  • influence of spinal cord lesion level and severity on h reflex excitability and Recovery Curve
    Muscle & Nerve, 2015
    Co-Authors: Hatice Kumru, Josep Vallssole, Sergiu Albu, Narda Murillo, Josep Maria Tormos, Joan Vidal
    Abstract:

    Introduction Changes in spinal reflexes can result from alterations in the spinal cord and descending pathways. We studied whether H-reflex excitability and its Recovery depend on the level and/or severity of spinal cord injury (SCI). Methods The soleus Hmax and Mmax responses and the H-reflex Recovery Curve (HRC) at interstimulus intervals (ISIs) ranging from 50 to 1,000 ms were recorded in 38 SCI individuals and 18 healthy subjects. Results Amplitude of Mmax correlated with level and severity of lesion (smaller amplitude correlated with more severe SCI or with more caudal lesion). Hmax/Mmax correlated only with age in the SCI group. HRC was increased significantly in complete SCI at ISIs   200 ms with respect to healthy subjects. Conclusions The changes in spinal reflexes as measured by the H-reflex and its Recovery Curve after SCI depend on the severity, but not on the level of the lesion. Muscle Nerve 52: 616–622, 2015

  • excitability Recovery Curve of the sympathetic skin response in healthy volunteers and patients with palmar hyperhidrosis
    Clinical Neurophysiology, 2000
    Co-Authors: Davide Manca, Josep Vallssole, M.a. Callejas
    Abstract:

    Abstract Objectives : Patients with primary palmar hyperhidrosis (PPH) might exhibit hyperexcitability of the reflex circuits involved in sweating. We hypothesized that this hyperexcitability could become evident in the study of the excitability Recovery Curve of the sympathetic sudomotor skin response (SSR). Methods : In 10 patients with PPH and 10 healthy volunteers used as control subjects, we recorded the SSR in the palm of the right hand to pairs of median nerve electrical shocks separated by inter-stimuli intervals (ISIs) ranging from 0.5 to 3.5 s. The amplitude of the SSR generated by the second stimulus (SSR2) was expressed as a percentage of that generated by the first (SSR1), and compared between control subjects and patients for each ISI. Results : None of the control subjects showed a Recovery of the SSR for ISIs of 1.5 s or less. On the contrary, patients showed a statistically significant enhancement of the SSR excitability Recovery Curve, with onset of Recovery at 1.5 s in 5 patients. Two patients showed a double peak response to single electrical stimulation and were not considered in the calculation of the SSR Recovery Curve. Mean excitability Recovery percentages were larger in patients than in control subjects at ISIs of 2, 2.5 and 3 s. Conclusions : The enhancement of the SSR Recovery Curve in patients with PPH suggests hyperexcitability of the somatosympathetic polisynaptic pathway involved in sweating. This could partly underlie the pathophysiology of PPH.
