Nedsat styrke i quadriceps er en hyppig følge af skade på forreste korsbånd / ACL samt ACL-rekonstruktion / ACLR. Flere studier har vist at quadricepsstyrken før operationen indikerer hvordan styrken omkring knæet og funktionsevnen efter operationen vil være (1,2). Mange patienter har efter ACLR vedvarende nedsat styrke i quadriceps, hvllket bl.a. medfører ændret gangfunktion, asymmetri samt nedsat præstationsevne.(3,45,6,7,8). Det er alt afgørende at få etableret quadricepsstyrken inden og efter operationen hurtigst mulig og til det er en af de vægtigste værktøjer, neuromuskulær elektrisk stimulering / NMES. NMES har i flere studier vist fantastiske egenskaber til ACL-rehabilitering.
Effekter af NMES på ACL rehabilitering
1. Reducerer smerte (9)
2. Reducerer hævelse (9)
3. Reducerer ekstensionsdeficit (9)
4. Reducerer graden af atrofi (9,10,12)
5. Reducerer tab af muskelstyrke (10,12)
6. Opbygger muskelstyrke (10,11,12)
7. Øger funktionsevnen (11)
8. Hurtigere tilbage på arbejde (11)
