About this study
Official title: Effect of Repetitive Transcranial Magnetic Stimulation Over Contralesional Dorsal Premotor Cortex on Post Stroke Upper Limb Spasticity
The reticulospinal pathway (RSP) is at the center of spasticity mechanism. The RSP indirectly synapses with motor neurons via interneurons in the ventromedial intermediate zone in both halves of the spinal cord, and directly synapses with motor neurons of proximal extremity muscles. The main motor cortex region controlling unilateral RSP is the premotor cortex. That is, a single limb is represented in both premotor cortices. This suggests theoretically that if the corticoreticular pathway controlling RSP is modulated by dorsal premotor cortex stimulation, there may be a change in the regulation of the intraspinal network regulating the stretch reflex. Therefore, the hypothesis in this study is that the application of repetitive transcranial magnetic stimulation (rTMS) over the contralesional dorsal premotor cortex in chronic stroke patients changes the severity of spasticity.
Read the detailed description
Spasticity is a disorder characterized by increase in velocity-related muscle tone as a part of upper motor neuron syndrome. Although the mechanisms underlying stroke-related spasticity have not been fully understood, the current view is that spasticity is related to an imbalance between descending excitatory and inhibitory systems that regulate spinal stretch reflex and associated with abnormal intraspinal processes. The reticulospinal pathway (RSP) is at the center of this mechanism called cortical disinhibition. The dorsal RSP, which has an inhibitory effect on the spinal stretch reflex, originates from the medullary reticular formation and is under cortical control. In contrast to dorsal RSP, medial RSP which is not under the control of motor cortex originates from pontine reticular formation,and has an excitatory effect on spinal stretch reflex. The main motor cortex region controlling unilateral dorsal RSP is the premotor cortex. Unilateral RSP indirectly synapses with motor neurons via interneurons in the ventromedial intermediate zone in both halves of the spinal cord, and directly synapses with motor neurons of proximal extremity muscles. That is, a single limb is represented in both premotor cortices. This suggests theoretically that if the corticoreticular pathway controlling dorsal RSP is modulated by dorsal premotor cortex stimulation, there may be a change in the regulation of the intraspinal network regulating the stretch reflex. Furthermore, in stroke patients with severe motor impairment, the relationship between high cortical centers and the primary motor cortex is more in the form of facilitation rather than interhemispheric inhibition between the primary motor cortices. In other words, stimulation of one side premotor cortex may affect motor impairment and spasticity by affecting primary and high motor cortical centers of both hemispheres and both halves of the spinal cord. Therefore, the hypothesis in this study is that the application of repetitive transcranial magnetic stimulation (rTMS) over the contralesional dorsal premotor cortex in chronic stroke patients changes the severity of spasticity. Based on this hypothesis, our aim is to investigate the effect of rTMS over the contralesional dorsal premotor cortex on the severity of spasticity in patients with chronic stroke with moderate to severe upper extremity spasticity.

Repetitive transcranial magnetic stimulationDevice
Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive intervention that uses magnetic fields to stimulate nerve cells to improve the symptoms of a variety of disorders, including stroke-related motor impairment.
| Study group | Role | What they receive |
|---|---|---|
| Excitatory repetitive transcranial magnetic stimulation group | Experimental | One session of repetitive transcranial magnetic stimulation (rTMS) treatment with 10 Hz frequency will be applied to the contralesional dorsal premotor cortex. Application will be performed with Neurosoft-Neuro MS / D device. 90% of the motor threshold will be used in the stimulation. Stimulation is planned for a total of 15 minutes and a total of 1500 beats in the form of a 5 seconds 10 Hz stimulation followed by a 25 seconds interval. Receives: Device: Repetitive transcranial magnetic stimulation |
| Inhibitory repetitive transcranial magnetic stimulation group | Experimental | One session of repetitive transcranial magnetic stimulation (rTMS) treatment at 1 Hz frequency will be applied to the contralesional dorsal premotor cortex. Application will be performed with Neurosoft-Neuro MS / D device. 90% of the motor threshold will be used in the stimulation. Stimulation is planned for a total of 25 minutes and a total of 1500 beats in the form of 1 Hz stimulation. Receives: Device: Repetitive transcranial magnetic stimulation |
| Sham repetitive transcranial magnetic stimulation group | Sham comparator | Single session of sham application for a total of 25 minutes. Sham application will be performed by holding the probe of the device vertically to the vertex. The device will be operated at the lowest operating power of 1 to produce the same stimulation sounds like the active application. The device operating at this power is not likely to give any stimulation due to the probe being held upright. Receives: Device: Repetitive transcranial magnetic stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Modified Ashworth Scale
The modified Ashworth Scale is a scale that clinically evaluates the presence and severity of muscle tone increase. It is an ordinal scale that evaluates spasticity at six levels between 0 and 4 (0, 1, 1+, 2, 3, 4). The severity of spasticity increases as the score increases. Score 0 indicates no increase in muscle tone, while score 4 indicates that the affected part is rigid. Six levels between 0 and 5 (0, 1, 2, 3, 4, 5) will be used in statistical analysis. The score of 1+ will be treated as 2, 2 as 3, 3 as 4 and 4 as 5.
Measured: Pre-intervention (baseline) and immediately after intervention (post-intervention), up to 45 minutes
Secondary outcomes (1)
F wave parameters
F-wave is one of the late responses caused by antidromic stimulation of alpha motor neurons. It occurs following supramaximal electrical stimulation of peripheral motor nerves following M response. The F wave indicates the transmission from the stimulated point to the motor neuron and back to the recording electrode. Increased F wave frequency, increased F / M ratio and amplitude has been considered to indicate the increased motor neuron excitability.
Measured: Pre-intervention (baseline) and immediately after intervention (post-intervention), up to 45 minutes

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The reticulospinal pathway (RSP) is at the center of spasticity mechanism. The RSP indirectly synapses with motor neurons via interneurons in the ventromedial intermediate zone in both halves of the spinal cord, and directly synapses with motor neurons of proximal extremity muscles. The main motor cortex region controlling unilateral RSP is the premotor cortex. That is, a single limb is represented in both premotor cortices. This suggests theoretically that if the corticoreticular pathway controlling RSP is modulated by dorsal premotor cortex stimulation, there may be a change in the regulation of the intraspinal network regulating the stretch reflex. Therefore, the hypothesis in this study is that the application of repetitive transcranial magnetic stimulation (rTMS) over the contralesional dorsal premotor cortex in chronic stroke patients changes the severity of spasticity.
