BACKGROUND The accurate measurement of physical activity is crucial to understanding the relationship between physical activity and disease prevention and treatment. OBJECTIVE The primary purpose of this study was to investigate the validity and reliability of the activPAL physical activity monitor in measuring step number and cadence. METHODS The(More)
The purpose of this study was to develop and test a generic technique to robustly quantify the pattern of sedentary behaviour from objective records. The technique was applied to four groups of subjects: a healthy group with an active occupation (N=54), a healthy group with a sedentary occupation (N=53), a group of subjects with chronic low back pain (N=5)(More)
BACKGROUND Accurate measurement of physical activity patterns can be used to identify sedentary behaviour and may facilitate interventions aimed at reducing inactivity. OBJECTIVE To evaluate the activPAL physical activity monitor as a measure of posture and motion in everyday activities using observational analysis as the criterion standard. METHODS(More)
BACKGROUND AND PURPOSE It has been suggested that cyclic neuromuscular electrical stimulation (ES) may enhance motor recovery after stroke. We have investigated the effects of ES of the wrist extensors on impairment of wrist function and on upper-limb disability in patients being rehabilitated after acute stroke. METHODS We recruited 60 hemiparetic(More)
The primary purpose of this study was to investigate the accuracy of the activPAL physical activity monitor in measuring step number and cadence in older adults. Two pedometers (New-Lifestyles Digi-Walker SW-200 and New-Lifestyles NL2000) used in clinical practice to count steps were simultaneously evaluated. Observation was the criterion measure.(More)
The aim of this single-blind pilot RCT was to investigate the effect of pain biology education and group exercise classes compared to pain biology education alone for individuals with chronic low back pain (CLBP). Participants with CLBP were randomised to a pain biology education and group exercise classes group (EDEX) [n = 20] or a pain biology education(More)
OBJECTIVE To develop and evaluate a system for the objective measurement of upper-limb activity during a person's activities of daily living. DESIGN Construct validation study. SETTING Home and work environment. PARTICIPANTS Ten able-bodied participants and 10 stroke patients. INTERVENTIONS A novel activity monitor was developed for monitoring(More)
BACKGROUND Contractures are common in a stroke population, yet there is little information on the time course of development. OBJECTIVES Investigate quantitatively changes associated with contracture formation in an acute stroke population. STUDY DESIGN Longitudinal study on 22 subjects who were 2-4 weeks post stroke. OUTCOME MEASURES Contractures(More)
OBJECTIVES To develop a new method of representing energy expenditure using heart rate and to determine its reproducibility compared with the criterion standard of oxygen cost. DESIGN Repeated-measures design. SETTING University gait analysis laboratory and gymnasium at 2 spinal injury units. PARTICIPANTS Twenty unimpaired adults and 17 subjects with(More)
