musculoskeletal injuries-unit 4

Question 1

what are some known association/movement risks?

Answer 1

ACL injuries in cutting and landing activites (females 4-9x more likely), low back injuries in lifting, tendinitis in repetitive movements, and shin splints in running.

Question 2

what are some ingredients for injury?

Answer 2

bad technique (due to fatigue, inflexibility, anatomy, weakness), excessive overload, chronic overuse (too much volume or too little recovery), and ignoring warning signs (the no pain no gain idea can be dangerous in athletes.)

Question 3

what is an acute injury?

Answer 3

usually associated with macro trauma , one second everything is good and the next it is not. T

Question 4

what is a strain?

Answer 4

tears, ruptures, avulsions involving muscle or bone. tears occur within the muscle belly, at junction, or the tendons attachment to bone. TENDONS and MUSCLES

Question 5

what are the degrees of muscle tears?

Answer 5

1st- partial tear, strong still but painful with activity. 2nd- partial tear, weak now and painful with activity. 3rd- complete tear very weak but no pain.

Question 6

what is a contusion/hematoma?

Answer 6

bruise

Question 7

what is a sprain?

Answer 7

a ligamentous tear, rupture, avulsion, etc. can be from blunt force (falling, dropping something), IV disk herniation, skeletal fracture, or dislocations.

Question 8

what is dislocation?

Answer 8

complete displacement of joint surfaces

Question 9

what is sublaxation?

Answer 9

partial displacement of the joint surfaces

Question 10

what are some examples of chronic overuse injuries?

Answer 10

tendon- tendonopathies (tennis elbow, jumpers knee) DONT USE TENDINITIS. can also have skeletal microdamage (micro fractures “shin splints”)

Question 11

what are some common ingredients to chronic injuries?

Answer 11

poor program design (too much volume, too little rest), suboptimal training surfaces (too hard or uneven), bad mechanics or technique, insufficient motor control, decreased flexibility, skeletal malalignment

Question 12

what are some common joints injured with strength training?

Answer 12

knee, shoulder, low back, wrist, elbow, neck

Question 13

what are some common joints injured with endurance training?

Answer 13

knee, foot, ankle, lower leg, hip

Question 14

how do we manage acute injuries?

Answer 14

know first aid, get person to correct medical professional, and RICE if soft tissue injury

Question 15

how do we manage chronic overuse injuries?

Answer 15

avoid the movement for a while (BEST), anti inflammatory meds- this also only masks the symptoms and does not actually fix the underlying cause. this can be bad becuase if they dont feel the pain anymore they think it is fixed and can actually make it worse

Question 16

what are some identifying risks of injury?

Answer 16

personal or medical history, known association with certain activities, injury prone people?, rehab for prevention.
