We examined the reliability of scores from physical activity monitors in a sample of 193 individuals with multiple sclerosis (MS) who wore a pedometer and an accelerometer for a 7-day period. There were no significant differences among days for the pedometer (p = .12) or the accelerometer (p = .15) indicating that week and weekend days can be analyzed in a single intra-class correlation (ICC) analytic model. The 7 days of monitoring yielded ICC estimates of .93 for both the pedometer and…

Use of Accelerometers to Measure Real-Life Physical Activity in Ambulatory Individuals with Multiple Sclerosis: A Pilot Study.
TLDR
This cohort demonstrated that the amount of PA is inversely proportional to the degree of physical disability, and accelerometers can be used to objectively quantify PA levels in individuals with MS with different disability levels.
Reliability of Physical-Activity Measures Over Six Months in Adults with Multiple Sclerosis: Implications for Designing Behavioral Interventions
TLDR
Overall, the measures had acceptable, but different, reliability over six months in this sample of mostly women with relapsing–remitting MS, and power analyses using the reliability estimates indicated vastly different sample sizes for the measures of physical activity and when compared with the default parameter in software packages.
The effect of walking mobility on the measurement of physical activity using accelerometry in multiple sclerosis
TLDR
The data suggest that accelerometers are measuring both physical activity and walking mobility in individuals with multiple sclerosis, whereas self-report measures are measuring physical activity in Individuals withmultiple sclerosis, including those with ambulatory impairment.
Accelerometry in persons with multiple sclerosis: Measurement of physical activity or walking mobility?
Objective monitoring of physical activity behavior in multiple sclerosis
TLDR
Researchers and clinicians now have a better set of motion sensors that provide objective, valid, and reliable measures of physical activity in persons with MS, which should support an expanding interest and study of physicalActivity and its determinants and consequences in MS as well as monitoring physical activity and its change in clinical practice.
Physical Activity Correlates With Neurological Impairment and Disability in Multiple Sclerosis
TLDR
Findings provide a preliminary basis for using an accelerometer and the SI and PS as outcome measures in large-scale prospective and experimental examinations of the effect of physical activity behavior on disability and dependence in MS.
Measuring free-living physical activity in adults with and without neurologic dysfunction with a triaxial accelerometer.
Levels and Rates of Physical Activity in Older Adults with Multiple Sclerosis
TLDR
Results indicated that older adults with MS engaged in less MVPA and more sedentary behavior than middle-aged and young adult with MS, highlighting the importance of developing physical activity interventions as an effective means for managing the progression and consequences of MS in older adults.
Accelerometry is associated with walking mobility, not physical activity, in persons with multiple sclerosis.
Validity of the Marshall Sitting Questionnaire in people with multiple sclerosis
TLDR
Preliminary evidence for the validity of the Marshall Sitting Questionnaire in people with multiple sclerosis is indicated, and the application of an alternative prediction model to improve the accuracy of the MSQ estimates is supported.

Quantified measurement of activity provides insight into motor function and recovery in neurological disease
TLDR
Ambulatory monitoring as an outcome measure has potential for improving the evaluation of ambulation and providing insight into participation as well as evaluating the impact of impairments in neurological disorders.

Sources of variance in daily physical activity levels in the seasonal variation of blood cholesterol study.
TLDR
This study is among the first to have examined the sources of variance in daily physical activity levels in a large population of adults using 24-hour physical activity recall, providing insight for understanding the strengths and limitations of short term and long term physical activity assessments employed in epidemiologic studies.

TLDR
The cumulative evidence suggests that individuals with MS are less physically active than nondiseased, but not diseased, populations.
Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine
TLDR
It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis.
Quantification of walking mobility in neurological disorders.
TLDR
Impaired walking can be a marker of both disability and disease progression, and is therefore an important outcome measure in the treatment and rehabilitation of diseases such as MS and Parkinson's disease (PD).
Cognitive dysfunction in multiple sclerosis: a review of recent developments.
TLDR
This area of research has suggested that disease modifying medications can have an impact on magnetic resonance imaging disease activity by altering the cerebral demyelinating process resulting in a slower decline in cognitive functions over time and improved activities of daily living for patients with multiple sclerosis.
