Technology-based interprofessional collaboration in primary care for home rehabilitation of the older adults: A dutch exploratory study.

Primary healthcare professionals face an increasing number of geriatrics patients, and patient care often involves different disciplines. eHealth offers opportunities to support interprofessional collaboration (IPC). This exploratory study aimed to gain insight in 1) IPC in community-based rehabilitation, 2) facilitators and barriers for technology-based IPC and 3) technological IPC solutions envisioned by the primary healthcare professionals An focus group with six primary healthcare professionals and a design thinking session with four participants were conducted. Data analysis was based upon an IPC model. Results indicate that facilitators and barriers for IPC can be clustered in three categories: human, organization and technology, and provide some requirements to develop suitable IPC technological solutions Primary healthcare professionals recognise the urgency of working collaboratively. Current barriers are understanding each other's professional vocabulary, engaging the older adults, and using technology within the patient's environment. Further research is needed to integrate IPC components in a technological solution.

Using storytelling methodology to identify barriers and facilitators of sustained physical activity in patients with a chronic disease: a qualitative study.

OBJECTIVES: To identify implicit and more profound barriers and facilitators and involving context elements to accomplish sustained physical activity (PA) in patients with a chronic disease. Understanding these barriers and facilitators may help develop future strategies to be used by healthcare professionals in primary care to support patients with a chronic disease to reach sustained PA. DESIGN AND METHODS: The qualitative, narrative research method storytelling was applied. Perspectives of both patients with a chronic disease (n=12) and involved healthcare professionals (n=11) were collected. Stories were audiotaped and retrieved from the transcriptions. Analysis involved a cyclic process of constant comparison. Main themes were arranged in the theoretical framework of the Capability, Opportunity, Motivation and Behaviour (COM-B) model. PARTICIPANTS: Patients were adults with a chronic disease or at high risk of developing a chronic disease who participated in a PA promoting programme. Eligible healthcare professionals were those involved in these PA promoting programmes in primary care, such as physiotherapists, nurse practitioners or sports consultants. RESULTS: From 176 stories, 62 relevant and unique stories were selected for further analysis. Eleven main themes were identified and afterwards linked to the COM-B model. Trust in one's own capabilities and in the healthcare professional were relevant themes. Also, health literacy and coping with temporary interruption were important capabilities. Important motivators were customised PA, increasing awareness, meaningful activities, exercising in a group and success experiences. Aversion to sports was seen as a barrier. Interprofessional collaboration and prerequisites can be a facilitator or a barrier. CONCLUSIONS: This study provides insight into deeper motivations, barriers and facilitators of sustained PA from both the patients' and healthcare professionals' perspective. Comparing these perspectives revealed different views and beliefs on some themes. Attention for temporary interruptions, aversion to sports and health literacy were identified to be important for sustained PA.

Factors influencing the implementation of Home-Based Stroke Rehabilitation: Professionals' perspective.

BACKGROUND: Stroke has a major impact on survivors and their social environment. Care delivery is advocated to become more client-centered and home-based because of their positive impact on client outcomes. The objective of this study was to explore professionals' perspectives on the provision of Home-Based Stroke Rehabilitation (HBSR) in the Netherlands and on the barriers and facilitators influencing the implementation of HBSR in daily practice. METHODS: Semi-structured focus groups were conducted to explore the perspectives of health and social care professionals involved in stroke rehabilitation. Directed content analysis was performed to analyze the transcripts of recorded conversations. RESULTS: Fourteen professionals participated in focus groups (n = 12) or, if unable to attend, an interview (n = 2). Participants varied in professional backgrounds and roles in treating Dutch clients post stroke. Barriers and facilitators influencing the implementation of HBSR in daily practice were identified in relation to: the innovation, the user, the organization and the socio-political context. Participants reported that HBSR can be efficient and effective to most clients because it facilitates client- and caregiver-centered rehabilitation within the clients' own environment. However, barriers in implementing HBSR were perceived in a lack of (structured) inter-professional collaboration and the transparency of expertise of primary care professionals. Also, the current financial structures for HBSR in the Netherlands are viewed as inappropriate. DISCUSSION: In line with previous studies, we found that HBSR is recognized by professionals as a promising alternative to institution-based rehabilitation for clients with sufficient capabilities (e.g. their own health and informal support). CONCLUSION: Multiple factors influencing the implementation of HBSR were identified. Our study suggests that, in order to implement HBSR in daily practice, region specific implementation strategies need to be developed. We recommend developing strategies concerning: organized and coordinated inter-professional collaboration, transparency of the expertise of primary care professionals, and the financial structures of HBSR.

