“…The SenseWear Arm band (SWA) provided an objective estimate of PA [24] using both mean daily step count and mean daily energy expenditure estimates over a 7-day period. The 5 times sit to stand test (5xSTS) [25], the Modified Canadian Aerobic Fitness Test (mCAFT) [26] and the Godin Health Index of the Godin Leisure-Time Exercise Questionnaire (GLTEQ) [27] measured lower extremity muscle strength, aerobic capacity and PA behaviour, respectively.…”

BackgroundRecent exercise guidelines for people with multiple sclerosis (MS) recommend a minimum of 30 min moderate intensity aerobic exercise and resistance exercise twice per week. This trial compared the secondary outcomes of a combined 10-week guideline based intervention and a Social Cognitive Theory (SCT) education programme with the same exercise intervention involving an attention control education.MethodsPhysically inactive people with MS, scoring 0–3 on Patient Determined Disease Steps Scale, with no MS relapse or change in MS medication, were randomised to 10-week exercise plus SCT education or exercise plus attention control education conditions. Outcomes included fatigue, depression, anxiety, strength, physical activity, SCT constructs and impact of MS and were measured by a blinded assessor pre and post-intervention and 3 and 6 month follow up.ResultsOne hundred and seventy-four expressed interest, 92 were eligible and 65 enrolled. Using linear mixed effects models, the differences between groups on all secondary measures post-intervention and at follow-up were not significant. Post-hoc, exploratory, within group analysis identified improvements in both groups post intervention in fatigue (mean ∆(95% CI) SCT -4.99(−9.87, −0.21), p = 0.04, Control −7.68(−12.13, −3.23), p = 0.00), strength (SCT -1.51(−2.41, −0.60), p < 0.01, Control −1.55(−2.30, −0.79), p < 0.01), physical activity (SCT 9.85(5.45, 14.23), p < 0.01, Control 12.92(4.69, 20.89), goal setting (SCT 7.30(4.19, 10.4), p < 0.01, Control 5.96(2.92, 9.01), p < 0.01) and exercise planning (SCT 5.88(3.37, 8.39), p < 0.01, Control 3.76(1.27, 6.25), p < 0.01) that were maintained above baseline at 3 and 6 month follow up (all p < 0.05). Only the SCT group improved at 3 and 6 month follow up in physical impact of MS(−4.45(−8.68, −0.22), −4.12(−8.25, 0.01), anxiety(−1.76(−3.20, −0.31), −1.99(−3.28, −0.71), depression(−1.51(−2.89, −0.13), −1.02(−2.05, 0.01)) and cognition(5.04(2.51, 7.57), 3.05(0.81, 5.28), with a medium effect for cognition and fitness (Hedges’ g 0.75(0.24, 1.25), 0.51(0.01, 1.00) at 3 month follow up.ConclusionsThere were no statistically significant differences between groups for the secondary outcomes once age, gender, time since diagnosis and type of MS were accounted for. However, within the SCT group only there were improvements in anxiety, depression, cognition and physical impact of MS. Exercising at the minimum guideline amount has a positive effect on fatigue, strength and PA that is sustained at 3 and 6 months following the cessation of the program.Trial registrationClinicalTrials.gov, NCT02301442, retrospectively registered on November 13th 2014.

“…The SWA includes accelerometry and measures of heat flux, galvanic skin response, and skin temperature. While having multiple sensors, there is indication that the SWA produces significant measurement errors for steps in MS, which might be of similar or greater magnitude than spring-levered pedometers and accelerometers, as indicated by the study from Coote et al [77] That study reported that the SWA underestimated manually counted steps by 23.2% for persons with MS who used at most a stick to walk and by 29.4% for those needing bilateral support [77]; this may be caused by the placement on the upper arm rather than near the center of mass. Percentage errors for METs estimation were of smaller magnitude, but still concerning.…”

