A study conducted by the University of Calgary shows that the botulinum toxin, commonly known as Botox, which is widely used in wrinkle reducing procedures can have serious adverse effects. This study, led by Walter Herzog, professor of kinesiology at the university, is currently available online and will soon be published in the upcoming hard-copy edition of the Journal of Biomechanics.

Highlights of the study
a. Researchers used Botox injections in a study of how muscle weakness contributes to joint degeneration.
b. Botox was used as an agent to temporarily paralyze muscles.
c. The injection doses used in the study are similar to those used in human injection protocols for the soleus muscle, both for spastic cerebral palsy in children and hemi-plegic adults secondary to stroke.
d. It was noticed that the toxin can easily pass from the targeted muscle into surrounding ones.
e. This weakens all the muscles in the area.
f. It also shows that the administration of this toxin is not easy to control.
