Purpose: To develop and test decision tree (DT) models to classify physical activity (PA) intensity from accelerometer output and Gross Motor Function Classification System (GMFCS) classification level in ambulatory youth with cerebral palsy (CP) and compare the classification accuracy of the new DT models to that achieved by previously published ...
Aim: To determine the efficacy of web-based training on activity capacity and performance in children with unilateral cerebral palsy (CP). Method: In a matched-pairs randomized waitlist controlled trial, independently ambulant children and adolescents with unilateral CP were allocated to receive 30 minutes of training (intervention) 6 days per week, or usual care (...
Aims: Develop and test decision tree (DT) models to classify physical activity (PA) intensity from accelerometer output and Gross Motor Function Classification System (GMFCS) level in ambulatory youth with CP; and 2) compare the classification accuracy of the decision tree models to that achieved by previously published cut-points for youth with ...
Purpose: Objective and subjective quantification of habitual physical activity (HPA) and sedentary time in ambulatory and nonambulatory adults with cerebral palsy (CP). Methods: We recruited a clinical sample of adults with CP (N=42; 21 female; mean age: 33.5 yr, SD 12.3 yr; Gross Motor Function Classification System (GMFCS) distribution: Level I (n=5), Level ...
Objective: To study physical behavior (PB) in detail in fatigued persons with multiple sclerosis (MS). Design: case-control explorative study. Setting: Outpatient rehabilitation department. PB monitoring was conducted in participants' daily environment. Participants: Twenty-three fatigued persons with MS were selected from an RCT. Cases were matched to, 23 age- and gender-matched healthy, ...
Introduction: To establish the variability in the measurement of habitual physical activity (HPA) using the ActiGraph(R) GT3X+ accelerometer in children with cerebral palsy (CP). Method: Repeated measures: Independently ambulant children with unilateral CP (n=30; aged 11y3m [2y4m]) completed standardized tasks over two consecutive days wearing an ...
Background: Researchers have recently advocated for the 2-minute walk (2MW) as an alternative for the 6-minute walk (6MW) to assess long distance ambulation in persons with multiple sclerosis (MS). This recommendation has not been based on physiological considerations such as the rate of oxygen consumption (V·O2) over the 6MW ...
Abstract: The impairment of cognitive processing speed is common, disabling, and poorly managed in multiple sclerosis (MS). This study examined the association between objectively-measured physical activity and cognitive processing speed (CPS) in a large sample of persons with MS. Patients (N=212) underwent two valid neuropsychological tests of CPS, completed the ...
Objective: Motion sensors such as accelerometers have been recognized as an ideal measure of physical activity in persons with MS. This study examined the hypothesis that accelerometer movement counts represent a measure of both physical activity and walking mobility in individuals with MS. Methods: The sample included 269 individuals with a ...
Abstract: Accelerometry has been recognized as a method of objectively measuring community ambulation in persons with multiple sclerosis (MS). However, the assumption that walking itself serves as a major contributor to the accelerometer signal has yet to be tested. This study examined the assumption that community-based walking is a primary ...
