Study (2015-2016) aged 55-75 years with sedentary lifestyle, obesity, and elevated cardiovascular risk. Participants attended a 6-month complex lifestyle intervention program, comprising instructor-led high-intensive exercise and nutritionist- and psychologist-led counselling, followed by a 6-month follow-up. All participants used a Polar activity tracker for daily activity monitoring during the intervention. Participants were interviewed three times throughout the study. Primary outcome was study feasibility measures. RESULTS: We invited potential participants (n=75) by mail of which 27 % (n=20) agreed to participate. Telephone screening excluded four participants, and altogether 16 participants completed baseline screening. The intervention and test procedures of primary and secondary outcomes were feasible and acceptable for the participants. There were no exercise-induced injuries, indicating that the intervention program is safe. Participants experienced that the dietary and psychological counselling were delivered too early in the intervention and in too close proximity to the start of the exercise program. Minor logistic improvements were implemented throughout the intervention period. CONCLUSION: This study indicates that it is feasible to conduct a full-scale RCT of a multi-component randomized intervention trial, based on the model of the present study. No dropouts due to exercise-induced injury indicates that the exercises were safe. While minor improvements in logistics were implemented during the intervention, we will improve recruitment and adherence strategies, rearrange schedule of intervention contents (exercise, diet, and psychology), as well as improve the content of the dietary and behavioural counselling to maximize outcome effects in the RESTART protocol.

Community-Based Physical Rehabilitation After Percutaneous Coronary Intervention for Acute Myocardial Infarction.

To determine whether a community-based physical rehabilitation program could improve the prognosis of patients who had undergone percutaneous coronary intervention after acute myocardial infarction, we randomly divided 164 consecutive patients into 2 groups of 82 patients. Patients in the rehabilitation group underwent 3 months of supervised exercise training, then 9 months of community-based, self-managed exercise; patients in the control group received conventional treatment. The primary endpoint was major adverse cardiac events (MACE) during the follow-up period (25 ± 15.4 mo); secondary endpoints included left ventricular ejection fraction, 6-minute walk distance, and laboratory values at 12-month follow-up. During the study period, the incidence of MACE was significantly lower in the rehabilitation group (13.4% vs 24.4%; P <0.01). Cox proportional hazards regression analysis indicated a significantly lower risk of MACE in the rehabilitation group (hazard ratio=0.56; 95% CI, 0.37-0.82; P=0.01). At 12 months, left ventricular ejection fraction and 6-minute walk distance in the rehabilitation group were significantly greater than those in the control group (both P <0.01), and laboratory values also improved. These findings suggest that community-based physical rehabilitation significantly reduced MACE risk and improved cardiac function and physical stamina in patients who underwent percutaneous coronary intervention after acute myocardial infarction.

ABSTRACT Introduction: The population of older adults is increasing and an emergent need to implement strategies aimed at recovering or maintaining their health is observed. In this sense, techniques such as Tai Chi could contribute because they have demonstrated bringing diverse benefits for those who practice them, including improvements in the concentration, memory, gait, and equilibrium, a reduction in the risk of falls, a strengthening of the cardiovascular system, and a reduction of stress and depression, among other benefits. Objective: To analyze the scientific evidence on the use of Tai Chi as a health promoter and preserver among older adults. Development: This bibliographic review was conducted during 2013-2019 on the Pubmed, Dialnet, SciELO, LILACS, ScienceDirect and Academic Google databases. The keywords used were Tai Chi Chuan, Tai Ji Quan, and Tai Chi. After filtering through the eligibility criteria, 29 articles were selected for the review. Results: An important percentage of the articles were focused on the attention to physical symptoms which impair the mobility of older adults; nevertheless, some studies addressed psychological issues such as stress, anxiety, sleep disorders, depression, and anger-tension, as well. In these studies, the practice of Tai Chi was associated with health improvements among older adults. Conclusions: Tai Chi is an alternative therapy to promote and maintain health among older adults. This technique is easy to learn, and its practice is not expensive. No adverse reactions during or after the practice of this technique were reported in the studies of this literature review. Therefore, the nursing professional can recommend Tai Chi practice to be implemented as a complementary healthcare measure for older adults.

