Q

Explain scapulohumeral rhythm.

A

the glenohumeral joint (GHJ) and scapulothoracic joint (ST) move in a 2:1 ratio.

When the arm is abducted 180 degrees, 60 degrees occurs by rotation of the ST, and 120 degrees by abduction of the GHJ.

First 30 degrees of abduction largely occurs at GHJ.

30 degrees on, GHJ & ST joint move simultaneously

62
Describe the elements of the LOVE principle and briefly describe each?
L – load Mechanical stress should occur early, and normal activities resumed as soon as practical. Optimal loading without exacerbating pain promotes repair, remodelling and builds tissue tolerance O – optimism Condition your brain for optimal recovery by being confident and positive. V – vascularisation Choose pain free cardiovascular (aerobic) activities to increase blood flow to repairing tissues E – exercise Restore mobility, strength and proprioception by adopting an active approach to recovery.
63

* Grade I: Mild strain, minimal fiber disruption * Grade II: Moderate strain, partial tear * Grade III: Severe strain, complete tear
64
Describe 5 types of fractures and briefly describe them?
Transverse Fracture * Breaks that are in a straight line across the bone. Greenstick Fracture * Partial fracture * Bone bends and breaks but does not separate into two separate pieces. Oblique Fracture * Break is diagonal across the bone. Compression Fracture * When bone is crushed. Osteoporosis most common cause Spiral Fracture * Fracture that spirals around the bone.
65
List factors that may contribute to delays in healing?
Local Factors: Infection: * Bacteria or other pathogens can disrupt the healing process and prolong inflammation. Movement or Re-injury: * Excessive movement or re-injury at the healing site can disrupt tissue repair and delay healing. Poor Wound Care: * Inadequate wound care or improper dressing can impede healing and promote infection. Systemic Factors: Age: * Healing tends to be slower in older individuals due to decreased cell turnover and reduced immune function. Smoking: * Smoking constricts blood vessels and reduces oxygen delivery to tissues, impairing healing. Medications: * Certain medications, like chemotherapy drugs, can suppress the immune system and delay healing.
66
What are some of the processes that occur in each phase of healing?
Inflammatory phase Hematoma Formation: Blood clot forms, aiding repair. Inflammation: Increased blood flow, swelling, redness, and pain. repair phase Fibroblast Migration & Proliferation: Fibroblasts produce collagen at the injury site. Angiogenesis: New blood vessels form to supply nutrients. remodelling phase Scar Maturation: Scar tissue remodels, collagen fibers align and strengthen. Tissue Strengthening: Repaired tissue gains strength and function with proper loading and exercise.
