Minimal clinically important differenceof fatigue severity scale in patients with chronic stroke

BackgroundOne of the most prevalent symptoms of stroke is fatigue. Fatigue severity scale is the most often used tool for evaluating fatigue in stroke patients, its minimal clinically important difference threshold has not been determined. This study aimed to identify the minimal clinically important difference of fatigue severity scale in stroke patients. MethodsAll study participants were examined using fatigue severity scale and multidimensional fatigue symptom inventory-short form before and after the intervention. The 6-week intervention combined graded activity training and pacing therapy employed to reduce fatigue severity. Participants reported changes in their fatigue severity after the intervention with the global rating of change and visual analog scale. The minimal clinically important difference of the fatigue severity scale calculated using both anchor- and distribution-based methods. ResultsA total of 117 stroke patients were included in the study. Using multidimensional fatigue symptom inventory-short form, global rating of change, and visual analog scale as an anchor, the minimal clinically important difference of fatigue severity scale was obtained at 3.5, 4.5, and 4.5, respectively. The minimal clinically important difference for fatigue severity scale varied from 4.28 to 12.90 using the distribution-based method, with SEM = 4.28 displaying the best sensitivity and specificity for use as minimal clinically important difference. ConclusionsThe minimal clinically important difference value for the fatigue severity scale was estimated at 3.5_12.90 using anchor-based and distribution-based methods. The study's results can be utilized to understand the effectiveness of fatigue interventions in stroke patients in clinical and research settings

Minimal and robust clinically important difference of three fatigue measures in chronic stroke survivors

ABSTRACT Background Fatigue assessment scale (FAS), fatigue subscale of the Profile of Mood States (POMS-F), and vitality subscale of the Short Form Health Survey (SF-36-VT) are among the first and most widely used adapted tools for assessing post-stroke fatigue. Objective To identify the minimal clinically important difference (MCID) and robust clinically important difference (RCID) of FAS, POMS-F, and SF-36-VT in stroke survivors. Methods Participants completed the FAS, POMS-F, and SF-36-VT before and after receiving 6-week intervention including graded activity training and pacing therapy. MCID was calculated using the distribution-based and anchor-based methods. Further, accuracy, sensitivity, and specificity of calculated values using the distribution-based method were used for determining RCID. Result A total of 124 stroke survivors participated in this study. MCID for FAS, POMS-F, and SF-36-VT was found to be 4.86, 3.32, and −10.10 (using score change) and 3.5, 2.5, and −10.5 (using ROC analysis), respectively. Using the distribution-based method, the MCID value obtained for the FAS was in the range of 3.16 to 8.76, for the POMS-F was in the range of 1.49 to 5.63, and for the SF-36-VT was in the range of −15.43 to −5.58. ½SD for FAS, ½ SD and 1.96 SEM for POMS-F, and 1.96 SEM and SD for SF-36-VT showed the best discriminative ability to use as the RCID. Conclusions The MCID and RCID were calculated for FAS, POMS-F, and SF-36-VT using different methods. The results can be used by researchers and clinicians for interpreting their findings in subjects similar to those who participated in this study.

The Impact of a Group-Based Multidisciplinary Rehabilitation Program on the Quality of Life in Patients With Fibromyalgia: Results From the QUALIFIBRO Study.

Patients with fibromyalgia (FM) have a substantially reduced health-related quality of life (HRQoL). Their management should preferably focus on multidisciplinary nonpharmacological interventions. However, the long-term impact of such multicomponent therapies is not fully established. Waiting lists for patients seeking medical treatment are long, making individual-based approaches often unfeasible. The aim of our pragmatic study was to evaluate long-term HRQoL benefits of a comprehensive 8-week group-based multidisciplinary rehabilitation program focusing on patients' coping ability and self-care. A total of 94 patients with clinically confirmed FM agreed to participate in this study. Before entering the program based on group-based cognitive behavioral therapy and graded activity training, patients completed questionnaires to screen for comorbidities. Health-related quality of life was assessed at the start, at 8 weeks, 6 months, and 1 year using the 36-Item Short-Form Health Survey instrument. Changes in HRQoL scores were analyzed according to linear mixed regression modeling. Baseline findings confirmed the substantially low physical and mental HRQoL in FM patients as well as high levels of depression, anxiety, and burnout. Only 2 patients left the program prematurely; 89% participated in the 1-year assessment. By the end of the program, HRQoL was significantly improved in all domains. This effect was maintained at 6 months and 1 year for all subscales. Changes at 1 year were greater in younger patients and those with depressive feelings before the start of treatment. Our group-based program offered to FM patients proved successful with significant improvements in their HRQoL both in the short and long term.

