Assessment of the Cardiovascular System III: Palpation01:27

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Assessment of the Cardiovascular System II: Inspection01:29

Assessment of the Cardiovascular System II: Inspection

Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Summary

College students experiencing computer-related pain should evaluate their computing patterns. Frequent, longer breaks, especially stretching breaks, are associated with fewer upper extremity musculoskeletal symptoms.

Area of Science:

  • Ergonomics
  • Occupational Health
  • Musculoskeletal Disorders

Background:

  • Over 50% of college students report pain linked to computer use.
  • Upper extremity musculoskeletal symptoms are a common complaint among students.

Purpose of the Study:

  • To investigate the relationship between computer use patterns and upper extremity musculoskeletal symptoms in college students.
  • To determine if break frequency and duration influence symptom experience.

Main Methods:

  • 30 undergraduate students tracked symptom experiences and computing/break patterns over three weeks.
  • Logistic regression models analyzed daily associations between computing patterns and symptom occurrence.
  • Adjustments were made for relevant covariates.

Main Results:

  • Increased computer use duration and more frequent/longer breaks (especially stretch breaks) were linked to higher odds of experiencing any or moderate/greater symptoms.
  • Breaks under 15 minutes showed a negative association with experiencing any symptoms.
  • Specific break patterns (e.g., 3-6 breaks, >15 min breaks) significantly correlated with symptom prevalence.

Conclusions:

  • Computing and break patterns are significantly associated with upper extremity musculoskeletal symptoms in students.
  • Assessing break strategies alongside computing duration provides more insight than duration alone.
  • Findings can inform the design of ergonomic training programs for student populations.
