مريض بعد طعنة في الظهر عنده ضعف في الرجل اليمنى وفقدان الإحساس بالألم والحرارة في الرجل اليسرى. ما المتلازمة؟

After a stab wound to the back, a client has right-leg weakness and loss of pain and temperature sensation in the left leg. Which syndrome is this?

1. Brown-Séquard (hemisection) syndrome
2. Isolated sciatic nerve injury
3. Anterior cord syndrome
4. Central cord syndrome

Answer: A) Brown-Séquard (hemisection) syndrome. Cord hemisection causes ipsilateral weakness and loss of proprioception with contralateral loss of pain and temperature, because those fibres cross in the cord.
