Question 23

The pelvic floor musculature provides inferior support to:

Answer 23

the abdominal-pelvic region

Question 24

3 key functions of intra-abdominal pressure

Answer 24

• stability of spine
• relief of pressure on spine during heavy lifting
• diaphragm is key in pressure determination and/or distribution

Question 25

3 key features of the pelvic floor

Answer 25

- functions as lower core stabilizer/increases IAP - maintains continence - key in retraining core stability

Question 26

What occurs during diaphragm inspiration

Answer 26

- diaphragm flattens - rise of upper abdomen - lateral costal expansion

Question 27

What occurs during expiration of the diaphragm

Answer 27

- diaphragm rises - caudal shift in rib cage - passive process

Question 28

Lower body cross syndrome has tight _______ and weak _______

Answer 28

tight: erector spinae and iliopsoas weak: gluteus maximus and abdominal

Answer 31

L1-2, conus medullaris

Question 32

Lower quarter screen consists of these 6 test/measures

Answer 32

- dermatomes - DTR - myotomes - neural tension (SLR/slump) - consider UMN tests - vascular screening

Question 33

Osteokinematics of the lumbar spine

Answer 33

flexion extension rotation side bend/side glide

Question 34

1st law/Type 1 of the arthrokinematics: Fryette's Law of Spinal Motion

Answer 34

- spine in neutral position | - rotation and SB occur OPPOSITE directions of each other

Question 35

2nd law/Type 2 of the arthrokinematics: fryette's law of spinal motion

Answer 35

- spine flexed or extended | - rotation and SB occur in SAME direction

Question 36

3rd law/Type 3 of the arthrokinematics: fryette's law of spinal motion

Answer 36

- motion introduced in one direction will significantly reduce motion in all other directions

Answer 37

low back pain