“…Percentage errors for METs estimation were of smaller magnitude, but still concerning. Compared with measures from a portable metabolic system (i.e., Oxycon Mobile), the SWA overestimated METs by 15.4% for individuals using at most a stick to walk and 6.6% for those needing bilateral support [77]. For reliably estimating physical activity in MS using the SWA, a study by Norris et al [78] provides indication that at least 2 and 4 days of monitoring are required for reliable estimates of steps and energy expenditure in fully ambulatory persons with MS.…”

Introduction: The use of motion sensors for measuring physical activity in multiple sclerosis (MS) has evolved with increasing research particularly during the past decade. Areas covered: This manuscript reviews the literature regarding the application of motion sensors for measuring physical activity in MS. We first describe ‘what is known’ about their use in MS by examining the evidence generated between 1997 and 2012, including the psychometric properties of motion sensors in MS and the development of MS-specific accelerometer cut-points. We then evaluate ‘what is new’ based on research conducted between 2013 and 2017. This includes newer research on psychometric properties of motion sensors in MS, development of new MS-specific accelerometer and step-rate cut-points, sedentary behavior assessment, and research on fitness trackers and multisensors in MS. The final part presents a picture of “what is next” for the applications of motion sensors in MS, especially pertaining new opportunities for testing and using fitness trackers in MS, and tracking disease and disability progression based on motion sensor output. Expert commentary: The use of motion sensors in MS has grown substantially over the years; however, a lot more can be done to explore the full potential and utility of these devices in MS.

“…Further, specific limitations of different devices - questionnaires or activity monitors - have been studied in different populations [18, 42, 62, 63] and rather point to an approximation of “true” PA from different perspectives instead of one golden assessment standard. Thus, individual PA parameters may rather be interpreted as reflecting a subject’s activity level than as meaningful quantitative parameters per se.…”

“…Accuracy of the multi-sensor device SenseWear Pro was acceptable in PwMS [18] against indirect calorimetry as standard, while - to our knowledge - the successor SWAmini with reportedly improved performance [19–21] has not been applied in PwMS. We therefore aim to explore its applicability in this population and convergence of results with those obtained from subjective assessment (IPAQ long version).…”

BackgroundPhysical activity (PA) is frequently restricted in people with multiple sclerosis (PwMS) and aiming to enhance PA is considered beneficial in this population. We here aimed to explore two standard methods (subjective plus objective) to assess PA reduction in PwMS and to describe the relation of PA to health-related quality of life (hrQoL).MethodsPA was objectively measured over a 7-day period in 26 PwMS (EDSS 1.5–6.0) and 30 matched healthy controls (HC) using SenseWear mini® armband (SWAmini) and reported as step count, mean total and activity related energy expenditure (EE) as well as time spent in PA of different intensities. Measures of EE were also derived from self-assessment with IPAQ (International Physical Activity Questionnaire) long version, which additionally yielded information on the context of PA and a classification into subjects’ PA levels. To explore the convergence between both types of assessment, IPAQ categories (low, moderate, high) were related to selected PA parameters from objective assessment using ANOVA. Group differences and associated effect sizes for all PA parameters as well as their relation to clinical and hrQoL measures were determined.ResultsBoth, SWAmini and IPAQ assessment, captured differences in PA between PwMS and HC. IPAQ categories fit well with common cut-offs for step count (p = 0.002) and mean METs (p = 0.004) to determine PA levels with objective devices. Correlations between specifically matched pairs of IPAQ and SWAmini parameters ranged between r .288 and r .507. Concerning hrQoL, the lower limb mobility subscore was related to four PA measures, while a relation with patients’ report of general contentment was only seen for one.ConclusionsBoth methods of assessment seem applicable in PwMS and able to describe reductions in daily PA at group level. Whether they can be used to track individual effects of interventions to enhance PA levels needs further exploration. The relation of PA measures with hrQoL seen with lower limb mobility suggests lower limb function not only as a major target for intervention to increase PA but also as a possible surrogate for PA changes.Electronic supplementary materialThe online version of this article (doi:10.1186/s12883-016-0783-0) contains supplementary material, which is available to authorized users.
