Which best describes the extension synergy pattern of the leg?

• A. Hip flexion, adduction, internal rotation; knee flexion
• B. Hip extension, adduction, internal rotation; knee extension
• C. Knee flexion, external rotation; hip extension
• D. Hip adduction, abduction; knee extension

Answer: (B)

The extension synergy pattern of the leg is characterized by specific positions of the hip and knee during extension. In this pattern, the hip is positioned in extension, adduction, and internal rotation, while the knee is fully extended. This is often observed in patients with neuromuscular conditions, where the use of synergies is common due to impaired motor control. Understanding this synergy is key for clinicians when evaluating and assisting patients with movement disorders or after neurological events, such as strokes. Recognizing the extension pattern allows for the development of effective rehabilitation strategies, orthotic management, and the planning of physical therapy to promote better movement dynamics. This synergy is an important concept in orthotics and rehabilitation, as it directly influences how practitioners approach treatment plans and interventions designed to restore functional mobility and improve quality of life for individuals with limb movement dysfunctions.