A Simple Target Interception Task as Test for Activities of Daily Life Performance in Older Adults.

Previous research showed that a simple target interception task reveals differences between younger adults (YA) and older adults (OA) on a large screen under laboratory conditions. Participants intercept downward moving objects while a horizontally moving background creates an illusion of the object moving in the opposite direction of the background. OA are more influenced by this illusory motion than YA. OA seem to be less able to ignore irrelevant sensory information than YA. Since sensory integration relates to the ability to perform Activities of Daily Living (ADL), this interception task can potentially signal ADL issues. Here we investigated whether the results of the target interception task could be replicated using a more portable setup, i.e., a tablet instead of a large touch screen. For YA from the same, homogeneous population, the main effects were replicated although the task was more difficult in the tablet set-up. After establishing the tablet's validity, we analyzed the response patterns of OA that were less fit than the OA in previous research. We identified three different illusion patterns: a (large) illusion effect (indicating over integration), a reverse illusion effect, and no illusion effect. These different patterns are much more nuanced than previously reported for fit OA who only show over integration. We propose that the patterns are caused by differences in the samples of OA (OA in the current sample were older and had lower ADL scores), possibly modulated by increased task difficulty in the tablet setup. We discuss the effects of illusory background motion as a function of ADL scores using a transitional model. The first pattern commences when sensory integration capability starts to decrease, leading to a pattern of over-integration (illusion effect). The second pattern commences when compensatory mechanisms are not sufficient to counteract the effect of the background motion, leading to direction errors in the same direction as the background motion (reverse illusion). The third pattern commences when the task requirements are too high, leading OA to implement a probabilistic strategy by tapping toward the center of the screen.

The effectiveness of functional task exercise and physical therapy as prevention of functional decline in community dwelling older people with complex health problems.

BACKGROUND: A physically active lifestyle in older people contributes to the preservation of good health. We assessed the influence of physiotherapy on daily functioning among community dwelling older people (75+) with complex health problems identified with screening, versus usual care. We also compared functional task exercise (FTE), with problems prioritized by older people, trained in the home environment, versus usual preventive physical therapy (PPT). METHODS: Design: FTE and PPT were compared in a randomized controlled trial (RCT). Both interventions were compared with daily functioning in an observational study: control group. SETTING/PARTICIPANTS: Community-dwelling persons aged ≥75 years with daily activity limitations enlisted in 83 general practices (n = 155). INTERVENTIONS: Both intervention groups (FTE, n = 76 and PPT, n = 79) received individual, 30 min treatments. The control group (n = 228) did not get any experimental intervention offered. MEASUREMENTS: Groningen Activities of Daily Living Restriction Scale (GARS). STATISTICAL ANALYSES: Linear Mixed Model analysis, correcting for age, sex, baseline scores and clustering by physiotherapist were used to compare the different groups. RESULTS: At baseline, 74% percent of the intervention trial group was female vs 79% in the control group. Median ages were 83.9 and 84.7 respectively. The median baseline GARS-score for the control group was 41.0 (25 and 75 percentile): 35.0; 48.0) and 40.0 (25 and 75 percentile: 32.3; 46.0) for the intervention group (FTE + PPT). The mean change over time was 3.3 (2.5; 4.1) for the control group. Mean difference in change over time between the intervention (FTE + PPT) and the control group was - 2.5 (- 4.3; - 0.6) (p = .009). Between FTE and PPT the difference in change was - 0.4 (95% CI: -2.3; 3.0, p = 0.795). CONCLUSION: An exercise intervention led by physiotherapists may slow down decline in self-reported daily functioning in older persons with daily activity limitations, identified by pro-active case finding. TRIAL REGISTRATION: Netherlands trial register ( NTR2407 ). Registered 6th of July 2010.

Evaluation of the wear-and-tear scale for therapeutic footwear, results of a generalizability study.

