ABSTRACT
OBJECTIVE: The objective of this study was to explore what non-pharmacological interventions have been examined for individuals with antiphospholipid syndrome (APS). METHODS: We conducted a systematic literature search of the databases PubMed, Embase, Scopus, Web of Science, CINAHL, and ClinicalTrials.gov from 1983-Feb. 2023. Our scoping review included studies that examined non-pharmacological interventions for individuals with APS using patient-reported outcome measures. We excluded studies that reported physiological outcomes only. RESULTS: The review yielded one case study on the safety and efficacy of an exercise program for a 15-year-old male with secondary APS using physiological and patient-reported outcome measures. Despite the lack of evidence of non-pharmacological interventions for individuals with APS, one excluded study reported that individuals with APS want guidance about physical activity and exercise. We also found several types of potentially relevant non-pharmacological interventions for individuals with lupus, a disease that often co-occurs with APS. CONCLUSIONS: Non-pharmacological interventions may offer a solution for addressing some non-thrombotic or non-obstetric APS symptoms, such as neurological, physical, and cognitive symptoms that are not well-controlled by anticoagulation. Due to the unique risks associated with APS, research is needed to determine the safety and efficacy of non-pharmacological interventions, particularly those involving exercise. Adopting a comprehensive, multidisciplinary approach to managing patients with APS and involving rehabilitation professionals, who are experts in the design and delivery of non-pharmacological interventions, may provide a foundation for developing and testing novel interventions that improve health outcomes while also fulfilling unmet needs reported by patients.

OBJECTIVES: Symptoms of people who have SSc are heterogeneous and difficult to address clinically. Because diverse symptoms often co-occur and may share common underlying mechanisms, identifying symptoms that cluster together may better target treatment approaches. We sought to identify and characterize patient subgroups based on symptom experience. METHODS: An exploratory hierarchical agglomerative cluster analysis was conducted to identify subgroups from a large SSc cohort from a single US academic medical centre. Patient-reported symptoms of pain interference, fatigue, sleep disturbance, dyspnoea, depression and anxiety were used for clustering. A multivariate analysis of variance (MANOVA) was used to examine the relative contribution of each variable across subgroups. Analyses of variance were performed to determine participant characteristics based on subgroup assignment. Presence of symptom clusters were tallied within subgroup. RESULTS: Participants (n = 587; 84% female, 41% diffuse cutaneous subtype, 59% early disease) divided into three subgroups via cluster analysis based on symptom severity: (i) no/minimal, (ii) mild, and (iii) moderate. Participants in mild and moderate symptoms subgroups had similar disease severity, but different symptom presentation. In the mild symptoms subgroup, pain, fatigue and sleep disturbance was the main symptom cluster. Participants in the moderate symptoms subgroup were characterized by co-occurring pain, fatigue, sleep disturbance, depression and anxiety. CONCLUSION: Identification of distinct symptom clusters, particularly among SSc patients who experience mild and moderate symptoms, suggests potential differences in treatment approach and in mechanisms underlying symptom experience that require further study.

Evidence-based treatments for chronic low back pain (cLBP) typically work well in only a fraction of patients, and at present there is little guidance regarding what treatment should be used in which patients. Our central hypothesis is that an interventional response phenotyping study can identify individuals with different underlying mechanisms for their pain who thus respond differentially to evidence-based treatments for cLBP. Thus, we will conduct a randomized controlled Sequential, Multiple Assessment, Randomized Trial (SMART) design study in cLBP with the following three aims. Aim 1: Perform an interventional response phenotyping study in a cohort of cLBP patients (n = 400), who will receive a sequence of interventions known to be effective in cLBP. For 4 weeks, all cLBP participants will receive a web-based pain self-management program as part of a run-in period, then individuals who report no or minimal improvement will be randomized to: a) mindfulness-based stress reduction, b) physical therapy and exercise, c) acupressure self-management, and d) duloxetine. After 8 weeks, individuals who remain symptomatic will be re-randomized to a different treatment for an additional 8 weeks. Using those data, we will identify the subsets of participants that respond to each treatment. In Aim 2, we will show that currently available, clinically derived measures, can predict differential responsiveness to the treatments. In Aim 3, a subset of participants will receive deeper phenotyping (n = 160), to identify new experimental measures that predict differential responsiveness to the treatments, as well as to infer mechanisms of action. Deep phenotyping will include functional neuroimaging, quantitative sensory testing, measures of inflammation, and measures of autonomic tone.

