[An experimental study on denervated XXXX --effect of electrostimulation and comparison with immobilization @entity2057 ].

@entity35 @entity2057 @entity194
The efficacy of causing @entity2057 was compared among denervation, arthrodesis and tenotomy in @entity35 anterior tibial muscle. Reduction of wet weight was most pronounced in denervated muscle and least in arthrodesed muscle. Histochemical investigation by ATPase stain revealed that @entity194 of Type 1 and Type 2 fiber was more severe in denervated muscle group than in the other two groups. Type 2 fiber @entity194 was dominant in denervated muscle and in arthrodesed muscle. Type 1 fiber @entity194 was dominant in tenotomized muscle. The effect of electrostimulation on denervated muscle was investigated. Electrostimulation significantly reduced the degree of denervation @entity194 . Four weeks after severance of peroneal nerve, tibial nerve-crossing was done and electrostimulation was continued for eight weeks. Recovery of wet weight of re-innervated muscle with electrostimulation was significantly better than that without electrostimulation. Electrostimulation applied to denervated muscle reduced the progress of @entity194 and improved the recovery after nerve repair.
