What are asymmetrical wave forms used for Small mm
What size should the electrode be Largest electrode that provides desired response w/o causing overflow to other mm
which electrode is more active in the symmetrical wave form Both are active
which electrode is more active in the asymmetrical wave form the negative
Where should the negative electrodes be placed for either wave form over the motor point
What is a motor point Place in the mm where electrical stimulation will produce the greatest contraction w/the least amount of electricity, generally over the middle of the mm belly
The greater the distance between electrodes determines a deeper current flow
