The VML method was developed in Israel, in Hebrew, through clinical experiences with children with CAS. VML is a structured method that involves:
1. Integrative evaluation using a specific evaluation form and protocol:
2. Integrative analysis using a specific analysis form:
3. Forming a treatment plan with a specific treatment plan form and
4. hands-on techniques.
5. The use of motor learning principles in treatment
The method uses motor learning principles which consider CAS as a motor planning oriented problem. Nevertheless, language and communication goals have a major weight in the evaluation, the analysis and the treatment plan. In addition, each vowel, consonant, syllable and word have special techniques that assist the child in learning to imitate the desired sound. While originally based on the Hebrew language, over the last few years several English speaking children were treated with VML in English.
The VML method was translated into English, Romanian, Polish, Slovenian, Russian and Mandarin in order to enable different languages speakers to use it. Autism and CAS were the the target populations in the early years that VML was used to treat children. In the past few years there has been more experience with a variety of syndromes as well as with pure CAS at different severity levels; from children who have no verbal ability at all and who have severe oral motor apraxia, to children with minor deficits in speech. The treatment age ranges from a year and a half to fifteen years of age.
The treatment delivery and goals differ according to the child’s age. VML can also serve adults with Apraxia of Speech (AOS). AOS, unlike CAS, is an acquired syndrome due to trauma to the brain at an older age. VML can help children with CAS or other speech delays (mainly of motor origin). There is no age restriction in treatment using VML, although the treatment plan would vary according to the patient’s age.
