Research paper thumbnail of Effects of transcutaneous electrical nerve stimulation on H-reflex and spinal spasticity

Scandinavian Journal of Rehabilitation Medicine

Considering the reflex hyperexcitability commonly displayed in spinal cord-injured subjects, it was hypothesized that repetitive low threshold afferent stimulation would have an inhibitory effect on the triceps surae H-reflexes which could also be reflected by a decrease in plantarflexor spasticity. Clonus, Achilles tendon reflex and modified Ashworth evaluations were performed on 14 spinal cord-injured subjects prior to and after 30 minutes' application of TENS. Non-parametric statistical analyses (n = 14; alpha = 0.05) failed to reveal significant effects of TENS on H-reflex amplitude. However, there was a significant decrease in scores for the Achilles tendon reflex and the modified Ashworth test. The clonus score decreased in most subjects post-TENS, although not in a statistically significant manne...

Eleven subjects were tested in five experimental sessions, the purpose of which was to compare the effects of 30 minutes of TENS delivered at either 50 or 99Hz (250 microseconds pulses) on a mixed (common peroneal nerve or CPN) versus a sensory (sural) nerve. The soleus H-reflex was elicited according to the classic protocol of Hugon (1973). Control values (Hctrl) were measured for 5 minutes prior to and for 10 minutes after the TENS was administered at twice the sensory threshold. No statistically significant session (treatment) effects (two-way ANOVAs for repeated measures; alpha = 0.05) resulted from the stimulation of the CPN or the sural nerve at 50 or 99Hz. However, although no specific trends were shown across all subjects, there was a definite tendency towards inhibition (> or = 10% Hctrl) of the H-reflex in 63% of the subjects after 30 minutes of TENS at 99Hz over the CPN, and in 50% of the subjects when TENS was applied over the sural nerve at 99Hz. The inherent variability of the H-reflex amplitude in normal subjects as well as the use of different stimulation paradigms and TENS parameters could explain the controversial findings present in the literature.

Research paper thumbnail of Comparison of the EMG power spectrum of the human soleus and gastrocnemius muscles

European journal of …, Jan 1, 1994

The purpose of this study was to compare the behaviour of electromyographic (EMG) power spectrum ... more The purpose of this study was to compare the behaviour of electromyographic (EMG) power spectrum statistics, mean power frequency (MPF) and median frequency (MF), across increasing force levels of the soleus (SO), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL) muscles. Surface EMG signals of these three muscles were recorded in 12 men and 10 women during both (1) ramp (single ongoing contractions with the force increasing linearly from 0 to 100% of the maximum voluntary contraction (MVC); and (2) step (steady force levels: 10, 20, 30, 40, 60 and 80% MVC) static (isometric) plantar flexions. Power spectral analysis of these signals was performed on single 256-ms windows at all of the above-mentioned force levels, for both types of contraction. The MF and MPF were calculated from each of the obtained spectra. A less pronounced increase in the MF or MPF was expected for the SO because of its higher type I fibre content. The main results are as follows: (1) similar behaviours were found in the value of MPF and MF across increasing force for the SO and GL muscles, while the GM gave rise to a different behaviour; (2) no difference was found between ramp and step contractions in the behaviour of either MF or MPF across force levels; and (3) different behaviours were observed between the MF and MPF across increasing force levels, for both ramp and step contractions. Our initial expectations were thus not confirmed. It is concluded that the present results support the hypothesis that the EMG power spectrum may be more sensitive to the diameter of the fibres than to the fibre type proportion of the triceps surae muscles. Furthermore, the sensitivity of the power spectrum statistics of a given muscle to the low-pass filter effect of its skin layer was also emphasized.
