IASTM

Question 1

neurophysiological effects of IASTM

Answer 1

• reduced muscle guarding/spasm
• pain reduction
• muscular facilitation/altered muscle recruitment and increased force production
• improve proprioception
• improved nerve conduction latency

Question 2

Mechanotransduction

Answer 2

• Shearing and compression stimulate fibroblastic activity
• increased production of fibronectin
• proliferation and maturation of fibroblasts
• replacement of type III collagen to type I
• change in substance P distribution

Question 3

how does IASTM change fluid dynamics

Answer 3

may increase regional perfusion and vascularity

Question 4

fundamentals of IASTM

Answer 4

• treats all tissues
• consider functional movement patters
• manual skills are foundation
• tools are extension of PT hands not replacement
• if you wouldn’t treat it with your hands, dont do it
• goal targeted treatment
• manual skill that requires development

Question 5

precautions

Answer 5

• anticoagulants
• dont treat over varicosities
• diabetes
• high irritability/ increases sx
• auto immune disorder
• CRPS
• surgically repaired tissue

Question 6

contraindications

Answer 6

• patient issues
• infection
• hematoma
• recent fracture
• osteomyelitis
• thrombophlebitis
• open wounds
• skin conditions

Question 7

what dictates the type of IASTM

Answer 7

shape of tissue

Question 8

concave

Answer 8

disperse force

Question 9

convex

Answer 9

focus force

Question 10

what should you always begin with

Answer 10

tissue scan

Question 11

how can force be varied

Answer 11

• changing treatment angle
• 30-60 degrees typical
• lower angle is more superficial

Question 12

if patient is not tolerating treatment, you can change:

Answer 12

• angle
• force
• bevel diration
• size of instrument
• tool surface (concave)

Question 13

Treatment sequence

Answer 13

• warm up
• IASTM/ manual therapy with pre/post test
• therapeutic exercise

Question 14

scanning stroke

Answer 14

identifies tissue restrictions
- 2 handed, parallel to fibers

Question 15

sweeping stroke

Answer 15

• 2 handed, parallel to fibers
• can be proximal to distal or distal to proximal

Question 16

fanning stroke

Answer 16

1 handed arc movement

Question 17

strumming stroke

Answer 17

• like deep cross friction massage but very short stroke like always in one direction only
• tool angle sharper (typically 45-70 degrees)

Question 18

brushing stroke

Answer 18

short strokes of similar length with smaller treatment edge

Question 19

J stroke

Answer 19

• lift the edge
• useful for focal treatment of restriction

Question 20

Framing stroke

Answer 20

short stroke around superficial bony contours
