Physical Pendulum

When a rigid body is hanging freely from a fixed pivot point and is displaced, it oscillates similar to a simple pendulum and is known as a physical pendulum. The period and angular frequency of a physical pendulum are obtained by using the small-angle approximation and drawing parallels with a spring-mass system. The small-angle approximation (sinθ=θ) is valid up to about 14°.
When dealing with complicated systems, the mass moment of inertia is an important parameter, as it...

The 4 M’s Framework: Case History and Physical Examination of Older Adults

Source: Jennifer A. Ouellet and Jaideep Talwalkar; Yale School of Medicine
To meet the needs of older adults, all health professionals should be well acquainted with the history and physical examination considerations unique to this population. Physical examination plays an important role in the older patient to detect physiologic changes of aging, risk factors, and signs of pathology. While most of the general principles of the standard examination for adults apply to older patients,...

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...

Observational Study Protocol for Repeated Clinical Examination and Critical Care Ultrasonography Within the Simple Intensive Care Studies10:38

Observational Study Protocol for Repeated Clinical Examination and Critical Care Ultrasonography Within the Simple Intensive Care Studies

Structured protocols are necessary to provide answers on research questions in critically ill patients. The Simple Intensive Care Studies (SICS) provides an infrastructure for repeated measurements in critically ill patients including clinical examination, biochemical analysis and ultrasonography. SICS projects have specific focus but the structure is flexible to other investigations.

Using Point of Care Ultrasound to Augment Acquisition of Physical Exam Skills: Veins and Arteries

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA
Vascular diseases make up most cases of emergency hospitalization and carry a high mortality risk. Point-of-care ultrasound or POCUS enables accurate diagnosis of these diseases and shortens the time between detection of the cause and selection of appropriate treatment strategies, thus, reducing the patient mortality rate. POCUS offers a safe, low-cost, and less invasive bedside tool for examining arteries and veins, besides its...

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA
Point of care ultrasound (POCUS) is used by clinicians for diagnosis, ongoing monitoring, and/or procedural guidance at the time of patient care. Many medical schools are now teaching POCUS as a part of their basic clinical skills training, in addition to history, physical exams, and clinical reasoning. Besides being an independent skill, POCUS is also an incredibly useful tool for augmenting the teaching and learning of the...
