Repetitive Transcranial Magnetic Stimulation Versus Botulinum Injection on Spasticity on Children With Diplegic Cerebral Palsy

January 22, 2024 updated by: Rana Nabil Hussein Mohamed, MTI University

Combined Effect of Repetitive Transcranial Magnetic Stimulation and Botulinum Injection on Spasticity and Motor Functions of Children With Diplegic Cerebral Palsy

This trial will enroll 75 children with spastic diplegic cerebral palsy both matched in age, sex, degree of disability and cognitive functions with the same exclusion criteria undergoing the same physical therapy. All enrolled children will undergo routine physical therapy program and will be divided into three groups (n = 25 per group) according treatment methods. Group A: children will be given local injections of botulinum toxin type ,Group B: children will be given repetitive transcranial magnetic stimulation on the affected side; Group C: children will be given local injections of botulinum toxin type A combined with repetitive transcranial magnetic stimulation , the three groups will take physical therapy (PT) of 45 minutes duration 4 days a week for 3 months .The grade of spasticity will be assessed by using Modified Ashworth scale and M/H ratio by using EMG. The grade of motor function will assessed by using Gross Motor Function Classification System (GMFCS).

Detailed Description

This trial will enrol 75 children with spastic diaplegic cerebral palsy with both sex, degree of disability and cognitive functions with the same exclusion criteria and the same physical therapy program. All enrolled children will undergo routine physical therapy program and will be divided into three groups (n = 25 per group) according treatment methods. Group A: children will be given local injections of botulinum toxin type ,Group B: children will be given repetitive transcranial magnetic stimulation on the affected side; Group C: children will be given local injections of botulinum toxin type A combined with repetitive transcranial magnetic stimulation , the three groups will take physical therapy (PT) of 45 minutes duration 4 days a week for 3 months.

They will diagnosed based on history taking including perinatal, developmental, and family history, general and neurological examination. The included children with clinical diagnosis of moderate spastic diplegic cerebral palsy with a MAS (1, 1+, 2) and GMFCS (II, III, IV) will participated in this study. On the contrary, children with dyskinetic CP, mental retardation, previous ankle or knee surgery, uncontrolled epileptic seizure or contracture will excluded

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Botox for spasticity
Botox for spasticity in lower limbs in cerebral palsy children
Drug: botulinum toxin A
Botulinum Neurotoxin A (BoNT-A) Injections will administered directly into the bulk of the muscles, with two injection sites at each head of the gastrocnemius and two sites into the medial hamstring. one vial of BoNT-A in 2 mL of 0.9% sodium chloride solution. followed by a 3-month rehabilitation program. The entire intervention including rTMS, BoNT-A, and rehabilitation training program spanned a period of three months.
Other: Rehabilitation Training Protocol
Rehabilitation Training Protocol: As part of the study protocol, all participating children underwent a comprehensive weekly routine rehabilitation training program. Training Schedule: sessions will conduct for duration of 45 minutes. Training occurred four days a week.
Experimental: transcranial magnetic stimulation for spasticity
transcranial magnetic stimulation for spasticity in cerebral palsy children
Other: Rehabilitation Training Protocol
Rehabilitation Training Protocol: As part of the study protocol, all participating children underwent a comprehensive weekly routine rehabilitation training program. Training Schedule: sessions will conduct for duration of 45 minutes. Training occurred four days a week.
Device: Transcranial Magnetic Stimulation
Repeated Transcranial Magnetic Stimulation (rTMS) Stimulation coil will strategically place on the primary motor cortex (M1), The patients received 1500 pulses per session, two sessions per week for 3 months, in a combination with 3-month rehabilitation program.
Experimental: Botox combined with transcranial magnetic stimulation for spasticity

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
modified aswthor scale
Time Frame: 3 months
Modified Ashworth Scale (MAS): The MAS measures the resistance and spasticity in the joint during passive movement. The resistance is scored from 0 to 5 (0 the least severe to 5 the most severe
3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gross Motor Function Classification System
Time Frame: 3 months
Gross Motor Function Classification System (GMFCS): The GMFCS provides a standardized system to classify the gross motor function of children with CP into five levels (level I the least severe to level V the most severe)
3 months

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Electromyography
Time Frame: 3 months
The Hofmann's reflex or H-reflex, as measured by electromyography (EMG), has been used to assess spasticity. The H-reflex measures the threshold spinal reflex reaction in muscles after electrical stimulation of the peripheral nerve, believed to be indicative of alpha motor neuron excitability. People with spasticity have increased alpha motor neuron excitability and increased H-reflex amplitude and following M-response, thus allowing measurement of the H-reflex, the M-response, and the H/M ratio
