Motor Function & Movement Assessment

Motor function and movement assessment in children with cerebral palsy (CP) involves evaluating their ability to control and coordinate movements. CP affects muscle tone, posture, and motor skills due to brain damage occurring before, during, or shortly after birth. Assessments help in understanding a child’s motor abilities, guiding interventions, and tracking progress over time.


Why is Motor Function Assessment Important?

  1. Diagnosis and Classification
    • Helps in identifying the severity and type of CP (spastic, dyskinetic, ataxic, or mixed).
    • Guides clinicians in categorizing children into functional levels using standardized scales.
  2. Personalized Treatment Planning
    • Supports healthcare professionals in developing tailored physical therapy, occupational therapy, and assistive technology plans.
  3. Monitoring Progress and Adaptation
    • Assists in tracking improvements or challenges over time, allowing for therapy adjustments.
  4. Predicting Future Mobility Needs
    • Helps in determining whether a child may need assistive devices like walkers or wheelchairs.
  5. Enhancing Quality of Life
    • Aims to maximize independence and participation in daily activities, school, and play.

Measuring tools to assess motor function & movement

Gross Motor Function Classification System (GMFCS) – Classifies mobility into five levels.

Gross Motor Function Measure (GMFM-66 & GMFM-88) – Evaluates changes in gross motor function.

Manual Ability Classification System (MACS) – Assesses hand function for daily activities.

Bimanual Fine Motor Function (BFMF) – Evaluates fine motor function.

Hammersmith Infant Neurological Examination (HINE) – Screens for early motor impairments.

Bayley Scales of Infant and Toddler Development (Bayley-4) – Assesses motor, cognitive, and language development.

Test of Infant Motor Performance (TIMP) – Assesses early motor control.

Assessment ToolPurposeFocusAge GroupKey FeaturesStrengthsLimitations
Gross Motor Function Classification System (GMFCS)Classifies mobility into five levelsMobility function across different settingsChildren with cerebral palsy (CP)Five levels of mobility from independent walking to the need for a wheelchair.Easy to administer, widely used in clinical and research settings.Does not provide detailed information on motor skills beyond mobility.
Gross Motor Function Measure (GMFM-66 & GMFM-88)Evaluates changes in gross motor functionGross motor abilities (sitting, standing, walking)Children with CP or other neurological conditionsGMFM-88 has 88 items; GMFM-66 has 66 items for assessing motor function.Sensitive to change over time, useful for monitoring progress.Requires time to administer; may be challenging for children with severe impairments.
Manual Ability Classification System (MACS)Assesses hand function for daily activitiesHand function in activities of daily livingChildren with CPFive levels of manual ability ranging from independent use of hands to no hand use.Simple, reliable, and widely accepted.Does not assess the quality of movements or dexterity beyond classification.
Bimanual Fine Motor Function (BFMF)Evaluates fine motor functionAbility to use both hands in activitiesChildren with CPAssesses fine motor function in a bimanual context, with a focus on coordination.Useful for identifying asymmetries between hands.May be difficult to assess in children with severe impairments.
Hammersmith Infant Neurological Examination (HINE)Screens for early motor impairmentsNeurological status, early motor developmentInfants and young children (0-2 years)Assesses 26 items, including reflexes, movements, and posture.Early identification of motor impairments, easy to administer.Limited scope, focuses primarily on neurological impairments.
Bayley Scales of Infant and Toddler Development (Bayley-4)Assesses motor, cognitive, and language developmentCognitive, motor, language, and social-emotional developmentInfants and toddlers (1-42 months)Measures cognitive, language, motor, and social-emotional domains.Comprehensive and widely used in developmental assessment.Time-consuming, may be difficult for children with severe delays.
Test of Infant Motor Performance (TIMP)Assesses early motor controlMotor control, posture, and movement patternsInfants (up to 4 months)Focuses on postural control and early movement abilities.Excellent for early intervention; sensitive to early changes in motor control.May not be applicable for older children, limited to infants.

Which one to use?

Clinical ScenarioBest Tool to UseWhy
Assessing overall mobility in children with cerebral palsyGross Motor Function Classification System (GMFCS)GMFCS is specifically designed to classify mobility levels in children with cerebral palsy.
Tracking progress in gross motor function over timeGross Motor Function Measure (GMFM-66 & GMFM-88)These measures are sensitive to changes in gross motor function, making them ideal for monitoring progress.
Assessing fine motor skills related to daily activitiesManual Ability Classification System (MACS)MACS evaluates hand function in a real-world context, helping determine a child’s ability to perform daily tasks.
Evaluating bimanual fine motor coordinationBimanual Fine Motor Function (BFMF)BFMF assesses the ability to use both hands together, providing insight into hand coordination and fine motor function.
Screening for early neurological or motor impairmentsHammersmith Infant Neurological Examination (HINE)HINE is designed to screen for early motor impairments in infants, identifying neurological deficits.
Assessing cognitive, language, and motor development in infants and toddlersBayley Scales of Infant and Toddler Development (Bayley-4)Bayley-4 is a comprehensive tool for assessing developmental milestones across cognitive, motor, and language domains.
Assessing early motor control in infantsTest of Infant Motor Performance (TIMP)TIMP is sensitive to early motor control issues and is excellent for infants under 4 months old.

Summary of “Which One to Use”:

  • GMFCS is ideal for classifying overall mobility in children with cerebral palsy.
  • GMFM-66/88 should be used when you need to track changes in gross motor function over time.
  • MACS is best suited for assessing fine motor skills related to hand use in daily tasks.
  • BFMF is helpful for evaluating bimanual motor coordination and fine motor function.
  • HINE is the tool to use for early screening of neurological or motor impairments in infants.
  • Bayley-4 is your go-to for a comprehensive developmental assessment, covering motor, cognitive, and language domains in infants and toddlers.
  • TIMP is the most suitable for early motor control assessment in infants under 4 months.
