our results revealed : ( 1 ) change in length at different passive tensions is in the muscle belly , not in the tendon , ( 2 ) in hemiplegic patients no statistical difference in elongational characteristics of affected gastrocnemius muscle bellies with clinically demonstrated ankle pf contractures and of the contralateral nonaffected muscle bellies , ( 3 ) spastic and flaccid gastrocnemius muscle bellies are not statistically different in respect to passive elongations , ( 4 ) gastrocnemius muscle bellies of both affected and nonaffected legs of hemiplegic patients were statistically different from the muscle bellies of healthy persons in regard to maximal rom and maxinum muscle belly length changes , ( 5 ) there was approximately .5 mm change in the belly length for each degree of ankle rom , ( 6 ) age is not a factor influencing passive elongation of muscle belly , ( 7 ) average muscle belly lengths were consistently shorter in hemiplegic muscles while their tendon lengths did not change .
