Proof of Concept of a 6-Month Person-Oriented Exercise Intervention 'MultiPill-Exercise' among Patients at Risk of or with Multiple Chronic Diseases: Results of a One-Group Pilot Trial

Physical exercise has been shown to be effective in the treatment of non-communicable chronic diseases. However, patients with multiple chronic diseases (multimorbidity) have received little attention in health policy. This pilot trial served as a proof of concept of a 6-months person-oriented exercise intervention for people at risk of or with diagnosed cardiovascular diseases, diabetes mellitus type 2, overweight and/or hip/knee osteoarthritis, regarding effects on health outcomes as well as adherence and safety. The intervention (‘MultiPill-Exercise’) was designed to promote physical exercise participation, considering an individual perspective by addressing personal and environmental factors. Outcomes were assessed at baseline (t0) and after three- (t3) and six-months (t6). The primary outcome was self-reported physical exercise participation in minutes/week comparing t3 and t6 vs. t0. Secondary outcomes included cardio-respiratory fitness (maximum oxygen uptake VO2peak during incremental cycling ergometry), isometric peak torque of knee extensors and flexors, health-related quality of life (Veterans Rand 12 with its subscales of perceived general health (GH), mental health (MCS), and physical health (PCS)) and blood levels. Adherence to exercise (% of attended sessions during the first 12-weeks of the intervention) and adverse events were monitored as well. Data were analyzed using a non-parametric procedure for longitudinal data, estimating rank means (MRank) and relative treatment effects (RTE) as well as linear-mixed effect models for parametric data. The primary endpoint of physical exercise participation was significantly higher at t3 and t6 compared to baseline (t3 vs. t0: MRank = 77.1, p < 0.001, RTE: 0.66; t6 vs. t0: MRank = 70.6, p < 0.001, RTE = 0.60). Improvements at both follow-up time points compared to t0 were also found for relative VO2peak (t3 vs. t0 = 2.6 mL/kg/min, p < 0.001; t6 vs. t0 = 2.0 mL/kg/min, p = 0.001), strength of knee extensors (t3 vs. t0 = 11.7 Nm, p = 0.007; t6 vs. t0= 18.1 Nm, p < 0.001) and GH (t3 vs. t0 = 16.2, p = 0.003; t6 vs. t0 = 13.4, p = 0.008). No changes were found for MCS, PCS and for blood levels. Overall exercise adherence was 77%. No serious adverse events were recorded. Results of this pilot trial represent a first proof of concept for the intervention ‘MultiPill-Exercise’ that will now be implemented and evaluated in a real-world health care setting.

Effectiveness of a personal health coaching intervention (diabetescoach) in patients with type 2 diabetes: protocol for an open-label, pragmatic randomised controlled trial

INTRODUCTION

The widespread prevalence of type 2 diabetes (T2D) not only influences patients' daily lives but also has an economic impact on society. Increasing physical activity and a healthy diet can delay the progression of T2D. Although there are evidence-based recommendations on diet and physical activity, patients with T2D have difficulties implementing them. An appropriate lifestyle intervention can address this problem.

METHODS AND ANALYSIS

This study is based on the need to develop an intervention that helps patients to establish behavioural changes in order to achieve glycaemic control. The intervention will be evaluated in a monocentric, open-label, pragmatic, two-arm randomised controlled trial with a sample ratio of 1:1 and a parallel design. This superiority study will be conducted in Switzerland. All enrolled patients (n=90) will receive the standard medical treatment for T2D. The intervention group will receive personal health coaching by telephone and access to a smartphone and web application for 1 year. The control group will receive access to the application for 1 year and a one-time written diet and exercise recommendation. The primary outcomes are objectively measured physical activity and glycated haemoglobin. Secondary outcomes are self-reported physical activity, nutrition, cognitive mediators of changes in sport-related behaviour, blood values, medication and nutritional supplements, anthropometric data, quality of life, neuropathy and cost-effectiveness. All outcomes will be measured at baseline, at 27 weeks after inclusion and at 54 weeks after inclusion. The recruitment of participants and the measurements will be completed after 2 years. Linear mixed-effects models will be applied for each outcome variable to analyse the intervention effects.

ETHICS AND DISSEMINATION

This study was approved by the Ethics Committee North-western and Central Switzerland in February 2021 (ref: 2020-02755). All participants will be required to provide written informed consent. The results will be published in international peer-reviewed journals.