OBJECTIVES: This study used a qualitative approach to explore how people with SSc experience cognitive changes and how cognitive difficulties impact their functioning. METHODS: Four 90-min focus groups of adults with SSc and self-reported changes in cognition were recruited from a SSc research registry and targeted social media. A focus group guide elicited information from participants via open-ended questions. Content analysis was conducted using grounded theory methodology. RESULTS: There were 20 participants (mean age = 55.5 (11.4) years) comprising 16 (80%) females, 14 (70%) Caucasians, and 11 (55%) people with diffuse cutaneous SSc. Study themes included cognitive difficulties as part of daily life experience, impact of cognitive difficulties on daily life functioning, coping strategies and information seeking. Participants used different terms to describe their experience of cognitive difficulties, and most encountered deficits in short-term memory, language difficulties, decreased executive function, difficulties with concentration and focus, and slow processing speed. Participants expressed frustration with their cognitive difficulties and used coping strategies to lessen their impact. Participants were uncertain about the causes and wanted to understand factors contributing to cognitive difficulties as well as how to manage them. CONCLUSION: Participants with SSc reported cognitive difficulties that had a substantial negative impact on their lives. Improved understanding of cognitive changes could subsequently facilitate development of relevant therapeutic interventions or educational programmes for symptom self-management to reduce impact of cognitive difficulties in people with SSc.

OBJECTIVES: The aim of this study was to comprehensively identify instruments within relevant domains employed to assess lcSSc since the endorsement of its consensus definition in 1988. The overall objective is to inform the creation of a Combined Response Index for Scleroderma Trials Assessing lcSSc (CRISTAL). METHODS: MEDLINE and Embase were searched using terms selected to comprehensively retrieve titles and abstracts mentioning both lcSSc and dcSSc, along with those only mentioning lcSSc, SSc sine scleroderma, limited SSc and/or CREST/CRST. Because our initial assessment of the literature revealed that very few studies included only lcSSc subjects, we also assessed literature that included both cutaneous subsets. A total of 3964 titles and abstracts were screened by two reviewers, and 270 articles were selected for data extraction. RESULTS: We identified 27 domains encompassing 459 instruments. Instruments from 'Skin involvement', 'Pulmonary involvement' and 'Health-related quality of life and general functioning' were the most frequently retrieved. Among the 15 most represented instruments announced as primary end points in efficacy or effectiveness studies, 7 were clinician-reported outcomes (ROs), 7 were patient ROs, and one was a performance outcome (6 min-walk test). The mean proportion of lcSSc patients in studies of lcSSc, including studies that mention both lcSSc and dcSSc, was 56.4%, demonstrating that this subset is underrepresented in the literature, given that the prevalence of lcSSc ranges from 60% to 80% in national registries and international cohorts. CONCLUSION: This scoping literature review provides a comprehensive identification of domains and outcomes used to assess lcSSc. Our results also highlight that lcSSc is underrepresented in the literature.