A Group Dynamics-Based Exercise Intervention to Improve Physical Activity Maintenance in Breast Cancer Survivors.

BACKGROUND: To maintain increases in physical activity (PA), interventions that implement group dynamics principles and strategies with the intent of enhancing group cohesion may be advantageous. This study examined group cohesion and PA following a group dynamics-based PA intervention among breast cancer survivors. METHODS: The study was designed as a pilot randomized controlled trial comparing an 8-week group dynamics-based intervention with an individually supervised intervention. Group cohesion was measured by the Physical Activity Group Environment Questionnaire, and PA was measured at baseline, post-intervention, and 3-month follow-up using a self-report questionnaire and pedometer. RESULTS: Group cohesion levels were high following the intervention and positively associated with PA at 3-month follow-up (ranger = .182-.555). At 3-month follow-up, 91.7% of participants in the group-dynamics-based intervention (n = 12) were classified as moderately active or greater, compared with 54.5% in the individually supervised intervention (n = 11). CONCLUSIONS: These results suggest that, for breast cancer survivors, peer support and fostering group cohesion as part of an exercise program may help to support PA following the completion of a structured intervention. A larger trial with longer follow-up is needed to establish comparative efficacy for a group-dynamics-based exercise intervention to enhance long-term PA adherence in breast cancer survivors.

Clinical research on lumbar oblique-pulling manipulation in combination with sling exercise therapy for patients with chronic nonspecific low back pain

SUMMARY OBJECTIVE: To investigate clinical curative effects of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training on chronic nonspecific lower back pain. METHODS: A total of 60 patients with chronic nonspecific lower back pain in the Outpatient Department were included in this study. These patients were randomly divided into two groups: the observation group and the control group. The control group adopted a single sling-exercise-therapy training three times a week, while the observation group adopted lumbar oblique-pulling manipulation in combination with manipulation treatment once a week. The course of treatment lasted for four weeks. RESULTS: (1) Before and after treatment, the ODI score was compared within the group. A remarkable statistical significance was observed from the third day (P<0.05). At the third month of follow-up, the difference in ODI scores between these two groups was statistically significant (P<0.05). (2) Before and after treatment, it was observed that differences in VAS scores from the third day were statistically significant (P<0.05). (3) The difference in muscle strength between these two groups had remarkable statistical significance in the third month of follow-up (P<0.05). CONCLUSION: The effective rehabilitation function of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training in patients with CNLBP is superior to that of sling-exercise-therapy training alone.

RESUMO OBJETIVO: Investigar os efeitos curativos da manipulação lombar com o movimento de puxar oblíquo combinado a terapia por exercícios de sling-training para dor lombar baixa crônica não específica. METODOLOGIA: Um total de 60 pacientes com dor lombar baixa crônica não específica no ambulatório foram incluídos neste estudo. Esses pacientes foram divididos aleatoriamente em dois grupos: o grupo de observação e o grupo de controle. O grupo de controle aderiu apenas à terapia por exercícios de sling-training três vezes por semana, enquanto o grupo de observação aderiu à manipulação lombar com o movimento de puxar oblíquo combinado à terapia por exercícios de sling-training uma vez por semana. O tratamento durou quatro semanas. RESULTADOS: (1) Antes e após o tratamento, o escore de ODI foi comparado no grupo. Uma significância estatística notável foi observada a partir do terceiro dia (P<0,05). No terceiro mês de acompanhamento, a diferença nos escores de ODI entre os dois grupos foi estatisticamente significante (P<0,05). (2) Antes e após o tratamento, observou-se que diferenças nos escores de VAS a partir do terceiro dia foram estatisticamente significantes (P< 0,05). (3) A diferença de força muscular entre os dois grupos apresentou significância estatística notável no terceiro mês de acompanhamento (p<0,05). CONCLUSÃO: A função de reabilitação efetiva da manipulação lombar com o movimento de puxar oblíquo combinada à terapia por exercícios de sling-training em pacientes com dor lombar baixa crônica não específica é superior à da terapia por exercícios de sling-training sozinha.

