The purpose of this study was to determine whether low doses of carbon monoxide (CO) exacerbate myocardial ischemia during a progressive exercise test. The effect of CO exposure was evaluated using the objective measure of time to development of electrocardiographic changes indicative of ischemia and the subjective measure of time to onset of angina.… (More)
General agreement among researchers suggests that poor seating posture may predispose individuals to developing low back pain. A variety of methods such as ergonomically designed chairs have been developed to assist people to maintain good posture and preserve the 'natural' lumbar curve. The aim of this study was to compare lumbar curvature on an… (More)
BACKGROUND AND PURPOSE Assessment of spinal posture during physiotherapy practice is routine, yet few objective measures exist to this end. The Middlesbrough Integrated Digital Assessment System (MIDAS) is a low cost portable system able to record 3D information on posture. The purpose of this study was to assess both the intra-rater and inter-rater… (More)
UNLABELLED Regular carriage of heavy loads such as backpacks, satchels and mailbags results in a variety of acute medical problems and increased potential for back injury. There is a paucity of information about the specific changes in back posture that occur in response to asymmetrical loading. The purpose of this study was to examine the changes in back… (More)
Objectives The primary objective of this study was to evaluate the relationship between spinal curvature and postural sway in the frontal and sagittal planes in asymptomatic young adults. A secondary objective was to look at this relationship over a time period of 15 minutes.
Objectives The primary objective of this study was to produce a database of normative sagittal values of the spine in young adult subjects, against which the spines of patients with different spinal dysfunctions could be compared.
Objectives The purpose of this study was to evaluate the effect of seating type on sitting posture through comparison of a modified desk chair and a stability ball in the sagittal plane over a duration of 30 minutes. The usability of the stability ball was assessed through the completion of a purposely designed questionnaire.
UNLABELLED Whilst postural evaluation of spinal dysfunction is routine in physiotherapy practice, objective measurements are rarely undertaken due to the scarcity of reliable low cost assessment tools. Warren et al  found high intrarater reliability but inter-rater reliability has not as yet been evaluated. The purpose of this study was to assess both… (More)
The reliability and accuracy in the measurement of landmark points using a 3-D digitizer on a static back phantom are reported. The results show the systems clinical reliability as a low cost, portable and flexible method for recording back posture. Consistent results are demonstrated for a single measurer and good agreement was found between two measurers.… (More)
