Hand hygiene

6.0K
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

2.6K
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...

The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

285
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

214
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Summary

Contact guarding (CG) and standby guarding (SG) do not significantly impact Functional Gait Assessment (FGA) scores in older adults. Experienced physical therapists ensure consistent performance regardless of the guarding method used during fall risk assessment.

Area of Science:

  • Gerontology
  • Physical Therapy
  • Biomechanics

Background:

  • Accurate fall risk assessment is crucial for fall prevention strategies in older adults.
  • Potential for falls during assessment necessitates effective guarding methods.
  • Disagreement exists regarding the optimal guarding technique for fall risk assessments.

Purpose of the Study:

  • To compare the impact of contact guarding (CG) and standby guarding (SG) on Functional Gait Assessment (FGA) performance.
  • To determine if different guarding methods influence FGA scores.
  • To assess participant perception of CG versus SG.

Main Methods:

  • A within-subjects design was employed with 23 community-dwelling older adults (mean age 73.6 years).
  • Each participant completed two FGA trials: one with CG and one with SG.
  • Trials were conducted by a single experienced physical therapist and video-recorded for blinded rater analysis.

Main Results:

  • High inter-rater reliability was observed for both CG (ICC = 0.949) and SG (ICC = 0.935) conditions.
  • No significant difference was found in FGA scores between CG and SG (t22 = 0.15, P = .882).
  • Participants did not report any perceived difference between the two guarding methods.

Conclusions:

  • Hands-on guarding (CG or SG) does not significantly alter FGA performance in community-dwelling older adults.
  • The experience of the physical therapist is a key factor in maintaining consistent assessment outcomes.
  • Findings support the use of either CG or SG by experienced PTs for reliable fall risk assessment.
