Electrical Muscle Stimulation (EMS) is the elicitation of muscle contraction using a electric impulse device. EMS has received an increasing amount of attention in the last few years for many reasons:

• It can be utilised as a strength training tool for healthy subjects and athletes.

• It can be used as a rehabilitation and preventive tool for partially or totally immobilized patients. 

• It can be utilized as a testing tool for evaluating the neural and/or muscular function in vivo.

• It can be used as a post-exercise recovery tool for athletes.
