Co-design of a walking activity intervention for stroke survivors.

Introduction: Stroke survivors may not maintain gains made in gait performance after task-oriented circuit training. Behavior change interventions may enhance the long-term adoption of physical activity. This study uses a co-design methodology to develop an intervention and tools to facilitate physical and exercise therapists in supporting an active lifestyle in stroke survivors, which is defined as a lifestyle that integrates daily walking performance with day-to-day activity. Objectives: (1) To describe the insights generated during the co-design process; and (2) To describe the tools that were developed during the co-design process. Methods: A multidisciplinary team consisting of staff members of the Royal Dutch Society for Physical Therapy, exercise and physical therapists specializing in neurorehabilitation and conducting task-oriented circuit class training in primary care settings or day therapy centers within residential care facilities, stroke survivors and their carers, experts in measuring movement behavior in stroke survivors, a company specializing in manufacturing sensors and related software, behavior change specialists, and co-designers all collaborated in a three-stage (define, develop, and deliver) co-design process. Results: In the design process, the team iteratively developed a prototype accelerometer system for measuring walking performance with a feedback function for stroke survivors and their therapists and a prototype toolbox for therapists to support the facilitation of behavior change in their stroke survivors. Discussion: This study shows how co-design can be applied to develop interventions for stroke survivors. Both the prototype system for measuring walking performance and the toolbox incorporate behavior change techniques to support a more physically active lifestyle in stroke survivors. Further research will investigate the feasibility of the intervention.

Illness perceptions; exploring mediators and/or moderators in disabling persistent low back pain. Multiple baseline single-case experimental design.

INTRODUCTION: Illness Perceptions (IPs) may play a role in the management of persistent low back pain. The mediation and/or moderation effect of IPs on primary outcomes in physiotherapy treatment is unknown. METHODS: A multiple single-case experimental design, using a matched care physiotherapy intervention, with three phases (phases A-B-A') was used including a 3 month follow up (phase A'). Primary outcomes: pain intensity, physical functioning and pain interference in daily life. Analyzes: linear mixed models, adjusted for fear of movement, catastrophizing, avoidance, sombreness and sleep. RESULTS: Nine patients were included by six different primary care physiotherapists. Repeated measures on 196 data points showed that IPs Consequences, Personal control, Identity, Concern and Emotional response had a mediation effect on all three primary outcomes. The IP Personal control acted as a moderator for all primary outcomes, with clinically relevant improvements at 3 month follow up. CONCLUSION: Our study might indicate that some IPs have a mediating or a moderating effect on the outcome of a matched care physiotherapy treatment. Assessing Personal control at baseline, as a relevant moderator for the outcome prognosis of successful physiotherapy management of persistent low back pain, should be further eplored.

Physiotherapists' knowledge, attitude and practice behavior to prevent chronification in patients with non-specific, non-traumatic, acute- and subacute neck pain: A qualitative study.

BACKGROUND: The purpose of this study was to explore physiotherapists' knowledge, attitude, and practice behavior in assessing and managing patients with non-specific, non-traumatic, acute- and subacute neck pain, with a focus on prognostic factors for chronification. METHOD: A qualitative study using in-depth semi-structured interviews was conducted with 13 physiotherapists working in primary care. A purposive sampling method served to seek the broadest perspectives. The knowledge-attitude and practice framework was used as an analytic lens throughout the process. Textual data were analyzed using qualitative content analysis with an inductive approach and constant comparison. RESULTS: Seven main themes emerged from the data; physiotherapists self-estimated knowledge and attitude, role clarity, therapeutic relationship, internal- and external barriers to practice behavior, physiotherapists' practice behaviors, and self-reflection. These findings are presented in an adjusted knowledge-attitude and practice behavior framework. CONCLUSION: A complex relationship was found between a physiotherapist's knowledge about, attitude, and practice behavior concerning the diagnostic process and interventions for non-specific, non-traumatic, acute, and subacute neck pain. Overall, physiotherapists used a biopsychosocial view of patients with non-specific neck pain. Physiotherapists' practice behaviors was influenced by individual attitudes towards their professional role and therapeutic relationship with the patient, and individual knowledge and skills, personal routines and habits, the feeling of powerlessness to modify patients' external factors, and patients' lack of willingness to a biopsychosocial approach influenced physiotherapists' clinical decisions. In addition, we found self-reflection to have an essential role in developing self-estimated knowledge and change in attitude towards their therapeutic role and therapist-patient relationship.

