The effect of exogenous TSH and Achilles tendon reflex time in man.
The effect of exogenous thyrotropin (TSH) -- 3 X 10 IU daily -- on Achilles tendon reflex time (ART) was investigated in the group of 38 in-patients, treated for thyroid cancer. A significant shortening of ART was recorded in a subgroup of hypothyroid persons after the 2nd and 3rd dose of TSH. Moreover, a significant correlation was proved between initial values of ART and their changes after the 2nd and 3rd TSH injection in this group. No significant interrelationship was observed between changes of thyroid function and ART after TSH administration. In interpretation of this finding the possibility of direct effect of TSH on muscle metabolism in hypothyroid man should be considered.
