We studied effects of test H-reflex size on reciprocal Ia inhibition in for
earm muscles. In both healthy control subjects and hemiplegic patients, the
amount of Ia inhibition decreased as the test H-reflex size increased. It
is possible that forearm reciprocal Ia inhibition in hemiplegics reported p
reviously might be underestimated due to larger test H-reflexes used in the
hemiplegics than in the controls. (C) 1999 Elsevier Science Ireland Ltd. A
