Abstract:
Objective:To observe any impact of the repeated application of high-frequency peripheral magnetic stimulation (rPMS) on the recovery of motor function among hemiplegic survivors of an intracerebral hemorrhage. Also to explore the therapeutic mechanism involved.Methods:Sixty-two hemiplegic survivors of an intracerebral hemorrhage were randomly assigned to an observation group or a control group, each of 31. Both groups received standard medical treatment and early rehabilitation, but the observation group also received high-frequency rPMS applied to their upper and lower limbs. Before and after two weeks of the treatment, everyone′s motor functioning was assessed using the Fugl-Meyer Assessment (FMA). Walking ability was quantified using functional ambulation classification (FAC). And ability in the activities of daily living was rated using the modified Barthel Index (MBI). The amplitudes and latencies of motor evoked potentials (MEPs) induced by transcranial magnetic stimulation and recorded from the abductor pollicis brevis of the affected side were also analyzed..Results:After the treatment, significant improvement was observed in both groups′ upper and lower limb FMA scores, MBI scores, FAC grades, and in their MEP amplitudes and latencies. On average, however, the observation group′s results were significantly better than those of the control group. Moreover, no significant adverse reactions were found in either group during the treatment.Conclusions:Early rPMS intervention significantly enhances the recovery of limb function after an intracerebral hemorrhage, possibly through its modulation of cortical excitability.
