**Core Concept**
Scissors gait is a type of abnormal gait pattern characterized by a crossing of the legs during walking, resembling the motion of scissors. This gait pattern is typically seen in patients with neurological disorders that affect the motor control of the lower limbs.

**Why the Correct Answer is Right**
Scissors gait is often associated with cerebral palsy, a neurological disorder that affects movement and muscle tone. In cerebral palsy, the abnormal muscle tone and coordination lead to an inability to control the movement of the legs properly, resulting in a crossing of the legs during gait. This is due to the spasticity of the adductor muscles and the weakness of the hip abductors.

**Why Each Wrong Option is Incorrect**
**Option A:** Hemiplegia - Hemiplegia is a condition characterized by weakness or paralysis of one side of the body, but it does not typically cause scissors gait.
**Option B:** Parkinson's disease - Parkinson's disease is a neurodegenerative disorder that affects movement, but it typically causes a shuffling gait rather than scissors gait.
**Option C:** Spinal cord injury - Spinal cord injury can cause a variety of gait abnormalities, but scissors gait is not a common feature.

**Clinical Pearl / High-Yield Fact**
Cerebral palsy is a leading cause of childhood disability, and scissors gait is a common feature of spastic diplegic cerebral palsy, which affects the lower limbs.

**Correct Answer:** C. Spinal cord injury