OBJECTIVE: African American older adults living in disadvantaged communities are disproportionately burdened by disabling pain. To address their needs, we tested the feasibility and potential effects of a cognitive-behavioral chronic pain self-management program delivered by community health workers. DESIGN: A single-group, pre-post evaluation of the STEPS-2 (Seniors using Technology to Engage in Pain Self-management) intervention, in which participants learned pain-management skills through web-based videos. They were also given wearable activity trackers to facilitate incremental increases in walking. In weekly telephone calls, community health workers helped participants apply skills and set goals. SUBJECTS/SETTING: Thirty-one adults in Detroit, Michigan (97% African American, 97% female, mean 68.7 years), with chronic musculoskeletal pain. METHODS: Participants completed telephone surveys at baseline and eight weeks. We measured changes in PROMIS pain interference and pain intensity, as well as Patient Global Impression of Change in pain and functioning. Feasibility indicators included participant engagement and satisfaction, and fidelity to session protocols by community health workers. RESULTS: Participants on average completed 6.6/7 sessions, and 100% agreed or strongly agreed that they improved their understanding of pain management. Average community health worker fidelity score was 1.79 (0 to 2 scale). Pain interference decreased from baseline to post-program (T-score 61.6 to 57.3, P=.000), as did pain intensity (0 to 10 scale, 6.3 to 5.1, P=.004). Approximately 90% of participants reported that pain and function were at least "a little better" since baseline. CONCLUSIONS: An intervention combining mobile health tools with support from community health workers holds promise for improving pain outcomes among underserved older adults.

Frailty is a powerful prognostic tool in cirrhosis. Claims-based frailty scores estimate the presence of frailty without the need for in-person evaluation. These algorithms have not been validated in cirrhosis. Whether they measure true frailty or perform as well as frailty in outcome prediction is unknown. We evaluated 2 claims-based frailty scores-Hospital Frailty Risk Score (HFRS) and Claims-Based Frailty Index (CFI)-in 3 prospective cohorts comprising 1100 patients with cirrhosis. We assessed differences in neuromuscular/neurocognitive capabilities in those classified as frail or nonfrail based on each score. We assessed the ability of the indexes to discriminate frailty based on the Fried Frailty Index (FFI), chair stands, activities of daily living (ADL), and falls. Finally, we compared the performance of claims-based frailty measures and physical frailty measures to predict transplant-free survival using competing risk regression and patient-reported outcomes. The CFI identified neuromuscular deficits (balance, chair stands, hip strength), whereas the HFRS only identified poor chair-stand performance. The CFI had areas under the receiver operating characteristic curve (AUROCs) for identifying frailty as measured by the FFI, ADL, and falls of 0.57, 0.60, and 0.68, respectively; similarly, the AUROCs were 0.66, 0.63, and 0.67, respectively, for the HFRS. Claims-based frailty scores were associated with poor quality of life and sleep but were outperformed by the FFI and chair stands. The HFRS, per 10-point increase (but not the CFI) predicted survival of patients in the liver transplantation (subdistribution hazard ratio [SHR], 1.08; 95% confidence interval [CI], 1.03-1.12) and non-liver transplantation cohorts (SHR, 1.13; 95% CI, 1.05-1.22). Claims-based frailty scores do not adequately associate with physical frailty but are associated with important cirrhosis-related outcomes.

OBJECTIVE: SSc reduces upper extremity function and performance of everyday activities; however, there are few evidence-based rehabilitation interventions. This study examined short and longer-term effects of two occupational therapy interventions on hand disability. METHODS: Participants with diffuse cutaneous SSc were randomized to one of two 18-week interventions: Intensive group, receiving eight weekly in-person occupational therapy sessions with App-delivered home exercises, or App Alone group. The primary outcome was QuickDASH hand disability; secondary outcomes were physical function (PROMIS scale), and total active hand motion. Linear mixed models were used to examine treatment effects. RESULTS: Most participants were female (72%); the mean age was 52 years (13.4) (n = 32). There were no significant between-group effects on QuickDASH (P = 1.0; mean change -6.4 on 0-100 scale in both groups at 18 weeks). Left lateral pinch, an exploratory outcome, improved in App Alone compared with Intensive from baseline to 18 weeks. Within groups, the Intensive group had the largest improvements after 8 weeks (-8.5 on QuickDASH; P = 0.03), but then lost gains from 8 to 18 weeks while the App Alone group had modest improvements from baseline to 8 weeks, but then continued to improve. Of completers, 50% had clinically meaningful improvement on QuickDASH in the Intensive group and 64% had improvement in App Alone. CONCLUSION: Both interventions showed beneficial effects on hand disability. Participants in the App Alone group improved equally to the Intensive group at 18 weeks. Our findings provide support for further study into telehealth rehabilitation approaches. TRIAL REGISTRATION: NCT03482219.