OBJECTIVE: Therapeutic footwear is often prescribed at considerable cost. Foot-care specialists normally assess the wear-and-tear of therapeutic footwear in order to monitor the adequacy of the prescribed footwear and to gain an indicator of its use. We developed a simple, rapid, easily applicable indicator of wear-and-tear of therapeutic footwear: the wear-and-tear scale. The aim of this study was to investigate the intra- and inter-rater reliability of the wear-and-tear scale. METHODS: A test set of 100 therapeutic shoes was assembled; 24 raters (6 inexperienced and 6 experienced physiatrists, and 6 inexperienced and 6 experienced orthopaedic shoe technicians) rated the degree of wear-and-tear of the shoes on the scale (range 0-100) twice on 1 day with a 4-h interval (short-term) and twice over a 4-week interval (long-term). Generalizability theory was applied for the analysis. RESULTS: Short-term, long-term and overall intra-rater reliability was excellent (coefficients 0.99, 0.99 and 0.98; standard error of measurement (SEM) 2.6, 2.9 and 3.9; smallest detectable changes (SDC) 7.3, 8.0 and 10.8, respectively). Inter-rater reliability between professions, experience and inexperienced raters, and overall was excellent (coefficients 0.97, 0.98 and 0.93; SEM 4.9, 4.5, and 8.1; SDC 13.7, 12.4 and 22.5, respectively). CONCLUSION: The wear-and-tear scale has excellent intra-rater, inter-rater, and overall reliability.

Advantages of virtual reality in the rehabilitation of balance and gait: Systematic review.

BACKGROUND: Virtual reality (VR) has emerged as a therapeutic tool facilitating motor learning for balance and gait rehabilitation. The evidence, however, has not yet resulted in standardized guidelines. The aim of this study was to systematically review the application of VR-based rehabilitation of balance and gait in 6 neurologic cohorts, describing methodologic quality, intervention programs, and reported efficacy. METHODS: This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. VR-based treatments of Parkinson disease, multiple sclerosis, acute and chronic poststroke, traumatic brain injury, and cerebral palsy were researched in PubMed and Scopus, including earliest available records. Therapeutic validity (CONTENT scale) and risk of bias in randomized controlled trials (RCT) (Cochrane Collaboration tool) and non-RCT (Newcastle-Ottawa scale) were assessed. RESULTS: Ninety-seven articles were included, 68 published in 2013 or later. VR improved balance and gait in all cohorts, especially when combined with conventional rehabilitation. Most studies presented poor methodologic quality, lacked a clear rationale for intervention programs, and did not utilize motor learning principles meticulously. RCTs with more robust methodologic designs were widely recommended. CONCLUSION: Our results suggest that VR-based rehabilitation is developing rapidly, has the potential to improve balance and gait in neurologic patients, and brings additional benefits when combined with conventional rehabilitation. This systematic review provides detailed information for developing theory-driven protocols that may assist overcoming the observed lack of argued choices for intervention programs and motor learning implementation and serves as a reference for the design and planning of personalized VR-based treatments.

Aging and Sensitivity to Illusory Target Motion With or Without Secondary Tasks.

Older individuals seem to find it more difficult to ignore inaccurate sensory cues than younger individuals. We examined whether this could be quantified using an interception task. Twenty healthy young adults (age 18-34) and twenty-four healthy older adults (age 60-82) were asked to tap on discs that were moving downwards on a screen with their finger. Moving the background to the left made the discs appear to move more to the right. Moving the background to the right made them appear to move more to the left. The discs disappeared before the finger reached the screen, so participants had to anticipate how the target would continue to move. We examined how misjudging the disc's motion when the background moves influenced tapping. Participants received veridical feedback about their performance, so their sensitivity to the illusory motion indicates to what extent they could ignore the task-irrelevant visual information. We expected older adults to be more sensitive to the illusion than younger adults. To investigate whether sensorimotor or cognitive load would increase this sensitivity, we also asked participants to do the task while standing on foam or counting tones. Background motion influenced older adults more than younger adults. The secondary tasks did not increase the background's influence. Older adults might be more sensitive to the moving background because they find it more difficult to ignore irrelevant sensory information in general, but they may rely more on vision because they have less reliable proprioceptive and vestibular information.

Effects of Aging in Multisensory Integration: A Systematic Review.

