Week 10-Posture/Flexibility

Question 1

Posture - Pathology/Injury?

Answer 1

Spine alignment

Question 2

Evolutionary Changes to Posture?

Answer 2

‘C’ shaped spine to an ‘S’ shape (bridge to pole)

Question 3

Good’ Posture?

Answer 3

1. Line of gravity runs through joints
2. Minimal muscular energy requirement
3. Also less stress to surrounding tissues

Question 4

‘Poor’ Posture?

Answer 4

1. Line of gravity outside of joint centres

2. Requires muscular effort

Question 5

Computer posture?

Answer 5

Shortens pectoralis

Lengthens erector spinae

Question 6

Overcompensation?

Answer 6

Movement is required for shock absorption
Foot arches
Synergistic pelvic movements

Question 7

Trunk Muscles?

Answer 7

Will provide some movement and skeleton allows ROM

Question 8

Postural Defects?

Answer 8

Injury - weak
Disease - arthritis
Asymmetry and Imbalance - scoliosis
Habit

Question 9

Postural Defects?

Answer 9

Defect in one area results in accommodation in another (two wrongs don’t make a right!)

Question 10

Anteroposterior defects?

Answer 10

Poked or forward head
Kyphosis
Lordosis

Question 11

Postural Assessment?

Answer 11

Basic method for identifying postural deficiencies

Attempt to identify large deviations
from ‘normal’

Question 12

Dynamic Postural Assessment?

Answer 12

Dynamic tasks may expose functional postural limitations

Question 13

Muscle/Tendon Elasticity - Fibrous tissue (Passive stiffness)?

Answer 13

perimysium – parallel elastic component

epimysium, tendon – series elastic component

Question 14

Mechanical Responses of MTU to Stretch?

Answer 14

Force relaxation
Creep (length change)
Hysteresis (energy retained)

Question 15

Types of stretching?

Answer 15

Passive (Static/partner)

Active (Dynamic Stretching/Ballistic Stretching)

Question 16

PNF Neurological Mechanisms?

Answer 16

Inverse stretch reflex

Reciprocal inhibition
