Effective Language Therapy for Children with Dysarthria

Understanding Dysarthria in Children

Dysarthria is a motor speech disorder that affects the functioning of the speech and breathing muscles in children. It is caused by damage to the neurological system, which can be acquired or developmental. Acquired dysarthria may result from a haemorrhage to the brain, stroke, or traumatic brain injury. On the other hand, developmental dysarthria is usually secondary to conditions that children are born with or develop after birth [1].

Definition and Causes

Dysarthria is characterized by difficulties in the coordination and control of the muscles involved in speech production. It affects the speed, range, tone, strength, control, and accuracy of the movements required in speech. The severity and type of dysarthria depend on the amount and location of damage in the brain. There are six types of dysarthria that can occur in children [1].

The causes of dysarthria can be acquired or developmental. Acquired dysarthria is usually the result of an injury or damage to the neurological system, such as a haemorrhage, stroke, or traumatic brain injury. On the other hand, developmental dysarthria is typically associated with conditions that children are born with or develop after birth [1].

Impact on Speech Processes

Dysarthria can affect various processes involved in speech production. These include respiration (the control of breathing for speech), phonation (the production of vocal sounds), articulation (the movement of the tongue, lips, and jaw to form sounds), resonance (the modification of sound by the vocal tract), and prosody (the rhythm, stress, and intonation of speech).

The specific symptoms and impact of dysarthria on these speech processes can vary depending on the type and severity of the condition. Common symptoms include slurred speech, imprecise articulation, reduced volume, breathiness, monotone voice, and difficulty controlling the pitch and rhythm of speech [1].

Understanding dysarthria in children is crucial for providing appropriate speech therapy interventions. By addressing the underlying causes and understanding the impact on speech processes, speech-language therapists can develop personalized treatment plans to help children improve their communication abilities. In the next sections, we will explore the importance of speech therapy and the various techniques and approaches used to enhance communication skills in children with dysarthria.

Importance of Speech Therapy

Speech therapy plays a vital role in supporting children with dysarthria, a condition that affects their ability to produce clear and intelligible speech. By employing various therapeutic approaches, speech therapy enhances communication skills and improves overall quality of life for children with dysarthria.

Therapeutic Approaches

When it comes to treating dysarthria in children, speech and language therapists employ a range of therapeutic approaches to address the specific needs of each individual. These approaches are designed to reduce the effort required for speech production and increase the child's speech skills, making their speech more understandable to others [1].

Therapeutic approaches may include exercises to strengthen the muscles involved in speech production, techniques to slow down speech and improve articulation, strategies to increase vocal volume, and methods to improve overall respiratory control. Additionally, therapists may incorporate communication techniques such as gestures or writing to facilitate effective communication.

Enhancing Communication Skills

One of the primary goals of speech therapy for children with dysarthria is to enhance their communication skills. By working with speech-language pathologists, children can become more intelligible to others, improving their ability to communicate with parents, teachers, friends, and siblings [1]. This can significantly reduce frustration levels and enhance overall social interactions.

Speech and language therapists tailor treatment plans to address the specific needs and goals of each child. Treatment may include exercises to strengthen mouth muscles, techniques to slow down speech, strategies to speak louder and more clearly, movements to chew and swallow safely, and various communication techniques. These interventions aim to maximize the child's potential for effective communication and improve their overall quality of life.

In some cases, children with severe dysarthria may benefit from specialized programs such as RiteCare, offered by the California Scottish Rite Foundation. RiteCare clinics, staffed by licensed speech-language pathologists, provide tailored speech therapy, support, education to parents and caregivers, and assistive technology and devices to help children with severe dysarthria communicate effectively.

Speech therapy for children with dysarthria is a collaborative effort between therapists, children, and their families. The therapy aims to address the unique challenges of dysarthria, enhance communication skills, and promote successful interactions with the child's environment. By utilizing therapeutic approaches and enhancing communication skills, speech therapy empowers children with dysarthria to communicate effectively and participate fully in their daily lives.

Speech Therapy Techniques

When it comes to language therapy for children with dysarthria, speech therapy techniques play a crucial role in improving their communication abilities. These techniques focus on muscle strengthening exercises and articulation and vocal techniques to enhance speech production.

Muscle Strengthening Exercises

Muscle weakness is a common challenge faced by children with dysarthria. To address this, speech therapists often incorporate muscle strengthening exercises into their therapy sessions. These exercises target the muscles involved in speech production, such as those in the face, throat, and those used for breathing.

By engaging in targeted exercises, children can gradually strengthen these muscles, improving their control and coordination. Some examples of muscle strengthening exercises include:

Through consistent practice of these exercises, children can develop stronger and more coordinated muscles, leading to improved speech production.

Articulation and Vocal Techniques

Articulation and vocal techniques are another vital aspect of speech therapy for children with dysarthria. These techniques focus on improving the clarity and intelligibility of speech by targeting specific sounds, syllables, and vocal patterns. Speech therapists work closely with children to help them produce sounds accurately and intelligibly.

Some common articulation and vocal techniques used in therapy sessions include:

By incorporating these techniques into speech therapy sessions, children with dysarthria can work on their speech clarity, articulation, and vocal control. Over time, consistent practice and guidance from speech therapists can lead to significant improvements in their communication skills.

Remember, each child's therapy plan is individualized based on their specific needs and goals. Speech therapists tailor these techniques to suit the child's abilities and challenges, ensuring that therapy is effective and beneficial.

