Abstract
ABSTRACT Introduction. Earlier studies have shown that brain stimulation by means of repetitive Transcranial Magnetic Stimulation (rTMS) over the primary motor cortex can decrease the motor impairments in Parkinson's disease (PD). The present study focused on the clinical relevance of rTMS in the treatment of PD. Method. Thirteen PD patients received a minimum of 10 sessions of 2,000 pulses 5 Hz rTMS over the hand and leg area over the primary motor cortex, with a stimulation intensity of 120% of the motor threshold. In our analysis an effect could be considered as clinically relevant if the quality of life (QoL) improved with 30% or more. Results. Paired-sample t-tests revealed a significant improvement of Unified Parkinson's Disease Rating Scale score, walking speed, and mood. A minority of the patients (38%) who underwent rTMS showed an improvement in QoL of greater than 30%. The improvements on QoL correlated significantly to scores of motor improvements on the Unified Parkinson's Disease Rating Scale...
