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

The minimal clinically important difference of two multifaceted fatigue evaluation questionnaires in chronic stroke

PURPOSE

This research sought to ascertain the Minimal Clinically Important Difference (MCID) and Robust Clinically Important Difference (RCID) of the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and Chalder Fatigue Questionnaire-11 (CFQ-11) as two important concepts for the clinical interpretation of the results in chronic post-stroke population.

METHODS

A total of 128 subjects with chronic post-stroke completed the MFSI-SF and CFQ-11 before and after six weeks of intervention. The MCIDs were derived using both anchor- and distribution-based methods; however, only anchor-based methods were used to estimate RCIDs.

RESULTS

Anchor-based MCIDs for MFSI-SF and CFQ-11 were in the range of -5 to -6.28 and -2 to -4.56, respectively. Distribution-based MCIDs in MFSI-SF and CFQ-11 were calculated in the range of -4.17 to -24.05 and -1.72 to -7.68, respectively. RCID ranges of -10 to -15 were obtained for the MFSI-SF and -6 to -7.33 for the CFQ-11.

CONCLUSION

These findings may have implications for clinical experts in the clinical interpretation of fatigue changes observed in MFSI-SF and CFQ-11 in individuals with chronic stroke.

Minimal and robust clinically important differences for patient-reported outcome measures of fatigue in chronic stroke survivors after fatigue rehabilitation

PURPOSE

The minimal and robust clinically important difference (MCID and/or RCID) are essential in assessing the clinical significance of multidimensional fatigue inventory-20 and checklist of individual strength-fatigue subscale questionnaires changes scores. This is the first study to determine the MCID and RCID of these questionnaires in chronic stroke survivors.

MATERIALS AND METHODS

A total of 125 participants in an observational cohort study completed MFI-20 and CIS-fs before and after receiving multidisciplinary rehabilitation (cognitive behavioral therapy, graded exercise and adaptive pacing therapy). Anchor-based MCIDs and RCIDs were calculated using the mean change, the mean difference and the receiver operating characteristics methods. To evaluate the accordance between of distribution-based MCIDs (1 SD, ½ SD, SEM, 1.96 SEM and MDC values) with anchored values, the accuracy, sensitivity, specificity and Youden's index were calculated.

RESULTS

The anchored MCIDs were between -5 to -7.33 for MFI-20 and -4.87 to -5.40 for CIS-fs. The anchored RCIDs ranged from -5 to -13.88 and -6 to -9.88 for MFI-20 and CIS-fs, respectively. The values of ½ SD and SEM for CIS-fs were consistent with anchored RCIDs.

CONCLUSIONS

The estimated MCIDs and RCIDs of MFI-20 and CIS-fs can help researchers and clinicians interpret their chronic stroke patient data.

Changes in mood states during inpatient rehabilitation after spinal cord injury

DESIGN

Retrospective observational study.

OBJECTIVE

To analyze changes in mood states during the acute phase of inpatient rehabilitation for spinal cord injury (SCI) and the factors associated with worse mood states and less improvement.

SETTING

Spinal unit in Italy.

PARTICIPANTS

The study included people with SCI admitted between 2014 and 2019 and treated for psychological problems with a focus on 'emotion processing' and 'emotional adjustment'. The sample included 170 patients (71.8% male, mean age 47.1 ± 16, range 17-78), 46.5% with tetraplegia and 50% with comorbidities.

OUTCOME MEASURES

The Profile of Mood States (POMS) questionnaire was used to assess mood states at baseline and at the end of treatment. Multiple linear regression models were used to identify factors associated with changes in mood states during treatment.

RESULTS

At baseline, patients with distress related to SCI diagnosis reported lower levels of vigor, whereas those with distressing life events reported higher levels of anger and confusion-bewilderment. POMS subscales improved significantly by at least 4 points. ASIA Impairment Scale (AIS) C score, living with family of origin, comorbidities and critical events during hospitalization were associated with greater improvements, whereas higher education was associated with less improvement in depressive mood. In tetraplegic patients, higher improvements in depressive mood were associated with greater independence at discharge, whereas in patients with paraplegia, higher improvements in anxiety and vitality were associated with better mobility.

CONCLUSION

Our results indicate that mood states improved in people with SCI receiving a psychological treatment. Socio-demographic and SCI-related characteristics associated with a greater effect of psychological treatment should be considered in order to tailor the intervention.

Feasibility of an Application-Based Outpatient Rehabilitation Program for Stroke Survivors: Acceptability and Preliminary Results for Patient-Reported Outcomes

BACKGROUND

The majority of stroke survivors experience long-term impairments. Regular physical activity and other lifestyle modifications play an important role in rehabilitation. Outpatient rehabilitation using telemedicine might be suitable to improve functional ability and long-term secondary prevention. The Strokecoach Intervention Program (SIP, Strokecoach GmbH, Cologne, Germany) comprises training, coaching and monitoring with the aim of improving or at least maintaining functional independence and preventing further stroke through more targeted physical activity. The SIP is provided as blended care, which refers to the integrated and coordinated delivery of healthcare services that combines traditional in-person interactions with technology-mediated interventions, optimizing the use of both face-to-face and virtual modalities to enhance patient outcomes.

