Injury Management Rehabilitation & Return to Play Flashcards
What are the short term goals of injury rehab?
- control pain and minimize swelling
- maintain / improve flexibility
- enhance core stability
- restore / increase strength & endurance
- re-establish neuromuscular control / proprioception / balance
- maintain cardiorespiratory fitness
- functional progressions
what is the long term goal of injury rehabilitation
return to practice / competition as quickly and safely as possible
When should you begin rehabilitation?
a) 12 hours post injury to allow for swelling to decrease
b) 1 week post injury to allow for fibroblastic repair
c) 1 week post injury to allow for inflammation to subside
d) immediately
e) B & C
D - immediately
What are some factors to consider when developing a return-to-play plan? (7 points)
- MOI
- age of individual
- major anatomical structures involved
- injury severity
- stages of tissue healing
- type of sport or activity
- chronicity of the injury
Resting heart rate increases approximately ____ beat for each day of immobilization
1/2
When should you start exercising in a pain-free ROM post injury?
by day 3 or 4
When does post-surgical exercise phase begin?
a) immediately
b) 12 hours post surgery
c) 24 hours post surgery
d) 48 hours post surgery
e) none of the above
B - post-surgical exercise phase begins 24 hours post-surgery
What does POLICE stand for?
Protect Optimal Loading Ice Compression Elevation
define load
external force acting on the body causing internal reactions within the tissues
define stiffness
- ability of a tissue to resist a load
- greater stiffness = greater magnitude load can resist
define stress
internal resistance to a load
strain
internal change in tissue (length) resulting in deformation
draw out the stress-strain relationship
force that results in tissue crush - two forces applied towards one another is called
compression
force that pulls and stretches tissue
tension
force that moves across the parallel organization of tissue
shear
- two force pairs act at opposite ends of a structure
- 3 forces cause bending (3 points)
- already bowed structures encounter axial loading
bending
- loads caused by twisting in opposite directions from opposite ends. Shear stress encountered will be perpendicular and parallel to the loads
torsion
true or false; bone bending, but not breaking can still cause a pathological response
true
healing time of muscle strains
6-8 weeks
1st degree mm strain
some fibers stretched or torn, full ROM but painful
2nd degree muscle strain
multiple fibers torn. Active contraction is painful. Divot palpable. Some swelling and discolouration. Decreased ROM
3rd degree mm strain
complete rupture of mm, at the MT junction or off of the bone. Significant impairment. Great deal of pain initially but diminishes due to nerve damage
true or false; extreme mm fatigue can lead to cramps
true
true or false; muscle guarding and muscle spasms are synonymous
false;
mm guarding is splinting to minimize pain
mm spasm is increased tone d/t upper MN lesion in brain
two types of mm spasms
- ) clonic
2. ) tonic
true or false; crepitus could be associated with tendinitis
true
how would you treat tendinosis?
a) immediate rehab
b) it is chronic, so impossible to treat
c) stretching and strengthening
d) none of the above
stretching and strengthening
what would you expect with acute and chronic tenosynovitis?
acute - rapid onset, crepitus, diffuse swelling
chronic - thickening of tendon with pain and crepitus
true or false; contusions can lead to overproduction of calcium deposits and lead to myositis ossificans
true
what are the components of a synovial joint?
- hyaline and/or articular cartilage
- fibrous connective tissue capsule
- ligaments
- capsule with synovial membrane
- joint cavity with synovial fluid
- blood and nerve supply
- muscles
- menisci (fibrocartilage)
grade 1 ligamentous sprain
- minor fiber damage & minimal instability
- mild to moderate pain
- minimal loss of function and swelling
grade 2 ligamentous sprain
- tearing of fibers with moderate joint instability
- moderate to severe pain
- swelling & moderate loss of function
grade 3 ligamentous sprain
- complete tear and may sublux
- extreme pain initially
- inevitable loss of function
- severe instability and swelling
define subluxation
- partial dislocation
- spontaneous joint relocation
true or false; in the case of a dislocation, attempt to reduce
false; do not reduce
define dislocation
- complete disarticulation of a joint
- stabilizing structures disrupted
separation
separation of the fibrous joint d/t stretching/ tearing of the supporting tissues
Wolff’s Law of bone
- every change in form and function or in its function alone is followed by changes in architectural design
types of bone fractures
- greenstick
- comminuted
- linear
- transverse
- oblique
- spiral
- avulsion
- impacted
- depressed