Living systematic reviews in rehabilitation science can improve evidence-based healthcare.

Although systematic reviews are considered as central components in evidence-based practice, they currently face an important challenge to keep up with the exponential publication rate of clinical trials. After initial publication, only a minority of the systematic reviews are updated, and it often takes multiple years before these results become accessible. Consequently, many systematic reviews are not up to date, thereby increasing the time-gap between research findings and clinical practice. A potential solution is offered by a living systematic reviews approach. These types of studies are characterized by a workflow of continuous updates which decreases the time it takes to disseminate new findings. Although living systematic reviews are specifically designed to continuously synthesize new evidence in rapidly emerging topics, they have also considerable potential in slower developing domains, such as rehabilitation science. In this commentary, we outline the rationale and required steps to transition a regular systematic review into a living systematic review. We also propose a workflow that is designed for rehabilitation science.

Limited predictive value of illness perceptions for short-term poor recovery in musculoskeletal pain. A multi-center longitudinal study.

BACKGROUND: Musculoskeletal pain (MSP) is recognized worldwide as a major cause of increased years lived with disability. In addition to known generic prognostic factors, illness perceptions (IPs) may have predictive value for poor recovery in MSP. We were interested in the added predictive value of baseline IPs, over and above the known generic prognostic factors, on clinical recovery from MSP. Also, it is hypothesized there may be overlap between IPs and domains covered by the Four-Dimensional Symptom Questionnaire (4DSQ), measuring distress, depression, anxiety and somatization. The aim of this study is twofold; 1) to assess the added predictive value of IPs for poor recovery and 2) to assess differences in predictive value for poor recovery between the Brief Illness Perception Questionnaire - Dutch Language Version (Brief IPQ-DLV) and the 4DSQ. METHODS: An eligible sample of 251 patients with musculoskeletal pain attending outpatient physical therapy were included in a multi-center longitudinal cohort study. Pain intensity, physical functioning and Global Perceived Effect were the primary outcomes. Hierarchical logistic regression models were used to assess the added value of baseline IPs for predicting poor recovery. To investigate the performance of the models, the levels of calibration (Hosmer-Lemeshov test) and discrimination (Area under the Curve (AUC)) were assessed. RESULTS: Baseline 'Treatment Control' added little predictive value for poor recovery in pain intensity [Odds Ratio (OR) 0.80 (Confidence Interval (CI) 0.66-0.97), increase in AUC 2%] and global perceived effect [OR 0.78 (CI 0.65-0.93), increase in AUC 3%]. Baseline 'Timeline' added little predictive value for poor recovery in physical functioning [OR 1.16 (CI 1.03-1.30), increase in AUC 2%]. There was a non-significant difference between AUCs in predictive value for poor recovery between the Brief IPQ-DLV and the 4DSQ. CONCLUSIONS: Based on the findings of this explorative study, assessing baseline IPs, over and above the known generic prognostic factors, does not result in a substantial improvement in the prediction of poor recovery. Also, no recommendations can be given for preferring either the 4DSQ or the Brief IPQ-DLV to assess psychological factors.

Extended steep ramp test normative values for 19-24-year-old healthy active young adults.

