Repetitive Transcranial Magnetic Stimulation (rTMS) Treatment of Post-Stroke Spasticity
In Brief
A clinical study evaluating repetitive Transcranial Magnetic Stimulation (rTMS) and Sham repetitive Transcranial Magnetic Stimulation for Spasticity. Completed, enrolled 4 participants across 1 site.
Detailed Summary
Spasticity is a common complication of stroke affecting quality of life. Spasticity involves exaggerated stretch reflexes that create stiffness in muscles with associated loss of motion and functional control. Traditional treatments involve range of motion, medications, and sometimes surgery. Each of these has its own limitations, which has invited exploration of alternative modes of treatment. One such treatment with the potential to benefit spasticity is repetitive Transcranial Magnetic Stimulation (rTMS). The purpose of this study is to determine whether patients with upper limb spasticity as a consequence of a chronic stroke can benefit from stimulation of the non-affected hemisphere of the brain with low-frequency (inhibitory) repetitive Transcranial Magnetic Stimulation (rTMS), potentially leading to a reduction of spasticity and clinical improvement in upper limb function.
Study Details
Timeline
Interventions
The treatment arm will consist of 3 daily treatment sessions. One treatment session in this study with real rTMS will consist of 600 pulses of 1Hertz rTMS at an intensity of 90% of resting motor threshold (duration 10 minutes) applied to the primary motor area of the contralesional hemisphere.
Sham rTMS utilizes a coil that produces identical noise and tactile sensation to the real coil, but does not emit a magnetic field (0% intensity). Duration and frequency of auditory and tactile stimulation will be identical to the real intervention.
