Mechanisms of injuries

What are the types of tissues involved in injury mechanics?

Bone, cartilage, tendon, ligament, muscle.

What is the primary focus of mechanism-based diagnosis in healthcare?

Identifying specific cellular, molecular, and mechanical processes that contribute to a patient’s condition.

What does the Hippocratic Oath prioritize in patient care?

Patient safety, including treatment decisions, patient autonomy, and confidentiality.

What is the function of dense regular connective tissue?

Firm attachment of muscle to bone and reduction of friction between muscles.

What are the major components of extracellular matrix (ECM)?

Extracellular protein fibers and fluid ground substance.

What is the role of therapeutic ultrasound?

Used solely for pain relief, does not break down scar tissue.

What factors affect the strength of scar tissue?

Number and strength of crosslinks, alignment of tropocollagen, and external factors like immobilization and reinjury.

What is the major characteristic of fibrocartilage?

Densely interwoven coarse collagenous fibers arranged in bundles.

What does Evidence Based Practice (EBP) integrate into the decision-making process?

Clinical expertise, patient values, and best research evidence.

What is the anatomical position?

Standing upright, facing forward, arms at the sides, palms facing forward, feet slightly apart.

How does the alignment of tropocollagen affect collagen strength?

Alignment enhances tensile strength and supports the functionality of the tissue.

What are examples of biomarkers used in mechanism-based approaches?

Respiration, heartrate, brainwaves/electrical signals.

What is the function of elastic connective tissue?

Stabilizes vertebrae and allows for full flexion while protecting against hyperflexion injury.

What defines the function of hyaline cartilage?

Stiff but flexible support that reduces friction in joints.

What are the three types of supporting connective tissues mentioned?

Hyaline cartilage, elastic cartilage, and fibrocartilage.

Which phase of injury management focuses on optimizing collagen alignment?

Rehabilitation phase using low-load, long duration, sub-threshold force.

What are the main components of blood in terms of connective tissues?

Plasma, red blood cells (RBCs), white blood cells (WBCs).

What significant feature does compact bone present?

Bone matrix that mineralizes and consists of lamellae surrounding a central Haversian canal.

What does 'non-linear' mean in the context of complex systems?

Interactions within the system do not follow a straight forward cause-and-effect relationship.

How are clinical findings communicated to other professionals according to the physical assessment principle?

By recognizing diagnostic features of musculoskeletal injury or disease.

What are the three primary elements that inform EBP according to its definition?

Best research evidence, clinical expertise, and patient values/preferences.

What should be considered when making treatment decisions in EBP?

Integration of evidence, clinical expertise, and individual patient circumstances.

What is the characteristic of dense irregular connective tissue?

Thick collagenous fibers arranged in an interwoven mesh, providing strength in multiple directions.

What is one common misunderstanding about stretching in injury management?

Stretching should not be universally applied as it varies based on the cause of pain.