OBJECTIVE

The aim of this study was to evaluate the acceptance of the SIP by the participants and its practical application, as well as to obtain initial indications of effects of the SIP on the basis of patient-related outcome measures, blood pressure measurements and recording of physical activity in parallel with the intervention.

METHODS

Data from individuals with stroke participating in the SIP were analyzed retrospectively. Within the SIP, participants received an application-based training program, were instructed to measure their blood pressure daily and to wear an activity tracker (pedometer). During the intervention period of either 6 or 12 weeks, the participants were supported and motivated by a personal coach via a messenger application. The primary outcomes of the analysis were recruitment, acceptance of and satisfaction with the SIP. Secondary outcomes included functional measures, mobility and health-related quality of life.

RESULTS

A total of 122 individuals with stroke could be recruited for the SIP. A total of 96 out of 122 were able to start the program (54% female, mean age 54.8 (SD = 13.1), 6.1 (SD = 6.6) years after stroke onset) and 88 completed the SIP. Participants wore the activity tracker on 66% and tracked their blood pressure on 72% of their intervention days. A further analyzed subgroup of 38 participants showed small improvements in patient-reported outcomes such as health-related quality of life (SF-36) with an increase of 12 points in the subdomain mental health, vitality (12.6) and physical functioning (9.1). However, no statistically significant improvements were found in other performance-based measures (Timed Up and Go test, gait speed).

CONCLUSIONS

This study showed that a blended therapy approach for stroke survivors with mild to moderate impairments in the chronic phase is feasible and was highly accepted by participants, who benefitted from the additional coaching.

Measurement properties of instruments to measure the fatigue domain of vitality capacity in community-dwelling older people: an umbrella review of systematic reviews and meta-analysis

BACKGROUND

Vitality capacity (VC) is a key domain of intrinsic capacity (IC) and is the underlying biophysiological aspect of IC. Energy and metabolism (E&M) is one of the domains of VC. Fatigue is one of the main characteristics of E&M.

OBJECTIVE

The aims of this umbrella review are (i) to identify the available instruments suitable for measuring fatigue in community-dwelling older adults and (ii) to critically review the measurement properties of the identified instruments.

DESIGN

Umbrella review.

SETTING

Healthcare.

SUBJECTS

Community-dwelling older adults.

METHODS

PubMed and Web of Knowledge were systematically screened for systematic reviews and meta-analysis reporting on fatigue instruments resulting in 2,263 articles (last search 5 December 2022). The COSMIN checklist was used to appraise psychometric properties and the AMSTAR for assessing methodological quality. Data on fatigue instruments, construct, reference period, assessment method, validated population, reliability, validity, responsiveness and predictive validity on negative health outcomes were extracted.

RESULTS

10 systematic reviews and 1 meta-analysis were included in this study. 70 fatigue instruments were identified in the literature and 21 were originally designed for fatigue. The Fatigue Severity Scale (FSS), Pittsburgh Fatigability Scale (PFS) and Visual Analogue scale (VAS-F), Fatigue Impact Scale (FIS) and the Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) presented good psychometric properties.

CONCLUSIONS

The FSS, FIS, FACIT-F, PFS and the VAS-F presented good psychometric properties in various conditions. Therefore, these instruments could be used to quantify trajectories in the domain E&M in the context of VC in community-dwelling older adults.

The Effects of Vestibular Rehabilitation on Poststroke Fatigue: A Randomized Controlled Trial Study

Background

A major complication caused by stroke is poststroke fatigue (PSF), and by causing limitations in doing activities of daily living (ADL), it can lower the quality of life.

Objective

The present study is an attempt to examine the effects of vestibular rehabilitation on BADL (Basic Activities of Daily Living), fatigue, depression, and Lawton Instrumental Activities of Daily Living (IADL) in patients with stroke.

Method

Patients with a history of stroke took part voluntarily in a single-blind clinical trial. The participants were allocated to control and experimental groups randomly. The experimental group attended 24 sessions of vestibular rehabilitation protocol, while the control group received the standard rehabilitation (including three sessions per week each for around 60 min). To measure fatigue, the Fatigue Impact Scale (FIS) and the Fatigue Assessment Scale (FAS) were used. Depression, BADL, and IADL were measured using the Beck Depression Inventory-II (BDI-II), Barthel Index (BI), and Lawton Instrumental Activities of Daily Living, respectively. All changes were measured from the baseline after the intervention.

Results

Significant improvement was found in the experimental group compared to the control group (p < 0.05) in FIS (physical, cognition, and social subscales), FAS, BDI-II, BADL, and IADL. Moreover, the results showed small to medium and large effect sizes for the physical subscale of FIS and FAS scores based on Cohen's d, respectively; however, no significant difference was found in terms of cognition and social subscales of FIS, BDI-II, BADL, and IADL scores.

Conclusion

It is possible to improve fatigue, depression, and independence in BADL and IADL using vestibular rehabilitation. Thus, it is an effective intervention in case of stroke, which is also well tolerated.
