Abstract
A method for quantitatively assessing muscle contraction of a facial muscle in a person and determining the ability of a treatment material to reduce contraction of the facial muscle is disclosed. The method can include applying an external electrical stimulus to facial skin sufficient to contract a facial muscle, measuring the contractile activity of the contracted facial muscle by measuring the compound motor action potential (CMAP) of the contracted facial muscle to obtain a first average measurement of contractile activity of the contracted facial muscle, administering the treatment material by topically applying the treatment material to the facial skin, and repeating steps (a) and (b) to obtain a second average measurement of contractile activity of the contracted facial muscle.
