Gulcin Demirel, Nur Kesiktas: Istanbul Physical Medicine and Rehab., Istanbul, Turkey
Purpose: Evaluation of compex effect at spasticity in Spinal Cord Injured patients (SCI) we design this study.
Methods: in this study the efficacy of electrical stimulation in treating spasticity of l0 patients with SCI, Compex was applied to the dermatoms belonging to the selected spastic muscle groups. Spasticity was assessed Aschworth score, Spasm frequency scale (Modified for Penn), Spasm severity, interference with function, Painful spasm, Clonus score, Deep tendon reflex, Plantar stimulation response, before and after one month therapy duration.
Results: Compex was found to produce noticeable decrease of spasticity in 82 % of patients, (p<0.01).
Conclusion: We conclude that this myoelectric stimulation may enhance rehabilitation efforts by providing inhibition of spastic hypertony.
RECURRENT INHIBITION IN PATIENTS WITH SPASTICITY: RENSHAW CELL CHANGES ITS EXCITABILITY ACCORDING TO THE AFFERENT INPUT FROM THE PROPRIOCEPTIVE ORGANS

We have measured recurrent inhibition using H-reflex recovery procedure (Pierrot-Deseilligny and Bussel, 1975). In this method supramaximal test shock allows selective assessment of that portion of the motor neuron pool which has just responded to the conditioning stimulus, because in the remaining motor axons the antidromic activity blocks the orthodromic impulse.
In ten healthy subjects the test responses were averaged 21, 41 and 35 % of the conditioning response at 5, 15 and 25 ms inter-stimulous interval, respectively. In four cases of chronic spinal cord damage with spasticity, the test responses were suppressed to 12, 17 and 10 % at 5, 15 and 25 ms. And we have experienced the reduction of recurrent inhibition after tendon elongation.
These findings suggest that Renshaw cell increases its excitability for the purpose of decreasing the muscle tone according to the afferent input from peripheral nerve. Segmental mechanism might act larger effect than supraspinal control.