PURPOSE: To extend currently available sex and age-specific normative values in children and adolescents for the peak work rate (WRpeak) attained at the steep ramp test (SRT) to healthy active young adults. METHODS: Healthy male and female participants aged between 19 and 24 years were recruited. After screening and anthropometric measurements, participants performed a SRT on a cycle ergometer (increments of 25 W/10 s), monitoring and recording SRT-WRpeak, heart rate (HR), and blood pressure (BP) at rest and directly after peak exercise. RESULTS: Fifty-seven participants (31 males and 26 females; median age of 21.3 years) volunteered and were tested. Anthropometrics, resting BP and lung function were all within normal ranges. Ninety-three percent of the participants attained a peak HR (HRpeak) > 80% of predicted (mean HRpeak 87 ± 5% of predicted). No differences were found in resting and peak exercise variables between females and males, except for absolute SRT-WRpeak (350 W [Q1: 306; Q3: 371] and 487 W [Q1: 450; Q3: 517], respectively) and SRT-WRpeak normalized for body mass (relative SRT-WRpeak; 5.4 ± 0.5 and 6.2 ± 0.6 W/kg, respectively). Low-to-moderate correlations (ρ [0.02-0.71]) were observed between SRT-WRpeak and anthropometric variables for females and males separately. Extended reference curves (8-24-year-old subjects) for SRT performance show different trends between male and female subjects when modelled against age, body height, and body mass. CONCLUSIONS: The present study provides sex-, age-, body height-, and body mass-related normative values (presented as reference centiles) for absolute and relative SRT performance throughout childhood and early adulthood.

Illness perceptions associated with patient burden with musculoskeletal pain in outpatient physical therapy practice, a cross-sectional study.

INTRODUCTION: Musculoskeletal pain (MSP) is a burden to patients and to society. In addition to well-known prognostic factors, illness perceptions (IPs) may be associated with pain intensity and physical functioning in MSP but their role is not fully understood. Our research focused on these questions: 1) Do IPs differ between patients with acute, sub-acute and persistent MSP 2) Are IPs, in addition to well-known prognostic factors, associated with pain intensity and with limitations in physical functioning? METHODS: Eligible MSP patients from 29 physical therapy practices were invited to participate in a cross-sectional study. IPs were measured with the Brief IPQ-DLV. We compared IPs between patients with acute, sub-acute and persistent MSP (1-way ANOVA with Tukey post-hoc tests). Secondly, associations between IPs with pain intensity and physical functioning were assessed (multiple linear regression). RESULTS: With 658 participants, most IP dimensions showed small differences between acute, sub-acute or persistent pain. For pain intensity, the IP dimensions Consequences, Identity and Comprehensibility explained an additional 13.3% of the variance. For physical functioning, the dimensions Consequences, Treatment Control, Identity and Concern explained an additional 26.5% of the variance. DISCUSSION/CONCLUSION: Most IP dimensions showed small differences between acute, sub-acute or persistent pain. In addition to some well-known prognostic variables, higher scores on some IP dimensions are associated with higher pain intensity and more limitations in physical functioning in patients with MSP. Longitudinal studies are needed to explore the longitudinal associations.

Patient education and health literacy.

INTRODUCTION: Patient education is a relatively new science within the field of health care. In the past it consisted mainly of the transfer of knowledge and mostly biomedically based advice. Research has shown this to not be effective and sometimes counterproductive. As health care has moved away from applying a traditional paternalistic approach of 'doctor knows best' to a patient-centred care approach, patient education must be tailored to meet persons' individual needs. PURPOSE: The purpose of this master paper is to increase awareness of patients' health literacy levels. Health literacy is linked to literacy and entails people's knowledge, motivation and competences to access, understand, appraise and apply health information in order to make judgements and take decisions in everyday life concerning health care, disease prevention and health promotion to maintain or improve quality of life during the life course. Many patients have low health literacy skills, and have difficulty with reading, writing, numeracy, communication, and, increasingly, the use of electronic technology, which impede access to and understanding of health care information. IMPLICATIONS: Multiple professional organizations recommend using universal health literacy precautions to provide understandable and accessible information to all patients, regardless of their literacy or education levels. This includes avoiding medical jargon, breaking down information or instructions into small concrete steps, limiting the focus of a visit to three key points or tasks, and assessing for comprehension by using the teach back cycle. Printed information should be written at or below sixth-grade reading level. Visual aids can enhance patient understanding.

The effectiveness of generic self-management interventions for patients with chronic musculoskeletal pain on physical function, self-efficacy, pain intensity and physical activity: A systematic review and meta-analysis.

