Joints01:26

Joints

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

Method of Joints01:30

Method of Joints

The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...
Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
Skeletal Muscle Anatomy00:55

Skeletal Muscle Anatomy

Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Muscle Contraction01:10

Muscle Contraction

In skeletal muscles, acetylcholine is released by nerve terminals at the motor endplate—the point of synaptic communication between motor neurons and muscle fibers. The binding of acetylcholine to its receptors on the sarcolemma allows entry of sodium ions into the cell and triggers an action potential in the muscle cell. Thus, electrical signals from the brain are transmitted to the muscle. Subsequently, the enzyme acetylcholinesterase breaks down acetylcholine to prevent excessive muscle...

Summary
This summary is machine-generated.

Nursing textbooks lack comprehensive information on joint contracture prevention and treatment, despite controversies in healthcare. Current literature fails to address the scientific uncertainties surrounding this common nursing issue.

Area of Science:

  • Nursing Science
  • Rehabilitation Medicine

Context:

  • German statutory health insurance transparency criteria have sparked debate regarding joint contracture assessment, prevention, and treatment.
  • Nursing practice has seen varied responses, yet lacks standardized assessments and evidence-based interventions.
  • Existing nursing textbooks may not adequately reflect these clinical uncertainties.

Purpose:

  • To evaluate the content of nursing textbooks concerning joint contractures.
  • To determine if current nursing literature addresses the scientific gaps in joint contracture assessment and management.

Summary:

  • A review of 35 nursing textbooks identified definitions in 25 and causes/risk factors in 32, but only 5 included assessment details.
  • Passive prophylaxis commonly recommended includes neutral positioning and passive limb movement.
  • Textbooks do not acknowledge the existing lack of scientific evidence for recommended interventions.

Impact:

  • Nursing education and practice may be based on incomplete or outdated information regarding joint contractures.
  • Highlights the need for updated nursing curricula and evidence-based guidelines for joint contracture management.
  • Underscores the gap between clinical controversies and the scientific information presented in educational materials.
