Electronic Muscle Stimulators, or EMS, are sometimes referred to as neuromuscular electrical stimulation and they are used to stimulate muscle contractions via electrical impulses. The impulse replaces the action potential, which is the signal sent from the brain to cause muscle contraction. They can be used to improve muscle fibres for athletes as well as in the medical field for injured muscle rehabilitation and to combat muscular dystrophy.
1st Choice EMS
This is a budget-range EMS that costs approximately $99. For this price you get 4 pads, which allow you tone two areas at the same time. It is easy to use, has value for money, large dials and an adjustable pulse rate. The pulse rate can be adjusted from one to 80hz to suit the needs of the individual.
Body Clock Duo
This EMS costs in the region of $200. It works as both a pain reliever and a muscle stimulator, it also has up to eight pads so you can work multiple areas at the same time. The main benefits are pain relief, the multiple pads, two contraction timers and three different modes. The pulse rate is stronger than the 1st Choice, ranging from one to 150Hz.
Profile EMS
This again is a more expensive unit, priced at around $200, and is completely digital. This unit has seven programmable modes to stimulate both single muscles or large muscle groups. This unit has the ability to reach 120Hz and the key benefits are that it has safety features to stop muscle damage, it is easy to use, and has a automatic shut down to save battery life. It also has a memory facility to repeat particular sessions easily.
TMT-540
One of the more expensive systems is the Tone-a-matic 540, priced in the region of $340. It has four settings which work with EMS as well as TENS for stimulation and pain relief. TENS is defined as transcutaneous electrical nerve stimulation, which helps to relieve pain in the muscles. This product is easy to use, and has a stimulation frequency up to 200Hz, the highest of all the units. It also comes with eight large carbon fibre pads and 4 small pads for improved locality of stimulation.
