Introduction and background

Cerebral palsy (CP) is a complex and heterogeneous group of non-progressive, lifelong motor disorders originating from early brain development and characterized by varying degrees of movement dysfunction. CP is one of the most prevalent childhood neurological conditions globally, affecting approximately two to three per 1,000 live births. It presents a significant challenge to affected individuals, their families, and healthcare providers due to its wide-ranging impact on motor function, communication, and daily life [1-3].

The term “cerebral palsy” encompasses a spectrum of motor impairments, manifesting as spasticity, dyskinesia, ataxia, or a combination thereof. These motor disturbances result from brain damage or abnormal brain development before, during, or shortly after birth. While CP is non-progressive, its clinical presentation can evolve due to growth and aging. Understanding the nuances of this condition is vital for effective management and intervention [4].

Assessment plays a pivotal role in the management of individuals with CP. It serves as the foundation upon which healthcare professionals, educators, and caregivers develop tailored interventions, monitor progress, and make informed decisions about treatment strategies. Assessment in CP extends beyond mere diagnosis; it encompasses the comprehensive evaluation of an individual's motor abilities, communication skills, cognitive function, and overall quality of life [5].

The multidimensional nature of CP necessitates a systematic and standardized approach to assessment. Precise and objective assessment tools enable clinicians to characterize an individual's condition accurately, identify specific areas of impairment, and track changes over time. Moreover, assessments provide the basis for setting realistic goals and evaluating the effectiveness of therapeutic interventions. In essence, assessment empowers healthcare teams to provide targeted, evidence-based care that enhances individuals with CP's well-being and functional independence [6].

This review aims to provide a comprehensive examination of the assessment scales and tools used to evaluate individuals with CP. We will delve into various aspects of CP assessment, including the most employed assessment scales, their applications in clinical practice, and the emerging trends and challenges within this field. By synthesizing existing knowledge and highlighting recent developments, this review aims to assist healthcare professionals, researchers, and educators in making informed decisions regarding selecting and implementing assessment tools for individuals with CP.

Review

Background on CP

Etiology and Causes of CP

CP, a complex neurological condition, can arise from many factors, broadly categorized into four distinct groups. First, prenatal factors encompass a range of conditions and exposures during pregnancy that may contribute to the development of CP. These include maternal infections, exposure to harmful toxins or drugs, and genetic factors that may increase the risk of brain abnormalities in the developing fetus. Second, perinatal factors occurring around birth are another critical dimension [7]. Events such as birth asphyxia, premature birth, low birth weight, and complications during delivery can significantly increase the likelihood of CP. Third, postnatal factors come into play when brain injuries occur after birth [8]. These injuries can result from head trauma, infections, strokes, or other neurological insults, further highlighting the multifactorial nature of CP causation. Finally, and perhaps most perplexing, are the cases where the exact etiology of CP remains unknown. These instances underscore the complexity of the condition, suggesting that a combination of factors or genetic predispositions may interplay to contribute to the development of CP [8].

Prevalence and Demographics

Global prevalence: CP is a notable global prevalence, affecting approximately two to three per 1,000 live births worldwide. However, it is essential to recognize that prevalence rates vary considerably between countries and regions. These disparities are attributed to a complex interplay of factors, including differences in healthcare access, the quality of perinatal care, and socioeconomic conditions. Regions with limited access to advanced medical care may have higher rates of CP due to challenges in preventing and managing risk factors during pregnancy and birth [9].

Age of diagnosis: The diagnosis of CP typically occurs in early childhood, often within the first two years of a child's life. This early diagnosis is prompted by recognizing motor development delays, as children with CP may exhibit distinctive signs such as delayed crawling, walking, or reaching developmental milestones. Early diagnosis is crucial as it facilitates timely interventions and access to support services that significantly improve outcomes [3].

Gender: CP does not discriminate by gender, affecting both males and females. While there is a slight predominance of CP in males, this gender difference is generally not considered significant. CP is an inclusive condition, and its impact varies widely among affected individuals, irrespective of gender. Therefore, comprehensive assessment and support should be provided to all individuals with CP, regardless of gender [10].

