Hip & thigh injuries Flashcards

1
Q

muscle strains - MOI

A
  • explosive concentric contraction
  • quick start/stop, change of direction
  • eccentric contraction - lengthening; some muscles do two different actions simultaneously at two different joints
  • overstretching

contributing factors: fatigue, pelvic asymmetry, strength imbalance, leg length discrepancy, muscle tightness

Q

muscle strains can occur acutely or chronically, why?

A

-can become a chronic issue if there is no rest, during the repair process, scar tissue forms (creates a weak point in muscle)

Q

initial management for muscle strain

A
  • POLICE - tensor wrap/compression shorts, activity modification but early return to walk (want to engage muscle a bit; avoid intense activities)

Q

what types of therapy can be used to manage muscle strains after the initial treatment
