Effects of stimulation parameters on modification of spinal spasticity.
TLDR
No universal optimum combination of stimulation parameters could be established but stimuli of 100 Hz and 100 μs pulse width were more effective than other combinations.Abstract:
Various electrical stimuli with frequencies from 10 Hz to 1000 Hz and pulse widths from 10 μs to 1000 μs were applied to seven spinal-cord injured patients with spasticity of the knee muscle. Spasticity was assessed with the pendulum test and EMG activity in the quadriceps and hamstrings. No universal optimum combination of stimulation parameters could be established but stimuli of 100 Hz and 100 μs pulse width were more effective than other combinations. Subjective remarks of patients regarding the effects over 24 h did not always correlate with measured data obtained within one hour after stimulation.read more

Long-lasting reductions of spasticity induced by skin electrical stimulation
TL;DR: In seven of the nine subjects, stimulation of skin over spastic muscle reduced peak torque responses in both flexors and extensors for at least 30 min, and in these seven subjects there were significant increases in mean threshold angle for the onset of reflex torque so that a greater angular rotation was required to initiate the stretch reflex response.

TL;DR: A way to suppress spasticity at a metameric site and to increase walking speed effectively by applying surface ES on the muscle–tendon junction of spastic gastrocnemius muscles is demonstrated.

Comparison of transcutaneous electrical nerve stimulation (TENS) and functional electrical stimulation (FES) for spasticity in spinal cord injury - A pilot randomized cross-over trial
TL;DR: The findings of this preliminary study suggest that both TENS and FES have the potential to be used as therapeutic adjuncts to relieve spasticity in the clinic and may have better effects on patients presenting with spastic reflexes.

Therapeutic electrical stimulation following selective posterior rhizotomy in children with spastic diplegic cerebral palsy: a randomized clinical trial.
TL;DR: It was concluded that TES may be beneficial in children with spastic CP who have undergone a selective posterior lumbosacral rhizotomy procedure more than 1 year previously.

A video-based version of the pendulum test: technique and normal response.
Barry C. Stillman,Joan McMeeken +1 more
TL;DR: It is concluded that the video-based pendulum test is a simple reliable source of measures with considerable potential for the clinical and physiological investigation of neurological and nonneurological features of normal and abnormal passive joint motion, and as a standard against which the effects of therapeutic intervention, such as medication, may be evaluated.

Electroacupuncture analgesia could be mediated by at least two pain-relieving mechanisms; endorphin and non-endorphin systems.
TL;DR: Electroacupuncture analgesia induced by low frequency stimulation may be mediated by endorphins while high frequency stimulation is not endorphinergic but may be partly due to serotonin.

Pendulum testing of spasticity

TL;DR: The described instrumentation and evaluation of the pendulum test provide an effectiveSpasticity testing in the clinical environment and the correlation coefficients are calculated to determine the parameters relevant for the estimation of spasticity.

Post-tetanic potentiation at the neuromuscular junction of the frog.
TL;DR: Post‐tetanic potentiation was studied at the neuromuscular junction of the frog and the magnitude and time course of PTP was dependent on the number of stimuli in the tetanus, rather than on the frequency or duration of the Tetanus.

A critical review of the evidence for a pain-spasm-pain cycle in spinal disorders.
TL;DR: The evidence reviewed provides general support for the existence of a pain-spasm-pain cycle in patients with back pain, but further work is required to determine the nature of spasm and to evaluate methods for its detection, particularly in acute back pain syndromes.