Multisensory integration (MSI) is the integration by the brain of environmental information acquired through more than one sense. Accurate MSI has been shown to be a key component of successful aging and to be crucial for processes underlying activities of daily living (ADLs). Problems in MSI could prevent older adults (OA) to age in place and live independently. However, there is a need to know how to assess changes in MSI in individuals. This systematic review provides an overview of tests assessing the effect of age on MSI in the healthy elderly population (aged 60 years and older). A literature search was done in Scopus. Articles from the earliest records available to January 20, 2016, were eligible for inclusion if assessing effects of aging on MSI in the healthy elderly population compared to younger adults (YA). These articles were rated for risk of bias with the Newcastle-Ottawa quality assessment. Out of 307 identified research articles, 49 articles were included for final review, describing 69 tests. The review indicated that OA maximize the use of multiple sources of information in comparison to YA (20 studies). In tasks that require more cognitive function, or when participants need to adapt rapidly to a situation, or when a dual task is added to the experiment, OA have problems selecting and integrating information properly as compared to YA (19 studies). Additionally, irrelevant or wrong information (i.e., distractors) has a greater impact on OA than on YA (21 studies). OA failing to weigh sensory information properly, has not been described in previous reviews. Anatomical changes (i.e., reduction of brain volume and differences of brain areas' recruitment) and information processing changes (i.e., general cognitive slowing, inverse effectiveness, larger time window of integration, deficits in attentional control and increased noise at baseline) can only partly explain the differences between OA and YA regarding MSI. Since we have an interest in successful aging and early detection of MSI issues in the elderly population, the identified tests form a good starting point to develop a clinically useful toolkit to assess MSI in healthy OA.

Therapeutic validity and effectiveness of supervised physical exercise training on exercise capacity in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis.

OBJECTIVE: Our aim was to determine the effectiveness of supervised physical exercise training on exercise capacity in patients with chronic obstructive pulmonary disease taken into consideration indices such as therapeutic validity of interventions, methodological quality of studies, and exercise volume. DATA RESOURCES: MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, and PEDro databases were searched from inception until 17 July 2015 for randomized controlled trials comparing the effect of supervised exercise training vs. usual care in patients with chronic obstructive pulmonary disease. The references of included studies and review articles were hand searched for additional references and key authors of included trials were crosschecked in PubMed for any missed references. REVIEW METHODS: Two reviewers independently assessed therapeutic validity of exercise training and methodological quality of included studies. Overall effects were calculated using a random effects model. RESULTS: A total of 13 studies involving 756 patients with chronic obstructive pulmonary disease were included. Significant differences in maximal exercise capacity (standardized mean difference 0.52, 95% CI 0.31 to 0.74) and endurance exercise capacity (standardized mean difference 0.73, 95% CI 0.50 to 0.96) in favor of physical exercise training were found. The volume of physical exercise per week, the total volume of physical exercise, or their associations did not significantly influence the effect of training. CONCLUSION: Effects of supervised physical exercise was not significantly altered by therapeutic validity. A combination of aerobic exercise and strength training was found to be more effective than strength training or endurance training alone in increasing the 6-minute walking distance.

Validity and usability of low-cost accelerometers for internet-based self-monitoring of physical activity in patients with chronic obstructive pulmonary disease.

BACKGROUND: The importance of regular physical activity for patients with chronic obstructive pulmonary disease (COPD) is well-established. However, many patients do not meet the recommended daily amount. Accelerometers might provide patients with the information needed to increase physical activity in daily life. OBJECTIVE: Our objective was to assess the validity and usability of low-cost Internet-connected accelerometers. Furthermore we explored patients' preferences with regards to the presentation of and feedback on monitored physical activity. METHODS: To assess concurrent validity we conducted a field validation study with patients who wore two low-cost accelerometers, Fitbit and Physical Activity Monitor (PAM), at the same time along with a sophisticated multisensor accelerometer (SenseWear Armband) for 48 hours. Data on energy expenditure assessed from registrations from the two low-cost accelerometers were compared to the well validated SenseWear Armband which served as a reference criterion. Usability was examined in a cross-over study with patients who, in succession, wore the Fitbit and the PAM for 7 consecutive days and filled out a 16 item questionnaire with regards to the use of the corresponding device RESULTS: The agreement between energy expenditure (METs) from the SenseWear Armband with METs estimated by the Fitbit and PAM was good (r=.77) and moderate (r=.41), respectively. The regression model that was developed for the Fitbit explained 92% whereas the PAM-model could explain 89% of total variance in METs measured by the SenseWear. With regards to the usability, both the Fitbit and PAM were well rated on all items. There were no significant differences between the two devices. CONCLUSIONS: The low-cost Fitbit and PAM are valid and usable devices to measure physical activity in patients with COPD. These devices may be useful in long-term interventions aiming at increasing physical activity levels in these patients.