First Dutch guidelines on lipedema using the international classification of functioning, disability and health.

Introduction Lipedema is a chronic, progressive condition that can result in considerable disability. In 2011, the Dutch Society of Dermatology and Venereology organized a task force to create guidelines on lipedema, using the International Classification of Functioning, Disability and Health of the World Health Organization. Guideline development Clinical questions on significant issues in lipedema care were proposed, involving (1) making the diagnosis of lipedema; (2) clinimetric measurements for early detection and adequate follow-up; and (3) treatment. A systematic review of literature published up to June 2013 was conducted. Based on available evidence and experience of the task force, answers were formed and recommendations were stated. The guidelines define criteria to make a medical diagnosis of lipedema, a minimum data set of (repeated) clinical measurements that should be used to ensure early detection and an individually outlined follow-up plan, pillars on which conservative treatment should be based and recommendations on surgical treatment options. Conclusions Little consistent information concerning either diagnostics or therapy can be found in the literature. It is likely that lipedema is frequently misdiagnosed or wrongly diagnosed as only an aesthetic problem and therefore under- or mis-treated. Treatment is divided into conservative and chirurgic treatment. The only available technique to correct the abnormal adipose tissue is surgery. Recommendations To ensure early detection and an individually outlined follow-up, the committee advises the use of a minimum data set of (repeated) measurements of waist circumference, circumference of involved limbs, body mass index and scoring of the level of daily practice and psychosocial distress. Promotion of a healthy lifestyle with individually adjusted weight control measures, graded activity training programs, edema reduction, and other supportive measures are pillars of conservative therapy. Tumescent liposuction is the treatment of choice for patients with a suitable health profile and/or inadequate response to conservative and supportive measures.

Model of understanding fatigue after stroke.

Fatigue is ubiquitous but it is more common and more severe in patients with acute and chronic conditions, including stroke. The reported proportion of people with fatigue after stroke ranges from 23% to 75%.1 The variation in proportion between studies reflects the heterogeneity in the studied populations, time since stroke, and assessment methods for fatigue. Fatigue is common immediately after stroke, and it tends to persist in most but not all patients. It contributes to lower quality of life and a higher risk of death.2,3 How to manage and prevent fatigue is ranked by stroke survivors and health professionals among the top 10 research priorities relating to life after stroke.4 However, there is no effective treatment, which is partly because of our lack of knowledge of its mechanisms. Fatigue after stroke may share some common underlying mechanisms with other conditions. For example, Zedlitz and colleagues found that the psychosocial profiles of stroke patients with fatigue were similar to those reported in patients with cancer, multiple sclerosis, and chronic fatigue syndrome.5 Several fatigue models have been developed for patients with other conditions; a myriad of biological,6,7 psychosocial,8,9 and behavioral factors,9 as well as other symptoms, such as pain and sleep problems,10 are involved. In this review, we explored whether these factors contribute to fatigue after stroke. We systematically reviewed studies of post-stroke fatigue (PSF) and discussed the definition of PSF, its natural history, and its associations. By drawing on literature of fatigue in other conditions alongside evidence from stroke studies, we propose a conceptual model of PSF. This model is potentially useful in understanding the mechanisms of PSF and informing the development of its treatment. In stroke studies, PSF is usually defined by cut-off scores on fatigue …

Cognitive and Graded Activity Training Can Alleviate Persistent Fatigue After Stroke