Generic self-management programs aim to facilitate behavioural adjustment and therefore have considerable potential for patients with chronic musculoskeletal pain. Our main objective was to collect and synthesize all data on the effectiveness of generic self-management interventions for patients with chronic musculoskeletal pain in terms of physical function, self-efficacy, pain intensity and physical activity. Our secondary objective was to describe the content of these interventions, by means of classification according to the Behaviour Change Technique Taxonomy. We searched PubMed, CENTRAL, Embase and Psycinfo for eligible studies. Study selection, data extraction and risk of bias were assessed by two researchers independently. Meta-analyses were only performed if the studies were sufficiently homogeneous and GRADE was used to determine the quality of evidence. We identified 20 randomized controlled trials that compared a self-management intervention to any type of control group. For post-intervention results, there was moderate quality evidence of a statistically significant but clinically unimportant effect for physical function and pain intensity, both favouring the self-management group. At follow-up, there was moderate quality evidence of a small clinically insignificant effect for self-efficacy, favouring the self-management group. All other comparisons did not indicate an effect. Classification of the behaviour change techniques showed large heterogeneity across studies. These results indicate that generic self-management interventions have a marginal benefit for patients with chronic musculoskeletal pain in the short-term for physical function and pain intensity and for self-efficacy in the long-term, and vary considerably with respect to intervention content. SIGNIFICANCE: This study contributes to a growing body of evidence that generic self-management interventions have limited effectiveness for patients with chronic musculoskeletal pain. Furthermore, this study has identified substantial differences in both content and delivery mode across self-management interventions.

The implementation of multiple lifestyle interventions in two organizations: a process evaluation.

OBJECTIVE: To evaluate the implementation of a multicomponent lifestyle intervention at two different worksites. METHODS: Data on eight process components were collected by means of questionnaires and interviews. Data on the effectiveness were collected using questionnaires. RESULTS: The program was implemented partly as planned, and 84.0% (max 25) and 85.7% (max 14) of all planned interventions were delivered at the university and hospital, respectively. Employees showed high reach (96.6%) and overall participation (75.1%) but moderate overall satisfaction rates (6.8 ± 1.1). Significant intervention effects were found for days of fruit consumption (ß = 0.44 days/week, 95% CI: 0.02 to 0.85) in favor of the intervention group. CONCLUSIONS: The study showed successful reach, dose, and maintenance but moderate fidelity and satisfaction. Mainly relatively simple and easily implemented interventions were chosen, which were effective only in improving employees' days of fruit consumption.

Different anthropometric adiposity measures and their association with cardiovascular disease risk factors: a meta-analysis.

OBJECTIVES: To investigate which anthropometric adiposity measure has the strongest association with cardiovascular disease (CVD) risk factors in Caucasian men and women without a history of CVD. DESIGN: Systematic review and meta-analysis. METHODS: We searched databases for studies reporting correlations between anthropometric adiposity measures and CVD risk factors in Caucasian subjects without a history of CVD. Body mass index (BMI), waist circumference, waist-to-hip ratio, waist-to-height ratio and body fat percentage were considered the anthropometric adiposity measures. Primary CVD risk factors were: systolic blood pressure, diastolic blood pressure, high density lipoprotein (HDL) cholesterol, triglycerides and fasting glucose. Two independent reviewers performed abstract, full text and data selection. RESULTS: Twenty articles were included describing 21,618 males and 24,139 females. Waist circumference had the strongest correlation with all CVD risk factors for both men and women, except for HDL and LDL in men. When comparing BMI with waist circumference, the latter showed significantly better correlations to CVD risk factors, except for diastolic blood pressure in women and HDL and total cholesterol in men. CONCLUSIONS: We recommend the use of waist circumference in clinical and research studies above other anthropometric adiposity measures, especially compared with BMI, when evaluating CVD risk factors.

The dangers of inactivity; exercise and inactivity physiology for the manual therapist.

Physiotherapists should take a primary role in relation to the prevention and management of all diseases that are associated with low levels of physical activity. The benefits of regular physical activity on health, longevity, and well being easily surpass the effectiveness of any drugs or other medical treatment. Physical activity has many beneficial effects on the body, helps prevent the development of many chronic diseases and is a useful complement to drug treatment in many diseases. As the importance of physical activity for health might well be underrated and undervalued even by manual therapists we describe the physiological consequences and health dangers of being inactive in this paper.

The effect of physical exercise on cancer-related fatigue during cancer treatment: a meta-analysis of randomised controlled trials.

