STI II: Unit 3 and 4 Exam Questions with Verified Answers (Correct
Update)
Question 1: 4 stages of scar formation
Answer: - Inflammatory phase - Granulation phase - Fibroblastic phase - Maturation phase
Question 2: Inflammatory
Answer: - 24-48 hours - heat, redness, swelling, pain - histamine released - prostaglandins produce
pain - phagocytosis to prevent infection - macrophages appear and influence scar production
Question 3: Granulation
Answer: - macrophages and histiocytes debride the area - heat application may cause increased
bleeding
Question 4: Fibroblastic
Answer: - fibroblasts proliferate and collagen synthesis is accelerated - 5-8 days high metabolic
activity
Question 5: Maturation or re-modeling
Answer: - 3 wks- 12 months - Collagen change in order to reach max function - Physical change in
scar length - scar tissue responsive to manual therapy
Question 6: What is the best treatment strate-gy for each phase of scar forma-tion?
Answer: -clow load long duration controlled stress and manual therapy

, Question 7: What is the differ- -ence between the the fibrotic process and scar forma-tion
process?
Answer: Fibrotic process is cyclical, homogenous process in connective tissue involving entire
tissue area - this process can continue as long as the irritant is present. Scar tissue formation has a
linear process having a distinct end
Question 8: Non-traumatized connective tissue
Answer: - no contracture occurs due to no catalyst - significant gorund substance loss with no
collagen loss - decrease in tissue extensibility
Question 9: Traumatized con-nective tissue
Answer: - joint contractures occur with immobilization in the presence of inflammatory exudate-
shortening of connective tissues - traumatic exudate causes fibrotic changes - possibly not gain
functional ROM in back in therapy
Question 10: Clinical implica-tions concerning traumetized con-nective tissue
Answer: - Combination of scar formation and fibrosis - scar formation occurs in areas that
sustained direct insult and are in need of regeneration and repair - fibrotic changes occur in tissues
surrounding the scar area that were not directly traumatized but were attected chemically by the
traumatic exudates - Traumatic exudates infiltrate non traumatized ares and, acting as chemical
cata-lysts, create changes in the CT
Question 11: Primary effects of -tissue mobiliza-tion: Blood flow and temperature
Answer: massage causes capillaries to dilate in the region underlying the massage - of capillary
dilation occurs, increased blood volume and flow occur, resulting in an increased temperature in
the area of the massage
