How can intervention be tailored to improve energy efficiency of gait in CP?

• A. Align joints with orthotics, reduce spasticity, train selective motor control, strengthen proximal muscles, and optimize walking speed.
• B. Focus only on distal strengthening without considering alignment.
• C. Increase walking speed without addressing spasticity.
• D. Rely on passive stretching alone.

Answer: (A)

Improving energy efficiency of gait in cerebral palsy comes from addressing multiple interacting factors that shape how the body moves during walking, not from one single change. Aligning joints with orthotics helps create a more normal foot–ankle and knee–hip trajectory, improving the ankle rocker and push-off mechanics. When joints are better aligned, movement becomes smoother and less energy is wasted on compensatory patterns, which directly lowers the metabolic cost of walking. Reducing spasticity is important because high tone and rapid reflexive resistance can cause co-contraction and stiff, inefficient movements. By lowering spasticity, muscles can lengthen and shorten more predictably, allowing smoother, more fluid gait with less unnecessary effort. Training selective motor control supports this by improving the ability to activate muscles in the correct sequence for the task of walking. Better motor control reduces the energy drain from inappropriate or excessive muscle co-activation and helps the body use its muscles more efficiently during each step. Strengthening proximal muscles, especially the trunk and hip girdle, provides a stable core and pelvis, which enhances balance and trunk orientation during stance and swing. This stability translates to more efficient limb movements and less energy spent compensating for instability. Finally, optimizing walking speed recognizes that energy cost changes with speed. There is an efficient speed range for gait, and interventions should aim to bring the person toward that range while ensuring control and safety. Merely walking faster without addressing underlying motor control, tone, and alignment often increases energy expenditure or reduces stability. The other options fall short because they focus on a single aspect (distal strengthening, increasing speed, or passive stretching) without addressing the integrated factors that drive energy-efficient gait in CP.