The aim of this meta-analysis was to evaluate the effects of different exercise prescription parameters during cancer treatment on cancer-related fatigue (CRF). We also aimed to gain insight into the safety and feasibility of exercise during adjuvant cancer treatment. A systematic search of CINAHL, Cochrane Library, Embase, Medline, Scopus and PEDro was carried out. Randomised controlled trials studying the effects of exercise during cancer treatment on CRF were included. In total, 18 studies (12 in breast, four in prostate and two in other cancer patients) met all the inclusion criteria. During breast cancer treatment, home-based exercise lead to a small, non-significant reduction (standardised mean difference 0.10, 95% confidence interval -0.25 to 0.45), whereas supervised aerobic exercise showed a medium, significant reduction in CRF (standardised mean difference 0.30, 95% confidence interval 0.09 to 0.51) compared with no exercise. A subgroup analysis of home-based (n=65) and supervised aerobic (n=98) and resistance exercise programmes (n=208) in prostate cancer patients showed no significant reduction in CRF in favour of the exercise group. Adherence ranged from 39% of the patients who visited at least 70% of the supervised exercise sessions to 100% completion of a home-based walking programme. In more than half the studies (12 of 18; 67%) adverse events were reported. Eight events in total (0.72%) occurred in these studies.

Workload demand in police officers during mountain bike patrols.

To the authors' knowledge this is the first paper that has used the training impulse (TRIMP) 'methodology' to calculate workload demand. It is believed that this is a promising method to calculate workload in a range of professions in order to understand the relationship between work demands and aerobic fitness. The aim of this study was to assess workload demand in police officers from the Utrecht police department in the Netherlands, during patrol by mountain bike. Maximum oxygen intake, maximum heart rate (HRmax), ventilatory threshold (VT)1 and VT2 were determined with a maximal exercise test on a bicycle ergometer. Heart rates were registered throughout three shifts in 20 subjects using a heart rate monitor. Exercise intensity was divided into three phases: phase I (between 40% of HRmax and VT1); phase II (between VT and the respiratory compensation point (RCP)); and phase III (>RCP). The total TRIMP score was obtained by summating the results of the three phases. Average daily workload demands of 355 TRIMPs per day and 1777 TRIMPs per week were measured. Workload demand approached and in some cases exceeded the upper limit of 2000 TRIMPs per week threshold level for physiological stress demands in professional male cyclists.

Upper limb lymphedema 27 (ULL27): Dutch translation and validation of an illness-specific health-related quality of life questionnaire for patients with upper limb lymphedema.

The health-related quality of life questionnaire for lymphedema of the upper limb (ULL27) was translated into Dutch according to international guidelines and validated. Eighty-four patients with lymphedema that occurred after axillary surgery for breast cancer and subsequent radiotherapy, chemotherapy, or hormonal therapy, completed the translated version of the ULL27 and the RAND36. Severity of upper limb edema was measured by specialized physiotherapists. The internal consistency of the domains of the questionnaire was good as were the convergent validity and discriminant ability. Upper limb volume and the domains of the ULL27 were not correlated. The Dutch translation of the ULL27 questionnaire has good internal consistency and validity but further research is needed to determine its responsiveness.

Eccentric overload training in patients with chronic Achilles tendinopathy: a systematic review.

BACKGROUND: Eccentric overload training seems to be a promising conservative intervention in patients with chronic Achilles tendinopathy. The efficacy of eccentric overload training on the outcome measures of pain and physical functioning are not exactly clear. STUDY DESIGN: Systematic review of the literature. METHODS: Electronic databases were searched for randomised clinical trials concerning eccentric overload training in patients with chronic Achilles tendinopathy. The Delphi list was used to assess the methodological quality of the studies. RESULTS: Nine clinical trials were included. Only one study had sufficient methodological quality. The included trials showed an improvement in pain after eccentric overload training. Because of the methodological shortcomings of the trials, no definite conclusion can be drawn concerning the effects of eccentric overload training in patients with chronic Achilles tendinopathy. CONCLUSION: The effects of eccentric exercise training in patients with chronic Achilles tendinopathy on pain are promising; however, the magnitude of the effects cannot be determined. Large, methodologically sound studies from multiple sites in which functional outcome measures are included are warranted.

