What, exactly, are tens machines?
A tens machine is a device which is used to reduce both acute as well chronic pain. The full form of TENS is Transcutaneous Electrical Nerve Stimulation. It is often addressed as pain machine or TNS machine. Whatever may it be, these devices are available in two forms: digital & analog. However, each machine features three to four major components that are responsible for the control of body pain. Let us have a brief look at some of these components.
RATE: This identifies the fact that what is the total number of time that the machine goes on and off on a per second basis.
WIDTH: As soon the machine is turned on, what is the duration of its stay? This is mainly calculated in milliseconds (millionths of one second).
AMPLITUDE: This is the power calculation component. What is the total amount wattage used in order to make the patient feel a certain amount of sensation? This question is sorted out through the use of this component.
No matter whether you have the analog or the digital device with you, but if these three mentioned components are present within your device, then there is no basic difference between digital and analog ones. However, there is also a situation where you may want some specific display types. This is something that is different much in digital devices if compared to the analog devices. Then there is also the size factor that may be a matter of concern.
These separate issues play important part in the selection. Most people tend to purchase a bright clear digital display in the tens machine. However, the craze for analog display can be seen mostly among the older patients who prefer bigger displaying devices with manual buttons.