Use and effects of custom-made therapeutic footwear on lower-extremity-related pain and activity limitations in patients with rheumatoid arthritis: A prospective observational study of a cohort.

OBJECTIVES: An estimated 55-90% of patients with rheumatoid arthritis have foot problems. Therapeutic footwear is frequently prescribed as part of usual care, but data on its use and effect is incomplete. This study aimed to investigate the use and effects of therapeutic footwear. METHODS: Patients with rheumatoid arthritis receiving custom-made therapeutic footwear for the first time formed an inception cohort. Patients reported their therapeutic footwear use on 3 consecutive days in activity diaries 14 and 20 weeks after delivery of the footwear. The Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) was used as the primary outcome of lower-extremity-related pain and activity limitations, and the Health Assessment Questionnaire (HAQ) as a secondary outcome measure of activity limitations, both at baseline and 26 weeks after therapeutic footwear delivery. RESULTS: The cohort comprised 114 rheumatoid arthritis patients (median disease duration 10 years). Mean (standard deviation) therapeutic footwear use was 54 (25)% of the time patients were out of bed. The median (interquartile range) WOMAC score improved from 41 (27-59) to 31 (16-45) (p < 0.001). Secondary outcome measures improved significantly. CONCLUSION: Therapeutic footwear was used with moderate intensity by most rheumatoid arthritis patients and was associated with a substantial decrease in pain and activity limitations. Therapeutic footwear is a relevant treatment option for patients with rheumatoid arthritis and foot problems.

Determinants influencing the implementation of home-based stroke rehabilitation: a systematic review.

PURPOSE: Home-based rehabilitation is a promising alternative to regular center-based stroke rehabilitation. The objective of this study was to identify what is currently known about determinants that influence the implementation of home-based stroke rehabilitation (HBSR) in clinical practice. METHODS: A systematic review of determinants of HBSR was conducted, using a framework for innovation (including determinants related to the innovation, the user, the organization, and the socio-political context). Reviews, meta-analyses, and qualitative studies were included. Studies were selected if they concerned: home-based rehabilitation of stroke patient's (motor) function, changes in in-person service delivery (> 24 h to 12 months post-stroke) and determinants of implementation. RESULTS: A total of 88 studies were identified, of which 7 studies met the inclusion criteria. Identified determinants of implementation of HBSR were: intervention effectiveness, the exact nature of the medical condition, satisfaction with services, coordination of services, inter-professional collaborations, availability of appropriate training equipment, and costs. However, none of the studies had the primary aim to identify determinants of implementation. CONCLUSION: A more complete and detailed overview of existing determinants of HBSR is needed to assist professionals and organizations in decision-making on HBSR implementation and development of suitable strategies for implementation. Implications for Rehabilitation Committed professionals and a smooth transfer to the home-environment are essential elements for home-based rehabilitation or early supported discharge. The determinants related to the client include age, needs, stability and severity of the stroke as well as the living conditions. Clients and care givers should be involved in the recovery process including the decision for early discharge and home-based rehabilitation. It is necessary that essential therapy equipment be provided and that the travel times and costs of therapists are reimbursed.

Cognitive treatment of illness perceptions in patients with chronic low back pain: a randomized controlled trial.

BACKGROUND: Illness perceptions have been shown to predict patient activities. Therefore, studies of the effectiveness of a targeted illness-perception intervention on chronic nonspecific low back pain (CLBP) are needed. OBJECTIVE: The purpose of this study was to compare the effectiveness of treatment of illness perceptions against a waiting list for patients with CLBP. DESIGN: This was a prospectively registered randomized controlled trial with an assessor blinded for group allocation. SETTING: The study was conducted in an outpatient rehabilitation clinic. PARTICIPANTS: The participants were 156 patients (18-70 years of age) with CLBP (>3 months). INTERVENTION: Patients were randomly assigned to either a treatment group or to a waiting list (control) group. Trained physical therapists and occupational therapists delivered 10 to 14 one-hour treatment sessions according to the treatment protocol. MEASUREMENTS: The primary outcome measure was change in patient-relevant physical activities (patient-specific complaints questionnaire). The secondary outcome measures were changes in illness perceptions (illness perceptions questionnaire) and generic physical activity level (quebec back pain disability scale). Measurements were taken at baseline (0 weeks) and after treatment (18 weeks). RESULTS: A baseline-adjusted analysis of covariance showed that there were statistically significant differences between intervention and control groups at 18 weeks for the change in patient-relevant physical activities. This was a clinically relevant change (19.1 mm) for the intervention group. Statistically significant differences were found for the majority of illness perception scales. There were no significant differences in generic physical activity levels. LIMITATIONS: Longer-term effectiveness was not studied. CONCLUSIONS: This first trial evaluating cognitive treatment of illness perceptions concerning CLBP showed statistically significant and clinically relevant improvements in patient-relevant physical activities at 18 weeks.

