Varied scientific evidence advocates that there are exterior and central nervous system mechanisms underlying the painkilling action of TENS machines. Studies have also demonstrated that tolerance to the repeated usage of TENS machines can be prevented by applying treatment strategies, both pharmacological and non-pharmacologic. Pain study experiments and clinical trials are starting to define the parameters of stimulation necessary to obtain the best pain relief. It’s probable that stimulation concentration is a main factor for the efficacy of TENS.
TENS machines against musculo-skeletal pain
Analysis was able to show the positive treatment effects of electrical stimulation for relief of chronic Musculo-skeletal pain. Furthermore, random controlled trials constantly validate the effectiveness of TENS machines in the treatment of acute, emergent, and post-operative pain conditions.
The effectiveness of TENS machines
To conclude, random, placebo-controlled clinical trials have shown that TENS has proved effective for several chronic pain conditions that are connected with emergent and post-operative conditions. TENS machines have proved consistently more effective than placebo actions for pain intensity, anxiety, and heart rate in these studies. Usage of high-intensity stimulation and high-frequency TENS has been seen to be the most effective usage of TENS machines, principally in the short term.