Socioeconomic factors: Socioeconomic factors play a substantial role in the risk and prevalence of CP. Children born into disadvantaged socio-economic backgrounds may face a higher risk of CP due to various challenges, including limited access to quality prenatal care, healthcare services, and nutritional support. Socioeconomic disparities can impact the early identification and management of risk factors during pregnancy and childbirth. Therefore, addressing these disparities and improving healthcare access for vulnerable populations is essential in reducing the burden of CP and ensuring equitable care for all children [11].

Types and Classification of CP

Spastic CP: Spastic CP is the most prevalent form, affecting approximately 70%-80% of individuals with CP. It is characterized by increased muscle stiffness and tone, resulting in stiff and sometimes jerky movements. The severity of spastic CP can vary widely, and it may affect specific limbs (monoplegia), one side of the body (hemiplegia), or all four limbs (quadriplegia). Spasticity can lead to mobility challenges, contractures, and difficulties in fine motor control [12].

Dyskinetic CP: Dyskinetic CP is characterized by involuntary and uncontrolled movements ranging from slow and writhing (athetoid) to repetitive and spasmodic (dystonic). Individuals with dyskinetic CP often struggle to control their posture and coordinated movements. These uncontrollable movements can make everyday activities, such as feeding and communication, challenging and exhausting [13].

Ataxic CP: Ataxic CP is distinguished by poor coordination, balance, and shaky, imprecise movements. Individuals with ataxic CP may struggle with tasks requiring fine motor skills, such as writing or buttoning a shirt. Their gait may appear unsteady, with a wide-based stance, making walking and balance challenging [14].

Mixed CP: In some cases, individuals exhibit a combination of features from the types, leading to a diagnosis of mixed CP. This can present unique challenges as individuals may experience complex symptoms, including spasticity, dyskinesia, and ataxia. The specific manifestations and severity vary widely among individuals with mixed CP [15].

Assessment in CP

Objectives of Assessment

Diagnosis: One of CP assessment's primary and foundational objectives is facilitating an accurate diagnosis. Early diagnosis, often within the first two years of life, is pivotal as it allows for timely and targeted interventions and support. This ensures that individuals with CP receive the care they need as soon as possible, increasing the potential for improved outcomes [16].

Researchers can make informed advancements in the field by collecting and analyzing assessment data, ultimately leading to more effective assessment and treatment strategies [20].

Challenges in CP Assessment

Heterogeneity of CP: CP is marked by a significant degree of heterogeneity, with a broad spectrum of motor impairments, associated disabilities, and varying levels of cognitive function. This inherent diversity poses a challenge when developing assessment tools. A one-size-fits-all approach may not capture individuals' nuanced needs and abilities with CP. Therefore, assessment tools must be flexible and adaptable to accommodate the unique profiles of each person [1].

Communication difficulties: Communication difficulties are common among individuals with CP, affecting their ability to participate in traditional assessment methods. Many individuals may have limited verbal communication skills, necessitating the consideration of alternative communication strategies. Augmentative and alternative communication (AAC) tools and techniques, such as communication boards or devices, should be integrated into the assessment process to ensure that individuals with CP can effectively express their needs and preferences [21].

Aging and changing needs: As individuals with CP progress through different stages of life, their needs and abilities may change significantly. Assessment must be an ongoing and dynamic process that adapts to these evolving requirements. Pediatric assessments may focus on developmental milestones, while assessments for adults may emphasize functional independence and quality of life. Regular re-evaluation ensures that interventions remain aligned with the changing needs of individuals with CP [22].

Inter-rater reliability: Achieving consistent assessment results can be challenging due to potential variations in the interpretation of assessment tools by different healthcare professionals. Maintaining high inter-rater reliability is crucial to ensure that assessment outcomes are accurate and reliable. This can be achieved through standardized training, calibration exercises, and ongoing collaboration among healthcare providers to align assessment practices [23].