OBJECTIVES: This study developed a musculoskeletal ultrasound (MSUS) protocol to evaluate rehabilitation outcomes in systemic sclerosis. MATERIALS & METHODS: Three MSUS methods (grey scale, Doppler, strain elastography) and two acquisition techniques (long versus short axis; transducer on skin versus floating on gel) were examined in the forearm before and after rehabilitation treatment. For grey-scale, tissue thickness measures, intra- and inter-rater reliability were calculated (ICCs), and paired t-tests examined differences among techniques. RESULTS: Five people with diffuse cutaneous systemic sclerosis participated. The most valid and reliable grey-scale technique was with the transducer in long-axis, floating on gel. Doppler and strain elastography did not detect changes. Both dermal and subcutaneous thickness measurement error was small; intra- and inter-rater reliability was good to excellent. Preliminary data indicate that treatment may lead to dermal thinning. CONCLUSION: A replicable protocol was established and may be an adjunct to rehabilitation outcome measurement in systemic sclerosis.
ABSTRACT
BACKGROUND: Frailty is common in cirrhosis and associated with mortality, hospitalization, and reduced quality of life. Interventions aimed at forestalling frailty are limited by a lack of understanding of underlying physiologic deficits. AIMS: This study's aim was to examine contributions of discrete sensorimotor and neurocognitive capacities to conventional frailty measures of unipedal stance time, chair stands, and grip strength. METHODS: This cross-sectional study enrolled 119 outpatients with cirrhosis (50% female, aged 62.9 ± 7.3 years). Capacities included sensory (lower limb sensation and visual contrast), neurocognitive (Number Connection Tests A and B, simple and recognition reaction time), and muscular (hip/core strength determined by lateral plank time (LPT)). Bivariate analyses and linear regression models were performed to identify significant contributors to each frailty measure. RESULTS: The average performance was 9.8 ± 3.9 chair stands, 12.7 s ±9.9 unipedal stance time, and 60.3 ± 25.6 lb grip strength. In multivariate models, factors explained 40% of variance in unipedal stance and 43% of variance in chair stands. The LPT was most strongly associated with unipedal stance and chair stands. Grip strength was associated with LPT, but did not have physiologic predictors. CONCLUSIONS: Clinically useful measures of frailty in adults with cirrhosis can be explained by disease severity but also deficits in strength and neurocognitive function. Recognition reaction time, a novel measure in cirrhosis, had a significant contribution to frailty. These findings have implications for frailty assessment and suggest that the optimal rehabilitation approach to frailty targets neurocognitive function in addition to strengthening.

BACKGROUND: Wearable activity trackers may facilitate walking for chronic pain management. OBJECTIVE: We assessed the acceptability of a commercially available tracker and three alternative modes of reporting daily steps among older adults in a low-income, urban community. We examined whether using the tracker (Fitbit ZipTM) was associated with improvements in functioning and activity. DESIGN: Randomized controlled pilot and feasibility trial. SUBJECTS: Fifty-one African American adults in Detroit, Michigan, aged 60 to 85 years, with chronic musculoskeletal pain (28 in the intervention group, 23 controls). METHODS: Participants completed telephone surveys at baseline and eight weeks. Intervention participants wore trackers for six weeks, alternately reporting daily step counts via text messages, automated telephone calls, and syncing (two weeks each). We used multimethods to assess satisfaction with trackers and reporting modalities. Adherence was indicated by the proportion of expected days on which valid step counts were reported. We assessed changes in pain interference, physical function, social participation, walking frequency, and walking duration. RESULTS: More than 90% of participants rated trackers as easy to use, but some had technical or dexterity-related difficulties. Text reporting yielded 79% reporting adherence vs 69% each for automated calls and syncing. Intervention participants did not show greater improvement in functioning or walking than controls. CONCLUSIONS: With appropriate support, wearable activity trackers and mHealth reporting for chronic pain self-care are feasible for use by vulnerable older adults. Future research should test whether the effects of trackers on pain-related outcomes can be enhanced by incorporating behavior change strategies and training in evidence-based cognitive-behavioral techniques.

