TI  - Influence of spinal cord lesion level and severity on H-reflex excitability and 
      recovery curve.

AB  - 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 < 500 ms and in 
      incomplete 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.
