Motor Disorders

Diagnostic Criteria For Motor Disorders

Developmental Coordination Disorder (DCD)

Developmental Coordination Disorder is characterized by difficulties in the acquisition and execution of coordinated motor skills. These difficulties are manifested as clumsiness, slowness, and inaccuracy in the performance of motor skills. These motor skill deficits significantly and persistently interfere with daily living activities and impact academic/school productivity, vocational pursuits, leisure, and play.

Stereotypic Movement Disorder

Stereotypic Movement Disorder involves repetitive, seemingly driven, and purposeless motor behavior. Examples include hand flapping, body rocking, and head banging. The repetitive motor behavior interferes with social, academic, or other activities and may result in self-injury. Onset is in the early developmental period, and the behavior is not attributable to the physiological effects of a substance or another medical condition.

Tic Disorders

Tourette’s Disorder

Tourette’s Disorder is characterized by multiple motor and one or more vocal tics present at some time during the illness, although not necessarily concurrently. Tics occur many times a day, nearly every day or intermittently, for more than one year, and the onset is before age 18.

Persistent (Chronic) Motor or Vocal Tic Disorder

This disorder is characterized by single or multiple motor or vocal tics, but not both, which have been present for more than one year, and the onset is before age 18.

Provisional Tic Disorder

Provisional Tic Disorder involves single or multiple motor and/or vocal tics that have been present for less than one year, and the onset is before age 18.

Presentation of Motor Disorders

Children

In children, Motor Disorders often present with noticeable clumsiness, difficulty in learning motor tasks, and repetitive movements. Children with Developmental Coordination Disorder may struggle with activities such as tying shoelaces, buttoning clothes, or using utensils. Those with Stereotypic Movement Disorder may exhibit repetitive behaviors such as hand flapping or body rocking, which can lead to social stigmatization and academic challenges. Children with Tic Disorders may have tics that interfere with their ability to concentrate in school and participate in social activities.

Teens

In adolescents, Motor Disorders can impact self-esteem and social relationships. Teens with Developmental Coordination Disorder might avoid sports or physical activities due to fear of embarrassment. Those with Stereotypic Movement Disorder may face increased social isolation as peers become less tolerant of atypical behaviors. Teens with Tic Disorders may experience an increase in tic severity during stressful periods, which can exacerbate difficulties in academic and social settings.

Adults

In adults, Motor Disorders can affect occupational performance and social interactions. Adults with Developmental Coordination Disorder may find certain job tasks challenging, particularly those requiring fine motor skills or coordination. Stereotypic Movement Disorder may continue to impact daily functioning, particularly if the repetitive behaviors are self-injurious. Adults with Tic Disorders may develop coping mechanisms to manage their tics, but stress and fatigue can still exacerbate symptoms, affecting work and social life.

Males

Motor Disorders are more commonly diagnosed in males than females. Males with Developmental Coordination Disorder often present with noticeable difficulties in motor coordination and are more likely to be referred for assessment due to disruptive behaviors in school. Males with Stereotypic Movement Disorder may exhibit more severe repetitive behaviors, increasing the risk of self-injury. Tic Disorders, including Tourette’s Disorder, are also more prevalent in males, with tics typically appearing earlier and being more pronounced.

Females

Females with Motor Disorders may be underdiagnosed or misdiagnosed due to subtler presentations of symptoms. Girls with Developmental Coordination Disorder might be perceived as simply clumsy or unathletic, leading to delays in diagnosis and intervention. Females with Stereotypic Movement Disorder may exhibit repetitive behaviors that are less disruptive and therefore less likely to be noticed. Tic Disorders in females may present with fewer vocal tics and more motor tics, which can be overlooked or attributed to other causes.

Treatment Options for Motor Disorders

Children

Treatment for children with Motor Disorders often involves occupational therapy to improve motor coordination and daily living skills. Behavioral interventions can help manage repetitive behaviors associated with Stereotypic Movement Disorder and reduce the risk of self-injury. For children with Tic Disorders, behavioral therapy such as Comprehensive Behavioral Intervention for Tics (CBIT) can be effective in managing tic symptoms. Medication may also be considered in severe cases.

Teens

For adolescents, treatment strategies may include continued occupational therapy and behavioral interventions. Counseling or therapy can address the emotional and social challenges associated with Motor Disorders. Support groups can provide a sense of community and help teens develop coping strategies. In the case of Tic Disorders, medication and behavioral therapy may be combined to reduce tic severity and improve quality of life.

Adults

Adults with Motor Disorders can benefit from occupational therapy to address work-related challenges and improve daily functioning. Cognitive-behavioral therapy (CBT) can help manage anxiety and stress, which can exacerbate motor symptoms. Support groups and counseling can provide emotional support and practical advice for managing symptoms in professional and social settings. Medication may be used to manage severe symptoms of Tic Disorders.

Males

Treatment for males with Motor Disorders should include a focus on managing disruptive behaviors and improving motor skills. Behavioral interventions and occupational therapy can be particularly beneficial. For those with Tic Disorders, a combination of medication and behavioral therapy may be necessary to manage symptoms effectively. Support from educators and family members is crucial to help males with Motor Disorders succeed academically and socially.

Females

Treatment for females with Motor Disorders should consider their unique presentation of symptoms and potential underdiagnosis. Interventions might focus on building self-esteem and addressing any co-occurring conditions such as anxiety or depression. Occupational therapy can improve motor skills and daily functioning, while behavioral therapy can help manage repetitive behaviors and tics. Supportive counseling and therapy can provide emotional support and help females develop effective coping strategies.
