What is the core principle of CIMT in pediatric CP?

• A. Restricting the unaffected hand to encourage use of the affected hand.
• B. Strengthening all limbs equally.
• C. Surgical tendon lengthening.
• D. Pharmacologic relaxation.

Answer: (A)

CIMT works by forcing use of the affected hand to overcome learned non-use. By restricting the unaffected hand (often with a constraint or glove) and pairing that with intensive, repetitive practice of meaningful tasks with the affected hand, children are encouraged to actively use and improve the function of the weaker limb. This constraint-driven practice aims to drive neuroplastic changes and increase spontaneous use of the affected hand in daily activities. The other approaches describe different treatment directions: general strengthening of both limbs doesn’t specifically address the asymmetry in hand use CIMT targets; surgical tendon lengthening is a structural procedure to address contractures, not a constraint-based therapy; pharmacologic relaxation involves medications to reduce spasticity, not a practice-driven method to promote use of the affected hand.
