Preliminary efficacy of the "SitLess with MS" intervention for changing sedentary behaviour, symptoms, and physical performance in multiple sclerosis.

Purpose: People with multiple sclerosis (MS) sit (i.e., are sedentary) more than peers.

The SitLess With MS Program: Intervention Feasibility and Change in Sedentary Behavior.

Objectives: This study reports on the feasibility of the SitLess with MS trial, an intervention targeting sedentary behavior in individuals with multiple sclerosis (MS).

Design: Single group, pre-post intervention design.

Setting: Community.

Management of multiple sclerosis symptoms through reductions in sedentary behaviour: protocol for a feasibility study.

Introduction: People with multiple sclerosis (MS) are less physically active, and more sedentary than their peers despite evidence that activity helps to manage MS-related symptoms. Traditional approaches to increasing physical activity, such as exercise programmes, can be challenging for people with MS, especially those with walking disability. Focusing on decreasing prolonged sitting, and increasing light-intensity activities may be more feasible and result in more sustainable behaviour change in persons with MS.

Sit less and move more: perspectives of adults with multiple sclerosis.

Purpose: Multiple sclerosis is a chronic neurological disease with the highest prevalence in Canada. Replacing sedentary behavior with light activities may be a feasible approach to manage multiple sclerosis symptoms. This study explored the perspectives of adults with multiple sclerosis about sedentary behavior, physical activity and ways to change behavior.

Standing Classrooms: Research and Lessons Learned from Around the World.

Children spend between 50 and 70 % of their time sitting while at school. Independent of physical activity levels, prolonged sitting is associated with poor health outcomes in adulthood. While there is mixed evidence of health associations among children and adolescents, public health guidelines in the USA, UK, Australia and Canada now recommend young people should break up long periods of sitting as frequently as possible.

Week-to-week differences of children's habitual activity and postural allocation as measured by the ActivPAL monitor.

Background: Quantification of sitting and standing is possible with the ActivPAL accelerometer, using algorithms to classify activity into time spent sitting, standing and stepping. The purpose of this study was to determine children's week-to-week differences in time spent sitting/lying and standing along with other measures as provided by the ActivPAL accelerometer during continuous wearing of the ActivPAL monitor.

Methods: Fifty-six children (age 10.

Acceptability of standing workstations in elementary schools: a pilot study.

Objective: To examine the acceptability of introducing standing workstations in elementary-school classrooms; and to quantify changes in children's time spent sitting, standing, and walking; step counts; sit-to-stand transitions; and musculoskeletal discomfort.

Methods: A controlled trial was conducted in two elementary schools in Auckland, New Zealand (March-May 2012). Participants were 30 third and fourth graders (n = 23 intervention, n = 7 control).

Examining the validity of the ActivPAL monitor in measuring posture and ambulatory movement in children.

Background: Decreasing sedentary activities that involve prolonged sitting may be an important strategy to reduce obesity and other physical and psychosocial health problems in children. The first step to understanding the effect of sedentary activities on children's health is to objectively assess these activities with a valid measurement tool.

Purpose: To examine the validity of the ActivPAL monitor in measuring sitting/lying, standing, and walking time, transition counts and step counts in children in a laboratory setting.