Background: Symptom severity is negatively associated with physical activity in multiple sclerosis (MS). However, it is unclear how physical activity and symptoms correlate on a day-to-day basis in persons with MS. Purpose: To determine the temporal within-person associations of pain, fatigue, depressed mood, and perceived cognitive function with physical activity in MS. Methods: Ambulatory adults with MS (N = 107) completed 7 days of home monitoring. Continuous physical activity data (assessed via wrist-worn accelerometer) and concurrent ecological momentary assessment (5X/day) of pain, fatigue, depressed mood, and perceived cognitive function were collected. Data were analyzed using multilevel mixed modeling. Results: Fatigue and depressed mood demonstrated bidirectional associations with physical activity, whereas pain and cognitive function did not. Higher than usual fatigue (B = -5.83, p = .001) and depressed mood (B = -4.12, p = .03) were followed by decreased physical activity. In contrast, higher than usual physical activity was associated with subsequent decline in fatigue (B = -0.001, p = .02) and depressed mood (B = -0.0007, p = .02); however, the association between physical activity and fatigue varied across the day. Conclusions: Physical activity is dynamically related to fatigue and mood on a moment-to-moment basis in MS. Efforts to increase physical activity in MS must incorporate a focus on how symptoms affect and are affected by activity.

Falls are prevalent for people with cirrhosis and commonly lead to loss of independence, reduced quality of life, and mortality. Despite a critical need for fall prevention in this population, cirrhosis-specific fall-related mechanisms are not well understood. We posit that most falls in this patient population are due to a coalescence of discrete subclinical impairments that are not typically detected at the point of care. The combined effect of these subtle age- and disease-related neurocognitive and muscular impairments leads to the inability to respond successfully to a postural perturbation within the available 300 to 400 ms. This article provides a conceptual model of physiological resilience to avoid a fall that focuses on attributes that underlie the ability to withstand a postural perturbation and their clinical evaluation. Evidence supporting this model in cirrhosis and other high fall risk conditions will be synthesized and suggestions for fall assessment and treatment will be discussed.

PURPOSE: Perceived fatigability, reflective of changes in fatigue intensity in the context of activity, has emerged as a potentially important clinical outcome and quality of life indicator. Unfortunately, the nature of perceived fatigability is not well characterized. The aim of this study is to define the characteristics of fatigability through the development of a conceptual model informed by input from key stakeholders who experience fatigability, including the general population, individuals with multiple sclerosis (MS), and individuals with fibromyalgia (FM). METHODS: Thirteen focus groups were conducted with 101 participants; five groups with n = 44 individuals representing the general population, four groups with n = 26 individuals with MS, and four groups with n = 31 individuals with FM. Focus group data were qualitatively analyzed to identify major themes in the participants' characterizations of perceived fatigability. RESULTS: Seven major themes were identified: general fatigability, physical fatigability, mental fatigability, emotional fatigability, moderators of fatigability, proactive and reactive behaviors, and temporal aspects of fatigability. Relative to those in the general sample, FM or MS groups more often described experiencing fatigue as a result of cognitive activity, use of proactive behaviors to manage fatigability, and sensory stimulation as exacerbating fatigability. CONCLUSIONS: Fatigability is the complex and dynamic process of the development of physical, mental, and/or emotional fatigue. Trait- and state-like biological, psychological, social, and environmental moderators contribute to tremendous variability in fatigability (both between and within-person variability). Future research to further characterize fatigability across populations, test treatments for fatigability, and develop new measures of this construct are greatly needed.