Effectiveness of a Home-Based Active Video Game Programme in Young Cystic Fibrosis Patients.

BACKGROUND: Exercise-based rehabilitation is already a part of cystic fibrosis (CF) treatment; however, patient adherence is low. OBJECTIVES: To assess the effectiveness of a home exercise programme using active video games (AVGs) as a training modality for children and adolescents with CF. METHODS: Thirty-nine children with CF were randomised to a control group (CG, n = 20, age 11 ± 6 years; FEV1 86.2 ± 20.5% of predicted) or a training group (AVGG, n = 19, age 13 ± 3 years; FEV1 82.7 ± 21.7% of predicted). The home training protocol consisted of 30- to 60-min sessions, 5 days/week, for 6 weeks using a Nintendo Wii™ platform. Exercise capacity was measured by the 6-min walk test (6MWT) and modified shuttle walk test (MSWT); muscular strength was estimated using the horizontal jump test (HJT), medicine ball throw (MBT), and hand grip strength (right [RHG]; left [LHG]); and quality of life was rated using the Cystic Fibrosis Questionnaire-Revised (CFQ-R). All the children were measured at baseline, after rehabilitation, and at 12 months. RESULTS: For the group × time interaction ANOVAs, the AVGG showed significant between-group differences in exercise capacity: 6MWT farthest walking distance, 38.4 m (p < 0.01); MSWT farthest walking distance, 78.4 m (p < 0.05); and muscular strength: HJT 9.8 cm, MBT 30.8 cm, RHG 7 kg, and LHG 6.5 kg (p < 0.01), before versus after intervention. The CFQ-R reported significantly higher scores on respiratory symptoms after the intervention and favoured the AVGG, and there was an improvement in other domains after 12 months. Adherence to the home exercise programme was 95% during the 6- week intervention period. CONCLUSION: A home-based programme using AVGs can effectively improve exercise capacity, muscular strength and quality of life in the short-term in children and adolescents with CF. The effects of training on muscle performance and quality of life were sustained over 12 months.

Effects of simple long-term respiratory care strategies in older men with COPD / Efeitos de estratégias de longo prazo simples de cuidados respiratórios em homens idosos com DPOC

ABSTRACT Objective: To evaluate a 24-month supervised, community-based maintenance exercise program after 3 months of pulmonary rehabilitation (PR) in comparison with a 27-month physical activity counseling program, in terms of the effects on maximal muscle strength, muscle power output, and exercise capacity, in individuals with COPD. Methods: Sixty-three men with moderate-to-severe COPD were recruited from two previous studies. Of those 63 participants, 31 were offered 3 months of PR followed by a 24-month supervised maintenance exercise program (24MME group) and 32 were offered a 27-month physical activity counseling program (27MPAC group). Measurements at 3 months and at the end of the study period included maximal strength of the upper and lower limbs, power output of the lower limbs, six-minute walk distance (6MWD), and quality of life. Results: At 27 months, the improvements in maximal strength of the upper and lower limbs were greater in the 24MME group than in the 27MPAC group (37.6 ± 28.3% and 28.4 ± 13.3%, respectively, vs. 8.8 ± 16% and 13.6 ± 16.4%, respectively; p < 0.05), as was the improvement in power output of the lower limbs (24.6 ± 18.4% vs. −2.3 ± 28.5%; p < 0.01). The increase in the 6MWD after 3 months was also greater in the 24MME group than in the 27MPAC group (33.2 ± 36.6 m vs. 2.9 ± 34.7 m; p < 0.05), although there were no differences between the two groups in terms of the Δ6MWD at 27 months (vs. baseline). Conclusions: A supervised, community-based maintenance program is a successful long-term strategy to preserve the benefits of PR on peripheral muscle function and exercise capacity in individuals with COPD. However, physical activity counseling can maintain maximal muscle strength and exercise capacity in such individuals.

