Question

91a. Research demonstrates a relationship between knee pain and which of the following?

1. Strong hip abductors
2. Weak abdominals
3. Stiff hamstrings
4. Weak hip abductors

b. Knee valgus is commonly associated with which of the following compensations?

1. Excessive pronation of the feet
2. Weak abdominals
3. Stiff hamstrings
4. Weak hip abductors

c. Your client, William, sits for many hours each day at his computer. Which of the following compensations are you likely to observe?

1. Posterior pelvic tilt
2. Shortened hip flexors
3. Both A and B
4. None of the above

d. Your client is a professional basketball player with a 40" vertical jump and he experiences no low back or knee pain. You assess his hamstring mobility at the popliteal angle and determine that it's less than normal. What should you do?

1. Recommend exercises to strengthen his hip flexors
2. Leave his hamstrings alone
3. Recommend static stretches for his hamstrings
4. None of the above

e. During a sagittal plane postural assessment you observe anteriorly rotated shoulders. Which of the following correctives is most likely to benefit the client?

1. Stretches for the middle trapezius
2. Strengthening exercises for the pectorals
3. Stretches for the rhomboids
4. Stretches for the pectorals

f. When your client lacks dorsiflexion, which of the following compensations is common to observe during a squat?

1. Poor hip extension
2. Knee valgus
3. Excessive anterior trunk shift
4. Excessive lumbar lordosis

g. Maximal contraction of the hip extensors results in relaxation of the hip flexors. This is an example of what neural arrangement?

1. Reciprocal innervation
2. Stretch reflex
3. Reciprocal activation
4. None of the above

h. Activating the hip abductors has been shown to increase mobility of which of the following muscle groups?

1. Lats
2. Abdominals
3. Calves
4. Hamstrings

i. Iliotibial band syndrome (ITBS) is caused by which of the following?

1. Strong hip extensors
2. Stiff hamstrings
3. An overuse injury of the IT band
4. Excessive strength of the hip abductors

j. What is the optimal depth you should train your client to squat from without pain?

1. The depth required for the client's life or sport
2. A half squat since anything lower isn't necessary
3. The height of a standard chair
4. A full squat where the hamstrings touch the calves

Please answer all 10 parts to question

Answer 1

91. a) answer- Stiff hamstrings

Explanation- studies show that when hamstrings muscles are smaller( stiff or atrophied) compared to the quadriceps muscles , MRI showed more signs of knee meniscus and cartilage degeneration or swelling.

b) answer- Excessive pronation of the feet

Explanation-In knee vulgus, posture during standing may be associated with pes planus, everted calcaneus, an internally rotated femur, lower limb compensation for persistent femoral anteversion and internally rotated tibia or an anteriorly tipped pelvis.

c) answer-shortened hip flexors

Explanation-Excessive sitting causes hip flexors to tighten(ie, shorten), causes a change in the position of the pelvis.

d) answer-Recommend static stretches for his hamstrings

Explanation- stretching exercise increases muscle flexibility and range of motion