Fatigue is a common, persistent consequence of stroke, and no evidence-based treatments are currently available to alleviate fatigue. A new treatment combining cognitive therapy (CO) with graded activity training (GRAT), called COGRAT, was developed to alleviate fatigue and fatigue-related symptoms. This study compared the effectiveness of the COGRAT intervention with a CO-only intervention after a 3-month qualification period without intervention. This randomized, controlled, assessor-blind clinical trial was conducted in 8 rehabilitation centers. Eighty-three stroke patients (>4 months after stroke) were randomly assigned to 12 weeks of CO or COGRAT after qualification. Seventy-three patients completed treatment and 68 were available at follow-up. Primary outcomes (Checklist Individual Strength-subscale Fatigue (CIS-f); self-observation list-fatigue (SOL-f)) and secondary outcomes (Hospital Anxiety and Depression Scale, Stroke-Adapted Sickness Impact Profile, SOL-pain, SOL-sleep-D, 6-minute walk test) were collected at baseline (before and after qualification period) and after treatment (immediate and 6-month follow-up). The qualification period showed stable outcome measures. Both treatments showed significant beneficial effects on fatigue (CIS-f: η(p)(2)=0.48, P<0.001) and other outcomes (except pain and anxiety) with intention-to-treat analyses. Gains for the COGRAT group exceeded those in the CO group on number of individuals showing clinical improvement on the CIS-f (≥8 points: 58% versus 24%) and on physical endurance (η(p)(2)=0.20, P<0.001). A 12-week cognitive therapy program can alleviate persistent fatigue after stroke. The best results are obtained when cognitive therapy is augmented with graded activity training.

Post-stroke fatigue: a treatment protocol that is being evaluated

This series of articles for rehabilitation in practice aims to cover a knowledge element of the rehabilitation medicine curriculum. Nevertheless they are intended to be of interest to a multidisciplinary audience. The competency addressed in this article is the neuropsychologist. Purpose: Post-stroke fatigue is a common and debilitating complaint, which has only recently received attention in clinical rehabilitation. Until now, no evidence-based treatments have been available for the condition. Therefore, a new treatment was designed to reduce post-stroke fatigue complaints: Cognitive and Graded Activity Training (COGRAT). Rationale: Following the premise that post-stroke fatigue is primarily caused by brain damage, the treatment aims to prevent fatigue and to manage existing fatigue symptoms. The purpose of the added graded activity programme is to reduce fatigue by changing cognitions and enhancing physical fitness. Theory into practice: COGRAT consists of a cognitive treatment and graded activity programme in small groups over 12 weeks. In the cognitive treatment, patients receive education on post-stroke fatigue and register their activities and fatigue to gain insight into their daily agenda and fatigability. Patients are then taught several compensation strategies. Cognitive behavioural therapy is used to diminish anxiety, facilitate behavioural change and manage fatigue symptoms. The graded activity programme consists of walking on a treadmill, strength training and home work assignments. Maximum heart rate and strength are increased from 40% at the beginning of the training to a maximum of 70%. Considerations for future improvements: COGRAT is currently being evaluated in outpatients with severe post-stroke fatigue in a multicentre randomized controlled trial. Preliminary data suggest both positive short- and long-term effects. Adaptations for other neurological patient groups suffering from fatigue are suggested.

Physiotherapists' treatment approach towards neck pain and the influence of a behavioural graded activity training: An exploratory study

Physiotherapists' treatment approach might influence their behaviour during practice and, consequently, patients' treatment outcome; however, an explicit description of the treatment approach is often missing in trials. The purpose of this prospective exploratory study was to evaluate whether the treatment approach differs between therapists who favour a behavioural graded activity (BGA) program, conservative exercise (CE) or manual therapy, and whether BGA training has influence on the treatment approach. Forty-two therapists participated. BGA therapists received a 2-day training. Treatment approach was measured at baseline and at 3-month follow-up, using the Pain Attitude and Beliefs Scale for Physiotherapists (PABS-PTs). By this method data on the adoption of biomedical or biopsychosocial approaches were generated. Differences were examined with analysis of variance (ANOVA) and independent Student's t-test. Influence of the BGA training was examined with linear regression. At baseline, there were no significant differences between BGA, CE or manual therapists use of biomedical or biopsychosocial approaches, but there was a trend for BGA therapists to score higher on the biopsychosocial approach. At follow-up, their biopsychosocial score remained higher and their biomedical score was lower compared to CE therapists. Corrected regression analysis showed a 4.4 points (95%CI −7.9; −0.8) higher decrease for therapists who followed the BGA training compared to therapists who did not. Our results indicate no significant differences in treatment approach at baseline, and that BGA training might influence therapists' treatment approach since the scores on the biomedical approach decreased.