OBJECTIVE: Our objective was to evaluate interunit agreement and construct validity of two activity monitors (Actiwatch Score and PRO-Diary) in people with and without spinal cord injury. METHOD: Thirty-eight participants (19 with spinal cord injury; 19 age- and sex-matched controls; mean age = 49 yr) wore both monitors and completed tasks during one visit ranging in physical intensity. To compare activity by group and monitor, we conducted t tests. We assessed interunit agreement using intraclass correlations and Bland-Altman plots. RESULTS: Both monitors demonstrated significantly different increasing physical activity levels with higher intensity tasks. Participants with spinal cord injury had similar activity counts within tasks compared with controls except for walking-wheeling. Agreement was high between monitors across tasks (interclass correlation coefficients = .78-.97). CONCLUSION: Both monitors demonstrated good construct validity for measuring physical activity across activities and high agreement. Either monitor is appropriate to examine physical activity patterns in people with spinal cord injury.

OBJECTIVE: This study assessed the feasibility and preliminary efficacy of an online-assisted, occupational therapist-delivered, cognitive-behavioral therapy intervention to promote physical function in patients with knee osteoarthritis (KOA). METHOD: Fifty-seven participants with KOA were randomized 2:1 to the Engage program (eight clinic-based sessions supported by online modules) or usual care. Using analysis of covariance, we estimated Engage's effect on physical function (Western Ontario and McMaster Universities Osteoarthritis Index's Physical Function subscale [WOMAC-PF]) at 6 mo. RESULTS: Data were analyzed on 46 completers. Engage was associated with a small effect (η² = 0.01) on the WOMAC-PF. More Engage participants than controls reported much or very much improvement (45% vs. 13%; p = .03). Satisfaction was high, and 30 of 31 participants attended six sessions or more. CONCLUSION: An online-supported cognitive-behavioral program for people with KOA delivered by occupational therapists is feasible and may contribute to improved physical function.
ABSTRACT
OBJECTIVE: To examine the temporal associations, within day and day to day, between pain, fatigue, depressed mood, and cognitive function in multiple sclerosis (MS). DESIGN: Repeated-measures study involving 7 days of ecological momentary assessment (EMA) of symptoms 5 times a day; multilevel mixed models were used to analyze data. SETTING: Community. PARTICIPANTS: Ambulatory adults (N=107) with MS. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: EMA of pain, fatigue, depressed mood, and cognitive function rated on a 0 to 10 scale. RESULTS: Fatigue and pain were linked within day such that higher pain was associated with higher subsequent fatigue (B=.09, P=.04); likewise, higher fatigue was associated with higher pain in the following time frame (B=.05, P=.04). Poorer perceived cognitive function preceded increased subsequent pain (B=.08, P=.007) and fatigue (B=.10, P=.01) within day. Depressed mood was not temporally linked with other symptoms. In terms of day-to-day effects, a day of higher fatigue related to decreased next day fatigue (B=-.16, P=.01), and a day of higher depressed mood related to increased depressed mood the next day (B=.17, P=.01). There were no cross-symptom associations from one day to the next. CONCLUSIONS: Findings provide new insights on how common symptoms in MS relate to each other and vary within and over days. Pain and fatigue show evidence of a dynamic bidirectional relation over the course of a day, and worsening of perceived cognitive function preceded worsening of both pain and fatigue. Most temporal associations between symptoms occur within the course of a day, with relatively little carryover from one day to the next.

OBJECTIVE: To describe the daily variability and patterns of pain, fatigue, depressed mood, and cognitive function in persons with multiple sclerosis (MS). DESIGN: Repeated-measures observational study of 7 consecutive days of home monitoring, including ecological momentary assessment (EMA) of symptoms. Multilevel mixed models were used to analyze data. SETTING: General community. PARTICIPANTS: Ambulatory adults (N=107) with MS recruited through the University of Michigan and surrounding community. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: EMA measures of pain, fatigue, depressed mood, and cognitive function rated on a 0 to 10 scale, collected 5 times a day for 7 days. RESULTS: Cognitive function and depressed mood exhibited more stable within-person patterns than pain and fatigue, which varied considerably within person. All symptoms increased in intensity across the day (all P<.02), with fatigue showing the most substantial increase. Notably, this diurnal increase varied by sex and age; women showed a continuous increase from wake to bedtime, whereas fatigue plateaued after 7 pm for men (wake-bed B=1.04, P=.004). For the oldest subgroup, diurnal increases were concentrated to the middle of the day compared with younger subgroups, which showed an earlier onset of fatigue increase and sustained increases until bed time (wake-3 pm B=.04, P=.01; wake-7 pm B=.03, P=.02). Diurnal patterns of cognitive function varied by education; those with advanced college degrees showed a more stable pattern across the day, with significant differences compared with those with bachelor-level degrees in the evening (wake-7 pm B=-.47, P=.02; wake-bed B=-.45, P=.04). CONCLUSIONS: Findings suggest that chronic symptoms in MS are not static, even over a short time frame; rather, symptoms-fatigue and pain in particular-vary dynamically across and within days. Incorporation of EMA methods should be considered in the assessment of these chronic MS symptoms to enhance assessment and treatment strategies.

