Brooks Rehabilitation
2026


• Physiological Flexion
o Prone: with rotation, elbow flexion, hands fisted, wrist neutral, shoulder abduction and forward tilted scapula, fingers held more fisted in supine
o Leg abduction, feet (praying position), hip flexion, knee flexion

• Random extremity movements of UEs and LEs
• Little independent control of any body part
• Total head lag with pull to sit
• Primary standing and automatic walking

• Hands are closed most of the time but may start to open
• Arm movements are random
• Vision is very blurry—babies can see high contrast pictures (black and white)