RESUMO Objetivo: Avaliar um programa comunitário supervisionado de 24 meses de exercícios de manutenção precedido de 3 meses de reabilitação pulmonar (RP) em comparação com um programa de 27 meses de aconselhamento de atividade física, quanto aos efeitos na força muscular máxima, potência muscular e capacidade de exercício em indivíduos com DPOC. Métodos: Foram recrutados 63 homens com DPOC moderada a grave de dois estudos anteriores. A 31 desses 63 participantes foram oferecidos 3 meses de RP seguidos de um programa supervisionado de 24 meses de exercícios de manutenção (grupo 24MEM), e a 32, um programa de 27 meses de aconselhamento de atividade física (grupo 27MAAF). Medidas realizadas aos 3 meses e ao final do período estudado incluíram força máxima dos membros superiores e inferiores, potência dos membros inferiores, distância percorrida no teste de caminhada de seis minutos (DTC6) e qualidade de vida. Resultados: Aos 27 meses, a melhora da força máxima dos membros superiores e inferiores foi maior no grupo 24MEM que no grupo 27MAAF (37,6 ± 28,3% e 28,4 ± 13,3%, respectivamente, vs. 8,8 ± 16% e 13,6 ± 16,4%, respectivamente; p < 0,05), e houve melhora da potência dos membros inferiores (24,6 ± 18,4% vs. −2,3 ± 28,5%; p < 0,01). O aumento da DTC6 após 3 meses também foi maior no grupo 24MEM que no grupo 27MAAF (33,2 ± 36,6 m vs. 2,9 ± 34,7 m; p < 0,05), mas não houve diferenças entre os grupos quanto a ΔDTC6 aos 27 meses (vs. basal). Conclusões: Um programa comunitário supervisionado de manutenção é uma estratégia de longo prazo bem sucedida para preservar os benefícios da RP na função muscular periférica e capacidade de exercício em indivíduos com DPOC. No entanto, o aconselhamento de atividade física consegue manter a força muscular máxima e a capacidade de exercício nesses indivíduos.

Myofunctional Therapy to Treat Obstructive Sleep Apnea: A Systematic Review and Meta-analysis.

OBJECTIVE: To systematically review the literature for articles evaluating myofunctional therapy (MT) as treatment for obstructive sleep apnea (OSA) in children and adults and to perform a meta-analysis on the polysomnographic, snoring, and sleepiness data. DATA SOURCES: Web of Science, Scopus, MEDLINE, and The Cochrane Library. REVIEW METHODS: The searches were performed through June 18, 2014. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was followed. RESULTS: Nine adult studies (120 patients) reported polysomnography, snoring, and/or sleepiness outcomes. The pre- and post-MT apneahypopnea indices (AHI) decreased from a mean ± standard deviation (M ± SD) of 24.5 ± 14.3/h to 12.3 ± 11.8/h, mean difference (MD) -14.26 [95% confidence interval (CI) -20.98, -7.54], P < 0.0001. Lowest oxygen saturations improved from 83.9 ± 6.0% to 86.6 ± 7.3%, MD 4.19 (95% CI 1.85, 6.54), P = 0.0005. Polysomnography snoring decreased from 14.05 ± 4.89% to 3.87 ± 4.12% of total sleep time, P < 0.001, and snoring decreased in all three studies reporting subjective outcomes. Epworth Sleepiness Scale decreased from 14.8 ± 3.5 to 8.2 ± 4.1. Two pediatric studies (25 patients) reported outcomes. In the first study of 14 children, the AHI decreased from 4.87 ± 3.0/h to 1.84 ± 3.2/h, P = 0.004. The second study evaluated children who were cured of OSA after adenotonsillectomy and palatal expansion, and found that 11 patients who continued MT remained cured (AHI 0.5 ± 0.4/h), whereas 13 controls had recurrent OSA (AHI 5.3 ± 1.5/h) after 4 y. CONCLUSION: Current literature demonstrates that myofunctional therapy decreases apnea-hypopnea index by approximately 50% in adults and 62% in children. Lowest oxygen saturations, snoring, and sleepiness outcomes improve in adults. Myofunctional therapy could serve as an adjunct to other obstructive sleep apnea treatments.