OBJECTIVE: To examine the relative association between daily change in pain, fatigue, depressed mood, and cognitive function and 4 outcomes-positive affect and well-being, ability to participate in social roles and activities, upper extremity (UE) functioning, and lower extremity (LE) functioning. DESIGN: Data analysis, multilevel mixed modeling. SETTING: General community. PARTICIPANTS: Ambulatory adults (N=102) with multiple sclerosis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Customized short-forms of the Quality of Life in Neurological Disorders positive affect and well-being, UE functioning, and LE functioning item banks and the Patient-Reported Outcomes Measurement Information System ability to participate in social roles and activities item bank adapted for daily use and administered as end-of-day diaries. RESULTS: Above and beyond the effects of demographic and clinical covariates, daily pain was associated with 3 of the 4 outcomes; days of higher than usual pain were related to lower same-day social participation (unstandardized ß, B=-1.00; P=.002), UE functioning (B=-1.04; P=.01), and LE functioning (B=-.71; P=.04). Daily fatigue and depressed mood were independently related to daily positive affect and well-being; days of worse fatigue (B=-.54; P=.006) and depressed mood (B=-1.17; P<.0001) were related to lower same-day well-being. CONCLUSIONS: The results indicate the role of fluctuations in symptoms in daily functioning and quality of life of individuals with multiple sclerosis. Daily increases in pain intensity are related to social and physical functioning, whereas increases in fatigue and depressed mood are related to lower daily well-being. Findings implicate a person-centered approach to monitoring and treating symptoms.

OBJECTIVE: To examine how self-reported pain- and fatigue-related activity interference relates to symptoms and physical activity (PA) in daily life among people with knee or hip osteoarthritis. DESIGN: Cross-sectional study with a 7-day repeated-measures assessment period. SETTING: General community. PARTICIPANTS: Participants (N=154; mean age, 65y; 60% women [n=92]) with knee or hip osteoarthritis and pain lasting ≥3 months. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pain- or fatigue-related activity interference items on the Brief Pain Inventory or Brief Fatigue Inventory, respectively, from baseline survey, momentary pain and fatigue severity (measured 5times/d for 7d), and PA measured with a wrist-worn accelerometer over 7 days. We hypothesized that perception of pain- and fatigue-related activity interference would moderate the association between symptoms (pain or fatigue) and PA. People with higher pain- or fatigue-related activity interference were thought to have stronger negative associations between momentary ratings of pain and fatigue and PA than did those with lower activity interference. RESULTS: Pain-related activity interference moderated the association between momentary pain and PA, but only in the first part of the day. Contrary to expectation, during early to midday (from wake-up time through 3 pm), low pain-related interference was associated with stronger positive associations between pain and PA but high pain-related interference was associated with a small negative association between pain and PA. Fatigue-related activity interference did not moderate the relation between fatigue and activity over the course of a day. CONCLUSIONS: Depending on a person's reported level of pain-related activity interference, associations between pain and PA were different earlier in the day. Only those with high pain-related activity interference had lower levels of PA as pain increased and only in the morning. High pain-related activity interference may be important to address, particularly to maintain PA early in the day despite pain.
