Comparison of low frequency rTMS and rehabilitation combination therapy with rehabilitation on motor function and grip force of the upper limbs in hemiplegic patients

Disabilities of upper extremities, as a sequel of stroke, often result in permanent functional complications which have received less attention in comparison to lower limb disabilities. Magnetic stimulation is a new therapeutic method which is used for induction of currents in the brain. The aim of this study was to compare the effect of magnetic stimulation on the wrist and elbow joints movements and grip force with that of routine rehabilitation. 12 hemiplegic patients were assigned to two groups. Patients in group I, received routine rehabilitation with placebo magnetic stimulation, and patients in group II, received magnetic stimulation with routine rehabilitation for 10 sessions, 3 times a week. Pre and post treatment evaluations were performed by use of Barthel index, Fugl-Meyer Motor Impairment Scale and dynamometer. In group I, Barthel and Fugl-Meyer indexes showed significant improvement, but no significant improvement noted in the rate of grip force. Group II, showed significant improvement in Barthel and Fugl-Meyer indexes and rate of grip force. When conventional treatment is not effective, rTMS can improve force and function of hand muscles in chronic hemiplegic patients.
