67
Q

What happens along with right heel strike?

  • right innominate posterior rotation
68
Q

What happens along with right foot flat to mid-stance?

A
  • right hip extension begins with right innominate anterior rotation
  • right hip internal rotation and adduction as pelvis begins to rotate right on right femur
  • eccentric then isometric right hip abductors and external rotators for right unilateral stance
69
Q

What happens along with right heel off to toe-off?

A
  • right hip extension, abduction and internal rotation
  • maximal potential energy occurs in lengthened right hip capsule/ligaments and hip flexors
  • right psoas lengthening further assists with trunk right side bend, extension and left rotation if T10 rotation WNL
70
Q

What happens along with right acceleration to mid-swing?

A
  • release of lengthened capsule, ligament, and psoas creating hip flexion
71
Q

What are the three storehouses of potential energy?

A
  1. non- contractile tissue
  2. contractile tissue
  3. T10 rotation allows psoas to assist with trunk motion and early and mid-swing of LE - like upper T-spine motion with lower trap
72
Q

What is a example of non-contractile tissue as a storehouse of potential energy?

A

hip capsule and ligaments lengthen with hyperextension

73
Q

What is an example of contractile tissue as a storehouse of potential energy?

A

hip flexors lengthen, particularly psoas and iliocapsularis

74
Q

IF we dont maintain out base of support, we _____

75
Q

If we cant transfer energy, we become ___________

A

Inefficient

76
Q

What do excessive ground reaction or landing forces lead to?

A

traumatic or repetitive stress injury

77
Q

What does more friction generate?

A

additional heat (blisters) and prevents motion (trauma)

78
Q

What does a lack of stored potential energy of lengthened muscles, ligaments and capsules contribute to?

A

Repetitive stress of overuse injury

79
Q

What are some characteristics of LE induced (NOT TRUNK) walking?

A
  • no give so increased impact
  • spinning on the ball of the foot (increased friction)
  • actively advancing non-WB LE
  • trunk follows the leading LE
80
Q

is LE induced walking efficient? Effective?

A

Effective yes, efficient no

81
Q

What is a primary driver of gait?

82
Q

What is NOT essential for locomotion?

A

Extremities

83
Q

Can we still walk without extremities?

A
  • still walk without arm swing
  • we can locomote while long sitting
84
Q

What do the extremities provide with locomotion?

A

extra leverage and energy savings for more efficient gait

85
Q

What are the functional goals with optimal human gait? (basic)

A
  • minimize impact and friction
  • maximize PE
86
Q

We want to be ________ not just ___________

A

efficient not just effective

87
Q

What can effectiveness derive from?

A

Compensations

88
Q

What do compensations during gait do?

A

decrease efficiency and expend NOT only more but likely the wrong injury = injury

89
Q

What are common areas of excessive stress if storehouses of potential energy do NOT occur?

A
  • hip joint
  • hip flexor overuse
  • lower lumbar spine under more stress
90
Q

Why is the hip joint a common area of excessive stress if storehouses of potential energy do NOT occur

A

decreased cartilage integrity by limited motion

91
Q

Why is hip flexor overuse a common area of excessive stress if storehouses of potential energy do NOT occur?

A

with shorter strides
- due to increased active hip flexion
- demonstrated with iliocapsulatis

92
Q

Why is the lumbar spine a common area of excessive stress if storehouses of potential energy do NOT occur?

A
  • with lack of T10 rotation and / or hip hyperextension
93
Q

What are some functional tests for return to sport or pre-sport screening?

A

Quantity and Quality
- limb symmetry
- agility tests

94
Q

What should we know about functional tests with hip pathologies?

A

Not studied

95
Q

What is a functional test for predicting LE basketball injury?

A

SEBT (star excursion balance test)
- looking for asymmetry or pain

96
Q

What is the single limb squat test looking for?

A

asymmetry or pain

97
Q

What is the FMS (functional movement screen) used for?

A

to predict non-contact injury

98
Q

What are the unilateral and bilateral hop tests? What are they used for?

A
  • cross over
  • 3 hop forward and lateral
  • normative and biological sex values in young athletes
  • acceptable threshold ≥ 90% of uninvolved developed with ACL injuries
99
Q

What are some other jump tests that can be used as a functional test for hip pathology?

A
  • Drop vertical jump
  • Tuck jump
100
Q

What are agility tests used for with hip pathologies? What is a con?

A
  • may have value in athletic population because of sport specific testing

CON
- not able to discriminate between injured and non-injured limbs

101
Q

What is a practice progression for hip pathologies?

A
  • predictable and non-contact
  • unpredictable and non-contact
  • predictable and contact
  • unpredictable and non-contact
    may need to consider distance, time, pace, intensity, etc. as well
102
Q

What is a predictor of LE injury?

A

Hip ER weakness

103
Q

What is highly active as a stabilizer for ER especially through hip extension?

A

Piriformis