The implementation of the functional task exercise programme for elderly people living at home.

BACKGROUND: The Functional Task Exercise programme is an evidence-based exercise programme for elderly people living at home. It enhances physical capacity with sustainable effects. FTE is provided by physiotherapists and remedial therapists. Although the intervention was found to be effective in a Randomised Controlled Trial, we may not assume that therapists will automatically supply the programme or that elderly people will automatically join the programme. This study protocol focuses on identifying determinants of implementation, developing implementation strategies and studying the effects of the implementation in daily practice. METHODS/DESIGN: Phase 1: The systematic identification of determinants of the implementation of FTE among therapists and the elderly. A questionnaire study was conducted in a random sample of 100 therapists, and interviews took place with 23 therapists and 8 elderly people (aged 66 to 80 years). The determinants were broken down into four categories: the characteristics of the environment, the organisation, the therapists, and the training programme.Phase 2: Developing and applying strategies adapted to the determinants identified. Fifteen physiotherapists will be trained to provide FTE and to recruit elderly people living at home. The therapists will then deliver the 12-week programme to two groups of elderly, each consisting of six to twelve people aged 70 years or older.Phase 3: Study of implementation and the impact. To study the actual use of FTE: 1) therapists record information about the selection of participants and how they apply the key features of FTE, 2) the participating elderly will keep an exercise logbook, 3) telephone interviews will take place with the therapists and the elderly and there will be on-site visits. The effects on the elderly people will be studied using: 1) the Patient-Specific Questionnaire, the Timed Up and Go test and a two performance tests. All tests will be performed at the start of the FTE programme, half way through, and at the end of the programme. DISCUSSION: The number of older people will increase in many countries in the years to come and so the project outcomes will be of interest to policy-makers, insurance companies, health-care professionals and implementation researchers.

Therapeutic validity and effectiveness of preoperative exercise on functional recovery after joint replacement: a systematic review and meta-analysis.

BACKGROUND: Our aim was to develop a rating scale to assess the therapeutic validity of therapeutic exercise programmes. By use of this rating scale we investigated the therapeutic validity of therapeutic exercise in patients awaiting primary total joint replacement (TJR). Finally, we studied the association between therapeutic validity of preoperative therapeutic exercise and its effectiveness in terms of postoperative functional recovery. METHODS: (Quasi) randomised clinical trials on preoperative therapeutic exercise in adults awaiting TJR on postoperative recovery of functioning within three months after surgery were identified through database and reference screening. Two reviewers extracted data and assessed the risk of bias and therapeutic validity. Therapeutic validity of the interventions was assessed with a nine-itemed, expert-based rating scale (scores range from 0 to 9; score ≥6 reflecting therapeutic validity), developed in a four-round Delphi study. Effects were pooled using a random-effects model and meta-regression was used to study the influence of therapeutic validity. RESULTS: Of the 7,492 articles retrieved, 12 studies (737 patients) were included. None of the included studies demonstrated therapeutic validity and two demonstrated low risk of bias. Therapeutic exercise was not associated with 1) observed functional recovery during the hospital stay (Standardised Mean Difference [SMD]: -1.19; 95%-confidence interval [CI], -2.46 to 0.08); 2) observed recovery within three months of surgery (SMD: -0.15; 95%-CI, -0.42 to 0.12); and 3) self-reported recovery within three months of surgery (SMD -0.07; 95%-CI, -0.35 to 0.21) compared with control participants. Meta-regression showed no statistically significant relationship between therapeutic validity and pooled-effects. CONCLUSION: Preoperative therapeutic exercise for TJR did not demonstrate beneficial effects on postoperative functional recovery. However, poor therapeutic validity of the therapeutic exercise programmes may have hampered potentially beneficial effects, since none of the studies met the predetermined quality criteria. Future review studies on therapeutic exercise should address therapeutic validity.

Overlap of cognitive concepts in chronic widespread pain: an exploratory study.