Efficacy and cost-effectiveness of a Transdiagnostic group-based exercise intervention: study protocol for a pragmatic multi-site randomized controlled trial

BACKGROUND

Mental disorders are prevalent and cause considerable burden of disease. Exercise has been shown to be efficacious to treat major depressive disorders, insomnia, panic disorder with and without agoraphobia and post traumatic stress disorder (PTSD).

METHODS

This pragmatic, two arm, multi-site randomised controlled trial will evaluate the efficacy and cost-effectiveness of the manualized, group-based six-months exercise intervention "ImPuls", among physically inactive patients with major depressive disorders, insomnia, panic disorder, agoraphobia and PTSD within a naturalistic outpatient context in Germany. A minimum of 375 eligible outpatients from 10 different study sites will be block-randomized to either ImPuls in addition to treatment as usual (TAU) or TAU only. ImPuls will be conducted by trained exercise therapists and delivered in groups of six patients. The program will combine (a) moderate to vigorous aerobic exercise carried out two-three times a week for at least 30 min with (b) behavior change techniques for sustained exercise behavior change. All outcomes will be assessed pre-treatment, post-treatment (six months after randomization) and at follow-up (12 months after randomization). Primary outcome will be self-reported global symptom severity assessed with the Brief Symptom Inventory (BSI-18). Secondary outcomes will be accelerometry-based moderate to vigorous physical activity, self-reported exercise, disorder-specific symptoms, quality-adjusted life years (QALY) and healthcare costs. Intention-to-treat analyses will be conducted using mixed models. Cost-effectiveness and cost-utility analysis will be conducted using incremental cost-effectiveness and cost-utility ratios.

DISCUSSION

Despite its promising therapeutic effects, exercise programs are currently not provided within the outpatient mental health care system in Germany. This trial will inform service providers and policy makers about the efficacy and cost-effectiveness of the group-based exercise intervention ImPuls within a naturalistic outpatient health care setting. Group-based exercise interventions might provide an option to close the treatment gap within outpatient mental health care settings.

TRIAL REGISTRATION

The study was registered in the German Clinical Trials Register (ID: DRKS00024152 , 05/02/2021).

Bewegungstherapie und Bewegungsförderung in der Rehabilitation – Aufgaben und Ziele für Forschung und Entwicklung

Während bewegungstherapeutische Maßnahmen einen Großteil der Leistungen in der medizinischen Rehabilitation ausmachen, war die wissenschaftliche Auseinandersetzung mit Bewegungstherapie in der Rehabilitation lange Zeit vergleichsweise gering ausgeprägt. Dieses Missverhältnis war 2009 Anlass zur Gründung einer Arbeitsgruppe Bewegungstherapie in der Deutschen Gesellschaft für Rehabilitationswissenschaft (DGRW). Dadurch sollte eine differenzierte wissenschaftliche Auseinandersetzung gefördert und ein Beitrag zur Sicherung einer qualitativ hochwertigen Bewegungstherapie geleistet werden. Mehr als ein Jahrzehnt nach der Gründung ist die Evidenz für Gesundheitswirkungen körperlicher Aktivität weiter erheblich gewachsen. Es sind zahlreiche nationale und internationale Initiativen zur Stärkung der Bewegungsförderung entstanden. Vor diesem Hintergrund verfolgt dieser Beitrag 2 Zielsetzungen: Erstens soll ein Überblick über bisherige Aktivitäten und Arbeitsschwerpunkte der Arbeitsgruppe Bewegungstherapie gegeben werden, der sich (a) auf die Förderung der Rehabilitationsforschung mit Bewegungsbezug, (b) auf den Austausch zwischen Wissenschaft und Reha-Praxis sowie (c) auf die wissenschaftlich fundierte Qualitätsentwicklung in der Bewegungstherapie bezieht. Zweitens werden darauf aufbauend aktuelle und zukünftige Handlungsbedarfe und Fragestellungen für Forschung und Reha-Praxis aus Sicht der AG Bewegungstherapie formuliert.

Exercise promotion in physiotherapy: A qualitative study providing insights into German physiotherapists' practices and experiences

BACKGROUND

Although exercise promotion is a central task of physiotherapists, there is limited evidence about physiotherapists' experiences with exercise promotion and their promotion practices.

OBJECTIVES

To investigate how physiotherapists working in outpatient settings in Germany promote exercise and to explore their experiences with and views on exercise promotion.

DESIGN

Qualitative study with semi-structured interviews.

METHODS

We conducted qualitative semi-structured interviews with a purposive sample of physiotherapists. Data were analysed following Mayring's content analytical approach using deductive and inductive methods. Physiotherapists' methods of exercise promotion were classified using the behaviour change technique (BCT) taxonomy by Michie and colleagues. Further categories were formed in an inductive manner.

