Hip CPG - Hamstring Strain

Question 1

What is a risk factor for future reinjury of hamstring?

Answer 1

B

history of hamstring strain

Question 2

How should clinicians should assess hamstring length?

How is it related to severity of injury?

Answer 2

A

measuring the knee extension deficit with the hip flexed to 90

A greater knee extension deficit may indicate a more severe injury

Question 3

What should be used before and after interventions,
intended to alleviate the impairments of body function and structure, activity limitations, and participation restrictions in those diagnosed with an acute HSI?

Answer 3

B

Functional Assessment Scale for Acute Hamstring Injuries (FASH)

Question 4

What exercise should be used as part of a hamstring injury prevention program?

Answer 4

A

Nordic hamstring curls

Question 5

What is a critical intervention that should occur prior to RTS and may be a risk factor for reinjury if not included?

Answer 5

B

eccentric hamstring training

Question 6

What is the most commonly injured hamstring muscle?

Answer 6

Biceps femoris

Question 7

What relationship has been found between hamstring flexibility and hamstring injury?

Answer 7

None

Question 8

What interventions receive and A level recommendation for hamstring injury prevention?

Answer 8

1. Nordic Hamstring Exercise

Question 9

What are the highest recommended interventions after a hamstring strain?

Answer 9

B

1. Eccentric training
   -added to multimodal program to improve RTP time
2. Progressive Agility and Trunk Stabilization
   -added to multimodal program to reduce reinjury rate

Question 10

What 4 things should clinicians use to estimate time to RTP?

Answer 10

B

1. Hamstring strength
2. Pain level at time of injury
3. Number of days from injury to pain-free walking
4. Area of tenderness measured at initial eval

Question 11

What 4 things should be used to make a diagnosis of a hamstring strain injury?

Answer 11

1. Sudden onset of posterior thigh pain during activity
2. pain reproduced when hamstring is stretched or activated
3. muscle tenderness with palpation
4. loss of function

Question 12

How should knee flexion strength be examined?

Answer 12

A

Handheld or isokinetic dynamometer

Question 13

How should hamstring length be measured?

Answer 13

A

Measure the knee extension deficit with the hip flexed to 90 degrees using an inclinometer

Question 14

Palpation of what can assist in predicting return to play time?

Answer 14

1. Length of muscle tenderness
2. Proximity to ischial tuberosity

Question 15

Recommendation for neural tissue mobilization?

Answer 15

F

Clinicians may use neural tissue mobilization after injury to reduce adhesions to surrounding soft tissue

Question 16

A higher percentage of what type of muscle fiber likely makes hamstring muscles more susceptible to injury?

Answer 16

Type II (fast twitch)

Question 17

What posture may increase risk of hamstring injury?

Answer 17

Anterior Tilt

Question 18

What 2 muscle architecture characteristics may contribute to hamstring injury strain?

Answer 18

1.Higher Pennation Angle

2. Shorter Fascicle Length

Question 19

A hamstring injury within what amount of time places patients at an even greater risk of reinjury?

Answer 19

within 8 weeks

Question 20

How does the injury to muscles compare in Grade I, II, and III strains?

Answer 20

Grade I - microtearing of a few muscle fibers

Grade II - moderate tearing of a muscle fibers

Grade III - complete tear of the muscle
