rTMS in Spastic Hemiplegic Cerebral Palsy Children

Study Overview
=================
Brief Summary
-----------------
The aim of the work is to study the role of repetitive transcranial magnetic stimulation (rTMS) in spastic hemiplegic cerebral palsy in a Sample of Egyptian Children.

Detailed Description
-----------------
Prior to start of rTMS therapy, Gross Motor Function Classification System (GMFCS) will be employed on the participants to classify gross motor function. Also, Modified Ashworth Scale (MAS) scoring will be employed on the participants to access spasticity on selected muscles namely, hamstring, soleus, gastrocnemius and adductor of lower limb; and bicep, supinator and wrist extensor of upper limb. rTMS frequency of 10 Hz will be delivered to each of the participants in the study group for 15 minutes per session. Each session will be administered once daily for 2 days a week for 4 weeks. 1500 pulses (50 pulses per train with total 30 trains having inter- train delay of 25 seconds) per session will be provided with the coil placed on the contralateral primary motor cortex (M1) which is known to produce modulatory effect on muscle tightness of the limbs (Rajak et al. 2017). rTMS frequency of 10 Hz was kept constant based on previous studies with 5 Hz and 10 Hz (Anttila et al. 2008) (Rossi 2009). Each session will be followed by physical therapy (PT) according to physiotherapy protocol. After completion of therapeutic programs (after 4 weeks), the participants will be asked to undergo post assessment of Gross Motor Function Classification System (GMFCS), and Modified Ashworth Scale (MAS) scoring on exactly the same muscles as recorded previously. Both PT and rTMS sessions will be administered by trained professionals who was kept blinded to the research protocols used in the study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Study Group<br>The children in this group will receive traditional treatment of hemiplegic CP including medical treatment and physiotherapy in addition to repetitive transcranial magnetic stimulation sessions for 4 weeks. | Device: Repetitive Transcranial Magnetic Stimulation<br>* TMS device will deliver repetitive trains of magnetic pulses using Magstim Rapid 2 with angulated figure of eight shaped coil. The device comprised two-channel Neuro-EMG-MS digital system for determining the motor threshold of the patients that will be used for establishing the threshold intensity for stimulation. The figure of eight-shaped coil generated a magnetic field of up to 4 Tesla that penetrates the cranium, enters into the soft tissue of the brain and henceforth stimulates the motor neurons.<br>|
| No Intervention: Control Group<br>The children in this group will receive traditional treatment of hemiplegic CP including medical treatment and physiotherapy for 4 weeks. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in muscle spasticity | Assessment tools: Modified Ashworth Scale. It grades muscle spasticity between 0 to 4. Higher score mean a worse outcome. | 1 week following end of treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in gross motor function | Gross Motor Function Classification System (GMFCS). It includes five levels and four age bands. Classifications are made based on the child's self-initiated movements with emphasis on sitting and walking. Higher score mean a worse outcome. | 1 week following end of treatment |
