What is EMS?

Electrical muscle stimulation (EMS) is the elicitation of muscle
contraction using electric impulses.

EMS has received an increasing amount of attention in the
last few years for many reasons: it can be utilized as a strength training
tool for healthy subjects and athletes; it could be used as a rehabilitation
and preventive tool for partially or totally immobilized patients; it could be utilized as a testing tool for evaluating the neural and/or muscular function in vivo; it could be used as a post-exercise recovery tool for athletes.
