OBJECTIVE: To investigate short-term and long-term effects of repetitive
peripheral magnetic stimulation (rpMS) on spasticity and motor function. DESIGN:
Monocentric, randomized, double-blind, sham-controlled trial. SETTING: Neurologic
rehabilitation hospital. PARTICIPANTS: Patients (N=66) with severe hemiparesis
and mild to moderate spasticity resulting from a stroke or a traumatic brain
injury. The average time +/- SD since injury for the intervention groups was 26
+/- 71 weeks or 37 +/- 82 weeks. INTERVENTIONS: rpMS for 20 minutes or sham
stimulation with subsequent occupational therapy for 20 minutes, 2 times a day,
over a 2-week period. MAIN OUTCOME MEASURES: Modified Tardieu Scale and
Fugl-Meyer Assessment (arm score), assessed before therapy, at the end of the
2-week treatment period, and 2 weeks after study treatment. Additionally, the
Tardieu Scale was assessed after the first and before the third therapy session
to determine any short-term effects. RESULTS: Spasticity (Tardieu >0) was present
in 83% of wrist flexors, 62% of elbow flexors, 44% of elbow extensors, and 10% of
wrist extensors. Compared with the sham stimulation group, the rpMS group showed
short-term effects on spasticity for wrist flexors (P=.048), and long-term
effects for elbow extensors (P<.045). Arm motor function (rpMS group: median 5
[4-27]; sham group: median 4 [4-9]) did not significantly change over the study
period in either group, whereas rpMS had a positive effect on sensory function.
CONCLUSIONS: Therapy with rpMS increases sensory function in patients with severe
limb paresis. The magnetic stimulation, however, has limited effect on spasticity
and no effect on motor function.
