A nurse is assessing a 3-year-old child with spastic cerebral palsy. Which assessment finding would be most indicative of the child's need for immediate intervention?

## 보기

1. Scissoring gait pattern when attempting to walk
2. Difficulty with fine motor skills such as grasping small objects
3. Delayed speech development with unclear articulation
4. Sudden onset of increased muscle rigidity with fever and altered mental status **✔ 정답**

**정답: 4**

## 해설

Sudden onset of increased muscle rigidity with fever and altered mental status indicates a serious complication like infection or seizure requiring immediate intervention. Other options are typical chronic symptoms of cerebral palsy.

Understanding the Priority: Recognizing an Acute Neurological Change

When caring for a child with spastic cerebral palsy (CP), it is essential to distinguish between chronic, baseline symptoms of the condition and acute changes that signal a new or worsening pathology. Spastic CP is a permanent disorder of movement and posture development resulting from a non-progressive insult to the developing fetal or infant brain [2]. Because the underlying brain injury is static, the typical motor impairments—such as increased muscle tone and coordination difficulties—are chronic and generally stable. A sudden, dramatic shift in neurological status is not a feature of CP itself and requires immediate investigation.

Analyzing the Assessment Findings

Let's examine each option to understand why a sudden onset of symptoms is the priority.

**Option 1: Scissoring gait pattern when attempting to walk.** A scissoring gait, where the legs cross over each other due to tight hip adductor muscles, is a classic and expected manifestation of spastic diplegia, a common form of CP. This results from the chronic hypertonicity and altered muscle architecture characteristic of the condition [3]. While it requires management with therapies such as stretching and orthotics, it is a baseline finding, not an emergency [3].

**Option 2: Difficulty with fine motor skills such as grasping small objects.** Difficulty with fine motor tasks stems from the spasticity and impaired motor control affecting the upper extremities. Like the gait pattern, this is a chronic manifestation of the underlying, non-progressive brain lesion [2]. It represents a long-term functional challenge that is addressed through occupational and physical therapy, not an acute crisis.

**Option 3: Delayed speech development with unclear articulation.** Dysarthria and speech delays are common co-morbidities in CP due to impaired neuromuscular control of the oral-motor structures. The literature notes that speech impairment can be a presenting feature in various neurological conditions affecting motor pathways, including CP . This is a developmental issue requiring speech-language pathology intervention, not a finding that triggers an immediate medical emergency response.

**Option 4: Sudden onset of increased muscle rigidity with fever and altered mental status.** This cluster of symptoms represents an acute and dramatic change from baseline. A child with CP has a pre-existing, stable level of spasticity. The *sudden* worsening of this rigidity, especially when accompanied by fever and a change in consciousness, is a red flag for an acute neurological or systemic process. This could indicate a serious condition such as sepsis, meningitis, a new intracranial event, or a severe metabolic crisis. For instance, inborn errors of metabolism, like arginase 1 deficiency, can present with progressive spasticity and episodic hyperammonemia, which can be triggered by illness and lead to acute neurological decompensation and altered mental status . This is not an exacerbation of CP; it is a superimposed, life-threatening event. The immediate priority is to assess airway, breathing, and circulation, notify the provider urgently, and prepare for diagnostic tests like blood cultures and a sepsis workup.References (research sources)

## 임상 시나리오

Recognizing Acute Changes in Spastic CPDifferentiating Baseline Symptoms from Emergencies
In children with spastic cerebral palsy, the underlying brain injury is static. Therefore, motor impairments like scissoring gait or fine motor delays are chronic and stable.

A sudden onset of increased muscle rigidity accompanied by fever and altered mental status is a red flag. This is not a feature of CP and suggests an acute neurological or systemic insult.

Emergency ActionImmediately report any acute change in neurological status. Prioritize assessing airway, breathing, and circulation, and prepare for urgent diagnostic workup to rule out infection, hemorrhage, or seizure.

## 핵심 개념

- **Spastic Cerebral Palsy** — A permanent movement and posture disorder from a non-progressive brain injury, characterized by hypertonia and exaggerated reflexes.
- **Scissoring Gait** — A gait pattern where legs cross over due to tight hip adductor muscles, commonly seen in spastic diplegia.
- **Altered Mental Status** — An acute change in consciousness or cognition indicating a potentially life-threatening neurological or systemic insult.
- **Hypertonia** — Abnormally increased muscle tone or rigidity, a hallmark of upper motor neuron lesions like spastic CP.
