This unit of stimulator is attached to the skin by using the electrodes which are usually the gel pads in nature. These electrodes are two or more in number. A battery is also connected to these electrodes which transmogrify the electric pulse, width and its intensity. Generally the electric pulse is applied at a high frequency which is greater than 50 Hz which may be responsible for motor contraction. The use of TENS unit is also clinically proven.

EMS is the stimulation of muscle by using electrical devices which also help in the reduction of muscular pain. EMS is applied to obtain better results. A low voltage or low intensity electric impulse is applied to the muscle by using different electrodes which are connected to the skin. These simulators help in two ways;

• Relieving the pain
• Contracting the muscle and strengthen it by using electric shocks without the involvement of nerves which may cause fatigue or pain.

TENS unit stimulates the body by using different electrodes which apply different pulses of electricity with the low voltage. These mechanisms may cause pain and work in three different steps which are discussed below:

They help increase the blood circulation.
TENS unit is also responsible for the increase in production of endorphins which are the naturally synthesized painkillers in our body.
It is also responsible for the transmission of pain signals to the brains through nerves.
EMS on the other hand stimulates the muscles and helps in minimizing the pain in muscular region. EMS also works in the same way as TENS as it also provides low voltage which contracts the muscle. Contraction helps in reduction of the pain and relaxes the muscles. It also serves the following measures:

• Gives comfort to the muscle.
• Reduces inflammation in muscular region.
• Prevents muscular entropy.
• Strengthen the muscle and stimulate its growth.
• Helps in faster healing process.

TENS unit is used for the muscles, joint pains or to relieve nerve pain. It is for the chronic disorders like inflammation in any part of the body, joint pain, back pain, foot pain, inflammatory arthritis post-operation pains or contractions after birth. There are also specialized TENS machines which help in relieving migraine pain.

EMS is used for the stimulation of muscle and its blood circulation. It is on the other hand used to strengthen the muscle and relaxes in case of muscles spasm, poor blood circulation or muscle entropy or a part of rehabilitation after some injury. Athletes sometimes also used EMS to recover quickly. Electric shocks are applied to relax the muscle and enable a muscle to rebuild its strength.

MAJOR DIFFERENCES BETWEEN THESE TWO STIMULATORS

TENS unit machines help in the stimulation of nerve exclusively for the relieving of pain whereas EMS unit are used to strengthening and rehabilitating the muscles. Mostly EMS is recommended highly than TENS.

Different online brands and even shops are offering different devices for the stimulation of nerves and muscles. These electric devices are usually high in rates but also very advanced in their forms and functions. But with the advancement of every stage in their functions, these brands offer their best products for their customers.

There is a brand named ZARIFA USA which offers different TENS and EMS devices which are highly advanced in the products. They take care of their customer satisfaction and keep in view that their customers are getting complete satisfaction. There are the devices provided by this brand which is given below:

• Massage back belt

There are different belts that relieve the backaches and help in relieving the pain after some injury or infection.

• Massage Kit

Also available for massaging different areas of the body and help in relaxing them.

• Massage Shoes

Also offered by different companies or brands to relax the feet by their massaging surface or different structures which are specifies for the relaxing of feet and legs.

• Massage Socks

Kits are usually available to the doctors which are expertise in massaging different parts of the body. These massaging kits help in strengthening the muscles and make nervous system more operational and effective.

There are also different massagers are available and different heat pads are also used for the reduction of pain in back, neck, legs or feet. Different exercise is also available. Electric pulses generated by these products or accessories are in the form of different breaks which help in minimizing and contracting different parts of the body. These body parts contract in such a way that all the pain vanishes and it also reduces inflammation. Different people are working on it and making it more useful for the people who are facing problem of body pain. These are also recommended to the mothers who recently give birth to the child. They should wear belts so that it cannot let the abdominal skin falls. It also reduces their backaches which is the major problem after giving birth to a baby. These TENS and EMS are really useful and become an important factor of the society as it gives relief to the pains. Without these pains, a person can live a healthy life with all the desire he wishes for. One must go for these products if he is facing any kind of pain.
