from 9 months to 15 months, describe the physical characteristics of a baby that have the greatest impact on their gait.
- Center of Mass (Lower Thoracic Level)
- This is due to the head being proportionally larger than the body - High Fat to Muscle Mass Ratio
- Contributes to Weakness
What are the Standing Posture characteristics of a baby (9mo-15mo)
- Wide Base of Support
- Hip Abduction, flexion
- Excessive Femoral Anteversion
- Knee Varus
- Tibia IR
- Heel Everted
What are the Gait Characteristics of a baby (9mo-15mo)?
- Wide Base of Support
- good for med/lat stability
- Head must remain within BOS to maintain balance - Full foot initial contact
- Increases stability - Decreased Stride Length
- Increased Cadence
- Foot Drop in Swing
Muscle activation for a baby is dominated by _______________?
co-Contraction
Gastrocnemius/Anterior Tibialis during Swing
Quadriceps/Hamstrings during Stance
For a baby, what are the 3 factors limiting their GAIT functions?
- Decreased Extensor Strength
- (Anterior/Posterior Stability limited) - Poor Dynamic Balance
- Limited Postural Control (Head/Trunk)
From 18mo to 24mo, what are the 3 pysical characteristic changes?
- Increased Neurological Maturation
- Increased Walking Experience
- Lower Center of Mass
What happens to a standing posture from 9-15mo to 18-25mo?
- (Decreased) Hip Abduction
- (Decreased) Anteversion
- (Decreased) Knee Varus
- Heel Remains Everted
- (Decreased) Base of Support
What are the changes in GAIT characteristics from 9-15mo to 18-25mo?
- (Decreased) Base of Support
- Allows for increased Ant/Post movement over supporting foot - Emerging Loading response Knee Flexion
- Eccentric Muscle control - (Decreased) Co-Contraction
What changes in Physical characteristics are present in children 3-3.5yrs?
- Center of Mass is closer to the extremities as the rate of lower extremity growth stabilizes
- Balance mechanisms still developing
- Visual and Vestibular systems still immature
How does the standing posture of a 3-3.5yr old change from previous age?
- Emergence of KNEE VALGUS
- (Decreased) Eversion at Heel
- (Decrease) in Femoral Anteversion
What are the Gait changes for a 3-3.5yr old?
- More adult like Kinematics and EMG Patterns
2. Joint Torques remain somewhat immature
What are they physical characteristic changes from when a child reaches 6-7 yrs of age?
- Period of Disproportionate growth has passed.
2. Center of mass still higher than adults (L3)
How do the standing postures change from previous years to 6-7yrs of age?
- Normal Tibiofemoral Angle
- Neutral Heel
- Continued decrease in Femoral Anteversion
How do the Gait characteristics change from previous years to 6-7yrs of age
- Minimal differences in Kinematics and Kinetic when compared to Adults
- Temporal-Spatial Parameters continue with age
