Repetitive transcranial magneticstimulation rTMS has recently been demonstrated to improve motor functionafter stroke. However, no study has yet tested the synergetic effects ofphysical exercise on rTMS in clinical settings. We investigated the effect of a6-session course of low frequency rTMS on contralesional primary motor cortexcombined with range-of motion ROM exercise on paretic hand function in femalestroke patients. This was a single-blind study of the effects of rTMS with orwithout ROM exercise in female hemiplegic patients after stroke. All patients underwentrTMS on the contralesional primary motor cortex for 15 minutes and ROM exerciseon the paretic hand. The cortical excitability determined by the amplitude andlatency of the motor evoked potential MEP was measured in both first dorsalinterosseous FDI muscles. We also evaluated arm function using Box and Block,arm reach, 9-hole pegboard, power grip, and pinch grip force tests. TherTMS-induced MEP amplitude of the paretic side significantly increased whereasthe non-paretic side showed a decrease through every session. However, the MEPlatency significantly increased on the non-paretic hand at post-rTMS with exercise, but atendency of decrement on paretic hand at same application. Motor function showedimprovement in the 9-hole pegboard and arm reach tests at post-rTMS withexercise on the paretic side compared with the non-paretic side. A significantcorrelation was especially noted between motor function and MEP on the pareticside of stroke patients. Low frequency rTMS with ROM exercise improved hand function after stroke. This may, in part,result in additional rehabilitation in stroke patients.
