Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
Work and Energy for Variable Forces01:10

Work and Energy for Variable Forces

When an object is acted upon by a variable force, the amount of work done and the change in energy of the object can be more complex to calculate compared to when a constant force is applied. Work is the product of force and displacement, while energy is the capacity of a system to do work. When a constant force is applied to an object, the work done can be calculated as the product of the force and the distance moved in the direction of the force. However, when a variable force is applied, the...
Muscles that Move the Forearm01:16

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
Virtual Work01:20

Virtual Work

The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
Mechanical Systems01:22

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically described...

Summary

Workers with hand-arm vibration syndrome (HAVS) report significant upper extremity disability using the Disabilities of the Arm, Shoulder and Hand work module (DASH-W) questionnaire. Upper extremity pain significantly impacts DASH-W scores in HAVS patients.

Area of Science:

  • Occupational Health
  • Musculoskeletal Disorders
  • Vibration-Induced Injuries

Background:

  • The Disabilities of the Arm, Shoulder and Hand work module (DASH-W) questionnaire is a validated tool for assessing upper extremity disability.
  • Hand-arm vibration syndrome (HAVS) is a common occupational neurovascular disorder.
  • The utility of the DASH-W questionnaire in quantifying work-related disability in HAVS patients has not been previously established.

Purpose of the Study:

  • To evaluate work-related disability in HAVS patients using the DASH-W questionnaire.
  • To identify the specific components of HAVS that contribute to DASH-W scores.

Main Methods:

  • A cohort of 139 workers diagnosed with HAVS from diverse industries was assessed.
  • Participants completed the DASH-W questionnaire and underwent clinical evaluation for Stockholm sensorineural and vascular stages and upper extremity pain (Borg scale).
  • Multiple linear regression analysis was employed to determine the association between HAVS components and DASH-W scores.

Main Results:

  • HAVS patients exhibited significantly higher mean DASH-W scores (54.7) compared to the general US population (P < 0.001).
  • The Stockholm sensorineural stage (P < 0.05) and upper extremity pain score (P < 0.001) were significant predictors of DASH-W scores.
  • Upper extremity pain demonstrated the highest partial R-squared value, indicating its substantial contribution to disability.

Conclusions:

  • The DASH-W questionnaire effectively measures significant upper extremity work-related disability in individuals with HAVS.
  • Upper extremity pain is a primary driver of disability reported by HAVS patients on the DASH-W questionnaire.