RESULTS

Six female and three male physiotherapists (age: 21-55 years, professional experience: 0.5-31 years) were interviewed. We identified the use of 17 distinct BCTs across the interviews (6-13 per interview), most commonly goal setting (behaviour), instruction on how to perform a behaviour and behavioural practice/rehearsal. Four inductive main categories were formed: "barriers and challenges", "facilitators", "responsibilities" and "dealing with setbacks". Lack of patient interest and motivation was named as a main challenge. While the therapists feel responsible for instructing exercise, not all of them regard it as their role to motivate patients. Resistance or lacking compliance lead therapists to either apply strategies to proceed or quit exercise promotion.

CONCLUSIONS

Our research implies substantial individual differences in exercise promotion between therapists. A more consistent approach, more competencies to support unmotivated patients as well as a clearer definition of physiotherapists' role in exercise promotion might be needed.

The role of physical activity promotion in typical exercise therapy concepts: a latent class analysis based on a national survey in German rehabilitation settings

Purpose: Contemporary multidisciplinary rehabilitation programs include the promotion of physical activity as a central goal. Exercise therapy is an essential element in rehabilitation programs working towards this goal. However, little is known about the role of physical activity promotion in exercise therapy practice in rehabilitation settings. The aim is to identify typical exercise therapy concepts in rehabilitation programs regarding the role of physical activity promotion. Further, we want to assess the representation of physical activity promotion among exercise therapy departments across Germany and in relation to different diagnostic categories.Methods: Heads of 713 exercise therapy departments participated in a nationwide questionnaire-based survey collecting information on therapy goals, contents, and methods. Participating facilities treated health conditions in the areas of cardiology, orthopedics, neurology, oncology, psychosomatics and addiction. We applied factor analyses to identify behavior-oriented goals, contents and methods of exercise therapy concepts and used latent class analyses to categorize typical exercise therapy concepts.Results: Six typical exercise therapy concepts were identified. Two of the classes (together 45% of the departments) emphasized physical activity promotion and used related methods. Other concepts focused primarily on physical functioning and exercise or focused on psychosocial goals and positive experiences with physical activity. Typical exercise therapy concepts are only partially determined by the type of health condition.Conclusions: The dissemination of content and methods for a substantial physical activity promotion in exercise therapy, has so far partly taken place in Germany. The results imply that the different status quo in rehabilitation facilities have to be considered to foster the knowledge exchange between science and practice.Implications for rehabilitationThe results on typical exercise therapy concepts give a structured overview of different priorities with regard to aims, content, and methods of exercise therapy in the light of the International Classification of Functioning, Disability, and Health.The study reveals that the dissemination of theoretically sound, evidence-based concepts for physical activity promotion has reached a half of the institutions in German rehabilitation settings. This national example generally suggests that there is a need for an increased exchange of knowledge between science and practice related to exercise therapy in rehabilitation settings.The results enable practitioners to reflect on their exercise therapy concepts with respect to contemporary exercise therapy concepts that integrate physical activity promotion appropriately.Stakeholders and rehabilitation professionals can use the results to design strategies for quality development, taking into account the different status quo of therapy concepts in the "real world" of rehabilitation practice.The results of the survey provide the basis for a scientifically-based comparison of exercise therapy across countries and health care systems.

Behaviour change techniques applied in interventions to enhance physical activity adherence in patients with chronic musculoskeletal conditions: A systematic review and meta-analysis

OBJECTIVE

To identify Behaviour Change Techniques (BCTs) applied in interventions to enhance physical activity (PA) adherence in patients with chronic musculoskeletal conditions and to investigate the effectiveness of these interventions in increasing PA adherence.

METHODS

A systematic search of seven databases was conducted. We included (cluster/quasi-) randomised controlled trials comparing behaviour change interventions to no/placebo/minimal interventions or usual care and involving at least a three-month post-intervention follow-up. Methodological quality was assessed, study characteristics and BCTs were narratively summarised and a meta-analysis was conducted.

RESULTS

Across 22 included studies, we coded 8-18 BCTs (mean = 11.2) in intervention and 0-12 (mean = 3.5) in control groups. Common BCTs were "graded tasks", "goal setting", "self-monitoring", "problem solving" and "feedback". Meta-analyses of 17 studies revealed a small medium-term effect (3-6 months post-intervention, standardised mean difference (SMD) = 0.20, 95% CI 0.08-0.33) and no long-term effect (7-12 months post-intervention, SMD = 0.13, 95% CI -0.02 to 0.28). Subgroup analysis yielded a higher effect (SMD = 0.29, 95% CI 0.19-0.40) for interventions using a greater number of BCTs.

