“…This study involved a secondary analysis of previously published data. 27 Briefly, participants were recruited through the North American Research Committee on Multiple Sclerosis (NARCOMS) patient registry. The recruitment occurred through the random selection of 1000 persons with MS who completed the biannual NARCOMS registry update survey (Fall, 2017) who were mailed letters by NARCOMS staff; this sample size was selected based on an expectation of 25% participation in the current study as estimated by NARCOMS.…”

“…This study involved a secondary analysis of data from a relatively large sample of persons with MS 27 and examined the associations among fatigue, based on the Fatigue Severity Scale (FSS) 28 and device-measured LPA and MVPA as well as sedentary behavior among people with MS; we focused on sedentary behavior, LPA, and MVPA, rather than steps or other variables, based on a representation of the activity continuum. 24 Such an inquiry overcomes the aforementioned problems of previous research in this area, and provides a novel, comprehensive examination of fatigue and physical activity across the activity continuum.…”

Background. Fatigue is a debilitating symptom in multiple sclerosis (MS) that may be associated with reduced physical activity and increased sedentary behavior. Objective. This study examined the associations among fatigue and device-measured physical activity and sedentary behavior in people with MS. Methods. The participants (n = 252) completed the Patient Determined Disease Steps (PDDS) and Fatigue Severity Scale (FSS) and wore a waist-mounted accelerometer for 7 days. Participants were divided into 2 groups based on fatigue severity as measured by the FSS scale. We compared percentage of wear time spent in sedentary, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) between the 2 groups. Results. Persons in the fatigued group (FSS score ≥ 4) spent a greater percentage of time in sedentary behavior ( P = .004) and a lower percentage of time in LPA ( P = .035). Persons in the fatigued group further spent a lower percentage of time in nontransformed MVPA ( P < .001) and square-root-transformed MVPA ( P < .001) than persons in the nonfatigued group. When controlling for PDDS scores and years of education, there were no longer significant differences between groups in sedentary behavior, LPA, or transformed MVPA values; the difference in nontransformed MVPA was still statistically significant but likely the result of nonnormally distributed data. Conclusion. The present study suggests that factors other than fatigue might be associated with physical activity and sedentary behavior in MS, and this group might benefit from focal behavioral interventions that take into account mobility status in persons with MS who have fatigue.

“…The NHANES study measured PA and SB objectively using accelerometery, whereas the present study used self-reported SB time with the IPAQ. In a study that examined both self-reported and accelerometery-based SB time in people with multiple sclerosis, self-reported SB time was 505.6 min/day while the accelerometer detected SB time was 548.5 min/day (19). No studies to date have reported on self-reported or objectively measured SB in people living with dystonia.…”

Physical Activity, Sedentary Behavior, and Barriers to Exercise in People Living With Dystonia

Background: Dystonia is a neurological movement disorder that presents as sustained or intermittent involuntary muscle contractions causing abnormal postures and movements. Knowledge of dystonia is mostly at the impairment level with minimal understanding of activity and participation limitations. Physical activity (PA) is an important aspect of neurological disease management, with wide-ranging benefits for overall health and quality of life. No studies have quantified PA and sedentary behavior (SB), nor explored barriers to being physically active in people with dystonia.Methods: Participants diagnosed with any form of dystonia completed a mixed-methods anonymous online survey on activity behaviors. The International Physical Activity Questionnaire (IPAQ) and Adult Sedentary Behavior Questionnaire (SBQ) assessed self-reported PA and SB. Barriers to exercise engagement were investigated according to the five-factor social-ecological framework and dystonia-specific questions regarding the impact of exercise on symptoms were included.Results: Two-hundred and sixty-three participants consented to the study (mean (SD) age = 55 (13) years, 76% Female). A large proportion of respondents (40%) reported living with cervical dystonia (CD). Overall, the median (IQR) time spent in walking, moderate, and vigorous activity was 60 (0–120), 120 (15–300), and 0 (0–13) min/day, respectively. SB time during weekdays was 285.0 (157.5–465.0) min/day and 345.0 (195.0–502.5) min/day on weekends. Fifty-five percent of participants were dissatisfied with their current level of PA and 75% reported dystonia had decreased their level of PA. Fifty-seven percent found their symptoms were worsened during exercise though the after-effects on symptoms varied. Fatigue, motor symptoms, pain, and poor balance were commonly cited limiting factors. Qualitative and quantitative data indicated difficulties with more vigorous intensity activity. The common barriers to engagement were personal and governmental factors, such as physical impairments, lack of funding and lack of trained exercise professionals.Conclusion: While more than half of respondents indicated they were not satisfied with their current level of PA, and exercise primarily worsened their dystonia symptoms, most participants were meeting the minimum guidelines. Future studies should incorporate robust objective methods of PA and SB measurement and explore the causal mechanisms underpinning exercise-induced aggravation of dystonic symptoms to further enhance life participation of people living with dystonia.

“…However, self-reported measures significantly underestimate sedentary time compared to device measures 15 and typically provide estimates of volume, but not patterns of SB. Similarly, studies examining objective SB have reported age, MS type, disease duration, disability status via the Patient Determined Disease Steps (PDDS) scale 16 and fatigue 17 as correlates, with more recent research showing associations with Social Cognitive Theory constructs 18 . However, these studies used hip-mounted accelerometers, which characterise sedentary behaviour through periods of inactivity measured by count-based movement thresholds (e.g.…”

“…However, these studies used hip-mounted accelerometers, which characterise sedentary behaviour through periods of inactivity measured by count-based movement thresholds (e.g. < 100 counts per min) 16 , 18 . Since movement is determined by acceleration rather than body posture they cannot robustly differentiate between sitting and upright positions and may misclassify static postures such as standing as sedentary behaviour 19 .…”

High levels of sedentary behaviour are associated with poor health outcomes in people with multiple sclerosis (MS). Identifying modifiable correlates of sedentary behaviour for people with MS is essential to design effective intervention strategies to minimise sedentary time. This study aimed to quantify patterns and identify correlates of sedentary behaviour among adults with MS. Fatigue, self-efficacy, walking capability, the physical and psychological impact of MS, health-related quality of life, and participation and autonomy were assessed by questionnaire. Participants wore an activPAL monitor. Total (min/day), prolonged bouts (≥ 30 min) and breaks in sedentary time were calculated. Associations were examined using regression analysis adjusted for demographic and clinical confounders. Fifty-six adults with MS participated (mean ± SD age: 57.0 ± 9.25 years; 66% female). Self-efficacy for control over MS was associated with sedentary time (β = 0.16, 95% CI 0.01, 0.30). Self-efficacy in function maintenance (β = 0.02, 95% CI 0.00, 0.04), health-related quality of life (EuroQol-5D) (β = 31.60, 95% CI 7.25, 55.96), and the autonomy indoors subscale of the Impact on Participation and Autonomy Questionnaire (β = − 5.11, 95% CI − 9.74, − 0.485) were associated with breaks in sedentary time. Future studies should consider self-efficacy, health-related quality of life and participation and autonomy as potential components of interventions to reduce sedentary behaviour.
