TENS Science

Post by admin » Sat Mar 14, 2020 7:24 am

The science behind TENS and pain is pretty well established (probably).

Not too much research on TENS helping spasticity. As usual, zero for our disease.

Try these:

The Effects of Exercise with TENS on Spasticity, Balance, and Gait in Patients with Chronic Stroke: A Randomized Controlled Trial

You can download the PDF file here

This one used a frequency of 100 Hz and a pulse width 200 μs


Given the findings of this study, we can logically assume that exercise therapy with TENS improves spasticity, balance, and gait in chronic stroke patients and could be actively used in clinic settings as an adjunct to conventional physical therapy.

Effect of Transcutaneous Electrical Nerve Stimulation on Spasticity in Adults With Stroke: A Systematic Review and Meta-analysis

There is strong evidence that TENS as an adjunct is effective in reducing lower limb spasticity when applied for more than 30 minutes over nerve or muscle belly in chronic stroke survivors

The effects of exercise with TENS on spasticity, balance, and gait in patients with chronic stroke: a randomized controlled trial.

A combination of therapeutic exercise and TENS may reduce spasticity and improve balance, gait, and functional activity in chronic stroke patients.
And here is a study on applying TENS to the
sural nerve
, right where I apply the electrodes to stimulate my calf muscles.


Effects of transcutaneous electrical nerve stimulation (TENS) on spasticity in patients with hemiplegia.

The results of the study support the hypothesis that TENS applied to the sural nerve may induce short-term post-stimulation inhibitory effects on the abnormally enhanced stretch reflex activity in spasticity of cerebral origin.

Relief of hemiparetic spasticity by TENS is associated with improvement in reflex and voluntary motor functions.

Our results thus indicated that repeated applications of TENS can reduce clinical spasticity and improve control of reflex and motor functions in hemiparetic subjects. Furthermore, the underlying mechanisms may be due partly to an enhancement in presynaptic inhibition of the spastic plantarflexor, and partly to a possible "disinhibition" of descending voluntary commands to the paretic dorsiflexor motoneurons.

A single trial of transcutaneous electrical nerve stimulation (TENS) improves spasticity and balance in patients with chronic stroke.

The TENS group showed a significantly greater reduction in spasticity of the gastrocnemius, compared to the placebo-TENS group (p < 0.05). TENS resulted in greater balance ability improvements, especially during the eyes closed condition (p < 0.05). However, these effects returned to baseline values within one day. This study shows that TENS provides an immediately effective means of reducing spasticity and of improving balance in chronic stroke patients
Final one (for now).

Transcutaneous electrical nerve stimulation improves walking capacity and reduces spasticity in stroke survivors: a systematic review and meta-analysis.