CONCLUSION

There is moderate quality evidence that interventions using BCTs are effective to enhance medium-term physical activity adherence.

PRACTICE IMPLICATION

While superiority of single BCTs was not shown, it is likely that using more BCTs results in better adherence.

Exercise therapy in medical rehabilitation: Study protocol of a national survey at facility and practitioner level with a mixed method design

BACKGROUND

The importance of physical activity and the orientation of exercise therapy in rehabilitation has changed for many chronic health conditions. Exercise therapy is the most applied therapy form within multidisciplinary rehabilitation programs for almost all chronic health conditions. Despite the scientifically discussed need to refine exercise therapy, there is relatively little knowledge of how exercise therapy is actually conducted. This study protocol describes the methodological procedure used in the project "Exercise therapy in medical rehabilitation: a survey at facility and practitioner level", which aims to take a national survey of exercise therapy in rehabilitation practice in Germany.

METHODS

The project was implemented using an explanatory sequential mixed method design. Quantitative and qualitative methods were integrated in two consecutive project phases. Phase 1 used a standardized, quantitative written survey of the heads of exercise therapy departments to compile a national overview of concepts and process features of exercise therapy of individual rehabilitation facilities. Phase 2 recorded individual perspectives and opinions concerning exercise therapy goals, content and methods and current developments in the rehabilitation context (e.g., physical activity promotion, interdisciplinarity, standardization) of exercise therapy practitioners. Over the course of two one-and-a-half day workshops, central themes were introduced and prepared with standardized written individual surveys from Phase 1 and combined with qualitative surveys using facilitated group discussions (focus groups in mixed methods design).

DISCUSSION

The project generates a comprehensive picture of exercise therapy in medical rehabilitation at facility level and inserts further information at the practitioner level into this context. The chosen methodology of a mixed method design combines the perspective of the facility with that of the practitioner, thus allowing for a complex and multifaceted description of the status quo in exercise therapy practice and makes it possible to identify facilitators and barriers for the refinement of exercise therapy in specific everyday rehabilitation. These findings form the basis for the systematic development of quality exercise therapy in rehabilitation, in particular in terms of the refinement, implementation and dissemination of biopsychosocial concepts of exercise therapy.

[Knee school as a secondary preventive approach : The sustainable treatment of occupational gonarthrosis]

BACKGROUND

2-6 months after successful medical rehabilitation in gonarthrosis, the positive effects remit without the implementation of adequate aftercare strategies.

OBJECTIVES

A prospective comparative study aimed to investigate whether and to what extent the sustainability model of knee school for the secondary preventive treatment of occupational gonarthrosis is able to maintain positive treatment effects in the medium term.

MATERIAL AND METHODS

A total of 292 male employees from the building trade went through the three-week phase 1 of the biopsychosocial knee college with a focus on ergonomics and muscle strength training. In the following 12 months (Phase 2), the participants were contacted several times by telephone in order to motivate them to continue the training. While 178 employees voluntarily and locally continued their training in selected fitness centers with financial support (VG 1), and 38 employees opted for an individual home program (VG 2), 76 participants stopped all training (KG).

RESULTS

After Phase 1, all groups showed significant improvements in the parameters mobility, as well as stretch ability and strength endurance of the thigh muscles, complaints of the knee and quality of life. While the parameters in VG 1 continued to develop positively after 12 months, the measured values in VG 2, with the exception of muscle strength, moderately remitted. By contrast, a significant decline in the measurement values partly below the status quo ante was observed for the KG.

CONCLUSIONS

As part of the aftercare, financially supported training in a fitness center with accompanying regular telephone contacts for male construction workers with knee discomforts shows positive effects if the participation is voluntary. Organized training in the fitness center is superior to individual home programs.

Long-term effects of interprofessional biopsychosocial rehabilitation for adults with chronic non-specific low back pain: a multicentre, quasi-experimental study

BACKGROUND

Improvement of the long-term effectiveness of multidisciplinary ortho-paedic rehabilitation (MOR) in the management of chronic non-specific low back pain (CLBP) remains a central issue for health care in Germany. We developed an interprofessional and interdisciplinary, biopsychosocial rehabilitation concept named "PASTOR" to promote self-management in adults with CLBP and compared its effectiveness with the current model of MOR.

