Contracture was measured as loss of elbow joint range of motion and spasticity as the presence of abnormal reflex activity. <\/jats:p><jats:p> Results: Associated reactions were present in at least one testing condition in seven subjects. During contractions of the contralateral biceps brachii, the median amount of elbow flexor torque produced was 0.39 (interquartile range, IQR 2.5) Nm while during contractions of the contralateral quadriceps muscle it was 0.19 (IQR 1.6) Nm. Associated reactions were not associated with contracture (p = 0.39) which was present in over half of the subjects. The incidence of associated reactions was about the same as that of spasticity, but the two were not related (p = 0.61). <\/jats:p><jats:p> Conclusions: Even though associated reactions were present in 29% of the subjects during moderate contraction of the contralateral muscles, they were not large, nor were they associated with contracture or spasticity, suggesting that this phenomenon is not usually a major problem for everyday function after stroke. <\/jats:p>","DOI":"10.1191\/026921501676635731","type":"journal-article","created":{"date-parts":[[2003,5,13]],"date-time":"2003-05-13T05:30:08Z","timestamp":1052803808000},"page":"186-194","source":"Crossref","is-referenced-by-count":24,"title":["Do associated reactions in the upper limb after stroke contribute to contracture formation?"],"prefix":"10.1177","volume":"15","author":[{"given":"Louise","family":"Ada","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas","family":"O'Dwyer","sequence":"additional","affiliation":[{"name":"School of Physiotherapy, The University of Sydney, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2001,4,1]]},"reference":[{"key":"atypb1","first-page":"404","volume-title":"Disturbances of nervous function.
