Effect of continuous inhibition of Ia fiber activity on spasticity symptom and Ia-α motoneuron connection after spinal cord injury
Spasticity is motor dysfunction after Spinal cord injury (SCI). Current treatments of spasticity focusing on muscle contraction have some issues (Figure.1). Phospholipase D coupled metabotropic receptor expresses in Ia fiber endings in muscle spindle and enhances Ia fiber activity. Dihydroxyphenyl glycine (DHPG) work as the antagonist of it. We hypothesized that inhibition of Ia fiber activity using DHPG reduce spasticity. Aim of this study is to confirm effect of continuous inhibition of Ia fiber activity on spasticity symptom and Ia-α connection after SCI. SCI models were made by semi-transe