Home Speech Therapy Activities

When it comes to language therapy for children with dysarthria, consistent practice at home plays a vital role in improving their speech clarity and overall communication skills. Even short, regular practice sessions can lead to significant improvements over time [2]. Here are some key aspects to consider when engaging in home speech therapy activities:

Consistency and Practice

Consistency is key in speech therapy for children with dysarthria. Regular practice helps reinforce the skills learned during language therapy sessions and allows for the gradual development of new speech habits. It is essential to establish a routine that includes dedicated time for speech therapy activities. By incorporating these activities into daily life, children can work on their speech skills and make steady progress over time.

To ensure consistency, it can be helpful to set specific goals and track progress. This could involve keeping a record of the activities completed, noting any improvements observed, and celebrating milestones along the way. By making speech practice a regular part of the child's routine, they can develop a sense of ownership and motivation to engage in their therapy activities.

Tools and Techniques

Incorporating tools and techniques into home speech therapy activities can be highly beneficial for children with dysarthria. These tools provide additional support and make the practice sessions more engaging and effective. Here are a few examples:

It's important to note that while tools and techniques can enhance speech therapy activities, they should always be used under the guidance of a speech-language pathologist. They can provide guidance on selecting appropriate tools and techniques based on the child's specific needs and goals.

By incorporating consistency and utilizing various tools and techniques, parents and caregivers can actively participate in their child's language therapy journey. Consistent practice and engaging activities at home can significantly contribute to the child's progress in improving speech clarity and communication skills.

Specialized Treatment Approaches

When it comes to language therapy for children with dysarthria, there are specialized treatment approaches that have shown promising results. Two such approaches are Speech Intelligibility Treatment (SIT) and LSVT LOUD® Treatment.

Speech Intelligibility Treatment (SIT)

Speech Intelligibility Treatment (SIT) is a three-week intensive treatment program developed at Teachers College, Columbia University. Its primary focus is on improving speech intelligibility in children with dysarthria. SIT targets two key areas: articulatory working space and vocal intensity reductions.

During SIT, children are encouraged to speak with a "big mouth" and a "strong voice." The treatment aims to increase the range of movement in the articulatory muscles and enhance vocal intensity. By addressing these aspects, SIT helps children with dysarthria to produce clearer and more intelligible speech.

Studies have shown that SIT can lead to improved post-treatment speech intelligibility in both English-speaking and French-speaking children with dysarthria. This specialized approach can significantly contribute to enhancing communication skills and promoting overall language development in children with dysarthria.

LSVT LOUD® Treatment

Originally developed for adults with Parkinson's disease, LSVT LOUD® Treatment has also been adapted for children with dysarthria. This treatment approach focuses on improving speech production through intensive therapy sessions.

LSVT LOUD® Treatment emphasizes vocal loudness and clarity. It aims to increase vocal intensity, improve articulation, and enhance overall speech intelligibility. The treatment involves repetitive exercises and functional tasks that help children with dysarthria develop better control and coordination of their speech muscles.

Research has shown evidence of post-LSVT speech improvements in children with dysarthria [3]. LSVT LOUD® Treatment can be a valuable option for children with dysarthria, offering them the opportunity to enhance their communication skills and achieve more confident and intelligible speech.

It is important to note that these specialized treatment approaches should be conducted by qualified speech-language pathologists who have expertise in working with children with dysarthria. The treatment plans are tailored to meet individual needs and may include a combination of techniques and strategies from other language therapy approaches.

By utilizing specialized treatment approaches such as SIT and LSVT LOUD®, speech-language pathologists can help children with dysarthria make significant progress in their speech intelligibility and overall communication abilities. These treatments, along with consistent practice and support from therapists and caregivers, contribute to empowering children with dysarthria to communicate effectively and confidently.

Long-Term Management

After undergoing speech therapy, long-term management is essential for children with dysarthria to maintain and further improve their communication skills. Two key aspects of long-term management include the generalization of skills and ongoing support and education.

Generalization of Skills

Generalization refers to the ability to transfer newly acquired speech skills from the therapy setting to real-world environments and daily interactions. It plays a crucial role in ensuring ongoing intelligibility success for children with dysarthria. By incorporating generalization practice directly into treatment sessions, speech-language pathologists can help children apply their new strategies in practical situations.

For example, therapy activities may involve ordering food at a cafeteria, engaging in conversations with peers, or creating surveys to gather information. These real-life scenarios provide opportunities for children to apply their newly acquired speech habits and adapt them to different communication contexts. Continued practice and exposure to diverse situations contribute to the generalization of skills and enhance overall communication effectiveness.

Support and Education

Ongoing support and education are vital components of long-term management for children with dysarthria. Parents, caregivers, and teachers play crucial roles in supporting and reinforcing the communication skills learned during therapy. They should be provided with resources and guidance to help facilitate the child's progress outside of formal therapy sessions.

Programs like RiteCare, offered by the California Scottish Rite Foundation, provide speech and language services to children with communication disorders, including dysarthria. These programs often involve licensed speech-language pathologists who specialize in diagnosing and treating communication disorders. They offer tailored speech therapy, support, education to parents and caregivers, and assistive technology and devices to help children with severe dysarthria communicate effectively.

In addition to professional support, parents and caregivers can also benefit from educational resources and workshops that provide them with a deeper understanding of dysarthria and effective strategies for supporting their child's communication needs. By staying informed and actively engaging in their child's speech development, parents can create a supportive environment that fosters continued progress and success.

By focusing on the generalization of skills and providing ongoing support and education, long-term management for children with dysarthria ensures the maintenance and improvement of their communication abilities. With consistent practice, reinforcement, and access to resources, children with dysarthria can continue to thrive and communicate effectively in various settings.