Relative contribution of mental health and exercise-related pain increment to treadmill test intolerance in patients with chronic low back pain.

STUDY DESIGN: A cross-sectional study. OBJECTIVES: To determine the relative contribution of pain increase and mental health to testing performance during a single bout of exercise in patients with chronic low back pain. BACKGROUND: Controversy exists as to which factors principally limit physical performance in patients with chronic low back pain. Some believe psychological factors limit physical performance, whereas others believe activity-related increases in pain intensity limit performance. METHODS: Seventy-five patients with chronic low back pain reported pain intensity before and after undergoing a maximal, symptom-limited modified treadmill test. Walking time (in minutes) and aerobic fitness were measured. The Short Form 36 Health Survey was administered to all patients. RESULTS: Fifty-four percent of the sample stopped testing because of a significant increase in pain intensity (P = 0.0001). Treadmill performance was lower in patients who stopped because of pain than in those who stopped because of fatigue (P = 0.02). The patients who stopped because of pain were also more likely to have low mental health as assessed by the Short Form 36 Health Survey. Low mental health, however, did not have a statistically significant influence on treadmill performance. CONCLUSION: The data indicate that impairment of physical performance during treadmill testing in patients with chronic low back pain is attributable to testing-induced increase in pain intensity rather than to individual low mental health scores.

Deconditioning in patients with chronic low back pain: fact or fiction?

STUDY DESIGN: Prospective case series with historical controls (normative data). OBJECTIVES: To compare aerobic fitness levels in patients with chronic low back pain with those published on a sample of 295 healthy subjects. SUMMARY OF BACKGROUND DATA: Clinical belief holds that patients with chronic low back pain have low fitness levels as a result of inactivity because of pain. Because few studies have investigated the level of aerobic fitness in these patients, however, it remains unclear how fitness levels in patients with chronic low back pain patients compare with those published a sample of the normative population. METHODS: A sample of 50 patients with chronic low back pain with a mean pain duration of 40 months referred to an outpatient pain clinic performed a symptom-limited modified treadmill test. Aerobic fitness levels were determined by indirect calorimetry to measure oxygen consumption (VO2). Predicted maximum oxygen consumption (VO2max) levels were calculated for all subjects. Multiple regression analysis with adjustment for age and sex yielded prediction equations for men and women separately. Ninety-five percent confidence intervals were calculated for predicted mean oxygen consumption (VO2) and the slope of the equations. These were compared to established prediction equations on healthy subjects. RESULTS: Prediction equations for estimated maximum oxygen consumption (VO2max) in patients with chronic low back pain equal those in healthy sedentary men and active women. CONCLUSIONS: Levels of aerobic fitness in patients with chronic low back pain are comparable with those in healthy subjects.

Aerobic fitness testing in patients with chronic low back pain: which test is best?

STUDY DESIGN: This is a randomized comparison of three exercise tests in a sample of 30 patients with chronic low back pain. OBJECTIVES: To determine, by comparing three exercise tests, which test yields the highest peak and predicted oxygen consumption in a sample of patients with chronic low back pain. SUMMARY OF BACKGROUND DATA: Little is known about the level of aerobic fitness in patients with chronic low back pain, although many rehabilitation programs emphasize aerobic exercise as an important part of their therapy. Measurement of aerobic fitness levels in these patients remains a problem. In healthy individuals, the highest oxygen consumption values come from exercise tests that use the largest muscle groups. For a number of reasons, this may not be true in patients with chronic low back pain. METHODS: In this study, 30 participants with chronic low back pain performed three symptom-limited maximal exercise tests: a treadmill, an upper extremity ergometer, and a bicycle ergometer. The tests were administered in randomized order. Heart rate was continuously monitored and oxygen consumption in terms of mL/kg/minute was measured by indirect calorimetry each 30 seconds. RESULTS: The statistical difference among the tests was highly significant (P < 0.0001). The treadmill test yielded the highest peak and predicted oxygen consumption followed by the bicycle and the upper extremity ergometer test, respectively. CONCLUSIONS: The treadmill test is the best test for measuring aerobic fitness levels in patients with chronic low back pain. It yielded the highest peak oxygen consumption compared with the other tests, coming closest to measuring maximal oxygen consumption.