METHODS

A multicentre quasi-experimental study with three measurement time points was implemented. 680 adults aged 18 to 65 with CLBP were assed for eligibil-ity in three inpatient rehabilitation centres in Germany. At first the effects of the MOR, with a total extent of 48 hours (control group), were assessed. Thereafter, PASTOR was implemented and evaluated in the same centres (intervention group). It consisted of six interprofessional modules, which were provided on 12 days in fixed groups, with a total extent of 48 hours. Participants were assessed with self-report measures at baseline, discharge, and 12 months for functional ability (primary outcome) using the Hannover Functional Ability Questionnaire (FFbH-R) and vari-ous secondary outcomes (e.g. pain, health status, physical activity, pain coping, pain-related cognitions).

RESULTS

In total 536 participants were consecutively assigned to PASTOR (n=266) or MOR (n=270). At 12 months, complete data of 368 participants was available. The adjusted between-group difference in the FFbH-R at 12 months was 6.58 (95% CI 3.38 to 9.78) using complete data and 3.56 (95% CI 0.45 to 6.67) using available da-ta, corresponding to significant small-to-medium effect sizes of d=0.42 (p<0.001) and d=0.10 (p=0.025) in favour of PASTOR. Further improvements in secondary out-comes were also observed in favour of PASTOR.

CONCLUSION

The interprofessional and interdisciplinary, biopsychosocial rehabilita-tion program PASTOR shows some improvements of the long-term effectiveness of inpatient rehabilitation in the management of adults with CLBP. Further insights into mechanisms of action of complex intervention programs are required.

Health behaviour change theories: contributions to an ICF-based behavioural exercise therapy for individuals with chronic diseases

PURPOSE

The purpose of this perspective is (1) to incorporate recent psychological health behaviour change (HBC) theories into exercise therapeutic programmes, and (2) to introduce the International Classification of Functioning (ICF)-based concept of a behavioural exercise therapy (BET).

METHODS

Relevant personal modifiable factors of physical activity (PA) were identified based on three recent psychological HBC theories. Following the principles of intervention mapping, a matrix of proximal programme objectives specifies desirable parameter values for each personal factor. As a result of analysing reviews on behavioural techniques and intervention programmes of the German rehabilitation setting, we identified exercise-related techniques that impact the personal determinants. Finally, the techniques were integrated into an ICF-based BET concept.

RESULTS

Individuals' attitudes, skills, emotions, beliefs and knowledge are important personal factors of PA behaviour. BET systematically addresses these personal factors by a systematic combination of adequate exercise contents with related behavioural techniques. The presented 28 intervention techniques serve as a theory-driven "tool box" for designing complex BET programmes to promote PA.

CONCLUSION

The current paper highlights the usefulness of theory-based integrative research in the field of exercise therapy, offers explicit methods and contents for physical therapists to promote PA behaviour, and introduces the ICF-based conceptual idea of a BET. Implications for Rehabilitation Irrespective of the clients' indication, therapeutic exercise programmes should incorporate effective, theory-based approaches to promote physical activity. Central determinants of physical activity behaviour are a number of personal factors: individuals' attitudes, skills, emotions, beliefs and knowledge. Clinicians implementing exercise therapy should set it within a wider theoretical framework including the personal factors that influence physical activity. To increase exercise-adherence and promote long-term physical activity behaviour change, the concept of a behavioural exercise therapy (BET) offers a theory-based approach to systematically address relevant personal factors with a combination of adequate contents of exercise with exercise-related techniques of behaviour change.

[Resource management: ICF-oriented exercise programs for patients with diabetes mellitus type 2. Chronic illnesses and biopsychosocial status]

Common health problems are increasing due to the combination of decreased physical activity demands in everyday life and demographic changes; thus, the importance of exercise therapy is increasing. The incidence and prevalence of today's predominant chronic diseases are directly related to physical activity. However, daily clinical routine does not stay abreast with these changes. The education of physicians, and thus their scope of action, is dominated by biomedical therapy concepts, predominantly drug therapy concepts. Differential and consolidated findings of modern exercise and sport science are astonishingly rare in the counselling and treatment portfolio of medical care. The present disease management program for persons with diabetes mellitus type 2 is a good example. Referring to this background, the authors address the new approach of "ICF-oriented exercise programs and biopsychosocial status." They present resource-related interventional strategies and health care concepts for chronic health disorders like the metabolic syndrome or diabetes mellitus type 2. The relevance and use of active health promotion and care - due to lifestyle- and age-related health problems of the population - will increase in importance and be more commonly recommended.
