This review updates the basic and clinical science regarding the use of TENS that has been published in the past 3 years (ie, 2005в€’2008). TENS has been used to treat a variety of painful conditions. Aches and pains are a part of life, but if they get in the way of daily living activities or compromise your quality of life, they need to be addressed.Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacologic treatment for pain relief. The number 5 entry on our list is the iReliev Pain Relief System Dual Channel TENS Massager by Excel Health, offering prescription-level pain relief without needing a prescription.

Clinical trials suggest that adequate dosing, particularly intensity, is critical to obtaining pain relief with TENS. This review also highlights data from recent randomized, placebo-controlled trials and current systematic reviews. Translational studies show mechanisms to prevent analgesic tolerance to repeated application of TENS.

Centrally, sites in the spinal cord and brainstem that utilize opioid, serotonin, and muscarinic receptors are activated by TENS. Prior reports show that TENS reduces pain through both peripheral and central mechanisms. Although a number of clinical studies show the effectiveness of TENS for pain, there is still much controversy over which conditions to treat with TENS and the adequate parameters to use. EMS (Electric Muscle Stimulator) causes relaxation, blood flow recovery and creates conditions for muscle growth, while TENS helps eliminate neck pain, arthritis, sciatica, and other forms of neuritis.Transcutaneous electrical nerve stimulation (TENS) is a commonly used nonpharmacologic and noninvasive treatment for pain. The new ergonomically designed device has the same parameters as its predecessor adjustable pulse rate.EMS-marked gadgets act on muscles directly while the impulse of TENS devices is set to affect the nerves.

Subsequent studies have investigated the role of serotoninergic, noradrenergic, muscarinic, and Оі-aminobutyric acid (GABA)-ergic systems on the analgesia produced by both low-frequency and high-frequency TENS.Fake Review and Counterfeit Analysis for TechCare Pro TENS Unit 24 Modes Best Portable. Specifically, we show that low-frequency TENS activates Ој-opioid receptors in the spinal cord and the brainstem, whereas high-frequency TENS activates Оґ-opioid receptors in the spinal cord and the brainstem. Prior literature from our laboratory shows that, regardless of intensity, different frequencies activate central mechanisms to produce analgesia. In general, higher-frequency stimulation is delivered at sensory intensity, and low-frequency stimulation is delivered at motor intensity. High intensity usually involves a motor contraction but is not painful. Sensory intensity is when the patient feels a strong but comfortable sensation without motor contraction.

We and others have tested the effectiveness of TENS on a variety of measures of both primary and secondary hyperalgesia. Secondary hyperalgesia occurs outside the site of injury, and it is thought to be mediated by changes in the central nervous system. Primary hyperalgesia is an increased pain sensitivity at the site of injury, which is thought to mirror changes in the peripheral nervous system. Hyperalgesia is an increased pain sensitivity to a peripherally applied stimulus.

However, as central mechanisms are activated by TENS, it is possible that application outside the site may also be effective. The site of electrode application of TENS is typically at the site of injury. Thus, it can be suggested that because inflammation has already completely developed, TENS inhibits primary hyperalgesia associated with inflammation in a time-dependent manner. Compression withdrawal threshold was decreased at 24 hours and 2 weeks following the induction of inflammation, but not when applied at 4 hours after the induction of inflammation. Showed that primary mechanical hyperalgesia induced by joint inflammation was reduced in response to both high- and low-frequency TENS. More recently, Vance et al.

Repeated daily high-frequency TENS for 12 days with electrodes positioned on the skin covering either ipsilateral or contralateral paraspinal muscles reduced the development of mechanical hyperalgesia in CCI rats. In a different pain model, Somers and Clemente investigated the sites of electrode placement that would best prevent the development of allodynia in a chronic constriction injury (CCI) to the rat sciatic nerve. Furthermore, when hyperalgesia developed bilaterally after a unilateral injury, application of either high- or low-frequency TENS to the inflamed or the contralateral side reduced the hyperalgesia bilaterally.

However, when a local anesthetic was applied to the inflamed knee joint during TENS application, there was a complete blockade of the analgesic effects of TENS. Specifically, blockade of cutaneous afferents with an anesthetic cream (eutectic mixture of lidocaine and prilocaine) during TENS application had no effect on the analgesia produced by both high- and low-frequency TENS. However, by differentially blocking primary afferents with local anesthetics, Radhakrishnan and Sluka showed the importance of deep tissue afferents in the analgesia produced by TENS. Thus, once hyperalgesia develops, application of TENS to either the ipsilateral or the contralateral hind limb is effective.It is generally thought that TENS produces analgesia by activation of cutaneous afferent fibers at the site of application.

The О±2A and О±2C AR subtypes mediate antinociception when activated by the endogenous ligand norepinephrine. Thus, it seems that peripheral О±2 ARs partially contribute to TENS-mediated analgesia. Furthermore, when an О±2 AR-selective antagonist (SK&F 86466) was administered intraarticularly, TENS-induced analgesia was reversed, but analgesia was not reversed when it was delivered intrathecally or intracerebroventricularly. TENS-induced analgesia, at both high and low frequencies of stimulation, was reduced in О±2A mutant mice compared with controls. Therefore, different waveforms can be used to improve comfort for the patients but not to increase analgesic efficacy.The effect of both high- and low-frequency TENS was tested in mutant mice lacking a functional О±2A-adrenergic receptor (AR) against their respective wild-type counterparts.

In another study, spinal serotonin concentrations were increased during and immediately after treatment with low-frequency, but not high-frequency, TENS. Interestingly, blockade of GABA A receptors with bicuculline prevented the reduction in hyperalgesia produced by both high- and low-frequency TENS. High-frequency, but not low-frequency, TENS applied to the inflamed knee joint increases extracellular GABA concentrations in the spinal cord dorsal horn in animals with and without joint inflammation. A recent study showed that the inhibitory neurotransmitter GABA, but not glycine, is also involved in this analgesia at the spinal level. Showed that blockade of Ој-opioid receptors at the site of application prevents the reduction in hyperalgesia produced by low-frequency TENS but not high-frequency TENS.Prior reports show the importance of the opioid pathways in pain inhibition at the spinal level. Peripheral opioid receptors also appear to play a role in the analgesia produced by low-frequency TENS.
