Internal control activities form the operational backbone of a company’s efforts to safeguard assets, improve financial accuracy, and reduce the likelihood of errors or fraud. These activities translate broad control goals into specific, actionable practices that support day-to-day integrity in business processes. The six principles of internal control activities, as highlighted in the COSO framework and widely recognized accounting standards, play a vital role in building robust systems.Key...

Assessment of Physical Activity Intensity with Accelerometers and Oxygen Consumption

2025
Here, we present a protocol to assess physical activity intensity levels measured with indirect calorimetry and two accelerometers (on the right wrist and waist) during an incremental walking-jogging test (from 0.84 to 2.37 m/s) on an oval track. The results show differences among the physical intensity assessed through those methods.

Since the Roman Empire, physicians have described the connection between alterations in function of specific parts of the body and specific disease states and have sought to further scientific understanding to improve bedside diagnosis. However, in this modern age of increasing technology within medical diagnostics, it...

Talwalkar, MD, and Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT In order to optimize the predictive value of the physical examination, the provider must perform maneuvers correctly. The proper use of drapes is an important component of correctly performing physical examination maneuvers. Skin lesions are missed when "inspection" occurs through clothing, crackles are erroneously reported when the lungs are examined through a...

This protocol describes confocal microscopy detection of G protein-coupled receptor (GPCR) internalization in mammalian cells. It includes the basic cell culture, transfection, and confocal microscopy procedure and provides an efficient and easily interpretable method to detect the subcellular localization and internalization of fusion-expressed GPCR.
FAQs
The questionnaire separates reported activity into work, transportation, household, and leisure domains, then captures frequency, duration, and intensity within those areas. This structure helps distinguish where activity occurs rather than treating all movement as a single undifferentiated measure. In medical research, domain-specific results can support comparisons of lifestyle patterns across groups or study populations.
The seven-day recall period creates a consistent time window for describing recent activity and sedentary behavior. Participants report their experiences over the same preceding interval, allowing researchers to summarize responses using a common reference period. This approach supports comparisons between participants and helps investigators examine activity patterns during the period relevant to a study.
IPAQ responses are converted into metabolic equivalent of task minutes per week, or MET-min/week, by combining the reported activity dimensions captured by the instrument: frequency, duration, and intensity. The resulting value provides a standardized summary of weekly activity. Researchers can then use that summary to examine differences in overall activity across participants or populations.
Classifying overall activity levels turns the questionnaire’s reported behavior into broader activity categories that can be used in analysis. Rather than relying only on separate reports of duration or intensity, researchers can compare participants according to their overall activity status. In medicine, these categories help evaluate lifestyle-related health risks and describe patterns within population health studies.
A participant should recall activity during the previous seven days and report how often and how long activities occurred, together with their intensity. Responses should account for work, transportation, household, and leisure activities, as well as sedentary behavior. Collecting these elements gives investigators the information needed to summarize activity consistently across the questionnaire’s domains.
The IPAQ is useful when investigators need a standardized way to assess physical activity and sedentary behavior in clinical or population health research. It can support evaluation of lifestyle-related health risks, comparison of activity across populations, and assessment of physical activity interventions. Researchers may also use the resulting measures when examining relationships between activity patterns and chronic disease outcomes.
Investigators can administer the questionnaire to describe participants’ activity and sedentary behavior in relation to an intervention study. Responses summarized as MET-min/week or activity classifications provide outcomes for comparing activity patterns within the research design. This makes the instrument relevant for examining whether an intervention is associated with changes in reported physical activity across the assessed population.
Physical activity and sedentary behavior are lifestyle measures that can be examined alongside health risks and chronic disease outcomes. The IPAQ supplies standardized summaries that allow medical researchers to compare activity patterns among populations and connect those patterns with broader health research questions. Its use also supports clinical and population-level studies focused on lifestyle assessment and intervention evaluation.
