Abstract		Many individuals who have had poliomielitis many decades ago, are now complaining of several new problems, predominantly progressive weakening, low muscle endurance and unexplained fatigue in previously affected and unaffected muscles. The aim of the study was to compare the strength and endurance of m. quadriceps femoris in persons after paralitic poliomielitis and healthy subjects. We also compared strength and endurance of same muscles in subjects with and without new symptoms after paralitic poliomyelitis. 30 subjects after paralitic poliomyelitis were included in study Regarding complaining of new problems, they were divided in two groups ("with new problems" and "without new problems"). The control group of similar number, age, gender and lifestyle was composed of healthy subjects. The standard manual muscle test and isometric dynamometer were used for assesment of the maximal strength of m. quadriceps femoris. The endurance was defined as time in which subject was able to mantain force in m. quadriceps femoris, equivalent to 40 - 45% of maximal force, as long as possible on isometric diuamometer. Our study revealed no difference in strength during maximal voluntary contraction of m. guadriceps femoris of more affected leg between both groups after poliomyelitis (p = .989) The difference in endurance of m. quadriceps femoris, between both groups after poliomyelitis was not found by assesment with isometric dinamometer. All subjects after poliomyelitis revealed significantly weaker m. quadriceps femoris of less affected leg, compared to controls (p = .001). No difference in endurance af m. quadriceps femoris in less affected leg was found in both groups after poliomyelitis (p = .169). All subjects after poliomyelitis had significant lower endurance of m. quadriceps femoris in their less affected leg, compared to push-off leg in controls (p = .001).

Summary		Glede na literaturo, nove težave desetletja po akutni bolezni navaja več kot polovica oseb po prebolelem paralitičnem poliomielitisu. Preveriti smo želeli razliko v moči in vzdržljivosti štiriglave stegenske mišice med skupino oseb po prebolelem poliomielitisu in kontrolno skupino zdravih prostovoljcev. Preveriti smo želeli tudi razliko v moči in vzdržljivosti štiriglave stegenske mišice med skupino oseb po poliomielitisu z novimi simptomi in skupino brez njih. Dodatno smo želeli preveriti ali se moč štiriglave stegenske mišice ocenjene z ročnim mišičnim testom z oceno "normalno" (5/5), pri osebah po prebolelem poliomielitisu ob meritvi z izometričnim dinamometrom razlikuje od moči te mišice pri osebah v kontrolni skupini. V študiji je sodelovalo 30 oseb po prebolelem poliomielitisu, ki so imeli moč štiriglave stegenske mišice vsaj enega uda ocenjeno z oceno tri (3/5) ali več z RMT ter 15 zdravih prostovoljcev. V študijski skupini je 15 oseb navajalo nove težave po poliomielitisu. Za meritev moči in utrujanja mišice smo uporabili izometrični dinamometer "Biodex". Vzdržljivost štiriglave stegenske mišice smo ocenili s trajanjem hotene zadrževane kontrakcije pri fleksiji 60° kolenskem sklepu, v območju med 40 in 45% največje hotene kontrakcije. Povprečna vrednost navora v kolenskem sklepu med največjo hoteno izometrično kontrakcijo (NHK) mišic iztegovalk kolena bol prizadete noge oseb z novimi simptomi se ni značilno razlikovala (p = 0,989) od povprečne vrednosti navora istih mišic bolj prizadete noge oseb brez novih simptomov po poliomielitisu. Povprečna vrednost navora med največjo hoteno izometrično kontrakcijo iztegovalk kolena manj prizadete noge vseh oseb po prebolelem poliomielitisu se je statistično značilno (p < 0,001) razlikovala od povprečne vrednosti navorov izmerjenih pri osebah v kontrolni skupini.
