What is Infantile Hemiparesis?
Infantile Hemiparesis refers to weakness or reduced movement control affecting one side of a child’s body.
The word:
Hemi means one side.
Paresis means weakness or partial loss of voluntary movement.
The affected side may involve the:
Arm
Hand
Leg
Foot
Face
The severity can vary significantly. Some children may have mild weakness that mainly affects fine hand movements or walking, while others may have more noticeable difficulty using one side of the body.
Infantile hemiparesis often results from damage to or abnormal development of areas of the brain responsible for controlling movement.
Because each side of the brain mainly controls movement on the opposite side of the body:
A Left-Sided Brain Injury may cause weakness on the right side of the body.
A Right-Sided Brain Injury may cause weakness on the left side of the body.
Depending on the underlying cause, the condition may be present from early life or become noticeable as the child develops and begins to reach movement milestones.
Infantile hemiparesis may be:
Congenital
The brain difference or injury occurs before or around birth.
Acquired
The weakness develops after birth due to a condition such as stroke, infection, traumatic brain injury, or another neurological event.
Early assessment and appropriate rehabilitation can help support the child’s development and functional abilities.
What Are The Symptoms Of Infantile Hemiparesis?
Symptoms vary depending on the affected areas and severity of the condition.
Weakness on One Side of the Body: One arm, hand, leg, or side of the face may appear weaker.
Reduced Use of One Hand: The child may consistently prefer one hand and use the other hand less during play or daily activities.
Early Hand Preference: A strong preference for one hand at an unusually early age may be a sign that requires assessment.
Difficulty Reaching and Grasping: The affected hand may have reduced strength, coordination, or control.
Reduced Fine Motor Skills: Tasks such as holding toys, drawing, buttoning clothes, or using utensils may be difficult.
Reduced Arm Movement: The affected arm may be held in an unusual position or used less during movement.
Increased Muscle Tone: Muscles may feel stiff or tight due to spasticity.
Reduced Muscle Tone: Some children may have reduced muscle tone or poor muscle activation.
Stiffness in Joints: Reduced movement may contribute to muscle and joint tightness.
Difficulty Crawling: Crawling may be asymmetrical or delayed.
Delayed Walking: Independent walking may develop later in some children.
Abnormal Walking Pattern: The child may walk differently due to weakness, stiffness, poor balance, or reduced foot control.
Toe Walking: The affected side may show increased toe walking.
Foot Drop: Difficulty lifting the front of the foot may cause the toes to drag.
Poor Balance: Standing, walking, turning, or playing on uneven surfaces may be more difficult.
Reduced Coordination: Movements may appear less smooth or controlled on the affected side.
Difficulty with Two-Handed Activities: Tasks requiring both hands may be challenging.
Frequent Falls: Reduced balance and movement control may increase the risk of falls.
Difficulty with Everyday Activities: Dressing, bathing, eating, writing, and playing may require additional support.
What Are The Causes Of Infantile Hemiparesis?
Infantile hemiparesis occurs due to a condition affecting the areas of the brain responsible for movement control.
Hemiplegic Cerebral Palsy: One of the common causes of long-term weakness affecting one side of the body.
Perinatal Stroke: A stroke occurring before, during, or shortly after birth can affect movement development.
Childhood Stroke: A stroke occurring later during childhood can lead to weakness on one side.
Brain Injury Before Birth: Abnormal brain development or injury during pregnancy may affect motor function.
Birth-Related Brain Injury: Certain complications around the time of birth can affect the brain.
Traumatic Brain Injury: A significant head injury may damage areas of the brain involved in movement.
Brain Infection: Conditions such as encephalitis or meningitis may affect the brain and nervous system.
Brain Tumours or Surgery: A brain tumour or neurosurgical treatment may sometimes affect movement pathways.
Vascular Abnormalities: Problems involving blood vessels supplying the brain may cause neurological injury.
Other Neurological Conditions: Various disorders affecting the brain and nervous system may lead to hemiparesis.
The exact cause should be identified whenever possible because treatment and long-term management depend on the underlying neurological condition.
Diagnosis Of Infantile Hemiparesis
Developmental History: A healthcare professional will ask about pregnancy, birth, developmental milestones, movement patterns, hand preference, and when symptoms were first noticed.
Medical History: Previous illnesses, seizures, injuries, infections, strokes, or other neurological events are reviewed.
Neurological Examination: A doctor may assess muscle strength, tone, reflexes, coordination, sensation, and movement patterns.
Developmental Assessment: The child’s gross motor, fine motor, communication, and other developmental skills may be assessed.
Physiotherapy Assessment: A paediatric physiotherapist may assess posture, muscle tone, joint range of motion, balance, walking, transfers, functional mobility, and movement quality.
Hand Function Assessment: Fine motor skills, grasp, release, coordination, and use of both hands may be evaluated.
Gait Analysis: Walking may be observed to identify asymmetry, toe walking, foot drop, reduced weight-bearing, or other movement differences.
MRI Brain: MRI may be used to identify previous brain injury, developmental abnormalities, stroke, or other structural causes.
CT Scan: A CT scan may be used in selected situations, particularly in certain acute medical circumstances.
Other Investigations: Additional blood tests, genetic testing, metabolic investigations, or other assessments may be required depending on the suspected cause.
Multidisciplinary Assessment: Paediatricians, paediatric neurologists, physiotherapists, occupational therapists, speech therapists, and other specialists may contribute to assessment and treatment.
Treatment Of Infantile Hemiparesis
Treatment depends on the underlying cause, severity of symptoms, the child’s age, and individual developmental needs.
Physiotherapy: Helps address mobility, balance, strength, walking, posture, and functional movement.
Occupational Therapy: Supports hand function, fine motor skills, self-care, play, and everyday independence.
Constraint-Induced Movement Therapy: In selected children, therapy may encourage increased use of the affected arm and hand.
Bimanual Training: Exercises and activities may help improve the coordinated use of both hands.
Strengthening Exercises: Age-appropriate exercises may help improve functional muscle strength.
Stretching and Range of Motion: Regular movement may help manage muscle tightness and maintain joint mobility.
Balance and Coordination Training: Activities may help improve stability, movement control, and confidence.
Gait Training: Therapy may help improve walking ability, foot placement, weight transfer, and overall movement efficiency.
Orthotic Management: Ankle-foot orthoses or other devices may be recommended to support alignment and mobility.
Spasticity Management: A specialist may recommend medication, injections, or other treatment for significant muscle spasticity.
Speech and Language Therapy: Support may be required if speech, communication, or swallowing is affected.
Treatment of Underlying Conditions: Conditions such as epilepsy or other neurological problems require appropriate medical management.
Surgical Treatment: Selected children may require orthopaedic or neurological surgery depending on their individual condition.
Family Education: Parents and caregivers may receive guidance on safe handling, positioning, movement practice, and activities to support development.
