free-living physical activity has many applications in the
professional healthcare arena.
most obvious is due to the relationship between physical activity
and well-being. Physical inactivity is highly correlated with
morbidity. Many clinical interventions have as a primary or
secondary outcome the increase in physical activity of the
patient. For example, a hip-replacement is often performed
to relieve pain but the pain-free result of a successful operation
allows the patient to return to pre-morbid levels of activity.
In neurological rehabilitation, for example with stroke patients,
the aim is to maximise the functional recovery of the patient,
which can be measured in terms of an increase in physical
activity. Our technology can reliably record these changes
in activity level and present the outcomes in an easily understood
benefits relate specifically to the risk of cardiovascular
disease and related conditions. Both obesity and physical
inactivity are recognised as major modifiable risk factors
for coronary heart disease. Over-nutrition and physical inactivity
result in a net energy gain and consequent weight gain. Our
technology accurately records the primary physical activities
of sitting, standing and stepping providing the clinician
with an objective record of a patient's compliance with an
activity program allowing the treatment efficacy to be reviewed
and acting as a motivational record of activity targets achieved.
application of the technology is in the assessment of moderate
physical activity. Regular physical activity is believed to
confer wide-ranging health benefits including decreased risk
of cardiovascular disease and adult-onset (Type II) diabetes.
Traditionally, these health benefits have been associated
with frequent bouts of vigorous exercise but recent research
has shown that these benefits, along with reductions in blood
pressure, blood lipid profile and some cancers, can be achieved
at moderate exercise intensities. In light of these findings
public health authorities are advocating higher levels of
moderate activity in the general population.
the USA the Center for Disease Control and Prevention (CDC)
and the American College of Sports Medicine (ACSM) recommend
that every person have at least 30 minutes per day of moderate
intensity exercise on most days of the week. Also, they recommend
that this activity need not be performed at one time but could
be built up in 10-minute blocks through the day.
technology is capable of recording and identifying periods
of moderate physical activity (brisk walking) throughout the
day and providing cumulative totals of these periods allowing
the treatment compliance to be reviewed and acting as a motivational
record of activity targets achieved.