BACKGROUND: A wide variety of cognitive concepts have been shown to play an important role in chronic widespread pain (CWP). Although these concepts are generally considered to be distinct entities, some might in fact be highly overlapping. The objectives of this study were to (i) to establish inter-relationships between self-efficacy, cognitive coping styles, fear-avoidance cognitions and illness beliefs in patients with CWP and (ii) to explore the possibility of a reduction of these cognitions into a more limited number of domains. METHODS: Baseline measurement data of a prospective cohort study of 138 patients with CWP were used. Factor analysis was used to study the associations between 16 different cognitive concepts. RESULTS: Factor analysis resulted in three factors: 1) negative emotional cognitions, 2) active cognitive coping, and 3) control beliefs and expectations of chronicity. CONCLUSION: Negative emotional cognitions, active cognitive coping, control beliefs and expectations of chronicity seem to constitute principal domains of cognitive processes in CWP. These findings contribute to the understanding of overlap and uniqueness of cognitive concepts in chronic widespread pain.

Best candidates for cognitive treatment of illness perceptions in chronic low back pain: results of a theory-driven predictor study.

OBJECTIVE: The aim of this study was to identify treatment-specific predictors of the effectiveness of a method of evidence-based treatment: cognitive treatment of illness perceptions. This study focuses on what treatment works for whom, whereas most prognostic studies focusing on chronic non-specific low back pain rehabilitation aim to reduce the heterogeneity of the population of patients who are suitable for rehabilitation treatment in general. DESIGN: Three treatment-specific predictors were studied in patients with chronic non-specific low back pain receiving cognitive treatment of illness perceptions: a rational approach to problem-solving, discussion skills and verbal skills. Hierarchical linear regression analysis was used to assess their predictive value. Short-term changes in physical activity, measured with the Patient-Specific Functioning List, were the outcome measure for cognitive treatment of illness perceptions effect. RESULTS: A total of 156 patients with chronic non-specific low back pain participated in the study. Rational problem-solving was found to be a significant predictor for the change in physical activity. Discussion skills and verbal skills were non-significant. Rational problem-solving explained 3.9% of the total variance. CONCLUSION: The rational problem-solving scale results are encouraging, because chronic non-specific low back pain problems are complex by nature and can be influenced by a variety of factors. A minimum score of 44 points on the rational problem-solving scale may assist clinicians in selecting the most appropriate candidates for cognitive treatment of illness perceptions.

Benefits of treatment theory in the design of explanatory trials: cognitive treatment of illness perception in chronic low back pain rehabilitation as an illustrative example.

BACKGROUND: Evidence-based treatment is not effective for all patients. Research must therefore be carried out to help clinicians to decide for whom and under what circumstances certain treatment is effective. Treatment theory can assist in designing research that will provide results on which clinical decision-making can be based. OBJECTIVE: To illustrate how treatment theory can be helpful in the design of explanatory trials that assist clinical decision-making. METHODS: The benefit of treatment theory was demonstrated by approaching the design of a clinical trial from two perspectives: one without the use of treatment theory and one with the explicit use of treatment theory. Evaluation of the effectiveness of cognitive treatment of illness perceptions for patients with chronic low back pain was used as an illustrative example. ISSUES: With treatment theory as the main focus, the intervention became the starting point for the design of an explanatory trial. Potentially relevant patient selection criteria, essential treatment components, the optimal choice of a control group and the selection of outcome measures were specified. CONCLUSION: This paper not only describes problems encountered in research on the effectiveness of treatment, but also ways in which to address these problems.

The benefits of theory for clinical practice: cognitive treatment for chronic low back pain patients as an illustrative example.

PURPOSE: To demonstrate, with the help of an example of cognitive treatment for patients with chronic low back pain, how a systematic description of the content and theoretical underpinnings of treatment can help to improve clinical practice. METHODS: A conceptual analysis, two types of theories, and a programme-theory framework were instrumental in systematically specifying the content of the treatment and the underlying assumptions. RESULTS: A detailed description of the cognitive treatment, including: (i) The intended outcomes; (ii) the related treatment components; (iii) the therapeutic process that is expected to mediate between outcomes and components, (iv) the conditions for optimal application; and (v) the guiding principles. CONCLUSIONS: The systematic description of the treatment revealed important issues for clinical practice, such as the patient and therapist characteristics that are needed for optimal provision of cognitive treatment. The discussions on the role of theory in rehabilitation practice are taken one step further in this clinical commentary: instead of simply describing the problems, we also demonstrated a means to tackle them.