A cognitive–behavioral return-to-work program: effects on pain patients with a history of long-term versus short-term sick leave

A cognitive–behavioral return-to-work focused program was evaluated in a randomized controlled design, and the effects were compared between two groups of women with musculoskeletal pain. One group of patients ( n=36) had a history of long-term sick leave (>12 months) at the start of the program and the other ( n=36) had a history of short-term sick leave (2–6 months). The outpatient treatment program, conducted by a psychologist, included 12 sessions with the primary aim to help the patients return-to-work. The treatment first included teaching of coping strategies such as applied relaxation, stress management, graded activity training and pacing. Thereafter the patients were taught how to manage difficulties at their return-to-work and how to generalize coping strategies to different risk factors at their work places. The control condition received treatment-as-usual. The results showed that the cognitive–behavioral return-to-work program was more effective than the treatment-as-usual control condition in reducing the number of days on sick leave for patients on short-term sick leave, but not for patients on long-term sick leave. The treatment program also helped the patients on short-term sick leave to increase their ability to control and decrease pain and to increase their general activity level compared to the control condition. These results underscore the need for an early return-to-work focused rehabilitation to prevent long-term sick leave and disability.

Whose Goals Should Guide? A Comparison of Two Forms of Goal Formulation on Operant Activity Training

The purpose of this study was to evaluate the effects of how goals are established in operant, graded activity training. Consequently, five men and one woman with long-term back pain served as their own controls and each subject participated in two exercises: sit-ups and trunk extensions. In the Predetermined Condition, the goals were established, as in many programs, by the physical therapist for the entire treatment period after an examination, interview with the patient, and a baseline period of training. By contrast, in the Negotiated Condition, training goals were based on the individual subject's and the physical therapist's views as well as prior results. All subjects received both types of training programs, but the assignment of exercise type to the condition was randomized to control for possible differences inherent in the exercise itself. Results showed that every subject obtained larger improvements in the Negotiated Condition regardless of type of exercise than in the Predetermined Condition. The difference was particularly clear for four of the six subjects and the overall average improvement was more than twice as great for the Negotiated Condition (median increase = 149%) relative to the Predetermined Condition (median increase = 67%). Part of the difference appeared to be that the Negotiated Condition increased variability in results so that some subjects produced much higher increases. These data suggest that the method employed to determine the training goals in operant activities training is an important variable. This information might be utilized to enhance the effects of the program.

Effects of a cognitive-behavioral pain-management program

A cognitive behavioral multidisciplinary pain management program was evaluated in two separate outcome studies; one controlled study (study I) and one study conducted on a consecutive sample with a long-term follow-up (study II). The 4-week inpatient treatment program included education sessions, goal setting, graded activity training, pacing, applied relaxation, cognitive techniques, social skills training, drug reduction methods, contingency management of pain behaviors, and planning of work return. The outcome of study I showed significant between-group differences in favor of the treatment group on measures of occupational training at 1-month follow-up, activity level in the sparetime at post-treatment and at follow-up, and decreased catastrophizing and pain behaviors at post-treatment. In study II significant improvements over time were found on measures of sick leave, pain intensity, pain interference, life control, affective distress, activity level in the sparetime, physical fitness and use of analgetics at 2-month follow-up and at 1-year follow-up. The results of the two outcome studies reported show that cognitive behavioral multidisciplinary pain management programs can successfully be applied to Swedish musculoskeletal pain patients.
